  1. Tarski biography
    • These appointments were of great significance since Alfred took a course on logic given by Lesniewski who quickly saw his genius and persuaded him to change from biology to mathematics.
    • Tarski taught logic at the Polish Pedagogical Institute in Warsaw from 1922 to 1925 then in that year he was appointed Docent in mathematics and logic at the University of Warsaw.
    • which is among the most important papers ever written on mathematical logic.
    • Not only does this paper provide a mathematically rigorous articulation of several ideas that had been developing in earlier mathematical logic, it also presents foundations on which later logic could be built.
    • This work on logical consequence has had a profound influence and has been discussed by many authors; see for example [Tarski on truth and logical consequence (Stanford, Ca., 1986).',5)">5], [Modern Logic 7 (2) (1997), 109-130.

    • In 1937 he published another classic paper, this time on the deductive method, which presents clearly his views on the nature and purpose of the deductive method, as well as considering the role of logic in scientific studies.
    • His seminars at Berkeley fast became a power-house of logic.
    • Tarski made important contributions in many areas of mathematics: set theory, measure theory, topology, geometry, classical and universal algebra, algebraic logic, various branches of formal logic and metamathematics.
    • He produced axioms for 'logical consequence', worked on deductive systems, the algebra of logic and the theory of definability.
    • In 1968 Tarski wrote another famous paper Equational logic and equational theories of algebras in which he presented a survey of the metamathematics of equational logic as it then existed as well as giving some new results and some open problems.
    • is one of the finest pieces of expository writing in all of mathematical logic.
    • His work includes Geometry (1935), Introduction to Logic and to the Methodology of Deductive Sciences (1936), A decision method for elementary algebra and geometry (1948), Cardinal Algebras (1949), Undecidable theories (1953), Logic, semantics, metamathematics (1956), and Ordinal algebras (1956).
    • Introduction to Logic and to the Methodology of Deductive Sciences is an introduction written at the level of an undergraduate course in logic and axiomatics.
    • It is only when we see Tarski's papers collected in one place that we can begin to appreciate the scope and profundity of his influence on modern mathematical thought and, in particular, on modern mathematical logic.
    • Mathematical logic as we know it today is almost inconceivable without Tarski's contributions.
    • He was made honorary editor of Algebra Universalis and served as President of the Association for Symbolic Logic from 1944 to 1946 and the International Union for the History and Philosophy of Science in 1956-57.

  2. Curry biography
    • He was given a topic in the theory of differential equations by George Birkhoff but he began reading books on logic which seemed to him far more interesting that his research topic.
    • He asked various faculty members at Harvard, and Norbert Wiener at MIT, if they thought he might change to undertake research in logic.
    • He again approached various faculty members at Harvard, and Norbert Wiener at MIT, asking whether they thought that he might write his doctoral dissertation on logic.
    • Wiener's reply was typical - avoid logic unless you have something to say, but now you certainly have something to say! .
    • Curry now made his final change in direction and decided to give up his doctoral studies on differential equations and to write a doctoral dissertation on logic.
    • Some papers published during the early years of his research include The universal quantifier in combinatory logic (1931), Some additions to the theory of combinators (1932), Apparent variables from the standpoint of combinatory logic (1933), and Some properties of equality and implication in combinatory logic (1934).
    • The Association for Symbolic Logic was founded in 1936 with Curry as one of the founders.
    • His retiring presidential address The combinatory foundations of mathematical logic was published in the Journal of Symbolic Logic in 1942.
    • After giving a very clear exposition of the fundamentals of combinatory logic, showing its close relationship to the λ-calculus developed by Church, Curry went on to describe his recent work.
    • He had examined simplified methods of deriving the paradoxes (such as those of Richard and Russell) in systems of logic which are inconsistent, and had also developed a method of introducing into combinatory logic undefined notions of generality, such as quantification or formal implication, in such a way that a consistency theorem like that of Church and Rosser could still be derived.
    • His major texts include Combinatory Logic (1958) (with Robert Feys), and Foundations of Mathematical Logic (1963).
    • Curry began working on Combinatory Logic in 1950 when he was awarded a Fulbright Grant that enabled him to work with Robert Feys at Louvain.
    • E J Cogan, reviewing the book, gives a nice description of combinatory logic:- .
    • Combinatory logic is concerned with certain basic notions of the foundations of mathematics which are usually used in an intuitive and unanalysed way.
    • The part of combinatory logic which is concerned with questions of a fundamental nature which, like substitution, involve variables, is called the theory of combinators.
    • In Foundations of Mathematical Logic Curry develops the topic from an algebraic basis using Gentzen's methods.
    • In 1966 he accepted the position of Professor of Logic, History of Logic, and Philosophy of Science at Amsterdam.
    • The authors of [To H B Curry : essays on combinatory logic, lambda calculus and formalism (London-New York, 1980), vii-xi.',3)">3] make some nice comments about Curry and his wife:- .
    • And this has undoubtedly been an important contribution to the enthusiasm of many of those of us working in combinatory logic.
    • There are always many parties and other, less formal gatherings, and we conjecture that Virginia's cooking has also played a role in the growth of interest in combinatory logic.

  3. Schroder biography
    • Dipert [Modern Logic 1 (2-3) (1990/91), 117-139.',12)">12] speculates that his reasons for going to Zurich may not have been entirely academic ones since he was a very enthusiastic mountain climber and made a number of difficult ascents without a guide during his time in Switzerland.
    • Ernst Schroder's important work is in the area of algebra, set theory and logic.
    • However, he never considered himself to be a logician, as Peckhaus points out [Bulletin of Symbolic Logic 5 (1999), 433-450.',22)">22]:- .
    • What was the connection between logic and algebra in Schroder's research? ..
    • In fact Schroder started out being interested in mathematical physics, and his move towards logic was simply an attempt to deepen its foundations.
    • Now one sees Schroder moving towards logic with Lehrbuch der Arithmetik und Algebra fur Lehrer und Studierende published by Teubner in 1873.
    • He wrote his first work on mathematical logic Der Operationskreis des Logikkalkuls, influenced by George Boole and Hermann Grassmann, in 1877.
    • He was the first to use the term 'propositional calculus' and seems to be the first to use the term 'mathematical logic'.
    • In fact he compares algebra and Boole's logic saying:- .
    • In Vorlesungen uber die Algebra der Logik, a large work published between 1890 and 1905 (it was edited and completed by Eugen Muller after his death), Schroder gave a detailed account of algebraic logic, provided a source for Alfred Tarski to develop the modern algebraic theory and gave an extensive bibliography of the history of logic.
    • Brady writes [From Pierce to Skolem: A Neglected Chapter in the History of Logic (Elsevier, 2000).',3)">3]:- .
    • Schroder's concept of solving a relational equation was a precursor of Skolem functions, and he inspired Lowenheim's formulation and proof of the famous theorem that every sentence with an infinite model has a countable model, the first real theorem of modern logic.
    • Schroder said his aim was (see for example [Bulletin of Symbolic Logic 5 (1999), 433-450.',22)">22]):- .
    • to design logic as a calculating discipline, especially to give access to the exact handling of relative concepts, and, from then on, by emancipation from the routine claims of natural language, to withdraw any fertile soil from "cliche" in the field of philosophy as well.
    • Brady writes [From Pierce to Skolem: A Neglected Chapter in the History of Logic (Elsevier, 2000).',3)">3]:- .
    • Schroder considered quantifiers (or, at least, sums and products equivalent to quantifiers for a fixed domain) in first- and higher-order logic.
    • He understood that there are notions such as countability that are beyond relative calculus (and also beyond first-order predicate logic).
    • Dipert [Modern Logic 1 (2-3) (1990/91), 117-139.',12)">12] gives an interesting account of Schroder's character which he compares with that of Peirce:- .
    • When I started to trace the later development of logic, the first thing I did was to look at Schroder's 'Vorlesungen uber die Algebra der Logik', ..
    • [whose] third volume is on the logic of relations (Algebra und Logik der Relative, 1895).
    • The three volumes immediately became the best-known advanced logic text, and embody what any mathematician interested in the study of logic should have known, or at least have been acquainted with, in the 1890s.
    • Schroder participated in the development of mathematical logic as an independent discipline in the second half of the nineteenth century.
    • As a result he was an outsider, at a disadvantage in chosing terminology, in outlining his argumentation, and in judging what mathematical logic could accomplish.

  4. Scholz biography
    • This marked an important change in the direction of Scholz's research for at this time his interests turned towards mathematical logic.
    • In [Mathematicians under the Nazis (Princeton University Press, 2003).',3)">3] Segal suggests that Scholz's love of structure was also important in his move into mathematical logic:- .
    • Of course for someone like Scholz, who had trained in theology and then philosophy, mathematical logic involved a deep understanding of mathematics which he had never studied.
    • Right from the time he arrived at Munster, Scholz worked towards building a school of mathematical logic there.
    • He gave lecture courses on mathematical logic and also lectured on the great philosophers.
    • In 1931 he published Geschichte der Logik, a short but erudite study, which looks at the history of results in logic leading to the study of mathematical logic.
    • pioneered the view that ancient and medieval logic was not something totally different (for better or for worse) from what modern logicians are doing by mathematical means.
    • The author was one of the first to see clearly that there is no better aid than modern logic to make clear what Aristotle, the Stoics, the Schoolmen and also a few post-Renaissance figures like Leibniz, were really after.
    • Logic 6 (1) (1941), 32-34.',4)">4]:- .
    • in his concluding summary that the philosophy which he intended is neither more nor less than mathematical logic, axiomatics ..
    • Apparently his view is that foundational research must first attain a more advanced stage, and at the same time the minds of philosophers must, in the school of mathematical logic and axiomatics, be turned to the spirit of clearness and precision - whose compatibility with philosophical profundity is stressed by Scholz in opposition to a frequent opinion - before a valuable speculative synthesis can be hoped for.
    • As we indicated above, Scholz's aim was to establish a world centre of mathematical logic at Munster.
    • By this time his research team at Munster were being referred to as "the Munster school of mathematical logic." The Technical University of Karlsruhe held Ernst Schroder's papers and Scholz was also successful in adding these to the growing collection of resources of his school [Philos.
    • Its title was changed again in 1943 to the Chair of Mathematical Logic and Foundational Questions in Mathematics.
    • In some ways the Nazi laws against the Jews helped Scholz establish Munster as an important centre for logic since the leading researchers in the other centres of Berlin and Gottingen were forced out.
    • However, Scholz was able to play the system to the advantage of mathematical logic by keeping on good terms with Nazis like Bieberbach.
    • Scholz's connections with Bieberbach had led earlier to funds being provided for a series of monographs on mathematical logic which had started in 1937.
    • What Scholz has understood is doubtless this, to obtain from the German State huge amounts of publication money for this logic production.
    • We fundamentally reject this logic which praises the English empiricists and sensory philosophers such as the Englishmen Locke, Berkeley, Hume, and by now find it really time to speak for once about the "Great Germans".
    • Scholz remained as head of the Institute for Mathematical Logic and Foundational Research at Munster until he retired in 1952.
    • The authors state (i) that mathematical logic is intended to provide a precise(r) formulation of the notion of consequence on which mathematical theories are based, (ii) that they consider those mathematical theories which fall within the scope of two-valued logic 'where every proposition is true or false'.

  5. Church biography

    • Symbolic Logic 3 (2) (1997), 154-180.',11)">11].
    • Church was a founder of the Journal of Symbolic Logic in 1936 and was an editor of the reviews section from its beginning until 1979.
    • In fact he published a paper A bibliography of symbolic logic in volume 4 of the Journal and he saw the reviews section as a continuation and expansion of this work.
    • in symbolic logic, wherever and in whatever language published ..
    • Symbolic Logic 4 (2) (1998), 172-180.',5)">5] highlights Church's guiding role in defining the boundaries of the discipline of symbolic logic through this editorial work and testifies to his unflagging industry and conscientiousness and his high editorial standards.
    • The aim of comprehensive coverage, which in 1936 had seemed quite practical, became less so as the years went by and by 1975 the rapid expansion in symbolic logic publications forced Church to give up this aspect and begin to provide only selective coverage.
    • Upon his retirement, Princeton was unwilling to continue accommodating the small staff working on the reviews for the Journal of Symbolic Logic.
    • Church wrote the classic book Introduction to Mathematical Logic in 1956.
    • This was a revised and very much enlarged edition of Introduction to mathematical logic which Church published twelve years earlier in 1944.
    • the first half of an introductory course in mathematical logic given to graduate students in mathematics [at Princeton in 1943].
    • Logic 18 (4) (1997), 211-232.',10)">10] that the 1956 edition of the book:- .
    • defined the subject matter of mathematical logic, the approach to be taken and the basic topics addressed.
    • Symbolic Logic 4 (2) (1998), 129-171.',3)">3].
    • Church considered this topic for about 40 years during the latter part of his career, beginning with his paper A formulation of the logic of sense and denotation in 1951.
    • Although most of Church's contributions are directed towards mathematical logic, he did write a few mathematical papers of other topics.

  6. Ackermann biography

    • This paper, written for non-experts in the subject, gives an excellent overview of how Ackermann viewed mathematical logic.
    • Symbolic Logic 23 (3) (1958), 342-343.',3)">3]:- .
    • An objection to mathematical logic is that it is not the same as the philosophical logic which forms the foundation of our thought and which alone is necessary for thinking.
    • Ackermann remarks that the traditional modes of inference are included in mathematical logic, besides many others, like the statement logic or the logic of relations.
    • One has the illusion of getting by with "Aristotelian logic" in mathematics just as long as mathematical reasonings are insufficiently analyzed.
    • A further objection to mathematical logic is that it is incomplete, in the sense that, by Godel's result of 1931 (the text says 1932), intuitively correct theorems cannot be proved within a given system.
    • Mathematical logic is of use in clarifying the concepts of "necessity" and "possibility," the distinction between "analytic" and "synthetic." Discussing the "triviality" of logic, the author presents the decision problem.
    • Ackermann presents intuitionism, which constructs a mathematics with a minimum of logic, and the Frege-Russell analysis of the number concept.
    • In these concepts "there is nothing foreign to logic." He concludes that "in the theory of natural numbers we have a domain which is capable of an intuitive foundation with a minimum of logic in the sense of [Brouwer] and also of attainment purely by logical definitions if we presuppose an extensive logic." .

  7. Poretsky biography
    • Although the main events of P S Poretsky's life and work have been known through obituaries such as [Izvestiya Fiziko-matematicheskogo obshchestva pri (Imperatorskom) kazanskom universitete, (2) 16 (1908), 3-7.',6)">6], it is only recently that further material on his life and work has come to light and this is described in [Modern Logic 3 (1) (1992), 93-94.',4)">4] and in more detail in [History of Science and Technology (Russian) 4 (2005), 64-73.',5)">5].
    • V A Bazhanov, the author of these papers, states in his summary of [Modern Logic 3 (1) (1992), 93-94.',4)">4]:- .
    • These include: various documents related to Poretsky's lectures on mathematical logic for mathematics department students at Kazan University which were intended to be given for three semesters in the autumn of 1887 and all of 1888 but were delivered only during the 1888 Spring semester, a complete mathematical logic program compiled by Poretsky, materials related to Poretsky's father and family, Poretsky's Magister's (master's) dissertation and the decision of the physics-mathematics faculty council to award him the doctorate in astronomy rather than the Magister, a complete list of the sources he used (including Boole, Jevons, Schroder, and Peano), biographical data and materials regarding his illness and subsequent dismissal from Kazan University.
    • Poretsky became interested in logic through Alexander V Vasiliev soon after arriving in Kazan in 1876.
    • In session 1887-1888, Poretsky lectured on mathematical logic, the first time that such a course had been given in Russia.
    • I think teaching mathematical logic is very useful ..
    • Mathematical logic is a branch of the general science of operations, and in this respect deserves attention from mathematicians.
    • The basic concepts of mathematical logic to a great extent clarifies the fundamental theorems of mathematical theory.
    • Poretsky worked on mathematical logic for the rest of his life, extending and augmenting results of George Boole, Stanley Jevons, Ernst Schroder and John Venn [Dictionary of Scientific Biography (New York 1970-1990).',1)">1]:- .
    • In papers published from 1880 to 1908, Poretsky systematically studied and solved many problems of the logic of classes and of propositions.
    • He published major works on methods of solution of logical equations, and on the reverse mode of mathematical logic.
    • He applied his logic calculus to the theory of probability.
    • He continued to undertake research into mathematical logic for the remaining eighteen years of his life.
    • Scientists in Russia and the Soviet Union made a significant contribution to the development of mathematical logic - both its classical and non-classical areas.
    • Of course, the separation of logic into "classical" and "non-classical" is quite arbitrary.
    • Thus, A N Kolmogorov left outstanding results in both the classical and the non-classical areas of modern logic.
    • But who in Russia was the pioneer of mathematical logic? ..
    • He was the first in Russia not only to be engaged in research on mathematical logic, and the first to deliver a course on mathematical logic (the Kazan University), but also achieved - thanks to his understanding of the subject and his development of original methods - word-wide visibility and recognition.

  8. Adian biography
    • And in 1957 an event happened which completely changed life for both him and his teacher, the Department of Mathematical Logic was created in the Steklov Mathematical Institute (MIAN), and Novikov was invited to lead it.
    • In 1965, at the invitation of A A Markov, Adian also took a second position, in the Department of Mathematical Logic at MSU.
    • His work there continues to ensure a close and fruitful collaboration of the department with the Department of Mathematical Logic at MIAN.
    • The Department of Mathematical Logic in the Faculty of Mechanics and Mathematics at MSU went through a similar period of turbulence, for similar reasons, when the head of the department, A A Markov, fell sick at the end of the 1970s.
    • Adian has always devoted much attention to strengthening the Department of Mathematical Logic at MIAN, to training researchers in the Department of Mathematical Logic at MSU, and to developing new connections between these two related groups.
    • His students are prominent researchers in algebra, mathematical logic, and computational complexity theory.
    • After finishing at MSU, the strongest of them transferred to positions in the Department of Mathematical Logic at MIAN, which under his leadership became one of the most prominent and respected research centres in logic.
    • In the Department of Mathematical Logic at MSU Adian has for many years led a seminar on algorithmic problems of algebra and logic, in addition to sharing leadership of the department's main seminar with V A Uspenskii.
    • Several times he has also given mandatory lecture courses in mathematical logic for the first and fourth years, and special lecture courses on algorithmic problems of algebra and on infinite periodic groups.
    • Adian is in essence the creator and leader of a whole research school in mathematical logic and algorithmic problems of algebra.
    • As long ago as the end of 1950s, S M Nikol'skii invited Adian, at the suggestion of Novikov, to edit the section on mathematical logic in Referativnyi Zhurnal: Matematika, the Russian mathematical review journal, because there was then a huge backlog of articles to be reviewed.
    • In the shortest possible time Adian rectified the situation there with respect to logic by mobilizing almost all his colleagues for the thankless task of writing reviews (for only a paltry fee).
    • At about the same time, he drew attention to the fact that a remarkable textbook on mathematical logic written by Novikov had not been published, and that undergraduate and graduate students had to read a typescript.
    • He declined Novikov's offer that he should be coauthor, and about half a year later the first edition of Novikov's textbook on mathematical logic appeared.
    • dissertations in mathematical logic, algebra, number theory, geometry, and topology, first as the vice-chairman and later, after the death of Vinogradov, as the chairman.

    • I taught Mathematical Logic and Set Theory as well as a general course of Logic in Philosophy.
    • challenged received notions of knowledge, meaning and truth, and exceeded even the extreme empiricism of logical positivism by arguing that logic and mathematics, like factual statements, are open to revision in the light of experience.
    • The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges.
    • We have commented above about Quine's work in mathematical logic.
    • Symbolic logic represented for him the framework for the language of science.
    • I do not do anything with computers, although one of my little results in mathematical logic has become a tool of the computer theory, the Quine McCluskey principle.
    • I arrived at it not from an interest in computers, but as a pedagogical device, a slick way of introducing that way of teaching mathematical logic.
    • Among Quine's publications are works on logic, metaphysics, the philosophy of language, and the philosophy of logic.
    • His 22 books include A System of Logistic (1934), Mathematical Logic (1940), Elementary Logic (1941), On What There Is (1948), From a Logical Point of View (1953), Word and Object (1960), Set Theory and Its Logic (1963), Philosophy of Logic (1970), The Time of My Life: an autobiography (1985), Quiddities (1990), and From Stimulus to Science (1995).

  10. Jevons biography
    • An important influence on Jevons while he was studying in London was De Morgan, not in terms of Jevons thoughts on economics but certainly in terms of his thoughts on logic and probability.
    • He was appointed to a second post in 1865 when he became a part-time professor of logic and political economy at Queen's College, Liverpool.
    • Then in 1866 he was appointed to a chair of political economy at Manchester and also to a professorship in logic and mental and moral philosophy.
    • He published Pure Logic in 1864, developed the 'logical piano' which was exhibited at the Royal Society in 1870, and he published The Theory of Political Economy in 1871.

    • Grattan-Guinness [Studies in the History of Statistics and Probability II (London, 1977), 180-212.',10)">10] suggests that the main difference between their approach was that, although both believed they were studying the laws of thought, Boole had a more algebraic concept of logic while Jevons argued that mathematics proceeds from logic.
    • The 'logical piano', a machine designed by Jevons and constructed by a Salford watchmaker, had 21 keys for operations in equational logic.
    • Although its principal value was as an aid to the teaching of the new logic of classes and propositions, it actually solved problems with superhuman speed and accuracy ..

    • Her work in mathematical logic became very important in the development of the subject in Soviet Union.
    • In her writings on philosophy of mathematics and philosophy of logic, she took the offensive against the idealist philosophy of the bourgeois West, represented in her mind by Gottlob Frege, and against the so-called Machism, that is, conventionalism, represented by Rudolf Carnap and his Principle of Tolerance, according to which in logic one is free to choose one's rules.
    • Janovskaja published two major studies of the history of mathematical logic in the USSR between 1917 and 1957.
    • An important aspect of Janovskaja's work was in translating into Russian and editing works of high international repute in mathematical logic.

    • His writings on the philosophy of logic, philosophy of mathematics, and philosophy of language are of major importance.
    • In effect, it constitutes perhaps the greatest single contribution to logic ever made and it was, in any event, the most important advance since Aristotle.
    • He stated in the Preface to the work that he wanted to prove the basic truths of arithmetic "by means of pure logic".
    • This aim makes Frege the first to fully develop the main thesis of logicism, that mathematics is reducible to logic.
    • Frege then went on to give his own definitions of the basic concepts of arithmetic based purely on logic, and from these he deduced, again using pure logic, the basic laws of arithmetic.
    • a series of brilliant philosophical articles in which he elaborated his philosophy of logic.
    • In the longer term, however, Frege has become a major influence on the development of philosophical logic and the man who seems to have been largely ignored by his contemporaries has been avidly read by many in the second half of the twentieth century, particularly after his works were translated into English.
    • In 1923 Frege came to the conclusion that the aim he had set himself throughout most of his career, namely to found arithmetic on logic, was wrong.
    • His revolutionary new logic was the origin of modern mathematical logic - a field of import not only to abstract mathematics, but also to computer science and philosophy.

  13. Kleene biography
    • It had been Oswald Veblen who had proposed that the development of logic required careful analysis by mathematicians.
    • It was certainly an exciting place to be undertaking research applying mathematical techniques to logic with visitors such as Kurt Godel - Kleene attended a course he gave at the Institute for Advanced Study.
    • Kleene received a doctorate from Princeton for his thesis entitled A Theory of Positive Integers in Formal Logic in 1934.
    • we shall be concerned primarily with the development of the system of logic based on a set of postulates proposed by A Church.
    • By carrying out the construction on the basis of a certain subset of Church's formal axioms, we show that this portion at least of the theory of positive integers can be deduced from logic without the use of the notions of negation, class, and description.
    • Chapter I is by far the best introduction to intuitionistic logic which is at present available for a mathematical logician.
    • Kleene's best known books are Introduction to Metamathematics (1952) and Mathematical Logic (1967).
    • The aim of this book is to provide a connected introduction to the subjects of mathematical logic and recursive functions in particular, and to the newer foundational investigations in general.
    • Since the number of such texts in the field of logic is quite small, this book by an outstanding authority in the field is especially welcome.
    • Other honours included election to the National Academy of Sciences (1969), election as President of the Association for Symbolic Logic (1956-58), president of the International Union of the History and the Philosophy of Science (1961) and of the Union's Division of Logic, Methodology and Philosophy of Science (1960-62).
    • He was editor of the Journal of Symbolic Logic for twelve years.
    • He was an avid climber and, until well into his seventies, led the biannual logic picnic at Madison (now the Kleene Memorial Logic Picnic) on hikes up the cliffs at Devil's Lake.

  14. Lesniewski biography
    • At that time Jan Lukasiewicz was teaching at Lwow, being promoted from Privatdozent to extraordinary professor in 1911, and he greatly influenced Lesniewski in the first course on mathematical logic which he gave there.
    • He began to study formal logic and began to make strenuous attempts to understand Russell's paradox which he had learnt through Lukasiewicz.
    • There he began to get more involved in the study of mathematical logic.
    • During this time Lukasiewicz and Lesniewski founded the Warsaw School of Logic.
    • From then until 1939 he published a series of twelve papers giving his theories of logic and mathematics.
    • These lectures are given in [Lesniewski\'s lecture notes in logic (Dordrecht, 1988).',5)">5].
    • ',15)">15] argues that the importance of Lesniewski's work is in providing an alternative to the classical approach to logic and the foundations of mathematics.
    • Lesniewski's contributions to logic concentrate on the structure of a sentence, and he argues for the traditional idea of a sentence as consisting of a subject, an object and a copula.
    • The three major logical systems which Lesniewski developed were: Protothetic, a theory of propositions and propositional functors, similar in power to a theory of propositional types, providing an extended propositional calculus with quantified functional variables; Ontology, which is an axiomatised theory of common names based on protothetic which may be characterised as a cross between traditional term logic and modern type theory, containing, besides singular terms, also empty and plural terms and a host of other interesting features; and Mereology, which is an axiomatic extension of ontology for a theory of classes quite different from set theory providing a formal theory of part and whole similar to the calculus of individuals.
    • Stanislaw Lesniewski was one of the co-founders of the Polish School of Logic and an author of a new and wholly original system of the foundations of logic and mathematics.
    • He was also the forerunner and originator of many ideas included as a matter of course in modern textbooks of logic and the foundations of mathematics.
    • Although Lesniewski played a considerable role during the period of development of modern mathematical logic and of the foundations of mathematics, his systems are not as well known as they deserve to be and the fact remains that his systems are not generally accepted as a tool in the foundational practice.

  15. Russell biography
    • Bertrand Russell published a large number of books on logic, the theory of knowledge, and many other topics.
    • Over a long and varied career, Bertrand Russell made ground-breaking contributions to the foundations of mathematics and to the development of contemporary formal logic, as well as to analytic philosophy.
    • His contributions relating to mathematics include his discovery of Russell's paradox, his defence of logicism (the view that mathematics is, in some significant sense, reducible to formal logic), his introduction of the theory of types, and his refining and popularizing of the first-order predicate calculus.
    • The significance of the paradox follows since, in classical logic, all sentences are entailed by a contradiction.
    • In the eyes of many mathematicians (including David Hilbert and Luitzen Brouwer) it therefore appeared that no proof could be trusted once it was discovered that the logic apparently underlying all of mathematics was contradictory.
    • A large amount of work throughout the early part of this century in logic, set theory, and the philosophy and foundations of mathematics was thus prompted.
    • Although first introduced by Russell in 1903 in the Principles, his theory of types finds its mature expression in his 1908 article Mathematical Logic as Based on the Theory of Types and in the monumental work he co-authored with Alfred North Whitehead, Principia Mathematica (1910, 1912, 1913).
    • Of equal significance during this same period was Russell's defence of logicism, the theory that mathematics was in some important sense reducible to logic.
    • The first is that all mathematical truths can be translated into logical truths or, in other words, that the vocabulary of mathematics constitutes a proper subset of that of logic.
    • The second is that all mathematical proofs can be recast as logical proofs or, in other words, that the theorems of mathematics constitute a proper subset of those of logic.
    • In much the same way that Russell wanted to use logic to clarify issues in the foundations of mathematics, he also wanted to use logic to clarify issues in philosophy.
    • As one of the founders of "analytic philosophy", Russell is remembered for his work using first-order logic to show how a broad range of denoting phrases could be recast in terms of predicates and quantified variables.

  16. Tichy biography
    • He remained at the Charles University, being appointed a lecturer in the Department of Logic in 1961.
    • His first book Logic for Students of Pedagogical Institutes (Czech) was published in the following year.
    • In 1993 he was offered the position of Head of the Department of Logic at the Faculty of Philosophy and Arts in the Charles University of Prague.
    • Perhaps his most important work was the book The foundations of Frege's logic (1988).
    • This book is not an introduction to Frege's general philosophy, or a running commentary on Frege's work, or a polemic against recent commentators on Frege, or an attempt to give Frege a place in the history of logic and philosophy.
    • As a result, the author discusses a wide range of living philosophical issues in the latter half of his book: Church's logic of sense and denotation, Montague's intensional logic, Gentzen's sequent calculus, and Hilbert's formal axiomatics, to name a few.
    • Perhaps his most enduring claim to fame lies in his theory called Transparent Intensional Logic, the culmination of his extensive work on semantics and logic.
    • On the cover of [Pavel Tichy\'s Collected Papers in Logic and Philosophy (Otago-Praha, Otago UP, Filosofia, 2004).',1)">1], Pavel Tichy's Collected Papers in Logic and Philosophy, this appreciation of Tichy's work is given:- .
    • He developed what he called Transparent Intensional Logic, a semantic theory within which to analyse both natural and artificial languages.
    • The theory remains one of the most inspiring and controversial doctrines of contemporary philosophical logic, attracting passionate defenders and equally fierce opponents.

  17. Sleszynski biography
    • The year 1909 was significant in another way, for it was the one in which he published his translation of Louis Couturat's famous book The algebra of logic.
    • This text had a major influence on the development of mathematical logic in Russia since it became the main textbook used by students of the subject over many years.
    • In 1919 he was promoted from extraordinary professor to become the full Professor of Logic and Mathematics the Jagellonian University.
    • Sleszynski's main work was on continued fractions, least squares and axiomatic proof theory based on mathematical logic.
    • 56 (1955-1956), 217-240.',2)">2] Bednarowski discusses Sleszynski's book O Logice Tradycyjnej (On traditional logic) published in Krakow in 1921:- .
    • Sleszynski assumes that the part of traditional logic created by Aristotle is a theory of relations which may hold between two classes.
    • We should mention another interesting work by Sleszynski, namely On the significance of logic for mathematics (Polish) published in 1923.
    • McCall writes in [Polish Logic, 1920-1939: Papers by Ajdukiewicz Andothers (Oxford University Press US, 1967).',1)">1]:- .
    • Much indeed can be learned from the rich collection of [Sleszynski's] papers on various subjects in the realm of formal logic, and of mathematical logic and its history ..
    • Introduction to mathematical logic, complete proof, mathematical proof, exposition of the theory of propositions, the Boolean calculus, Grassmann's logic, Schroder's algebra, Poretsky's seven laws, Peano's doctrine, Burali-Forti's doctrine - these are some of the themes pursued in this work, from which I personally have learned a great deal and thanks to which I have got a clear idea of many an unclear thing.

  18. MacColl biography
    • This move seems to have been well thought out for, not only was Boulogne a prosperous town with much to offer the well-educated, it also had the advantage of having close links with England so MacColl could in many ways have the best of both worlds [History and Philosophy of Logic 22 (2) (2001), 81-98.',2)">2]:- .
    • In 1883 he wrote to C S Peirce saying something about his financial problems (see [History and Philosophy of Logic 22 (2) (2001), 81-98.',2)">2]):- .
    • HUGH M'COLL, BA (LONDON UNIVERSITY) Gives Lessons in MATHEMATICS, CLASSICS, ENGLISH, LOGIC, with all the other subjects of the University Course, and prepares Young Gentlemen for the Naval and military Examinations.
    • Most of MacColl's original contributions to mathematics and logic were through papers, discussions and books after he moved to France.
    • He wrote to Bertrand Russell in 1905 about this work (see for example [History and Philosophy of Logic 22 (2) (2001), 81-98.',2)">2]):- .
    • This I thought would be my final contribution to logic or mathematics, ..
    • He published a series of nine papers entitled Symbolic Logic in The Athenaeum between 1903 and 1904, and a series of eight articles Symbolic Reasoning in Mind between 1880 and 1906.
    • His most famous book, however, was Symbolic Logic and Its Applications (1906).
    • For reaching those who do not follow closely the development of symbolic logic, publication in book form is almost essential; and it is much to be hoped that this book will be widely read.
    • The present work is not quite in line with those of other current writers on symbolic logic; but it has merits which most of their work do not have, and it serves in any case to prevent the subject from getting into a groove.
    • MacColl has other interests outside mathematics and logic.
    • He also wrote Man's Origin, Destiny and Duty (1909) in which he discusses his [Nordic Journal of Philosophical Logic 3 (1), 175-196.',4)">4]:- .

  19. Moisil biography
    • Algebra was not the only new research topic for Moisil during these years, for he became interested in logic after reading a paper by Jan Lukasiewicz.
    • It was a period in which he alternated his old interests in continuous mathematics with applications to mechanics and physics with his new interests in discrete mathematics, mainly in algebra and logic.
    • His first paper on algebra and logic was Recherches sur l'algebra de la logique (1935).
    • By non-chrysippian logic he means multivalued logic (non-aristotelian).
    • Moisil feels that the strictest standpoint in classical (formal) logic is represented by Chrysippus rather than Aristotle.
    • goal was to algebrize Lukasiewicz's logic.
    • Boolean algebras, algebraic models of classical logic, are particular cases of the new structures.
    • Moisil invented L-M algebras in order to create an algebraic structure playing the same role with respect to multiple-valued logic as Boolean algebras play with respect to classical, bivalent logic.
    • Extensive use is also made of n-valued logic.
    • Rings and ideals (Romanian) (1954); Time sequential operation of circuits with ideal relays (Romanian) (1960); Essays old and new on non-classical logic (Romanian) (1965); Algebraic theory of schemes with contacts and relays (Romanian) (1965); and Actual functioning of relay switching circuits.

  20. Smullyan biography
    • He wanted to learn about groups, rings and fields, the foundations of mathematics and mathematical logic.
    • Returning to New York from San Francisco, Smullyan studied mathematics and logic on his own and it was at this time that he began to compose chess puzzles.
    • Smullyan published Languages in which self reference is possible in the Journal of Symbolic Logic in 1957.
    • Smullyan's publications have been quite remarkable with the two outstanding books on retrograde analysis chess problems [The Chess Mysteries of the Sherlock Holmes (New York, 1979).',2)">2] and [The Chess Mysteries of the Arabian Knights (New York, 1981).',3)">3], a whole series of marvellous popular puzzle books such as [What is the name of this book? (New York, 1978).',1)">1] and [Satan, Cantor, and Infinity and other mind-boggling puzzles (New York, 1992).',4)">4], and some books on the foundations of mathematics and mathematical logic which are in many ways in a class of their own.
    • Beginning with fun-filled monkey tricks and classic brain-teasers with devilish new twists, Professor Smullyan spins a logical labyrinth of even more complex and challenging problems as he delves into some of the deepest paradoxes of logic and set theory, including Godel's revolutionary theorem of undecidability.
    • The most original, most profound and most humorous collection of recreational logic and mathematics problems ever written.
    • We have mentioned one of his books on mathematical logic above.
    • He published another text First-order logic in 1968:- .
    • This book deals primarily with the proofs of, and the interconnections between, various formulations of the completeness theorem for first-order logic.
    • for the general mathematician, philosopher, computer scientist and any other curious reader who has at least a nodding acquaintance with the symbolism of first-order logic, and who can recognize the logical validity of a few elementary formulas.
    • A standard one-semester course in mathematical logic is more than enough for the understanding of this volume.
    • I watched him teach a graduate level logic course, as he lurched to the blackboard (where he writes in a serviceable hand and in complete sentences) and paced about his desk, fidgeting and chuckling.

  21. Padoa biography
    • (Before Padoa became a teacher at the High School "Cristoforo Colombo" in Genoa, Vitali had taught there from 1904 to 1923.) In 1932 Padoa was appointed as a lecturer in Mathematical Logic at the University of Genoa and he held this post until 1936 when he reached the age limit for lecturers and was forced to retire.
    • This was certainly not the first time that Padoa had attempted to leave school teaching and become a university lecturer; he had applied unsuccessfully for a lectureship in Mathematical Logic in 1901, a lectureship in Descriptive Geometry in 1909, and a lectureship in Theoretical Philosophy in 1912.
    • After he was appointed at the staff of the University of Genoa, he taught courses on 'Mathematical Logic' (1932-34), 'Ideographic Logic' (1934-37), and 'Descriptive Geometry' (1935-36).
    • He belonged to Peano's school of mathematical logic, popularising this type of work.
    • Various scientists from all countries who have adopted the ideographic logic believe that it is refined and completed today.
    • Continuing his work as a collaborator and adviser, M Padoa has led everyone to appreciate the simplicity and power of the ideographic language - which has given birth to a new development in deductive logic and a further analysis of the different branches of mathematics - and to consult profitably and easily the many books in which it is applied.
    • This admirable exposition of the mathematical logic of Peano and his school was given in the form of lectures delivered under the auspices of the University of Geneva, and was published in the 'Revue de Metaphysique et de Morale' for 1912.
    • Cooper Harold Langford writes [The Journal of Symbolic Logic 2 (1) (1937), 57.',8)">8]:- .
    • Logic, Padoa says, is not in a particularly fortunate position.
    • The paper contains an outline of the fundamental ideas introduced into logic by Peano, together with examples illustrating how the distinctions Peano drew remove confusions and paradoxes.

  22. Davis biography
    • Davis took a course on symbolic mathematical logic in his first year and a reading course on real variable theory with Emil Post in his second year.
    • In his third year he began taking a reading course with Post on mathematical logic but this stopped when Post had a breakdown.
    • in 1948 he knew he wanted to undertake research in mathematical logic.
    • He had already written a report as part of an advanced logic course he had taken in his final year and this was later incorporated into his Ph.D.
    • There he taught a logic course which had computability as one of the main topics.
    • The 1958 paper with Hilary Putnam was the result of their families sharing a house while at a five-week logic conference at Cornell in the summer of 1957.
    • Symbolic Logic 3 (4) (1958), 432-433.',12)">12]:- .

    • Cohen, through these friendships, had also begun to take an interest in logic [Bull.
    • Symbolic Logic 15 (4) (2009), 439-440.',14)">14]:- .
    • As a graduate student Cohen's connection with logic were his friendships with a lively group of students who became logicians; Michael Morley, Anil Nerode, Bill Howard, Ray Smullyan, and Stanley Tennenbaum.
    • For a while he lived in Tennenbaum's house and absorbed logic by osmosis, for there were no courses in logic in the Chicago mathematics department.
    • A dramatic aspect of the continuum hypothesis work is that Cohen was a self-taught outsider in logic.
    • In addition it presents also the main classical results in logic and set theory.
    • For epoch-making results in mathematical logic which have enlivened and broadened investigations in the foundation of mathematics.
    • Like many great mathematicians, his mathematical interests and contributions were very broad, ranging from mathematical analysis and differential equations to mathematical logic and number theory.

  24. Mostowski biography
    • He entered Warsaw University after graduating from the Stefan Batory Gymnasium and it was at this time that he became especially interested in the foundations of mathematics, particularly mathematical logic and set theory.
    • was awarded in February 1939 for his thesis On the Independence of Finitenesss Definitions in a System of Logic, officially directed by Kuratowski but in practice directed by Tarski who was a young lecturer at that time.
    • Mostowski wrote an important Polish text Mathematical Logic which was published in 1948.
    • This is an exceptionally good handbook of mathematical logic.
    • It covers a great deal of material and shows many applications of mathematical logic to mathematical problems ..
    • The author is eager to persuade a mathematician that logic can be useful in his work.
    • The symbolism of mathematical logic is used throughout, but with moderation, and ample motivation is given in the text appealing to the intuition on the infinite sets.
    • Lectures on the development of mathematical logic and the study of the foundations of mathematics in 1930-1964 which reports on a 16 lecture course given by Mostowski in the summer of 1964 in Vaasa, Finland, gives the best view of what he saw as the most important developments in his subject during his career.
    • The topics include completeness, incompleteness, decidability, and undecidability theorems; computability, recursive functions, hierarchies, and functionals; intuitionistic logic and its interpretations; constructive mathematics, foundations of set theory, including Cohen's independence proofs; and finally model theory, ending in a special chapter on direct and reduced products.
    • He was the editor of the Mathematical, Astronomical and Physical series of the Bulletin of the Polish Academy of Sciences, on the editorial board of several journals including Fundamenta Mathematicae, Dissertationes Mathematicae, the Journal of Symbolic Logic and Studia Logica.
    • He was one of the founders and editors of the Annals of Mathematical Logic.

  25. Skolem biography
    • His dissertation Undersokelser innenfor logikkens algebra (Investigations on the Algebra of Logic) was considered so outstanding that his achievement was reported to the King of Norway.
    • [Skolem] conducted the regular graduate courses in algebra and number theory, and rather infrequently lectured on mathematical logic.
    • Skolem was remarkably productive publishing around 180 papers on topics such as Diophantine equations, mathematical logic, group theory, lattice theory and set theory.
    • However, as Fenstadt explains in [Thoralf Skolem, Selected works in logic (Oslo, 1970).',2)">2]:- .
    • Logic 1 (2) (1996), 107-117.',9)">9], sees Skolem as being a pioneer in computer science:- .

  26. Kuroda biography
    • In many ways Kuroda's work on the foundations of mathematics and mathematical logic had made it difficult for him to become a central figure in Japanese mathematics.
    • Over the following years he published papers such as Intuition and consistency in mathematics (Japanese) (1947), On the logic of Aristotle and the logic of Brouwer (Japanese) (1948), and Intuitionistische Untersuchungen der formalistischen Logik (1951).
    • Symbolic Logic 21 (2) (1956), 196.',3)">3]:- .
    • illustrates intuitionistic points of view towards mathematics, and investigates intuitionistic logic as formalized by Heyting-Gentzen.
    • In fact he makes it clear in the 1951 paper that he shares L E J Brouwer's view that mathematics is an activity of thought that is independent of logic and based on immediate evidence that is intuitively clear.
    • Therefore, in formulating these systems, some special conditions to restrict the free application of logic are needed, for instance, simple or ramified type theory, introduced to logic first by Russell, or the restriction of the comprehension axiom of set theory.
    • Despite his many deep works on mathematical logic and the foundations of mathematics, Kuroda had a lifelong interest in algebraic number theory.

  27. Ockham biography
    • Peter Lombard, a conservative theologian, wrote the text as a reaction against some who at the time were applying Aristotle's logic to theology.
    • Ockham lectured on logic and natural philosophy in a Franciscan school from 1321 to 1324 while he waited to return to university to study for his doctorate.
    • During these years he wrote many deep works on philosophy and logic.
    • The logic was clear to Ockham; Pope John XXII was no true pope and he denounced him with written charges.
    • Ockham had convinced other leading Franciscans of the logic of his arguments, and together they fled to Pisa on 26 May 1328.
    • One might argue that it was a pity that he became distracted from his work on philosophy and logic during these latter years.
    • In his studies of mathematical logic Ockham made important contributions to it which are significant today.
    • He considered a three valued logic where propositions can take one of three truth values.
    • And from the standpoint of the philosophy of the 1980s and 1990s, Ockham's interest in terminist logic, linguistic theory, and semiotics has placed him in the forefront of those medieval thinkers used as sources in contemporary philosophical discussion.

  28. Peano biography
    • In 1888 Peano published the book Geometrical Calculus which begins with a chapter on mathematical logic.
    • at once a landmark in the history of mathematical logic and of the foundations of mathematics.
    • In 1891 Peano founded Rivista di matematica, a journal devoted mainly to logic and the foundations of mathematics.
    • The first paper in the first part is a ten page article by Peano summarising his work on mathematical logic up to that time.
    • Of course it was the precision of his thinking, using the exactness of his mathematical logic, that gave Peano this clarity of thought.
    • Such a collection, which would be long and difficult in ordinary language, is made noticeably easier by using the notation of mathematical logic ..
    • As the days went by, I decided that this must be owing to his mathematical logic.
    • Although Peano is a founder of mathematical logic, the German mathematical philosopher Gottlob Frege is today considered the father of mathematical logic.

  29. Lob biography
    • It seems an unlikely palace for Lob to be able to study mathematics and logic at an advanced level, but one must remember that professional mathematicians were also interned in the camp and were keen to teach.
    • He remained at Leeds for 20 years being promoted to Reader, then to Professor of Mathematical Logic.
    • At Leeds Lob established the Leeds Logic Group, one of three international centres for Mathematical Logic in Britain.
    • Examples of papers by Lob in the Journal of Symbolic Logic in the 1950s are Concatenation as basis for a complete system of arithmetic (1953), Solution of a problem of Leon Henkin (1955), and Formal systems of constructive mathematics (1956).
    • Examples of papers he published in the 1970s are A model theoretic characterization of effective operations (1970), Hierarchies of number-theoretic functions (1970), A reduction theorem for predicate logic (1972) and Embedding first order predicate logic in fragments of intuitionistic logic (1976).

  30. Venn biography
    • In 1862 he returned to Cambridge University as a lecturer in Moral Science, studying and teaching logic and probability theory.
    • He had already become interested logic, philosophy and metaphysics, reading the treatises of De Morgan, Boole, John Austin, and John Stuart Mill.
    • Venn extended Boole's mathematical logic and is best known to mathematicians and logicians for his diagrammatic way of representing sets, and their unions and intersections.
    • Venn wrote Logic of Chance in 1866 which Keynes described as:- .
    • Venn published Symbolic Logic in 1881 and The Principles of Empirical Logic in 1889.
    • probably his most enduring work on logic.
    • Venn's interest turned towards history and he signalled this change in direction by donating his large collection of books on logic to the Cambridge University Library in 1888.

  31. Hay biography
    • believed in teaching the logic of the subject rather than just following the theorem-proof format of the text (which of course was straight out of Euclid).
    • In fact the constraints were more severe than this, for ever since her teacher Rosenbaum had turned her on to mathematical logic, she had wanted to undertake research in that topic.
    • It was even harder to find a university with strong graduate schools in both experimental psychology and mathematical logic.
    • course she had started, but no university within travelling distance offered mathematical logic at doctoral level.
    • She published papers on mathematical logic, recursive function theory, and theoretical computer science.
    • She published Axiomatization of the infinite-valued predicate calculus in the Journal of Symbolic Logic in 1963 in which she gave a set of nine axiom schemes and two rules for the predicate calculus based on the infinite-valued sentential calculus of Lukasiewicz.
    • While Louise Hay was widely recognized for her contributions to mathematical logic and for her strong leadership as head of the Department of Mathematics, Statistics, and Computer Science at the University of Illinois at Chicago, her devotion to students and her lifelong commitment to nurturing the talent of young women and men secure her reputation as a consummate educator.

  32. Lyndon biography
    • He began working on mathematical logic, moved to a study of relational algebras, then finally undertook research in homological algebra.
    • Combinatorial group theory was not Lyndon's first book, however, for he had published Notes on logic ten years earlier in 1966.
    • The book contains a concise and clear exposition of basic notions of mathematical logic.
    • More specifically, the author deals with the first-order logic with symbols for relations and functions.
    • As should be clear from this description, the book is intended as a text to enable a mathematically well-trained reader to acquaint himself quickly with the basic results of logic.
    • In the reviewer's opinion the book has set a new standard for texts in mathematical logic which will not be easy to supersede.
    • They include: Groups rings and dimension subgroups; Two investigations on the borderline of logic and algebra; Decision problems of finite automata design and related arithmetic; On Dehn's algorithm and the conjugacy problem; Projectivities of free products; Continuous model theory and set theory; Real length functions in groups; Automorphisms of the fundamental group of an orientable 2-manifold; Some algorithmic problems for semigroups; and Groups acting on trees.

  33. Aristotle biography
    • Aristotle was not primarily a mathematician but made important contributions by systematising deductive logic.
    • According to a tradition which arose about two hundred and fifty years after his death, which then became dominant and even today is hardly disputed, Aristotle in these same years lectured - not once, but two or three times, in almost every subject - on logic, physics, astronomy, meteorology, zoology, metaphysics, theology, psychology, politics, economics, ethics, rhetoric, poetics; and that he wrote down these lectures, expanding them and amending them several times, until they reached the stage in which we read them.
    • What do these works contain? There are important works on logic.
    • Aristotle believed that logic was not a science but rather had to be treated before the study of every branch of knowledge.
    • Aristotle's name for logic was "analytics", the term logic being introduced by Xenocrates working at the Academy.
    • Aristotle believed that logic must be applied to the sciences [Aristotle (Oxford, 1982).',6)">6]:- .

    • Chrysippus was one of the first to organise propositional logic as an intellectual discipline.
    • Diogenes Laertius in [Lives of eminent philosophers (New York, 1925).',3)">3] lists 118 works on logic by Chrysippus, and of these 118 there are seven books occupying 15 rolls of papyri concerning the Liar Paradox.
    • One claim which Chrysippus made in the area of logic was to reject that the impossible does not follow from the possible.
    • Logic 13 (2) (1992), 133-148.',8)">8] which also examines more generally his views on modal logic.
    • He believed that logic and physics are necessary to differentiate between good and evil.
    • To him the value of physics and logic is mainly for this purpose.

  35. Jungius biography
    • where he commented on the Dialectic of Peter Ramus, as well as writing on logic and composing poetry.
    • In general, however, he preferred to concentrate on mathematics and logic.
    • The Logica Hamburgensis (1638) of Jungius, composed for the use of pupils at the Akademisches Gymnasium, presented late medieval theories and techniques of logic.
    • Joachim Jungius was a German polymath somewhat in the Leibnizian tradition of encyclopaedic range as well as originality in several domains of knowledge, including logic, mathematics, and natural philosophy.
    • shifted: from his early training in the late scholasticism of Francisco Suarez and his like, to astronomy, logic and mathematics, educational reform, medicine, and chemical philosophy (in his case corpuscularism), to an ambitious program to organise, systematise, and taxonomise - as well as further to contribute to (based on a mathematical paradigm) - the sum total of human knowledge.
    • Kangro's most fortunate discovery, in his own estimation, was a fragment that reflects Jungius' fundamental ideas on logic applied to science.
    • These three methods replaced the prevalent ancient form of logic based on the syllogism.

  36. Peirce Charles biography
    • By the age of twelve Charles was reading standard university level texts on logic, and in the following year he began reading Immanuel Kant's Critique of Pure Reason.
    • He gave the Harvard lectures on The Logic of Science in the spring of 1865 and the Lowell Institute lectures on The Logic of Science; or Induction and Hypothesis in the latter part of 1866.

    • In 1854 he published An investigation into the Laws of Thought, on Which are founded the Mathematical Theories of Logic and Probabilities.
    • Boole approached logic in a new way reducing it to a simple algebra, incorporating logic into mathematics.
    • It began the algebra of logic called Boolean algebra which now finds application in computer construction, switching circuits etc.
    • I am now about to set seriously to work upon preparing for the press an account of my theory of Logic and Probabilities which in its present state I look upon as the most valuable if not the only valuable contribution that I have made or am likely to make to Science and the thing by which I would desire if at all to be remembered hereafter ..
    • Boole's system of logic is but one of many proofs of genius and patience combined.
    • That the symbolic processes of algebra, invented as tools of numerical calculation, should be competent to express every act of thought, and to furnish the grammar and dictionary of an all-containing system of logic, would not have been believed until it was proved.

  38. Herbrand biography
    • He had already set himself the goal of creating a school of mathematical logic in France to rival that in Gottingen.
    • For his doctoral thesis he studied mathematical logic under the supervision of Ernest Vessiot who at that time was the Director of the Ecole Normale.
    • On the one hand mathematical logic was a surprising choice, given the lack of interest in that topic in France in this period.
    • Vessiot played an important role here, convincing analysts somewhat sceptical about the importance of mathematical logic.
    • He made contributions to mathematical logic where Herbrand's theorem on the theory of quantifiers appears in his doctoral thesis.
    • Herbrand's theorem establishes a link between quantification theory and sentential logic which is important in that it gives a method to test a formula in quantification theory by successively testing formulas for sentential validity.
    • Thus, the lifelong interest he had in mathematical logic was perhaps born of the wondrous hope of anticipating the future by means of finite calculi and combinations.

  39. Post biography
    • While studying at the College of the City of New York he studied mathematics but there is little sign that at this stage he was particularly attracted towards logic.
    • thesis was on mathematical logic, and we shall discuss it further in a moment, but first let us note that Post wrote a second paper as a postgraduate, which was published before his first paper, and this was a short work on the functional equation of the gamma function.
    • The final, and perhaps the most remarkable, new idea which Post introduced in his thesis was to give a framework for systems of logic as inference systems based on a finite process of manipulation of symbols.
    • Such a system of logic that Post proposed produces, in today's terminology, a recursively enumerable set of words on a finite alphabet.
    • it is fundamentally weak in its reliance on the logic of Principia Mathematica ..

    • Her main research was in algebraic logic and the mathematical foundations of computer science.
    • In algebraic logic she continued work by Post, Stone, Tarski and Lukasiewicz [Bull.
    • Of course Rasiowa's work on algebraic logic was in precisely the right area to make her a natural contributor to theoretical computer science.
    • Her contribution to theoretical computer science stems from her conviction that there are deep relations between methods of algebra and logic on the one side and essential problems of foundations of computer science on the other.
    • It was partly through her endeavours that the Polish Society for Logic and the Philosophy of Science was set up.

  41. Kalicki biography

    • The next paper in the same part of the Journal of Symbolic Logic is also by Kalicki.
    • Two years later another paper by Kalicki in the Journal of Symbolic Logic is A test for the equality of truth-tables which gives a necessary and sufficient condition for the equivalence of two truth-tables.

    • During this period at Cambridge, Wittgenstein continued to work on the foundations of mathematics and also on mathematical logic.
    • Despite Russell's attempts to stop him, Wittgenstein went to Skjolden in Norway and this proved an extremely fruitful period during which lived in isolation working on his ideas on logic and language that would form the basis of his great work the Tractatus Logico-Philosophicus.
    • During these four years of active service Wittgenstein had written his great work in logic, the Tractatus, and the manuscript was found in his rucksack when he was taken prisoner.

    • Robinson is best known, however, for his work on mathematical logic.
    • He was deeply concerned with most forms of human culture and creativity, and on all he could converse with the fascinating combination of logic, insight and knowledge that characterised his mathematics.
    • When one considers the wealth, profundity and diversity of his interests and the continuous interplay in his thinking of pure mathematics, applied mathematics, logic and philosophy one is constantly reminded of Leibniz to whom he felt a natural affinity and for whom he had the deepest admiration.
    • Today I should like to offer a partial answer: It cannot be a wholly bad worlds in which an Abraham Robinson could live and think; in which his wife and friends are able to cherish his memory; and in which his life's work will be remembered as long as logic, mathematics and philosophy matter to mankind.

    • As a matter of logic this is a commonplace.
    • The distinction between deductive logic and scientific inference may be illustrated by means of one of the classical instances of the former.
    • This type of argument, the syllogism, is one of those chiefly used in pure logic; indeed it was believed for ages that there was no other.
    • The notion of probability, which plays no part in logic, is fundamental in scientific inference.

  2. Poincaré on intuition in mathematics
    • Henri Poincare published Intuition and Logic in mathematics as part of La valeur de la science in 1905.
    • Intuition and Logic in Mathematics .
    • The one sort are above all preoccupied with logic; to read their works, one is tempted to believe they have advanced only step by step, after the manner of a Vauban who pushes on his trenches against the place besieged, leaving nothing to chance.
    • And yet nature is always the same; it is hardly probable that it has begun in this century to create minds devoted to logic.
    • Nothing is more shocking to intuition than this proposition which is imposed upon us by logic.
    • Pure logic could never lead us to anything but tautologies; it could create nothing new; not from it alone can any science issue.
    • In one sense these philosophers are right; to make arithmetic, as to make geometry, or to make any science, something else than pure logic is necessary.
    • All four are attributed to intuition, and yet the first is the enunciation of one of the rules of formal logic; the second is a real synthetic a priori judgment, it is the foundation of rigorous mathematical induction; the third is an appeal to the imagination; the fourth is a disguised definition.
    • This shows us that logic is not enough; that the science of demonstration is not all science and that intuition must retain its role as complement, I was about to say, as counterpoise or as antidote of logic.
    • Can logic give it to us? No; the name mathematicians give it would suffice to prove this.
    • In mathematics logic is called analysis and analysis means division, dissection.
    • Thus logic and intuition have each their necessary role.
    • Logic, which alone can give certainty, is the instrument of demonstration; intuition is the instrument of invention.
    • And first do you think these logicians have always proceeded from the general to the particular, as the rules of formal logic would seem to require of them? Not thus could they have extended the boundaries of science; scientific conquest is to be made only by generalization.
    • Is there room for a new distinction, for distinguishing among the analysts those who above all use this pure intuition and those who are first of all preoccupied with formal logic? .

  3. A N Whitehead addresses the British Association in 1916, Part 2
    • It will be necessary to sketch in broad outline some relevant features of modern logic.
    • In doing so I shall try to avoid the profound general discussions and the minute technical classifications which occupy the main part of traditional logic.
    • It is characteristic of a science in its earlier stages - and logic has become fossilised in such a stage - to be both ambitiously profound in its aims and trivial in its handling of details.
    • The next section of logic is the algebraic stage.
    • The theory of the interconnection between the truth-values of the general propositions arising from any such aggregate of propositional functions forms a simple and elegant chapter of mathematical logic.
    • In this algebraic section of logic the theory of types crops up, as we have already noted.
    • The final impulse to modern logic comes from the independent discovery of the importance of the logical variable by Frege and Peano.
    • The essence of the process is, first to construct the notion in terms of the forms of propositions, that is, in terms of the relevant propositional functions, and secondly to prove the fundamental truths which hold about the notion by reference to the results obtained in the algebraic section of logic.
    • A more important question is the relation of induction, based on observation, to deductive logic.
    • I will now break off the exposition of the function of logic in connection with the science of natural phenomena.
    • Logic, properly used, does not shackle thought.
    • Also the mind untrained in that part of constructive logic which is relevant to the subject in hand will be ignorant of the sort of conclusions which follow from various sorts of assumptions, and will be correspondingly dull in divining the inductive laws.
    • The fundamental training in this relevant logic is, undoubtedly, to ponder with an active mind over the known facts of the case, directly observed.
    • Neither logic without observation, nor observation without logic, can move one step in the formation of science.
    • Logic is the olive branch from the old to the young, the wand which in the hands of youth has the magic property of creating science.

  4. C Chevalley on Herbrand's thought

  5. R L Wilder: 'Cultural Basis of Mathematics II
    • I wonder what he would do about logic, however? .
    • In the index of Ball's first edition (1888) there is no mention of "logic;" but in the fourth edition (1908) "symbolic and mathematical logic" is mentioned with a single citation, which proved to be a reference to an incidental remark about George Boole to the effect that he "was one of the creators of symbolic or mathematical logic." Thus symbolic logic barely squeezed under the line because Boole was a mathematician! The index of Cajori's first edition (1893) contains four citations under "logic," all referring to incidental remarks in the text.
    • None of these citations is repeated in the second edition (1919), whose index has only three citations under "logic" (two of which also constitute the sole citations under "symbolic logic"), again referring only to brief remarks in the text.
    • Inspection of the text, however, reveals nearly four pages (407-410) of material under the title "Mathematical logic," although there is no citation to this subject in the index nor is it cited under "logic" or "symbolic logic." (It is as though the subject had, by 1919, achieved enough importance for inclusion as textual material in a history of mathematics although not for citation in the index!) .
    • Turning to the index of this book, I found so many citations to "logic" that I did not care to count them.
    • In particular, Bell devotes at least 25 pages to the development of what he calls "mathematical logic." Can there be any possible doubt that this subject, not considered part of mathematics in our culture in 1900, despite the pioneering work of Peano and his colleagues, is now in such "good standing" that any impartial definition of mathematics must be broad enough to include it? .

    • Though devoid of any symbolic logic, its subject matter and quality are such as to make it vital to readers of this Journal.
    • The Journal of Symbolic Logic 28 (2) (1963), 168-169.
    • The authors employ a balanced blend of formal and informal methods of presentation, symbolic logic being introduced mainly in the statement of axioms and definitions, to ensure accuracy.
    • The Journal of Symbolic Logic 29 (3) (1964), 141.
    • Of all the many branches of mathematics, set theory has the closest links with logic and philosophy.
    • Accordingly, an author who attempts to give an adequate discussion of the foundations of set theory is confronted with a formidable task, for he must not only describe the purely technical aspects of the subject, but must also elucidate the role that logic and philosophy have played in its development.
    • The purpose of this book is not to present in a systematic way, a more or less extended part of set theory, but to present to readers without special mathematical training, problems at the borders of set theory and logic - like those of mathematical infinity or the set theory paradoxes.
    • Set Theory and logic (1966), by A A Fraenkel.
    • The word "logic" in the title indicates only that some attention is devoted to definitions and methods of proof.
    • There is no discussion of mathematical logic or of any technical logical problems.
    • The Journal of Symbolic Logic 34 (1) (1969), 112-113.
    • The book is designed to provide an easy introduction to the problem of infinity and a treatment of logical problems arising at several critical points in set theory for college freshmen in mathematics, logic, and philosophy.
    • The book concludes with remarks on the scope and applications of set theory, describing set theory as "a cornerstone in the foundations of many other branches of mathematics and the chief connecting link between mathematics and logic." The book is lucid and stimulating and should for the most part be rewarding reading for its intended audience.

  7. C Chevalley: 'On Herbrand's thought
    • In June 1934 Claude Chevalley gave a lecture On Herbrand's thought at the Colloquium on Mathematical Logic which had been organised at the University of Geneva.
    • In 1928, he took first place in the Agregation, and was able to stay a fourth year at the Ecole, during which he completed his thesis, which contains the work in mathematical logic that he had been pursuing for two years.
    • He spent the academic year 1930-1931 in Germany: first in Berlin with von Neumann, where he continued his work in logic, notably comparing his results to those of Godel; then he went to Hamburg and finally to Gottingen.
    • Jacques Herbrand expressed himself rather little on the philosophical ideas relating to the problems of mathematical logic (see, however, the Introduction to his thesis).
    • The same considerations apply to logic.
    • Logic comprises a schema which is objective only insofar as it is purely formal.
    • Were one to give a sense to the symbols appearing in the formulas of logic, were one to consider them as representing operations of thought, one could cause logic to lose its objectivity.
    • This is why it is not surprising that different thinkers have different opinions on the value of the axioms of logic.
    • If the system of forms of classical logic is repugnant to Brouwer's thought, for example, this does not mean that this logic is denuded of value; it is an assertion about Brouwer's thought.
    • But in any case a human thought remains incongruous in any formalism; there is the same relationship between a formal logic and a mode of thought as between a mathematical equation and a physical phenomenon.
    • Just as mathematical physics permits us to penetrate further and further into the structure of matter, logic allows us to describe something nearer yet to man than his sensations: his intellectual thought.
    • This is the greatest demand one could make on a formal logic: it leads us to the very centre of the drama of Herbrand's thought, balancing between an investigation always more concrete and a formalism always more abstract.

  8. Enriques' reviews
    • The first part of that work is concerned with the more general problems of the logic of science; the second part discusses the concepts of geometry, mechanics, physics, and biology.
    • After an introduction dealing with the presuppositions and limitations of the scientific concept of reality, the author proceeds to review the basic principles of logic, geometry, mechanics, and the mechanical theory of life.
    • The book contains six chapters treating in order the following topics: the general problem of knowledge and related matters; facts and theories and their interactions; the general problems of logic; the philosophical and psychological questions which are naturally raised in connection with the science of geometry; mechanics, its objective significance and the psychological development of its principles; the extension of mechanics into physics and the relation of the mechanical hypothesis to the phenomena of life.
    • It may be divided into five parts; the first is a general introduction and explanation of the author's position (which he calls Critical Positivism), the second deals with Logic and its applicability to the real world, the third deals with geometry, the fourth with the classical mechanics, and the last with electro-dynamics and the alterations which it has entailed in the mechanics of Newton.
    • The Historic Development of Logic.
    • Enriques does not claim completely to have recovered the spirit, but his noteworthy attempt should remind us how little has been done in the history of logic since Prantl.
    • While logicians dispute among themselves concerning the subject-matter of logic, whether it ought to be things, words, or ideas, Logos continues to be actualized in all forms of rational activity.
    • In order to determine the profounder bases of the principles employed by the mathematical sciences, Enriques has delved into the historical sources of logic, mathematics, and philosophy.
    • Enriques is well known for his mathematical, logical, philological, and historical knowledge which makes him pre-eminently equipped for the philosophical history of the sciences, as his 'Historic Development of Logic' shows.
    • Professor Enriques neatly summarizes the evidence from modern science against the Kantian doctrines of space, time, substance, causality, and logic.

  9. Keynes: 'Probability' Introduction Ch I
    • In most branches of academic logic, such as the theory of the syllogism or the geometry of ideal space, all the arguments aim at demonstrative certainty.
    • The course which the history of thought has led Logic to follow has encouraged the view that doubtful arguments are not within its scope.
    • If logic investigates the general principles of valid thought, the study of arguments, to which it is rational to attach some weight, is as much a part of it as the study of those which are demonstrative.
    • But in the sense important to logic, probability is not subjective.
    • This relation is the subject-matter of the logic of probability.
    • As soon as we have passed from the logic of implication and the categories of truth and falsehood to the logic of probability and the categories of knowledge, ignorance, and rational belief, we are paying attention to a new logical relation in which, although it is logical, we were not previously interested, and which cannot be explained or defined in terms of our previous notions.
    • If the statement that an opinion was probable on the evidence at first to hand, but became untenable on further information, is not, solely concerned with psychological belief, I do not know how the element of logical doubt is to be defined, or how its substance is to be stated, in terms of the other indefinables of formal logic.
    • In any case a desire to reduce the indefinables of logic can easily be carried too far.

  10. Bolzano's publications
    • This volume contains a biography of Bolzano together with details of the topics on which he worked: mathematics, logic, theology, philosophy and aesthetics.
    • This volume in the series of posthumous writings of the Collected works of Bernard Bolzano contains transcriptions of some early manuscripts which present his views in the 1810's on the foundations of logic, mathematics and physics.
    • Among the other contributions, a manuscript on the basic concepts of logic adumbrates fundamental themes in Bolzano's major work, the Wissenschaftslehre of 1837.
    • Most of the items on philosophy relate to logic.
    • Bernard Bolzano, Grundlegung der Logik (German), [Foundations of logic] Selected paragraphs from Wissenschaftslehre, Band I und II.
    • The first two volumes of Bolzano's Wissenschaftslehre published in 1837 are concerned with logic.
    • Bolzano's manuscript giving his ideas on logic and semantics which became the basis of his major publication Wissenschaftslehre which appeared in 1837.

  11. Karl Menger on Hans Hahn
    • Hans Hahn wrote eight philosophical papers on Empiricism, logic, and mathematics between 1919 and 1934.
    • Secondly, it was Hahn who directed the interest of the Circle toward logic.
    • Carnap, having been a student of Frege's, was well-versed in logic, but was mainly concerned with the philosophy of science at the time he moved to Vienna.
    • Hahn, however, right after his return, began an intense study of symbolic logic with an eye to related philosophical problems.
    • To me," Hahn continued, "the Tractatus has explained the role of logic." In later writings, which are included in this volume, Hahn expounded his own (somewhat oversimplifying) view by describing logic as "a prescription for saying the same thing in various ways, and for extracting from what is said all that is (in a strict sense) connoted." .
    • How stimulating his lectures were I have tried to describe - in Chapter 21 of my book Selected Papers in Logic and Foundations, Didactics, Economics (Vol.

  12. Keynes: 'Probability' Introduction Ch II
    • I do not wish to become involved in questions of epistemology to which I do not know the answer; and I am anxious to reach as soon as possible the particular part of philosophy or logic which is the subject of this book.
    • The logic of knowledge is mainly occupied with a study of the logical relations, direct acquaintance with which permits direct knowledge of the secondary proposition asserting the probability-relation, and so to indirect knowledge about, and in some cases of, the primary proposition.
    • In all knowledge, therefore, there is some direct element; and logic can never be made purely mechanical.
    • Almost up to the end of the seventeenth century the traditional treatment of modals is, in fact, a primitive attempt to bring the relations of probability within the scope of formal logic.] .
    • Other parts of knowledge - knowledge of the axioms of logic, for example - may seem more objective.
    • Further, the difference between some kinds of propositions over which human intuition seems to have power, and some over which it has none, may depend wholly upon the constitution of our minds and have no significance for a perfectly objective logic.
    • Our logic is concerned with drawing conclusions by a series of steps of certain specified kinds from a limited body of premisses.

  13. A N Whitehead addresses the British Association in 1916
    • The nature of induction, its importance, and the rules of inductive logic have been considered by a long series of thinkers, especially English thinkers, Bacon, Herschel, J S Mill, Venn, Jevons, and others.
    • There is a tendency in analysing scientific processes to assume a given assemblage of concepts applying to nature, and to imagine that the discovery of laws of nature consists in selecting by means of inductive logic some one out of a definite set of possible alternative relations which may hold between the things in nature answering to these obvious concepts.
    • King James said, 'No bishops, no king.' With greater confidence we can say, 'No logic, no science.' The reason for the instinctive dislike which most men of science feel towards the recognition of this truth is, I think, the barren failure of logical theory during the past three or four centuries.
    • To this hesitation I ascribe the barrenness of logic.
    • In the first place this last condemnation of logic neglects the fragmentary, disconnected character of human knowledge.
    • In fact, the true answer is embedded in the discussion of our main problem of the relation of logic to natural science.

  14. Aitken: 'Statistical Mathematics
    • The methods of logic and mathematics are then brought into play to develop the consequences of the axioms, producing an assemblage of theorems or propositions.
    • Probability as the Logic of Uncertain Inference.
    • One view is that probability may be regarded as a kind of extension of classical logic, an extension conveniently described as the "logic of uncertain inference." This view has been expounded by J M Keynes in A Treatise on Probability (London, 1921), especially in Part II, Chapters X-XVII, where references to earlier expositions are given.

  15. Carol R Karp: 'Languages with expressions of infinite length
    • The monograph is carefully and lucidly written and should make this field of logic accessible to a wider circle of logicians.
    • My interest in infinitary logic dates back to a February day in 1956 when I remarked to my thesis supervisor, Professor Leon Henkin, that a particularly vexing problem would be so simple if only I could write a formula that would say x = 0 or x = 1 or x = 2 etc.
    • Techniques for proving completeness theorems in logic and representation theorems for Boolean algebras combined to yield a completeness theorem: Valid formulas of denumerable length in which only finitely many variables can be quantified at a time are provable in a system very much like the ordinary first-order predicate calculus.
    • The present version of the material also owes much to the referee (not known to me) of an article submitted to the Journal of Symbolic Logic in 1962.

  16. Mathematics at Aberdeen 1
    • As in the other universities of Europe, the teaching was dominated by the Logic, Theoretical Physics and Metaphysics of Aristotle.
    • He should teach Logic in the first year, Physics, Natural Philosophy and the Treatise on the Sphere in the second.
    • The first year was occupied by Latin, Elementary Greek and Logic; the second mainly Logic with the writing and declaiming of Latin and Greek.

  17. Ernest Hobson addresses the British Association in 1910, Part 3
    • I am very far from wishing to minimise the high philosophic interest of the attempt made by the Peano-Russell school to exhibit Mathematics as a scheme of deductive logic.
    • Logic is, so to speak, the grammar of Mathematics; but a knowledge of the rules of grammar and the letters of the alphabet would not be sufficient equipment to enable a man to write a book.
    • After all, a mathematician is a human being, not a logic-engine.
    • I have already remarked that Euclid's treatment of the subject is not rigorous as regards logic.

  18. Kuratowski: 'Introduction to Set Theory
    • In the first part of this book the reader will find a certain amount of information on mathematical logic.
    • The notation of mathematical logic is an indispensable tool of set theory and can be applied with great profit far beyond set theory.
    • The notation of mathematical logic is not devoid of general didactical values; by examples for concepts such as uniform convergence or uniform continuity it is possible to observe how much the definition of these concepts gains in precision and lucidity, when they are written in the symbolism of mathematical logic.

  19. Mandelbrot's Foreword to Dauben's Abraham Robinson
    • Abraham Robinson's life was extraordinary in many ways, if only because his professional work spanned three significant fields: airplane design, symbolic logic, and mathematical analysis.
    • The second recounts the progression of Robinson's works, from airplane design to mathematical logic to nonstandard mathematical analysis.
    • As we follow in near-chronological order the life of a single individual of amazing brilliance, stamina, and versatility, we are guided back and forth without artificiality through at least three widely disparate academic cultures (pure and applied mathematics and logic-philosophy); six countries, representing six distinct flavours of Western culture; and, within the United States, two very different institutions.
    • I fully agree with this characterization, but I also hear the voice of the devil's advocate who would turn the same evidence around, interpret Abby's achievements backward, and assert that a person who spent much of his life outside of mathematics departments, working on airplane design and symbolic logic, was ipso facto not really a mathematician.

  20. Mandelbrot: Foreword to 'Abraham Robinson' by Dauben
    • Abraham Robinson's life was extraordinary in many ways, if only because his professional work spanned three significant fields: airplane design, symbolic logic, and mathematical analysis.
    • The second recounts the progression of Robinson's works, from airplane design to mathematical logic to nonstandard mathematical analysis.
    • As we follow in near-chronological order the life of a single individual of amazing brilliance, stamina, and versatility, we are guided back and forth without artificiality through at least three widely disparate academic cultures (pure and applied mathematics and logic-philosophy); six countries, representing six distinct flavours of Western culture; and, within the United States, two very different institutions.
    • I fully agree with this characterization, but I also hear the voice of the devil's advocate who would turn the same evidence around, interpret Abby's achievements backward, and assert that a person who spent much of his life outside of mathematics departments, working on airplane design and symbolic logic, was ipso facto not really a mathematician.

  21. A N Whitehead: 'Autobiographical Notes
    • Logic and Science are the disclosure of relevant patterns, and also procure the avoidance of irrelevancies.
    • Also Sir William Rowan Hamilton's Quaternions of 1853, and a preliminary paper in 1844, and Boole's Symbolic Logic of 1859, were almost equally influential on my thoughts.
    • My whole subsequent work on Mathematical Logic is derived from these sources.
    • The other experience is that of a Congress on Mathematical Logic held in Paris in March, 1914.

  22. R L Wilder: 'Cultural Basis of Mathematics III
    • The restricted mathematics known as Intuitionism has won only a small following, although some of its methods, such as those of a finite constructive character, seem to parallel the methods underlying the treatment of formal systems in symbolic logic, and some of its tenets, especially regarding constructive existence proofs, have found considerable favour.
    • From the extension of the notion of number to the transfinite, during the latter half of the 19th century, there evolved certain contradictions around the turn of the century, and as a consequence the study of Foundations questions, accompanied by a great development of mathematical logic, has increased during the last 50 years.
    • P W Bridgman, The logic of modern physics (Macmillan, New York, 1927).

  23. Isaac Todhunter: 'Euclid' Preface
    • After some hesitation on the point, all remarks relating to Logic have also been excluded.
    • Although the study of Logic appears to be reviving in this country, and may eventually obtain a more assured position than it now holds in a course of liberal education, yet at present few persons take up Logic before Geometry; and it seems therefore premature to devote space to a subject which will be altogether unsuitable to the majority of those who use a work like the present.

  24. Ernest Hobson addresses the British Association in 1910, Part 2
    • All attempts to characterise the domain of Mathematics by means-of a formal definition which shall not only be complete, but which shall also rigidly mark off that domain from the adjacent provinces of Formal Logic on the one side and of Physical Science on the other side, are almost certain to meet with but doubtful success; such success as they may attain will probably be only transient, in view of the power which the science has always shown of constantly extending its borders in unforeseen directions.
    • A strong tendency is manifested in many of the recent definitions to break down the line of demarcation which was formerly supposed to separate Mathematics from formal logic; the rise and development of symbolic logic has no doubt emphasised this tendency.

  25. Halmos: creative art
    • Mathematics is abstract thought, mathematics is pure logic, mathematics is creative art.
    • How do you choose your research problem, and what about it attracts you? Do you want to know about nature or about logic? Do you prefer concrete facts to abstract relations? If it's nature you want to study, if the concrete has the greater appeal, then you are a mathophysicist.
    • The angle trisection of the Greeks, the celebrated four-colour map problem, and Godel's spectacular contribution to mathematical logic are good because they are beautiful, because they are surprising, because we want to know, Don't all of us feel the irresistible pull of the puzzle? Is there really something wrong with saying that mathematics is a glorious creation of the human spirit and deserves to live even in the absence of any practical application? .

  26. Skolem: 'Abstract Set Theory
    • Further, there is a short remark on the possibility of finitist mathematics in a strict sense and finally some hints are given about the possibility of a set theory based on a logic with an Infinite number of truth values.
    • The possibility of set theory based on many-valued logic .
    • On the other hand it ought to be remarked that about the same time that Cantor exposed his ideas some other people were busy in developing what we today call mathematical logic.

    • The person lecturing to us was logic incarnate.
    • His pauses, hesitations, emphases, his betrayals of emotion (however rare), and sundry other nonverbal phenomena taught us a lot more logic than any written text could.

  28. Students in 1711
    • Latin was studied in the first year, then, in their second year, they also studied logic.
    • Kenneth and Thomas will be once through their Logic by the end of this week ..
    • we must either read our Logic course with application, or be affronted when the rest answer better than we.

  29. E W Hobson: 'Mathematical Education
    • In accordance with the older and traditional treatment of Mathematical instruction in our schools, Geometry was treated in a purely abstract manner; the idea being that Euclid, as a supposed model of purely deductive logic, should be studied entirely with a view to the development of the logical faculty.
    • That the average boy or girl is not by nature appreciative of formal logic, or of the interest and meaning of abstract symbols, was thought to be a reason why the subjects so treated should be especially insisted on.
    • He is not interested in formal logic, therefore he must not be bored with learning a chain of theorems of which the object is not apparent to him.

  33. Hans Hahn: 'The crisis in intuition
    • Because intuition turned out to be deceptive in so many instances, and because propositions that had been accounted true by intuition were repeatedly proved false by logic, mathematicians became more and more skeptical of the validity of intuition.
    • The task of completely formalizing mathematics, of reducing it entirely to logic, was arduous and difficult; it meant nothing less than a reform in root and branch ..

  34. Keynes: 'Probability' Preface
    • The subject matter of this book was first broached in the brain of Leibniz, who, in the dissertation, written in his twenty-third year, on the mode of electing the kings of Poland, conceived of Probability as a branch of Logic.
    • A few years before, "un probleme," in the words of Poisson, "propose a un austere janseniste par un homme du monde, a ete l'origine du calcul des probabilites." In the intervening centuries the algebraical exercises, in which the Chevalier de la Mere interested Pascal, have so far predominated in the learned world over the profounder enquiries of the philosopher into those processes of human faculty which, by determining reasonable preference, guide our choice, that Probability is oftener reckoned with Mathematics than with Logic.

  35. Gordon Preston on semigroups
    • Mathematical logic had a hard fight to be recognised as a part of mathematics.
    • John Crossley, for example, left the permanent job of fellow of All Soul's, at Oxford, surely one of the most enviable jobs for anyone to have, to come to Monash as a professor, because he saw a chance here, which he did not see at most universities in Britain, that mathematical logic would be treated as the important part of mathematics that it is.

  36. Gibson History 7 - Robert Simson
    • Simson's Opera Reliqua, published in 1776 from his MSS under the editorship of Professor Clow (Professor of Logic in Glasgow University), contains besides two short tracts on Logarithms and Limits the restoration of Apollonius's Determinate Section and Euclid's Porisms.
    • It is much to be regretted that he did not apply his profound knowledge of the Aristotelean logic to the somewhat crude reasonings of the founders of the modern algebra; had he devoted to this branch of mathematics a tithe of the labour he expended on the restoration of mutilated texts he would probably have had a more beneficial influence on the development of mathematics in Scotland.

  37. Horace Lamb addresses the British Association in 1904, Part 2
    • We have discussions on the principles of mechanics, on the foundations of geometry, on the logic of the most rudimentary arithmetical processes, as well as of the more artificial operations of the Calculus.
    • It is notorious that even in this realm of 'exact' thought discovery has often been in advance of strict logic, as in the theory of imaginaries, for example, and in the whole province of analysis of which Fourier's theorem is the type.

  38. Education in St Andrews in 1849
    • Until about twenty years ago, when the late Principal Nicoll resigned the church living of St Leonard's in favour of the late Dr James Hunter, professor of logic, the office of principal of the United College and the pastorship of St Leonard's parish, had, from the union of the Colleges, been vested in one individual.

  42. Andrew Forsyth addresses the British Association in 1905
    • He might, for instance, devote his attention to modern views of continuity, whether of quantity or of space; he might be heterodox or orthodox as to the so-called laws of motion; he might expound his notions as to the nature and properties of analytic functionality; a discussion of the hypotheses upon which a consistent system of geometry can be framed could be made as monumental as his ambition might choose; he could revel in an account of the most recent philosophical analysis of the foundations of mathematics, even of logic itself, in which all axioms must either be proved or be compounded of notions that defy resolution by the human intellect at the present day.

  43. Mathematics at Aberdeen 2

  47. Harold Jeffreys: 'Scientific Inference' Preface
    • Discussions from the philosophical and logical point of view have tended to the conclusion that this principle cannot be justified by logic alone, which is true, and have left it at that.

  48. Olds' teaching articles
    • When you have worked out a good definition for mathematics, test it by seeing whether it separates mathematics and physics, or mathematics and logic.

  53. Harold Jeffreys on Probability
    • The logical demonstration is right or wrong as a matter of the logic itself, and is not a matter for personal judgment.

  59. Dudeney: 'Amusements in mathematics' Preface
    • Every puzzle that is worthy of consideration can be referred to mathematics and logic.

  60. Einstein: 'Geometry and Experience
    • It seems to me that complete clearness as to this state of things first became common property through that new departure in mathematics which is known by the name of mathematical logic or "Axiomatics." The progress achieved by axiomatics consists in its having neatly separated the logical-formal from its objective or intuitive content; according to axiomatics the logical-formal alone forms the subject-matter of mathematics, which is not concerned with the intuitive or other content associated with the logical-formal.

  61. Poincaré on non-Euclidean geometry

  65. Mathematicians and Music
    • Other modes of expression and points of view were suggested by that great enthusiast to whom America owed much [Sylvester], him who called himself "the Mathematical Adam" because of the many mathematical terms he invented; for example, mathematic - to denote the science itself in the same way as we speak of logic, rhetoric or music, while the ordinary form is reserved for the applications of the science.

  66. De Coste on Mersenne
    • He studied with these learned men with great facility, not only literature, which because of its sweetness is called a Humanity, but also Logic, Physics, Metaphysics, Mathematics and some works on Theology, on all of which he thrived happily.

  70. Centenary of John Leslie
    • Leslie had dared to speak of Hume with approval, stating that he was the first to treat of causation (cause and effect) in a truly philosophical manner, and had remarked that "the unsophisticated notions of mankind are in perfect unison with the deductions of logic, and imply nothing more at bottom in the relation of cause and effect than a constant and invariable sequence." On this the Edinburgh Presbytery charged him with "having laid a foundation for rejecting all the argument that is derived from the works of God, to prove either His Being, or His Attributes." The protest which was tendered by the ministers to the patrons of the chair, then the Provost and Town Council, stated that they were obliged by charter to act with the advice of the ministers.

  71. De Thou on François Viète
    • But at this time this generous man did not recognise the full merit of his adversary, and thus could not forebear to show resentment when he was corrected by him although he had not in fact fully examined the logic of his own argument.

  72. Truesdell's books
    • (with Subramanyam Bharatha) The concepts and logic of classical thermodynamics as a theory of heat engines.

  73. Bertrand Russell on Euclid
    • Many more general criticisms might be passed on Euclid's methods, and on his conception of Geometry; but the above definite fallacies seem sufficient to show that the value of his work as a masterpiece of logic has been very grossly exaggerated.

  74. The Works of Sir John Leslie
    • He admires its power but mislikes it for apparently subordinating the logic.

  75. Science at St Andrews
