An accomplished mathematician, i.e. a most wretched orator.
Mathematical Lectures
It may be observed in mathematicians that they only meddle with such things as are certain, passing by those that are doubtful and unknown. They profess not to know all things, neither do they affect to speak of all things. What they know to be true, and can make good by invincible arguments, they publish and insert among their theorems. Of other things they are silent and pass no judgement at all, choosing rather to acknowledge their ignorance, than affirm anything rashly.
Mathematical Lectures
Because Mathematicians frequently make use of Time, they ought to have a distinct idea of the meaning of that Word, otherwise they are Quacks.
