Nor was Pythagoras the inventor only of the name, but he enlarged also the thing itself, and, when he came into Italy after this conversation at Phlius, he adorned that Greece, which is called Great Greece, both privately and publicly, with the most excellent institutions and arts; but of his school and system I shall, perhaps, find another opportunity to speak.

But numbers and motions, and the beginning and end of all things, were the subjects of the ancient philosophy down to Socrates, who was a pupil of Archelaus, who had been the disciple of Anaxagoras.

These made diligent inquiry into the magnitude of the stars, their distances, courses, and all that relates to the heavens.

But Socrates was the first who brought down philosophy from the heavens, placed it in cities, introduced it into families, and obliged it to examine into life and morals, and good and evil.

And his different methods of discussing questions, together with the variety of his topics, and the greatness of his abilities, being immortalized by the memory and writings of Plato, gave rise to many sects of philosophers of different sentiments, of all which I have principally adhered to that one which, in my opinion, Socrates himself followed; and argue so as to conceal my own opinion, while I deliver others from their errors, and so discover what has the greatest appearance of probability in every question.
