Aristotle’s philosophy searches for demonstrations most assiduously, and therefore it surpasses all sects by far. And it judges correctly about the purpose of moral goods and the nature of virtue, at least if it is understood as being about civic life and civic virtues.Nevertheless, philosophy is not contained within such narrow confines that one need assume that it is all included in the books written by Aristotle that have come down to us, but its elements are in Aristotle. Mathematicians, physicians and lawyers build on these as if on foundations.
