Antiphon, as another man gets pleasure from a good horse, or a dog, or a bird, I get even more pleasure from good friends. And if I have something good, I teach it to them, and I introduce them to others who will be useful to them with respect to virtue. And together with my friends I go through the treasures of wise men of old which they left behind written in books, and we peruse them. If we see something good, we pick it out and hold it to be a great profit, if we are able to prove useful to one another.
