1.6.2 (Antiphon is speaking, tr. E.C. Marchant):
"Socrates, I supposed that philosophy must add to one's store of happiness. But the fruits you have reaped from philosophy are apparently very different. For example, you are living a life that would drive even a slave to desert his master. Your meat and drink are of the poorest; the cloak you wear is not only a poor thing, but is never changed summer or winter; and you never wear shoes or tunic. Besides you refuse to take money, the mere getting of which is a joy, while its possession makes one more independent and happier. Now the professors of other subjects try to make their pupils copy their teachers: if you too intend to make your companions do that, you must consider yourself a professor of unhappiness [kakodaimonias didaskalos]."
