<blockquote>Sosicrates, too, in the third book of The Succession of Philosophers, records that Diodorus adopted the wearing of a long beard, put on a worn cloak, and grew long hair, introducing this practice as an innovation in order to gratify a kind of vanity, since the Pythagoreans before his time always dressed in white clothing and made use of baths, ointments, and the customary mode of hair-cut. Now if, my philosophers, you really love independence and cheap things to eat, why do you come here where you have not even been invited? Is it as though you had come into a prodigal's house to learn how to make a list of cooking utensils? Or to recite the Cephalion of Diogenes? For, in the words of the Cedalion of Sophocles, ye are 'rogues from the whipping-post and the rack, devourers of other men's goods.'
