M. Tullius Cicero, Against Piso
C. D. Yonge, Ed.

Some one will say, “How did you find out all this?” I will not indeed, describe any one in such a manner as to insult him, especially if he be an ingenious and learned man, a class with whom I could not be angry, even if I wished it. There is a certain Greek who lives with him, a man, to tell the truth, (I speak as I have found him,) of good manners, at least as long as he is in other company than Piso's, or while he is by himself. He, when he had met that man, as a young man, though even then he had an expression of countenance as if he were angry with the gods, did not disdain his friendship, as the other sought for it with great eagerness; he gave himself up to intimacy with him, so as indeed to live wholly with him, and I may almost say, never to depart from him. I am speaking not before illiterate men, but, as I imagine, in a company of the most learned and highly accomplished men possible. You have no doubt heard it said, that the Epicurean philosophers measure everything which a man ought to desire by pleasure;—whether that is truly said or not is nothing to us, or if it be anything to us, it certainly has no bearing on the present subject; but still it is a tempting sort of argument for a young man, and one always dangerous to a person of no great intelligence.
