Have you not, on the contrary, contributed to advancing true charges against yourselves? because, by expressing your approval of what is good, and philosophising as far as words go, you have been excellent interpreters, but are nevertheless discovered to be men who both think and practise shameful things. In fact, all good things are dead in your souls, these evils having been there kindled; and, on this account there is no one of you who is really alive.
