A quote
No man ought to glory except in that which is his own. We praise a vine if it makes the shoots teem with increase, if by its weight it bends to the ground the very poles which hold its fruit; would any man prefer to this vine one from which golden grapes and golden leaves hang down? In a vine the virtue peculiarly its own is fertility; in man also we should praise that which is his own. Suppose that he has a retinue of comely slaves and a beautiful house, that his farm is large and large his income; none of these things is in the man himself; they are all on the outside.
