Letters 118.10

The present topic suggests that I state the difference between the Good and the honourable. Now they have a certain quality which blends with both and is inseparable from either: nothing can be good unless it contains an element of the honourable, and the honourable is necessarily good. What, then, is the difference between these two qualities? The honourable is the perfect Good, and the happy life is fulfilled thereby; through its influence other things also are rendered good.
