Michel de Montaigne, On Friendship.
My defects are becoming natural and incorrigible, but as fine gentlemen serve the public as models to follow, I may serve a turn as a model to avoid . . .
The act of publishing and indicting my imperfections may teach someone how to fear them. (The talents which I most esteem in myself derive more honor from indicting me than praising me.) That is why I so often return to it and linger over it. Yet, when all has been said, you never talk about yourself without loss: condemn yourself and you are always believed -- praise yourself and you never are.
