Our nature consists in motion; complete rest is death.
We view things not only from different sides, but with different eyes; we have no wish to find them alike.
The greatness of man is great in that he knows himself to be wretched. A tree does not know itself to be wretched.
Man's true nature being lost, everything becomes his nature; as, his true good being lost, everything becomes his good.
Vanity is but the surface.
Do you wish people to think well of you? Don't speak well of yourself.
