Belief is not the beginning of knowledge- it is the end.
Johann Wolfgang von Goethe
To measure up to all that is demanded of him, a man must overestimate his capacities.
In contemplation as in action, we must distinguish between what may be attained and what is unattainable. Without this, little can be achieved, either in life or in knowledge.
He who has never despaired has no need to have lived.
So much simplicity with so much understanding — so mild, and yet so resolute — a mind so placid, and a life so active.
Know thyself? If I knew myself, I'd run away.
