We can redeem anyone who strives unceasingly.

We do not have to visit a madhouse to find disordered minds; our planet is the mental institution of the universe.

Wishes are premonitions of abilities.

Excellence is rarely found, more rarely valued.

Nothing will change the fact that I cannot produce the least thing without absolute solitude.

No two men see the world exactly alike, and different temperaments will apply in different ways a principle that they both acknowledge.

Just begin and the mind grows heated; continue, and the task will be completed!
