He who is firm and resolute in will molds the world to himself.

Oh, happy he who still hopes he can emerge from Error's boundless sea! - Faust.

Error is to truth as sleep is to waking. I have observed that one turns, as if refreshed, from error back to truth.

Let no one be ashamed to say yes today if yesterday he said no. Or to say no today if yesterday he said yes. For that is life. Never to have changed-what a pitiable thing of which to boast!

They should be ashamed of themselves, all these sober people!

Don't judge anyone harshly until you yourself have been through his experiences

The follies of the wise man are known to himself, but hidden from the world.
