You must not take conceited pride in any deed, because deeds are measured on the basis of their final seal (their ultimate condition)
The price good men pay for indifference to public affairs is to be ruled by evil men
The clearest way into the Universe is through a forest wilderness
Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness
The only true wisdom is in knowing you know nothing
I am the wisest man alive, for I know one thing, and that is that I know nothing
From a small seed a mighty trunk may grow.
