When one has finished building one's house, one suddenly realizes that in the process one has learned something that one really needed to know in the worst way - before one began.

I am too inquisitive, too skeptical, too arrogant, to let myself be satisfied with an obvious and crass solution of things. God is such an obvious and crass solution; a solution which is a sheer indelicacy to us thinkers - at bottom He is really nothing but a coarse commandment against us: ye shall not think!

When, however, you have an enemy, then do not requite him good for evil: for that would shame him. Instead, prove that he did some good for you. And rather be angry than put to shame! And when you are cursed, I do not like it that you want to bless. Rather curse a little also! And if you are done a great injustice, then quickly add five small ones. Hideous to behold is he who is obsessed with an injustice.

Man is more sensitive to the contempt of others than to self-contempt.
