Christians remind me of schoolboys who want to look up the answers to their math problems in the back of the book rather than work them through.

There are many people who reach their conclusions about life like schoolboys: they cheat their master by copying the answer out of a book without having worked the sum out for themselves.

The thing that cowardice fears most is decision

Hope is passion for what is possible.

People generally think that it is the world, the environment, external relationships, which stand in one's way, in the way of ones' good fortune... and at bottom it is always man himself that stands in his own way.

It belongs to the imperfection of everything human that man can only attain his desire by passing through its opposite.

No one is so terribly deceived as he who does not himself suspect it.
