It is very important in life to know when your cue comes.

And this is the simple truth - that to live is to feel oneself lost. He who accepts it has already begun to find himself, to be on firm ground. Instinctively, as do the shipwrecked, he will look around for something to which to cling, and that tragic, ruthless glance, absolutely sincere, because it is a question of his salvation, will cause him to bring order into the chaos of his life. These are the only genuine ideas; the ideas of the shipwrecked. All the rest is rhetoric, posturing, farce.

There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.

It is (to describe it figuratively) as if an author were to make a slip of the pen, and as if this clerical error became conscious of being such. Perhaps this was no error but in a far higher sense was an essential part of the whole exposition. It is, then, as if this clerical error were to revolt against the author, out of hatred for him, were to forbid him to correct it, and were to say, "No, I will not be erased, I will stand as a witness against thee, that thou art a very poor writer."

It is the duty of the human understanding to understand that there are things which it cannot understand, and what those things are. Human understanding has vulgarly occupied itself with nothing but understanding, but if it would only take the trouble to understand itself at the same time it would simply have to posit the paradox.

What I really need is to get clear about what I must do, not what I must know, except insofar as knowledge must precede every act. What matters is to find a purpose, to see what it really is that God wills that I shall do; the crucial thing is to find a truth which is truth for me, to find the idea for which I am willing to live and die.

Do it or don't do it - you will regret both.
