The unhappy person is never present to themself because they always live in the past or the future.

Trouble is the common denominator of living. It is the great equalizer.

The only analogy I have before me is Socrates. My task is a Socratic task, to revise the definition of what it is to be a Christian. For my part I do not call myself a "Christian" (thus keeping the ideal free), but I am able to make it evident that the others are still less than I.

It is human self-renunciation when a man denies himself and the world opens up to him. But it is Christian self-renunciation when he denies himself and, because the world precisely for this shuts itself up to him, he must as one thrust out by the world seek God's confidence. The double-danger lies precisely in meeting opposition there where he had expected to find support, and he has to turn about twice; whereas the merely human self-resignation turns once.

Silence is the demon's trap, and the more one is silenced, the more terrible the demon; but silence is also the divinity's mutual understanding with the single individual.

Genius never desires what does not exist.

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.
