People demand freedom of speech as a compensation for the freedom of thought which they seldom use.

The truly simple way of presenting Christianity is to do it.

The greatest danger to Christianity is, I contend, not heresies, not heterodoxies, not atheists, not profane secularism - no, but the kind of orthodoxy which is cordial drivel, mediocrity served up sweet. There is nothing that so insidiously displaces the majestic as cordiality.

The truth must essentially be regarded as in conflict with this world; the world has never been so good, and will never become so good that the majority will desire the truth.

I do not care for anything. I do not care to ride, for the exercise is too violent. I do not care to walk, walking is too strenuous. I do not care to lie down, for I should either have to remain lying, and I do not care to do that, or I should have to get up again, and I do not care to do that either. Summa summarum: I do not care at all.

Knowledge of the truth I may perhaps have attained to; happiness certainly not. What shall I do? Accomplish something in the world, men tell me. Shall I then publish my grief to the world, contribute one more proof for the wretchedness and misery of existence, perhaps discover a new flaw in human life, hitherto unnoticed? I might then reap the rare reward of becoming famous, like the man who discovered the spots on Jupiter. I prefer, however, to keep silent.

During the first period of our lives the greatest danger is not to take the risk. When once the risk has been taken, then the greatest danger is to risk too much. By not risking at first one turns aside and serves trivialities; in the second case, by risking too much, one turns aside to the fantastic and perhaps to presumption.
