Art raises its head where creeds relax.

It is certainly not the least charm of a theory that it is refutable; it is precisely thereby that it attracts the more subtle minds. It seems that the hundred-times-refuted theory of the "free will" owes its persistence to this charm alone; some one is always appearing who feels himself strong enough to refute it.

When we stand the truth on its head we generally fail to notice that our head is not standing where it should be standing either.

However modest one may be in one's demand for intellectual cleanliness, one cannot help feeling, when coming into contact with the New Testament, a kind of inexpressible discomfiture: for the unchecked impudence with which the least qualified want to raise their voice on the greatest problems, and even claim to be judges of such things, surpasses all measure. The shameless levity with which the most intractable problems (life, world, God, purpose of life) are spoken of, as if they were not problems at all but simply things that these little bigots knew!

If virtue goes to sleep, it will be more vigorous when it awakes.

One does not hate so long as one continues to rate low, but only when one has come to rate equal or higher.

The will to truth is merely the longing for a stable world.
