You shall not steal! You shall not kill! Such words were once called holy; before them people bowrd their knees and heads, and removed their shoes. But I ask you: where have there ever been better thieves and killers in the world than such holy words have been? Is there not in all of life itself - robbing and killing? And when such words were called holy, was not truth itself thereby - killed?

We should conserve evil just as we should conserve the forests. It is true that by thinning and clearing the forests the earth grew warmer.

The question of place and climate is most closely related to the question of nutrition. Nobody is free to live everywhere; and whoever has to solve great problems that challenge all his strength actually has a very restricted choice in this matter. The influence of climate on our metabolism, its retardation, its acceleration, goes so far that a mistaken choice of place and climate can not only estrange a man from his task but can actually keep it from him: he never gets to see it.

A certain sense of cruelty towards oneself and others is Christian; hatred of those who think differently; the will to persecute. Mortal hostility against the masters of the earth, against the 'noble', that is also Christian; hatred of mind, of pride, courage, freedom, libertinage of mind, is Christian; hatred of the senses, of joy in general, is Christian.

In compassionate men, severity is a virtue.

Everyone needs a sense of shame, but no one needs to feel ashamed.

That which does not destroy, strengthens.
