Ethics, too, are nothing but reverence for life. This is what gives me the fundamental principle of morality, namely, that good consists in maintaining, promoting, and enhancing life, and that destroying, injuring, and limiting life are evil.

The quiet conscience is the invention of the devil. No one of us may permit any preventable pain to be inflicted even though the responsibility for that pain is not ours. No one may shut his eyes and think that the pain which is therefore not visible, is non-existent.

There is within each of us a modulation, an inner exaltation, which lifts us above the buffetings with which events assail us. Likewise, it lifts us above dependence upon the gifts of events for our joy.

If a man loses his reverence for any part of life, he will lose his reverence for all of life.

But merely accepting authoritarian truth, even if that truth has some virtue, does not bring skepticism to an end. To blindly accept a truth one has never reflected upon retards the advance of reason. Our world rots in deceit. . . . Just as a tree bears the same fruit year after year and at the same time fruit that is new each year, so must all permanently valuable ideas be continually created anew in thought. But our age pretends to make a sterile tree bear fruit by tying fruits of truth onto its branches.

Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly if they even roll a few more upon it.

A man is ethical only when life, as such, is sacred to him.
