But this word will I say to my enemies: What is all manslaughter in comparison with what you have done to me!

The strongest and most evil spirits have to date advanced mankind the most: they always rekindled the sleeping passions - all orderly arranged society lulls the passions to sleep; they always reawakened the sense of comparison, of contradiction, of delight in the new, the adventurous, the untried; they compelled men to set opinion against opinion, ideal plan against ideal plan.

Love brings to light the lofty and hidden characteristics of the lover--what is rare and exceptional in him: to that extent it caneasily be deceptive with respect to what is normal in him.

When a hundred men stand together, each of them loses his mind and gets another one.

Man, however, is the most courageous animal: thereby has he overcome every animal. With sound of triumph has he overcome every pain; human pain, however, is the sorest pain.

With the unknown, one is confronted with danger, discomfort, and care; the first instinct is to abolish these painful states. First principle: any explanation is better than none. . . . The causal instinct is thus conditional upon, and excited by, the feeling of fear. The "why?" shall, if at all possible, not give the cause for its own sake so much as for a particular kind of cause -- a cause that is comforting, liberating, and relieving.

A man should not play the coward to his deeds. He should not repudiate them once he has performed them. Pangs of conscience are indecent.
