Nothing on earth consumes a man more quickly than the passion of resentment.

Whoever feels predestined to see and not to believe will find all believers too noisy and pushy: he guards against them.

Morality is the herd-instinct in the individual.

Crude men who feel themselves insulted tend to assess the degree of insult as high as possible, and talk about the offense in greatly exaggerated language, only so they can revel to their heart's content in the aroused feelings of hatred and revenge.

Man is the cruelest animal.

Madness is the result not of uncertainty but certainty.

I am the leading strings of the ego and the prompter of its concepts.
