My formula for happiness: a Yes, a No, a straight line, a goal.

Truths are illlusions which we have forgotten are illusions.

Whoever does not know how to find the way to his ideal lives more frivolously and impudently than the man without an ideal.

Fear is the mother of morality.

Parasitism is the only practice of the church; with its ideal of anaemia, its holiness, draining all blood, all love, all hope for life; the beyond as the will to negate every reality; the cross as the mark of recognition for the most subterranean conspiracy that ever existed-against health, beauty, whatever has turned out well, courage, spirit, graciousness of the soul, against life itself.

My formula for greatness in a human being is amor fati: that one wants nothing to be different, not forward, not backward, not in all eternity. Not merely bear what is necessary, still less conceal it—all idealism is mendaciousness in the face of what is necessary—but love it

Faith: not wanting to know what is true.
