The drive toward knowledge has a moral origin.

The will to power can express itself only against resistances; it seeks that which resists it--this is the native tendency of theamoeba when it extends its pseudopodia and gropes around.

Cows sometimes wear an expression resembling wonderment arrested on its way to becoming a question. In the eye of superior intelligence, on the other hand, lies the nil admirari spread out like the monotony of a cloudless sky.

Woman is essentially unpeaceful, like the cat, however well she may have trained herself to present an appearance of peace.

In the knowledge of truth, what really matters is the possession of it, not the impulse under which it was sought.

A thought, even a possibility, can shatter and transform us.

It quite often happens that the old man is subject to the delusion of a great moral renewal and rebirth, and from this experience he passes judgments on the work and course of his life, as if he had only now become clear-sighted; and yet the inspiration behind this feeling of well-being and these confident judgements is not wisdom, but weariness .
