Talent is hereditary; it may be the common possession of a whole family (eg, the Bach family); genius is not transmitted; it is never diffused, but is strictly individual.

The man of genius possesses, like everything else, the complete female in himself; but woman herself is only a part of the Universe, and the part can never be the whole; femaleness can never include genius. This lack of genius on the part of woman is inevitable because woman is not a monad, and cannot reflect the Universe.

Universality is the distinguishing mark of genius. There is no such thing as a special genius, a genius for mathematics, or for music, or even for chess, but only a universal genius. The genius is a man who knows everything without having learned it.

No one suffers so much as he [the genius] with the people, and, therefore, for the people, with whom he lives. For, in a certain sense, it is certainly only "by suffering" that a man knows. If compassion is not itself clear, abstractly conceivable or visibly symbolic knowledge, it is, at any rate, the strongest impulse for the acquisition of knowledge. It is only by suffering that the genius understands men. And the genius suffers most because he suffers with and in each and all; but he suffers most through his understanding. . . .

The genius which runs to madness is no longer genius.

In those rare individual cases where women approach genius they also approach masculinity.

Logic and ethics are fundamentally the same, they are no more than duty to oneself
