Mankind occurs as male or female, as something or nothing. Woman has no share in ontological reality, no relation to the thing-in-itself, which, in the deepest interpretation, is the absolute, is God. Man in his highest form, the genius, has such a relation, and for him the absolute is either the conception of the highest worth of existence, in which case he is a philosopher; or it is the wonderful fairyland of dreams, the kingdom of absolute beauty, and then he is an artist.
Otto WeiningerThe 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.
Otto WeiningerNo men who really think deeply about women retain a high opinion of them; men either despise women or they have never thought seriously about them.
Otto WeiningerIt is certainly true that most men need some kind of a God. A few, and they are the men of genius, do not bow to an alien law. The rest try to justify their doings and misdoings, their thinking and existence (at least the menial side of it), to some one else, whether it be the personal God of the Jews, or a beloved, respected, and revered human being. It is only in this way that they can bring their lives under the social law. . . .
Otto WeiningerNo 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. . . .
