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.
Otto WeiningerA genius has perhaps scarcely ever appeared amongst the negroes, and the standard of their morality is almost universally so low that it is beginning to be acknowledged in America that their emancipation was an act of imprudence.
Otto WeiningerThere are probably very few people who have not at some time of their lives had some quality of genius. If they have not had such, it is probable that they have also been without great sorrow or great pain. They would have needed only to live sufficiently intently for a time for some quality to reveal itself. The poems of first love are a case in point, and certainly such love is a sufficient stimulus.
Otto WeiningerIn those rare individual cases where women approach genius they also approach masculinity.
