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 WeiningerThere are transitional forms between the metals and non-metals; between chemical combinations and simple mixtures, between animals and plants, between phanerogams and cryptogams, and between mammals and birds [...]. The improbability may henceforth be taken for granted of finding in Nature a sharp cleavage between all that is masculine on the one side and all that is feminine on the other; or that any living being is so simple in this respect that it can be put wholly on one side, or wholly on the other, of the line.
Otto WeiningerBut the higher a man mounts, the greater may be his fall; all genius is a conquering of chaos, mystery.
Otto WeiningerA nation orients itself by its own geniuses, and derives from them its ideas of its own ideals, but the guiding star serves also as a light to other nations. As speech has been created by a few great men, the most extraordinary wisdom lies concealed in it, a wisdom which reveals itself to a few ardent explorers but which is usually overlooked by the stupid professional philologists.
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.
