There 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 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 WeiningerThe decision must be made between Judaism and Christianity, between business and culture, between male and female, between the race and the individual, between unworhtiness and worth, between the earthly and the higher life, between negation and God-like. Mankind has the choice to make. There are only two poles, and there is no middle way.
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 is he whose ego has acquired consciousness. He is enabled by it to distinguish the fact that others are different, to perceive the "ego" of other men, even when it is not pronounced enough for them to be conscious of it themselves. But it is only he who feels that every other man is also an ego, a monad, an individual centre of the universe, with specific manner of feeling and thinking and a distinct past, he alone is in a position to avoid making use of his neighbours as means to an end.
