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 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 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.
