Identity and sexuality (2)

1.) Whatever the number of human sexes, they are contraries in one species.

2.) If sex contraries are said of the human species as such, only humans have sexual difference.

3.) If sex differences are accidental, sexual difference has no value in describing any species.

4.) The consequent of (3) is obviously false: sexual dimorphism or uniformity is a primary and essential description of many species.

5.) The sexes are neither said of the species nor are accidental. Therefore they are differences within the genus as genus. The genus is clearly not restricted to any biological kingdom but is said properly of life.

6.) Any account of sexual difference has to appeal to an essential feature belonging to life as life. The account we give of sexual contrariety must be essential to even rudimentary forms of life. Sexuality is tied to identity at an ur-level that is subtends any formal difference, even one constituting the kingdoms.

7.) Sexual difference is complex enough to develop in stages, but the end result of this complexity has to also be explicable in terms of life as such.

8.) Life generates, i.e. it is (a) capable of a division giving rise to one and the same organism (b) existing in a more and less mature state. The more mature state is called parent and the less mature offspring. There are times when only (a) occurs, e.g. when an embryo divides into identical twins, but this is not generation since it happens without (b).
