The mode of cultivating or developing each soul is the same--to assign to each the nourishment and the movement which is suitable to it. Now the movements which are kindred and congenial to our divine encephalic soul, are--the rotations of the Kosmos and the intellections traversing the Kosmical soul. It is these that we ought to follow and study. By learning and embracing in our minds the rotations and proportions of the Kosmos, we shall assimilate the comprehending subject to the comprehended object, and shall rectify that derangement of our own intra-cranial rotations, which was entailed upon us by our birth into a body. By such assimilation, we shall attain the perfection of the life allotted to us, both at present and for the future.[113] [Footnote 113: Plato, Timæus, pp. 90 D, 91 C-D. The phrase of Plato in describing the newly introduced mode of procreation--[Greek: ô(s ei)s a)/rouran tê\n mê/tran a)o/rata u(po\ smikro/têtos kai\ a)dia/plasta zô=a kataspei/rantes]--is remarkable, as it might be applied to the spermatozoa, which nevertheless he cannot have known.] [Side-note: Construction of women, birds, quadrupeds, fishes, &c., all from the degradation of primitive man.] We have thus--says the Platonic Timæus in approaching his conclusion--gone through all those matters which we promised at the beginning, from the first construction of the Kosmos to the genesis of man. We must now devote a few words to the other animals. All of these derive their origin from man, by successive degradations. The first transition is from man into woman. Men whose lives had been characterised by cowardice or injustice, were after death and in their second birth born again as women. It was then that the Gods planted in us the sexual impulse, reconstructing the bodily organism with suitable adjustment, on the double pattern, male and female.[114] [Footnote 114: Plat. Tim. p. 91 D. Whoever compares the step of marked degeneration here indicated--in passing from men to women--with that which is affirmed by Plato in the fifth book of the Republic about the character, attributes, and capacities of women, will recognise a material difference between the two.] Such was the genesis of women, by a partial transformation and diversification of the male structure. We next come to birds; who are likewise a degraded birth or formation, derived from one peculiar mode of degeneracy in man: hair being transmuted into feathers and wings. Birds were formed from the harmless, but light, airy, and superficial men; who, though carrying their minds aloft to the study of kosmical phenomena, studied them by visual observation and not by reason, foolishly imagining that they had discovered the way of reaching truth.[115] [Footnote 115: Plato, Timæus, p. 91 E.]
