These amazing conclusions concerning the origins of life and reproduction—here, of course, very briefly and imperfectly presented—cannot but give us pause. Contemplating the evolutions and affinities of these infinitely numerous but infinitely small organisms which build up our visible selves, and the strange intelligence which seems to pervade their movements, the mind reels—somewhat as it does in contemplating the evolutions and affinities of the unimaginable stars.[18] We seem, certainly, to trace the same laws or operations in these minutest regions as we trace in our own corporeal and mental relations. Cells attract each other just as human beings do; and the attraction seems to depend, to a certain degree, on difference. The male spermatozoon seeks the female ovum, just as the male animal, as a rule, seeks and pursues the female. Primitive cells divide and redivide and differentiate themselves, building up the animal body, just in the same way as primitive thoughts and emotions divide and redivide and differentiate themselves, building up the human mind. But though we thus see processes with which we are familiar repeated in infinitesimal miniature, we seem to be no nearer than before to any ‘explanation’ of them, and we seem to see no promise of any explanation. We merely obtain a larger perspective, and a suggestion that the universal order is of the same character throughout—with a suspicion perhaps that the explanation of these processes does not lie in any concatenation of the things themselves, but in some other plane of being of which these concatenations are an allegory or symbolic expression. In portions of the following chapters I shall trace more in detail the resemblance or parallelism between these processes among the Protozoa and some of our own experiences in the great matters of Life and Love and Death.[19] CHAPTER III LOVE AS AN ART
