The inevitable trend of human life is toward higher civilization; but, while that civilization is confined to one sex, it inevitably exaggerates sex-distinction, until the increasing evil of this condition is stronger than all the good of the civilization attained, and the nation falls. Civilization, be it understood, does not consist in the acquisition of luxuries. Social development is an organic development. A civilized State is one in which the citizens live in organic industrial relation. The more full, free, subtle, and easy that relation; the more perfect the differentiation of labor and exchange of product, with their correlative institutions,—the more perfect is that civilization. To eat, drink, sleep, and keep warm,—these are common to all animals, whether the animal couches in a bed of leaves or one of eiderdown, sleeps in the sun to avoid the wind or builds a furnace-heated house, lies in wait for game or orders a dinner at a hotel. These are but individual animal processes. Whether one lays an egg or a million eggs, whether one bears a cub, a kitten, or a baby, whether one broods its chickens, guards its litter, or tends a nursery full of children, these are but individual animal processes. But to serve each other more and more widely; to live only by such service; to develope special functions, so that we depend for our living on society’s return for services that can be of no direct use to ourselves,—this is civilization, our human glory and race-distinction. All this human progress has been accomplished by men. Women have been left behind, outside, below, having no social relation whatever, merely the sex-relation, whereby they lived. Let us bear in mind that all the tender ties of family are ties of blood, of sex-relationship. A friend, a comrade, a partner,—this is a human relative. Father, mother, son, daughter, sister, brother, husband, wife,—these are sex-relatives. Blood is thicker than water, we say. True. But ties of blood are not those that ring the world with the succeeding waves of progressive religion, art, science, commerce, education, all that makes us human. Man is the human creature. Woman has been checked, starved, aborted in human growth; and the swelling forces of race-development have been driven back in each generation to work in her through sex-functions alone. This is the way in which the sexuo-economic relation has operated in our species, checking race-development in half of us, and stimulating sex-development in both. V.
