I. The True Place of Man.
We have too long been accustomed to study human society as if man were a being apart in the universe. In comparing human bipeds with animals it has seemed as if we were disparaging these so-called demi-gods. It is to this blind prejudice that we must attribute the tardy rise of anthropological sociology. A deeper knowledge of biological science and of inferior races has at last cured us of this childish vanity. We have decided to assign to man his true place in the organic world of our little globe. Granted that the human biped is incontestably the most intelligent of terrestrial animals, yet, by his histological texture, by his organs, and by the functions of these organs, he is evidently only an animal, and easily classed in the series: he is a bimanous, mammiferous vertebrate. Not that by his most glorious representatives, by those whom we call men of genius, man does not rise prodigiously above his distant relations of the mammal class; but, on the other hand, by imperfectly developed specimens he descends far below many species of animals; for if the idiot is only an exception, the man of genius is still more so. In fact, the lowest human races, with whose anatomy, psychology, and sociology we are to-day familiar, can only inspire us with feelings of modesty. They furnish studies in ethnography which have struck a mortal blow at the dreams of “the kingdom of man.”
When once it is established that man is a mammal like any other, and only distinguished from the animals of his class by a greater cerebral development, all study of human sociology must logically be preceded by a corresponding study of animal sociology. Moreover, as sociology finally depends on biology, it will be necessary to seek in physiological conditions themselves the origin of great sociological manifestations. The first necessity of societies is that they should endure, and they can only do so on the condition of providing satisfaction for primordial needs, which are the condition of life itself, and which imperatively dominate and regulate great social institutions. Lastly, if man is a sociable animal, he is not the only one; many other species[Pg 3] have grouped themselves in societies, where, however rudimentary they may be, we find in embryonic sketch the principal traits of human agglomerations. There are even species—as, for example, bees, ants, and termites—that have created true republics, of complicated structure, in which the social problem has been solved in an entirely original manner. We may take from them more than one good example, and more than one valuable hint.
My present task is to write the history of marriage and of the family. The institution of marriage has had no other object than the regulation of sexual unions. These have for their aim the satisfaction of one of the most imperious biological needs—the sexual appetite; but this appetite is only a conscious impulse, a “snare,” as Montaigne calls it, which impels both man and animal to provide, as far as concerns them, for the preservation of their species—to “pay the ancestral debt,” according to the Brahmanical formula. Before studying the sexual relations, and their more or less regulated form in human societies, it will not be out of place to say a few words on reproduction in general, to sketch briefly its physiology in so far as this is fundamental, and to show how tyrannical are the instincts whose formation has been determined by physiological causes, and which render the fiercest animals mild and tractable. This is what I shall attempt to do in the following chapter.
II. Reproduction.
Stendhal has somewhere said that the beautiful is simply the outcome of the useful; changing the phrase, we may say that generation is the outcome of nutrition. If we examine the processes of generation in very simple organisms, this great function seems to answer to a superabundance of nutritive materials, which, after having carried the anatomic elements to their maximum volume, at length overflows and provokes the formation of new elements. As long as the new-born elements can remain aggregated with those which already constitute the individual, as long as the latter has not acquired all the development compatible with[Pg 4] the plan of its being, there is simply growth. When once the limit is attained that the species cannot pass, the organism (I mean a very rudimentary organism) reproduces itself commonly by a simple division in two halves. It perishes in doubling itself and in producing two beings, similar to itself, and having nothing to do but grow. It is by means of this bi-partition that hydras, vorticellæ, algæ, and the lowest mushrooms are generally propagated.
In the organisms that are slightly more complicated the function of reproduction tends to be specialised. The individual is no longer totally divided; it produces a bud which grows by degrees, and detaches itself from the parent organism to run in its turn through the very limited adventures of its meagre existence.
By a more advanced step in specialisation the function of reproduction becomes localised in a particular cell, an ovule, and the latter, by a series of repeated bi-partitions, develops a new individual; but it is generally necessary that the cellule destined to multiply itself by segmentation should at first dissolve by union with another cell. Through the action of various organic processes the two generating cells arrive in contact. The element which is to undergo segmentation—the female element—then absorbs the element that is simply impulsive; the element called male becomes impregnated with it, and from that moment it is fertilised, that is to say, capable of pursuing the course of its formative work.
This phenomenon, so simple in itself, of the conjugation of two cellules, is the foundation of reproduction in the two organic kingdoms as soon as the two sexes are separated. Whether the sexes are represented by distinct or united individuals, whether the accessory organic apparatus is more or less complicated, are matters of no consequence; the essential fact reappears always and everywhere of the conjugation of two cellules, with absorption, in the case of superior animals, of the male cellule by the female cellule.
The process may be observed in its most elementary form in the algæ and the diatomaceæ, said to be conjugated. To form a reproductive cellule, or spore, two neighbouring cellules each throw out, one towards the other, a prolongation.[Pg 5] These prolongations meet, and their sides absorb each other at the point of contact; then the protoplasms of the two elements mingle, and at length the two cellules melt into a single reproductive cellule (Spirogyra longata).
Between this marriage of two lower vegetal cellules, which realises to the letter the celebrated biblical words, “they shall be one flesh,” or rather one protoplasm, and the fundamental phenomenon of fecundation in the superior animals, including man, there is no essential dissimilarity. The ovule of the female and the spermatozoon of the male become fused in the same manner, with this difference only, that the feminine cellule, the ovule, preserves its individuality and absorbs the masculine cellule, or is impregnated by it.
But, simple as it is, this phenomenon of fecundation is the sole reason of the duration of bi-sexual species. Thanks to it, organic individuals that are all more or less ephemeral,
“Et, quasi cursores, vitaï lampada tradunt.”
(Lucretius, ii. 78.)
For many organised beings reproduction seems in reality the supreme object of existence. Numbers of vegetables and of animals, even of animals high in the series—as insects—die as soon as they have accomplished this great duty. Sometimes the male expires before having detached himself from the female, and the latter herself survives just long enough to effect the laying of eggs. Instead of laying eggs, the female cochineal fills herself with eggs to such a degree that she dies in consequence, and the tegument of her body is transformed into a protecting envelope for the eggs.
At the not very distant time when animism reigned supreme, these facts were attributed to calculations of design. Nature, it was believed, occupied herself chiefly with perpetuating organised species; as for individuals, she disdained the care of them. We now know that Nature, as an anthropomorphic being, does not exist; that the great forces called natural are unconscious; that their blind action results, however, in the world of life, in a choice, a selection,[Pg 6] a progressive evolution, or, to sum up, in the survival of the individuals best adapted to the conditions of their existence. Without any intention of Dame Nature, the preservation of the species was necessarily, before anything else, the object of selection; and during the course of geological periods primitive bi-partition gradually became transformed through progressive differentiation into bi-sexual procreation, requiring the concurrence of special and complicated apparatus in order to be effected. But, at the same time as procreation, other functions also became differentiated by the formation of special organs; the nervous system vegetated around the chorda dorsalis; and, finally, conscious life awoke in the nervous centres. Thenceforth the accomplishment of the great function of procreation assumed an entirely different aspect. In the lowest stages of the animal kingdom reproduction is effected mechanically and unconsciously. A paramœcium, observed by M. Balbiani, produced in forty-two days, by a series of simple bi-partitions, 1,384,116 individuals, who very certainly had not the least notion of the phenomena by which they transmitted existence. But with superior animals it is very different; in their case the act of procreation is a real efflorescence, not only physical, but psychical. For the study that I am now undertaking it will not be without use to recall the principal features of this amorous efflorescence, since it is, after all, the first cause of marriage and of the family. At the same time, not to lose our standpoint, it is important to bear in mind that at the bottom all this expenditure of physical and psychical force has for motive and for result, both in man and animal, the conjugation of two generative cellules. Haeckel has written a dithyramb on this subject in his Anthropogenia, which is in the main so true that I take pleasure in quoting it—“Great effects are everywhere produced, in animated nature, by minute causes.... Think of how many curious phenomena sexual selection gives rise to in animal life; think of the results of love in human life; now, all this has for its raison d’être the union of two cellules.... There is no organic act which approaches this one in power and in the force of differentiation. The Semitic myth of Eve seducing Adam for the love of knowledge, the old Greek[Pg 7] legend of Paris and Helen, and many other magnificent poems, do they not simply express the enormous influence that sexual love and sexual selection have exercised since the separation of the sexes? The influence of all the other passions which agitate the human heart cannot weigh in the balance with love, which inflames the senses and fascinates the reason. On the one hand, we celebrate in love the source of the most sublime works of art, and of the noblest creations of poetry and of music; we venerate it as the most powerful factor in civilisation, as the prime cause of family life, and consequently of social life. On the other hand, we fear love as a destructive flame; it is love that drives so many to ruin; it is love that has caused more misery, vice, and crime than all other calamities together. Love is so prodigious, its influence is so enormous on psychic life and the most diverse functions of the nervous system, that in regard to it we are tempted to question the supernatural effect of our natural explanation. Nevertheless, comparative biology and the history of development conduct us surely and incontestably to the simplest, most remote source of love; that is to say, the elective affinity of two different cellules—the spermatic cell and the ovulary cell.”[1]
