A positive sexual philosopher of a nobler kind than these two anomalous spirits is Max Zeiss, whose book, “Ragnarök, a Philosophico-Social Study,” was published at Strasburg in 1904. He regards work, effort, creation, the strife for material position, for honour and renown, only as subordinate aims for the attainment of one aim—love.

The ever more intimate association of love with the spiritual life, its increasing depth, the inclusion within its sphere of influence of all feelings and thoughts, necessarily give rise to a stronger development of the feeling of individual personality, which, in contrast with the earlier instinctive impulse, came more and more to dominate the amatory life. Now love gained at least an equal importance for the individual that in former conditions it had for the purposes of reproduction, and therewith subjectively the reproductive idea was unquestionably thrust into the background, in comparison with the idea of personal living, of personal enrichment and development, by means of love. Hegel says aptly (“Æsthetics,” Berlin, 1837, vol. ii., p. 186): “The sorrows of love, these frustrate hopes, the very state of being in love, the never-ending pains which the lover actually experiences, this never-ending happiness and joy to which he looks forward in imagination—these are matters devoid of all general interest; they concern only the lover himself.” Schleiermacher also insists, in his letters concerning “Lucinde,” on the great importance of love for the spiritual development of the individual.

The individualization of love has certainly resulted in a great decline in the predominance of the reproductive idea, of the subjective sense of race, without it ever being possible for it to lose its eminent objective significance. Nietzsche, therefore, declares a “reproductive impulse” to be pure “mythology;”[38] and Carpenter, also, in his book, “Love’s Coming of Age,” says that human love is mainly a desire for complete union, and only in much less degree a wish for the reproduction of the race. The profound significance of individual love in the promotion of civilization is exceedingly well described by him when he says:

“Taking union as the main point, we may look upon the idealized sex-love as a sense of contact pervading the whole mind and body—while the sex-organs are a specialization of this faculty of union in the outermost sphere: union in the bodily sphere giving rise to bodily generation, the same as union in the mental and emotional spheres occasions generation of another kind.”

Proof of the fact that love, in its purely individual relations, is also of great importance for human civilization, that it is profoundly significant for the higher evolution of humanity, in addition to its importance for the perpetuation of the species—the proof of this thesis is very important in view of certain problems connected with the theory of population and in view of the practical conclusions deduced from that theory, as, for example, the doctrine of neo-malthusianism. Love and love’s embrace do not exist only for the purposes of the species: they are also of importance to the ego; they are necessary for the life, the evolution, and the internal growth of the individual himself.

And we must not fail to recognize to what extent the fact that the individual has gained much from love ultimately reacts also to the advantage of the species. For the species, as well as for the individual, the true path of progress lies in the direction of the individualization of the sexual impulses.

When we study in detail the gradual permeation of sexuality with spiritual elements, the gradual development of love, and its advance towards perfection by means of civilization, we ascertain that for the love of the modern civilized man there exists a kind of biogenetic, or rather psychogenetic, fundamental law. In modern love we encounter all the spiritual elements which were actively operative in the love of past times; the love of the civilized man of the present day is an extracted, shortened, compressed repetition of the entire developmental course of love from the earliest times to the present day. And the general course of this development reappears also in the love of the individual.

This course is, to put the matter shortly, from the general to the individual, from the remote to the proximate. We can further divide the history of human love into two great epochs. In the first epoch, love was, above all, a transcendental relationship of a religio-metaphysical nature. The transcendental relationships played a more important part than the purely human and personal. Everywhere an ulterior element played its part. In the second epoch, love underwent an evolution into a more personal relationship, in which the human being himself took foremost place, as compared with any transcendental considerations. The history of love is, in fact, an illustration of Compte’s replacement of the theologico-metaphysical epoch of mental development by the anthropological. In individual love, however, there still remain active and demonstrable many transcendental elements. The oldest spiritual elements of love continue to form a portion of the content of modern love, and to play a more or less dominant part in its genesis.

To this primeval and psychical phenomenon belongs, above all, an intimate association between religious ideas and feelings and the sexual life. In a certain sense, the history of religion can be regarded as the history of a peculiar mode of manifestation of the human sexual impulse, especially in its influence on the imagination and its products.

Certain modern writers, members of the laity far from learned in the history of civilization, have considered the Roman Catholic Church pre-eminently responsible for the appearance of this sexual element in ritual and dogma. This, however, is grossly unjust. A scientific study of these relations teaches us that all religions exhibit to a greater or less degree this sexual admixture, and if this appears more prominent in the Roman Catholic Church, it is due, in the first place, to the fact that this religion is nearer to us in time than many of the religions of antiquity, and, in the second place, it is explicable on the ground that the Roman Catholic Church has always displayed greater openness and less hypocrisy than, for example, the Protestant pietists, who, as the Königsberg scandal, the Eva van Buttler affair, etc., show, are no less blameworthy in respect of sexual vagaries.
