Of all founders of religions, Mohammed first proclaimed a divinity without relation to sex. One of his earliest suras reads: “He is God alone, God the eternal. He begetteth not, and is not begotten; And there is none like unto him.” And elsewhere:-- “He hath no spouse, neither hath he any offspring.”[71-1] While he expressly acknowledged the divine conception of Jesus, he denied the coarse and literal version of that doctrine in vogue among the ignorant Christians around him. Enlightened christendom, to-day, does not, I believe, differ from him on this point. Such sexual religions do not arise, as the theory has hitherto been, from study and observation of the generative agencies in nature, but from the identity of object between love in sense and love in intellect, profane and sacred passion. The essence of each is _continuance_, preservation; the origin of each is subjective, personal; but the former has its root in sensation, the latter in reason. The sex-difference in organisms, the “abhorrence of self-fertilization” which Mr. Darwin speaks of as so conspicuous and inexplicable a phenomenon, is but one example of the sway of a law which as action and reaction, thesis and antithesis, is common to both elementary motion and thought. The fertile and profound fancy of Greece delighted to prefigure this truth in significant symbols and myths. Love, Eros, is shown carrying the globe, or wielding the club of Hercules; he is the unknown spouse of Psyche, the soul; and from the primitive chaos he brings forth the ordered world, the Kosmos. The intimate and strange relation between sensuality and religion, so often commented upon and denied, again proven, and always misinterpreted, thus receives a satisfactory explanation. Some singular manifestations of it, of significance in religious history, are presented by the records of insane delusions. They confirm what I have above urged, that the association is not one derived from observation through intellectual processes, but is a consequence of physiological connections, of identity of aim in the distinct realms of thought and emotion. That eminent writer on mental diseases, Schroeder van der Kolk, when speaking of the forms of melancholy which arise from physical conditions, remarks: “The patient who is melancholy from disorders of the generative organs considers himself sinful. His depressed tone of mind passes over into religious melancholy; ‘he is forsaken by God; he is lost.’ All his afflictions have a religious color.” In a similar strain, Feuchtersleben says: “In the female sex especially, the erotic delusion, unknown to the patient herself, often assumes the color of the religious.”[73-1] “The unaccomplished sexual designs of nature,” observes a later author speaking of the effects of the single life, “lead to brooding over supposed miseries which suggest devotion and religious exercise as the nepenthe to soothe the morbid longings.”[73-2]
