There exists the further problem of the origin of spirits that have never been mortal. These must come somehow from somewhere, and there is no reason to suppose that the continuation of sex upon the astral planes is not for this purpose. Its existence is indeed an absolute answer to the theories of parthenogenesis held by believers whose minds were clouded with a residuum of theological beliefs. To sum up, we have evidence of the continuation of sex--indeed it is a cardinal point, for it is impossible to believe in continuation of personality after death unless sex continues with it. One cannot logically believe in the one without the other. The state of error has arisen through the confusion of sex with sin. The would-be formulators of the new Spiritualistic dogmas, having been unable to effect a mental compromise between the moral and monogamous Christian and the moral and polygamous Mohammedan, attempted to solve the whole business by a bland statement that there was no sex in the other world. Some writers do indeed recognize this permanence of sex, but gloss it over.[22] They ignore the fact that if a thing exists it exists for a purpose and the fatal conception that the gratification of a sex desire is a sin persists throughout their pages. On the other hand, gratification of other voluptuous sense desires such as aural pleasures from music or self-abandonment to any of the pleasures of the intellect, appears to be regarded not only as permissible but as praise-worthy. In fact, any analysis of the reported habits and customs of the next world, plunges us into a mass of paradoxical contradictions. In point of fact it is impossible to draw a hard-and-fast line between the actual spirit revelation and interpolated ideas by the medium. It is also notorious that as soon as any new concept of the next world is published in book form, the “revelations” from any different sources seem to take on an unmistakable tinge according to the latest theories. In fact, a literary psychoanalysis of reported next worlds shows the unmistakable traces of books read in the past. Certain accounts of the spirit life obtained through Mohammedan mediums by French investigators in Algiers show what may be called a peculiarly active sexual life in the after-world. This may possibly be attributed to either early religious belief in a sensuous Mohammedan paradise or alternatively to the particular type of Arab spirits who furnished the description. In any case, the accounts could not be published for general or even private reading, but there is no conceivable reason why they should be deemed more unreliable than other spirit communications.
