Nevertheless, I am not at all of opinion that we must definitely reject the spiritualistic theory; that would be both unjust and premature. Hitherto everything remains in suspense. We may say that things are still very little removed from the point marked by Sir William Crookes, in 1874, in an article which he contributed to the “Quarterly Journal of Science.” He there wrote: The difference between the advocates of Psychic Force and the Spiritualists consists in this--that we contend that there is as yet insufficient proof of any other directing agent than the Intelligence of the Medium, and no proof whatever of the agency of Spirits of the Dead; while the Spiritualists hold it as a faith, not demanding further proof, that Spirits of the Dead are the sole agents in the production of all the phenomena. Thus the controversy resolves itself into a pure question of _fact_, only to be determined by a laborious and long-continued series of experiments and an extensive collection of psychological _facts_, which should be the first duty of the Psychological Society, the formation of which is now in progress. HAS THE SPIRIT ONLY AN INCOHERENT MEMORY OF LIFE? Meanwhile, it is saying a good deal that rigorous scientific investigations have not utterly shattered a theory which radically confounds the idea which we were wont to form of death. We shall see presently why, in considering our destinies beyond the grave, we need have no reason to linger too long over these apparitions or these revelations, even though they should really be incontestable and to the point. They would seem, all told, to be only the incoherent and precarious manifestations of a transitory state. They would at best prove, if we were bound to admit them, that a reflection of ourselves, an after-vibration of the nerves, a bundle of emotions, a spiritual silhouette, a grotesque and forlorn image, or, more correctly, a sort of truncated and uprooted memory, can, after our death, linger and float in a space where nothing remains to feed it, where it gradually becomes wan and lifeless, but where a special fluid, emanating from an exceptional medium, succeeds at moments in galvanizing it. Perhaps it exists objectively, perhaps it subsists and revives only in the recollection of certain sympathies. After all, it would be not unlikely that the memory which represents us during our life should continue to do so for a few weeks or even a few years after our decease. This would explain the evasive and deceptive character of those spirits which, possessing only a mnemonic existence, are naturally able to interest themselves only in matters within their reach. Hence their irritating and maniacal energy in clinging to the slightest facts, their sleepy dullness, their incomprehensible indifference and ignorance, and all the wretched absurdities which we have noticed more than once.
