Mesmerism is high life below stairs; Momus playing Jove in the kitchens of Olympus. ’Tis a low curiosity or lust of structure, and is separated by celestial diameters from the love of spiritual truths. It is wholly a false view to couple these things in any manner with the religious nature and sentiment, and a most dangerous superstition to raise them to the lofty place of motives and sanctions. This is to prefer halos and rainbows to the sun and moon. These adepts have mistaken flatulency for inspiration. Were this drivel which they report as the voice of spirits really such, we must find out a more decisive suicide. I say to the table-rappers:-- “I well believe Thou wilt not utter what thou dost not know, And so far will I trust thee, gentle Kate.” They are ignorant of all that is healthy and useful to know, and by laws of kind,--dunces seeking dunces in the dark of what they call the spiritual world,--preferring snores and gastric noises to the voice of any muse. I think the rappings a new test, like blue litmus or other chemical absorbent, to try catechisms with. It detects organic skepticism in the very heads of the Church. ’Tis a lawless world. We have left the geometry, the compensation, and the conscience of the daily world, and come into the realm or chaos of chance and pretty or ugly confusion; no guilt and no virtue, but a droll bedlam, where everybody believes only after his humor, and the actors and spectators have no conscience or reflection, no police, no foot-rule, no sanity,--nothing but whim and whim creative. Meantime far be from me the impatience which cannot brook the supernatural, the vast; far be from me the lust of explaining away all which appeals to the imagination, and the great presentiments which haunt us. Willingly I too say, Hail! to the unknown awful powers which transcend the ken of the understanding. And the attraction which this topic has had for me and which induces me to unfold its parts before you is precisely because I think the numberless forms in which this superstition has re-appeared in every time and every people indicates the inextinguishableness of wonder in man; betrays his conviction that behind all your explanations is a vast and potent and living Nature, inexhaustible and sublime, which you cannot explain. He is sure no book, no man has told him all. He is sure the great Instinct, the circumambient soul which flows into him as into all, and is his life, has not been searched. He is sure that intimate relations subsist between his character and his fortunes, between him and his world; and until he can adequately tell them he will tell them wildly and fabulously. Demonology is the shadow of Theology.
