There is another fallacy running through all these pretended sciences--from phrenology and phreno-mesmerism to the most stupid exhibitions that have been ever given, under the names of "electrical psychology" and "mental alchemy." It is that view which, in effect, wholly denies any thing like a spiritual unity to the human soul, making it a series of separate impulses, or, like the keys of a piano, each when struck from without giving an isolated sound. Let one be touched, the machine lifts up its hand, and is supposed to pray. Strike another, and it blasphemes. And so, by turns, it hates and loves, and fears and trusts--not different objects, which would be perfectly consistent with a spiritual unity, in which the whole moral and intellectual state is represented in every exercise, but the same objects, and with transitions so sudden as to be almost simultaneous. We might, in a similar way, expose the absurd reasoning contained in all this, but we would rather dwell at present on the moral aspect of the case--the shocking irreverence it manifests toward the human soul, making its faith, its reason, its love, its conscience, as worthless as the lowest bodily appetites--sinking it, indeed, below the dignity of respectable organic or inorganic matter, with which such tricks can not be played, and reducing all that have heretofore been regarded as the highest moral truths to the rank of physical phenomena. In some former remarks of our Editorial Table, there was an allusion to the revolting claim clairvoyance makes to meddle with the soul's sacred individuality. The thought is applicable to all those kindred pretensions which are now so rife. Their tendency is to destroy all reverence for our own spirituality, and with it all reverence for the truly spiritual every-where. If this be true of what is called biology and mental alchemy, in a still more impressive sense may it be charged upon that other compound of blasphemy and Satanic mummery, which has grown directly out of them. We allude to the pretense of holding intercourse with departed spirits through mesmerized mediums, or what are usually called _spiritual rappings_. The first class of performances are an insult to the human intelligence; this is a moral outrage upon the most tender, the most solemn, the most religious feelings of our nature. The one is a profane trifling with all that is most sacred in life--the other is a violation of the grave, and of all beyond, of which it is the appointed vail. It is hard to write or speak with calmness here. The mischief done and doing in this direction, defies all proper estimate. These proceedings are sending lunatics to our asylums, but this is by no means the sorest evil that may be laid to their charge. It is the soul-hardening familiarity they are every where producing with the most awful subjects that can be offered for human contemplation. Such an effect, too, in relation to the spirit of man must soon be
