The Philosophy of Mystery

by Walter Cooper Dendy

We must believe that each illusive representation is marked by some change in some certain portion of the brain, the function of which bears a reference to the subject or nature of the illusion: it may be so minute as not to be recognized by our vision. Indeed, if the bodily sensations of every human passion be faithfully analyzed, it will be proved that there is an unusual feeling in some part, when even a thought passes through the mind, under these definitions:—a thrill, a creeping, a glow, a flush, a chill, a tremor,—nay, even fainting, convulsion, death.

Now the brain feels, and thinks, and wills; but the blood is also essential to these faculties. If part of the brain is changed, or its circulation deranged, in that instant an effect unlike health is produced: and such is the illusion of the ghost-seer. Or if the substance of the organ of sense, as the eye, be altered, its function is deranged, and an illusive spectrum appears to float before it. Nay, we are assured by Tiedeman and Gall, (opinions of high value,) that they have known patients who (smile as you please) were mad only on one side of the brain, and perceived their madness with the other; and I may assure you, too, that there have been persons who really thought with half the brain only.

I will again claim the courtesy of these fair dames, while I offer another glimpse of the dull cold region of physiology.

Recollect the illustrations I have adduced in allusion to those classes, on whose privacy the ghost has the privilege of intrusion. I will now offer illustrations of those remote influences which work these seeming mysteries in the sensitive or diseased brain.

A patient of Dr. Gregory, at the hour of six, one hour after dinner, was daily visited by a hag, or incubus, which confronted him, and appeared to strike him with a crutch. Immediately on this he would fall from his chair in a swoon. This gentleman was relieved by bleeding and abstinence.

The Abbé Pilori, in Florence, invariably saw the phantom of scorpions around him, after he had partaken of luncheon.

There was a gentleman in Edinburgh, learned in fourteen languages, of the age of seventy-six. In 1819, he began to see strange faces, in old dresses, like paintings, and his own face changing from young to old; and these phantoms came at his call. Wine drinking increased especially these spectres, during the twelve years that the illusion continued; yet his mental faculties were not much impaired. When eighty years old, he came to London to dine with the Knights of the Bath, and went back at the rate of a hundred miles a-day. His language latterly was a patois of fourteen. One night he saw his dead wife’s shadow, and jumped after her out of the window, and ran after her through the conservatory; yet he remembered, when told that his wife was dead, and was then quiet. Disordered digestion aggravated his case extremely. Mr. Gragg’s opinion was, that “his thinking was correct, but the expression of thought wrong.” On examination, the dura mater was found adherent to the skull: in parts there was a thick effusion and vascularity over the brain, and the carotids were partially ossified.

In a mind excited or exhausted, the natural sympathy between the brain and the stomach is wrought up to an extreme. And in the two most interesting cases of spectral illusion on record, this instance is beautifully illustrated. The bookseller of Berlin, Nicolai (whose phantasms are become so hackneyed a tale in the records of Psychology), had been thus mentally excited. It were long to repeat the circumstantial and scientific detail of his waking visions: of his ghosts of departed friends, and of strangers to him, and of the groups of shadowy figures which glided through his chamber at these spectral levees; and how his philosophic mind distinguished the intrusion of the spectre at the door and the real friend to whom its opening gave admittance; and how they disappeared when he shut his eyes, and came again as he opened his lids; or how he was at last amused by his analysis of all these illusive spectra. But the sympathy to which I have alluded will be efficiently proved by one quotation from the Prussian’s recital. During the time leeches were applied to his temples, his chamber was crowded with phantoms. “This continued uninterruptedly till about half-past four o’clock, when my digestion commenced. I then fancied that they began to move more slowly: soon after, their colour began to fade, and at seven o’clock they were entirely white: then they seemed to dissolve in the air, while fragments of some of them continued visible a considerable time.” On other occasions, they attempted to re-appear, and changed to white, more and more faintly as his health improved.

There is equal interest, both for science and curiosity, in the illusion of Mrs. A. (as told by Brewster, in his “Natural Magic”), and which sprung from the like causes. The sympathetic sensitiveness of this lady was so acute, that an expression of pain in another produced it in the corresponding part of herself. And she, too, was intruded on by spectres of men and women, and cats and carriages, and by corpses in shrouds peering over her shoulder at her toilet-glass, and ghastly likenesses of gentlemen in grave-clothes, sitting unceremoniously in arm chairs in her drawing-room. And yet the perfect restoration of the lady’s health was coincident with her complete freedom from these spectral visitations.

You will read in the Anatomie of Melancholy, that “Eremites and anchorites have frequently such absurd visions and revelations, by reason of much fasting.” In exhaustion, too, or on the approach of vertigo, if we shut our eyes, we seem as if turning round ourselves, and if we open them, then this whimsical movement is referred to the chairs and tables in our chamber.
