But be it so. Fear is a natural passion, and a wholesome one. Without the instinct of self-preservation, which causes the sea-anemone to contract its tentacles, or the fish to dash into its hover, species would be extermined wholesale by involuntary suicide.

Yes; fear is wholesome enough, like all other faculties, as long as it is controlled by reason. But what if the fear be not rational, but irrational? What if it be, in plain homely English, blind fear; fear of the unknown, simply because it is unknown? Is it not likely, then, to be afraid of the wrong object? to be hurtful, ruinous to animals as well as to man? Any one will confess that, who has ever seen, a horse inflict on himself mortal injuries, in his frantic attempts to escape from a quite imaginary danger. I have good reasons for believing that not only animals here and there, but whole flocks and swarms of them, are often destroyed, even in the wild state, by mistaken fear; by such panics, for instance, as cause a whole herd of buffaloes to rush over a bluff, and be dashed to pieces. And remark that this capacity of panic, fear—of superstition, as I should call it—is greatest in those animals, the dog and the horse for instance, which have the most rapid and vivid fancy. Does not the unlettered Highlander say all that I want to say, when he attributes to his dog and his horse, on the strength of these very manifestations of fear, the capacity of seeing ghosts and fairies before he can see them himself?

But blind fear not only causes evil to the coward himself: it makes him a source of evil to others; for it is the cruellest of all human states. It transforms the man into the likeness of the cat, who, when she is caught in a trap, or shut up in a room, has too low an intellect to understand that you wish to release her: and, in the madness of terror, bites and tears at the hand which tries to do her good. Yes; very cruel is blind fear. When a man dreads he knows not what, he will do he cares not what. When he dreads desperately, he will act desperately. When he dreads beyond all reason, he will behave beyond all reason. He has no law of guidance left, save the lowest selfishness. No law of guidance: and yet his intellect, left unguided, may be rapid and acute enough to lead him into terrible follies. Infinitely more imaginative than the lowest animals, he is for that very reason capable of being infinitely more foolish, more cowardly, more superstitious. He can—what the lower animals, happily for them, cannot—organise his folly; erect his superstitions into a science; and create a whole mythology out of his blind fear of the unknown. And when he has done that—Woe to the weak! For when he has reduced his superstition to a science, then he will reduce his cruelty to a science likewise, and write books like the “Malleus Maleficarum,” and the rest of the witch literature of the fifteenth, sixteenth, and seventeenth centuries; of which Mr. Lecky has of late told the world so much, and told it most faithfully and most fairly.

But, fear of the unknown? Is not that fear of the unseen world? And is not that fear of the spiritual world? Pardon me: a great deal of that fear—all of it, indeed, which is superstition—is simply not fear of the spiritual, but of the material; and of nothing else.

The spiritual world—I beg you to fix this in your minds—is not merely an invisible world which may become visible, but an invisible world which is by its essence invisible; a moral world, a world of right and wrong. And spiritual fear—which is one of the noblest of all affections, as bodily fear is one of the basest—is, if properly defined, nothing less or more than the fear of doing wrong; of becoming a worse man.

But what has that to do with mere fear of the unseen? The fancy which conceives the fear is physical, not spiritual. Think for yourselves. What difference is there between a savage’s fear of a demon, and a hunter’s fear of a fall? The hunter sees a fence. He does not know what is on the other side, but he has seen fences like it with a great ditch on the other side, and suspects one here likewise. He has seen horses fall at such, and men hurt thereby. He pictures to himself his horse falling at that fence, himself rolling in the ditch, with possibly a broken limb; and he recoils from the picture he himself has made; and perhaps with very good reason. His picture may have its counterpart in fact; and he may break his leg. But his picture, like the previous pictures from which it was compounded, is simply a physical impression on the brain, just as much as those in dreams.

Now, does the fact of the ditch, the fall, and the broken leg, being unseen and unknown, make them a spiritual ditch, a spiritual fall, a spiritual broken leg? And does the fact of the demon and his doings, being as yet unseen and unknown, make them spiritual, or the harm that he may do, a spiritual harm? What does the savage fear? Lest the demon should appear; that is, become obvious to his physical senses, and produce an unpleasant physical effect on them. He fears lest the fiend should entice him into the bog, break the hand-bridge over the brook, turn into a horse and ride away with him, or jump out from behind a tree and wring his neck—tolerably hard physical facts, all of them; the children of physical fancy, regarded with physical dread. Even if the superstition proved true; even if the demon did appear; even if he wrung the traveller’s neck in sound earnest, there would be no more spiritual agency or phenomenon in the whole tragedy than there is in the parlour-table, when spiritual somethings make spiritual raps upon spiritual wood; and human beings, who are really spirits—and would to heaven they would remember that fact, and what it means—believe that anything has happened beyond a clumsy juggler’s trick.

You demur? Do you not see that the demon, by the mere fact of having produced physical consequences, would have become himself a physical agent, a member of physical Nature, and therefore to be explained, he and his doings, by physical laws? If you do not see that conclusion at first sight, think over it till you do.

It may seem to some that I have founded my theory on a very narrow basis; that I am building up an inverted pyramid; or that, considering the numberless, complex, fantastic shapes which superstition has assumed, bodily fear is too simple to explain them all.

But if those persons will think a second time, they must agree that my base is as broad as the phenomena which it explains; for every man is capable of fear. And they will see, too, that the cause of superstition must be something like fear, which is common to all men: for all, at least as children, are capable of superstition; and that it must be something which, like fear, is of a most simple, rudimentary, barbaric kind; for the lowest savage, of whatever he is not capable, is still superstitious, often to a very ugly degree. Superstition seems, indeed, to be, next to the making of stone-weapons, the earliest method of asserting his superiority to the brutes which has occurred to that utterly abnormal and fantastic lusus naturæ called man.
