In the same sense that every thing may be said to be a mystery, so also may it be said that every thing is a miracle, and that no one thing is a greater miracle than another. The elephant, though larger, is not a greater miracle than a mite: nor a mountain a greater miracle than an atom. To an almighty power it is no more difficult to make the one than the other, and no more difficult to make a million of worlds than to make one. Every thing, therefore, is a miracle, in one sense; whilst, in the other sense, there is no such thing as a miracle. It is a miracle when compared to our power, and to our comprehension. It is not a miracle compared to the power that performs it. But as nothing in this description conveys the idea that is affixed to the word miracle, it is necessary to carry the inquiry further. Mankind have conceived to themselves certain laws, by which what they call nature is supposed to act; and that a miracle is something contrary to the operation and effect of those laws. But unless we know the whole extent of those laws, and of what are commonly called the powers of nature, we are not able to judge whether any thing that may appear to us wonderful or miraculous, be within, or be beyond, or be contrary to, her natural power of acting. The ascension of a man several miles high into the air, would have everything in it that constitutes the idea of a miracle, if it were not known that a species of air can be generated several times lighter than the common atmospheric air, and yet possess elasticity enough to prevent the balloon, in which that light air is inclosed, from being compressed into as many times less bulk, by the common air that surrounds it. In like manner, extracting flashes or sparks of fire from the human body, as visibly as from a steel struck with a flint, and causing iron or steel to move without any visible agent, would also give the idea of a miracle, if we were not acquainted with electricity and magnetism; so also would many other experiments in natural philosophy, to those who are not acquainted with the subject. The restoring persons to life who are to appearance dead as is practised upon drowned persons, would also be a miracle, if it were not known that animation is capable of being suspended without being extinct. Besides these, there are performances by slight of hand, and by persons acting in concert, that have a miraculous appearance, which, when known, are thought nothing of. And, besides these, there are mechanical and optical deceptions. There is now an exhibition in Paris of ghosts or spectres, which, though it is not imposed upon the spectators as a fact, has an astonishing appearance. As, therefore, we know not the extent to which either nature or art can go, there is no criterion to determine what a miracle is; and mankind, in giving credit to appearances, under the idea of their being miracles, are subject to be continually imposed upon.
