The notion of a miracle, considered as a proof of a divine mission, has been stated with great exactness by divines; and is, I think, sufficiently understood by every one. There are also invisible miracles,[162] the Incarnation of Christ, for instance, which, being secret, cannot be alleged as a proof of such a mission; but require themselves to be proved by visible miracles. Revelation itself too is miraculous; and miracles are the proof of it; and the supposed presumption against these shall presently be considered. All which I have been observing here is, that, whether we choose to call every thing in the dispensations of Providence, not discoverable without revelation, nor like the known course of things, miraculous; and whether the general Christian dispensation now mentioned is to be called so, or not; the foregoing observations seem certainly to show, that there is no presumption against it from the analogy of nature. II. There is no presumption, from analogy, against some operations, which we should now call miraculous; particularly none against a revelation at the beginning of the world: nothing of such presumption against it, as is supposed to be implied or expressed in the word, _miraculous_.[163] A miracle, in its very notion, is relative to a course of nature; and implies something different from it, considered as being so. Now, either there was no course of nature at the time which we are speaking of; or if there were, we are not acquainted what the course of nature is, upon the first peopling of worlds. Therefore the question, whether mankind had a revelation made to them at _that_ time, is to be considered, not as a question concerning a miracle, but as a common question of fact. And we have the like reason, be it more or less, to admit the report of tradition, concerning this question, and concerning common matters of fact of the same antiquity; for instance, what part of the earth was first peopled. Or thus: When mankind was first placed in this state, there was a power exerted, totally different from the present course of nature. Now, whether this power, thus wholly different from the present course of nature, (for we cannot properly apply to it the word _miraculous_;) whether this power _stopped_ immediately after it had made man, or went on, and exerted itself further in giving him a revelation, is a question of the same kind, as whether an ordinary power exerted itself in such a particular _degree_ and manner, or not.
