There is absolutely nothing in the constitution of nature, we may say, reversing Dr. Mozley's assertion, which does not prove the incredibility of a Divine suspension of physical laws, and does not create a presumption against it. There is no instance producible, or even logically conceivable, of any power whose effects are opposed to the ultimate ruling of the laws of nature. The occurrence of anything opposed to those laws is incredible. Dr. Mozley has himself shown that miracles cannot be explained either by unknown connection with known law, or by reference to unknown law; and he renounces the explanation of "higher law." His distinction between the laws of nature and the "laws of the universe,"(1) by which he nevertheless endeavours to make a miracle credible, is one which is purely imaginary, and cannot affect us in our present position within the order of nature. We know of no laws of the universe differing from the laws of nature. So far as human observation can range, these laws alone prevail. For all practical purposes, therefore, such a distinction is futile, and belief is necessarily limited to the actual operation of natural laws. The occasional intervention of an unknown "efficient cause," producing the effects {45} called "miracles"--effects which are not referrible to any known law--is totally opposed to experience, and such a hypothesis to explain alleged occurrences of a miraculous character cannot find a legitimate place within the order of nature. 2. The proposition with which Dr. Mozley commences these Bampton Lectures, and for which he contends to their close, is this: "That miracles, or visible suspensions of the order of nature for a providential purpose, are not in contradiction to reason."(1) He shows that, the purpose of miracles is to attest a supernatural revelation, which, without them, we could not be justified in believing. "Christianity," he distinctly states, "cannot be maintained as a revelation undiscoverable by human reason--a revelation of a supernatural scheme for man's salvation without the evidence of miracles."(2) Out of this very admission he attempts to construct an argument in support of miracles: "Hence it follows," he continues, "that upon the supposition of the Divine design of a revelation, a miracle is not an anomaly or irregularity, but part of the system of the universe; because, though an irregularity and an anomaly in relation to either part, it has a complete adaptation to the whole. There being two worlds, a visible and invisible, and a communication between the two being wanted, a miracle is the instrument of that communication."(3) Here, again, the argument is based upon mere assumption. {46}
