If, with Tyndall, we are to place man outside of nature, then the human mind at once becomes to us a supernatural intelligence. But truth forbids such a conclusion. The reason of man, however beyond the intelligence of lower animals, so harmonizes with natural laws that it is evidently a part of the great unity of nature, and we can no more dissociate the mind of man from nature than from his own animal body. If we could do so, we might have ground to distrust the validity of all our conclusions as to nature, and thus to cut away the foundations of science; and what remained of philosophy and religion would be preternatural, in the bad sense of destroying the unity of nature and imperilling our confidence in the unity of the Creator himself.
In connection with this we have cause to consider the true meaning and use of two terms often hurled at theists as weapons of attack.
The word "anthropomorphic" is a term of reproach for our interpreting nature in harmony with our own thoughts or our own constitution. But if man is a part of nature, he must be a competent interpreter of it. If he is not a part of nature, then, whether we make him godlike or a demon, we have, in him, to deal with something supernatural. It is true that in a certain sense he is above nature, but not in any sense which so dissociates him from it as to prevent him from rationally thinking of it in his own thoughts and speaking of it in his own form of words. So true is this that no writers are more anthropomorphic in their modes of speaking of nature than those who most strongly denounce anthropomorphism. Even the celebrated definition of life by Herbert Spencer cannot escape this tincture. "Life," he says, "is the continuous adjustment of internal to external conditions." Now, the essence of this definition lies in the word "adjustment." But to adjust is to arrange, adapt, or fit--all purely human and intelligent actions. Nothing, therefore, could be more anthropomorphic than such a statement. As theists we need not complain of this, but surely as agnostics we should decidedly object to it.
The other word whose meaning it is necessary to consider is "supernatural," which it might be well, perhaps, to follow the example of the New Testament in avoiding altogether as a misleading term. If by supernatural we mean something outside of and above nature and natural law, there is really no such thing in the universe. There may be that which is "spiritual," as distinguished from that which is natural in the material sense; but the spiritual has its own laws, which are not in conflict with those of the natural. Even God cannot in this sense be said to be supernatural, since his will is necessarily in conformity with natural law. Yet this absurd sense of the term "supernatural" is constantly forced upon us by so-called advanced thinkers, and employed as an argument against theism. The only true sense in which any being or any thing can be said to be supernatural is that in which we use it with reference to the original creation of matter and force and the institution of natural law. The power which can do these things is above nature, but not outside of it; for matter, energy, and law must be included in, and in harmony with, the Creative Will.
