Reason, say both, is Faith's natural enemy; and must fail to yield any expectation of future happiness in the presence of a righteous God, together with its long train of present hopes and fears. Our plain answer is that the true synthesis of Natural Theism lies in the chief primary fact of our human nature—the undeniable existence of its Reasonable Beliefs. They originate deep down, and we may affirm respecting the birth of each and all, as Dr. Tyndall affirms of the inward vision which dawns upon the philosophic mind when photographically cleansed by its own efforts to think rightly,—"how this light arises we cannot explain, but as a matter of fact it does arise." In its degree it may be (to use Dr. Tyndall's word) "a kind of inspiration." And what endowment has a higher claim to such a representative kinship?—what nobler gift can be conceived from God to man than a Belief of Reason? Dr. Tyndall's further requirement that "the inward sight must be shown to be in accordance with the outward fact," a Natural Theologian may hope to meet by a sufficient verification. He may meet it in the case of this particular Belief by showing, as we shall try to show, our actual human experience of its working and its worth.
We might pursue similar examples through the regions of Discovery and Production, but the three instances already adduced may fairly suffice. It is, perhaps, more interesting to observe the real gains which accrue from pondering over an idea in the manner exemplified. How much political charlatanerie is at once disposed of when men distinctly acknowledge that two reputed incompatibilities, however useful as war-cries, are essentially conjoint elements in all truly statesmanlike action: what countless angry controversies die in the moral principle that each righteous man is a Law unto himself! And not only to Natural Theology, but to other parts of knowledge, it is of the greatest utility to perceive with equal distinctness that Reason has its beliefs as well as Unreason; and that when we accept reasonable beliefs as the basis of scientific investigation, we affirm their value for the conduct and government of life. The true amount of that value as a mainspring of our hopeful activities is estimated on another page. Meantime, we may remark from the three examples above discussed, how regularly an idea of Reason, analysed into its complementary factors, resumes a concrete form when we employ it as a maxim of practical life. The politician who separates progress from stability is really preparing his country for revolution. The man on whose heart the law is not written (like the necessity laid upon St. Paul[12]) is as yet imperfectly righteous. And so too, if in our Beliefs we lose sight of the gift that makes us human, we are likely to ring the changes between superstition, atheism, and effeminate sentimentality.
When, from results, we pass to the easiest method for attaining them, there seems but little to add to the extracts with which this note commenced. And if the object be clearly defined, the labour of the mental workshop need not be a severe discouragement. It is true that no man can take his Thought—the offspring of his inward Light—pull it to pieces, and reconstruct it, as he would deal with a thing of brass or iron. But every earnest ponderer may keep his prolific idea steadily in view, and hold conversations with himself respecting it. This is the well-known method by which Aristotle virtually obtains his conclusions before he finally proceeds to deduce them. From the same conception of Method, real thinking appears to Plato as a Dialogue without speech. And, doubtless, actual discussion between two or more living men would be the surest way of arriving at the goal of insight, provided those most uncommon of all endowments, common sense and common honesty, could be assured to the dialecticians.[13]
Thus much, then, may serve as an illustration of the task we are attempting, and of the means by which we hope to accomplish it. If achieved, it will form a contribution to the great work thus characterised by the Rector of Lincoln College from the University pulpit, as reported in the Oxford Undergraduates' Journal for October 26, 1871: "The Natural Theology of the last century is no longer found to be satisfactory in presence of the geological and biological sciences as they now stand. The answer that the sciences are wrong and the theologians are right does not admit of being discussed or refuted, for it is the answer of ignorance. The answer of the Catholic Church, which is to take refuge in its own authority, can only be practically tendered where there is an infallible living authority, as in the chair of S. Peter. It seems to be the business of the English Church especially—a Church which has never yet broken with reason or proscribed education—to fairly face these questions, to resume the Natural Theology of the past age, and to re-establish the synthesis of Science and Faith."
E.—ON THE EFFECT OF CONSILIENT PROOFS.
The expressive word "Consilience" has been adopted on the authority of Dr. Whewell and Professor Pritchard, both of whom employ it in preference to the commoner expression convergence. Upon the force of consilient proofs, Dr. Whewell writes thus:—
"The cases in which inductions from classes of facts altogether different have jumped together, belong only to the best established theories which the history of science contains. And as I shall have occasion to refer to this peculiar feature in their evidence, I will take the liberty of describing it by a particular phrase, and will term it the Consilience of Inductions.
"It is exemplified principally in some of the greatest discoveries. Thus it was found by Newton that the doctrine of the attraction of the sun varying according to the inverse square of the distance, which explained Kepler's Third Law of the proportionality of the cubes of the distances to the squares of the periodic times of the planets, explained also his First and Second Laws of the elliptical motion of each planet; although no connexion of these laws had been visible before. Again, it appeared that the force of universal gravitation, which had been inferred from the perturbations of the moon and planets by the sun and by each other, also accounted for the fact, apparently altogether dissimilar and remote, of the precession of the equinoxes. Here was a most striking and surprising coincidence, which gave to the theory a stamp of truth beyond the power of ingenuity to counterfeit....
... The theory of universal gravitation, and of the undulatory theory of light, are indeed full of examples of this consilience of inductions. With regard to the latter, it has been justly asserted by Herschel, that the history of the undulatory theory was a succession of felicities. And it is precisely the unexpected coincidences of results drawn from distant parts of the subject which are properly thus described." ("Philosophy of the Inductive Sciences," B. XI., chap. v., s. 3.)
