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.
