If the removal of suspicion from Theology is of urgent moment, not less important is the removal of its adulterations. These suspicions, many of them at least, are new; in a sense they mark progress. But the adulterations are the artificial accumulations of centuries of uncontrolled speculation. They are the necessary result of the old method and the warrant for its revision--they mark the impossibility of progress without the guiding and restraining hand of Law. The felt exhaustion of the former method, the want of corroboration for the old evidence, the protest of reason against the monstrous overgrowths which conceal the real lines of truth, these summon us to the search for a surer and more scientific system. With truths of the theological order, with dogmas which often depend for their existence on a particular exegesis, with propositions which rest for their evidence upon a balance of probabilities, or upon the weight of authority; with doctrines which every age and nation may make or unmake, which each sect may tamper with, and which even the individual may modify for himself, a second court of appeal has become an imperative necessity.
Science, therefore, may yet have to be called upon to arbitrate at some points between conflicting creeds. And while there are some departments of Theology where its jurisdiction cannot be sought, there are others in which Nature may yet have to define the contents as well as the limits of belief.
What I would desire especially is a thoughtful consideration of the method. The applications ventured upon here may be successful or unsuccessful. But they would more than satisfy me if they suggested a method to others whose less clumsy hands might work it out more profitably. For I am convinced of the fertility of such a method at the present time. It is recognized by all that the younger and abler minds of this age find the most serious difficulty in accepting or retaining the ordinary forms or belief. Especially is this true of those whose culture is scientific. And the reason is palpable. No man can study modern Science without a change coming over his view of truth. What impresses him about Nature is its solidity. He is there standing upon actual things, among fixed laws. And the integrity of the scientific method so seizes him that all other forms of truth begins to appear comparatively unstable. He did not know before that any form of truth could so hold him; and the immediate effect is to lessen his interest in all that stands on other bases. This he feels in spite of himself; he struggles against it in vain; and he finds perhaps to his alarm that he is drifting fast into what looks at first like pure Positivism. This is an inevitable result of the scientific training. It is quite erroneous to suppose that science ever overthrows Faith, if by that is implied that any natural truth can oppose successfully any single spiritual truth. Science cannot overthrow Faith; but it shakes it. Its own doctrines, grounded in Nature, are so certain, that the truths of Religion, resting to most men on Authority, are felt to be strangely insecure. The difficulty, therefore, which men of Science feel about Religion is real and inevitable, and in so far as Doubt is a conscientious tribute to the inviolability of Nature it is entitled to respect.
None but those who have passed through it can appreciate the radical nature of the change wrought by Science in the whole mental attitude of its disciples. What they really cry out for in Religion is a new standpoint--a standpoint like their own. The one hope, therefore, for Science is more Science. Again, to quote Bacon--we shall hear enough from the moderns by-and-by--"This I dare affirm in knowledge of Nature, that a little natural philosophy, and the first entrance into it, doth dispose the opinion to atheism; but, on the other side, much natural philosophy, and wading deep into it, will bring about men's minds to religion."[2]
