"Science then Shall be a precious visitant; and then, And only then, be worthy of her name; For then her heart shall kindle, her dull eye, Dull and inanimate, no more shall hang Chained to its object in brute slavery; But taught with patient interest to watch The process of things, and serve the cause Of order and distinctness, not for this Shall it forget that its most noble use, Its most illustrious province, must be found In furnishing clear guidance, a support, Not treacherous, to the mind's _excursive_ power."[20]
But the gift of Science to Theology shall be not less rich. With the inspiration of Nature to illuminate what the inspiration of Revelation has left obscure, heresy in certain whole departments shall become impossible. With the demonstration of the naturalness of the supernatural, scepticism even may come to be regarded as unscientific. And those who have wrestled long for a few bare truths to ennoble life and rest their souls in thinking of the future will not be left in doubt.
It is impossible to believe that the amazing succession of revelations in the domain of Nature during the last few centuries, at which the world has all but grown tired wondering, are to yield nothing for the higher life. If the development of doctrine is to have any meaning for the future, Theology must draw upon the further revelation of the seen for the further revelation of the unseen. It need, and can, add nothing to fact; but as the vision of Newton rested on a clearer and richer world than that of Plato, so, though seeing the same things in the Spiritual World as our fathers, we may see them clearer and richer. With the work of the centuries upon it, the mental eye is a finer instrument, and demands a more ordered world. Had the revelation of Law been given sooner, it had been unintelligible. Revelation never volunteers anything that man could discover for himself--on the principle, probably, that it is only when he is capable of discovering it that he is capable of appreciating it. Besides, children do not need Laws, except Laws in the sense of commandments. They repose with simplicity on authority, and ask no questions. But there comes a time, as the world reaches its manhood, when they will ask questions, and stake, moreover, everything on the answers. That time is now. Hence we must exhibit our doctrines, not lying athwart the lines of the world's thinking, in a place reserved, and therefore shunned, for the Great Exception; but in their kinship to all truth and in their Law-relation to the whole of Nature. This is, indeed, simply following out the system of teaching begun by Christ Himself. And what is the search for spiritual truth in the Laws of Nature but an attempt to utter the parables which have been hid so long in the world around without a preacher, and to tell men at once more that the Kingdom of Heaven is like unto this and to that?
