I have challenged the theology of Mr Darwin, and those who follow his guidance in theology. I have no wish to dispute his science. I pass no judgment on his theories so far as they are scientific theories. It may be safely left to the progress of scientific research to determine how far they are true and how far erroneous. We ought not to assail them needlessly, or to reject the truth which is in them, under the influence of a senseless dread that they can hurt religion. In so far as they are true, they must be merely expressions of the way in which Divine intelligence has operated in the universe. Instead of excluding, they must imply belief in an all-originating, all-foreseeing, all-foreordaining, all-regulative intelligence, to determine the rise and the course and the goal of life, as of all finite things. That intelligence far transcends the comprehension of our finite minds, yet we apprehend it as true intelligence. It is no blind force, but a Reason which knows itself, and knows us, and knows all things, and in the wisdom of which we may fully confide, even when clouds and darkness hide from us the definite reasons of its operations. We can see and know enough of its wisdom to justify faith where sight and knowledge are denied to us. Let us trust and follow it, and, without doubt, it will lead us by a path which we knew not, and make darkness light before us, and crooked things straight. LECTURE VII. MORAL ARGUMENT--TESTIMONY OF CONSCIENCE AND HISTORY. I. WE have seen how the power manifest in the universe leads up to God as the First Cause, the all-originating Will. We have seen also how the order manifest in the universe leads up to Him as the Supreme Intelligence. But there is more in the universe than force and order; there is force which works for good, and a just and benevolent order; there are moral laws and moral actions, moral perceptions and moral feelings. Can anything be thence inferred as to whether God is, and what He is? I think we shall find that they clearly testify both as to His existence and character.
