To understand Kant’s attitude fully, we must also take into consideration the great weight that he attaches to the Moral Argument for the existence of God. The positive side of his teaching on Theism is summed up in the following sentence (p. 388): “For the theoretical reflective Judgement physical Teleology sufficiently proves from the purposes of Nature an intelligent world-cause; for the practical Judgement moral Teleology establishes it by the concept of a final purpose, which it is forced to ascribe to creation.” That side of his system which is akin to Agnosticism finds expression in his determined refusal to admit anything more than this. The existence of God is for him a “thing of faith”; and is not a fact of knowledge, strictly so called. “Faith” he holds (p. 409) “is the moral attitude of Reason as to belief in that which is unattainable by theoretical cognition. It is therefore the constant principle of the mind to assume as true that which it is necessary to presuppose as condition of the possibility of the highest moral final purpose.” As he says elsewhere (Introduction to Logic, ix. p. 60), “That man is morally _unbelieving_ who does not accept that which, though _impossible_ to know, is _morally necessary_ to suppose.” And as far as he goes a Theist may agree with him, and he has done yeoman’s service to Theism by his insistence on the absolute impossibility of any other working hypothesis as an explanation of the phenomena of nature. But I have endeavoured to indicate at what points he does not seem to me to have gone as far as even his own declared principles would justify him in going. If the existence of a Supreme Mind be a “thing of faith,” this may with equal justice be said of the finite minds of the men all around us; and his attempt to show that the argument from analogy is here without foundation is not convincing.
