That is to say, Kant’s supposed advance upon earlier forms of philosophy is found merely in the fact that he has combined an abstract rationalism such as that of Parmenides or Spinoza with that of an equally abstract brute factualism such as that of the most extreme process philosophers of history. This is all that anyone who does not start his thinking on the presupposition of the God of Christianity and his revelation through Christ speaking in Scripture can do. All men do their thinking on the basis of a position accepted by faith. If your faith is not one which has God in Christ speaking infallibly in Scripture for its object, then your faith is in man as autonomous. All of one’s reasoning is controlled by either of these presuppositions.
. . . Only if one presupposes God as the one in whom rationality and being are coterminous and coextensive can he use the laws of logic at all. And if he does this, he knows better than to attempt to determine what is possible or impossible in reality by means of these laws. The Christian has a God whom he as a creature cannot fully comprehend. God says I am and is able to fully justify this assertion. He is able to make it stand because only on the basis of this assertion does the thinking and willing activity of man have any possible meaning at all. The Christian gladly accepts the idea that he cannot logically penetrate the idea of man’s responsibility and his place in the plan of God. But Kant has brought God as well as himself down into utter darkness. He has no foundation on which he can make any assertion stand.
