Kant abolished God and made man God in His stead. We are still living in the age of the Kantian man, or Kantian man-god. Kant's conclusive exposure of the so-called proofs of the existence of God, his analysis of the limitations of speculative reason, together with his eloquent portrayal of the dgnity of rational man, has had results which might possibly dismay him. How recognizable, how familiar to us, is the man so beautifully portrayed in the Grundelgung, who confronted even with Christ turns away to consider the judgment of his own conscience and to hear the voice of his own reason. Stripped of the exiguous metaphysical background which Kant was prepared to allow him, this man is with us still, free, independent, lonely, powerful, rational, responsible, brave, the hero of so many novels and books of moral philosophy. The raison d'etre of this attractive but misleading creature is not far to seek. He is the offspring of the age of science, confidently rational and yet increasingly aware of his alienation from the material universe which his discoveries reveal; and since he is not a Hegelian (Kant, not Hegel, has provided Western ethics with its dominating image) his alienation is without cure. He is the ideal citizen of the liberal state, a warning held up to tyrants. He has the virtue which the age requires and admires, courage. It is not such a very long step from Kant to Nietzsche, and from Nietzsche to existentialism and the Anglo-Saxon ethical doctrines which in some ways closely resemble it. In fact Kant's man had already received a glorious incarnation nearly a century earlier in the work of Milton: his proper name is Lucifer.
