Nagel's Absolute Idealism

On p. 17 he identifies his position as objective idealist, and includes the post-Kantians Schelling and Hegel as representatives of his view, which are usually called absolute idealists. This is reminiscent of C. S. Lewis, who, once he became persuaded of the correctness of his Argument from Reason against naturalism, became, not a theist, but a Hegelian Absolute Idealists. His reason for avoiding theism could easily be described in Nagelian terms as a cosmic authority problem. Of course, Lewis eventually rejected Absolute Idealism in favor of first theism and then finally Christianity, while Nagel, of course, has not done this.
