I think the Platonic-Christian theology necessary to defend the moralistic position. Kant and the German idealists can’t do it, because their position, though subjective, is not humanistic; and the absolute self may turn pantheist or even materialist, or in the other direction, perfectly anarchical, as in Nietsche. But that theology seems to me an evident fiction, made to defend a moralistic prejudice.
