Though again in the Transcendental Dialect he spoke of pure reason conceiving " ideals " of noumena, he did not mean that a noumenon is nothing but a thought arising only through thinking, or projected by reason, but meant that pure reason can only conceive the " ideal " while, over and above the " ideal " of pure reason, a noumenon is a real thing, a thing in itself, which is not indeed known, but whose existence is postulated by practical reason in the three instances of God, freedom, and immortality.
But it is not maintained, on the side either of phenomena or of noumena; and hence its tendency to materialism.
Or is it simply a reiteration of his sceptical contrast between phenomena and noumena, and of his confinement of (valid) knowledge to the former?
But they disagreed with Kant, and agreed with Fichte about things in themselves or noumena, and contended that the mental things we know are not mere phenomena of sense, but noumena, precisely because noumena are as mental as phenomena, and therefore can be known from similar data: this was the central point of their noumenal idealism.
Starting from Fichte's " Wissenschaftslehre," Schelling accepted the whole process of mental construction, and the deduction that noumena are knowable products of universal reason, the Absolute Ego.
