And the God he postulates is brought in ex machina like the God of the old Design argument in its roughest popular form.
Here he postulates force and mind as emanating from original matter - a materialistic monism.
This modification was the beginning of a gradual lessening of the antithesis of a priori to a posteriori, until at last the a priori forms of Kant have been transmuted into " auxiliary conceptions," or " postulates of experience."
At the same time, in spite of his sympathy with the whole development of idealism since Kant, which leads him to reject the thing in itself, to modify a priorism, and to stop at transcendent " ideals," without postulates of practical reason, he nevertheless has so much sympathy with Kant's Kritik as on its theories of sense and understanding to build up a system of phenomenalism, according to which knowledge begins and ends with ideas, and finally on its theory of pure reason to accord to reason a power of logically forming an " ideal " of God as ground of the moral " ideal " of humanity - though without any power of logically inferring any corresponding reality.
Kant swept away, so far as his influence extended, such " dogmatic metaphysics " and the old-fashioned theism which it constituted or included; but Kant himself introduced, in his own more sceptical yet also more moral type of theistic doctrine, a new trichotomy - God, Freedom, Immortality, the three " postulates " of the practical reason."
