It is in this qualifying clause that Kant’s negative attitude in respect of Theism betrays itself. He regards it as a necessary assumption for the guidance of scientific investigation, no less than for the practical needs of morals; but he does not admit that we can claim for it objective validity. In the language of the Critique of Pure Reason, the Idea of God furnishes a regulative, not a constitutive principle of Reason; or as he prefers to put it in the present work, it is valid only for the reflective, not for the determinant Judgement. We are not justified, Kant maintains, in asserting dogmatically that God exists; there is only permitted to us the limited formula “We cannot otherwise conceive the purposiveness which must lie at the basis of our cognition of the internal possibility of many natural things, than by representing it and the world in general as produced by an intelligent cause, _i.e._ a God” (p. 312). We ask then, whence arises this impossibility of objective statement? It is in the true Kantian spirit to assert that no synthetical proposition can be made with reference to what lies above and behind the world of sense; but there is a difficulty in carrying out this principle into details. Kant’s refusal to infer a designing Hand behind the apparent order of nature is based, he tells us, on the fact that the concept of a “natural purpose” is one that cannot be justified to the speculative Reason. For all we know it may only indicate our way of looking at things, and may point to no corresponding objective reality. That we are forced by the limited nature of our faculties to view nature as working towards ends, as purposive, does not prove that it is really so. We cannot justify such pretended insight into what is behind the veil.
