theoretical reflective Judgement we should say: if we have ground for assuming for the purposive products of nature a supreme Cause of nature — whose causality in respect of the actuality of creation is of a different kind from that required for the mechanism of nature, i.e. must be thought as the causality of an Understanding — we have also sufficient ground for thinking in this original Being not merely the purposes everywhere in nature but also a final purpose. This is not indeed a final purpose by which we can explain the presence of such a Being, but one of which we may at least convince ourselves (as was the case in physical Teleology) that we can make the possibility of such a world conceivable, not merely according to purposes, but only through the fact that we ascribe to its existence a final purpose.
