  The problem that has apparently not been solved by the earlier two critiques is that of showing that our choice to act in accordance with the moral law, as the fundamental principle of all laws of freedom, a choice that can be free only if it is conceived of as taking place in a “supersensible” or noumenal realm that is not governed by the deterministic laws of “sensible” or phenomenal nature, where every event is fully determined by chains of causality extending far back beyond any particular choice of any particular individual, must nevertheless be efficacious within that phenomenal world, able to transform the natural world into a “moral world” where people really do act in accordance with the moral law and the ends that are imposed upon us by that law really can be realized. And the reason for linking aesthetic and teleological judgment together in a third critique apparently must be that these two forms of human experience and judgment together somehow offer a solution to this problem.
