Albeit, then, between the realm of the natural concept, as the sensible, and the realm of the concept of freedom, as the supersensible, there is a great gulf fixed, so that it is not possible to pass from the former to the latter (by means of the theoretical employment of reason), just as if they were so many separate worlds, the first of which is powerless to exercise inﬂuence on the second: still the latter is meant to inﬂuence the former that is to say, the concept of freedom is meant to actualize in the sensible world the end proposed by its laws; and nature must consequently also be capable of being regarded in such a way that in the conformity to law of its form it at least harmonizes with the possibility of the ends to be effectuated in it according to the laws of freedom.
