 There are serious difficulties at issue in this scholarly dispute. But Kant’s line of thought in the long passage just quoted is relatively clear: We all (most of us) recognize that there are situations where we ought to do something, even though it will cost us something that is very dear to us (i.e., we feel ourselves subject to an unconditional moral imperative). So far as we really acknowledge this “ought,” we commit ourselves to believing that it will be possible for us to do this (i.e., that we are free). This reveals something that we could hardly be certain of except on the basis of this encounter with our own activity of moral reasoning (cf. Kleingeld 2010).
