I therefore do not wish to call such duties 'duties to ourselves,' which is what they are customarily called, but rather mediate and conditioned duties: 'mediate' or 'indirect' mittelbare because they have as their object the means for all our efficacious acting; 'conditioned' bedingt because they can be derived only from the following proposition: if the moral law wills something that is conditioned (namely, the realization through me of thedominion of reason outside of me), then it also wills the condition (namely, that I be a fit and capable means for this end).
