Now, as the ethical obligation to ends, of which there may be many, is only indetermi- nate, because it contains only a law for the maxim of actions, and the end is the matter (object) of           will; hence there are many duties, differing according to the difference of lawful ends, which may be called duties of virtue (officia honestatis), just because they are sub- ject only to free self-constraint, not to the constraint of other men, and determine the end which is also a duty.
