 According to Kant, what is singular about motivation by duty is that it consists of bare respect for the moral law. What naturally comes to mind is this: Duties are rules or laws of some sort combined with some sort of felt constraint or incentive on our choices, whether from external coercion by others or from our own powers of reason. For instance, the bylaws of a club lay down duties for its officers and enforce them with sanctions. City and state laws establish the duties of citizens and enforce them with coercive legal power. Thus, if we do something because it is our “civic” duty, or our duty “as a boy scout” or “a good American,” our motivation is respect for the code that makes it our duty. Thinking we are duty bound is simply respecting, as such, certain laws pertaining to us.
