Many follow Kant in thinking that morally worthy actions must be carried out solely from the motive of duty. This outlook faces two challenges: (1) The One Feeling Too Few problem (actions that issue from, say, compassion also seem to have moral worth), and (2) The One Thought Too Many problem (some actions have moral worth precisely because they’re not motivated by duty). These challenges haven’t led Kantians to dispense with the motive of duty. Instead, they have proposed to push (...) it into the background. We should not (the thought goes) construe duty as a primary motive, a consideration that motivates the agent to act. Duty is best thought of as a secondary motive, a background concern that constrains her choice. Since it is consistent with acting from duty at the secondary level that one is motivated at the primary level by compassion, this move is thought to overcome both challenges. In this paper, I argue that secondary motive views don’t live up to their stated ambitions. Such proposals either fail to make progress on issues with which primary motive views continue to grapple, or they render the motive of duty ill-suited to underwrite a plausible account of moral worth.
