Praiseworthiness and Motivational Enhancement: 'No Pain, No Praise'?

The view that exertion of effort determines praiseworthiness for an achievement is implicit in 'no pain, no praise'-style objections to biomedical enhancement. On such views, if enhancements were to reduce the need for effort, agents would be less praiseworthy. Motivational enhancement would appear to be the most problematic in this respect, given that increased motivation reduces the need for agents to rally themselves and to exert effort in activity. We use the prospect of motivational enhancement to re-examine the grounds of praiseworthiness for achievements. We consider the place of effort amongst the grounds for praise, whether effort exhausts these grounds, and how they can be better specified. We argue that praiseworthiness depends on (i) the voluntariness and strength of the agent's committed pursuit of a valuable end (E), (ii) the costliness of the committed pursuit of E, and (iii) the value of E. Effort is just one cost amongst many, and costs of activities can be traded-off. Motivational enhancement reduces the praise due to an agent only when it reduces the net cost to the agent (without strengthening the voluntary commitment). We emphasize the importance of a diachronic perspective on active agency for praiseworthiness, to include training, prior planning, and deliberate strategies to overcome weakness of will, even where this reduces the need for effort.
