In Manipulated Agents: A Window to Moral Responsibility, Alfred Mele invokes radical reversal cases in which one agent is covertly manipulated to be just like another agent in relevant respects to defend a version of the following “externalist” thesis: how agents acquire their springs of action, such as desires and beliefs, bears on whether they are morally responsible for their actions. I assess proposed rationales for the crucial verdict that agents in such cases are not responsible for their germane actions. (...) I argue for the superiority of Mele’s rationale and propose that these cases also support accepting an externalist constraint on other normative appraisals, such as those of practical rationality. Key words: Moral obligation; practical rationality; radical reversal cases; ultimate origination; zygote argument. (shrink)

I argue that, each of the following, appropriately clarified to yield a noteworthy thesis, is true. Moral obligation can affect moral responsibility. Obligation succumbs to changes in responsibility. Obligation is immune from changes in responsibility.

Haji argues that determinism threatens deontic morality, not via a threat to moral responsibility, but directly, because of the principle that ‘ought’ implies ‘can’. Haji’s argument requires not only that we embrace an ‘ought’ implies ‘can’ principle, but also that we adopt the principle that ‘ought’ implies ‘able not to’. I argue that we have little reason to adopt the latter principle, and examine whether deontic morality might be destroyed on the basis of the more commonly embraced ‘ought’ implies ‘can’ (...) principle alone. I argue that despite what look like initially compelling reasons why we might suppose that this weaker conclusion is similarly destructive to deontic morality, we actually have good reason to doubt that it has any practical relevance for moral deliberation at all.
