Most philosophers now accept that an agent may be responsible for an action even though she could not have acted otherwise. However, many who accept such a view about responsibility for actions nevertheless maintain that, when it comes to omissions, an agent is responsible only if she could have done what she omitted to do. If this Principle of Possible Action (PPA), as it is sometimes called, is correct, then there is an important asymmetry between what is required for responsibility for actions and what is required for responsibility for omissions. However, I argue here that PPA is in fact false. It has been advanced on the basis of an insufficiently varied group of examples. Examination of a broader range of cases shows that responsibility for an omission sometimes is, and it sometimes is not, undermined by an inability to have acted. In Sections II and III, I offer two alternative principles to PPA governing ability and responsibility for omissions.

This paper examines libertarian accounts that appeal to event causation but avoid appeal to agent causation. Such views are modest in their metaphysical commitments and may be modest, as well, in what they promise. It is argued that an action-centered version should be preferred; on such a view, indeterminism is required in the direct production of decision or other action. Although a view of this kind does not improve on compatibilist accounts when it comes to moral responsibility, they may be preferable in other respects.

This paper examines the libertarian account of free choice advanced by Robert Kane in his recent book, The Significance of Free Will. First a rather simple libertarian view is considered, and an objection is raised against it the view fails to provide for any greater degree of agent-control than what could be available in a deterministic world. The basic differences between this simple view and Kane's account are the requirements, on the latter, of efforts of will and of an agent's wanting more to do a certain thing than he wants to do anything else. It is argued here that neither of these features yields any improvement over the simple libertarian view; neither helps to meet the objection that was raised against the simple view. Finally, it is suggested that a modest defense of that view might be available.

A contrastive rational explanation of a choice cites a reason why the agent made that choice rather than, say, making a different choice, or rather than making no choice at all. It is often said that if, as libertarians maintain, free choices are undetermined by prior events, then it is not possible to provide contrastive rational explanations of them. Alternatively, it is sometimes said that while non-causal contrastive rational explanation of such a choice might be possible, causal contrastive rational explanation is not. Here it is argued that the libertarian requirement is no bar to causal contrastive rational explanation of free choice.

This paper addresses an argument from Richard Double to the effect that any libertarian account of free will must attribute to human action a kind of rationality that is impossible. Double's argument relies on an alleged principle of rational explanation. Here it is argued that the proposed principle is false, and hence that Double has failed to show that libertarianism has any problem with rationality. The paper concludes with a suggestion as to how the sort of rationality in question is made possible.

Frankfurt-style cases are supposed to show that an agent can be responsible for doing something even though the agent wasn’t able to do otherwise. Neil Levy has argued that the cases fail. Agents in such cases, he says, lack a capacity that they’d have to have in order to be responsible for doing what they do. Here it’s argued that Levy is mistaken. Although it may be that agents in Frankfurt-style cases lack some kind of capability, what they lack isn’t required for them to be responsible for doing what they do. Differences between actions and omissions, and between the requirements for responsibility for these two, are also discussed.

Philosophical theories of agency have focused primarily on actions and activities. But, besides acting, we often omit to do or refrain from doing certain things. How is this aspect of our agency to be conceived? This book offers a comprehensive account of omitting and refraining, addressing issues ranging from the nature of agency and moral responsibility to the metaphysics of absences and causation. Topics addressed include the role of intention in intentional omission, the connection between negligence and omission, the distinction between doing and allowing, and the distinction in law between act and omission.
