A groundswell of recent work in philosophy has sought to revitalize the analysis of causation by appealing to "active principles" such as powers, dispositions, capacities, tendencies, and propensities. These principles are described in a realist and rather Aristotelian fashion, in stark contrast to the deflationary and linguistic accounts of such principles characteristic of Humean thought and empiricist thinking more generally. Natures, essences, powers, and de re necessity are back in the analysis of causation. I do not argue in this paper (...) for the plausibility of the revitalization project in general; instead, I explain how I think one aspect of it must be understood if the project is to be plausible. I suggest that those who are moved to resist Humean austerity and embrace a realism about things such as causal powers should take care in how they formulate this realism. Some Aristotelian notions, such as the concept of a causal power, may well be useful to modern studies of causation. Others, such as the notion that causal powers are determined by essences which comprise the natures of things, are outmoded in many sciences today. This paper focuses specifically on the notions of power and essence in the context of causation. Contra some of the most important recent proponents of the revitalization project, I contend that causal generalizations are not generally best understood as determined by the essential properties of natural kinds. How a member of a kind (natural or otherwise) behaves causally may be a function of its causal powers, but such powers need not constitute anything like the "essence" of a kind. -/- 1.

It is my view that one essential difference between persons and other creatures is to be found in the structure of a person's will. Besides wanting and choosing and being moved to do this or that, men may also want to have certain desires and motives. They are capable of wanting to be different, in their preferences and purposes, from what they are. Many animals appear to have the capacity for what I shall call "first-order desires" or "desires of the (...) first order," which are simply desires to do or not to do one thing or another. No animal other than man, however, appears to have the capacity for reflective self-evaluation that is manifested in the formation of second-order desires. (shrink)

This essay challenges the widely accepted principle that a person is morally responsible for what he has done only if he could have done otherwise. The author considers situations in which there are sufficient conditions for a certain choice or action to be performed by someone, So that it is impossible for the person to choose or to do otherwise, But in which these conditions do not in any way bring it about that the person chooses or acts as he (...) does. In such situations the person may well be morally responsible for what he chooses or does despite his inability to choose or to do otherwise. Finally the author considers certain suggestions for revising the principle he rejects or for replacing it with a principle of an altogether different kind. (shrink)

In this essay I shall begin by sketching a "Frankfurt-type example." I shall then lay out a disturbing challenge to the claim I have made above that these examples help us to make significant progress in the debates about the relationship between moral responsibility and causal determinism. I then will provide a reply to this challenge, and the reply will point toward a more refined formulation of the important contribution I believe Frankfurt has made to defending a certain sort of (...) compatibilism.

In the subsequent pages, I want to develop a distinction between wanting and valuing which will enable the familiar view of freedom to make sense of the notion of an unfree action. The contention will be that, in the case of actions that are unfree, the agent is unable to get what he most wants, or values, and this inability is due to his own "motivational system." In this case the obstruction to the action that he most wants to do (...) is his own will. It is in this respect that the action is unfree: the agent is obstructed in and by the very performance of the action. (shrink)

Source incompatibilism is an increasingly popular version of incompatibilism about determinism and moral responsibility. However, many self-described source incompatibilists formulate the thesis differently, resulting in conceptual confusion that can obscure the relationship between source incompatibilism and other views in the neighborhood. In this paper I canvas various formulations of the thesis in the literature and argue in favor of one as the least likely to lead to conceptual confusion. It turns out that accepting my formulation has some surprising taxonomical consequences.

In ‘Alternate Possibilities and Moral Responsibility,’ Harry Frankfurt introduces a scenario aimed at showing that the having of alternative possibilities is not required for moral responsibility. According to the Principle of Alternative Possibilities (PAP), an agent is morally responsible for her action only if she could have done otherwise; Frankfurt thinks his scenario shows that PAP is, in fact, false. Frankfurt thinks that the denial of PAP gives credence to compatibilism, the thesis that an agent could both be causally determined (...) in all her actions and yet be morally responsible.1 Since its introduction, Frankfurt’s original ex-.

The present essay is about this problem of the intelligibility of incompatibilist freedom. I do not think Kant, Nagel and Strawson are right in thinking that incompatibilist theories cannot be made intelligible to theoretical reason, nor are those many others right who think that incompatibilist accounts of freedom must be essentially mysterious or terminally obscure. I doubt if I can say enough in one short paper to convince anyone of these claims who is not already persuaded. But I hope to (...) persuade some readers that new ways of thinking about the problem are necessary and, more to the point, that new ways of thinking about the problem are possible. As Nagel says, "nothing approaching the truth has yet been said on this subject." Parts V and VI of this paper present one new way of thinking about the problem. Parts II through IV prepare for this way by distinguishing and discussing two kinds of incompatibilist theories. (shrink)

This essay examines several varieties of libertarian accounts of free will. Some require free actions to be uncaused, some require agent causation, and some require non-deterministic event causation. Difficulties are raised for all of these varieties.
