According to the Principle of Alternative Possibilities, an agent is morally responsible for an action of hers only if she could have done otherwise. The notion of a robust alternative plays a prominent role in recent attacks on PAP based on so-called Frankfurt cases. In this paper I defend the truth of PAP for blameworthy actions against Frankfurt cases recently proposed by Derk Pereboom and David Widerker. My defence rests on some intuitively plausible principles that yield a new understanding of (...) the concept of a robust alternative. I will leave aside whether PAP also holds for praiseworthy actions -/- Según el Principio de Posibilidades Alternativas, un agente es moralmente responsable de una acción sólo si hubiera podido actuar de otro modo. La noción de alternativa robusta desempeña un papel prominente en ataques recientes al PPA basados en los llamados casos Frankfurt. En este artículo defiendo el PPA para la culpabilidad moral frente a casos Frankfurt propuestos recientemente por Derk Pereboom y David Widerker. Mi defensa descansa en algunos principios intuitivamente plausibles que dan lugar a una comprensión nueva del concepto de alternativa robusta. No trataré la cuestión de la verdad del PPA para acciones moralmente laudables. (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)

Harry g frankfurt gave what has been taken to be a counter-Example to the principle that, "a person is morally responsible for what he has done only if he could have done otherwise." I argue that in his case the agent cannot be morally responsible for what he did, Because it was not within his power not to be compelled to do it. So frankfurt's case is not a counter-Example to this principle.

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.

The Frankfurt cases have been thought by some philosophers to show that moral responsibility does not require genuine metaphysical access to alternative possibilities. But various philosophers have rejected this putative "lesson" of the cases, and they have put forward a powerful "Dilemma Defense." In the last decade or so, many philosophers have been persuaded by the Dilemma Defense that the Frankfurt cases do not show what Frankfurt (and others) thought they show. This essay presents a template for a general strategy (...) of response to the Dilemma Defense. It thus seeks to provide further support for the author's view that the Frankfurt cases help to establish that moral responsibility does not require alternative possibilities. (shrink)
