In a recent paper, John Fischer develops a new argument against the Principle of Alternative Possibilities (PAP) based on a deterministic scenario. Fischer uses this result (i) to rebut the Dilemma Defense - a well-known incompatibilist response to Frankfurt-type counterexamples to PAP; and (ii) to maintain that: If causal determinism rules out moral responsibility, it is not just in virtue of eliminating alternative possibilities. In this article, we argue that Fischer's new argument against PAP fails, thus leaving points (i) and (ii) unsupported

In a recent article, David Hunt has proposed a theological counterexample to the principle of alternative possibilities involving divine foreknowledge (G-scenario). Hunt claims that this example is immune to my criticism of regular Frankfurt-type counterexamples to that principle, as God’s foreknowing an agent’s act does not causally determine that act. Furthermore, he claims that the considerations which support the claim that the agent is morally responsible for his act in a Frankfurt-type scenario also hold in a G-scenario. In reply, Icontest Hunt’s symmetry claim and also raise a worry whether, given theological fatalism, the agent’s act in a G-scenario can be deemed a free act in the libertarian sense. Finally, I offer an independent argument why in a G-scenario the agent should not regarded morally blameworthy for his act.

Abstract Libertarians typically believe that we are morally responsible for the choices (or decisions) we make only if those choices are free, and our choices are free only if they are neither caused nor nomically necessitated by antecedent events. Recently, there have been a number of attempts by philosophers to refute libertarianism by arguing that because a libertarianly free decision (choice) is both causally and nomically undetermined, which decision an agent makes in a deliberative situation is a matter of luck, which implies (due to the way these philosophers use 'luck') that the agent does not have control over which decision he makes. This argument has been dubbed "the Argument from Luck" or "the Luck Objection" against libertarianism – henceforth 'LO'. In this paper, we examine some versions of LO as reflected in the works of Alfred Mele (2006), Neil Levy (2011), and Peter van Inwagen (2000, 2011). We argue that libertarians have nothing to fear from LO. Deep down the objection reflects a failure, on the part of its proponents, really to come to grips with the libertarian position.

In this paper, I present an argument that shows that the belief in libertarian freedom is inconsistent with two assumptions widely accepted by those who are physicalists with regard to the relation between the mental and the physical - that mental properties are distinct from physical properties, and that mental properties supervene on physical properties. After presenting the argument, I trace its implications for the question of the compatibility of libertarian free will and physicalism in general.
