Peter van Inwagen's Direct Argument (DA) purports to establish the incompatibility of determinism and moral responsibility, without appealing to the notion of avoidability, a notion on whose analysis compatibilists and incompatibilists disagree. Van Inwagen intended DA to refute compatibilism, or at least to shift the burden of proof onto the compatibilist. In this paper, we offer a critical assessment of DA. We examine a variety of objections to DA due to John Fischer and Mark Ravizza, Ishtiyaque Haji, Seth Shabo, Michael McKenna, and David Widerker. We divide these objections into those based on dialectical considerations (section 1), and objections in the form of counterexamples to a central principle which the Direct Argument employs (sec 2). The conclusion we reach is that the proponent of DA can deal plausibly with these objections, thus establishing DA as a powerful argument in favor of incompatibilism.

Pereboom’s defense of deliberation-compatibilism is the most elaborate and most sophisticated current attempt to defend this position. In this paper, I have provided a careful, and open-minded assessment of that defense. The conclusion that emerged is that it is subject to an important objection that leaves him with no explanation of the relevant difference between a scenario in which it would irrational for an agent to deliberate what to do, and a scenario the deliberation-compatibilist would consider appropriate for rational deliberation. Without a satisfactory response to this objection, Pereboom’s defense of deliberation-compatibilism cannot be deemed successful.

Recently, Colin McGinn has argued that Kripke's Cartesian argument against the mind-body identity thesis is not effective against anomalous monism. This paper attempts to show that the Cartesian has at his disposal an argument that is stronger than that formulated by Kripke, and one that cannot be rebutted by the anomalous monist in the way suggested by McGinn. The paper concludes with a suggestion as to the sort of identity theory one would have to subscribe to in order to resist the stronger Cartesian argument.

Elsewhere, I proposed a libertarian-based account of freedom and moral blameworthiness which like Harry Frankfurt's 1969 account rejects the principle of alternative possibilities (which I call, Frankfurt-friendly libertarianism). In this paper I develop this account further (a) by responding to an important objection to it raised by Carlos Moya; (b) by exploring the question why, if unavoidability per se does not exonerate from blame, the Frankfurt-friendly libertarian is justified in exculpating an agent under determinism; (c) by arguing that some main compatibilist alternatives to the account are unsatisfactory; and finally (d) by defending it against a general criticism of certain libertarian theories made by Derk Pereboom

Recently, John Fischer has applied Frankfurt’s well-known counter-example to the principle of alternate possibilities to refute the traditional libertarian position which holds that a necessary condition for an agent’s decision (choice) to be free in the sense of freedom required for moral responsibility is that the decision not be causally determined, and that the agent could have avoided making it. Fischer’s argument has consequently led various philosophers to develop libertarian accounts of freedom which try to dispense with the avoidability constraint on freedom. My purpose in this article is to show that Fischer’s attack on traditional libertarianism fails, and, therefore, it is premature to abandon that 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.

Recently, Colin McGinn has argued that Kripke's Cartesian argument against the mind-body identity thesis is not effective against anomalous monism. This paper attempts to show that the Cartesian has at his disposal an argument that is stronger than that formulated by Kripke, and one that cannot be rebutted by the anomalous monist in the way suggested by McGinn. The paper concludes with a suggestion as to the sort of identity theory one would have to subscribe to in order to resist the stronger Cartesian argument.

John Fischer has attacked the Ockhamistic solution to the freedom–foreknowledge dilemma by arguing that: (1) God's prior beliefs about the future, though being soft facts about the past, are soft facts of a special sort, what he calls ‘hard-type soft facts’, i.e. soft facts, the constitutive properties of which are ‘hard’, or ‘temporally non-relational properties’; (2) in this respect, such facts are like regular past facts which are subject to the fixity of the past. In this paper, I take issue with this argument by Fischer, claiming that it does not succeed for two reasons: (i) Fischer's account of the notion of a hard property is unsatisfactory; (ii) his notion of a hard-type soft fact is incoherent. Despite this criticism, I agree with Fischer that there is a fundamental difference between God's beliefs about the future and regular soft facts with regard to their fixity-status, but I argue that the reason for this difference is that God's forebeliefs are plain hard facts about the past.

Non-Causal Libertarianism (NCL) is a libertarian position which aims to provide a non-causal account of action and freedom to do otherwise. NCL has been recently criticized from a number of quarters, notably from proponents of free will skepticism and agent-causation. The main complaint that has been voiced against NCL is that it does not provide a plausible account of an agent’s control over her action, and therefore, the account of free action it offers is inadequate. Some critics (mainly agent-causationists) have even gone so far as to claim that NCL does not offer a plausible account of action. My goal in this paper is to defend NCL against these charges. More specifically, I deal with Derk Pereboom's Disappearing-Agent-Objection, Peter van Inwagen's Mind Argument, and with two objections to NCL by Randolph Clarke.
