The new dispositionalists defend the position that an agent in a deterministic Frankfurt-style case (FSC) has the ability to do otherwise, where that ability is the one at issue in the principle of alternative possibilities. Focusing specifically on Kadri Vihvelin’s proposal, I argue against this position by showing that it is incompatible with the existence of structurally similar cases to FSCs in which a preemptive intervener bestows an agent with an ability.

According to the libertarian view of free will, people sometimes act freely, but this freedom is incompatible with causal determinism. Goetz (1997, 1998, 2008) has developed an important and unusual libertarian view of free will. Rather than simply arguing that a person’s free actions cannot be causally determined,Goetz argues that they cannot be caused at all. According to Goetz, in order for a person to act freely, her actions must be uncaused. My aim in this essay is to evaluate Goetz’s “noncausal” libertarian view of free will. In section 1, I outline Goetz’s view. In section 2, I develop two criticisms of his view. In section 3, I develop an improved “positive” account of the noncausal view, which takes Goetz’s metaphysical framework as its point of departure but is not subject to the criticisms that plague his development of this framework. Finally, in section 4, I respond to some objections to my proposed noncausal view.

Moral wrongness comes in degrees. On a consequentialist view of ethics, the wrongness of an act should depend, I argue, in part on how much worse the act’s consequences are compared with those of its alternatives and in part on how difficult it is to perform the alternatives with better consequences. I extend act consequentialism to take this into account, and I defend three conditions on consequentialist theories. The first is consequentialist dominance, which says that, if an act has better consequences than some alternative act, then it is not more wrong than the alternative act. The second is consequentialist supervenience, which says that, if two acts have equally good consequences in a situation, then they have the same deontic status in the situation. And the third is consequentialist continuity, which says that, for every act and for any difference in wrongness δ greater than zero, there is an arbitrarily small improvement of the consequences of the act which would, other things being equal, not change the wrongness of that act or any alternative by more than δ. I defend a proposal that satisfies these conditions.

Graham Priest defends the use of a nonmonotonic logic, LPm, in his analysis of reasoning in the face of true contradictions, such as those arising from the paradoxes of self-reference. In the course of defending this choice of logic in the face of the criticism that this logic is not truth preserving, Priest argued (2012) that requirement is too much to ask: since LPm is a nonmonotonic logic, it necessarily fails to preserve truth. In this article, I show that this assumption is incorrect, and I explain why nonmonotonic logics can nonetheless be truth preserving. Finally, I diagnose Priest’s error, to explain when nonmonotonic logics do indeed fail to preserve truth.

According to Originalism, word types are non-eternal continuants which are individuated by their causal-historical lineage and have a unique possible time of origination. This view collides with the intuition that individual words can be added to the lexicon of a language at different times, and generates other problematic consequences. The paper shows that such undesired results can be accommodated without abandoning Originalism.

Expressivists and relativists about epistemic modals often motivate their view by arguing against contextualist treatments of certain cases. However, I argue that even expressivists and relativists should consider being a kind of contextualist. Specifically, data involving mixed disjunctions motivate taking epistemic modals to be sensitive to contextually-salient partitions, and thus context-sensitive.

The accessibility relation between possible worlds can be defined in the metalanguage of counterfactual semantics. As a result, counterfactuals can ground the whole of standard modal logic.

The essentially comparative conception of value entails that the value of a state of affairs does not depend solely upon features intrinsic to the state of affairs, but also upon extrinsic features, such as the set of feasible alternatives. It has been argued that this conception of value gives us reason to abandon the transitivity of the better than relation. This paper shows that the support for intransitivity derived from this conception of value is very limited. On its most plausible interpretations, it merely provides a necessary, but not sufficient, condition for intransitivity. It is further argued that the essentially comparative conception of value appears to support a disjunctive conclusion: there is incommensurability of value or betterness is not transitive. Of these two alternatives, incommensurability is preferable, because it is far less threatening to our other axiological commitments.

Michael Ridge argues that metaethical expressivism can avoid its most worrisome problems by going ‘Ecumenical’. Ridge emphasizes that he aims to develop expressivism at the level of metasemantics rather than at the level of (first-order) semantics. This is supposed to allow him to avoid a mentalist semantics of attitudes and instead offer an orthodox, truth-conditional or propositional semantics. However, I argue that Ridge’s theory remains committed to mentalist semantics, and that his move to go metasemantic doesn’t bring any clear advantages to the debate between expressivism and its opponents.

This paper raises a challenge to Jonathan Schaffer’s priority monism. I contend that monism may be true at the actual world but fail to hold as a matter of metaphysical necessity, contrary to Schaffer’s view that monism, if true, is necessarily true. My argument challenges Schaffer for his reliance on contingent physical truths in an argument for a metaphysically necessary conclusion. A counterexample in which the actual laws of physics hold but the physical history of the universe is different shows that priority monism is contingently true at best. I suggest some general lessons for discussion of metaphysical dependence.

The Paradox of the Surprise Examination has been a testing ground for a variety of frameworks in formal epistemology, from epistemic logic to probability theory to game theory and more. In this paper, I treat a related paradox, the Paradox of the Undiscoverable Position (from Sorensen 1982, 1988), as a test case for the possible-worlds style representation of epistemic states. I argue that the paradox can be solved in this framework, further illustrating the power of possible-worlds style modeling. The solution also illustrates an important distinction between anti-performatory and unassimilable announcements of information.

The aim of this study is to address the “Grounding Grounding Problem,” that is, the question as to what, if anything, grounds facts about grounding. I aim to show that, if a seemingly plausible principle of modal recombination between fundamental facts and the principle customarily called “Entailment” are assumed, it is possible to prove not only that grounding facts featuring fundamental, contingent grounds are derivative but also that either they are (at least) partially grounded in the grounds they feature or they are “abysses” (i.e., derivative facts without fundamental grounds and lying at the top of an infinitely descending chain of ground).

Skepticism about the ‘wrong kind’ of reasons—the view that wrong-kind reasons are reasons to want and bring about certain attitudes, but not reasons for those attitudes—is more often assumed than argued for. Jonathan Way (2012) sets out to remedy this: he argues that skeptics about, but not defenders of, wrong-kind reasons can explain a distinctive pattern of transmission among such reasons and claims that this fact lends significant support to the skeptical view. I argue that Way’s positive case for wrong-kind reason skepticism fails. I conclude with an account of what’s needed to resolve the debate between wrong-kind reason skeptics and defenders.

The focus of this article is the question whether the notion of being in a position to know is closed under modus ponens. The question is answered negatively.

Making sense of our reasoning in disputes about necessary truths requires admitting nonvacuous counterpossibles. One class of these is the counteressentials, which ask us to make contrary to fact (and therefore contrary to possibility) suppositions about essences. A popular strategy in accounting for nonvacuous counterpossibles is to extend the standard possible worlds semantics for subjunctive conditionals by the addition of impossible worlds. A conditional A □→ C is then taken to be true if all of the nearest A worlds (whether possible or impossible) are C worlds. I argue that a straightforward extension of the standard possible worlds semantics to impossible worlds does not result in a viable account of counteressentials and propose an alternative covering law semantics for counteressentials.

A classic objection to act-consequentialism is that it is overdemanding: it requires agents to bear too many costs for the sake of promoting the impersonal good. I develop the complementary objection that act-consequentialism is underdemanding: it fails to acknowledge that agents have moral reasons to bear certain costs themselves, evenwhen itwould be impersonally better for others to bear these costs.
