The wave function of quantum mechanics can be understood in terms of the dispositional role it plays in the dynamics of a distribution of matter in three-dimensional space (or four-dimensional spacetime). There is more than one way, however, of specifying its dispositional role. This paper considers Suárez’s theory of ‘Bohmian dispositionalism’, in which the particles are endowed with their own ‘Bohmian dispositions’, and Simpson’s theory of ‘Cosmic Hylomorphism’, in which the particle configuration comprises a hylomorphic substance which has an intrinsic power. I argue that Bohmian dispositionalism fails to capture intuitively correct counterfactuals about what would happen in Small Worlds which have only a small number of particles, but that this problem is avoided by Cosmic Hylomorphism, in which the cosmic power manifests a teleological process.

Uniqueness appears to enhance intrinsic value. A unique stamp sells for millions of dollars; Stradivarius violins are all the more precious because they are unlike any others. This observation has not gone overlooked in the value theory literature: uniqueness plays a starring role recalibrating the dominant Moorean understanding of the nature of intrinsic value. But the thesis that uniqueness enhances intrinsic value is in tension with another deeply plausible and widely held thesis, namely the thesis that there is a pro tanto reason to promote the good. It is argued that there is a second, distinct type of uniqueness that plays a more interesting and important axiological role: uniqueness imparts irreplaceable value. This gives occasion to develop the surprisingly undertheorized notion of irreplaceable value.

Suppose two players wish to divide a finite set of indivisible items, over which each distributes a specified number of points. Assuming the utility of a player’s bundle is the sum of the points it assigns to the items it contains, we analyze what divisions are fair. We show that if there is an envy-free (EF) allocation of the items, two other desirable properties—Pareto-optimality (PO) and Maximinality (MM)—can also be satisfied, rendering these three properties compatible. But there may be no EF division, in which case some division must satisfy a modification of Bentham’s (1789/2017) “greatest satisfaction of the greatest number” property, called maximum Nash welfare (MNW), that satisfies PO. However, an MNF division may be neither MM nor EFX, which is a weaker form of EF. We conjecture that there is always an EFX allocation that satisfies MM, ensuring that an allocation is maximin, precisely the property that Rawls (1971/1999) championed. We discuss four broader philosophical implications of our more technical analysis.

This paper examines whether certain workers have a moral claim to decent wages for work that contributes to the social surplus in a fundamental way. This "fundamental" way refers to work whose fruits other members of society need to live acceptably good lives (not maximally good ones). The paper argues that what is due to this type of worker is based on the nature of the benefit that her labor produces for others in society and on the returned value that such labor should, by virtue of fair play considerations, command. The core of the argument in the paper is that such benefit is connected to an important dimension of human freedom, which is enabled by the absence of necessity to toil to secure subsistence in society. The paper also dwells on questions related to whose responsibility it should be to guarantee decent pay for contributions to society.

What explains why we are subjects for whom objects can have value, and what explains which objects have value for us? Axiologicians say that the value of humanity is the answer. I argue that our value, no matter what it is like, cannot perform this task. We are animals among others. An explanation of the value of objects for us must fit into an explanation of the value of objects for animals generally. Different objects have value for different animals. Those differences depend on differences in animal natures and, in particular, on the diverse characteristic capacities of different animals. Once we invoke animal natures, there is nothing for the value of animality, including the value of humanity, to explain.

In his article "Against Schmought" (The Journal of Philosophy, CXVIII 2021), Matthew Vermaire discusses the central problems I focus on in my book Choosing Normative Concepts (2017). Vermaire defends an attempted solution, or dissolution, of these problems. While there is much in Vermaire’s discussion to admire, I do not think Vermaire’s solution works, and here I explain why. Key to my response is the distinction between employing a concept and reasoning about the concept.

We can have credences in an infinite number of propositions—that is, our opinion set can be infinite. Accuracy-first epistemologists have devoted themselves to evaluating credal states with the help of the concept of ‘accuracy’. Unfortunately, under several innocuous assumptions, infinite opinion sets yield several undesirable results, some of which are even fatal, to accuracy-first epistemology. Moreover, accuracy-first epistemologists cannot circumvent these difficulties in any standard way. In this regard, we will suggest a non-standard approach, called a relativistic approach, to accuracy-first epistemology and show that such an approach can successfully circumvent undesirable results while having some advantages over the standard approach.

This paper motivates and defends alethic nihilism, the theory that nothing is true. I first argue that alethic paradoxes like the Liar and Curry motivate nihilism; I then defend the view from objections. The critical discussion has two primary outcomes. First, a proof of concept. Alethic nihilism strikes many as silly or obviously false, even incoherent. I argue that it is in fact well-motivated and internally coherent. Second, I argue that deflationists about truth ought to be nihilists. Deflationists maintain that the utility of the truth predicate is exhausted by its expressive role, and I argue that the truth predicate can still play this expressive role even if nothing is true. As such, deflationists do not stand to lose anything by accepting nihilism. Since they also stand to gain an elegant solution to the alethic paradoxes, on balance deflationists ought to be nihilists.

Recent debates about supererogatory rescues have sought to explain how it can be wrong to perform a suboptimal rescue although it would be permissible not to rescue at all. This paper proposes a new solution to this puzzle. It argues that existing accounts have neglected two critical considerations. First, contrary to what is commonly assumed, a rescue’s supererogatory nature has no bearing on the duties that apply to agents who rescue in supererogatory fashion. Second, we cannot justify harms caused as a side effect of supererogatory rescues by appealing to the fact that it would have been permissible not to rescue at all. Ultimately, the paper proposes, the same duties that apply in cases in which rescuing is required also apply in cases in which rescuing is supererogatory. A rescue’s supererogatory nature, it turns out, is not the game changer we thought it was.

McTaggart’s argument for the unreality of time was first published in the 1908 article “The Unreality of Time,” and a revised version appeared in the 1927 book The Nature of Existence. I argue that these two versions are significantly different. The second construction of the argument is important because it neutralizes a compelling objection. McTaggart’s initial argument tries to show that the conception of an A-series is self-contradictory. A natural objection is that the apparent contradiction can be resolved by making clear that an event has incompatible A-properties only successively. McTaggart anticipates and responds to the objection. My main contention is this: McTaggart’s initial response to the objection fails, but in the second construction of his argument he succeeds in showing that the contradiction cannot be resolved in the way suggested by the objection. I also explain why the second construction has been overlooked for so long.

This paper asks: Is the quantifier variantist committed to metaphysical vagueness? My investigation of this question goes via a study of vague existence. I’ll argue that the quantifier variantist is committed to vague existence and that the vague existence posited by the variantist requires a puzzling sort of metaphysical vagueness. Specifically, I distinguish between (what I call) positive and negative metaphysical vagueness. Positive metaphysical vagueness is (roughly) the claim that there is vagueness in the world; negative metaphysical vagueness is (roughly) the claim that there is vagueness that is not in our language or thought. I’ll argue that the quantifier variantist’s commitment to vague existence comes with positive metaphysical vagueness—even if it doesn't require negative metaphysical vagueness.

This paper offers a defense of a much-maligned Leibnizian argument for the Principle of Sufficient Reason, the principle according to which whatever is has a sufficient reason or explanation. While Leibniz’s argument is widely thought to rely on a question-begging premise, the paper offers a wholly original and non-question-begging defense of that premise, a defense that Leibniz did not anticipate. The paper does not present this defense of Leibniz's argument as an interpretation of Leibniz; rather, the paper—more modestly in one way, less modestly in another—simply claims that this argument succeeds.

There is a type of metaphysical picture that surfaces in a range of philosophical discussions, is of intrinsic interest, and yet remains ill-understood. According to this picture, the world contains a range of standpoints relative to which different facts obtain. Any true representation of the world cannot but adopt a particular standpoint. The aim of this paper is to propose a regimentation of a metaphysics that underwrites this picture. Key components are a factive notion of metaphysical relativity, a deflationary notion of adopting standpoints, and two kinds of valid inference, one that allows one to abandon standpoints and one that does not. To better understand how theories formulated in terms of this framework are situated in dialectical space, I sketch a theory in the philosophy of time that admits both temporal and atemporal standpoints.
