This axiomatization parallels the structure of first order logic exactly. It can be read as a reduction of the axiom scheme of comprehension of TST(U) to finitely many axiom templates (up to type assignment) or as a reduction of the axiom scheme of stratified comprehension to finitely many axioms. Probably one should assume weak extensionality: nonempty sets with the same elements are equal.

Motion—and, in particular, local motion or change in location—plays a central role in Kenelm Digby’s natural philosophy and in his arguments for the immateriality of the soul. Despite this, Digby’s account of what motion consists in has yet to receive much scholarly attention. In this paper, I advance a novel interpretation of Digby on motion. According to it, Digby holds that for a body to move is for it to divide from and unify with other bodies. This is a view of motion—as change in relations of parthood—that Alison Peterman attributes to Digby’s contemporary and acquaintance, Margaret Cavendish. Having shown that Digby’s presentation of the view predates Cavendish’s by more than a decade, I make a case that Digby’s work influenced Cavendish’s on this topic. In developing and defending my reading, I consider to what extent the Digbean account of motion and the arguments for it accord with the ideals of the mechanical philosophy emerging in the early modern period.

When a person decides to do something in the future, she forms an intention and her intention persists. Philosophers have thought about the rational requirement that an agent’s intention persists until its execution. But philosophers have neglected to think about the causal memory mechanisms that could enable this kind of persistence and its role in rational long-term agency. Our aim of this paper is to fill this gap by arguing that memory for intention is a specific kind of memory. We do this by evaluating and rejecting standard declarative accounts of memory for intention and arguing for the plausibility of an alternative model of memory for intention. We argue for the alternative by spelling out a number of computational principles that could enable retaining and retrieving intentions from long-term memory. These principles could explain a number of core features of intentions.

Fictionalists about a kind of disputed entity aim to give a face-value interpretation of our discourse about those entities without affirming their existence. The fictionalist’s commitment to non-realism leaves open three options regarding their ontological position: they may deny the existence of the disputed entities (anti-realism), remain agnostic regarding their existence (agnosticism), or deny that there are ontological facts of the matter (ontological anti-realism). This paper outlines a method of adjudicating between these options and argues that fictionalists may be expected to hold preferences between them. The typical arguments and motivations for fictionalism lead naturally to a practice-based metaontological framework under which our practices regarding a kind of disputed entity might inform our ontological beliefs about those entities. When that framework is applied to fictionalism, it is found that the usual motivations for fictionalism lead naturally, though not decisively, to ontological anti-realism. And, where there are reasons against ontological anti-realism, fictionalism leans more toward anti-realism than agnosticism.

Feminists have disagreed about whether women can choose gendered subordination autonomously. Less attention has been paid, however, to the socio-ontological questions that underlie this debate. This article introduces novel cases of ‘thwarted autonomy,’ in which women pursue autonomy but in ways that reinforce gendered subordination, in order to challenge dominant proceduralist and substantivist views, as well as motivate an expressivist view of the social self as a promising foundation for an account of autonomy. On this view, which draws on the Hegelian tradition, agents must embody their desires and values in the social world to achieve self-understanding. Social meanings and norms therefore mediate the form an agent’s expressive activity takes, and the sense of self she develops. An expressivist view, I argue, allows us to reinterpret women’s outward acquiescence to gendered subordination as an attempt to express autonomy in an oppressive social context. It also points towards a robustly social conception of autonomy to aid in the diagnosis and redress of patriarchal oppression.

According to reductivist axiological perfectionism about well-being (RAP), well-being is constituted by the development and exercise of central human capacities. In defending this view, proponents have relied heavily on the claim that RAP provides a unifying explanation of the entries on the ‘objective list’ of well-being constituents. I argue that this argument fails to provide independent support for the theory. RAP does not render a plausible objective list unless such a list is used at every stage of theory development to shape the details of the view. Absent such motivated fine-tuning, RAP even fails to provide a satisfying account of two supposed paradigm cases of perfectionist value: achievement and knowledge. Thus, if RAP is to be defended, it must be defended directly by providing reasons for accepting the axiological principle at its heart. It cannot be defended, indirectly, by pointing to its attractive implications.

A specter is haunting economics—the specter of revealed preference theory. Many philosophers of old have entered into an alliance to exorcise this specter; Sen (1977) and Hausman (2012), Dietrich and List (2016), and Guala (2012; 2019). In the face of the trenchant critique it has faced, the longevity of revealed preference theory is quite surprising. While it still holds considerable power among economists, in recent years also philosophers have begun to offer novel arguments in its defense (e.g., Vredenburgh 2020; Clarke 2020; Thoma 2021a; 2021b). At its core, revealed preference theory can be stated as the view that preferences are just patterns in choice-behavior. My aim in this paper is to argue against the revival of revealed preference theory. Towards this end, I will first outline the different facets of revealed preference theory (Section 2). I will then briefly present the two most common arguments that philosophers of economics have offered against it. In particular, I will look at the argument from belief and the argument from causality (Section 3).

Is the overall value of a world just the sum of values contributed by each value-bearing entity in that world? Additively separable axiologies (like total utilitarianism, prioritarianism, and critical level views) say ‘yes’, but non-additive axiologies (like average utilitarianism, rank-discounted utilitarianism, and variable value views) say ‘no’. This distinction appears to be practically important: among other things, additive axiologies generally assign great importance to large changes in population size, and therefore tend to strongly prioritize the long-term survival of humanity over the interests of the present generation. Non-additive axiologies, on the other hand, need not assign great importance to large changes in population size. We show, however, that when there is a large enough ‘background population’ unaffected by our choices, a wide range of non-additive axiologies converge in their implications with additive axiologies—for instance, average utilitarianism converges with critical-level utilitarianism and various egalitarian theories converge with prioritarianism. We further argue that real-world background populations may be large enough to make these limit results practically significant. This means that arguments from the scale of potential future populations for the astronomical importance of avoiding existential catastrophe, and other arguments in practical ethics that seem to presuppose additive separability, may succeed in practice whether or not we accept additive separability as a basic axiological principle.

It is widely accepted that public discourse as we know it is less than ideal from an epistemological point of view. In this paper, we develop an underappreciated aspect of the trouble with public discourse: what we call the Listening Problem. The listening problem is the problem that public discourse has in giving appropriate uptake and reception to ideas and concepts from oppressed groups. Drawing on the work of Jürgen Habermas and Nancy Fraser, we develop an institutional response to the listening problem: the establishment of what we call Receptive Publics, discursive spaces designed to improve listening skills and to give space for counterhegemonic ideas.

This paper considers two conceptual expansions of Du Boisian double consciousness—white double consciousness (Alcoff 2015) and kaleidoscopic consciousness (Medina 2013)—both of which aim to articulate the moral-epistemic potential of cultivating double consciousness from racially dominant or other socially privileged positions. We analyze these concepts and challenge them on the grounds that they lack continuity with their Du Boisian predecessor and face problems of practical feasibility. As we show, these expansions obscure structural barriers that make white double consciousness and kaleidoscopic consciousness unlikely antidotes to the kind of racial domination that double consciousness was introduced to illuminate. We conclude that while more intersectional and pluralistic accounts of double consciousness may be desirable, the project of expansion has moral limits. Identifying these limitations, we outline ways in which double consciousness—as a tool for conceptualizing the genealogy of structural anti-Blackness—remains valuable in the absence of ever-expanding revision.

A classic and fraught question in the philosophy of film is this: when you watch a film, do you experience yourself in the world of the film, observing the scenes? In this paper, we argue that this subject of film experience is sometimes a mere impersonal viewpoint, sometimes a first-personal but unindexed subject, and sometimes a particular, indexed subject such as the viewer herself or a character in the film. We first argue for subject pluralism: there is no single answer to the question of what kind of subjectivity, if any, is mandated across film sequences. Then, we defend unindexed subjectivity: at least sometimes, films mandate an experience that is first-personal but not tied to any particular person, not even to the viewer. Taken together, these two theses allow us to see film experience as more varied than previously appreciated and to bridge in a novel way the cognition of film with the exercise of other imaginative capacities, such as mindreading and episodic recollecting.

The main goal of this essay is to propose and make plausible a framework for developing a philosophical account of musical notation. The proposed framework countenances four elements of notation: symbols (abstract objects that collectively constitute the backbone of a ‘system’ of notation), their characteristic ‘forms’ (for example, shapes, understood abstractly), the concrete instances, or ‘engravings’, of those forms, and the meanings of the symbols. It is argued that these elements are distinct. Along the way, several preliminary arguments are given for how one ought to understand them—for example, it is suggested that engravings represent symbols rather than instantiate forms, although they are characteristically seen to represent a symbol by being seen to instantiate an associated form. Having proposed this framework, the essay explores the nature of musical instructions, as the meanings of symbols, and offers an argument in favor of the commonly held (but recently challenged) view that those meanings are imperative. Specifically, composites of musical notation (paradigmatically, musical scores) primarily express instructional meaning, and denote something like ‘sonic structures’ only secondarily, in virtue of their primary, imperative, meaning.

I want to comment on an old objection to the “similarity analysis” of counterfactuals, and on a more recent, but related, argument for counterfactual skepticism. According to the similarity analysis, a counterfactual ? > ? is true iff ? is true at all ? worlds that are most similar, in certain respects, to the actual world. The old objection that I have in mind is that the similarity analysis fails to validate Simplification of Disjunctive Antecedents (SDA), the inference from (? ∨ ?) > ? to ? > ? and ? > ?. Imagine someone utters (1a) on a hot summer day.

Jc Beall’s Divine Contradiction is a fascinating defence of the idea that contradictions are true of the tri-personal God. This project requires a logic that avoids the consequence that every proposition follows from a contradiction. Beall presents such a logic. This ‘gap/glut’ logic is the topic of this article. A gap/glut logic presupposes that falsity is not simply the absence of truth – for a proposition that is true may also be false. This article is essentially an examination of the idea that falsity is not simply untruth. The author rejects this position but does not claim to have an argument against it. In lieu of an argument, he presents three ‘considerations’. First, it is possible to give an intuitive semantics for the language of sentential logic that yields ‘classical’ sentential logic (including ‘p, ¬ p ⊢ q’) and which makes no mention of truth-values. Second, it is possible to imagine a race who manage their affairs very well without having the concept ‘falsity’. Third, it is possible to construct a semantics that yields a logic identical with the dialetheist logic and which makes no mention of truth-values – and which, far from being plausible, seems pointless.

This analysis shows Cantor's diagonal definition in his 1891 paper was not compatible with his horizontal enumeration of the infinite set M. The diagonal sequence was a counterfeit which he used to produce an apparent exclusion of a single sequence to prove the cardinality of M is greater than the cardinality of the set of integers N.

What is the proper role for scientists in policymaking? This paper explores various roles that scientists can play, with an eye to questions that these roles raise about value-neutrality and technocracy. Where much philosophical literature is concerned with the conduct of research or the transmission of research results to policymakers, I am interested in various non-research roles that scientists take on in policymaking. These include raising the alarm on issues, framing and conceptualising problems, formulating potential policies, assessing policy options for expected efficacy, and more. I consider examples from climate change and Covid- 19 policymaking. My intention is to encourage philosophers to expand their interest in values in science out from the conduct of research to the wide array of roles that scientists play in policymaking. The paper is therefore an overview of the landscape of potential research questions, rather than a presentation of a single argument.

Realism about quantum theory naturally leads to realism about the quantum state of the universe. It leaves open whether it is a pure state represented by a wave function, or an impure one represented by a density matrix. I characterize and elaborate on Density Matrix Realism, the thesis that the universal quantum state is objective but can be impure. To clarify the thesis, I compare it with Wave Function Realism, explain the conditions under which they are empirically equivalent, consider two generalizations of Density Matrix Realism, and answer some frequently asked questions. I end by highlighting an implication for scientific realism.

Alonzo Church proposed a theory of sequences of functions and their arguments as surrogates for Russellian singular propositions and singular concepts. Church’s proposed theory accords with his Alternative (0), the strictest of his three competing criteria for strict synonymy. The currently popular objection to strict criteria like (0) on the basis of the Russell-Myhill antinomy is rebutted. Russell-Myhill is not a problem specifically for 1 ACKOWLEDGMENTS: This essay is dedicated to the memory of the great philosopher and logician, Alonzo Church. I had the good fortune to study under Prof. Church (among others) through the 1970s. Years later he read my Frege’s Puzzle (1986), in which I defend what is now called a Millian theory of semantic content. In May 1989, Prof. Church sent me a pair of manuscripts, then not yet published, in which he independently proposed similar ways of developing a theory of n–tuple surrogates for singular propositions. Church’s cover letter began “Just to prove that great minds run in the same channel.” Although his throwaway remark did not reflect a genuine assessment—of me or of himself—it was exceedingly generous, and the memory of it can still cause me to blush. The present essay is in part a much delayed result of careful study of Church’s excellent papers. I am profoundly in his debt.

I propose an approach to liar and Curry paradoxes inspired by the work of Roger Swyneshed in his treatise on insolubles (1330-1335). The keystone of the account is the idea that liar sentences and their ilk are false (and only false) and that the so-called “capture” direction of the T-schema should be restricted. The proposed account retains what I take to be the attractive features of Swyneshed’s approach without leading to some worrying consequences Swyneshed accepts. The approach and the resulting logic (called “Swynish Logic”) are non-classical, but are consistent and compatible with many elements of the classical picture including modus ponens, modus tollens, and double-negation elimination and introduction. It is also compatible with bivalence and contravalence. My approach to these paradoxes is also immune to an important kind of revenge challenge that plagues some of its rivals.

I think it’s wrong for us to kill innocent people. Some fellow deontologists, however, think this prohibition should be restricted to say that it’s wrong for us to kill nonconsenting innocent people.

Leddington (2016) remains the leading contemporary philosophical account of magic, one that has been relatively unchallenged. In this discussion piece, I have three aims; namely, to (i) criticise Leddington’s attempt to explain the experience of magic in terms of belief-discordant alief; (ii) explore the possibility that much, if not all, of the experience of magic can be explained by mundane belief-discordant perception; and (iii) argue that make-believe is crucial to successful performances of magic in ways Leddington at best overlooks and at worst denies.

Throughout the history of automated reasoning, mathematics has been viewed as a prototypical domain of application. It is therefore surprising that the technology has had almost no impact on mathematics to date and plays almost no role in the subject today. This article presents an optimistic view that the situation is about to change. It describes some recent developments in the Lean programming language and proof assistant that support this optimism, and it reflects on the role that automated reasoning can and should play in mathematics in the years to come.

Empirical research provides striking examples of non-human animal responses to death, which look very much like manifestations of grief. However, recent philosophical work appears to challenge the idea that animals can grieve. Grief, in contrast to more rudimentary emotional experiences, has been taken to require potentially human-exclusive abilities like a fine-grained sense of particularity, an ability to project toward the distal future and the past, and an understanding of death or loss. This paper argues that these features do not rule out animal grief and are present in many animal loss responses. It argues that the principal kind of “understanding” involved in grief is not intellectual but is instead of a practical variety available to animals, and outlines ways that the disruption to an animal’s life following a loss can hinge upon a specific individual and involve a degree of temporal organisation.
