We argue that Lewis would have rejected recent appeals to the notions of ‘metaphysical dependency’, ‘grounding’ and ‘ontological priority’, because he would have held that they’re not needed and they’re not intelligible. We argue our case by drawing upon Lewis’s views on supervenience, the metaphysics of singletons and the dubiousness of Kripke’s essentialism.

In ordinary language, in the medical sciences, and in the overlap between them, we frequently make claims which imply that we might have had different gametic origins from the ones we actually have. Such statements seem intuitively true and coherent. But they counterfactually ascribe different DNA to their referents and therefore contradict material-origin essentialism, which Kripke and his followers argue is intuitively obvious. In this paper I argue, using examples from ordinary language and from philosophy of medicine and bioethics, that (...) statements which attribute alternative material origins to their referents are useful, common in political and medical reasoning, and in many cases best interpreted literally. So we must replace the doctrine of material-origin essentialism with one that can make sense of ordinary discourse and the language of the medical sciences. I propose an anti-essentialist account of such counterfactuals according to which individuals’ modal properties are relative to a given inquiry. (shrink)

Nous comparons les notions d’usage et de signification chez Ludwig Wittgenstein et Martin Heidegger. Contrairement à Jocelyn Benoist, nous pensons que l’analogie entre Wittgenstein et Heidegger n’est pas superficielle. La métaphysique de Heidegger explicite certaines présuppositions implicites de la seconde philosophie de Wittgenstein. Le pragmatisme naturaliste de Wittgenstein peut être théorisé. Notamment la notion wittgensteinienne d’usage, ou de jeu de langage, peut être comprise comme une pratique à la fois naturelle et normative régie par des règles. -/- Wittgenstein’s notions of (...) use and meaning are compared with the corresponding Heidegger’s ones. Unlike Jocelyn Benoist, we suggest that the analogy between Wittgenstein and Heidegger is not superficial. Heidegger’s metaphysics makes explicit some of the implicit presuppositions of Wittgenstein’s philosophy. Wittgenstein’s naturalistic pragmatism can be theorized. In particular, Wittgenstein’s notion of use, or language game, can be understood as both natural and normative rule- governing practice. (shrink)

The distinction between the body schema and the body image has become the stock in trade of much recent work in cognitive neuroscience and philosophy. Yet little is known about the interactions between these two types of body representations. We need to account not only for their dissociations in rare cases, but also for their convergence most of the time. Indeed in our everyday life the body we perceive does not conflict with the body we act with. Are the body (...) image and the body schema then somehow reshaping each other or are they relatively independent and do they only happen to be congruent? On the basis of the study of bodily hallucinations, we consider which model can best account for the body schema/body image interactions. (shrink)

Physicalistic theories of psychology are a classic case of scientific imperialism: the explanatory capacity of physics, both with respect to its methods and to its domain, is taken to extend beyond the traditional realm of physics, and into that of psychology. I argue in this paper that this particular imperialistic venture has failed. Contemporary psychology uses methods not modelled on those of physics, embracing first-personal methodology where physics is strictly impersonal. I make the case that whether or not scientific imperialism (...) is in general harmful, in this instance naturalists who reject first philosophy should give up physicalist imperialism. Using only general principles from the philosophy of logic plus accepted physicalist criteria of identity, I show that first-personal psychology embodies a minor but fruitful increase in expressive strength compared to impersonal psychology: the ability to distinguish descriptively indiscriminable posits.

Brief note explaining the content, importance, and historical context of my joint translation of Quine's The Significance of the New Logic with my single-authored historical-philosophical essay 'Willard Van Orman Quine's Philosophical Development in the 1930s and 1940s'.

An odd dissensus between confident metaphysicians and neopragmatist antimetaphysicians pervades early twenty-first century analytic philosophy. Each faction is convinced their side has won the day, but both are mistaken about the philosophical legacy of the twentieth century. More historical awareness is needed to overcome the current dissensus. Lewis and his possible-world system are lionised by metaphysicians; Quine’s pragmatist scruples about heavy-duty metaphysics inspire antimetaphysicians. But Lewis developed his system under the influence of his teacher Quine, inheriting from him his empiricism, (...) his physicalism, his metaontology, and, I will show in this paper, also his Humeanism. Using published as well as never-before-seen unpublished sources, I will make apparent that both heavy-duty metaphysicians and neopragmatist antimetaphysicians are wrong about the roles Quine and Lewis played in the development of twentieth-century philosophy. The two are much more alike than is commonly supposed, and Quine much more instrumental to the pedigree of current metaphysics. (shrink)

Susan Stebbing’s work on incomplete symbols and analysis was instrumental in clarifying, sharpening, and improving the project of logical constructions which was pivotal to early analytic philosophy. She dispelled use-mention confusions by restricting the term ‘incomplete symbol’ to expressions eliminable through analysis, rather than those expressions’ purported referents, and distinguished linguistic analysis from analysis of facts. In this paper I explore Stebbing’s role in analytic philosophy’s development from anti-holism, presupposing that analysis terminates in simples, to the more holist or foundherentist (...) analytic philosophy of the later 20th century. I read Stebbing as a transitional figure who made room for more holist analytic movements, e.g., applications of incomplete symbol theory to Quinean ontological commitment. Stebbing, I argue, is part of a historical narrative which starts with the holism of Bradley, an early influence on her, to which Moore and Russell’s logical analysis was a response. They countered Bradley’s holist reservations about facts with the view that the world is built up out of individually knowable simples. Stebbing, a more subtle and sympathetic reader of the British idealists, defends analysis, but with important refinements and caveats which prepared the way for a return to foundherentism and holism within analytic philosophy.

Touch seems to enjoy some epistemic advantage over the other senses when it comes to attest to the reality of external objects. The question is not whether only what appears in tactile experiences is real. It is that only whether appears in tactile experiences feels real to the subject. In this chapter we first clarify how exactly the rather vague idea of an epistemic advantage of touch over the other senses should be interpreted. We then defend a “muscular thesis”, to (...) the effect that only the experience of resistance to our motor efforts, as it arises in effortful touch, presents us with the independent existence of some causally empowered object. We finally consider whether this muscular thesis applies to the perception of our own body. (shrink)

In 1901 Russell had envisaged the new analytic philosophy as uniquely systematic, borrowing the methods of science and mathematics. A century later, have Russell’s hopes become reality? David Lewis is often celebrated as a great systematic metaphysician, his influence proof that we live in a heyday of systematic philosophy. But, we argue, this common belief is misguided: Lewis was not a systematic philosopher, and he didn’t want to be. Although some aspects of his philosophy are systematic, mainly his pluriverse of (...) possible worlds and its many applications, that systematicity was due to the influence of his teacher Quine, who really was an heir to Russell. Drawing upon Lewis’s posthumous papers and his correspondence as well as the published record, we show that Lewis’s non- Quinean influences, including G.E. Moore and D.M. Armstrong, led Lewis to an anti- systematic methodology which leaves each philosopher’s views and starting points to his or her own personal conscience. (shrink)

Elisabeth was the first of Descartes' interlocutors to press concerns about mind-body union and interaction, and the only one to receive a detailed reply, unsatisfactory though she found it. Descartes took her tentative proposal `to concede matter and extension to the soul' for a confused version of his own view: `that is nothing but to conceive it united to the body. Contemporary commentators take Elisabeth for a materialist or at least a critic of dualism. I read her instead as a (...) dualist of a different variety from Descartes: a forerunner of twenty-first century naturalistic dualism which calls for empirical investigation of the psychological and its posits to be taken just as seriously as physics and its posits. -/- I argue that Elisabeth, a keen scholar of mechanistic physics, objected not to substance dualism per se but to the residual Scholasticism of Descartes' account of mind-body causality and his dogmatism about principal attributes. She queried Descartes' categorisation of the `action' of thought as mind's principal attribute, and his identification of it with the merely negative property of immateriality, holding instead that further philosophical and empirical investigation into the nature of the mind is necessary. I problematise the materialist interpretation of Elisabeth with reference to later letters where she dismissed the materialist Objections of Hobbes and Gassendi and continued to urge further clarifications to Cartesian dualism. I explore Elisabeth's contrasting of statements of mechanistic physics with statements about thought, and her call for further investigation into the properties of the mind, and argue they mark her out as a forerunner of contemporary naturalistic dualism which proposes substance dualism as a best interpretation of recent psychology and of the difference in logical form between current physics and current psychology.

Quine's views on ontology and naturalism are well-known but rarely considered in tandem. According to my interpretation the connection between them is vital. I read Quine as a global epistemic structuralist. Quine thought we only ever know objects qua solutions to puzzles about significant intersections in observations. Objects are always accessed descriptively, via their roles in our best theory. Quine's Kant lectures contain an early version of epistemic structuralism with uncharacteristic remarks about the mental. Here Quine embraces mitigated anomalous monism, (...) allowing introspection and the availability in principle of full physical descriptions of the perceptual states which get science off the ground. Later versions abandon these ideas. My epistemic-structural interpretation explains why. I argue first-personal introspective access to mental states is incompatible with global epistemic structuralism. (shrink)

As analytic philosophy is becoming increasingly aware of and interested in its own history, the study of that field is broadening to include, not just its earliest beginnings, but also the mid-twentieth century. One of the towering figures of this epoch is W.V. Quine (1908-2000), champion of naturalism in philosophy of science, pioneer of mathematical logic, trying to unite an austerely physicalist theory of the world with the truths of mathematics, psychology, and linguistics. Quine's posthumous papers, notes, and drafts revealing (...) the development of his views in the forties have recently begun to be published, as well as careful philosophical studies of, for instance, the evolution of his key doctrine that mathematical and logical truth are continuous with, not divorced from, the truths of natural science. But one central text has remained unexplored: Quine's Portuguese-language book on logic, his 'farewell for now' to the discipline as he embarked on an assignment in the Navy in WWII. Anglophone philosophers have neglected this book because they could not read it. Jointly with colleagues, I have completed the first full English translation of this book. In this accompanying paper I draw out the main philosophical contributions Quine made in the book, placing them in their historical context and relating them to Quine's overall philosophical development during the period. Besides significant developments in the evolution of Quine's views on meaning and analyticity, I argue, this book is also driven by Quine's indebtedness to Russell and Whitehead, Tarski, and Frege, and contains crucial developments in his thinking on philosophy of logic and ontology. This includes early versions of some arguments from 'On What There Is', four-dimensionalism, and virtual set theory. (shrink)

Editors' introduction which discusses Quine's place in the history of analytic philosophy and the content of the papers collected in this volume.

I respond to the commentaries on 'Grace de Laguna's Analytic and Speculative Philosophy' offered by Peter Olen [2023], Trevor Pearce, Anthony Fisher, Marguerite La Caze and Frederique Janssen-Lauret. In doing so, I bring out some of the value of de Laguna’s perspectivism and of her treatment of modality. I also further clarify how she departs from pragmatism and from analytic philosophy, and how she relates to continental philosophy.

In February 2021, the French Minister of Higher Education and Research, Frédérique Vidal, ordered an inquiry – to be led by the French National Centre for Scientific Research – about the alleged “Islamo-leftism” which, according to her, was corrupting French academia. Vidal's concern was, purportedly, to distinguish “what falls under academic research and what falls under militancy and opinion”. She had in mind, in particular, recent interdisciplinary fields in the social sciences, such as Postcolonial Studies. Her statements caused a (...) controversy in French academia as well as outside. The goal of this paper is to present this controversy and analyse it in light of the philosophical literature on autonomy of, and values in, science. After recalling the political and institutional context of the controversy, I present Vidal’s intervention and various reactions to it, which can roughly be classified pro and contra Vidal's statements. I then provide a philosophical discussion of the controversy, by recalling the philosophical debate to which it is related, and analysing the assumptions, arguments and actions of both camps. I show in particular that a political intervention inside the very production of academic knowledge implies a strong risk of censorship, and that letting academia self-regulate itself with respect to the validation of knowledge remains the best way to go. I conclude with the deeper questions raised by this controversy: the social role of universities, and the institutional aspects of scientific knowledge validation. (shrink)
