Bertrand Russell, in the second of his 1914 Lowell lectures, Our Knowledge of the External World, asserted famously that ‘every philosophical problem, when it is subjected to the necessary analysis and purification, is found either to be not really philosophical at all, or else to be, in the sense in which we are using the word, logical’ (Russell 1993, p. 42). He went on to characterize that portion of logic that concerned the study of forms of propositions, or, as he (...) called them, ‘logical forms’. This portion of logic he called ‘philosophical logic’. Russell asserted that ... some kind of knowledge of logical forms, though with most people it is not explicit, is involved in all understanding of discourse. It is the business of philosophical logic to extract this knowledge from its concrete integuments, and to render it explicit and pure. (p. 53) Perhaps no one still endorses quite this grand a view of the role of logic and the investigation of logical form in philosophy. But talk of logical form retains a central role in analytic philosophy. Given its widespread use in philosophy and linguistics, it is rather surprising that the concept of logical form has not received more attention by philosophers than it has. The concern of this paper is to say something about what talk of logical form comes to, in a tradition that stretches back to (and arguably beyond) Russell’s use of that expression. This will not be exactly Russell’s conception. For we do not endorse Russell’s view that propositions are the bearers of logical form, or that appeal to propositions adds anything to our understanding of what talk of logical form comes to. But we will be concerned to provide an account responsive to the interests expressed by Russell in the above quotations, though one clarified of extraneous elements, and expressed precisely. For this purpose, it is important to note that the concern expressed by Russell in the above passages, as the surrounding text makes clear, is a concern not just with logic conceived narrowly as the study of logical terms, but with propositional form more generally, which includes, e.g., such features as those that correspond to the number of argument places in a propositional function, and the categories of objects which propositional....

This chapter reviews the major contributions of Donald Davidson to philosophy in the 20th century.

In this chapter, we defend the view that Davidson aimed not to replace the theory of meaning with the theory of truth, or to capture only certain features of the ordinary notion of meaning for certain theoretical purposes, but rather to pursue the traditional project of explaining in the broadest terms “what it is for words to mean what they do” through a clever bit of indirection, namely, by exploiting the recursive structure of a Tarskian‐style truth theory, which meets certain (...) constraints in an illuminating way, to generate theorems that give truth conditions for object language sentences that at the same time provide interpretations of them.

Under what conditions are two utterances utterances of the same word? What are words? That these questions have not received much attention is rather surprising: after all, philosophers and linguists frequently appeal to considerations about word and sentence identity in connection with a variety of puzzles and problems that are foundational to the very subject matter of philosophy of language and linguistics.1 Kaplan’s attention to words is thus to be applauded. And there is no doubt that his discussion contains many (...) useful insights. Nevertheless, we find his picture deeply flawed for a variety of crosscutting reasons. Our aim in this paper is to further advance an understanding of the nature of words, both by remedying the problems with Kaplan’s account, and also by achieving a suitable perspective on what the metaphysical investigation of word identity can hope to achieve. Our discussion divides into four parts. In Part One, we examine and critique Kaplan’s discussion of a contrast integral to his own account: that between the type-token and the stage-continuant conceptions of words. In Part Two, we present three constraints on any account of words and two further themes in Kaplan’s discussion central to his conception of words – the role of repetition and the constitutive authority of intentions. While these ideas have laudable motivations, we argue they are far from the best way of making good on the insights that drive them. The final two sections take a skeptical turn. In Part Three, we express doubt about Kaplan’s presumption of the importance of what he calls ‘common currency names’, thus raising a suspicion that he may be in pursuit of chimera. Finally, in Part Four, we express pessimism about whether interesting answers to question above will be forthcoming, and suggest that the legitimacy of our word ontology need not depend on the availability of such answers. Along the way, we tease apart a number of metaphysical questions in the vicinity of the topic of word individuation – questions that are often not disentangled – and consider how the discussion of the previous parts bears on them..

This paper responds to a critical review of our 2005 book Donald Davidson: Meaning, Truth, Language and Reality, by Frederick Stoutland. It identifies a number of serious misreadings of both Davidson and the book.

Complex demonstratives, expressions of the form 'That F', 'These Fs', etc., have traditionally been taken to be referring terms. Yet they exhibit many of the features of quantified noun phrases. This has led some philosophers to suggest that demonstrative determiners are a special kind of quantifier, which can be paraphrased using a context sensitive definite description. Both these views contain elements of the truth, though each is mistaken. We advance a novel account of the semantic form of complex demonstratives that (...) shows how to reconcile the view that they function like quantified noun phrases with the view that simple demonstratives function as context sensitive referring terms wherever they occur. If we are right, previous accounts of complex demonstratives have misconceived their semantic role; and philosophers relying on the majority view in employing complex demonstratives in analysis have proceeded on a false assumption.

This chapter reviews interpretations of Davidson's project in the theory of meaning and argues against a variety of views according to which Davidson intended to reduce meaning to some variety of truth conditions or replace the project of giving a theory of meaning with a theory of truth, and in support of interpreting him as offering an indirect way of achieving the goals of the traditional project by appeal to knowledge of facts about a semantic theory of truth for the (...) language, including that it was confirmable from the standpoint of the radical interpreter.

This chapter reviews the work and influence of Donald Davidson across all the areas to which he contributed.

This paper articulates and defends a conception of logical form as semantic form revealed by a compositional meaning theory. On this conception, the logical form of a sentence is determined by the semantic types of its primitive terms and their mode of combination as it relates to determining under what conditions it is true. We develop this idea in the framework of truth-theoretic semantics. We argue that the semantic form of a declarative sentence in a language L is revealed by (...) a (canonical) proof of its T- sentence in an interpretive truth theory for L. We give a precise characterization of sameness of logical form between any two declarative sentences in any two languages in terms of the notion of corresponding proofs in interpretive truth theories for the languages. We illustrate the utility of this approach with a number of examples. We then extend the characterization to non-declaratives in a generalization of truth-theoretic semantics that appeals to fulfillment conditions, of which truth conditions are one variety. On this approach, logical forms are not reified, and the notion of sameness of logical form is treated as conceptually basic. We discuss the relation of this conception of logical form to the project of identifying logical constants, reviewing two approaches, one of which takes topic neutrality as central, the other recursion. We argue that the project of identifying logical constants for the purposes of classifying together valid arguments is largely independent of that identifying logical form of sentences, and urge an ecumenical approach to extending talk of logical constants beyond where it is currently well-grounded.

Traditionally, pronouns are treated as ambiguous between bound and demonstrative uses. Bound uses are non-referential and function as bound variables, and demonstrative uses are referential and take as a semantic value their referent, an object picked out jointly by linguistic meaning and a further cue—an accompanying demonstration, an appropriate and adequately transparent speaker’s intention, or both. In this paper, we challenge tradition and argue that both demonstrative and bound pronouns are dependent on, and co-vary with, antecedent expressions. Moreover, the semantic (...) value of a pronoun is never determined, even partly, by extra-linguistic cues; it is fixed, invariably and unambiguously, by features of its context of use governed entirely by linguistic rules. We exploit the mechanisms of Centering and Coherence theories to develop a precise and general meta-semantics for pronouns, according to which the semantic value of a pronoun is determined by what is at the center of attention in a coherent discourse. Since the notions of attention and coherence are, we argue, governed by linguistic rules, we can give a uniform analysis of pronoun resolution that covers bound, demonstrative, and even discourse bound readings. Just as the semantic value of the first-person pronoun ‘I’ is conventionally set by a particular feature of its context of use—namely, the speaker—so too, we will argue, the semantic values of other pronouns, including ‘he’, are conventionally set by particular features of the context of use.

Our aim in the present paper is to investigate, from the standpoint of truth-theoretic semantics, English tense, temporal designators and quantifiers, and other expressions we use to relate ourselves and other things to the temporal order. Truth-theoretic semantics provides a particularly illuminating standpoint from which to discuss issues about the semantics of tense, and their relation to thoughts at, and about, times. Tense, and temporal modifiers, contribute systematically to conditions under which sentences we utter are true or false. A Tarski-style (...) truth-theoretic semantics, by requiring explicitly represented truth conditions, helps to sharpen questions about the function of tense, and to deepen our insight into the contribution the tenses and temporal modifiers make to what we say by using them.

In this paper, we defend Davidson's program in truth-theoretical semantics against recent criticisms by Scott Soames. We argue that Soames has misunderstood Davidson's project, that in consequence his criticisms miss the mark, that appeal to meanings as entities in the alternative approach that Soames favors does no work, and that the approach is no advance over truth-theoretic semantics.

This chapter identifies the central issue between Michael Dummett and Donald Davidson on the role of convention in language and argues they are not as far apart in the end as they take themselves to be.

This paper advances a general argument, inspired by some remarks of Davidson, to show that appeal to meanings as entities in the theory of meaning is neither necessary nor sufficient for carrying out the tasks of the theory of meaning. The crucial point is that appeal to meaning as entities fails to provide us with an understanding of any expression of a language except insofar as we pick it out with an expression we understand which we tacitly recognize to be (...) a translation of the term whose meaning we want to illuminate by the appeal to assigning to it a meaning. The meaning drops out as irrelevant: the work is done, and can only be done, by matching terms already understood with terms they translate. (shrink)

This article is a survey of the literature on context sensitivity in the philosophy of language.

There is a long tradition in philosophy and literary theory defending the view that engagement with literature promotes readers’ empathy. Until the last century, few of the empirical claims adduced in that tradition were investigated experimentally. Recent work in psychology and neuropsychology has now shed new light on the interplay of empathy and literature. This article surveys the experimental findings, addressing three central questions: What is it to read empathically? Does reading make us more empathic? What characteristics of literature, if (...) any, affect readers’ empathy? While experimental studies have delivered no conclusive answers to these questions, it has exposed their psychological complexity and constructed a more nuanced picture of the diverse ways in which literature interacts with our empathic capacities.

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

We argue that the trend toward providing users with feasible and actionable explanations of AI decisions—known as recourse explanations—comes with ethical downsides. Specifically, we argue that recourse explanations face several conceptual pitfalls and can lead to problematic explanation hacking, which undermines their ethical status. As an alternative, we advocate that explanations of AI decisions should aim at understanding.

With increased visibility of trans people comes increased philosophical interest in gendered language. This chapter aims to look at the research on gendered language in analytic philosophy of language so far, which has focused on two concerns: (1) determining how to define gender terms like ‘man’ and ‘woman’ such that they are trans inclusive and (2) if, or to what extent, we should use gendered language at all. We argue that the literature has focused too heavily on how gendered language (...) can harm trans people, and has not considered how trans people use gendered language to create meaning and joy for ourselves. Pulling from the literature in sociolinguistics, we look at examples of how trans people use language to make their lives better by gaining recognition, playing with gendered language, finding joy in gendered language, and taking control of definitional power, concluding that debates about gendered language need to consider not only how such language harms trans people but also how trans people use it for our own liberation.

This essay analyzes the provocative image of the bodhisattva, the saint of the Indian Mahayana Buddhist tradition, descending into the hell realms to work for the benefit of its denizens. Inspired in part by recent attempts to naturalize Buddhist ethics, I argue that taking this ‘mythological’ image seriously, as expressing philosophical insights, helps us better understand the shape of Mahayana value theory. In particular, it expresses a controversial philosophical thesis: the claim that no amount of physical pain can disrupt the (...) flourishing of a fully virtuous person. I reconstruct two related elements of early Buddhist psychology that help us understand this Mahayana position: the distinction between hedonic sensation and virtuous or nonvirtous mental states ; and the claim that humans are massively deluded as to what constitutes well-being. Doing so also lets me emphasize the continuity between early Buddhist and Mahayana traditions in their views on well-being and flourishing. (shrink)

The thought that empathy plays an important role in moral motivation is almost a platitude of contemporary folk psychology. Parallel themes were mooted in German moral philosophy and aesthetics in the 1700s, and versions of the empathy construct remained prominent in continental accounts of moral motivation through the nineteenth century and early twentieth centuries. This chapter elucidates the Empathic Motivation Hypothesis (EMH) and sets out some of the conceptual and empirical challenges it faces. It distinguishes empathic concern from other dimensions (...) of empathy (e.g., resonance, attunement, distress, and non-empathic concern) and examines the merits of EMH as a developmental thesis, focusing on evidence from psychopathology and attachment theory.

In this paper the propositional logic LTop is introduced, as an extension of classical propositional logic by adding a paraconsistent negation. This logic has a very natural interpretation in terms of topological models. The logic LTop is nothing more than an alternative presentation of modal logic S4, but in the language of a paraconsistent logic. Moreover, LTop is a logic of formal inconsistency in which the consistency and inconsistency operators have a nice topological interpretation. This constitutes a new proof of (...) S4 as being "the logic of topological spaces", but now under the perspective of paraconsistency. (shrink)

This essay considers the eighth century Indian Buddhist monk, Śāntideva’s strategy of using the afflictive mental states for progress towards liberation in his Introduction to the Practice of Awakening. I begin by contrasting two images from the first chapter that represent the power of bodhicitta: the fires destroying the universe at the end of time, and the mercury elixir that transmutes base metals into gold. The first of these, I argue, better illustrates the text’s predominant strategy of destroying the afflictive (...) mental states directly by their antidotes. The second, in contrast, represents an alternative strategy in which afflictive mental states like anger, craving and delusion, are manipulated for liberative gain. I offer several examples of Śāntideva’s use of the kleśas in his text, and argue that they can be understood as a continuation of the logic of skillful means, in which destructive actions, and here destructive mental states, are used to lessen suffering. Finally, I suggest that one reason Śāntideva employs the kleśas in this way is because of his realization that many practitioners early on the bodhisattva path will lack the motivation necessary to successfully pursue the difficult training of the bodhisattva.

The causal theory of action has been the standard view in the philosophy of action and mind. In this chapter, I will present responses to two challenges to the theory. The first says, basically, that there is no positive argument in favour of the causal theory, as the only reason that supports it consists in the apparent lack of tenable alternatives. The second challenge says that the theory fails to capture the phenomenon of agency, as it reduces activity to mere (...) happenings (events and event-causal processes). This is often referred to as the problem of "disappearing agency". My main aim is to show that there is no problem of disappearing agency, and we will see that my response to the first challenge will be conducive to this end. I will present a positive argument for the causal theory on the basis of considerations concerning the metaphysics of agency, and I will suggest that we "own" the agency that springs from our mental states and events "by default".

Few notions are more central to Aquinas’s thought than those of matter and form. Although he invokes these notions in a number of different contexts, and puts them to a number of different uses, he always assumes that in their primary or basic sense they are correlative both with each other and with the notion of a “hylomorphic compound”—that is, a compound of matter (hyle) and form (morphe). Thus, matter is an entity that can have form, form is an entity (...) that can be had by matter, and a hylomorphic compound is an entity that exists when the potentiality of some matter to have form is actualized.1 What is more, Aquinas assumes that the matter of a hylomorphic compound explains certain of its general characteristics, whereas its form explains certain of its more specific characteristics. Thus, the matter of a bronze statue explains the fact that it is bronze, whereas its form explains the fact that it is a statue. Again, the matter of a human being explains the fact that it is a material object, whereas its form explains the specific type of material object it is (namely, human). My aim in this chapter is to provide a systematic introduction to Aquinas’s primary or basic notions of matter and form. To accomplish this aim, I focus on the two main theoretical contexts in which he deploys them—namely, his theory of change and his theory of individuation. In both contexts, as we shall see, Aquinas appeals to matter and form to account for relations of sameness and difference holding between distinct individuals. (shrink)

This paper proposes and defends an account of what it is to act for reasons. In the first part, I will discuss the desire-belief and the deliberative model of acting for reasons. I will argue that we can avoid the weaknesses and retain the strengths of both views, if we pursue an alternative according to which acting for reasons involves taking something as a reason. In the main part, I will develop an account of what it is to take something (...) as a reason for action. On the basis of this, I will then offer a new account of what it is to act for reasons.

Properties have an important role in specifying different views on laws of nature: virtually any position on laws will make some reference to properties, and some of the leading views even reduce laws to properties. This chapter will first outline what laws of nature are typically taken to be and then specify their connection to properties in more detail. We then move on to consider three different accounts of properties: natural, essential, and dispositional properties, and we shall see that different (...) conceptions of properties also result in different views of the modal status of laws, such as the question of whether laws are metaphysically necessary or contingent. Finally, there are also important links specifically between properties, natural kinds, and laws of nature that deserve our attention. (shrink)

De uma perspectiva comportamentalista radical, o eu é um repertório verbal complexo, que, como tal, tem uma gênese social. O reconhecimento da origem social do “eu” abre caminho para uma análise política, incluindo uma discussão do pa- pel das relações de poder na constituição do eu. Entretanto, uma concepção radicalmente social do “eu”, como a proposta pelo comportamentalismo, suscita um problema político: se o eu é integralmente produto do ambiente social, de onde viria uma eventual “vontade” de romper com esse (...) sistema? Parece que para reconhecer a possibilidade de ação política transformadora seria preciso preservar uma noção descontextualizada de “eu”. Considerando essa dificuldade, o objetivo deste artigo é propor uma interpretação política da constituição do “eu” no âmbito do comportamentalismo radical, mantendo no horizonte a possibilidade de uma ação política transformadora. Para tanto, destacamos como “eus” oprimidos são tornados submissos, mas também como de certas contingências podem emergir “eus” subversivos, que se opõem a um sistema social opressivo. Esse “eu” subversivo é caracterizado por um repertório de autoconhecimento mais amplo, que inclui a discriminação do papel das relações de poder e do controle promovido por instituições. Concluímos, com isso, que um “eu” socialmente constituído pode ser politicamente ativo. (shrink)

Quilty-Dunn et al.'s wide-ranging defense of the Language of Thought Hypothesis (LoTH) argues that vision traffics in abstract, structured representational formats. We agree: Vision, like language, is compositional – just as words compose into phrases, many visual representations contain discrete constituents that combine in systematic ways. Here, we amass evidence extending this proposal, and explore its implications for how vision interfaces with the rest of the mind.

In this article, I examine the moral dimensions of gender affirmation. I argue that the moral value of gender affirmation is rooted in what Iris Murdoch called loving attention. Loving attention is central to the moral value of gender affirmation because such affirmation is otherwise too fragile or insincere to have such value. Moral reasons to engage in acts that gender affirm derive from the commitment to give and express loving attention to trans people as a way of challenging their (...) marginalization. In the latter part of the paper, I will discuss how my arguments bear on recent arguments by Robin Dembroff and Daniel Wodak (2018) on the use of gender-neutral language. They argue that we have a duty not to use gender-specific pronouns for anyone. Their conclusion turns, in part, on a rejection of gender affirmation as a moral duty. The value of gender affirmation, rooted in our moral perception of trans people, should make us skeptical of this conclusion, in favor of a more nuanced and pluralistic approach to the ethics of gendering.

The metaphysics of gender and race is a growing area of concern in contemporary analytic metaphysics, with many different views about the nature of gender and race being submitted and discussed. But what are these debates about? What questions are these accounts trying to answer? And is there real disagreement between advocates of differ- ent views about race or gender? If so, what are they really disagreeing about? In this paper I want to develop a view about what the debates (...) in the metaphysics of gender and race are about, namely, a version of metaphysical deflationism, according to which these debates are about how we actually use or should use the terms ‘gender’ and ‘race’ (and other related terms), where moral and political considerations play a central role. I will also argue that my version of the view can overcome some recent and powerful objections to metaphysical deflationism of- fered by Elizabeth Barnes (2014, 2017). (shrink)

Upshot: In our response we focus on five questions that point to important common themes in the commentaries: why start in wicked problems, what kind of system is a scientific perspective, what is the nature of second-order research processes, what does this mean for understanding interdisciplinary work, and how may polyocular research help make real-world decisions.

I present a discussion of some issues in the ontology of spacetime. After a characterisation of the controversies among relationists, substantivalists, eternalists, and presentists, I offer a new argument for rejecting presentism, the doctrine that only present objects exist. Then, I outline and defend a form of spacetime realism that I call event substantivalism. I propose an ontological theory for the emergence of spacetime from more basic entities. Finally, I argue that a relational theory of pre-geometric entities can give rise (...) to substantival spacetime in such a way that relationism and substantivalism are not necessarily opposed positions, but rather complementary. In an appendix I give axiomatic formulations of my ontological views. (shrink)

Human nature has always been a foundational issue for philosophy. What does it mean to have a human nature? Is the concept the relic of a bygone age? What is the use of such a concept? What are the epistemic and ontological commitments people make when they use the concept? In What’s Left of Human Nature? Maria Kronfeldner offers a philosophical account of human nature that defends the concept against contemporary criticism. In particular, she takes on challenges related to social (...) misuse of the concept that dehumanizes those regarded as lacking human nature (the dehumanization challenge); the conflict between Darwinian thinking and essentialist concepts of human nature (the Darwinian challenge); and the consensus that evolution, heredity, and ontogenetic development results from nurture and nature. After answering each of these challenges, Kronfeldner presents a revisionist account of human nature that minimizes dehumanization and does not fall back on outdated biological ideas. Her account is post-essentialist because it eliminates the concept of an essence of being human; pluralist in that it argues that there are different things in the world that correspond to three different post-essentialist concepts of human nature; and interactive because it understands nature and nurture as interacting at the developmental, epigenetic, and evolutionary levels. On the basis of this, she introduces a dialectical concept of an ever-changing and “looping” human nature. Finally, noting the essentially contested character of the concept and the ambiguity and redundancy of the terminology, she wonders if we should simply eliminate the term “human nature” altogether.

The ability to perceive the shapes of things as enduring through changes in how they stimulate our sense organs is vital to our sense of stability in the world. But what sort of capacity is shape constancy, and how is it reflected in perceptual experience? This paper defends a pluralist account of shape constancy: There are multiple kinds of shape constancy centered on geometrical properties at various levels of abstraction, and properties at these various levels feature in the content of (...) perceptual experience, governing patterns of apparent shape similarity. I propose that the varieties of shape constancy are subserved by the syntactic complexity of perceptual shape representations. By assigning discrete constituents to various abstract shape parameters, these representations attune us to the preservation of certain abstract shape properties through changes in more determinate shape properties. Finally, I draw broader lessons concerning the nature and function of perceptual constancy. (shrink)

Feminists note an association of arguing with aggression and masculinity and question the necessity of this connection. Arguing also seems to some to identify a central method of philosophical reasoning, and gendered assumptions and standards would pose problems for the discipline. Can feminine modes of reasoning provide an alternative or supplement? Can overarching epistemological standards account for the benefits of different approaches to arguing? These are some of the prospects for argumentation inside and outside of philosophy that feminists consider. -/- (...) The further concern is that the academic study of argumentation – in philosophy and other disciplines – has failed to account for the type of reasoning needed for social justice movements. What resources for addressing these concerns can be found in informal logic and interdisciplinary argumentation theory? Since part of the perceived problem derives from assuming that arguing is a contest, are more collaborative epistemological frameworks better? Can regular politeness or civility hedge against undesirable tendencies of argumentation? Can “critical thinking” pedagogy involving argument educations answer the needs of social justice? (shrink)

Predication is an indisputable part of our linguistic behavior. By contrast, the metaphysics of predication has been a matter of dispute ever since antiquity. According to Plato—or at least Platonism, the view that goes by Plato’s name in contemporary philosophy—the truths expressed by predications such as “Socrates is wise” are true because there is a subject of predication (e.g., Socrates), there is an abstract property or universal (e.g., wisdom), and the subject exemplifies the property.1 This view is supposed to be (...) general, applying to all predications, whether the subject of predication is a person, a planet, or a property.2 Despite the controversy surrounding the metaphysics of predication, many theistic philosophers—including the majority of contemporary analytic theists—regard Platonism as extremely attractive. At the same time, however, such philosophers are also commonly attracted to a form of traditional theism that has at its core the thesis that God is an absolutely independent.. (shrink)

It is generally agreed that one of the key differences between ancient skepticism and modern and contemporary skepticism is that the ancient skeptic does not call into question the existence of the external world, but only our ability to know the properties or qualities of external objects. In this paper, I argue that in Sextus Empiricus's attack on the Epicurean criterion of truth one finds evidence that the ancient Pyrrhonist also suspends judgment about the existence of external objects.

A supertask consists in the performance of an infinite number of actions in a finite time. I show that any attempt to carry out a supertask will produce a divergence of the curvature of spacetime, resulting in the formation of a black hole. I maintain that supertaks, contrarily to a popular view among philosophers, are physically impossible. Supertasks, literally, collapse under their own weight.

Several scholars familiar with Sextus Empiricus’s Pyrrhonism who have attentively read his Against the Ethicists have gotten the impression that something strange is going on in this book. For, at variance with the ‘official’ Pyrrhonian attitude of universal suspension of judgment, a number of passages of Against the Ethicists seem to ascribe to the Pyrrhonist both a type of negative dogmatism and a form of realism, which together amount to what may be called ‘moderate ethical realism’. The purpose of this (...) paper is to determine whether Sextus does embrace such a position in Against the Ethicists. (shrink)

A prominent view holds that perception and memory are distinguished at least partly by their temporal orientation: Perception functions to represent the present, while memory functions to represent the past. Call this view perceptual presentism. This chapter critically examines perceptual presentism in light of contemporary perception science. I adduce evidence for three forms of perceptual sensitivity to the past: (i) shaping perception by past stimulus exposure, (ii) recruitment of mnemonic representations in perceptual processing, and (iii) perceptual representation of present objects (...) as possessing past properties. I argue that forms (i) and (ii) are consistent with perceptual presentism, while form (iii) poses a genuine threat to the view. While the empirical case for form (iii) remains inconclusive, I suggest that the most serious challenges to perceptual presentism derive from representations that integrate mnemonic and present-tensed elements in the performance of canonical perceptual functions, such as perceiving object continuity over time.

Traditional approaches to conflict are oriented towards establishing (or re-establishing) consensus, either in the form of a resolution of the conflict or in the form of an ‘agree-to-disagree’ standstill between the stakeholders. In this paper, we criticize these traditional approaches, each for specific reasons, and we propose and develop the agonistic approach to conflict. Based on Chantal Mouffe’s agonistic democratic theory, the agonistic approach to conflict is more welcoming of dissensus, replacing discussion stoppers with discussion starters and replacing standstills with (...) contestation. We illustrate such replacements and develop this approach, we analyse technological conflicts in a concrete R&D setting: the global hydrogen economy. From this context, we focus on the conflict between the proponents of blue hydrogen (drawn from fossil fuels) and those of green hydrogen (created through electrolysis). We conclude by highlighting the advantage of the agonistic approach but also drawing attention to its own specific risk, namely, antagonism. (shrink)

According to the standard view in philosophy, intentionality is the mark of genuine action. In psychology, human cognition and agency are now widely explained in terms of the workings of two distinct systems (or types of processes), and intentionality is not a central notion in this dual-system theory. Further, it is often claimed, in psychology, that most human actions are automatic, rather than consciously controlled. This raises pressing questions. Does the dual-system theory preserve the philosophical account of intentional action? How (...) much of our behavior is intentional according to this view? And what is the role of consciousness? I will propose here a revised account of intentional action within the dual-system framework, and we will see that most of our behavior can qualify as intentional, even if most of it is automatic. An important lesson will be that philosophical accounts of intentional action need to pay more attention to the role of consciousness in action. (shrink)

This article develops a view of shape representation both in visual experience and in subpersonal visual processing. The view is that, in both cases, shape is represented in a ‘layered’ manner: an object is represented as having multiple shape properties, and these properties have varying degrees of abstraction. I argue that this view is supported both by the facts about visual phenomenology and by a large collection of evidence in perceptual psychology. Such evidence is provided by studies of shape discriminability, (...) apparent motion, multiple-object tracking, and structure-from-motion. Recent neuroscientific work has also corroborated this psychophysical evidence. Finally, I draw out implications of the layered view for processes of concept acquisition. 1 Introduction2 Metric Properties andShape Properties3 Metric Views4 Against Metric Views of Visual Shape Experience5 The Visual System Uses Abstract Shape Properties6 Against Metric Views of Visual Shape Representation7 Neural Underpinnings of Abstract Shape Perception8 Implications.

Causal closure arguments against interactionist dualism are currently popular amongst physicalists. Such an argument appeals to some principles of the causal closure of the physical, together with certain other premises, to conclude that at least some mental events are identical with physical events. However, it is crucial to the success of any such argument that the physical causal closure principle to which it appeals is neither too strong nor too weak by certain standards. In this paper, it is argued that (...) various forms of naturalistic dualism, of an emergentist character, are consistent with the strongest physical causal closure principles that can plausibly be advocated.
