RÉSUMÉ: Le point de vue de Davidson sur les concepts de croyance et de signification implicites dans nos pratiques d’attribution de croyance et de signification peut à bon droit être mis à l’épreuve par une élucidation de ses rapports avec la psychologie empirique. Mais une telle mise à l’épreuve n’a de valeur que si elle confronte d’abord l’id’e reçue voulant que sa position a peu ou pas de liens avec l’etude empirique du développement cognitif. Je défends ici une approche du (...) point de vue de Davidson qui montre clairement en quoi une vaste gamme de découvertes empiriques en psychologie du développement -- souvent considérées comme non pertinentes, voire comme incompatibles, avec son enquête conceptuelle -- est en fait fort pertinente et en harmonie avec lui.

One of the main contributions of philosophers at the end of the 19th century and beginning of the 20th century to philosophy of science and semantics was the thesis inspired in the scientific advances of natural and exact sciences, that there is not a single true theory of what goes on in the empirical world, but rather the possibility of constructing multiple versions, equally satisfactory, of an explanation of the world. In the Vienna Circle, more specifically, the conventionalist movement showed (...) its influence primarily in the writings of Neurath, but also, more subtly, in the texts of Carnap. In this paper, I shall examine the theoretical relations between Quine’s holistic thesis and the conventionalist aspects of his work. In order to do this I will discuss Neurath’s holistic coherentism and of the conventionalist and holistic aspects present in Camap’s work, which merge, mainly in the Aufbau, with reduc-tionist aims. Thus, I intend to help to clarify to what extent Quine’s holism depends on a conventionalist position and to what extent conventionalism, in its turn, can get along with reductionist epistemological remains.

In this article, I seek to assess the extent to which a ‘trope-theoretic’ version of Theism is a better theory than that of a theory of Atheism, as posited by Graham Oppy. This end will be achieved by utilising the systemisation of the theoretical virtues proposed by Michael Keas (as further modified by an application of the work of Jonathan Schaffer), the notion of a trope, introduced by D.C. Williams, and an aspect, proposed by Donald L.M. Baxter, which will establish (...) the basis of the trope-theoretic account of Theism that will be at the centre of our analysis. This assessment will ultimately show that Theism, rather than that of Atheism (Naturalism), can successfully achieve the trade-off between minimising theoretical commitments and maximising explanatory power. And thus, given this, the best theory of Theism—namely, that of ‘trope-theoretic Theism’—is to be privileged over that of the best theory of Atheism—namely, that of ‘Oppyian Naturalism’—and is able to provide grounds for a decisive reassessment of the cogency of Agnosticism.

This paper is divided into three sections. It aims to give some resources for making possible a straightforward debate on the mind-body problem as well as some serious researches in it. Having these goals into account, the first section offers an introduction to the mind-body problem and the second section explains briefly some of the most influential answers to this problem. The third section is devoted to eliminative materialism.

This paper discusses the possible inspirations that might be derived from the viewpoints of Eastern Philosophy in contemporary studies of consciousness. First of all, two notions of consciousness are introduced, one of which can be explained by science. The other however cannot, and as such is also called the ‘Hard Problem’. Secondly, the special features shared by morality and the ‘Hard Problem of Consciousness’ are discussed. Thirdly, I discuss the conventional routes Oriental philosophy takes toward an exploration of the human (...) mind, and consequently point out that Oriental philosophy views consciousness as the fundamental feature of moral beings. One of the reasons that human beings can pursue meaningful life is because of the necessary existence of conscious experience. It is our conscious experience that makes a life of value possible. Therefore, in Oriental philosophy matters of consciousness revolve around aspects of morality and spirituality, and the training of the abilities of consciousness is emphasized over knowledge. Finally, this paper concludes with a comparison of the different approaches Oriental philosophy and current Western academics take in their study of consciousness. Hopefully, one day consciousness can be fully explored from more diverse viewpoints to gain a more comprehensive understanding and so further the happiness of humanity. (shrink)

Husserl offers insight into the constituting of the self-aware ego through time-consciousness. Yet his account does not satisfactorily explain how this ego can experience itself as presently acting. Furthermore, although he acknowledges that the Now is not a knife-edge present, he does not show what determines its duration. These shortfalls and others are overcome through a change of starting point. Citing empirical evidence, I take it as a basic given that when a caregiver frontally engages an infant of two months (...) or so, the infant is aware of a person attending. The attending, I propose, is experienced by the infant as having an implicit target, a focal center. In the infant’s awareness, the carer’s focal center is the self. When a You is perceived as attending, a self is apperceived. I argue that such dependence on a You’s attending continues lifelong in derivative forms. I explore the idea that original time is a partial oscillation of awareness between the perceived You and the apperceived self. I then show how, from this oscillation, the ordinary experience of time is derived. (shrink)

Rastrearemos a refutação da necessidade de fundamentos ontológicos para teorias éticas de Putnam analisando sua trajetória por autores como Quine, Moore e Wittgenstein. Partiremos do naturalismo epistemológico de Quine para estabelecer sua base coerentista pragmática. Então, investigaremos seu distanciamento da ontologia conforme sua perspectiva wittgensteiniana do conceitualismo mooreano e platônico. Caracterizando Heidegger como alvo primário de sua crítica a uma necessidade de ontologia, afasta-se mesmo de Quine ao abraçar uma relatividade conceitual inspirada na mereologia e em jogos de linguagem para (...) estabelecer a objetividade da ética sem a necessidade de objetos. Por fim, a partir dessa definição, investigaremos a concepção de ética segundo Putnam, fortemente inspirada em Dewey e Aristóteles em diálogo com Levinas e Kant em prol de um “florescimento cognitivo humano”. Sua definição é breve e superficial, todavia clama que tais características sejam necessárias a fim de dar maleabilidade à ética, em contraponto a uma definição rígida e facilmente quebradiça tendo em vista o amplo descordo presente na filosofia moral. Esta flexibilidade não cairia em relativismo absoluto uma vez que preza a razoabilidade e progresso, assim como evitaria doutrinas danosas “anti-florescimento”. (shrink)

According to a two-level criterion for combination tests in the field of ordinary language, moral 'ought'-sentences may be taken to imply 'I intend'-sentences partly semantically and partly pragmatically. If so, a trenchant linguistic analysis of the concept of moral obligation cannot do without a non-classical logic which allows to model these important kinds of ordinary-language implications by means of purely syntactical derivations. For this purpose, an integrated logic of conviction and intention has been tentatively devised by way of a doxastically, (...) buletically, and pragmatically extended calculus of natural deduction. This system of buletic logic cannot even be launched without one or two derivation rules of deductive closedness. However, these very closedness rules appear to be responsible for buletic paradoxes which are analogous to paradoxes long since known from other, less exotic branches of logic but at first sight look much more virulent. After having scrutinized two potential strategies for coping with the paradoxes of buletic logic, finally we can convince ourselves that these paradoxes, as well as their familiar non-buletic counterparts, are but apparent paradoxes, provided we consistently lean on C-CT and do not let pragmatical considerations intrude into purely logical ones.

A common method of improving how well understood a theory is, is by comparing it to another theory which has been better developed. Radical interpretation is a theory which attempts to explain how communication has meaning. Radical interpretation is treated as another time dependent theory and compared to the time dependent theory of biological evolution. Several similarities and differences are uncovered. Biological evolution can be gradual or punctuated. Whether radical interpretation is gradual or punctuated depends on how the question is (...) framed: on the coarse-grained time scale it proceeds gradually, but on the fine-grained time scale it proceeds by punctuated equilibria. Biological evolution proceeds by natural selection, the counterpart to this is the increase in both correspondence and coherence. Exaption, mutations, and spandrels have counterparts metaphor, speech errors, and puns respectively. Homologous and analogs have direct counterparts in specific words. The most important differences originate from the existence of a unit of inheritance occurring in biological evolution - there is no such unit in language. (shrink)

In the recent literature on all things metaontological, discussion of a notorious Meinongian doctrine—the thesis that some objects have no kind of being at all—has been conspicuous by its absence. And this is despite the fact that this thesis is the central element of the noneist metaphysics of Richard Routley (1980) and Graham Priest (2005). In this paper, we therefore examine the metaontological foundations of noneism, with a view to seeing exactly how the noneist's approach to ontological inquiry differs from (...) the orthodox Quinean one. We proceed by arguing that the core anti-Quinean element in noneism has routinely been misidentified: rather than concerning Quine's thesis that to be is to be the value of a variable, the real difference is that the noneist rejects what we identify as Quine's “translate-and-deflate” methodology. In rejecting this aspect of Quinean orthodoxy, the noneist is in good company: many of those who think that questions of fundamentality should be the proper focus of ontological inquiry can be read as rejecting it too. Accordingly, we then examine the differences between the noneist's conception of ontology and that offered by the fundamentalist. We argue that these two anti-Quinean approaches differ in terms of their respective conceptions of the theoretical role associated with the notion of being. And the contrast that emerges between them is, in the end, an explanatory one. (shrink)

Cognitive theorists routinely disagree about the evidence supporting claims in cognitive science. Here, we first argue that some disagreements about evidence in cognitive science are about the evidence available to be drawn upon by cognitive theorists. Then, we show that one’s explanation of why this first kind of disagreement obtains will cohere with one’s theory of evidence. We argue that the best explanation for why cognitive theorists disagree in this way is because their evidence is what they rationally grant. Finally, (...) we explain why our view does not lead to a pernicious kind of relativism in cognitive science. (shrink)

Some alethic pluralists maintain that there are two kinds of truths operant in our alethic discourse: a realist kind and an anti-realist kind. In this paper, we argue that such a binary conception cannot accommodate certain social truths, specifically truths about race. Most alethic pluralists surprisingly overlook the status of racial truths. Douglas Edwards is, however, an exception. In his version of alethic pluralism—Determination Pluralism—racial truths are superassertible (anti-realist) true rather than correspondence (realist) true. We argue that racial truths exhibit (...) features of both superassertibility (anti-realism) and correspondence (realism). This suggests a fuzzy boundary between realist and anti-realist kinds of truth. There may be a continuum rather than a dichotomy of truths. We conclude by sketching one way for alethic pluralists to accommodate such a notion. (shrink)

Using Carnap’s concept explication, we propose a theory of concept formation in mathematics. This theory is then applied to the problem of how to understand the relation between the concepts formal proof and informal, mathematical proof.

This volume is about abstract objects and the ways we refer to them in natural language. Asher develops a semantical and metaphysical analysis of these entities in two stages. The first reflects the rich ontology of abstract objects necessitated by the forms of language in which we think and speak. A second level of analysis maps the ontology of natural language metaphysics onto a sparser domain--a more systematic realm of abstract objects that are fully analyzed. This second level reflects the (...) commitments of real metaphysics. The models for these commitments assign truth conditions to natural language discourse.

In his discussion note ‘J. J. C. Smart, Materialism and Occam's Razor’ Peter Glassen argues that it was inconsistent of me both to assert that realism is true and that Occam's razor is a reason for the materialist thesis. Glassen says that Occam's razor ‘ is not a physical thing, state or process at all ’. A little further down on the same page he uses the phrase ‘material or physical thing, state, or process’. It is possible, therefore, that Glassen (...) regards the distinction between ‘material’ and ‘physical’ as unimportant in the present context. I think however that one way of replying to Glassen turns on this distinction. (shrink)

An introduction to the theories of endurantism and perdurantism, and persistence more broadly.

Particle indistinguishability has always been considered a purely quantum mechanical concept. In parallel, indistinguishable particles have been thought to be entities that are not properly speaking objects at all. I argue, to the contrary, that the concept can equally be applied to classical particles, and that in either case particles may (with certain exceptions) be counted as objects even though they are indistinguishable. The exceptions are elementary bosons (for example photons).

The identity and diversity of individual objects may be grounded or ungrounded, and intrinsic or contextual. Intrinsic individuation can be grounded in haecceities, or absolute discernibility. Contextual individuation can be grounded in relations, but this is compatible with absolute, relative or weak discernibility. Contextual individuation is compatible with the denial of haecceitism, and this is more harmonious with science. Structuralism implies contextual individuation. In mathematics contextual individuation is in general primitive. In physics contextual individuation may be grounded in relations via (...) weak discernibility. (shrink)

One of the salient developments in recent metaphysics is the increasing popularity of material plenitude: roughly, the thesis that wherever there is one material object there is in fact a great multitude of co-located but numerically distinct objects that differ principally in which of their properties they have essentially and which accidentally. Here I argue that we have at least as much reason to look favorably on event plenitude: wherever one event occurs there occur a great multitude of co-located but (...) numerically distinct events that differ principally in which of their properties they have essentially and which accidentally. I argue, first, that the standard reasons to adopt material plenitude extend fairly straightforwardly to events, and secondly, that only event plenitude can protect the plausible idea that causality is an extensional relation.

This dissertation is an experiment: what happens if we treat proper names as anaphoric expressions on a par with pronouns? The first thing to notice is that a name's 'antecedent' can occur in a discourse prior to the one containing the name. An individual may be introduced and tagged with a name in one context, and then retrieved using the name in a later context. To allow for discourse crossing anaphora, in addition to the usual cross-sentential anaphora, a revision of (...) discourse semantics is in order. Essentially, we must countenance discourse referents that span contexts, and think of contexts, not as islands, but as nodes connected to each other by the discourse referents they share. Discourse semantics gives rise to a new notion of content determined by discourse reference rather than pure reference. In a space of contexts structured by shared discourse referents, discourse content becomes transmissable. For a piece of content may be sent from one context to another whenever the discourse referents bundled up in the content are held in common by the two contexts. The final step is to treat the cognitive state of an agent as just another kind of context, and so a potential recipient of discourse content. Discourse content is more fine-grained than traditional 'singular' content, and so is a better fit for our pretheoretic intuitions about communication and attitude reporting. This is illustrated by applying the theory to Frege's puzzle, a puzzle of Loar's about communication, Kripke's puzzle about belief, Geach's intentional identity and new breed of 'mixed' de re-de dicto sentence.

A priori reflection, common sense and intuition have proved unreliable sources of information about the world outside of us. So the justification for a theory of the categories must derive from the empirical support of the scientific theories whose descriptions it unifies and clarifies. We don’t have reliable information about the de re modal profiles of external things either because the overwhelming proportion of our knowledge of the external world is theoretical—knowledge by description rather than knowledge by acquaintance. This undermines (...) the traditional idea that to be an object of category C is to be an object with such- and-such characteristic possibilities of combination. But this is no loss because de re modal thought lacks utility for creatures like us. (shrink)

The paper presents a dilemma for both epistemic and non-epistemic versions of conceivability-based accounts of modal knowledge. On the one horn, non-epistemic accounts do not elucidate the essentialist knowledge they would be committed to. On the other, epistemic accounts do not elucidate everyday life de re modal knowledge. In neither case, therefore, do conceivability accounts elucidate de re modal knowledge.

Two related claims have lately garnered currency: dispositional essentialism—the view that some or all properties, or some or all fundamental properties, are essentially dispositional; and the claim that laws of nature (or again, many or the fundamental ones) are metaphysically necessary. I have argued elsewhere (On the metaphysical contingency of laws of nature, Oxford University Press, Oxford, 2002) that the laws of nature do not have a mind-independent metaphysical necessity, but recent developments on dispositions have given these ideas a new (...) vibrancy and made them the topic of more focused discussion. So I would like to revisit this, arguing that the new work, as interesting and important as it is to our understanding of fundamental properties, powers and dispositions, should not change our minds about metaphysical necessity. One should still think necessity is conceptually or conventionally grounded. I do not argue that laws of nature are not necessary, nor that properties do not have dispositional essences, but only that if these are the case, then, like other de re or empirical necessities, they have no metaphysical weight and are based in our rules or decisions about how to talk about the world. We may have excellent reasons to talk and think in this way—but these reasons do not include, require or provide evidence of mind-independent metaphysical necessity or essences. (shrink)

This is part I of a two-part essay introducing case-intensional first order logic, an easy-to-use, uniform, powerful, and useful combination of first-order logic with modal logic resulting from philosophical and technical modifications of Bressan’s General interpreted modal calculus. CIFOL starts with a set of cases; each expression has an extension in each case and an intension, which is the function from the cases to the respective case-relative extensions. Predication is intensional; identity is extensional. Definite descriptions are context-independent terms, and lambda-predicates (...) and -operators can be introduced without constraints. These logical resources allow one to define, within CIFOL, important properties of properties, viz., extensionality and absoluteness, Bressan’s chief innovation that allows tracing an individual across cases without recourse to any notion of “rigid designation” or “trans-world identity.” Thereby CIFOL abstains from incorporating any metaphysical principles into the quantificational machinery, unlike extant frameworks of quantified modal logic. We claim that this neutrality makes CIFOL a useful tool for discussing both metaphysical and scientific arguments involving modality and quantification, and we illustrate by discussing in diagrammatic detail a number of such arguments involving the extensional identification of individuals via absolute properties, essential properties, de re vs. de dicto, and the results of possible tests.

Reanimated for the contemporary literature in the writings of Quine, [16]) and Kuhn [7], the conventionalism of Duhem [2] and Poincaré [12] has emerged in the last few years as one of the genuinely interesting topics in the philosophy of science. The theory in question—let us follow Grünbaum [3] in calling it the D-thesis, after its founder, Pierre Duhem—claims three things: a single scientific hypothesis H is never disconfirmable in isolation from its fellow; every single hypothesis H of science presupposes, (...) explicitly or implicitly, the support of a conjunction A = A, • A2 • … • Am of auxiliary assumptions or hypotheses; the failure of an observational consequence of H in face of contradictory evidence disconfirms only the conjunction of H and A, not H alone—i.e. establishes only ∼. The logical picture is as follows. (shrink)

This paper provides an exposition of the structuralist approach to underdetermination, which aims to resolve the underdetermination of theories by identifying their common theoretical structure. Applications of the structuralist approach can be found in many areas of philosophy. I present a schema of the structuralist approach, which conceptually unifies such applications in different subject matters. It is argued that two classic arguments in the literature, Paul Benacerraf’s argument on natural numbers and W. V. O. Quine’s argument for the indeterminacy of (...) translation, can be analyzed as instances of the structuralist schema. These two applications illustrate different kinds of conclusions that can be drawn through the structuralist approach; Benacerraf’s argument shows that we can derive an ontological conclusion about the given subject matter, while Quine’s structuralist approach leads to a semantic conclusion about how to determine linguistic meanings given radical translation. Then, as a case study, I review a recent debate in metaphysics between Shamik Dasgupta, Jason Turner, and Catharine Diehl to consider the extent to which different instances of the structuralist schema are conceptually unified. Both sides of the debate can be interpreted as utilizing the structuralist approach; one side uses the structuralist approach for an ontological conclusion, while the other side relies on a semantic conclusion. I argue that this has a strong dialectical consequence, which sheds light on the conceptual unity of the structuralist approach. (shrink)

For millennia self has been conjectured to be necessary for consciousness. But scant empirical evidence has been adduced to support this hypothesis. Inconsistent explications of “self” and failure to design apt experiments have impeded progress. Advocates of phenomenological psychiatry, however, have helped explicate “self,” and employed it to explain some psychopathological symptoms. In those studies, “self” is understood in a minimalist sense, sheer “for-me-ness.” Unfortunately, explication of the “minimal self” (MS) has relied on conceptual analysis, and applications to psychopathology have (...) been hermeneutic, allowing for many degrees of interpretive latitude. The result is that MS’s current scientific status is analogous to that of the “atom,” at the time when “atom” was just beginning to undergo transformation from a philosophical to a scientific concept. Fortunately, there is now an opportunity to promote a similar transformation for “MS.” Discovery of the brain’s Default Mode Network (DMN) opened the door to neuroimaging investigations of self. Taking the DMN and other forms of intrinsic activity as a starting point, an empirical foothold can be established, one that spurs experimental research and that enables extension of research into multiple phenomena. New experimental protocols that posit “MS” can help explain phenomena hitherto not thought to be related to self, thereby hastening development of a mature science of self. In particular, targeting phenomena wherein consciousness is lost and recovered, as in some cases of Unresponsive Wakefulness Syndrome (UWS), allow for design of neuroimaging probes that enable detection of MS during non-conscious states. These probes, as well as other experimental protocols applied to NREM Sleep, General Anesthesia (GA), and the waking state, provide some evidence to suggest that not only can self and consciousness dissociate, MS might be a necessary precondition for conscious experience. Finally, these findings have implications for the science of consciousness: it has been suggested that “levels of consciousness” (LoC) is not a legitimate concept for the science of consciousness. But because we have the conceptual and methodological tools with which to refine investigations of MS, we have the means to identify a possible foundation—a bifurcation point—for consciousness, as well as the means by which to measure degrees of distance from that foundation. These neuroimaging investigations of MS position us to better assess whether LoC has a role to play in a mature science of consciousness. (shrink)

Neuroscience can relate to ethics and normative issues via the brain’s cognitive control network. This network accomplishes several executive processes, such as planning, task-switching, monitoring, and inhibiting. These processes allow us to increase the accuracy of our perceptions and our memory recall. They also allow us to plan much farther into the future, and with much more detail than any of our fellow mammals. These abilities also make us fitting subjects for responsibility claims. Their activity, or lack thereof, is at (...) the heart of culpability. For instance, planning to kill someone is strong evidence of what the law calls mens rea—a guilty mind. Claims about norms, or ethical “should” claims, express two-level propositions, directed at the behaving person at one level, and at that person’s mind and cognitive control network at another level. Thus, “People should stop themselves from hurting others,” is a claim about how people should behave and also a claim about how their cognitive control networks should behave—i.e., they should inhibit harmful behavior, or the intentions leading up to it. Planning is both an ability of the full person, and of that person’s mind. Neuroscience affirms the common notion, seen both in law and folk psychology, that what makes us guilty or culpable are certain events and states that exist in our minds. Overt behavior, including speech, is fallible evidence of these states and processes. Cases of negligence still involve the executive processes, but “negatively,” in that negligence results when certain types of executive activity fail to take place. (shrink)

Theories of phenomenal intentionality have been claimed to resolve certain worries about the indeterminacy of mental content that rival, externalist theories face. Thus far, however, such claims have been largely programmatic. This paper aims to improve on prior arguments in favor of phenomenal intentionality by using attention and Gestalt principles as specific examples of factors that influence the phenomenal character of perceptual experience in ways that thereby help determine perceptual content. Some reasons are then offered for rejecting an alternative interpretation (...) of these examples, according to which the phenomenal effects of attention and Gestalt principles play no role in the determination of perceptual content.

There are two families of influential and stubborn puzzles that many theories of aboutness (intentionality) face: underdetermination puzzles and puzzles concerning representations that appear to be about things that do not exist. I propose an approach that elegantly avoids both kinds of puzzle. The central idea is to explain aboutness (the relation supposed to stand between thoughts and terms and their objects) in terms of relations of co-aboutness (the relation of being about the same thing that stands between the thoughts (...) and terms themselves).

Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

Ontological pluralism is the view that there are different fundamental ways of being. Trenton Merricks has recently raised three objections to combining pluralism with a generic way of being enjoyed by absolutely everything there is: first, that the resulting view contradicts the pluralist’s core intuition; second, that it is especially vulnerable to the charge—due to Peter van Inwagen—that it posits a difference in being where there is simply a difference in kind; and, third, that it is in tension with various (...) historically influential motivations for pluralism. I reply to each of these objections in turn. My replies will help to bring out the true nature of the pluralist’s basic commitments. (shrink)

Quine’s argument for a naturalized epistemology is routinely perceived as an argument from despair: traditional epistemology must be abandoned because all attempts to deduce our scientific theories from sense experience have failed. In this paper, I will show that this picture is historically inaccurate and that Quine’s argument against first philosophy is considerably stronger and subtler than the standard conception suggests. For Quine, the first philosopher’s quest for foundations is inherently incoherent; the very idea of a self-sufficient sense datum language (...) is a mistake as there is no science-independent perspective from which to validate science. I will argue that a great deal of the confusion surrounding Quine’s argument is prompted by certain phrases in his seminal ‘Epistemology Naturalized’. Scrutinizing Quine’s work both before and after the latter paper provides a better key to understanding his remarkable views about the epistemological relation between theory and evidence. -/- .

The informal logic movement began as an attempt to develop – and teach – an alternative logic which can account for the real life arguing that surrounds us in our daily lives – in newspapers and the popular media, political and social commentary, advertising, and interpersonal exchange. The movement was rooted in research and discussion in Canada and especially at the University of Windsor, and has become a branch of argumentation theory which intersects with related traditions and approaches (notably formal (...) logic, rhetoric and dialectics in the form of pragma-dialectics). In this volume, some of the best known contributors to the movement discuss their views and the reasoning and argument which is informal logic’s subject matter. Many themes and issues are explored in a way that will fuel the continued evolution of the field. Federico Puppo adds an insightful essay which considers the origins and development of informal logic and whether informal logicians are properly described as a “school” of thought. In considering that proposition, Puppo introduces readers to a diverse range of essays, some of them previously published, others written specifically for this volume. (shrink)

Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...) this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

What are words? What makes two token words tokens of the same word-type? Are words abstract entities, or are they (merely) collections of tokens?

Moral metasemantic theories explain how our moral thought and talk are about certain properties. Given the connection between what our moral terms are about and which moral claims are true, it might be thought that metasemantic theorising can justify first-order ethical conclusions, thus providing a novel way of doing moral epistemology. In this paper, we spell out one kind of argument from metasemantic theories to normative ethical conclusions, and argue that it fails to transmit justification from premises to conclusion. We (...) give three reasons for this transmission failure, which together pose a serious challenge to such metasemantic arguments. (shrink)

On the traditional approach to metaethics, theories are expected to be faithful to ordinary normative discourse – or at worst (if we think the ordinary discourse is metaphysically unsound) to deviate from it as little as possible. -/- This paper develops an alternative, “conceptual engineering” approach to metaethical enquiry, which is not in this way restricted by our present discourse. On this approach, we will seek to understand the psychology, semantics, metaphysics and epistemology, not just of our present concepts, but (...) also of other possible normative concepts. The ultimate point of the enquiry is to choose between the available alternatives: to decide what kinds of normative concepts to use, going forward. -/- The paper aims to make this suggestion precise, in a way that a) answers worries about circularity, b) answers worries about “changing the subject”, c) retains metaethics as a truth-seeking enquiry, and d) leads to an independently plausible methodology.

Attitude verbs like ‘believe’ and ‘want’ exhibit neg-raising: an ascription of the form a doesn’t believe that p tends to convey that a disbelieves—i.e., believes the negation of—p. In ‘Belief is Weak’, Hawthore et al. observe that neg-raising does not occur with verbs like ‘know’ or ‘need’. According to them, an ascription of the form a believes that p is true just in case a is in a belief state that makes p more likely than not, and so—excepting cases of (...) complete indifference—a will either believe p or disbelieve p. I expand and revise this explanation: so-called ‘weak’ attitude verbs are used in ascriptions of an opinion about some subject matter S—a kind of selection from among the elements of S—and these ascriptions are themselves responsive to conversational topics that presuppose that the subject of the ascription has an opinion about S. ‘Strong’ attitude verbs denote more direct relationships between subject and world.

McTaggart’s paradox and his A-theory and B-theory are basic notions in the contemporary philosophy of time. It is well known that the paradox was introduced by McTaggart’s paper called “The Unreality of Time” published in 1908, so that it has a one-hundred-year history. As for A-theory and B-theory, in contrast, McTaggart himself didn’t consider both of them at all. The notions of A-theory and B-theory came much later, 60 years after the paradox. Moreover, they had not been as popularized as (...) they are today until quite recently, at least after the 1990s. This paper aims to trace the origin of the notions of A-theory and B-theory and show how the debates behind them, especially objections to “spatialising time,” form the notions. (shrink)

This paper argues that functionalist metasemantic views, such as Conceptual Role Semantics and Interpretivism, face a Euthyphro challenge. The challenge, put roughly, is this: functionalist metasemantic views reverse the order of explanation. According to such views, representational mental states have the contents that they do partly because they play certain roles in our mental lives. According to an intuitive picture of the roles that representational mental states play in our mental lives, however, these states play the roles they do partly (...) because they have the contents that they do. Since explanations—even partial ones—are asymmetric (call this principle ‘the Euthyphro Principle’), we can’t accept both this intuitive picture and a functionalist metasemantics. Hence, we should reject all versions of the latter. This paper can be seen as an attempt to better articulate an intuition that has been suggested in various forms in the literature. The paper proceeds as follows. First, it shows that functionalist metasemantic views imply certain ‘partly because’ claims. Second, it argues for the Euthyphro Principle. Third, it defends the intuitive picture of representational mental states and shows that it implies ‘partly because’ claims that conflict with those made by functionalist metasemantic views. Finally, it considers ways of relaxing the intuitive picture and finds them all wanting. (shrink)

In this paper, I examine Quine's views on the epistemology of logic. According to Quine's influential holistic account, logic is central in the “web of belief” that comprises our overall theory of the world. Because of this, revisions to logic would have devastating systematic consequences, and this explains why we are loath to make such revisions. In section1, I clarify this idea and thereby show that Quine actually takes the web of belief to have asymmetrical internal structure. This raises two (...) puzzles. First, as I show in section 2, Quine's mature thoroughly naturalized view has it that logic is simply obvious, and this is explains why we do not typically consider revising it. While Quine presents this naturalized view as a way to make good on his earlier metaphor of centrality in a web of belief, I argue that the resources of Quine's naturalized epistemology cannot adequately explain why we are reluctant to revise logic. And, Quine seems to recognize this point himself. In light of this, I explain in section 3 how Quine can allow that our overall scientific theory has systematic structure in a way that is consistent with his naturalistic strictures. Second, the asymmetrical internal structure of the web of belief seems to be inconsistent with its being a holistic web at all. I defuse this problem in section 4 by showing how Quine distinguishes between structural and confirmational considerations. I close by using this distinction to show how Quine's view can evade Michael Friedman’s criticisms, and allow for important methodological distinctions between areas of the web of belief. (shrink)
