Much recent discussion in the philosophy of mathematics has concerned the indispensability argument—an argument which aims to establish the existence of abstract mathematical objects through appealing to the role that mathematics plays in empirical science. The indispensability argument is standardly attributed to W. V. Quine and Hilary Putnam. In this paper, I show that this attribution is mistaken. Quine's argument for the existence of abstract mathematical objects differs from the argument which many philosophers of mathematics ascribe to him. Contrary to (...) appearances, Putnam did not argue for the existence of abstract mathematical objects at all. I close by suggesting that attention to Quine and Putnam's writings reveals some neglected arguments for platonism which may be superior to the indispensability argument. (shrink)

There has been a resurgence of interest lately within philosophy of mind and action in the category of mental action. Against this background, the present paper aims to question the very possibility, or at least the theoretical significance, of teasing apart mental and bodily acts. After raising some doubts over the viability of various possible ways of drawing the mental act/bodily act distinction, the paper draws some lessons from debates over embodied cognition, which arguably further undermine the credibility of the (...) distinction. The insignificance of the distinction is demonstrated in part by showing how the focus on ‘inner’ acts hampers fruitful discussion of Galen Strawson’s skepticism of mental agency. Finally, the possibility is discussed that a distinction between covert and overt action should supplant the one between mental and bodily action. (shrink)

Intention Cognitivism – the doctrine that intending to V entails, or even consists in, believing that one will V – is an important position with potentially wide-ranging implications, such as a revisionary understanding of practical reason, and a vindicating explanation of 'Practical Knowledge'. In this paper, I critically examine the standard arguments adduced in support of IC, including arguments from the parity of expression of intention and belief; from the ability to plan around one's intention; and from the explanation provided (...) by the thesis for our knowledge of our intentional acts. I conclude that none of these arguments are compelling, and therefore that no good reason has been given to accept IC. (shrink)

I clarify in what sense one might want to claim that thought or language are public. I distinguish among four forms that each of these claims might take, and two general ways of establishing them that might be contemplated. The first infers the public character of thought from the public character of language, and the second infers the latter from the former. I show that neither of these stategies seems to be able to dispense with the claim that thought and (...) language are interdependent, and that the second strategy raises more difficulties than the first. I then examine the reasoning by which Davidson means to establish that thought depends on language. I claim that this reasoning is not conclusive, and that it can be adapted in such a way as to establish a version of the thesis that thought is public which does not presuppose that language is public, and a version of the thesis that language is public which does not imply that thought depends on language. I conclude with the suggestion that despite appearances to the contrary Davidson's doctrine is defensible only if it implies at least the conceivability of intentional systems that would lack language altogether.

In this article we aim to reconstruct some aspects of Davidson's idea of triangulation, and against this reconstruction, ask whether the idea is viciously circular. We begin by looking at the claim that without a triangularn setting, there is no saying what the cause of a being's responses is. In the first section we discuss the notion of relevant similarity, and what difference the presence of a second non‐linguistic being could make for the individuation of a common focus of attention. (...) In the second section we look at the role of a second person in language‐acquisition. It is important that being corrected to ‘go on as others do’ does not yet presuppose thought, and similarity standards can be applied to a learner's reactions even before she is aware of these standards. We also show why Davidson is not committed to any consensus view of correctness. In the last section we discern three charges of circularity that can be levelled against the idea of triangulation. We argue that Davidson can respond to the first two charges, and point to a way of answering the third. But the response we propound raises a new question, namely, why does the second being have to be a speaker or thinker even before the learner is aware of the three points of the triangle? (shrink)

This essay discusses Kant and Hegel’s philosophies of action and the place of action within the general structure of their practical philosophy. We begin by briefly noting a few things that both unite and distinguish the two philosophers. In the sections that follow, we consider these and their corollaries in more detail. In so doing, we map their differences against those suggested by more standard readings that treat their accounts of action as less central to their practical philosophy. Section 2 (...) discusses some central Kantian concepts. In Section 3, we take a closer look at the distinction between internal and external action, as found in Kant’s philosophy of morality and legality. In Section 4, we turn to Hegel and his distinctions between abstract right, morality, and ethical life, as well as the location of his account of action within his overall theory of morality. We discuss the distinction between Handlung and Tat, and non-imputable consequences. The overall aims of our essay are to shed light on some puzzles in Kant and Hegel’s conceptions and to examine where their exact disputes lie without taking a stand on which philosophy is ultimately the most satisfactory.

The main purpose of the paper concerns the question of the existence of hard mathematical facts as truth-makers of mathematical sentences. The paper defends the standpoint according to which hard mathematical facts do not exist in semantic models of mathematical theories. The argumentative line in favour of the defended thesis proceeds as follows: slingshot arguments supply us with some reasons to reject various ontological theories of mathematical facts; there are two ways of blocking these arguments: through the rejection of the (...) principle of extensionality for individual terms or through the rejection of the principle of Wittgenstein; the first way cannot be accepted because it leads to the practice of softening mathematical facts; the second way, called fine-graining facts, cannot be accepted because it also results in the practice of softening facts. Hence, only soft mathematical facts can be introduced into semantic models of mathematical theories. Because they should be rather interpreted as mental representations of mathematical objects, they no longer satisfy the semantic role of truth-makers in relation to mathematical sentences. The argument formulated in the paper is based on the analysis of mathematical extensions of the basic non-Fregean logic. Sixty-two definitions of potential fact-identity connectives are also presented. The paper's conclusion may be interpreted as undermining the situational paradigm of building semantics for mathematical languages. (shrink)

Despite the renown of ‘On Denoting’, much criticism has ignored or misconstrued Russell's treatment of scope, particularly in intensional, but also in extensional contexts. This has been rectified by more recent commentators, yet it remains largely unnoticed that the examples Russell gives of scope distinctions are questionable or inconsistent with his own philosophy. Nevertheless, Russell is right: scope does matter in intensional contexts. In Principia Mathematica, Russell proves a metatheorem to the effect that the scope of a single occurrence of (...) a description in an extensional context does not matter, provided existence and uniqueness conditions are satisfied. But attempts to eliminate descriptions in more complicated cases may produce an analysis with more occurrences of descriptions than featured in the analysand. Taking alternation and negation to be primitive (as in the first edition of Principia), this can be resolved, although the proof is non-trivial. Taking the Sheffer stroke to be primitive (as proposed by Russell in the second edition), with bad choices of scope the analysis fails to terminate. (shrink)

In this paper I propose a novel treatment of generic sentences, which proceeds by means of different levels of analysis. According to this account, all generic sentences (I-generics and D-generics alike) are initially treated in a uniform manner, as involving higher-order predication (following the work of George Boolos, James Higginbotham and Barry Schein on plurals). Their non-uniform character, however, re-emerges at subsequent levels of analysis, when the higher-order predications of the first level are cashed out in terms of quantification over (...) individuals: this last step, I suggest, involves knowledge concerning the lexical meaning of the predicates in question.

Niko Kolodny It is often said that there is a special class of norms, ‘rational requirements’, that demand that our attitudes be related one another in certain ways, whatever else may be the case.1 In recent work, a special class of these rational requirements has attracted particular attention: what I will call ‘requirements of formal coherence as such’, which require just that our attitudes be formally coherent.2 For example, we are rationally required, if we believe something, to believe what it (...) entails. And we are rationally required, if we intend an end, to intend what we take to be necessary means to it. The intuitive idea is that formally incoherent attitudes give rise to a certain normative tension, or exert a kind of rational pressure on each another, and this tension, or pressure, is relieved just when one of the attitudes is revised. As John Broome observes, these requirements are, by their nature, ‘wide scope’, which is to say that there is no particular attitude that one must have or lack in order to satisfy them. This is because they require just formal coherence, and there is no particular attitude that one must have or lack in order to be formally coherent. (shrink)

In this paper, I seek to refute arguments for the idea that folk psychological explanation, i.e., the explanation of actions, beliefs and desires in terms of one another, should be understood as being of a different character than ordinary scientific explanations, a view defended most prominently in analytical philosophy by Donald Davidson and John McDowell. My strategy involves arguing both against the extant arguments for the idea that FP must be construed as giving such explanations, and also against the very (...) notion of such a different kind of explanation. I argue first that the in some sense a priori and conceptual nature of folk psychological principles does not support the idea that these are other than empirical generalisations, by appeal to recent nativist ideas in cognitive science and to Lewis's conception of the meaning of theoretical terms. Second, I argue that there is no coherent sense in which folk psychological explanations can be seen as normative. Thirdly, I examine the putatively holistic character of the mental and conclude that that too fails to provide any cogent reasons for viewing folk psychological explanations as different from other kinds of explanation.

Much of the modern philosophy of causation has been governed by two ideas: (i) causes make their effects inevitable; (ii) a cause is something that makes a difference to whether its effect occurs. I focus on explaining the origin of idea (ii) and its connection to (i). On my view, the frequent attempts to turn (ii) into an analysis of causation are wrongheaded. Patterns of difference-making aren't what makes causal claims true. They merely provide a useful test for causal claims. (...) Moreover, what justifies us in using them as a test is idea (i). That's how (i) and (ii) are connected. (shrink)

This paper offers an analysis of indexical expressions and proper names as they are used in proverbs. Both indexicals and proper names contribute properties rather than objects to the propositions expressed when they are used in sentences interpreted as proverbs. According to the proposal, their contribution is accounted for by the mechanism of descriptive anaphora. Indexicals with rich linguistic meaning, such as ‘I’, ‘you’ or ‘today’, turn out to be cases of the attributive uses of indexicals, i.e. uses whose contribution (...) relies on the linguistic meaning of the word. Third person pronouns, names of locations as well as surnames are analyzed as non-attributive descriptive uses. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

La philosophie analytique de l'action se réclame du langage ordinaire de l'action comme une des sources de ses data philosophiques. Elle se propose d'en examiner le fonctionnement, d'en extraire les concepts clés, de caractériser les formes de propositions dans lesquelles s'expriment nos actions et notre façon spontanée de les comprendre, d'examiner l'articulation propre aux stratégies d'action et au discours qui les justifie, et de faire des « proposals » pour la construction d'une théorie de l'action. En somme, il s'agit d'ériger (...) le langage ordinaire en instance de contrôle aussi bien sur le plan du traitement de problèmes philosophiques que sur celui de la construction de méta-théories des sciences de l'homme. Ce travail sur le langage de l'action peut revêtir plusieurs fonctions: fonction de clarification ou de détection de confusions, fonction thérapeutique pour guérir le langage de maladies philosophiques, c'est-à-dire des pseudo-problèmes, fonction heuristique pour prescrire une diète appropriée au traitement des perplexités philosophiques qui surgissent « quand le langage tourne à vide, non quand il travaille », pour employer le mot de Wittgenstein.

La théorie du choix social qui s'est développée durant les dernières décennies, notamment dans la ligne des travaux d'Arrow et de Sen , ne s'est pas seulement soldée par une série de résultats négatifs exprimés dans les théorèmes d'impossibilité d'Arrow, de Sen et d'autres; ses notions centrales ont aussi été utilisées de manière fort variée au point que cette théorie souffre aujourd'hui d'un déficit important qui se traduit par de multiples indéterminations conceptuelles.

Les représentants de l'École autrichienne sont ici mis sous la même bannière pour autant seulement qu'ils ont été unanimes à revendiquer pour les postulats de l'économie pure, les «lois exactes» de la théorie économique, c'est-à-dire de la théorie marginale de l'utilité, un statut particulier en ce sens qu'ils tenaient pour impossible, voire absurde ou simplement inutile de soumettre les postulats en cause à des tests empiriques. L'apriorisme dont ils se réclament, fait à juste titre la marque de commerce de l'École (...) marginaliste autrichienne; Menger en a fourni les principes, von Mises la justification, et Rothbard s'est occupé de propager la doctrine de l'autre côté de l'Atlantique.

Some theories of linguistic meaning, such as those of Paul Grice and David Lewis, make appeal to higher–order thoughts: thoughts about thoughts. Because of this, such theories run the risk of being empirically refuted by the existence of speakers who lack, completely or to a high degree, the capacity of thinking about thoughts. Research on autism during the past 15 years provides strong evidence for the existence of such speakers. Some persons with autism have linguistic abilities that qualify them as (...) speakers, but manifest a severely impaired capacity to understand what it is to have beliefs. (shrink)

The exploration of the mechanisms of cultural heredity has often been regarded as the key to explicating human uniqueness. Particularly early imitative learning, which is explained as a kind of simulation that rests on the infant’s identification with other persons as intentional agents, has been stressed as the foundation of cumulative cultural transmission. But the question of what are the objects of this mechanism has not been given much attention. Although this is a pivotal point, it still remains obscure. I (...) will characterize the notion of action-types and show why they are the genuine objects of cultural heredity. However, this answer is in conflict with the concept of imitation, and the problem arises that, if imitation is conceptualized as simulation and explained in terms of the cognition of infants, the objects of cultural transmission seemingly cannot be passed on by imitation. In order to solve this problem, I propose reconsidering the concept of imitation and to conceptualize imitation as a cooperative activity of infants and adults. (shrink)

In this article I discuss and evaluate the selectivity problem as a problem put forward by Bermudez (1997, 2000) against anti-intentionalist accounts of self-deception. I argue that the selectivity problem can be raised even against intentionalist accounts, which reveals the too demanding constraint that the problem puts on the adequacy of a psychological explanation of action. Finally I try to accommodate the intuitions that support the cogency of the selectivity problem using the resources from the framework provided by an anti-intentionalist (...) account of self-deception.

The issue whether psychopathic offenders are practically rational has attracted philosophical attention. The problem is relevant in theoretical discussions on moral psychology and in those concerning the appropriate social response to the crimes of these individuals. We argue that classical and current experiments concerning the instrumental learning in psychopaths cannot directly support the conclusion that they have impaired instrumental rationality, construed as the ability for transferring the motivation by means-ends reasoning. In fact, we defend the different claim that these experiments (...) appear to show that psychopaths in certain circumstances are not aware of the relevant means for their ends. Moreover, we suggest how further empirical research could help to settle the issue. (shrink)

In this paper I propose and defend an account of color that I call color functionalism. I argue that functionalism is a non-traditional species of primary quality theory, and that it accommodates our intuitions about color and the facts of color science better than more widely discussed alternatives.

This paper is concerned with the problem of selfidentification in the domain of action. We claim that this problem can arise not just for the self as object, but also for the self as subject in the ascription of agency. We discuss and evaluate some proposals concerning the mechanisms involved in selfidentification and in agencyascription, and their possible impairments in pathological cases. We argue in favor of a simulation hypothesis that claims that actions, whether overt or covert, are centrally simulated (...) by the neural network, and that this simulation provides the basis for action recognition and attribution.

Stephen Barker presents a novel approach to solving semantic paradoxes, including the Liar and its variants and Curry’s paradox. His approach is based around the concept of alethic undecidability. His approach, if successful, renders futile all attempts to assign semantic properties to the paradoxical sentences, whilst leaving classical logic fully intact. And, according to Barker, even the T-scheme remains valid, for validity is not undermined by undecidable instances. Barker’s approach is innovative and worthy of further consideration, particularly by those of (...) us who aim to find a solution without logical revisionism. As it stands, however, the approach is unsuccessful, as I shall demonstrate below. (shrink)

Akeel Bilgrami has always argued that the contents of our thoughts are constitutively constrained by what we could be said to know about them. In earlier work he explained this in terms of a connection between thought and rationality, but his recent book argues that the ultimate ground for self-knowledge rests in our notion of responsibility. This paper will examine these arguments, and suggest that if Bilgrami is right about how self-knowledge is grounded, then it need not constrain our content (...) ascriptions as thoroughly as he once proposed that it must.

The view (held, e.g., by Davidson) that the having of beliefs and desires presupposes the having of reflective capacities is sometimes supported by appealing to the idea that the concept of belief is a concept of a mental state which involves a normative aspect: beliefs can be “successful” or “unsuccessful” from the perspective of their possessors, and sometimes discarded in light of their “failure.” This naturally invites the idea that believers must be capable of reflecting on their beliefs. Desires presuppose (...) reflectivity if only in virtue of their essential linkage with beliefs. This paper suggests a sense in which mental states—including those of non-reflective creatures—can have such a normative aspect. On this suggestion, the intelligible relations that obtain between cognitive states and conative states open the door for the possibility of normativity without reflectivity. Due to these relations, a creature's beliefs can be successful or unsuccessful from its own perspective even without its conceiving of them. (shrink)

An important argument for the belief-desire thesis is based on the idea that an agent can be motivated to act only if her mental states include one which aims at changing the world, that is, one with a “world-to-mind”, or “telic”, direction of fit. Some cognitivists accept this claim, but argue that some beliefs, notably moral ones, have not only a “mind-to-world”, or “thetic”, direction of fit, but also a telic one. The paper first argues that this cognitivist reply is (...) deficient, for only the “dominant” direction of fit of an attitude is responsible for its character and function. Further, it seems that the dominant direction of fit of an attitude is determined by its psychological mode, and so all beliefs seem to have a dominant thetic direction of fit, and to be motivationally inert. The main part of this paper, however, is devoted to explaining how it is that attitudes, like moral attitudes, can truly have two directions of fit in a way which enables them to be both cognitive and motivational. Reflection on the nature of beliefs suggests that the claim that the dominant direction of fit of an attitude is determined by its psychological mode should be qualified. The reasons beliefs provide draw their authority for the agent – their demanding nature – from the objects represented by these beliefs, and so, it is the beliefs’ content which determine their dominant direction of fit, as far as their role in practical reasoning is concerned. Thus, in the sense relevant to practical reasoning a belief with a normative content does have a dominant telic direction of fit. At the same time, in the sense relevant to its satisfaction conditions a moral belief has a dominant thetic direction of fit, which underlies its classification as a cognitive attitude. Cognitivists, then, can have it both ways. (shrink)

The term ‘logical form’ has been called on to serve a wide range of purposes in philosophy, and it would be too ambitious to try to survey all of them in a single essay. Instead, I will focus on just one conception of logical form that has occupied a central place in the philosophy of language, and in particular in the philosophical study of linguistic meaning. This is what I will call the classical conception of logical form. The classical conception, (...) as I will present it in section 1, has (either explicitly or implicitly) shaped a great deal of important philosophical work in semantic theory. But it has come under fire in recent decades, and in sections 2 and 3 I will discuss two of the recent challenges that I take to be most interesting and significant. (shrink)

Most ?theories of consciousness? are based on vague speculations about the properties of conscious experience. We aim to provide a more solid basis for a science of consciousness. We argue that a theory of consciousness should provide an account of the very processes that allow us to acquire and use information about our own mental states ? the processes underlying introspection. This can be achieved through the construction of information processing models that can account for ?Type-C? processes. Type-C processes can (...) be specified experimentally by identifying paradigms in which awareness of the stimulus is necessary for an intentional action. The Shallice (1988b) framework is put forward as providing an initial account of Type-C processes, which can relate perceptual consciousness to consciously performed actions. Further, we suggest that this framework may be refined through the investigation of the functions of prefrontal cortex. The formulation of our approach requires us to consider fundamental conceptual and methodological issues associated with consciousness. The most significant of these issues concerns the scientific use of introspective evidence. We outline and justify a conservative methodological approach to the use of introspective evidence, with attention to the difficulties historically associated with its use in psychology. (shrink)
