I examine an argument proposed by Tye and Wright, inspired by Geach, which holds that a correct understanding of how conceptual thought occurs in time demands we expel it from experience. This would imply—pace William James— that the “stream of consciousness” is not, even in part, a “stream of thought.” I argue that if we closely examine what seems to support crucial premises of their argument, we will find this undermines its other assumptions, and points us to a way of (...) placing thought in time that they neglect. Ultimately, attention to the phenomenology of language comprehension and production not only undercuts their “temporality argument” against including thought in experience; it prepares the ground for a case in favor of inclusion. In critiquing their argument I hope not just to disarm an objection to a view I espouse, nor even just to discover new support for it, but also to shed some light on the temporality of thought and its relation to self-expression.

In this article I first analyze the meaning of mixed feelings and what this expression refers to. I argue that what the term mixed feelings is commonly taken to mean are not mixed feelings because there is no mixture, and also because the same object and the same time condition of what is supposed to be mixed is not satisfied. I then pass on to a case of genuine mixed feelings. Genuinely mixed feelings are feelings composed of simple or basic (...) feelings as well as occurrences of compounds and sets of feelings. I then discuss three categories adjacent to mixed feelings: layered feelings, metaemotions, and moods. Layered feelings are not mixed but superposed one over another, metaemotions have a mixed phenomenology, and moods are an affective mixture par excellence. In conclusion, I suggest that wrong labelling coincides with a category mistake which hampers further progress in the philosophy of affectivity. (shrink)

Many hold that theoretical reasoning aims at truth. In this paper, I ask what it is for reasoning to be thus aim-directed. Standard answers to this question explain reasoning’s aim-directedness in terms of intentions, dispositions, or rule-following. I argue that, while these views contain important insights, they are not satisfactory. As an alternative, I introduce and defend a novel account: reasoning aims at truth in virtue of being the exercise of a distinctive kind of cognitive power, one that, unlike ordinary (...) dispositions, is capable of fully explaining its own exercises. I argue that this account is able to avoid the difficulties plaguing standard accounts of the relevant sort of mental teleology. (shrink)

Self-consciousness can be understood as the ability to think I-thou-ghts which can be described as thoughts about oneself ‘as oneself’. Self-consciousness possesses two specific correlated features: the first regards the fact that it is grounded on a first-person perspective, whereas the second concerns the fact that it should be considered a consciousness of the self as subject rather than a consciousness of the self as object. The aim of this paper is to analyse a few considerations about Descartes and Hume’s (...) approaches to self-consciousness, as both philosophers introduce a first-personal method of accessing the subjective dimension through an introspective account. Descartes’s view on self-consciousness seems incapable of conceiving and recognizing herself as herself, while Hume’s seems to lack those features assigned to the consciousness of self-as-subject.

I present a paradoxical combination of desires. I show why it's paradoxical, and consider ways of responding. The paradox saddles us with an unappealing trilemma: either we reject the possibility of the case by placing surprising restrictions on what we can desire, or we deny plausibly constitutive principles linking desires to the conditions under which they are satisfied, or we revise some bit of classical logic. I argue that denying the possibility of the case is unmotivated on any reasonable way (...) of thinking about mental content, and rejecting those desire-satisfaction principles leads to revenge paradoxes. So the best response is a non-classical one, according to which certain desires are neither determinately satisfied nor determinately not satisfied. Thus, theorizing about paradoxical propositional attitudes helps constrain the space of possibilities for adequate solutions to semantic paradoxes more generally. (shrink)

I introduce a perceptual phenomenon so far overlooked in the philosophical literature: ‘visual evanescence’. ‘Evanescent’ objects are those that due to their structured visible appearances have a tendency to vanish or evanesce from sight at certain places and for certain ‘biologically apt’ perceivers. Paradigmatically evanescent objects are those associated with certain forms of animal camouflage. I show that reflection on visual evanescence helps create conceptual room for a treatment of looks statements not explicit in the contemporary literature, one which takes (...) its cue from the relatively neglected philosophy of perception of G.E.M. Anscombe. In sensory contexts in which evanescence is known to have occurred, the use of ‘looks invisible’ seems to be intelligible, a fact that sensationalist and objectivist treatments of the nature of looks, as I call them, cannot obviously accommodate - at least, as I explain, when coupled with what Cora Diamond (1981) describes as a ‘natural’ understanding of nonsense. Focusing on a number of imaginative scenarios in which the statement ‘looks invisible’ is permissible, I oppose these ontological treatments with the grammatical approach I draw from Anscombe and in doing so I uncover a degree of unity across the cases I consider: something can intelligibly be said to ‘look invisible’ if one can see or appears to see the entirety of the region that the ‘invisible’ thing occupies. The region ‘looks empty’ but is full. (shrink)

This thesis is about experiential content: what it is; what kind of account can be given of it. I am concerned with identifying and attacking one main view - I call it the inferentialist proposal. This account is central to the philosophy of mind, epistemology and philosophy of science and perception. I claim, however, that it needs to be recast into something far more subtle and enriched, and I attempt to provide a better alternative in these pages. The inferentialist proposal (...) holds that experiential content is necessarily under¬pinned by sophisticated cognitive influences. My alternative, the continuum theory, holds that these influences are relevant to experience only at certain levels of organisation and that at other levels there are contents which such features do not capture at all. Central to my account is that there are degrees to which cognitive influences affect experiential content; indeed, for the most part, experience is an amalgam of both inferential and non-inferential features. I claim that the inferentialist proposal is fundamentally flawed and deserves replacement, and I argue that my alternative fills the hollow that remains. The thesis is divided into four sections. In Part I, Chapter 1, I introduce two traditionally rival views of experiential content. In Chapter 2, I develop my continuum alternative. Chapter 3 assesses the relationship between experience and language, while Chapter 4 explores the relationship between beliefs and experience. The overall argument is that it has been a mistake to understand experience simply in inferential or non-inferential terms. In Part II, I examine the structure of mental content. Chapter 5 is concerned with the kinds of experiences which escape the inferentialist analysis. Chapter 6 considers Kant’s metaphysic of experience counterpointed to Lorenz’s reading of his work in the light of evolutionary biology. Chapter 7 treats animal experience in relation to the continuum view I am developing, while Chapter 8 reviews Fodor’s contribution to perceptual psychology. It is argued that the view of experiential content being developed is both consistent with empirical data on informationally local perceptual sub-systems, but also accords well with evolutionary theory and a naturalist interpretation of Kant’s taxonomy. Part III deals with inferentialism in the philosophy of science. In Chapter 9, I assess the theory dependence of observation thesis as it is advanced by Paul Feyerabend. I bring out of his account a subtle confusion concerning the importance of inference in the context of scientific inquiry. Part IV deals with the issue of experience in the philosophy of mind. In Chapter 10, I look at Wilfred Sellars’s attack on sense data theories. Chapter 11 confronts Paul Churchland’s treatment of ‘folk psychology’ while Chapter 12 isolates the issue of experiential qualia and the position of property dualism. I offer a critical review of Thomas Nagel’s work in this chapter and claim that his position can be read in a way which is consistent with the continuum account I am developing. I conclude the thesis in the usual fashion with a summary of the central claims. (shrink)

Philosophy and Literature is an internationally renowned refereed journal founded by Denis Dutton at the University of Canterbury, Christchurch. It is now published by the Johns Hopkins University Press. Since its inception in 1976, Philosophy and Literature has been concerned with the relation between literary and philosophical studies, publishing articles on the philosophical interpretation of literature as well as the literary treatment of philosophy. Philosophy and Literature has sometimes been regarded as iconoclastic, in the sense that it repudiates academic pretensions, (...) insidious jargon and institutional vogue. Dutton, who remains the editor, still writes a regular column. A distinctive feature of Philosophy and Literature was the annual Bad Writing Contest, held from 1995–98, which sought to identify (and publish) the ‘most stylistically lamentable passages’ of academic prose, often to great amusement.

The paper presents a new theory of perceptual demonstrative thought, the property-dependent theory. It argues that the theory is superior to both the object-dependent theory (Evans, McDowell) and the object-independent theory (Burge).

I shall first set out the main lines of Meinong’s account then look at the theo- ries of dependence and possibility on which it is based. Finally I consider some applications of the theory, most of which are at least hinted at by Meinong.

What is the relationship between unconscious and conscious intentionality? Contemporary philosophy of mind treats the contents of conscious 10 intentional mental states as the same kind of thing as the contents of un- conscious mental states. According to the standard view that beliefs and desires are propositional attitudes, for example, the contents of these states are propositions, whether or not the states are conscious or unconscious. I dispute this way of thinking of conscious and unconscious content, and propose an alternative, (...) which helps to explain why the various mental things that are called unconscious deserve that label.

I IntroductionAtMetaphysicsΓ 3, Aristotle argues that it belongs to a single discipline, which he callsfirst philosophy,to investigate both substance and a special class of claims which includes among its members the principle of non-contradiction. At Γ 4, after insisting that the PNC is, strictly speaking, indemonstrable, he sets forth a series of sketches of refutative arguments intended to show how it can, nonetheless, be substantiated. Traditionally, his main refutative argument has been taken to be embedded in the passage which runs (...) from 1006a31 tob34. In that passage, he tries to show that anyone who denies the PNC and who can then be led, by means of an artfully arranged series of questions, to agree to a few seemingly modest theses about the signification of expressions of a certain type — which Aristotle illustrates with the general term ‘man’ — is thereby logically committed to the following modal claim: ‘It is necessary, then, if it is true to say that something is a man, that it be a bipedal animal'.

According to neo-Russellianism, in a sentence such as John believes that Mont Blanc is 4000 m high, any other proper name co-referring with Mont Blanc can be substituted for it without any change in the proposition expressed. Prima facie, our practice of translation shows that this cannot be correct. We will then show that neo-Russellians have a way out of this problem, which consists in holding that actual translations are not a matter of semantics, but also make an attempt at (...) preserving some pragmatic features of the sentences to be translated. We then turn to translations that only preserve the semantic characteristics of the sentences and we argue that, although these translations are unable to show that neo-Russellianism is incorrect, they still show that it relies on some theses that seem to have no justification, apart from saving neo-Russellianism itself.

I believe that there are only a select few topics, which arouse a similar level of interest and curiosity among academics and laymen alike, as does the study of mind and brain. Although mind and brain have been capturing the attention of philosophers for centuries, it is the "scientific investigation" of age old philosophical queries by socalled cognitive scientists, which is distinctive of the developments of the last few decades and which, in times to come, may well be considered the (...) hallmark of the study of mind in the 20th and early 21st centuries. In the past, advances in the natural sciences underlay or boosted a plethora of developments in the technological, economic and political spheres that not only improved the standard of living and prolonged the average life span for a vast number of people, but also fuelled hopes that a new and improved understanding of the nature of man was also within reach. Despite all the benefits mankind derived from scientific and technological progress past and present, the success of the natural sciences also helped spread and foster a virulent and nowadays quasi-ubiquitous and unquestioned believe in the omnipotence of science and technology. In the context of the study of mind, in particular, it fostered the widespread conception that in order for an investigation leading to insight and understanding a "scientific" approach is a sine qua non. This thesis highlights the danger of such an approach. By investigating the framework of explanation adopted by cognitive scientists, the cognitive view, and by examining its inherent conceptions of mind and thought, it will be shown that the scientific, or rather scientistic, approach inherent in the views depicted above is highly questionable, and in the case of the study of mind and brain, does not further insight and understanding, but rather prevents it. In the 20th century, Ludwig Wittgenstein has been one of the few philosophers who recognized the fallaciousness of these ideas and who opposed the inherent scientism. His later philosophy, which provides the philosophical mise en scène for the following investigations, provides a much-needed antidote against the misconceptions common among cognitive scientists today. Although, many of the shortcomings of the ideas and views of cognitive scientists have, with a certain regularity, been discussed by philosophers working in the tradition of the later Wittgenstein their criticisms, more often than not, fell on deaf ears. I believe that one of the main reasons underlying the imperviousness of the community of cognitive scientists to the criticism of the kind of analytic philosophy inspired by the later Wittgenstein, is that it mainly focused on select misconceptions inherent in the cognitive view, but regularly failed to point out their place in the overall framework of thought for cognitive scientists. As a result, it was easy to dismiss these criticisms with excuses of the sort "but that does not bear any direct relevance to the work I do...". For this reason, this thesis aimed to portray and examine the cognitive view in its entirety, i.e. to depict the intricate interconnections existing between the premises that provide the foundation of the cognitive view, and to point out their disastrous consequences for our understanding not only of a select view aspects of mental phenomena, but to our understanding of the mind in its entirety. In order to provide such a "big picture", and to describe the numerous often very subtle interconnections between the various ideas making up the cognitive view in all their breadth and depth, a lot of well-trodden ground had to be revisited and reviewed. Thus, Anthony Kenny's and Peter Hackers' discussions of the mereological fallacy will provide the "base camp" from which we will visit less familiar aspects of the cognitive view via novel routes on our way to the peak of this "philosophical mountain". Where required, my indebtedness to the works of these philosophers will be highlighted throughout the text. (shrink)

This paper brings together several strands of thought from both the analytic and phenomenological traditions in order to critically examine accounts of cognitive enhancement that rely on the idea of cognitive extension. First, I explain the idea of cognitive extension, the metaphysics of mind on which it depends, and how it has figured in recent discussions of cognitive enhancement. Then, I develop ideas from Husserl that emphasize the agential character of thought and the distinctive way that conscious thoughts are related (...) to one another. I argue that these considerations are necessary for understanding why forms of cognitive extension may diminish our cognitive lives in different ways. This does not lead to a categorical rejection of cognitive enhancement as unethical or bad for human flourishing, but does warrant a conservative approach to the design and implementation of cognitive artifacts.

P.T. Geach has maintained (see, e.g., Geach (1967/1968)) that identity (as well as dissimilarity) is always relative to a general term. According to him, the notion of absolute identity has to be abandoned and replaced by a multiplicity of relative identity relations for which Leibniz's Law - which says that if two objects are identical they have the same properties - does not hold. For Geach relative identity is at least as good as Frege's cardinality thesis which he takes to (...) be strictly connected with relative identity - according to which an ascription of cardinality is always relative to a concept which specifies what, in any particular case, counts as a unit. The idea that there is a close connection between relative identity and Frege's cardinality thesis has been issued again quite recently by Alston and Bennett in (1984). In their opinion, Frege's cardinality thesis is not only similar to relative identity - as Geach maintains - but it implies it. Moreover, they agree with Geach in claiming that a commitment to Frege's cardinality thesis forces a parallel commitment to relative identity. Against Geach, Alston and Bennett we will claim that (Tl): "Frege's cardinality thesis is similar to relative identity" is false and that therefore (T2) "Frege's cardinality thesis implies relative identity" is false as well.

This article considers how professional knowledge should be assessed. It is maintained that the assessment of professional know-how raises distinctive issues from the assessment of know-how more generally. Intellectualist arguments which suggest that someone's giving an account of how to F should suffice for attributing to them knowledge of how to F are set out. The arguments fail to show that there is no necessary distinction between two kinds of know-how, namely the ability to F and knowing that w is (...) a way to F, such that the latter is more fundamental. The consequences of this failure for our understanding of professional assessment are then considered. The issue of the assessment of tacit knowledge is then addressed. It is concluded that there is no context-dependent codifiable or articulable propositional knowledge of how to F which could be substituted for being able to F and that therefore tacit knowledge can only be assessed in performance. The parallel with Gettier cases is reviewed and it is concluded that the provenance of accounts of and justifications for the attribution of know-how are not matters of indifference to its assessment. Finally, the question of evaluability or what Ryle would have called the applicability of intelligence epithets is discussed in relation to its relevance to our procedures for assessing practical knowledge. Once again, it is concluded that excellent performance is necessary to attribute excellence in know-how. However, the ability to give an account of how and why an agent would do something in hypothetical circumstances is also very important for the assessment of professional knowledge. (shrink)

In English, in order to speak about Arthur’s attitudes, we use sentences like “Arthur believes that natural language is messy”. For sentences of this kind we have a standard theory, according to which the ‘that’-clause ‘that natural language is messy’ denotes a proposition. As Prior showed for the first time, the standard theory appears to be at odds with some linguistic data. Geach and Prior both assumed that linguistic data are to be taken as reliable guides to a correct semantic (...) account and I will start by raising some worries concerning their methodology. Because of these data, Prior and Geach suggested some non-standard accounts. I will then show that if we take linguistic data seriously, their non-standard accounts do not fare any better than the standard theory. My general conclusion will thus not only be that Prior’s and Geach’s methodology is disputable, but also that their conclusions do not seem to follow even if we grant the reliability of their methodology.

The paper explores the distinction between two doctrines, both of which inform theory construction in much of modern cognitive psychology: the representational theory of mind and the computational theory of mind. According to the former, propositional attitudes are to be construed as relations that organisms bear to mental representations. According to the latter, mental processes have access only to formal (nonsemantic) properties of the mental representations over which they are defined.The following claims are defended: (1) That the traditional dispute between (...) “rational” and “naturalistic” psychology is plausibly viewed as an argument about the status of the computational theory of mind. Rational psychologists accept a formality condition on the specification of mental processes; naturalists do not. (2) That to accept the formality condition is to endorse a version of methodological solipsism. (3) That the acceptance of some such condition is warranted, at least for that part of psychology which concerns itself with theories of the mental causation of behavior. This is because: (4) such theories require nontransparent taxonomies of mental states; and (5) nontransparent taxonomies individuate mental states without reference to their semantic properties. Equivalently, (6) nontransparent taxonomies respect the way that the organism represents the object of its propositional attitudes toitself, and it is this representation which functions in the causation of behavior.The final section of the paper considers the prospect for a naturalistic psychology: one which defines its generalizations over relations between mental representations and their environmental causes, thus seeking to account for the semantic properties of propositional attitudes. Two related arguments are proposed, both leading to the conclusion that no such research strategy is likely to prove fruitful. (shrink)

How do we form concepts like those of three, bicycle and red? According to Kant, we form them by carrying out acts of comparison, reflection and abstraction on information provided by the senses. Kant's answer raised numerous objections from philosophers and psychologists alike. "Kant e la formazione dei concetti" argues that Kant is able to rebut those objections. The book shows that, for Kant, it is possible to perceive objects without employing concepts; it explains how, given those perceptions, we can (...) form categories and empirical concepts; and it argues that theories like Kant's - abstractionist theories of concept formation - are more plausible than is often assumed.

What is the relation between norms (in the sense of ?socially accepted rules?) and conventions? A number of philosophers have suggested that there is some kind of conceptual or constitutive relation between them. Some hold that conventions are or entail special kinds of norms (the ?conventions-as-norms thesis?). Others hold that at least some norms are or entail special kinds of conventions (the ?norms-as-conventions thesis?). We argue that both theses are false. Norms and conventions are crucially different conceptually and functionally in (...) ways that make it the case that it is a serious mistake to try to assimilate them. They are crucially different conceptually in that whereas conventions are not normative and are behaviour dependent and desire dependent, norms are normative, behaviour independent, and desire independent. They are crucially different functionally in that whereas conventions principally serve the function of facilitating coordination, norms principally serve the function of making us accountable to one another.

The causal theory of properties is standardly combined with a realist's ontology of universals or tropes. In this paper, I consider an uncharted alternative – a nominalist causal theory of properties. I discuss advantages and disadvantages of the resulting theory of properties, and explore the Rylean understanding of causal powers that emerges.

Quine’s thesis of the indeterminacy of translation has puzzled the philosophical community for several decades. It is unquestionably among the best known and most disputed theses in contemporary philosophy. Quine’s classical argument for the indeterminacy thesis, in his seminal work Word and Object, has even been described by Putnam as “what may well be the most fascinating and the most discussed philosophical argument since Kant’s Transcendental Deduction of the Categories” (Putnam, 1975a: p. 159).

We use quotation marks when we wish to refer to an expression. We can and do so refer even when this expression is composed of characters that do not occur in our alphabet. That's why Tarski, Quine, and Geach's theories of quotation don't work. The proposals of Davidson, Frege, and C. Washington, however, do not provide a plausible account of quotation either. (Section I). The problem is to construct a Tarskian theory of truth for an object language that contains quotation (...) marks, without appealing to quotation marks in the metalanguage. I propose to supply Tarski's truth definition with one axiom that determines the denotation of all expressions containing quotation marks. According to this axiom, quotation marks create a non-extensional context. Since admitting such contexts does not lead to any difficulties in the recursive truth characterization, we may indeed dispense with extensionalism. (Section II). Finally, I argue that we classify and denote expressions in the very same way that we classify and denote extralinguistic entities. Both tokens and types of written signs can be easily incorporated into the naturalist's worldview. (Section III). (shrink)

There are at least four varieties of quotation, including pure, direct, indirect and mixed. A theory of quotation, we argue, should give a unified account of these varieties of quotation. Mixed quotes such as 'Alice said that life is 'difficult to understand'', in which an utterance is directly and indirectly quoted concurrently, is an often overlooked variety of quotation. We show that the leading theories of pure, direct, and indirect quotation are unable to account for mixed quotation and therefore unable (...) to provide a unified theory. In the second half of the paper we develop a unified theory of quotation based on Davidson's demonstrative theory. 'Language is the instrument it is because the same expression, with semantic features (meaning) unchanged, can serve countless purposes.' (Davidson 1968). (shrink)

Some philosophers have conflated functionalism and computationalism. I reconstruct how this came about and uncover two assumptions that made the conflation possible. They are the assumptions that (i) psychological functional analyses are computational descriptions and (ii) everything may be described as performing computations. I argue that, if we want to improve our understanding of both the metaphysics of mental states and the functional relations between them, we should reject these assumptions. # 2004 Elsevier Ltd.

Several arguments for combinatorial structure in mental representations are then reviewed. These include arguments based on the ‘systematicity’ of mental representation: i.e., on the fact that cognitive capacities always exhibit certain symmetries, so that the ability to entertain a given thought implies the ability to entertain thoughts with semantically related contents. We claim that such arguments make a powerful case that mind/brain architecture is not Connectionist at the cognitive level. We then consider the possibility that Connectionism may provide an account of the neural (or ‘abstract neurological’) structures in which Classical cognitive architecture is implemented.

In this paper I highlight certain logical and metaphysical issues which arise in the characterisation of functionalism-in particular its ready coherence with a physicalist ontology, its structuralism and the impredicativity of functionalist specifications. I then utilise these points in an attempt to demonstrate fatal flaws in the functionalist programme. I argue that the brand of functionalism inspired by David Lewis fails to accommodate multiple realisability though such accommodation was vaunted as a key improvement over the identity theory. More standard accounts (...) of functionalism allow, by contrast, for far too much multiple realisability. Specifically, functionalist structures will be massively reduplicated in the human brain; so functionalism yields the absurd consequence that each human harbours large numbers of minds and exemplifies virtually all mental states.

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statis- tics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement record- ing systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During perceptual experience, association areas in the (...) brain capture bottom-up patterns of activation in sensory-motor areas. Later, in a top-down manner, association areas partially reactivate sensory-motor areas to implement perceptual symbols. The stor- age and reactivation of perceptual symbols operates at the level of perceptual components – not at the level of holistic perceptual expe- riences. Through the use of selective attention, schematic representations of perceptual components are extracted from experience and stored in memory (e.g., individual memories of green, purr, hot). As memories of the same component become organized around a com- mon frame, they implement a simulator that produces limitless simulations of the component (e.g., simulations of purr). Not only do such simulators develop for aspects of sensory experience, they also develop for aspects of proprioception (e.g., lift, run) and introspec- tion (e.g., compare, memory, happy, hungry). Once established, these simulators implement a basic conceptual system that represents types, supports categorization, and produces categorical inferences. These simulators further support productivity, propositions, and ab- stract concepts, thereby implementing a fully functional conceptual system. Productivity results from integrating simulators combinato- rially and recursively to produce complex simulations. Propositions result from binding simulators to perceived individuals to represent type-token relations. Abstract concepts are grounded in complex simulations of combined physical and introspective events. Thus, a per- ceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal sym- bol systems. Implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored. (shrink)

Friederike Moltmann has recently proposed an account of truth-bearers that draws on Kazimierz Twardowski’s action/product distinction. Her account is meant to provide a third way between the dominant view of primary truth-bearers as mind-independent entities and the recently revived construal of them as mental or linguistic acts. This paper argues that there is no room for Twardowskian accounts because they are based on a notion of “nonenduring product” that defies comprehension, and no need for them because the linguistic data that (...) Twardowskians take to refute the act-theoretic approach can, in fact, be handled by that approach. (shrink)

Doxastic involuntarists have paid insufficient attention to two debates in contemporary epistemology: the permissivism debate and the debate over norms of assertion and belief. In combination, these debates highlight a conception of belief on which, if you find yourself in what I will call an ‘equipollent case’ with respect to some proposition p, there will be no reason why you can’t believe p at will. While doxastic involuntarism is virtually epistemological orthodoxy, nothing in the entire stock of objections to belief (...) at will blocks this route to doxastic voluntarism. Against the backdrop of the permissivism debate and the literature on norms of belief and assertion, doxastic involuntarism emerges as an article of faith, not the obvious truth it’s usually purported to be.

The focus of this paper are Dummett's meaning-theoretical arguments against classical logic based on consideration about the meaning of negation. Using Dummettian principles, I shall outline three such arguments, of increasing strength, and show that they are unsuccessful by giving responses to each argument on behalf of the classical logician. What is crucial is that in responding to these arguments a classicist need not challenge any of the basic assumptions of Dummett's outlook on the theory of meaning. In particular, I (...) shall grant Dummett his general bias towards verificationism, encapsulated in the slogan 'meaning is use'. The second general assumption I see no need to question is Dummett's particular breed of molecularism. Some of Dummett's assumptions will have to be given up, if classical logic is to be vindicated in his meaning-theoretical framework. A major result of this paper will be that the meaning of negation cannot be defined by rules of inference in the Dummettian framework. (shrink)

Two related arguments are proposed, both leading to the conclusion that no such research strategy is likely to prove fruitful. (shrink)
