The purpose of the paper is twofold. I first outline a philosophical theory of concepts based on conceptual role semantics. This approach is explicitly intended as a framework for the study and explanation of conceptual change in science. Then I point to the close similarities between this philosophical framework and the theory theory of concepts, suggesting that a convergence between psychological and philosophical approaches to concepts is possible. An underlying theme is to stress that using a non-atomist account of concepts (...) is crucial for the successful study of conceptual development and change. (shrink)

CRS says that the meanings of expressions of a language or other symbol system or the contents of mental states are determined and explained by the way symbols are used in thinking. According to CRS one.

I argue that logical understanding is not propositional knowledgebut is rather a species of practical knowledge. I further arguethat given the best explanation of logical understanding someversion or another of inferential role semantics must be the correct account of the determinants of logical content.

A comprehensive introduction to the Language of Though Hypothesis (LOTH) accessible to general audiences. LOTH is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in (...) syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

Our perception of external features comprises, among others, functional and phenomenological levels. At the functional level, the perceiver’s mind processes external features according to its own causal- functional organization. At the phenomenological level, the perceiver has consciousness of external features. The question of this paper is: How do the functional and the phenomenological levels of perception relate to each other? The answer I propose is that functional states of specifically perceptual attention constitute the necessary basis for the arising of consciousness (...) in a perceiver. -/- Widely studied within cognitive psychology, perceptual attention is still awaiting a thoroughgoing philosophical treatment. The paper presents and draws upon Anne Treisman’s feature-integration theory of attention (cf. A. Treisman & G. Gelade, “A Feature-Integration Theory of Attention,” Cognitive Psychology, 12, 1980. Pp. 97-136). According to this theory, attentional mechanisms are responsible for the binding of perceptual features into coherent and stable objects of perception. By itself, I will claim, the theory of feature integration does not allow a straightforward reduction of consciousness to the functional processing underlying it. However, on the basis of Treisman’s theory we can produce a methodological argument for endorsing the non-reductivist thesis that attentional states constitute the necessary basis for the arising of consciousness in a perceiver. The paper closes by presenting this argument, according to which the thesis is implied by a unified account of the common representational natures of attentional and conscious states. (shrink)

This paper aims to investigate the temporal content of perceptual experience. It argues that we must recognize the existence of temporal perceptions, i.e., perceptions the content of which cannot be spelled out simply by looking at what is the case at an isolated instant. Acts of apprehension can cover a succession of events. However, a subject who has such perceptions can fall short of having a concept of time. Similar arguments have been put forward to show that a subject who (...) has spatial perceptions can fall short of having a concept of space. In both cases, it is the fact that perception is from a point of view which stands in the way of it constituting an exercise of a concept of how things are objectively. However, the paper also shows that the way in which perception is perspectival takes a different form in each of the two cases. (shrink)

Consciousness is a mongrel concept: there are a number of very different "consciousnesses." Phenomenal consciousness is experience; the phenomenally conscious aspect of a state is what it is like to be in that state. The mark of access-consciousness, by contrast, is availability for use in reasoning and rationally guiding speech and action. These concepts are often partly or totally conflated, with bad results. This target article uses as an example a form of reasoning about a function of "consciousness" based on (...) the phenomenon of blindsight. Some information about stimuli in the blind field is represented in the brains of blindsight patients, as shown by their correct "guesses," but they cannot harness this information in the service of action, and this is said to show that a function of phenomenal consciousness is somehow to enable information represented in the brain to guide action. But stimuli in the blind field are BOTH access-unconscious and phenomenally unconscious. The fallacy is: an obvious function of the machinery of access-consciousness is illicitly transferred to phenomenal consciousness. (shrink)

This paper explores the relation between two ways of thinking about the sources of self-consciousness. We can think about the sources of self-consciousness either in genetic terms (as the origins or precursors of self-conscious thoughts) or in epistemic terms (as the grounds of self-conscious judgements). Using Christopher Peacocke's account of self-conscious judgements in Being Known as a foil, this paper brings out some important ways in which we need to draw upon the sources of self-consciousness in the genetic sense for (...) a proper understanding of the sources of self-consciousness in the epistemic sense.

Are there different constraints on theories of conscious experience as against theories of conscious propositional thought? Is what is problematic or puzzling about each of these phenomena of the same, or of different, types? And to what extent is it plausible to think that either or both conscious experience and conscious thought involve some sort of selfreference? In pursuing these questions I shall also explore the prospects for a defensible form of eliminativism concerning conscious thinking, one that would leave the (...) reality of conscious experience untouched. In the end, I shall argue that while there might be no such thing as conscious judging or conscious wanting, there is (or may well be) such a thing as conscious generic thinking. (shrink)

I propose a counterexample to naturalistic representational theories of phenomenal character. The counterexample is generated by experiences of novel colours reported by Crane and Piantanida. I consider various replies that a representationalist might make, including whether novel colours could be possible colours of objects and whether one can account for novel colours as one would account for binary colours or colour mixtures. I argue that none of these strategies is successful and therefore that one cannot fully explain the nature of (...) the phenomenal character of perceptual experiences using a naturalistic conception of representation.

_Consciousness, Color, and Content_ is a significant contribution to our understanding of consciousness, among other things. I have learned a lot from it, as well as Tye.

This article replies to the main objections raised by the commentators on Carruthers . It discusses the question of what evidence is relevant to the assessment of dispositional higher-order thought theory; it explains how the actual properties of phenomenal consciousness can be dispositionally constituted; it discusses the case of pains and other bodily sensations in non-human animals and young children; it sketches the case for preferring higher-order to first-order theories of phenomenal consciousness; and it replies to some miscellaneous points and (...) objections.

Frank Jackson’s knowledge argument is a very influential piece of reasoning that seeks to show that colour experiences constitute an insoluble problem for science. This argument is based on a thought experiment concerning Mary. She is a vision scientist who has complete scientific knowledge of colours and colour vision but has never had colour experiences. According to Jackson, upon seeing coloured objects, Mary acquires new knowledge that escapes her complete scientific knowledge. He concludes that there are facts concerning colour experiences (...) that scientific knowledge can neither describe nor explain. Specifically, these facts involve the occurrence of certain non-physical properties of experiences that he calls qualia. The present research considers whether a plausible formulation of the hypothesis that science can accommodate colour experiences is threatened by a version of the knowledge argument. The specific formulation of this problem has two motivations. Firstly, before investigating whether the knowledge argument raises a problem for the claim that science can account for colour experiences, we need a plausible formulation of this claim. I argue that the idea that science can accommodate colour experiences can be formulated as the modest reductionism hypothesis. Roughly speaking, this is the hypothesis that a science that can be explanatory interfaced with current physics of ordinary matter can account for conscious experiences. Secondly, an unintelligible premise figures in Jackson’s version the knowledge argument. Namely, it is assumed that Mary possesses a complete scientific knowledge. Nevertheless, the type of strategy involved in Jackson’s argument can be used to target modest reductionism. By considering contemporary psychophysics and neuroscience, I characterise Mary’s scientific knowledge. First, this characterisation is intelligible. In fact, it is elaborated on the basis of descriptions and explanations of colour experiences involved in current physics and neuroscience. Second, a supporter of modest reductionism can assume that the scientific knowledge ascribed to Mary might account for colour experiences. The main conclusion of the present research is that our version of the knowledge argument fails to threaten the modest reductionism hypothesis. In fact, I endorse what can be called the “two ways of thinking” reply to the knowledge argument. According to this response, the knowledge argument shows that there are different ways of thinking about colour experiences. One way of thinking is provided by scientific knowledge. The other way of thinking is provided by our ordinary conception of colour experiences. However, the existence of these two ways of thinking does not imply the existence of facts and properties that escape scientific knowledge. It might be the case that the ordinary way of thinking about colour experience concerns facts and properties described and explained by science. The principal conclusion of the research results from two investigations. The first line of research aims to reveal and evaluate the implicit assumptions that figure in the knowledge argument. The main body of the research is dedicated to this task. The principal result of this investigation is that the knowledge argument must rely on an account of introspective knowledge of colour experiences. I argue that an inferential model of introspection provides such account. On this model, Mary’s capacity to hold beliefs about her colour experiences when she sees coloured objects requires her mastery of colour concepts. The second main investigation seeks to justify the two ways of thinking strategy. As many opponents and supporters have recently started to realise, this strategy might be charged with being ad hoc. I offer a distinctive justification of this reply to the knowledge argument. Assuming the account of introspection mentioned above, the existence of visual recognitional colour concepts might justify this strategy. A person possesses these concepts when she is able to determine the colours of objects simply by having visual experiences. (shrink)

Modal intuitions are the primary source of modal knowledge but also of modal error. According to the theory of modal error in this paper, modal intuitions retain their evidential force in spite of their fallibility, and erroneous modal intuitions are in principle identifiable and eliminable by subjecting our intuitions to a priori dialectic. After an inventory of standard sources of modal error, two further sources are examined in detail. The first source - namely, the failure to distinguish between metaphysical possibility (...) and various kinds of epistemic possibility - turns out to be comparatively easy to untangle and poses little threat to intuition-driven philosophical investigation. The second source is the local misunderstanding of one's concepts . This pathology may be understood on analogy with a patient who is given a clean bill of health at his annual check-up, despite his having a cold at the time of the check-up: although the patient's health is locally disrupted, his overall health is sufficiently good to enable him to overcome the cold without external intervention. Even when our understanding of certain pivotal concepts has lapsed locally, our larger body of intuitions is sufficiently reliable to allow us, without intervention, to ferret out the modal errors resulting from this lapse of understanding by means of dialectic and/or a process of a priori reflection. This source of modal error, and our capacity to overcome it, has wide-ranging implications for philosophical method - including, in particular, its promise for disarming skepticism about the classical method of intuition-driven investigation itself. Indeed, it is shown that skeptical accounts of modal error are ultimately self-defeating. (shrink)

Jackson's black-and-white Mary teaches us that the propositional content of perception cannot be fully expressed in language.

Charles Siewert has given us an ingenious thought experiment involving a limited lack of conscious experience. The possibility of the described case is incompatible with a number of popular theories of consciousness. Siewert acknowledges, however, that this possibility is not a direct threat to "hidden feature" theories. I aim to do two things: first, strengthen his defense of the claim that the case is genuinely possible by considering and rejecting some further attempts to explain away our temptation to believe it (...) possible; and second, to explore how a hidden feature approach could be developed and made plausible.

It has been argued that our concepts can be disrupted or challenged by technology or normative concerns, which raises the question of whether we can create, design, engineer, or define more robust concepts that avoid counterexamples and conceptual challenges that can lead to conceptual disruption. In this paper, it is argued that we can. This argument is presented through a case study of a definition in the technological domain.

In this paper I develop an argument against a type of Non-Analytic Normative Naturalism. This argument, the Normative Property Dualism Argument, suggests that, if Non-Analytic Normative Naturalists posit that normative properties are identical to natural properties and that such identities are a posteriori, they will be forced to posit that these properties which are both normative and natural have higher-order normative properties of their own.

According to certain views about human ontology, the way we seem is very different from the way we are. The appearances are a threat to such views. Here I take up and defuse the threat to one such view.Pure immaterialism says that each of us is wholly immaterial. The appearances suggest otherwise. I argue that despite the fact that we might sometimes appear to be at least partly material, and that we can be perceptually justified in believing something solely on (...) the basis of having a perceptual experience as of its being the case, none of us is ever perceptually justified in believing that we are even partly material (or that we’re not). Bottom line: we might be able to know whether we’re material, but we can’t know just by looking. (shrink)

The target article argues that language-of-thought hypothesis (LoTH) is applicable to various domains, including perception. However, it focusses exclusively on the visual case, which is limited in this regard. I argue for two ideas in this commentary: first, their case can be extended to other modalities such as touch; and second, the status of those six criteria needs to be further clarified.

This paper connects the debate regarding perceptual representation of high-level properties and the debate regarding non-conceptual perceptual representation. I present and defend a distinction between representationally-complex properties and properties that are simpler to represent and offer ways of assessing whether a property is representationally complex. I address conditions under which such a property might be non-conceptually represented and conclude that most representationally-complex properties are simply too complex to be non-conceptually represented. Thus, most mental states that represent representationally-complex properties must be (...) conceptual. This conclusion is relevant for a variety of philosophical theories (perception, ethics, emotions, pain) and is especially dramatic with respect to accounts according to which a mental state can non-conceptually represent such properties. As a test case for applying my argument I consider a group of such accounts: non-conceptual perceptual views of emotions, which my argument entails are false. I end by considering the implications my argument has for different theories. -/- . (shrink)

Imagine coming across an alternative community such that, while they have normative terms like 'ought' with the same action-guiding roles and relationships to each other, their normative terms come to pick out different properties. When we come across such a community, or even just imagine it, those of us who strive to be moral and rational want to ask something like the following: Further Question: Which set of concepts ought we use—theirs or ours? The problem, first raised by Eklund, is (...) that on almost any metasemantic theory, Further Question cannot be stated in a way that captures the spirit of what we want to ask. This is because any way of asking the question makes use of our own normative concepts, and thus their reference is already fixed on the properties that our current normative concepts refer to. Any purported solution to this problem must meet two conditions. First, it must capture the spirit of what Further Question is intuitively attempting to ask. Second, it must reframe the inquiry in a way that makes the answer neither trivial nor ineffable. In this paper, I propose a solution to this problem by appeal to edenic representation, inspired by, but not identical to, Chalmers’ notion of edenic content. The rough idea here is that representation is edenic to the extent that the representational vehicle mirrors, in quality and structure, the represented property. I argue that a reframing of Further Question in terms of edenic representation can capture the spirit of the question, without collapsing it into a question with a trivial or ineffable answer. Thus, the realist about normative properties can face the problem of the alternative normative community head on, without collapsing into incoherence or triviality. If correct, this solution is of further interest to any metanormative realist concerned with metasemantic questions, because it can tell us more about how the proper representation of the robustly normative would look.

I review proposed skepticisms in recent literature (or skeptical invariantisms, if we understand skepticism semantically), contrast their basic commitments and highlight some of their comparative theoretical attractions and problems. To help set the scene for the discussion, I start with Unger’s (1975) modern classic of global skepticism about knowledge (and justification). I then distinguish three extant categories of skepticism in the recent literature: two non‐traditional and one more traditional. On the non‐traditional side are fallibilist science‐based skepticism (which relaxes the stringency (...) of the standard of knowledge) and practical skepticism (which questions the intellectual character of the standard of knowledge) and on the traditional side high‐standard/infallibilist. I then briefly present and discuss representatives of each category. (shrink)

Traditional rationalist approaches to a priori epistemology have long been looked upon with suspicion for positing a faculty of rational intuition capable of knowing truths about the world apart from experience. Conceptualists have tried to fill this void with something more empirically tractable, arguing that we know a priori truths due to our understanding of concepts. All of this theorizing, however, has carried on while neglecting an entire cross section of such truths, the grounding claims that we know a priori. (...) Taking a priori grounding into account poses a significant challenge to conceptualist accounts of a priori knowledge, as it is unclear how merely understanding conceptual connections can account for knowledge of grounding. The fact that we do know some grounding truths a priori, then, is a significant mark in traditional rationalism’s favor, and the next frontier for those who aim to eliminate the mystery surrounding a priori knowledge.

Philosophers of music, like Charles Swann in Proust’s novel (Proust 1913/1992, p. 360), have traditionally found it difficult to utter the word ‘profound’ unironically. But this changed with Peter Kivy’s 1990 paper ‘The profundity of music’ The problem Kivy draws our attention to is this: we do call some musical works profound. However, Kivy argues, given that a work is profound only if it is about something profound and given that music (or ‘music alone’) is not about anything, this leads (...) to something of a paradox: how can music be profound if it is not about something profound. My aim in this paper is to argue that what makes a work profound is not that it is about something profound, but that it actively challenges any straightforward interpretative activity (while at the same time nudges you to keep on trying to interpret it). I argue that this line of argument is very much in tune with Kivy’s general theoretical commitment that “music alone isn’t about anything” (Kivy 1990, p. 245). (shrink)

Recent discussions have fixated on the distinction between perception and cognition. How should recognition be understood in light of this distinction? The relevant sense of recognition involves a sensitivity to particulars from one's past. Recognizing the face of a familiar friend is one instance of this phenomenon, as is recognizing an object or place that one has viewed before. In this article, I argue that recognition is an interface capacity that straddles the border between perception and cognition.

In the light of partial (mis)understanding, we examine the thesis that concepts are individuated in terms of possession conditions and show that adherents face a fatal dilemma: Either concept‐individuating possession conditions include cases of partially (mis)understood concepts or not. If yes, possession conditions do not individuate concepts. If no, the thesis is too restricted and lacks a minimally satisfactory level of generalization.

When someone masters a skill, their performance looks to us like second nature: it looks as if their actions are smoothly performed without explicit, knowledge-driven, online monitoring of their performance. Contemporary computational models in motor control theory, however, are instructionist: that is, they cast skillful performance as a knowledge-driven process. Optimal motor control theory, as representative par excellence of such approaches, casts skillful performance as an instruction, instantiated in the brain, that needs to be executed—a motor command. This paper aims (...) to show the limitations of such instructionist approaches to skillful performance. We specifically address the question of whether the assumption of control-theoretic models is warranted. The first section of this paper examines the instructionist assumption, according to which skillful performance consists of the execution of theoretical instructions harnessed in motor representations. The second and third sections characterize the implementation of motor representations as motor commands, with a special focus on formulations from OMCT. The final sections of this paper examine predictive coding and active inference—behavioral modeling frameworks that descend, but are distinct, from OMCT—and argue that the instructionist, control-theoretic assumptions are ill-motivated in light of new developments in active inference.

This thesis is about the metaphysics of logic. I argue against a view I refer to as ‘logical realism’. This is the view that the logical constants represent a particular kind of metaphysical structure, which I dub ‘logico-metaphysical structure’. I argue instead for a more metaphysically lightweight view of logic which I dub ‘logical expressivism’. -/- In the first part of this thesis (Chapters I and II) I argue against a number of arguments that Theodore Sider has given for logical (...) realism. In Chapter I, I present an argument of his to the effect that logico-metaphysical structure provides the only good explanation of the semantic determinacy of the logical constants. I argue that other explanations are possible. In Chapter II, I present another argument of his to the effect that logico-metaphysical structure is something that comes along with ontological realism: the view that there is a non-language-relative fact of the matter about what exists. I argue that the connection between logical and ontological realism is not as close as Sider makes it out to be. -/- In the second part of this thesis (Chapters III – V) I set out a positive view of the logical constants that can explain both why their meanings are semantically determinate, and why they form part of our vocabulary. On that view, the primary bearers of logical structure are propositional attitudes, and the logical constants are in our language as vehicles for the expression of logically complex propositional attitudes. In Chapter III, I set out an expressivist theory of propositional logic. In Chapter IV, I use this theory to explain how the logical connectives end up having determinate meanings. In Chapter V, I extend the expressivist theory to predicate logic. (shrink)

Several philosophers think there are important analogies between emotions and perceptual states. Furthermore, considerations about the rational assessibility of emotions have led philosophers—in some cases, the very same philosophers—to think that the content of emotions must be propositional content. If one finds it plausible that perceptual states have propositional contents, then there is no obvious tension between these views. However, this view of perception has recently been attacked by philosophers who hold that the content of perception is object‐like. I shall (...) argue for a view about the content of emotions and perceptual states which will enable us to hold both that emotional content is analogous to perceptual content and that both emotions and perceptual states can have propositional contents. This will involve arguing for a pluralist view of perceptual content, on which perceptual states can have both contents which are proposition‐like and contents which are object‐like. I shall also address two significant objections to the claim that emotions can have proposition‐like contents. Meeting one of these objections will involve taking on a further commitment: the pluralist account of perceptual content will have to be one on which the contents of perception can be non‐conceptual.

Phenomenal objectivism explains perceptual phenomenal character by reducing it to an awareness of mind-independent objects, properties, and relations. A challenge for this view is that there is a sense in which a distant tree looks smaller than a closer tree even when they are the same objective size (perceptual size variation). The dual content view is a popular objectivist account in which such experiences are explained by my objective spatial relation to the tree, in particular visual angle (perspectival size). I (...) describe a series of first-person experiments for investigating size experience. I use a ruler as a first-person method for operationalising perspectival size (Experiment 1). I use the corridor illusion (Experiment 2), outlining one’s head in the mirror (Experiment 3), and outlining the size of objects on glass (Experiment 4) to show a phenomenal difference in size for items in different depth contexts, despite being identical in visual angle. These finding demonstrate that visual angle cannot account for these spatial experiences. Psychological evidence provides further support for the thesis that subjects do not experience visual angle when depth information is present. Together this evidence supports the hypothesis that perceptual size variation cannot be accounted for by visual angle, hence undermining a plausible version of the dual content theory. This outcome, combined with problems raised by alternative objectivist accounts of size variation, provides support for a subjectivist account of size experience. (shrink)

Consider the Unshareability View, namely, the view that first person thought or self-thought—thought as typically expressed via the first person pronoun—is not shareable from subject to subject.

Neuroscientific scanning of meditators is taken as providing data on mystical experiences. However, problems concerning how the brain and consciousness are related cast doubts on whether any understanding of the content of meditative experiences is gained through the study of the brain.

So too, whether current neuroscience can establish that there are “pure consciousness events” in mysticism is open to question. The discussion points to limitations (...) on neuroscience's capability to add to our understanding of the phenomenological content of mystical experiences. (shrink)

Do we think in a language-like format? Taking the marker of language-like formats to be the property of unconstrained systematicity, this paper considers the following master argument for the claim that we do: language is unconstrainedly systematic, if language is unconstrainedly systematic then so is thought, so thought is unconstrainedly systematic. It is easy to feel that there is something right about this argument, that there will be some way of filling in its details that will vindicate the idea that (...) our thought must be unconstrainedly systematic given that the language in which we express it is. Clearly, however, the second premise needs support—we need a principled reason for moving from the unconstrained systematicity of language to the unconstrained systematicity of thought. This paper gives three passes at formulating such a principle. This turns out to be much harder than it might seem. We should, I conclude, resist falling too easily for the lure of this master argument for the language-like format of thought. (shrink)

Paraconsistent dialetheism is the view that some contradictions are true and that the inference rule ex falso quod libet is invalid. A long-standing problem for paraconsistent dialetheism is that it has difficulty making sense of situations where people use locutions like ‘just true’ and ‘just false’. Jc Beall recently advocated a general strategy, which he terms shrieking, for solving this problem and thereby strengthening the case for paraconsistent dialetheism. However, Beall’s strategy fails, and seeing why it fails brings into greater (...) focus just how daunting the just-true problem is for the dialetheist. (shrink)

This paper develops a theory of perception that reconciles representationalism and relationalism by relying on pragmatist ideas. I call it the pragmatic view of perception. I argue that fully reconciling representationalism and relationalism requires, first, providing a theory in which how we perceive the world involves representations; second, preserving the idea that perception is constitutively shaped by its objects; and third, offering a direct realist account of perception. This constitutes what I call the Hybrid Triad. I discuss how Charles Peirce’s (...) theory of perception can provide a framework for such a view and I devote the rest of the paper to developing my own pragmatic and Peircean theory of perception. In particular, I argue that considering perception as a continuous temporal process, which essentially involves interaction with the environment, allows us to do justice to the Hybrid Triad. I motivate this view by discussing how a pragmatic theory of perception would deal with issues such as the distinction between veridical and non-veridical experiences and the nature of perceptual objects.

This thesis comprises three main chapters—each comprising one relatively standalone paper. The unifying theme is fragmentalism about truth, which is the view that the predicate “true” either expresses distinct concepts or expresses distinct properties. -/- In Chapter 1, I provide a formal development of alethic pluralism. Pluralism is the view that there are distinct truth properties associated with distinct domains of subject matter, where a truth property satisfies certain truth-characterizing principles. On behalf of pluralists, I propose an account of logic (...) and semantics that shows how they can answer central conceptual and logical challenges for their view. -/- In Chapter 2, I motivate and develop a modal account of propositions on the basis of an iterative conception of propositions, where the modality is logico-mathematical. The modal account of propositions takes the conception to motivate an inherently potential hierarchy of propositions. I show that the account helps provide satisfying solutions to the intensional paradoxes of Russell-Myhill, Kaplan, and Prior. -/- In Chapter 3, I propose that “true” is polysemous. I suggest that “true” is initially polysemous between correspondence truth and disquotational truth, and further polysemous between the meanings corresponding to the subconcepts of the concept truth generated by the indefinite extensibility of that concept. I show that the proposal provides satisfying solutions to the semantic paradoxes. (shrink)

The distinction between perception and cognition has always had a firm footing in both cognitive science and folk psychology. However, there is little agreement as to how the distinction should be drawn. In fact, a number of theorists have recently argued that, given the ubiquity of top-down influences, we should jettison the distinction altogether. I reject this approach, and defend a pluralist account of the distinction. At the heart of my account is the claim that each legitimate way of marking (...) a border between perception and cognition deploys a notion I call ‘stimulus-control.’ Thus, rather than being a grab bag of unrelated kinds, the various categories of the perceptual are unified into a superordinate natural kind.

Representationalism is the position that the phenomenal character of an experience is either identical with, or supervenes on, the content of that experience. Many representationalists hold that the relevant content of experience is nonconceptual. I propose a counterexample to this form of representationalism that arises from the phenomenon of Gestalt switching, which occurs when viewing ambiguous figures. First, I argue that one does not need to appeal to the conceptual content of experience or to judgements to account for Gestalt switching. (...) I then argue that experiences of certain ambiguous figures are problematic because they have different phenomenal characters but that no difference in the nonconceptual content of these experiences can be identified. I consider three solutions to this problem that have been proposed by both philosophers and psychologists and conclude that none can account for all the ambiguous figures that pose the problem. I conclude that the onus is on representationalists to specify the relevant difference in content or to abandon their position. (shrink)

I here present and defend what I call the Triviality Theory of Truth, to be understood in analogy with Matti Eklund’s Inconsistency Theory of Truth. A specific formulation of is defended and compared with alternatives found in the literature. A number of objections against the proposed notion of meaning-constitutivity are discussed and held inconclusive. The main focus, however, is on the problem, discussed at length by Gupta and Belnap, that speakers do not accept epistemically neutral conclusions of Curry derivations. I (...) first argue that the facts about speakers’ reactions to such Curry derivations do not constitute a problem for the Triviality Theory specifically. Rather, they follow from independent, uncontroversial facts. I then propose a solution which coheres with the theory as I understand it. Finally, I consider a normative reading of their objection and offer a response. (shrink)
