Use theories of meaning (UTMs) seem ill-equipped to accommodate the intuition that ignorant but deferential speakers use natural kind terms (e.g. 'zinc') and technical expression (e.g. 'credit default swap') with the same meanings as the experts do. After all, their use deviates from the experts', and if use determines meaning, a deviant use ordinarily would determine a deviant meaning. Yet the intuition is plausible and advocates of UTMs believe it can be accommodated. I examine Gilbert Harman's and Paul Horwich's views, (...) and argue that they do not offer a satisfactory reconciliation of the intuition with the theory. I propose an accommodation based on a novel account of semantic deference, and show that it is consistent with UTMs that a speaker may use a word with a certain meaning without fully or adequately knowing it.

This essay continues my investigation of `syntactic semantics': the theory that, pace Searle's Chinese-Room Argument, syntax does suffice for semantics (in particular, for the semantics needed for a computational cognitive theory of natural-language understanding). Here, I argue that syntactic semantics (which is internal and first-person) is what has been called a conceptual-role semantics: The meaning of any expression is the role that it plays in the complete system of expressions. Such a `narrow', conceptual-role semantics is the appropriate sort of semantics (...) to account (from an `internal', or first-person perspective) for how a cognitive agent understands language. Some have argued for the primacy of external, or `wide', semantics, while others have argued for a two-factor analysis. But, although two factors can be specified–-one internal and first-person, the other only specifiable in an external, third-person way–-only the internal, first-person one is needed for understanding how someone understands. A truth-conditional semantics can still be provided, but only from a third-person perspective. (shrink)

In the literature seeking to explain concepts in terms of their point, talk of ‘the point’ of concepts remains under-theorised. I propose a typology of points which distinguishes practical, evaluative, animating, and inferential points. This allows us to resolve tensions such as that between the ambition of explanations in terms of the points of concepts to be informative and the claim that mastering concepts requires grasping their point; and it allows us to exploit connections between types of points to understand (...) why they come apart, and whether they do so for problematic ideological reasons or for benignly functional reasons.

Cappelen proposes a radically externalist framework for conceptual engineering. This approach embraces the following two theses. Firstly, the mechanisms that underlie conceptual engineering are inscrutable: they are too complex, unstable and non-systematic for us to grasp. Secondly, the process of conceptual engineering is largely beyond our control. One might think that these two theses are peculiar to the Austerity Framework, or to metasemantic externalism more generally. However, Cappelen argues that there is no reason to think that internalism avoids either commitment. (...) Cappelen argues that to do so she must provide arguments for 3 claims: there are inner states that are scrutable and within our control; concepts supervene on these inner states; and the determination relation from supervenience base to content is itself scrutable and within our control. In this paper, I argue that internalist conceptual role theories of content can meet Cappelen’s challenge. (shrink)

A semantic theory is committed to semantic monism just in case every particular semantic property posited by the theory is a member of the same kind. The commitment to semantic monism appears to draw some support from the need to provide a compositional semantics, since taking a single kind of semantic property as key to a semantic theory affords a uniform pattern on the basis of which the meaning of any given sentence can be compositionally determined. This line of support (...) highlights a tension between the principle of compositionality and taking a more pluralistic approach to semantic theorizing. In this essay, that tension is relieved, leaving open the prospect of a pluralistic semantic theory that observes the principle of compositionality. (shrink)

Each of our theories of mental representation provides some insight into how the mind works. However, these insights often seem incompatible, as the debates between symbolic, dynamical, emergentist, sub-symbolic, and grounded approaches to cognition attest. Mental representations—whatever they are—must share many features with each of our theories of representation, and yet there are few hypotheses about how a synthesis could be possible. Here, I develop a theory of the underpinnings of symbolic cognition that shows how sub-symbolic dynamics may give rise (...) to higher-level cognitive representations of structures, systems of knowledge, and algorithmic processes. This theory implements a version of conceptual role semantics by positing an internal universal representation language in which learners may create mental models to capture dynamics they observe in the world. The theory formalizes one account of how truly novel conceptual content may arise, allowing us to explain how even elementary logical and computational operations may be learned from a more primitive basis. I provide an implementation that learns to represent a variety of structures, including logic, number, kinship trees, regular languages, context-free languages, domains of theories like magnetism, dominance hierarchies, list structures, quantification, and computational primitives like repetition, reversal, and recursion. This account is based on simple discrete dynamical processes that could be implemented in a variety of different physical or biological systems. In particular, I describe how the required dynamics can be directly implemented in a connectionist framework. The resulting theory provides an “assembly language” for cognition, where high-level theories of symbolic computation can be implemented in simple dynamics that themselves could be encoded in biologically plausible systems.

Teleosemantics explains mental representation in terms of biological function and selection history. One of the main objections to the account is the so-called ‘Swampman argument’ (Davidson 1987), which holds that there could be a creature with mental representation even though it lacks a selection history. A number of teleosemanticists reject the argument by emphasising that it depends on assuming a creature that is fi ctitious and hence irrelevant for teleosemantics because the theory is only concerned with representations in real-world organisms (...) (Millikan 1996, Neander 1996, 2006, Papineau 2001, 2006). I contend that this strategy doesn’t succeed. I off er an argument that captures the spirit of the original Swampman objection but relies only on organisms found in the actual world. Th e argument undermines the just mentioned response to the Swampman objection, and furthermore leads to a particular challenge to strong representationalist theories of consciousness that endorse teleosemantics such as, e.g., Dretske’s (1995) and Tye’s (1995, 2000) accounts. On these theories, the causal effi cacy of consciousness in actual creatures will be undermined. (shrink)

Two-Factor conceptual role theories of mental content are often intended to allow mental representations to satisfy two competing requirements. One is the Fregean requirement that two representations, like public language expressions, can have different meanings even though they have the same reference (as in the case of ‘morning star’ and ‘evening star’). The other is Putnam's Twin-earth requirement that two representations or expressions can have the same conceptual role but differ in meaning due to differing references. But I argue that (...) the hidden agenda behind these theories is to make misrepresentation possible. A simple, one-factor conceptual role theory (like the "crude causal theory" Fodor describes) falls prey to the disjunction problem. If every use or application of a concept is meaning-determining, then there can be no misuse of that concept. Each use will partially determine its meaning, and, use which is covered in the meaning cannot be a misuse, error, or misrepresentation. I argue that the referential factor in two-factor conceptual role theories is what is supposed to make misrepresentation possible. But it fails to do so, because when the two factors do not determine the same meaning, there is no non-question-begging way to have one of them take precedence and force meaning to align with one factor and deviate from the other.

The question must arise whether a doctrine which is attributed to all of Quine, Putnam, Davidson, Rorty, Gadamer, and Heidegger is possibly a doctrine which comes in more than one version. Even the most ardent taxonomist is likely to draw back from classifying the various actual and possible positions which emerge from the very tangled history of recent discussions of holism. This chapter approaches the matter by addressing a series of questions, starting with those which are most likely to arise (...) in the mind of those philosophers who regard holism with a mixture of fascination and suspicion. It shows whether the Duhem‐Quine Thesis true and it supports meaning holism if it is true. The rational revisability of statements has loomed large in discussions of holism. It is plausible that semantic values are assigned to expressions in such a way that canonical methods involving those expressions are always truth‐preserving. (shrink)

Growing evidence indicates that our higher rational capacities depend on social interaction—that only through engaging with others do we acquire the ability to evaluate beliefs as true or false, or to reflect on and evaluate the reasons that support our beliefs. Up to now, however, we have had little understanding of how this works. Here we argue that a uniquely human socio-linguistic phenomenon which we call ‘joint attention to mental content’ plays a key role. JAM is the ability to focus (...) together in conversation on the content of our mental states, such as beliefs and reasons. In such conversations it can be made clear that our attitudes to beliefs or reasons may conflict—that what I think is true, you might think is false, or that what I think is a good reason for believing something, you might think is a bad reason. We argue that through JAM, children discover that mental contents can be evaluated under various attitudes, and that this discovery transforms their mind-reading and reasoning abilities. (shrink)

We situate the debate on intentionality within the rise of cognitive neuroscience and argue that cognitive neuroscience can explain intentionality. We discuss the explanatory significance of ascribing intentionality to representations. At first, we focus on views that attempt to render such ascriptions naturalistic by construing them in a deflationary or merely pragmatic way. We then contrast these views with staunchly realist views that attempt to naturalize intentionality by developing theories of content for representations in terms of information and biological function. (...) We echo several other philosophers by arguing that these theories over-generalize unless they are constrained by a theory of the functional role of representational vehicles. This leads to a discussion of the functional roles of representations, and how representations might be realized in the brain. We argue that there’s work to be done to identify a distinctively mental kind of representation. We close by sketching a way forward for the project of naturalizing intentionality. This will not be achieved simply by ascribing the content of mental states to generic neural representations, but by identifying specific neural representations that explain the puzzling intentional properties of mental states.

In this paper, I show how theoretical discussion of recent research on the abilities of infants and young children to represent other agents’ beliefs has been shaped by a descriptivist conception of mental content, i.e., to the notion that the distal content of a mental representation is fixed by the core body of knowledge that is associated with that mental representation. I also show how alternative conceptions of mental content—and in particular Ruth Millikan’s teleosemantic approach—make it possible to endorse the (...) view that infants have the ability to track beliefs by as early as 6 months while failing to understand some of the ways in which beliefs combine with each other and with other mental states in contributing to inferences and actions. In articulating this view, I will draw upon Millikan’s recently developed notion of ‘unicepts’. Unicepts, according to Millikan, are the basic representational vehicles that underpin our abilities to identify objects, properties, relations and kinds. When applied to research on mindreading in infancy and early childhood, Millikan’s approach generates fruitful new questions about the development of belief reasoning, and about the functions of belief reasoning in infancy and at different stages of childhood.

The Representational Theory of the Mind allows for psychological explanations couched in terms of the contents of propositional attitudes. Propositional attitudes themselves are taken to be relations to mental representations. These representations (partially) determine the contents of the attitudes in which they figure. Thus, Representationalism owes an explanation of the contents of mental representations. This essay constitutes an atomistic theory of the content of formally or syntactically simple mental representation, proposing that the content of such a representation is determined by (...) the intersection of the representation's correlational and control properties. The theory is distinguished from standard information-based accounts of mental content in allowing that the relevant correlations be contingent while insisting on an efferent aspect to mental content. The theory on offer allows for a natural explanation of misrepresentation, finds a niche for the notion of narrow content, welcomes radical first person fallibility with respect to questions of content, admits of mental ambiguity and recognizes that the future of a psychological agent is a factor in determining the content of the agent's present psychological states.

The traditional understanding of analyticity in terms of concept containment is revisited, but with a concept explicitly understood as a certain kind of mental representation and containment being read correspondingly literally. The resulting conception of analyticity avoids much of the vagueness associated with attempts to explicate analyticity in terms of synonymy by moving the locus of discussion from the philosophy of language to the philosophy of mind. The account provided here illustrates some interesting features of representations and explains, at least (...) in part, the special epistemic status of analytic judgments. (shrink)

The truth-condition theory of meaning is, naturally, thought of an as explanatory theory whose explananda are the meaning facts. But there are at least two deductive arguments that purport to establish the truth of the theory irrespective of its explanatory virtues. This paper examines those arguments and concludes that they succeed.

. When I have a conscious experience of the sky, there is a bluish way it is like for me to have that experience. We may distinguish two aspects of this "bluish way it is like for me": the bluish aspect and the for-me aspect. Let us call the bluish aspect of the experience its qualitative character and the for-me aspect its subjective character . What is this elusive for-me-ness, or subjective character , of conscious experience? In this paper, I (...) examine six different attempts to account for subjective character in terms of the functional and representational properties of conscious experiences. After arguing against the first five, I defend the sixth. (shrink)

One of the most enduring elements of Davidson’s legacy is the idea that intentionality is inherently normative. The normativity of intentionality means different things to different people and in different contexts, however. A subsidiary goal of this paper is to get clear on the sense in which Davidson means the thesis that intentionality is inherently normative. The central goal of the paper is to consider whether the thesis is true, in light of recent work on intentionality that insists on an (...) intimate connection between intentionality and phenomenal consciousness. According to several recent authors, there is a kind of intentionality – “phenomenal intentionality” – that is fully constituted by the phenomenal character of conscious experiences. I will argue that although Davidson’s thesis, when correctly understood, is compelling for most intentionality, it is false of phenomenal intentionality. I start, in §1, with an explication of the notion of phenomenal intentionality; in §2, I elucidate Davidson’s thesis and his case for it; in §3, I argue that the case does not extend to phenomenal intentionality; I close, in §4, with some objections and replies.

This Article is a review of Barry Smith and Ernest Lepore's "Oxford Handbook of Philosophy of Language".

Dummett's case against platonism rests on arguments concerning the acquisition and manifestation of knowledge of meaning. Dummett's arguments are here criticized from a viewpoint less Davidsonian than Chomskian. Dummett's case against formalism is obscure because in its prescriptive considerations are not clearly separated from descriptive. Dummett's implicit value judgments are here made explicit and questioned. ?Combat Revisionism!? Chairman Mao.

Inferential Role Semantics is often criticized for being incompatible with the platitude that words of different speakers can mean the same thing. While many assume that this platitude can be accommodated by understanding sameness of meaning in terms of similarity of meaning, no worked out proposal has ever been produced for Inferential Role Semantics. I rectify this important omission by giving a detailed structural account of meaning similarity in terms of graph theory. I go on to argue that this account (...) has a number of attractive features, prominent among them that it makes sameness of meaning probabilistically determine co-reference. (shrink)

First, I argue that the narrow content of a thought cannot be identical with the linguistic meaning of the sentence used to express it. Secondly, I argue that the distinction between narrow content and linguistic meaning is not fatal to content-dualism. Thirdly I argue for the view that the proposition contributed by the clause prefixed by "that" is an interpretation of the believer's thought. Finally, I use this insight to provide an individualist account of Burge's thought-experiments such that recognition that (...) the truth-conditions of belief-ascriptions include aspects of the believer's environment does not entail that those environmental aspects are thereby parts of the contents of the person's thoughts.

Fictionalism has recently returned as a standard response to ontologically problematic domains. This article assesses moral fictionalism. It argues (i) that a correct understanding of the dialectical situation in contemporary metaethics shows that fictionalism is only an interesting new alternative if it can provide a new account of normative content: what is it that I am thinking or saying when I think or say that I ought to do something; and (ii) that fictionalism, qua fictionalism, does not provide us with (...) any new resources for providing such an account.

Despite its centrality in the philosophy of cognitive science, there has been little prior philosophical work engaging with the notion of representation in contemporary NLP practice. This paper attempts to fill that lacuna: drawing on ideas from cognitive science, I introduce a framework for evaluating the representational claims made about components of neural NLP models, proposing three criteria with which to evaluate whether a component of a model represents a property and operationalising these criteria using probing classifiers, a popular analysis (...) technique in NLP (and deep learning more broadly). The project of operationalising a philosophically-informed notion of representation should be of interest to both philosophers of science and NLP practitioners. It affords philosophers a novel testing-ground for claims about the nature of representation, and helps NLPers organise the large literature on probing experiments, suggesting novel avenues for empirical research.

In this paper, I propose a new way of understanding the space of possibilities in the field of mental content. The resulting map assigns separate locations to theories of content that have generally been lumped together on the more traditional map. Conversely, it clusters together some theories of content that have typically been regarded as occupying opposite poles. I make my points concrete by developing a taxonomy of theories of mental content, but the main points of the paper concern not (...) merely how to classify, but how to understand, the theories. Also, though the paper takes theories of mental content as a case study, much of the discussion is applicable to theories of other phenomena. To a first approximation, the difference between the traditional and the proposed taxonomies turns on whether we classify theories of content by, on the one hand, their implications for a non-redundant supervenience base for content facts (i.e., for facts about what contents thoughts have) or, on the other, by their constitutive accounts of content. By a "constitutive account," I mean the kind of elucidation of the nature of a phenomenon that theorists have tried to give for, for example, knowledge, justice, personal identity, consciousness, convention, heat, and limit. The tendency to taxonomize by supervenience base is encouraged, I suggest, by a failure to keep clearly in view a distinction between constitutive and modal determination. Many philosophers would accept that a constitutive account cannot be captured in purely modal terms. Giving a constitutive account is not the same as specifying modally necessary and sufficient conditions. Nevertheless, philosophers often try to cash constitutive claims in modal terms. A case in point is that theories of content tend to be conceptualized in terms of the theories' implications for a supervenience base for content facts. My thesis goes beyond the by-now somewhat familiar proposition that not all modal determinants of a phenomenon are constitutive determinants. One who has taken that point on board might nevertheless conceive of a philosophical account as an attempt to specify constitutive determinants of the target phenomenon that make up a non-redundant supervenience base for the phenomenon. Shoehorning a philosophical account into this form leaves out elements that are modally redundant, but may be explanatorily or ontologically significant. For example, when a constitutive account has multiple levels, the different levels will typically be modally redundant. Formulating the account as a specification of a supervenience base of constitutive determinants will therefore flatten the account into a single level. Many of my arguments can be illustrated by considering the place of normativity in the theory of content. The new taxonomy gives a distinct niche to normative theories of content - theories that explain a thought's having a certain content at least in part in terms of the obtaining of normative facts. By contrast, on a traditional map, normative theories are invisible as such because normative facts supervene on non-normative ones. (shrink)

In this paper I argue that defeasible inferences are occasion-sensitive: the inferential connections of a given claim depend on features of the circumstances surrounding the occasion of inference. More specifically, it is an occasion-sensitive matter which possible defeaters have to be considered explicitly by the premises of an inference and which possible defeaters may remain unconsidered, without making the inference enthymematic. As a result, a largely unexplored form of occasion-sensitivity arises in inferentialist theories of content that appeal to defeasible inferences.

Whether or not qualia are ways things seem, the view that qualia have the properties typically attributed to them is unjustified. Ways things seem do not have many of the properties commonly attributed to them. For example, inverted ways things seem are impossible. If ways things seem do not have the features commonly attributed to them, and qualia do have those same features, this looks like good reason to distinguish the two. But if your reasons for believing that qualia have (...) the features are epistemically on a par with reasons for believing that ways things seem have the features, and you know that ways things seem do not have the features, then those reasons cannot justify your belief that qualia have the features. I argue that the reasons are epistemically on a par in this way. (shrink)

Is it possible for there to be facts about reality with a logical structure that is in principle unrepresentable by us? I outline the main motivations for thinking that this question should receive a positive answer. I then argue that, upon inspection, the view that such structurally ineffable facts are possible is self-defeating and thus incoherent. My argument is based on considerations about the fundamental role that the purely formal concept of an object plays in our propositional representations and its (...) intimate connection with subject-predicate structure.

The aim of this article is to argue against the real possibility of languages without subject‐predicate structure, so‐called feature‐placing languages. They were first introduced by Strawson (1959/1990), later given formal expression through Quine's Predicate Functor Logic (Quine, 1960, Quine, 1971/Quine, 1976, Quine, 1992), and further elaboration in (Hawthorne & Cortens, 1995). I argue that, on the presumption that feature‐placing languages are not mere notational variants on first‐order languages, the idea of such languages is incoherent. The argument for this view rests (...) on two highly plausible views about the conditions for the possibility of sentential meaning in natural languages. If accepted, these two views jointly imply that the sentences of feature‐placing languages lack sufficient internal structure to meet the conditions for sentential meaning. Feature‐placing languages cannot then count as genuine languages. (shrink)

This paper deals with the problem of understanding semiosis and meaning in cognitive systems. To this aim we argue for a unified two-factor account according to which both external and internal information are non-independent aspects of meaning, thus contributing as a whole in determining its nature. To overcome the difficulties stemming from this approach we put forward a theoretical scheme based on the definition of a suitable representation space endowed with a set of transformations, and we show how it can (...) be implemented, in the case of a single agent, by a neural network architecture. Numerical experiments conducted on different instances of the latter show that similar representations are developed as a consequence of the fact that these instances are facing a similar semantic task. This allows to model social and environmental influences through a system of interacting agents, each described by a specific implementation of this model architecture. (shrink)

This paper identifies and criticizes a line of reasoning that has played a substantial role in the widespread rejection of the view that Fodor has dubbed “Concept Atomism”. The line of reasoning is not only fallacious, but its application in the present case rests on a misconception about the explanatory potential of Concept Atomism. This diagnosis suggests the possibility of a new polemical strategy in support of Concept Atomism. The new strategy is more comprehensive than that which defenders of the (...) view, namely Fodor, have employed. (shrink)

This paper explores the psychological analogues of a cluster of arguments that have played an important role in motivating a now widespread, reference-based approach in philosophy of language. What I will call the psychological analogues of Kripke-style arguments provide a substantial motivation for a reference-based approach to concepts. Insofar as such an approach is rarely given serious consideration, the availability of these arguments suggests the need for a rethinking of some foundational assumptions in philosophy of mind and other branches of (...) the cognitive sciences.

According to so-called epistemic theories of conditionals, the assertability/acceptability/acceptance of a conditional requires the existence of an epistemically significant relation between the conditional’s antecedent and its consequent. This paper points to some linguistic data that our current best theories of the foregoing type appear unable to explain. Further, it presents a new theory of the same type that does not have that shortcoming. The theory is then defended against some seemingly obvious objections.

Are there such things as moral truths? How do we know what we should do? And does it matter? Constructivism states that moral truths are neither invented nor discovered, but rather are constructed by rational agents in order to solve practical problems. While constructivism has become the focus of many philosophical debates in normative ethics, meta-ethics and action theory, its importance is still to be fully appreciated. These new essays written by leading scholars define and assess this new approach in (...) ethics, addressing such questions as the nature of constructivism, how constructivism improves our understanding of moral obligations, how it accounts for the development of normative practices, whether moral truths change over time, and many other topics. The volume will be valuable for advanced students and scholars of ethics and all who are interested in questions about the foundation of morality. (shrink)

Phenomenal intentionality is supposed to be a kind of directedness of the mind onto the world that is grounded in the conscious feel of mental life. This book of new essays explores a number of issues raised by the notion of phenomenal intentionality.

The notion of a "mental representation" is, arguably, in the first instance a theoretical construct of cognitive science. As such, it is a basic concept of the Computational Theory of Mind, according to which cognitive states and processes are constituted by the occurrence, transformation and storage (in the mind/brain) of information-bearing structures (representations) of one kind or another.

Qualia inversion thought experiments are ubiquitous in contemporary philosophy of mind. The most popular kind is one or another variant of Locke's hypothetical case of.

In this paper I begin to develop an account of the acquaintance that each of us has with our own conscious states and processes. The account is a speculative proposal about human mental architecture and specifically about the nature of the concepts via which we think in first personish ways about our qualia. In a certain sense my account is neutral between physicalist and dualist accounts of consciousness. As will be clear, a dualist could adopt the account I will offer (...) while maintaining that qualia themselves are non-physical properties. In this case the non-physical nature of qualia may play no role in accounting for the features of acquaintance. But although the account could be used by a dualist, its existence provides support for physicalism. (shrink)

Using conjunction as an example, I show a technical and philosophical problem when trying to conciliate the currently prevailing views on the meaning of logical connectives: the inferientialist (also called 'syntactic') one based on introduction and elimination rules, and the representationalist (also called 'semantic') one given through truth tables. Mostly I show that the widespread strategy of using the truth theoretical definition of logical consequence to collapse both definitions must be rejected by inferentialists. An important consequence of my argument is (...) that there are different notions of conjunction at play in standard first order logic, and that the technical and philosophical connections between them are far from well established.

This paper is intended to sketch the definition of a methodological tool -- the notion of a format of representation -- for the study of scientific theorising. One of its main assumption is that a philosophical study of theorising needs to pay attention to other types of units of analysis than the traditional ones, namely, theories and models approached in a logical and structural way, since scientific reasoning is always led on concrete representational devices and depends upon their specific properties. (...) The notion of a format is intended to characterise the differences between various types of representational devices, in terms of the inferences they enable cognitive agents to draw. (shrink)

John is currently thinking that the sun is bright. Consider his occurrent belief or judgement that the sun is bright. Its content is that the sun is bright. This is a truth- evaluable content (which shall be our main concern) because it is capable of being true or false. In virtue of what natural, scientifically accessible facts does John’s judgement have this content? To give the correct answer to that question, and to explain why John’s judgement and other contentful mental (...) states have the contents they do in virtue of such facts, would be to naturalize mental content.

This dissertation investigates the plausibility of metaethical relativism, or more specifically, what I call “moral truth-value relativism”: the idea that the truth of a moral statement or belief depends on who utters or has it, or who assesses it. According to the most prevalent variants of this view in philosophical literature – “standard relativism” – the truth-values are relative to people’s moralities, often understood as some subset of their affective or desirelike attitudes. Standard relativism has two main contenders: absolutism – (...) the view that the truth-values of moral statements and beliefs do not vary in that way – and non-cognitivism – the view that moral judgements do not have truth-values, since they express affective or desire-like attitudes rather than beliefs. Almost the entire dissertation concerns the plausibility of standard relativism in contrast to absolutism. Part 1 examines first the two main arguments for standard relativism: that it accounts for the connection between moral judgements and motivation (chapter 2), and for the prevalence of diversity of moral opinion (chapter 3). Then the most common objection is considered: that it is inconsistent with the existence of genuine moral disagreements (chapter 4). I argue that these arguments are inconclusive. Both relativism and absolutism can account for the features discussed. Part 2 focuses on the fact that different people have different strongly held intuitions about the relative or absolute nature of morality. I argue that given a common methodological approach in philosophy and metaethics, which takes such intuitions as evidence of correct analyses, this difference in intuitions suggests that neither a relativist nor absolutist analysis can be correct for everyone’s moral judgements. I argue that this result holds both given semantic internalism (chapter 6) and given semantic externalism (chapter 7). To get one single analysis of everyone’s moral judgements we would have to abandon the intuitionbased methodology. In chapter 8, however, I argue that we can maintain this methodology if we accept analysis pluralism, the view that different analyses hold for different people’s moral judgements. (shrink)

This thesis studies the role of conceptual content in inference and reasoning. The first two chapters offer a theoretical and historical overview of the relation between inference and meaning in philosophy and psychology. In particular, a critical analysis of the formality thesis, i.e., the idea that rational inference is a rule-based and topic-neutral mechanism, is advanced. The origins of this idea in logic and its influence in philosophy and cognitive psychology are discussed. Chapter 3 consists of an analysis of the (...) relationship between inference and representation. It is argued that inference has to be studied from a pluralistic per- spective due to its dependence on different formats of representing information. The following four chapters apply conceptual spaces, a formal theory of concepts within cognitive semantics, to three concept-based inference-types. First, an explication of Sellars notion of material inference is advanced. Later, the model is extended to account for nonmonotonic inference by studying the role expectations in reasoning. Finally, a conceptual space-model of category-based induction is presented. This model predicts most of the empirical properties of this psychological phenomenon and subsumes some of the previous theories in psychology. It is stated that the explanatory fruitfulness of this new approach is evidence for the failure of the formality thesis and calls for a unified model of rational inference that puts semantics at center stage. The last chapter of the thesis discusses how inference and concepts interact in scientific reasoning, which makes constant use of hybrid symbolic structures for representing conceptual information. Stephen Toulmin’s notions of method of representation and inferential technique are developed and applied in a case study about the emergence of the notion of instantaneous speed during the passage from geometrical physics to analytical mechanics. It is claimed that this analysis provides support to the pluralistic perspective for theorizing about reasoning. (shrink)
