The main question of metasemantics, or foundational semantics, is why an expression token has the meaning (semantic value) that it in fact has. In his reading of Ludwig Wittgenstein’s later work, Saul Kripke presented a skeptical challenge that threatened to make the foundational question unanswerable. My first contention in this paper is that the skeptical challenge indeed poses an insoluble paradox, but only for a certain kind of metasemantic theory, against which the challenge effectively works as a reductio ad absurdum (...) argument. My second contention is that as a result of rejecting the theory which entails a paradoxical outcome, we will see that the foundational question essentially involves a temporal dimension. After arguing that the skeptical challenge gives us a strong reason to adopt a historical view of meaning, I shall further argue against certain authors who claim that meanings not only have histories but futures as well, or that the meaning of a word may change retroactively in time as a consequence of counterfactual change in its future use. The major aim of the paper is thus to bring together the arguably interrelated debates about the skeptical challenge and temporal externalism in philosophy of language. (shrink)

The tenth proposition of Spinoza’s Ethics reads: ‘Each attribute of substance must be conceived through itself.’ Developing and defending the argument for this single proposition, it turns out, is vital to Spinoza’s philosophical project. Indeed, it’s virtually impossible to overstate its importance. Spinoza and his interpreters have used EIp10 to prove central claims in his metaphysics and philosophy of mind (i.e., substance monism, mind-body parallelism, mind-body identity, and finite subject individuation). It’s crucial for making sense of his epistemology (i.e., Spinoza’s (...) account of knowledge and response to skepticism) and in resolving puzzles within the Ethics (i.e., explaining human ignorance of all but two attributes). Even those who do not attribute some of the above claims to Spinoza need EIp10 to defend much of what they believe about Spinoza’s system. This paper locates a previously unnoticed argument for this proposition in Spinoza’s Short Treatise on God, Man, and His Well Being. There, Spinoza shows himself concerned with a powerful and underappreciated form of philosophical skepticism, one with surprising echoes in the work of his contemporary Leibniz as well as in the later Wittgenstein. Spinoza’s introduction of E1p10 in the Ethics circumvents this form of skepticism, solving the problem the Short Treatise envisions while also explaining that text’s argument’s absence from the explicit justificatory structure of the Ethics.

John Searle claims that intentional states require a set of non-intentional background capacities in order to function. He insists that this 'Background' should be construed naturalistically, in terms of the causal properties of biological brains. This paper examines the relationship between Searle's conception of the Background and his commitment to biological naturalism. It is first observed that the arguments Searle ventures in support of the Background's existence do not entail a naturalistic interpretation. Searle's claim that external realism is part of (...) the Background is then addressed. It is shown that this claim implies an implicit understanding of reality, which is presupposed by the intelligibility of any objective, scientific description. As a consequence, Searle's account of the Background's role is incompatible with his insistence that it can be comprehensively characterized in terms of biological capacities. I conclude by showing that, if the tension is resolved by rejecting biological naturalism, Searle's position takes a substantial step in the direction of Heideggerian phenomenology, a move Searle has emphatically resisted in his various exchanges with Hubert Dreyfus.

We evaluate the richness of the child’s input in semantics and its relation to the hypothesis space available to the child. Our case study is the acquisition of the universal quantifier every. We report two main findings regarding the acquisition of every on the basis of a corpus study of child-directed and child-ambient speech. Our first finding is that the input in semantics is rich enough to systematically eliminate instances of the subset problem of language acquisition: overly general hypotheses about (...) the meaning of every can violate pragmatic constraints, making such hypotheses incompatible with the child’s input. Our second finding is that the semantic input is too poor to eliminate instances of what we refer to as the superset problem, the mirror image of the subset problem. We argue that at least some overly specific hypotheses about the meaning of every are compatible with the child’s input, suggesting either that those hypotheses are not made available by UG or that non-trivial inductive biases are involved in children’s acquisition of every.

This article aims to defend the need to recognize the independent role of those cognitive abilities on whose behalf linguistic meaning is introduced from the proper institution of language. I call this capacity “private pattern recognition” (PPR) and argue that it plays an essential part not just in the instauration of linguistic meaning but also in other relevant cognitive phenomena such as artistic creation and understanding. Moreover, it is precisely the failure to separate both aspects that gives rise to important (...) perplexities associated with the underdetermination of meaning. The first part of the article makes a case for this thesis and addresses its compatibility with Wittgenstein's private language argument. It then focuses on the example of art to illustrate the differing roles of private pattern recognition and shared linguistic meaning. The second part of the article focuses on the paradox of resemblance (RP). It (i) considers the difficulties of Williamson's response, (ii) illustrates how they instead support the current thesis, (iii) attempts to delineate how the role of meaning should be understood, and (iv) briefly revisits the rule‐following paradox (RFP).

The section we have examined is a persuasive and sustained demolition of the realist strategy of deriving an invariable concomitance between the existenthood of the world and the system of validation (a system accepted by both parties as being the regulator of epistemic activity). This leaves the Advaitin with an absence of invariable concomitance. This is where the Advaitin wants to be. On his view, the absence of this concomitant dependence of the system of validation on an ‘existent’ world points (...) to the possibility that the cognized world is not that independent world which Nyāya takes to be the determinate reality. If that world is not philosophically proven to be so independent, then there is at least aprima facie case for the Advaitic soteriological claim that it is Brahman alone which is ultimately real, even though the commonly cognized world allows of coherent epistemic activity. It is fair to say that such a view is established by the failure of the opponent to prove invariable concomitance between inquiry, validation and an independent world. It is the inability of the opposing view to prove a metaphysical claim which itself points to the nature of the Advaitic position; the position, that is, which suspends the need to make an ontic commitment to the extrinsic world as a determinate reality. Whether the critique of the Nyāya concept ofsattā takes us to the refutation of the Nyāya concept of a determinate world (and whether the Advaitic rejection ofsattā is of a piece with the concept of an ‘indeterminate’ world) is another issue, dealt with in detail by Śrī Har $$\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\cdot}$}}{s} $$ a elsewhere in his book, but beyond the purview of this paper.

This article provides a survey of Wittgenstein’s remarks in which he discusses various kinds of technology. I argue that throughout his career, his use of technological examples displays a thematic unity: technologies are invoked in order to illustrate a certain mechanical conception of the mind. I trace how his use of such examples evolved as his views on the mind and on meaning changed. I also discuss an important and somewhat radical anti-mechanistic strain in his later thought and suggest that (...) Wittgenstein’s attitude to mechanistic explanations in psychology was ultimately quite ambivalent. (shrink)

According to the quotational theory of meaning ascriptions, sentences like “‘Bruder means brother” are abbreviated synonymy claims, such as “‘Bruder means the same as ‘brother’”. After discussing a problem with Harman’s version of the quotational theory, I present an amended version defended by Field. Then, I address Field’s responses to two arguments against the theory that revolve around translation and the understanding of foreign expressions. Afterwards, I formulate two original arguments against both Harman’s and Field’s versions of the theory. One (...) of them targets the hyperintensionality of quotations and the other raises a problem pertaining to variant spellings of words. (shrink)

This paper draws a distinction between the existential quantifier and the symbol ‘∃’ used to express it, on the one hand, and existence and ‘exists’, on the other. It argues that some popular arguments in metaphysics, including arguments against vague existence and arguments against deflationary metaontology (which views ontological disputes as lacking substance), are guilty of fudging this distinction. The paper draws some lessons for metaphysical debate about existence and highlights some heretofore ignored and attractive positions in logical space.

ABSTRACTThis paper provides a naturalistic account of inference. We posit that the core of inference is constituted by bare inferential transitions, transitions between discursive mental representations guided by rules built into the architecture of cognitive systems. In further developing the concept of BITs, we provide an account of what Boghossian [2014] calls ‘taking’—that is, the appreciation of the rule that guides an inferential transition. We argue that BITs are sufficient for implicit taking, and then, to analyse explicit taking, we posit (...) rich inferential transitions, which are transitions that the subject is disposed to endorse.

Today, the notion of identity is usually linked with ethical-political discussions like multiculturalism, gender or sexual diversity, recognition of plurality, etc. Nevertheless, the flourishing of this vision that interprets “identity” mainly in its plural form (as “identities”) contrasts sharply with the sense that “identity” has had during most of the history of philosophy (in which identity was understood in connection with “unity” or “selfsameness”, not with “diversity” or “otherness”). In order to explain the passage from one notion of identity to (...) the other (a passage mainly made in the last third of the 20th century), we will focus on the reflections made by Ludwig Wittgenstein towards the middle of that century. Our contention is that these reflections open the way to a more plural understanding of human identity, against the many interpreters of Wittgenstein that defend the opposite: that he offered a strong notion of common human identity in his writings, a notion based on the idea of “human nature”. In order to sustain our thesis, we will have to give an interpretation of some key terms of Wittgenstein’s philosophy (like “forms of life” or “natural history”) from a pluralistic point of view; this is the only way of understanding to what extent he is a predecessor of contemporary discussions about plural identities.

How to model meaning processes (semiosis) in artificial semiotic systems? Once all computer simulation becomes tantamount to theoretical simulation, involving epistemological metaphors of world versions, the selection and choice of models will dramatically compromise the nature of all work involving simulation. According to the pragmatic Peircean based approach, semiosis is an interpreter-dependent process that cannot be dissociated from the notion of a situated (and actively distributed) communicational agent. Our approach centers on the consideration of relevant properties and aspects of Peirce’s (...) pragmatic concept of semiotics. Upon developing this approach, we have no pretensions of our being able to present an exhaustive analysis of the differences between Peirce and other theoretical positions. Nevertheless, our contribution will serve to demonstrate how theorists contribute toward revealing certain fundamental ‘semiotic constraints’ that will be of interest and importance. (shrink)

Social and political concepts are indispensable yet historically and culturally variable in a way that poses a challenge: how can we reconcile confident commitment to them with awareness of their contingency? In this article, we argue that available responses to this problem—Foundationalism, Ironism, and Right Wittgensteinianism—are unsatisfactory. Instead, we draw on the work of Bernard Williams to tease out and develop a Left Wittgensteinian response. In present-day pluralistic and historically self-conscious societies, mere confidence in our concepts is not enough. For (...) modern individuals who are ineluctably aware of conceptual change, engaged concept-use requires reasonable confidence, and in the absence of rational foundations, the possibility of reasonable confidence is tied to the possibility of critically discriminating between conceptual practices worth endorsing and those worth rejecting. We show that Left Wittgensteinianism offers such a basis for critical discrimination through point-based explanations of conceptual practices which relate them to the needs of concept-users. We end by considering how Left Wittgensteinianism guides our understanding of how conceptual practices can be revised in the face of new needs. (shrink)

Dog whistling—speech that seems ordinary but sends a hidden, often derogatory message to a subset of the audience—is troubling not just for our political ideals, but also for our theories of communication. On the one hand, it seems possible to dog whistle unintentionally, merely by uttering certain expressions. On the other hand, the intention is typically assumed or even inferred from the act, and perhaps for good reason, for dog whistles seem misleading by design, not just by chance. In this (...) paper, I argue that, to understand when and why it’s possible to dog-whistle unintentionally (and indeed, intentionally), we’ll need to recognize the structure of our linguistic practices. For dog whistles and for covertly coded speech more generally, this structure is a pair of practices, one shared by all competent speakers and the other known only to some, but deployable in the same contexts. In trying to identify these enabling conditions, we’ll discover what existing theories of communicated content overlook by focusing on particular utterances in isolation, or on individual speakers’ mental states. The remedy, I argue, lies in attending to the ways in which what is said is shaped by the temporally extended, socio-politically structured linguistic practices that utterances instantiate. (shrink)

Given (1) Wittgensteins externalist analysis of the distinction between following a rule and behaving in accordance with a rule, (2) prima facie connections between rule-following and psychological capacities, and (3) pragmatic issues about training, it follows that most, even all, future artificially intelligent computers and robots will not use language, possess concepts, or reason. This argument suggests that AIs traditional aim of building machines with minds, exemplified in current work on cognitive robotics, is in need of substantial revision.

The two main challenges of the theory of conceptual content presented by Robert Brandom in Making It Explicit are to account for a referential dimension of conceptual content and to account for the objectivity of conceptual norms. Brandom tries to meet both these challenges in chapter 8 of his book. I argue that the accounts presented there can only be understood if seen against the background of Brandom's theory of communication developed in chapter 7. This theory is motivated by the (...) well-known problem that semantic holism threatens the possibility of communication because it has the consequence that words mean different things in different mouths. Brandom offers a solution to this problem in terms of what he calls recurrence commitments. I show that chapter 8 of Making It Explicit should be understood as arguing that a practice that includes acknowledging interpersonal recurrence commitments institutes both conceptual contents with a referential dimension and objective conceptual norms. I close by raising the objection that Brandom's argument can only show that conceptual norms are communally shared and not that they are objective. I propose an emendation of this argument, having recourse to a practice Brandom refers to as rational rectification in his new book Between Saying and Doing. (shrink)

Locke’s claim that the primary signification of (most) words is an idea, or complex of ideas, has received different interpretations. I support the majority view that Locke’s notion of primary signification can be construed in terms of linguistic meaning. But this reading has been seen as making Locke’s account vulnerable to various criticisms, of which I consider two. First, it appears to make the account vulnerable to the charge that an idea cannot play the role that a word meaning should (...) play. I argue that the role Locke actually gives to signified ideas is not susceptible to this criticism. Second, it appears to make Locke guilty of at least some degree of semantic idealism. I argue that Locke is not guilty of this and that he makes a proper distinction between the non-referential relation that holds between a word and its primary signification and the referential relation that holds between a word and things the word is used to speak about.

This paper discusses the relation between Crispin Wright’s alethic pluralism and my global expressivism. I argue that on many topics Wright’s own view counts as expressivism in my sense, but that truth itself is a striking exception. Unlike me, Wright never seems to countenance an expressivist account of truth, though the materials needed are available to him in his approaches to other topics.

ABSTRACT As a part of John Broome’s stated aim to establish a clear distinction between rationality and normativity, Broome suggests a novel definition of normativity as a property term that applies to persons. Since this construal of normativity diverges significantly from most prominent renderings of the concept within contemporary philosophical discussions, it merits critical scrutiny. In response to Broome, I thus examine the technical advantage of Broome’s approach, while also indicating some drawbacks of Broome’s novel conceptualization of ‘normative’ and ‘normativity’.

The noema is one of the most daring and controversial concept of the Husserlian theory of intentionality. It was first introduced by Husserl in 1912, within some research manuscripts, but was only fully developed in Ideen. In this paper I claim that the noema is an ambiguous notion, the result of a theoretical operation, the epoché, whose aim is contradictory. In an effort to keep open the epoché, and therefore maintain distance with respect to every transcendent object, Husserl is forced (...) to multiply intentional objects and complicate the notions of sense and noema. Given that, I propose to overcome the paradoxes of noema through the language of game theory. Game theory offers a very fruitful descriptive model that allows us to save the original Husserlian approach without the contradictions of the epoché. For this reason, I propose to re-interpret intentionality as social game, and the noema as Nash equilibrium. By replying to possible objections, I will show that this approach gives us many theoretical advantages. The general aim of the paper is a global reformulation of the phenomenalogical method.

This paper offers a new interpretation for Wittgenstein`s treatment of mathematical identities. As it is widely known, Wittgenstein`s mature philosophy of mathematics includes a general rejection of abstract objects. On the other hand, the traditional interpretation of mathematical identities involves precisely the idea of a single abstract object – usually a number –named by both sides of an equation.

The resemblance is plain to see between Kripke’s Wittgenstein introducing bizarre rules such as _quaddition_ (in illustrating the _sceptical paradox_ against theories of meaning) and Goodman’s introducing the equally bizarre _grue_ (in generating the _new riddle of induction_). But the two sorts of bizarre cases also differ in interesting respects. For those familiar with Goodman’s case, this similarity sparks a strong temptation to enlist to the meaning sceptic’s cause key elements of Goodman’s new riddle, which are missing from Kripke’s case. (...) In this essay, I characterize a natural way of doing just this, which targets dispositionalist solutions to the sceptical paradox. I also show that, despite initial appearances, this new objection to dispositionalism (the symmetry problem) is not nearly as worrisome as originally thought. The solution offered on behalf of semantic dispositionalists does require a trade-off, though, from the severe form of indeterminacy advanced by the meaning sceptic to a much milder thesis. (shrink)

Dispositionalist theories of mental content have been attacked on the grounds that they are incompatible with semantic holism. In this paper, I resist important worries of this variety, raised by Paul Boghossian. I argue that his objections can be avoided by a conceptual role version of dispositionalism, where the multifarious relationships between mental contents are grounded on the relationships between their corresponding, grounding dispositions.

Abstract: According to certain dispositional accounts of meaning, an agent's meaning is determined by the dispositions that an idealized version of this agent has in optimal conditions. We argue that such attempts cannot properly fix meaning. For even if there is a way to determine which features of an agent should be idealized without appealing to what the agent means, there is no non-circular way to determine how those features should be idealized. We sketch an alternative dispositional account that avoids (...) this problem, according to which an agent's meaning is determined by the dispositions that an abstract version of this agent has in optimal conditions.

Klein’s account of epistemic justification, infinitism, supplies a novel solution to the regress problem. We argue that concentrating on the normative aspect of justification exposes a number of unpalatable consequences for infinitism, all of which warrant rejecting the position. As an intermediary step, we develop a stronger version of the ‘finite minds’ objection.

Hayek's and Mises's argument for the impossibility of socialist planning is once again popular. Their case against socialism is predicated on an account of the nature of knowledge and social interaction. Hayek refined Mises's original argument by developing a philosophical anthropology which depicts individuals as tacitly knowledgeable rule-followers embedded in a 'spontaneous order' of systems of rules. Giddens, whose social theory is informed by his reading of Wittgenstein, has recently added his sociological support to Hayek's 'epistemological argument' against socialism. With (...) the aid of an interpretation of Wittgenstein which emphasizes his philosophy of praxis , I attempt to 'deconstruct' Giddens's and Hayek's 'picture' of tacit knowledge and rule-following on which their argument against socialism is predicated.

According to Herman Cappelen’s Austerity Framework, conceptual engineering doesn’t involve concepts, and barely involves engineering. I begin by raising two objections to the Austerity Framework as it stands: the framework cannot account for important normative aspects of conceptual engineering; and it doesn’t give us an adequate response to Strawson-style objections that conceptual engineering serves only to change the subject. I then supplement the Austerity Framework with an account of semantic normativity, which builds on the speaker/semantic meaning distinction, and show that (...) so-supplemented the Austerity Framework successfully overcomes the two objections. I tentatively conclude that semantic normativity should play a key role in how we understand conceptual engineering. (shrink)

A common view is that ceteris paribus clauses render lawlike statements vacuous, unless such clauses can be explicitly reformulated as antecedents of ?real? laws that face no counterinstances. But such reformulations are rare; and they are not, we argue, to be expected in general. So we defend an alternative sufficient condition for the non-vacuity of ceteris paribus laws: roughly, any counterinstance of the law must be independently explicable, in a sense we make explicit. Ceteris paribus laws will carry a plethora (...) of explanatory commitments; and claims that such commitments are satisfied will be as (dis) confirmable as other empirical claims. (shrink)

The aim of this paper is to present the ontic approach to the normativity of cognitive functions and mechanisms, which is directly related to the understanding of biological normativity in terms of normative mechanisms. This approach assumes the hypothesis that cognitive processes contain a certain normative component independent of external attributions and researchers’ beliefs. This component consists of specific cognitive mechanisms, which I call normative. I argue that a mechanism is normative when it constitutes given actions or behaviors of a (...) system. More precisely, it means that, on the one hand, it is their constitutive cause, and on the other hand, it determines a certain field of possibilities from which the system, guided by its own goals, preferences, environmental constraints, etc., chooses the appropriate action or behavior according to a given situation. The background for the analyses presented here is the predictive processing framework, in which it can be shown that at least some of the predictive mechanisms are in fact normative mechanisms. I refer here to the existence of a motivational relation which determines the normative dependence of the agent’s actions due to specific predictions and environmental constraints. (shrink)

In its most general form, the issue of intentionality takes the following shape: How can something be about something else? In basic cases, this relation is one between a subjective occurrence and a state of affairs, allowing the problem of intentionality to be articulated in this manner: What makes it the case that a subjective occurrence has the capacity to be about something external to it? The views of John McDowell on intentionality form the focus of this article. They are (...) examined through the notion of content and via the later Wittgenstein's standpoint on content and intentionality. The main objective is to reach a conspicuous perspective of McDowell's stance on intentionality in order to uncover its presuppositions. This leads to the identification of a pivotal point of tension in McDowell's philosophical commitments, in particular the extent to which he can legitimately claim to be a quietist. (shrink)

Peter Winch’s 1958 book The Idea of a Social Science contains two distinguishable sets of theses, one set bearing on the individual-level understanding of human beings, the other on the society-level understanding of the regularities and institutions to which human beings give rise. The first set of claims is persuasive and significant but the second is a mixed bunch: none is well established and only some are sound.

This paper offers a definition of social holism that makes the doctrine non-trivial but possibly true. According to that definition, the social holist maintains that people depend non-causally on interaction with one another for possession of the capacity to think; the thesis is meant to be a contingent truth but one, like physicalism, that is plausible in the light of some a priori argument and some plausible empirical assumptions. The paper also sketches an argument in support of social holism, which (...) connects with themes in a number of traditions, philosophical and sociological. The key idea is that people depend on socially shared dispositions and responses for the ability to identify - identify fallibly - the properties and other entities that they consider in each individual has to the course of thinking.

John Broome’s Rationality Through Reasoning is a trail-blazing study of the nature of rationality, the nature of reasoning and the connection between the two. But it may be somewhat misleading in two respects. First, his theory of reasoning is consistent with the meta-propositional view that he rejects; it develops a broadly similar theory but in much greater detail. And while his discussion of rule-following helps to explain the role of rules in reasoning, it does not constitute a response to the (...) classic problem associated with Wittgenstein and Kripke.

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 mental realm seems different to the physical realm; the mental is thought to be dependent on, yet distinct from the physical. But how, exactly, are the two realms supposed to be different, and what, exactly, creates the seemingly insurmountable juxtaposition between the mental and the physical? This review identifies and discusses five marks of the mental, features that set characteristically mental phenomena apart from the characteristically physical phenomena. These five marks (intentionality, consciousness, free will, teleology, and normativity) are not (...) presented as a set of features that define mentality. Rather, each of them is something we seem to associate with phenomena we consider mental, and each of them seems to be in tension with the physical view of reality in its own particular way. It is thus suggested how there is no single mind-body problem, but a set of distinct but interconnected problems. Each of these separate problems is analyzed, and their differences, similarities and connections are identified. This provides a useful basis for future theoretical work on psychology and philosophy of mind, that until now has too often suffered from unclarities, inadequacies, and conflations. (shrink)

Recent decades are marked by the upswing of the use of the term “normativity“ not only in philosophical discussions, but increasingly also within reports of empirical scientists. This may invoke the question how far these developments overlap and in how far they go past each other. A significant overlap might lead to an interesting coalescence of the two approaches to norms, which may provide for a ”naturalization” of some philosophical speculations about normativity, putting them on a firmer foundation, while offering (...) the empirical scientists some new impulses for directing their research. In this paper I give an overview of some recent empirical results concerning human normativity and I point out a certain philosophical tradition, rooted especially in the works of Wittgenstein, Sellars and Brandom, which treats normativity so that it becomes more or less compatible with these results.

This essay is concerned with Indian Yogācāra philosophers’ treatment of the problem of other minds in the face of a threatened collapse into solipsism suggested by Vasubandhu’s epistemological argument for idealism.

It is a platitude that when we reason, we often take things for granted, sometimes even justifiably so. The chemist might reason from the fact that a substance turns litmus paper red to that substance being an acid. In so doing, they take for granted, reasonably enough, that this test for acidity is valid. We ordinarily reason from things looking a certain way to their being that way. We take for granted, reasonably enough, that things are as they look Although (...) it is a platitude that we often take things for granted when we reason—whether justifiably or not—one might think that we do not have to. In fact, it is a natural expectation that were we not pressed by time, lack of energy or focus, we could always in principle make explicit in the form of premises every single presupposition we make in the course of our reasoning. In other words, it is natural to expect it to be true that presuppositionless reasoning is possible. In this essay, I argue that it is false: presuppositionless reasoning is impossible. Indeed, I think this is one of the lessons of a long-standing paradox about inference and reasoning known as Lewis Carroll’s (1985) regress of the premises. Many philosophers agree that Carroll’s regress teaches us something foundational about reasoning. I part ways about what it is that it teaches us. What it teaches us is that the structure of reasoning is constitutively presuppositional. (shrink)

This essay argues that the main lesson of Lewis Carroll's Regress is that arguments are constitutively presuppositional.

Physicalism about colour is the thesis that colours are identical with response-independent, physical properties of objects. I endorse the Argument from Structure against Physicalism about colour. The argument states that Physicalism cannot accommodate certain obvious facts about colour structure: for instance, that red is a unitary colour while purple is a binary colour, and that blue resembles purple more than green. I provide a detailed formulation of the argument. According to the most popular response to the argument, the Physicalist can (...) accommodate colour structure by explaining it in terms of colour experience. I argue that this response fails. Along the way, I examine other interesting issues in the philosophy of colour and colour perception, for instance the relational structure of colour experience and the description theory of how colour names refer.

Resumen: En este artículo se aborda el argumento elaborado por Ludwig Wittgenstein en las Philosophische Untersuchungen acerca de la imposibilidad de un lenguaje privado. El objetivo de dicho abordaje reside en la presentación de una serie de argumentos, reconstruidos a partir de la pragmática trascendental del lenguaje, que demuestran también de una manera acabada la imposibilidad de concebir un lenguaje semejante. La importancia de los razonamientos de la pragmática trascendental consiste en que explicitan una forma de tener en cuenta el (...) propio proceso argumentativo que está ausente en los planteos de Wittgenstein. Así, luego de presentar la importancia y las particularidades del argumento de Wittgenstein se desarrolla la interpretación que es posible esgrimir desde la pragmática, así como una distinción que debe establecerse cuando se abordan cuestiones referidas al lenguaje. Por último se extraen algunas conclusiones.: This article addresses the argument developed by Ludwig Wittgenstein in Philosophische Untersuchungen about the impossibility of a private language. The objective of this approach is to present a series of arguments, reconstructed from the point of view of transcendental pragmatics of language, which also demonstrate in a finished way the impossibility of such a language. The importance of the transcendental pragmatics reasonings is that they explicitly state a way of considering the very process of argumentation that is absent in Wittgenstein’s statements. After presenting the importance and particularities of Wittgenstein’s argument, the interpretation that can be employed from pragmatics is developed, as well as a distinction that must be made when dealing with issues related to language. Finally, some conclusions are drawn. (shrink)

In this paper, we would like to discuss Wittgenstein’s critique of the idea that a person’s experiences are necessarily private, and these experiences can only be expressible in a private language. Taking a clue from Wittgenstein, we intend to say that the person’s experiences though private, can also be known by others. In the following sections 243 of his Philosophical Investigations, Wittgenstein argues against the possibility of a private language about the subject’s inner experiences. He contends that by coining names/words (...) to name sensations and our inner experiences, we cannot create a private language. If we have a list of names, that cannot function as a language. We need predicate terms; we need the syntax to link the words in the form of a sentence. If we use private names and use the predicates from the language that everyone knows, then the private words will acquire public status like the terms ‘pain’ and ‘sensation.’ These terms are already part of the public language, and if private experiences like pain and sensation cannot be made public, we would not have these terms in our language at all. This is the reason why any application of words is public, and therefore, there is no possibility of a private language. Wittgenstein concentrates on the public rules that govern the correct application for the use of words. And the expressions are meaningful only when these are used according to rules of grammar; if these expressions do not follow any rules of grammar, these are simply meaningless. (shrink)

I examine what I take to be an important consideration for the later Wittgenstein: the understanding of a rule does not exceed or transcend an understanding of explanations or instructions in the rule. I contend that this consideration plays a central role in the later Wittgenstein's views on rule-following. I first show that it serves as a key premiss in a sceptical argument concerning our ability to follow rules. I then argue that this consideration is vital to Wittgenstein's case against (...) what I describe as a realist view of rules. This realist view requires that our understanding of a rule extend beyond what can be understood from any set of instructions or explanation. For Wittgenstein, because this is to transcend publicly available means of conveying understanding, this realist's understanding is a private understanding. He calls this private source of understanding an ‘intuition’ and the main line of argument against intuition in our understanding of a rule draws, appropriately, on what is called his ‘private language argument’. In this paper, I defend a non-verificationist reading of this argument and its use against the realist so-construed. CiteULike Connotea Del.icio.us What's this? (shrink)

In this paper I develop a philosophical account of actual mathematical infinity that does not demand ontologically or epistemologically problematic assumptions. The account is based on a simple metaphor in which we think of indefinitely continuing processes as defining objects. It is shown that such a metaphor is valid in terms of mathematical practice, as well as in line with empirical data on arithmetical cognition.

In this paper I study the development of arithmetical cognition with the focus on metaphorical thinking. In an approach developing on Lakoff and Núñez, I propose one particular conceptual metaphor, the Process → Object Metaphor, as a key element in understanding the development of mathematical thinking.
