Wittgenstein composed five original musical fragments during his transitional middle period, in which he employs musical notation as a means by which to convey his philosophical thoughts. This is an overlooked aspect of the importance of aesthetics, and musical thinking in particular, in the development of Wittgenstein’s philosophy. We explain and evaluate the way the music interlinks with Wittgenstein’s philosophical thoughts. We show the direct relation of these musical examples as precursors to some of Wittgenstein’s most celebrated ideas (the push (...) beyond the inner/outer picture, the problem of rule-following, and aspect perception). We also show how important broad aesthetic notions such as style and composition concerning the very possibility of philosophizing were to Wittgenstein. (shrink)

In this paper, I take issue with a core commitment of logical conventionalism: that we impose a logic on ourselves by adopting general linguistic conventions governing our use of logical terms, thereby determining the meanings of the logical constants and which of our inferences are valid. Drawing on Kripke’s ‘adoption problem’, I argue that general logical principles cannot be adopted, either explicitly or implicitly. I go on to argue that the meanings of our logical terms, and the validity of our (...) inferences, cannot depend on our adoption of logico-linguistic conventions. (shrink)

In Remarks on the Foundations of Mathematics, Wittgenstein notes that he has ‘not yet made the role of miscalculating clear’ and that ‘the role of the proposition: “I must have miscalculated”…is really the key to an understanding of the “foundations” of mathematics.’ In this paper, I hope to get clear on how this is the case. First, I will explain Wittgenstein's understanding of a ‘foundation’ for mathematics. Then, by showing how the proposition ‘I must have miscalculated’ differentiates mathematics from the (...) physical sciences, we will see how this proposition is the key to understanding the foundations of mathematics.

Sometimes when we describe our own sensory experiences we seem to attribute to experience itself the same sorts of familiar properties – such as shape or colour – as we attribute to everyday physical objects. But how literally should we understand such descriptions? Can there really be phenomenal elements or aspects to an experience which are, for example, quite literally square? This paper examines how these questions connect to a wide range of different commitments and theories about the metaphysics of (...) mind. In particular, I consider whether there may be phenomenological reasons to accept or reject the idea that there are elements or aspects of conscious experience itself which instantiate familiar spatial properties. I also explore how some general theses about the nature of empirical properties can motivate different answers to these questions. (shrink)

A significant discrepancy in Wittgenstein's studies is whether Philosophical Investigations contains any trace of positive philosophy, notwithstanding the author's apparent anti-theoretic position. This study argues that the so-called ‘Chapter on philosophy’ in the Investigations §§89–133 contains negative and positive vocabulary and the use of various voices through which Wittgenstein employs his primary method of language-games, thus providing a surveyable understanding of several philosophical concepts, such as knowledge and time. His positive philosophy aims to reorient our attention from understanding the theories (...) on these concepts to understanding the concepts themselves, regardless of any theorisation. (shrink)

I demonstrate that analogies, both explicit and implicit, between Wittgenstein’s discussions of rituals, aesthetics, and aspect-perception, have important payoffs in terms of understanding his notion of a “surveyable representation” (übersichtliche Darstellung) as it applies to phenomena that are not exclusively grammatical in nature. In particular, I argue that a surveyable representation of certain anthropological and aesthetic facts allows us to see, qua form of aspect-perception, internal relations and formal connections, so that the inner nature of a ritual or the solution (...) of an aesthetic puzzle is exhibited. This particular form of seeing both explains why Wittgenstein thought that hypothetical explanations about the origins of a ritual are irrelevant to appreciating its meaning and elucidates his understanding of rituals, which involves seeing “internal relations” and “formal connections.” The upshots of the account for work in anthropology are discussed.

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)

Drawing mainly from the Tractatus Logico-Philosophicus and his middle period writings, strategic issues and problems arising from Wittgenstein’s philosophy of mathematics are discussed. Topics have been so chosen as to assist mediation between the perspective of philosophers and that of mathematicians on their developing discipline. There is consideration of rules within arithmetic and geometry and Wittgenstein’s distinctive approach to number systems whether elementary or transfinite. Examples are presented to illuminate the relation between the meaning of an arithmetical generalisation or theorem (...) and its proof. An attempt is made to meet directly some of Wittgenstein’s critical comments on the mathematical treatment of infinity and irrational numbers. (shrink)

There is a line of thought, neglected in recent philosophy, according to which a priori knowable truths such as those of logic and mathematics have their special epistemic status in virtue of a certain tight connection between their meaning and their truth. Historical associations notwithstanding, this view does not mandate any kind of problematic deflationism about meaning, modality or essence. On the contrary, we should be upfront about it being a highly debatable metaphysical idea, while nonetheless insisting that it be (...) given due consideration. From this standpoint, I suggest that the Finean distinction between essence and modality allows us to refine the view. While liberal about meaning, modality and essence, the view is not without bite: it is reasonable to suppose that it is able to ward off philosophical confusions stemming from the undue assimilation of a priori to empirical knowledge.

ABSTRACTWittgenstein’s remark that one cannot follow a rule only once has generated two puzzles: how can everyone accept it to be true? and why does Wittgenstein advance it? These two puzzles have tormented commentators for decades. In this paper I put forward a new interpretation and explain away the two puzzles. I shall show that Wittgenstein’s remark is plain truth and that his motivation behind making it is to dissolve the picture theory of meaning propounded in the Tractatus. This interpretation (...) also helps us to see that Wittgenstein’s other remark, that to follow a rule is a custom, is also a grammatical one. (shrink)

The current debate concerning musical profundity was instigated, and set up by Peter Kivy in his book Music Alone (1990) as part of his comprehensive defense of enhanced formalism, a position he championed vigorously throughout his entire career. Kivy’s view of music led him to maintain utter skepticism regarding musical profundity. The scholarly debate that ensued centers on the question whether or not (at least some) music can be profound. In this study I would like to take the opportunity to (...) relate Wittgenstein’s ideas on music to this current debate, thereby achieving a twofold goal: not only to reintroduce Wittgenstein’s ideas into the current debate, but also to use the current debate as a foil to better appreciating Wittgenstein’s otherness as a philosopher of music. I argue that Wittgenstein’s unique philosophical response to the Romantic framing of the discourse concerning musical profundity —specifically, its threefold emphasis on the specificity, aboutness, and artistically exalted status of music— occasioned a view, which was bound to be glossed over by a philosophical tradition, whose origins had made it inimical to Wittgenstein’s original philosophical insights. I conclude that, in a sense, Wittgenstein occasions a paradigm shift by his philosophical thrust to undo the gravitational forces which form the current debate: the very idea of aboutness pertaining to music, and the very idea that a clear line could ever be drawn between music and language.

The object of this paper is to sketch an approach to propositions, meaning and names. The key ingredients are a Twin-Earth-inspired distinction between internal and external meaning, and a middle-Wittgenstein-inspired conception of internal meaning as role in language system. I show how the approach offers a promising solution to the problem of the meaning of proper names. This is a plea for a neglected way of thinking about these topics.

Wittgenstein’s later works are full of questions about the timing and duration of mental phenomena. These questions are often awkward ones, and Wittgenstein seems to take their awkwardness to be philosophically revealing, but if we ask what it is that these questions reveal then different interpretations are possible. This paper suggests that there are at least six different ways in which the timing of mental phenomena can be awkward. By identifying these we can give sense to some of Wittgenstein’s more (...) cryptic remarks, and doing this enables us to clarify some obscure elements in his picture of the mind, including the distinction between sensations and feelings, and his account of the rational status of those processes out of which rule-following is built.

This paper explicates Wittgenstein's vision of our place in nature and shows in what ways it is unlike and more fruitful than the picture of nature promoted by exclusive scientific naturalists. Wittgenstein's vision of nature is bound up with and supports his signature view that the task of philosophy is distinctively descriptive rather than explanatory. Highlighting what makes Wittgenstein's vision of nature special, it has been claimed that to the extent that he qualifies as a naturalist of any sort he (...) ought to be regarded as a liberal naturalist. We argue, in contrast, that focusing solely on the liberality of Wittgenstein's view of nature risks overlooking and downplaying the ways in which his philosophical clarifications can act as a platform for productively engaging with the sciences in their explanatory endeavors. We argue that Wittgenstein's vision of nature allows for a more relaxed form of naturalism in which philosophy can be a productive partner for scientific inquiry and investigation. Although this feature of Wittgenstein's vision of nature is not something that he himself emphasized, given his interests and concerns, it is an inspiring vision in an age in which philosophy must find its feet with and alongside the sciences.

This paper re-examines Kierkegaard's work with respect to the question whether truth is one or many. I argue that his famous distinction between objective and subjective truth is grounded in a unitary conception of truth as such: truth as self-coincidence. By explaining his use in this context of the term ‘redoubling’ [ Fordoblelse ], I show how Kierkegaard can intelligibly maintain that truth is neither one nor many, neither a simple unity nor a complex multiplicity. I further show how these (...) points shed much-needed light on the relationship between objective and subjective truth, conceived not as different kinds or species of truth but as different ways in which truth manifests itself as a standard of success across different contexts of inquiry.

The present article aims at investigating the political aspects of Wittgenstein’s later philosophy, focusing mainly on the Philosophical Investigations. This theme remains rather marginal within Wittgensteinian scholarship, facing the key challenge of the sparsity of explicit discussions of political issues in Wittgenstein’s writings. Based on the broader anthropological and synecdochic character of Wittgenstein’s later philosophy, the main objective of the article is to make explicit the implicit political import of some of the main themes of the Philosophical Investigations. This is (...) done by correlating them with certain political concepts and issues, such as reification, mystification, emancipation, self-institution and the common. In such a way, a new light is shed on Wittgenstein’s influence on and his relevance to contemporary political theory, while at the same time the first steps are taken for the enrichment of the discussion regarding personal and social autonomy and the critique of late capit...

This paper offers an interpretation of the later Wittgenstein's handling of the idea of an "essence of human language", and examines in particular his treatment of the 'Augustinean' vision of reference as constituting this "essence". A central theme of the interpretation is the perennial philosophical desire to impose upon linguistic meaning conceptual templates drawn from outside the forms of thought about meaning in which we engage when we exercise our capacity to speak and understand a language. The paper closes with (...) a consideration of ways in which Donald Davidson's generally congenial work on interpretation may diverge from Wittgenstein's thinking in this vicinity. (shrink)

My aim in this paper is twofold: to establish that Kierkegaard's so‐called theory of the leap strongly anticipates a line of argument that is central to Wittgenstein's so‐called rule‐following considerations; and to begin to show how Kierkegaard's work has fruitful contributions of its own to make to on‐going discussions about rules and rule‐following. The paper focuses throughout on the question of how, if at all, human rule‐following can be distinguished from behaviour that is merely mechanical or instinctual. I identify a (...) central line of argument in Wittgenstein that problematizes this question by establishing the basis our ability to follow rules in our spontaneous responses. I argue that Kierkegaard not only strongly anticipates this line of argument but also offers a distinctive story about what, at bottom, makes the difference between human rule‐following and behaviour that is merely mechanical or instinctual. In a word, on Kierkegaard's story, what makes the difference is: anxiety. (shrink)

Our commonsense notion of reality is supported by two critical assumptions for which we have little understanding: The conscious experience which underpins the observations integral to the scientific method and language, which is the method by which all theories, scientific or otherwise, are communicated. This book examines both of these matters in detail and arrives at a new theoretical foundation for understanding how nature undertakes the task of building the universe. -/- Creating Reality is a synthesis of Darwin’s The Origin (...) of Species and Douglas Hofstadter’s Gödel, Escher, Bach (GEB). It is an intellectual journey that addresses the most profound questions facing science and philosophy today and delivers the greatest transformation in the way we view the world since Darwin’s masterpiece. The book is targeted at anyone up for the cerebral challenge of thinking deeply about how we make sense of the world and our existence. The book is thoroughly researched and referenced, drawing from the most highly credential sources. -/- When we take stock of where we are in our understanding of nature, it seems that three important questions stand out for which we have few answers. More than just questions, they represent gaps in our comprehension of what makes the universe tick. These are the thematic focal points of this book: -/- • What is the nature of belief? (An examination of truth as a function of language). • What is consciousness? • What is the relationship between mathematics and the physical world? -/- The exploration of these three questions unravels the mystery behind the principal means by which we come to have knowledge of the world. So our journey begins by asking the more generic question: How do we come to know the world? The book makes no assumptions about this thing called ‘reality’ and takes a fresh look at the presuppositions underlying commonsense notions of reality. (shrink)

In this essay, I seek to demonstrate the interplay of philosophical voices – particularly, that of a platonist voice and a community-agreement-view voice – that drives Wittgenstein’s rule-following dialectic forward; and I argue that each voice succumbs to a particular form of dialectical oscillation that renders its response to the problem of rule-following philosophically inadequate. Finally, I suggest that, by seeing and taking stock of the dilemma in which these responses to the skeptical problem are caught, we can come to (...) appreciate Wittgenstein’s own view of what might constitute a proper a response to the so-called problem of rule-following. This view can be preliminarily characterized by saying that Wittgenstein’s aim is to dissolve the temptation to philosophically rebut the skeptical challenge posed by the rule-following dialectic, an aim he achieves by revealing the semantic emptiness of the apparent sentences that raise the skeptical problem.

In “Wittgenstein on Grammar, Theses and Dogmatism,” Peter Hacker addresses what he takes to be misconceptions of Wittgenstein's philosophy with respect to (1) the periodisation of his thought and to what should properly be counted as part of his work; (2) his conception of grammar since the Big Typescript (1929–33); and (3) his conception of philosophy as grammatical investigation. I argue that Hacker's restrictive conception of what ought to be considered part of Wittgenstein's philosophy and his conservative view of Wittgensteinian (...) grammar are unjustified and prevent him from appreciating the revolutionary importance of On Certainty for epistemology. Finally, while agreeing that Wittgenstein views philosophy as grammatical elucidation, I suggest some reasons for the resistance that this view has generated.In “Wittgenstein on Grammar, Theses and Dogmatism,” Peter Hacker deals with three of the “many misunderstandings, misrepresentations and misinterpretations of Wittgenstein's philosophy” (2012, 1); the first of which concerns “the periodisation of Wittgenstein's thought”; the second, the supposition that what Wittgenstein called “grammar” in PI differed fundamentally from, and was more limited than, his conception of it when he was writing the Big Typescript; and the third, the claim that what Wittgenstein took to be grammatical statements are, in fact, dogmatisms, theories or doctrines inconsistent with his meta‐philosophical remarks in PI. I address each of these concerns seriatim. (shrink)

Wittgenstein's conception of infinity can be seen as continuing the tradition of the potential infinite that begins with Aristotle. Transfinite cardinals in set theory might seem to render the potential infinite defunct with the actual infinite now given mathematical legitimacy. But Wittgenstein's remarks on set theory argue that the philosophical notion of the actual infinite remains philosophical and is not given a mathematical status as a result of set theory. The philosophical notion of the actual infinite is not to be (...) found in the mathematics of set theory, only in a certain associated philosophy – what Wittgenstein calls a certain kind of “prose”.

This paper establishes a dialogue between the later works of Wittgenstein, those of Cavell and the novels of J. M. Coetzee concerning the problem of violence, authority and the authoritative voice. By drawing on J. M. Coetzee's Waiting for the Barbarians and Diary of a Bad Year, the paper discusses lessons and insights on the nature of violence and the ways in which it can be accepted as “normal.” The term “normalization” is used in order to show how violence and (...) cruelty can become a “form of life” that develops according to its own actors, cultural practices and legitimacies.

In “Truth by Convention” W.V. Quine gave an influential argument against logical conventionalism. Even today his argument is often taken to decisively refute logical conventionalism. Here I break Quine’s arguments into two— the super-task argument and the regress argument—and argue that while these arguments together refute implausible explicit versions of conventionalism, they cannot be successfully mounted against a more plausible implicit version of conventionalism. Unlike some of his modern followers, Quine himself recognized this, but argued that implicit conventionalism was explanatorily (...) idle. Against this I show that pace Quine’s claim that implicit conventionalism has no content beyond the claim that logic is firmly accepted, implicit rules of inference can be used to distinguish the firmly accepted from the conventional. As part of my case, I argue that positing syntactic rules of inference as part of our linguistic competence follows from the same methodology that leads contemporary linguists and cognitive scientists to posit rules of phonology, morphology, and grammar. The upshot of my discussion is a diagnosis of the fallacy in Quine’s master critique of logical conventionalism and a re-opening of possibilities for an attractive conventionalist theory of logic.

In order to explain Wittgenstein’s account of the reality of completed infinity in mathematics, a brief overview of Cantor’s initial injection of the idea into set- theory, its trajectory and the philosophic implications he attributed to it will be presented. Subsequently, we will first expound Wittgenstein’s grammatical critique of the use of the term ‘infinity’ in common parlance and its conversion into a notion of an actually existing infinite ‘set’. Secondly, we will delve into Wittgenstein’s technical critique of the concept (...) of ‘denumerability’ as it is presented in set theory as well as his philosophic refutation of Cantor’s Diagonal Argument and the implications of such a refutation onto the problems of the Continuum Hypothesis and Cantor’s Theorem. Throughout, the discussion will be placed within the historical and philosophical framework of the Grundlagenkrise der Mathematik and Hilbert’s problems. (shrink)

This article explains Wittgenstein's distinction between good, bad, and vacuous modern music which he introduced in a diary entry from January 27, 1931. I situate Wittgenstein's discussion in the context of Oswald Spengler's ideas concerning the decline of Western culture, which informed Wittgenstein's philosophical progress during his middle period, and I argue that the music theory of Heinrich Schenker, and Wittgenstein's critique thereof, served as an immediate link between Spengler's cultural pessimism and Wittgenstein's threefold distinction. I conclude that Wittgenstein's distinction (...) between bad and vacuous modern music is analogous to Schenker's distinction between the compositional fallacies of the progressive and the reactionary composers of his time. Concomitantly, Wittgenstein's philosophically problematic notion of good modern music transcended the conceptual framework of both Schenker and Spengler. In this context, I examine Wittgenstein's remarks on Gustav Mahler as well as his remark on the music of the future as monophony, which, I conclude, should be understood ultimately as an ellipsis of his much later view of musical meaning and intelligibility.

According to the dominant view, the later Wittgenstein identified the meaning of an expression with its use in the language and vehemently rejected any kind of mentalism or intentionalism about linguistic meaning. I argue that the dominant view is wrong. The textual evidence, which has either been misunderstood or overlooked, indicates that at least since the Blue Book Wittgenstein thought speakers' intentions determine the contents of linguistic utterances. His remarks on use are only intended to emphasize the heterogeneity of natural (...) language. Taking into account remarks written after he finished the Investigations, I show how Wittgenstein anticipated the basic tenets of Gricean intention-based semantics. These are, in particular, the distinction between ‘natural’ and ‘non-natural’ meaning and the distinction between what a speaker means by an utterance and what the expression uttered means in the speaker’s natural language. Importantly, Wittgenstein also believed that only the meaning of the speaker determined the content of ambiguous expressions, such as ‘bank’, on a particular occasion of utterance. (shrink)

I argue for the Wittgensteinian thesis that mathematical statements are expressions of norms, rather than descriptions of the world. An expression of a norm is a statement like a promise or a New Year's resolution, which says that someone is committed or entitled to a certain line of action. A expression of a norm is not a mere description of a regularity of human behavior, nor is it merely a descriptive statement which happens to entail a norms. The view can (...) be thought of as a sort of logicism for the logical expressivist---a person who believes that the purpose of logical language is to make explicit commitments and entitlements that are implicit in ordinary practice. The thesis that mathematical statements are expression of norms is a kind of logicism, not because it says that mathematics can be reduced to logic, but because it says that mathematical statements play the same role as logical statements. ;I contrast my position with two sets of views, an empiricist view, which says that mathematical knowledge is acquired and justified through experience, and a cluster of nativist and apriorist views, which say that mathematical knowledge is either hardwired into the human brain, or justified a priori, or both. To develop the empiricist view, I look at the work of Kitcher and Mill, arguing that although their ideas can withstand the criticisms brought against empiricism by Frege and others, they cannot reply to a version of the critique brought by Wittgenstein in the Remarks on the Foundations of Mathematics. To develop the nativist and apriorist views, I look at the work of contemporary developmental psychologists, like Gelman and Gallistel and Karen Wynn, as well as the work of philosophers who advocate the existence of a mathematical intuition, such as Kant, Husserl, and Parsons. After clarifying the definitions of "innate" and "a priori," I argue that the mechanisms proposed by the nativists cannot bring knowledge, and the existence of the mechanisms proposed by the apriorists is not supported by the arguments they give.

Homo deceptus is a book that brings together new ideas on language, consciousness and physics into a comprehensive theory that unifies science and philosophy in a different kind of Theory of Everything. The subject of how we are to make sense of the world is addressed in a structured and ordered manner, which starts with a recognition that scientific truths are constructed within a linguistic framework. The author argues that an epistemic foundation of natural language must be understood before laying (...) claim to any notion of reality. This foundation begins with Ludwig Wittgenstein’s Tractatus Logico-Philosophicus and the relationship of language to formal logic. Ultimately, we arrive at an answer to the question of why people believe the things they do. This is effectively a modification of Alfred Tarski’s semantic theory of truth. The second major issue addressed is the ‘dreaded’ Hard Problem of Consciousness as first stated by David Chalmers in 1995. The solution is found in the unification of consciousness, information theory and notions of physicalism. The physical world is shown to be an isomorphic representation of the phenomenological conscious experience. New concepts in understanding how language operates help to explain why this relationship has been so difficult to appreciate. The inclusion of concepts from information theory shows how a digital mechanics resolves heretofore conflicting theories in physics, cognitive science and linguistics. Scientific orthodoxy is supported, but viewed in a different light. Mainstream science is not challenged, but findings are interpreted in a manner that unifies consciousness without contradiction. Digital mechanics and formal systems of logic play central roles in combining language, consciousness and the physical world into a unified theory where all can be understood within a single consistent framework.

In a recent article, John McDowell has criticised Warren Goldfarb for attributing an anti-realist conception of linguistic understanding to Wittgenstein. 1 I argue that McDowell is right to reject Goldfarb's anti- realism, but does so for the wrong reasons. I show that both Goldfarb's and McDowell's interpretations are vitiated by the fact that they do not pay attention to Wittgenstein's positive claims about understanding, in particular his claim that understanding is a kind of ability. The cause of this oversight lies (...) in their endorsement of an excessively anti-systematic or “therapeutic” reading of Wittgenstein. (shrink)

Neo-Fregeans need their stipulation of Hume's Principle — $NxFx=NxGx \leftrightarrow \exists R (Fx \,1\hbox {-}1_R\, Gx)$ — to do two things. First, it must implicitly define the term-forming operator ‘Nx…x…’, and second it must guarantee that Hume's Principle as a whole is true. I distinguish two senses in which the neo-Fregeans might ‘stipulate’ Hume's Principle, and argue that while one sort of stipulation fixes a meaning for ‘Nx…x…’ and the other guarantees the truth of Hume's Principle, neither does both.

Review of the translation of Ludwig Wittgenstein book: Observações Filosóficas. São Paulo: Edições Loyola, 2005. Tradução (do inglês) por Adail Sobral e Maria Stela Gonçalves.

Between April and November 1912, Bertrand Russell and Ludwig Wittgenstein were engaged in a joint philosophical program. Wittgenstein‘s meeting with Gottlob Frege in December 1912 led, however, to its dissolution – the joint program was abandoned. Section 2 of this paper outlines the key points of that program, identifying what Russell and Wittgenstein each contributed to it. The third section determines precisely those features of their collaborative work that Frege criticized. Finally, building upon the evidence developed in the preceding two (...) sections, section 4 recasts along previously undeveloped lines Wittgenstein‘s logical–philosophical discoveries in the two years following his encounter with Frege in 1912. The paper concludes, in section 5, with an overview of the dramatic consequences the Frege-Wittgenstein critique had for Russell‘s philosophical development. (shrink)

The predominant interpretation of Wittgenstein's later remarks on religion takes him to hold that all religious utterances are non-scientific, and to hold that the way to show that religious utterances are non-scientific is to identify and characterise the grammatical rules governing their use. This paper claims that though this does capture one strand of Wittgenstein's later thought on religion, there is an alternative strand of that thought which is quite different and more nuanced. In this alternative strand Wittgenstein stresses that (...) religious utterances and beliefs can come in both scientific and non-scientific varieties. More than that, he claims that the grammar of religious utterances, and the logic of religious beliefs, is often complex – in that individual utterances and beliefs will often be mixed between, indeterminate between, or fluid between being scientific and being non-scientific. This complexity means that it will often be unhelpful to try to pin down one particular grammar or logic for a given utterance or belief. Wittgenstein therefore suggests a new method of grammatical and logical investigation, which is less likely to distort complex grammars or logics by being overly simplistic or rigid. This method is to use simple examples of utterances and beliefs as objects of comparison, so as to illuminate the different aspects of the more complex actual utterances and beliefs under examination. This alternative strand in Wittgenstein's later remarks on religion is a manifestation of a broader strand of Wittgenstein's later thought as a whole, which was first described by Friedrich Waismann, and later developed by Gordon Baker and Oskari Kuusela. The paper concludes by providing examples of religious beliefs which are logically mixed, indeterminate, and fluid, and showing how simple objects of comparison can be used to illuminate them.

L'A. défend la thèse selon laquelle Wittgenstein développe une conception pragmatique et linguistique des relations internes qui définissent les vérités nécessaires: 1) qui n'implique pas l'analyticité de toutes les propositions exprimant des relations internes, 2) qui établit une distinction entre l'analytique et le synthétique, 3) qui s'avère compatible avec la critique de l'analyticité entreprise par Quine.

Koopman’s book revolves around the notion of transition, which he proposes is one of the central ideas of the pragmatist tradition but one which had not previously been fully articulated yet nevertheless shapes the pragmatist attitude in philosophy. Transition, according to Koopman, denotes “those temporal structures and historical shapes in virtue of which we get from here to there”. One of the consequences of transitionalism is the understanding of critique and inquiry as historical pro...

When it comes to Wittgenstein's philosophy of mathematics, even sympathetic admirers are cowed into submission by the many criticisms of influential authors in that field. They say something to the effect that Wittgenstein does not know enough about or have enough respect for mathematics, to take him as a serious philosopher of mathematics. They claim to catch Wittgenstein pooh-poohing the modern set-theoretic extensional conception of a real number. This article, however, will show that Wittgenstein's criticism is well grounded. A real (...) number, as an 'extension', is a homeless fiction; 'homeless' in that it neither is supported by anything nor supports anything. The picture of a real number as an 'extension' is not supported by actual practice in calculus; calculus has nothing to do with 'extensions'. The extensional, set-theoretic conception of a real number does not give a foundation for real analysis, either. The so-called complete theory of real numbers, which is essentially an extensional approach, does not define (in any sense of the word) the set of real numbers so as to justify their completeness, despite the common belief to the contrary. The only correct foundation of real analysis consists in its being 'existential axiomatics'. And in real analysis, as existential axiomatics, a point on the real line need not be an 'extension'.

One calls a lot of things propositions. If one sees this, then one can discard the idea Russell and Frege had that logic is a science of certain objects – propositions, functions, the logical constants – and that logic is like a natural science such as zoology and talks about these objects as zoology talks of animals. Like a natural science, it could supposedly discover certain relations. For example, Keynes claimed to discover a probability relation which was like implication, yet (...) not quite implication. But logic is a calculus, not a natural science, and in it one can make inventions but not discoveries.Giving grounds, however, justifying the evidence, comes to an end; – but the end is not certain propositions' striking us immediately as true, i.e. it is not a kind ofseeingon our part; it is ouracting, which lies at the bottom of the language-game.

This is a paper about the way language meshes with life. It focuses on Ludwig Wittgenstein’s later work, and compares it with Leo Tolstoy and Saint Augustine’s confessions. My aim is to better understand in this way what it means to have meaning in language, as well as meaning in life.

Reasons motivate our intentions and thus our actions, justify our beliefs, ground our hopes and connect our feelings of shame and pride to our thoughts. Given that intentions, beliefs and emotions are intentional states, intentionality is strongly connected with normativity. Yet what is more precisely their relationship? Some philosophers, notably Brandom and McDowell, contend at places that intentionality is intrinsically normative. In this paper, we discuss Brandom and McDowell’s thesis and the arguments they provide for its defence. In contrast to (...) what they hold, we argue that neither reference intentionality nor content intentionality are intrinsically normative, although at least content intentionality has normative implications. More precisely, we argue that neither species of intentionality are normative from a semantical viewpoint, because being in an intentional state is not being in a state that is semantically correct or incorrect. Nevertheless, being in a state endowed with content may be a reason for believing or acting. Thus, we argue that content intentionality has normative implications. More precisely, we argue that any content is such that, if it is the content of a state that is sensitive to reasons - as judging paradigmatically is – then it entitles the subject of that state to have further states or to act in certain ways.

This paper explores the role of phenomenology in the understanding of the cognitive processes of coupling/decoupling, defending the Wittgensteinian idea that phenomenology can play a crucial role as a description of immediate (social) experience. We argue that epistemic feelings can provide a phenomenological description of the development of a subject's everyday experience, tracking the transition from the processes of coupling/decoupling and recoupling with the world. In particular, the feeling of familiarity, whose key features can be considered the core of epistemic (...) feelings, signals a novelty in the flow of experience that makes sense and is worthy of remarking on or even articulating. By describing the primary features and sources of the feeling of familiarity, we highlight a conceptual tension related to its sources, which could be based on processing both fluency and discrepancy. We proposed a solution to the conceptual tension by introducing two levels of the feeling of familiarity: epistemic and experiential. (shrink)

In recent work, Sören Stenlund (2015) contextualizes Wittgenstein’s philosophy of mathematics as aligned with the tradition of symbolic mathematics. In the early modern era, mathematicians began using purely formal methods disconnected from any obvious empirical applications, transforming their subject into a symbolic discipline. With this, Stenlund argues, they were freeing themselves of ancient ontological presuppositions and discovering the ultimately autonomous nature of mathematical symbolism, which eventually formed the basis for Wittgenstein’s thinking. A crucial premise of Wittgenstein’s philosophy of mathematics, on (...) this view, is that the development of mathematical concepts is independent of any ontological implications and occurs in principle without normative connections to empirical applicability. This paper critically examines this narrative and arrives at the conclusion that Stenlund’s view of mathematical progress is in stark contrast to the later Wittgenstein’s writing, which emphasizes links between symbolisms and their applications.
