The purpose of this paper is twofold: (1) to clarify Ludwig Wittgenstein’s thesis that colours possess logical structures, focusing on his ‘puzzle proposition’ that “there can be a bluish green but not a reddish green”, (2) to compare modeltheoretical and gametheoretical approaches to the colour exclusion problem. What is gained, then, is a new gametheoretical framework for the logic of ‘forbidden’ (e.g., reddish green and bluish yellow) colours. My larger aim is to discuss phenomenological principles of the demarcation of the (...) bounds of logic as formal ontology of abstract objects. (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”.

Kant, Wittgenstein, and Husserl all held that visual awareness of objects requires visual awareness of the space in which the objects are located. There is a lively debate in the literature on spatial perception whether this view is undermined by the results of experiments on a Balint’s syndrome patient, known as RM. I argue that neither of two recent interpretations of these results is able to explain RM’s apparent ability to experience motion. I outline some ways in which each interpretation (...) may respond to this challenge, and suggest which way of meeting the challenge is preferable. I conclude that RM retains some awareness of the larger space surrounding the objects he sees. (shrink)

The Abhidharma Buddhist revisionary metaphysics aims to provide an intellectually and morally preferred picture of the world that lacks a self. The first part of the paper claims that the Abhidharma ‘no-self’ view can be plausibly interpreted as a no-ownership view, according to which there is no locus or subject of experience and thus no owner of mental or bodily awarenesses. On this interpretation of the no-self view, the Abhidharma Buddhist metaphysicians are committed to denying the ownership of experiences, and (...) thereby apparently obliged to explain our purported experience of ownership. My experiences seemingly come with the sense that I am the one who is undergoing this experience. But is there a really an experience of ownership—namely, an experience of being a subject that underlies our sense of ownership? I argue that there is nothing that it is like to be an owner of experiences, in the sense that there is no experiential phenomenology associated with the ownership of experience. The second part of the paper argues that, since there is no experience of ownership, there is no onus on the Abhidharma philosopher to give an explanation of the sense of ownership. (shrink)

In recent years, philosophers have used expressions of Wittgenstein’s (e.g. “language-games,” “form of life,” and “family resemblance”) in attempts to conceive of the discipline of philosophy in a broad, open, and perhaps global way. These Wittgenstein-inspired approaches indicate an awareness of the importance of cultural and historical diversity for approaching philosophical questions. While some philosophers have taken inspiration from Wittgenstein in embracing contextualism in philosophical hermeneutics, Wittgenstein himself was more instrumental than contextual in his treatment of other philosophers; his focus (...) in his writings was on his own philosophical problems. Does this mean that Wittgensteinian philosophy is a poor resource after all for comparative, cross-cultural, or globally-engaged philosophy (i.e. if it is properly Wittgensteinian)? In this article, I examine the relevance of Wittgenstein to contextually-sensitive philosophy through studies of his conceptions of history and culture, his interest in Spengler’s philosophy of history, and recent scholarship by Hans-Johann Glock and Hans Sluga on the place of contextualism in Wittgenstein’s analysis of philosophical problems. Ultimately, this article advances the view that there are strong resources in Wittgenstein’s philosophy for those seeking a more globally-engaged approach to the field. (shrink)

My point of departure is the idea that Wittgenstein's work, especially his later work with its explicit emphasis on practices, seeks to engage a reader who is likely to come to philosophy with a certain cast of mind that includes unexamined commitments from a particular cultural context. I show how a substantial number of remarks by Wittgenstein in which he addresses cultural topics bring out the importance of the quite specific connections he saw between the philosophical problems with which he (...) grappled and the historical cultural context in which those problems have arisen. Not only is a grasp of this aspect of his writing integral to a proper understanding of Wittgenstein as a thinker, bringing out these connections serves to put these remarks into a coherent conceptual framework. In assessing the relation of Wittgenstein's cultural concerns to his engagement with metaphysics, I show how his development of Spengler's thought is an important connecting link. Particularly important for this analysis will be my discussion of Wittgenstein's understanding and employment of the concept of a Betrachtungsform , as well as a few closely related concepts. I then offer an interpretation of what I believe to be the significance of the connection in his later thought between his philosophical activity and his views about the modern West. (shrink)

In the early-to-mid 1930s, Wittgenstein investigated solipsism via the philosophy of language. In this paper, I want to reopen Wittgenstein's ‘grammatical’ examination of solipsism.Wittgenstein begins by considering the thesis that only I can feel my pains. Whilst this thesis may tempt us towards solipsism, Wittgenstein points out that this temptation rests on a grammatical confusion concerning the phrase ‘my pains’. In Section 1, I unpack and vindicate his thinking. After discussing ‘my pains’, Wittgenstein makes his now famous suggestion that the (...) word ‘I’ has two distinct uses: a subject-use and an object-use. The purpose of Wittgenstein's suggestion has, however, been widely misunderstood. I unpack it in Section 2, explaining how the subject-use connects with a phenomenological language, and so again tempts us into solipsism. In Sections 3–4, I consider various stages of Wittgenstein's engagement with this kind of solipsism, culminating in a rejection of solipsism via reflections on private languages. (shrink)

The paper provides an interpretation of Wittgenstein’s claim that a mathematical proof must be surveyable. It will be argued that this claim specifies a precondition for the applicability of the word ‘proof’. Accordingly, the latter is applicable to a proof-pattern only if we can come to agree by mere observation whether or not the pattern possesses the relevant structural features. The claim is problematic. It does not imply any questionable finitist doctrine. But it cannot be said to articulate a feature (...) of our actual usage of the word ‘proof’. The claim can be dissociated, however, from two tenable doctrines of Wittgenstein, namely that proofs can be used as paradigms for corresponding proof concepts and that a proof is not an experiment. (shrink)

According to A-theories of time, the metaphysical ground of change and dynamicity is provided by a continuous shifting in which events are past, present and future (A-determinations). It is often claimed that these theories make better sense of our experience of dynamicity than their rival, the B-theories; according to the latter, dynamicity is grounded solely in the irreducible earlier-than relations (B-relations) which obtain between events or states of affairs. In this paper, I argue that the experience of time's dynamicity, on (...) the contrary, cannot be accounted for solely in terms of representations of irreducible A-determinations, because any representation which is adequate to ground these experiences must itself involve representation of irreducible B-relations, while it needs not involve representation of A-determinations. Even if, as a matter of contingent fact, our experiences of dynamicity consisted of representations of successions of A-determinations, what would account for them being experiences of dynamicity would be solely the B-theoretic relations of succession, rather than the irrelevant A-theoretic nature of the relata.

According to Wittgenstein, internal relations are such that, once their terms are given, it is unthinkable that they do not hold. In his early philosophy, the concept of internal relation plays a central role in his views on meaning. The present paper addresses the question of how Wittgenstein's views about internal relations develop during his years of transition (1930-32). In particular, it investigates the connections between the concepts of internal relation, logical multiplicity, and aspect seeing in two thematic fields: (1) (...) Wittgenstein's discussion of the relation between an expectation and what fulfils it, and (2) his discussion of the relation between a sign and an action guided by it. (shrink)

‘Does the planetary impact of Western thought allow for a real dialogue among civilizations?’ This arresting question was set to the lecturers at the first international symposium of the Iranian Centre for the Study of Civilizations, which took place in Tehran in October 1977. Plans were made for a second symposium to be held in January 1979 under the title ‘The Limits of Knowledge According to Different World-views’. The Director's letter of invitation amplified the theme in a series of questions:For (...) instance, is the agnosticism which has now extended to a world-wide level the consequence of the destruction of objective reason, namely the universal logos, as conceived earlier in the great metaphysical doctrines of the East and the West? Is there any organic link among these: the creation of modern political myths, the individual's fragmentation and the reduction of thought to its mere instrumentality? Is knowledge limited solely to our calculating reason or can it lead to spheres raising us above the limits determined by Kant in his Critique of Pure Reason? (shrink)

The unpleasantness of pain motivates action. Hence many philosophers have doubted that it can be accounted for purely in terms of pain’s possession of indicative representational content. Instead, they have explained it in terms of subjects’ inclinations to stop their pains, or in terms of pain’s imperative content. I claim that such “noncognitivist” accounts fail to accommodate unpleasant pain’s reason-giving force. What is needed, I argue, is a view on which pains are unpleasant, motivate, and provide reasons in virtue of (...) possessing content that is indeed indicative, but also, crucially, evaluative. (shrink)

In this paper I contrast conceptions of self from two perspectives: an individualistic orientation and a communitarian approach. In doing so, the philosophical justification is Wittgenstein’s idea that individualism is produced and reinforced as a way of being, thinking and interacting in community. With this contextual frame, I argue that we are shaped by the language practices of our community to ascribe meaning and interpret our own relationships with others through our language lexicon and grammar. To illustrate the communitarian perspective (...) I refer to Māori perspectives in which connectedness is axiomatic: in particular the concepts of whanaungatanga and whakapapa, as described by Ka’ai and Metge. On the basis that such concepts are predicated on language use, I suggest that we can learn the grammar of engagement in a discursive context that emphasises connectedness just as easily as in one which is founded on separateness. I argue that interacting with an other is to engage with the ideas, beliefs, and values that shape their language, even as we expose our own. Engaging between individualistic and communitarian understandings is presented as learning to bridge language gaps between different social constructs and understandings of reality. (shrink)

What we observe, through our usually limited lens, is that differential growing of space determines forms -characterized by their shape, size and coloration. As non-Euclidean geometrical mathematics have proclaimed: forms are manifestations of the curvature of space. Physics and other natural laws impose mathematical structural restrictions to biological forms. The molecules comprising any living form become arranged in specific ways in response to physical forces as well as chemical and biochemical conditions. Over time, such forms inherit additional historical restrictions that (...) make up their meaning, their semiotics. Color does not escape from this orthogenic reality. In this study, we present the colored pattern of the connexivum of Triatoma maculata, an insect vector of the etiologic agent of Chagas disease. This model is used as an example to appreciate mimicry under a heterodox and provocative approach. We unveil that beyond 1) mathematical and 2) historical semiotic restrictions of T. maculata mimesis of a yellowish-black alternating pattern, there are also 3) artistic interpretations; where metaphysics of life, beyond human perspective, is included.

Many interpreters of the Tractatus accept that the book endorses an argument for simples based on the reflection that, since complexes exist only contingently, if names referred to complexes the propositions in which they figure would lack sense if their referents went out of existence. More specifically, most interpreters read 2.0211-2.0212 as putting forward this argument. My main goal in this paper is to attack this reading and to put forward an alternative. I argue that there is no good reason (...) for thinking that the Tractatus advances this argument. I argue that 2.0211-2, in particular, should not be read in this way, and put forward an alternative reading of the passage. (shrink)

The goal of this paper is to connect Rota's discussion of the Husserlian notion of Fundierung with Rota's project of giving combinatorics a foundation in his 1964 paper ‘On the foundations of combinatorial theory I’. Section 2 gives the basic tenets of this seminal paper. Sections 3 and 4 spell out the connections made there between Rota's philosophical writings and his mathematical achievements. Section 5 shows how these two developments fit into Rota's analysis of the place of combinatorics in mathematics.

In this article, I show and discuss the relevance of Wittgenstein's arguments as to the spatial structure of sight to recent issues in the philosophy of mind. The first, bearing upon the dimensionality of the manifolds at play in depiction, plays a critical role in Clark's attempt to provide an independent account ofqualiaand of their differentiative properties. The second, pertaining to the properly spatial structure formed by the data of sight, is explicitly appealed to in the debate on the realistic (...) character of any genuinely spatial scheme. I argue that if Wittgenstein rightly assumes that the simultaneous presence of sensible places in vision is a key condition for objectivity, he fails nevertheless to warrant the allegedly realistic character of the scheme employed in his own search for a phenomenological description of the visual field.

The view of Wittgenstein as a ‘tragic’ philosopher of education is examined. Friesen’s claim rests on an interpretation of the way in which Wittgenstein uses the German term ‘Abrichtung’. This involves the claim that Wittgenstein saw training activities closely analogous to the breaking of an animal’s will. Close examination of various of the later texts of Wittgenstein and comparison of the original German with the English translation does not bear out this claim. Wittgenstein used ‘Abrichtung’ and related terms in his (...) own way and for his own purposes. The picture that emerges from an overview of Wittgenstein’s use of these terms is that he sees training as a variegated rather than a single kind of activity. (shrink)

Three kinds of knowledge usually recognised by epistemologists are identified and their relevance for curriculum design is discussed. These are: propositional knowledge, know-how and knowledge by acquaintance. The inferential nature of propositional knowledge is argued for and it is suggested that propositional knowledge in fact presupposes the ability to know how to make appropriate inferences within a body of knowledge, whether systematic or unsystematic. This thesis is developed along lines suggested in the earlier work of Paul Hirst. The different kinds (...) of know-how and their relationships are discussed and it is suggested that they occupy different places and different relationships in any curricular hierarchy. The changing role that knowledge by acquaintance plays within this hierarchy is also discussed. Implications of this account for the current National Curriculum and for curriculum design more generally are discussed, looking at History, Science and Design Technology as examples. (shrink)

The paper argues that an internal debate within Wittgensteinian philosophy leads to issues associated rather with the later philosophy of Martin Heidegger. Rush Rhees's identification of the limitations of the notion of a “language game” to illuminate the relation between language and reality leads to his discussion of what is involved in the “reality” of language: “anything that is said has sense-if living has sense, not otherwise.” But what is it for living to have sense? Peter Winch provides an interpretation (...) and application of Rhees's argument in his discussion of the “reality” of Zande witchcraft and magic in “Understanding a Primitive Society”. There he argues that such sense is provided by a language game concerned with the ineradicable contingency of human life, such as (he claims) Zande witchcraft to be. I argue, however, that Winch's account fails to answer the question why Zande witchcraft can find no application within our lives. I suggest that answering this requires us to raise the question of why Zande witchcraft “fits” with their other practices but cannot with ours, a question of “sense” which cannot be answered by reference to another language game. I use Joseph Epes Brown's account of Native American cultures (in Epes Brown 2001) as an exemplification of a form of coherence that constitutes what we may call a “world”. I then discuss what is involved in this, relating this coherence to a relation to the temporal, which provides an internal connection between the senses of the “real” embodied in the different linguistic practices of these cultures. I relate this to the later Heidegger's account of the “History of Being”, of the historical worlds of Western culture and increasingly of the planet. I conclude with an indication of concerns and issues this approach raises, ones characteristic of “Continental” rather than Wittgensteinian philosophy. (shrink)

The main question addressed by this article is this: How should one understand the role of the sentences of the Tractatus, given Wittgenstein’s statement that they are nonsensical? I begin with a presentation of three general principles of interpretation in order to avoid answering the question in an inappropriate way. I then move on to a short presentation and commentary on a selection of readings – namely, the ineffabilist, resolute and elucidatory ones – and elaborate the answers given by advocates (...) of these to the question explored here. I agree on many points with resolute and elucidatory readings: the Tractatus presents an austere conception of nonsense, and is not a book that seeks to present ontological or semantic theories. I point out, however, that these readings cannot fully explain the nature of Tractarian elucidations. Then I discuss those parts of the Tractatus which refer to the sentences of the book itself. The main proposal of my own approach is this: Tractarian elucidations should be construed as rules of translation, in that they show how to substitute certain expressions for others. They enable us to construct a notation in which everything that is expressible in ordinary language can be said perspicuously. (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)

The Adam Smith problem refers to a claimed inconsistency between the Theory of Moral Sentiments and the Wealth of Nations, regarding the portrayal of human nature in these two books. Previous research predominantly resolved the claimed inconsistency by uncovering virtuous, less selfish character traits in the Wealth of Nations. This article voices caution. I acknowledge – on methodological grounds – fundamental differences regarding the portrayal of human nature in Smith’s behavioral ethics, i.e. the Theory of Moral Sentiments, as compared with (...) Smith’s economic research. The key argument is that Smith’s two books address different research problems and hence do not, need not and cannot adopt the same view of human nature – for methodological reasons, so my argument. Adam Smith scholarship overlooked that Smith himself in considerable degrees understood “economic man” as a heuristic abstraction. I connect to the philosophies of science of Imre Lakatos and Karl Popper. (shrink)

In this paper, I will defend the claim that there are three existence properties: the second-order property of being instantiated, a substantive first-order property (or better a group of such properties) and a formal, hence universal, first-order property. I will first try to show what these properties are and why we need all of them for ontological purposes. Moreover, I will try to show why a Meinong-like option that positively endorses both the former and the latter first-order property is the (...) correct view in ontology. Finally, I will add some methodological remarks as to why this debate has to be articulated from the point of view of reality, i.e., by speaking of properties, rather than from the point of view of language, i.e., by speaking of predicates (for such properties).

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)

Here, the logical behaviour of negation in Wittgenstein's Tractatus is compared with Demos' account of denial. Even if we hold negation as a pure syntactical device, at least in some context, it brings a handful of complex semantic information – potentially an infinite amount. We advocate then the existence of at least two negations due to the existence of two different and non-reducible types of exclusion. The first negation is a Tractarian and classical one, based on the notion of contradiction, (...) whereas the second is a non-classical negation, based on the notion of contrariety. (shrink)

Desire satisfaction has not received detailed philosophical examination. Yet intuitive judgments about the satisfaction of desires have been used as data points guiding theories of desire, desire content, and the semantics of ‘desire’. This paper examines desire satisfaction and the standard propositional view of desire. Firstly, I argue that there are several distinct concepts of satisfaction. Secondly, I argue that separating them defuses a difficulty for the standard view in accommodating desires that Derek Parfit described as ‘implicitly conditional on their (...) own persistence’, a problem posed by Shieva Kleinschmidt, Kris McDaniel, and Ben Bradley. The solution undercuts a key motivation for rejecting the standard view in favour of more radical accounts proposed in the literature. (shrink)

The way physics and other parts of science work can be explained in the framework of radical constructivism. However, this constructivist view itself shows that a uniquily accepted epistemology, constructivism or any other, would not be an advantage for the developmentof science. Unlike physics some parts of science successfully use constructivist concepts inside their theories. Because this is the case particularly in learning theory, constructivist ideas can help to improve physics teaching.

Many philosophers have held that it is not possible to experience a spatial object, property, or relation except against the background of an intact awareness of a space that is somehow ‘absolute’. This paper challenges that claim, by analyzing in detail the case of a brain-damaged subject whose visual experiences seem to have violated this condition: spatial objects and properties were present in his visual experience, but space itself was not. I go on to suggest that phenomenological argumentation can give (...) us a kind of evidence about the nature of the mind even if this evidence is not absolutely incorrigible. (shrink)

El artículo examina el pensamiento de Wittgenstein sobre el lenguaje del dolor en la primera y tercera persona. Se subrayan ciertas diferencias gramaticales importantes, según el típico método lingüístico de este filósofo, no sólo respecto a esas dos perspectivas, sino también con relación al uso de verbos cognitivos como “sentir” y “saber”. El examen de muchos textos sugiere ciertos puntos acerca de las relaciones entre las vivencias personales, la captación empática de las vivencias ajenas y su traducción conceptual. Una breve (...) comparación con algunos textos de Tomás de Aquino completa la propuesta de la existencia de un conocimiento no intencional. (shrink)

El presente trabajo explora la posible afinidad de método entre las obras de Walter Benjamin y Ludwig Wittgenstein. El intento por parte de Benjamin de desarrollar un nuevo método de representación histórica gravita en torno a la categoría de “origen”, la cual sostiene sus más importantes trabajos de investigación histórica. En paralelo al trabajo de Benjamin, Wittgenstein dedicó una especial atención al problema de una exposición filosófica de los fenómenos, en especial en sus investigaciones sobre el lenguaje, a través de (...) categorías como la “representación perspicua” o la “visión de aspectos”. La filiación común de la reflexión de ambos autores en la morfología de Goethe nos permitirá definir el perfil de un posible enfoque estético para la investigación filosófica, dirigida a captar la generalidad de los fenómenos sin renunciar a salvaguardar su singularidad única.

The long‐standing issue of Wittgenstein's controversial remarks on Gödel's Theorem has recently heated up in a number of different and interesting directions [,, ]. In their, Juliet Floyd and Hilary Putnam purport to argue that Wittgenstein's‘notorious’ “Contains a philosophical claim of great interest,” namely, “if one assumed. that →P is provable in Russell's system one should… give up the “translation” of P by the English sentence ‘P is not provable’,” because if ωP is provable in PM, PM is ω ‐inconsistent, (...) and if PM is ω‐inconsistent, we cannot translate ‘P’as ’P is not provable in PM’because the predicate‘NaturalNo.’in ‘P’“cannot be…interpreted” as “x is a natural number.” Though Floyd and Putnam do not clearly distinguish the two tasks, they also argue for “The Floyd‐Putnam Thesis,” namely, that in the 1930's Wittgenstein had a particular understanding of Gödel's First Incompleteness Theorem. In this paper, I endeavour to show, first, that the most natural and most defensible interpretation of Wittgenstein's and the rest of is incompatible with the Floyd‐Putnam attribution and, second, that evidence from Wittgenstein's Nachla strongly indicates that the Floyd‐ Putnam attribution and the Floyd‐Putnam Thesis are false. By way of this examination, we shall see that despite a failure to properly understand Gödel's proof—perhaps because, as Kreisel says, Wittgenstein did not read Gödel's 1931 paper prior to 1942‐Wittgenstein's 1937–38, 1941 and 1944 remarks indicate that Gödel's result makes no sense from Wittgenstein's own perspective.

This paper offers a reconstruction of Wittgenstein's discussion on inductive proofs. A "algebraic version" of these indirect proofs is offered and contrasted with the usual ones in which an infinite sequence of modus pones is projected.

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.

I examine what I shall call meta-philosophy: a philosophical examination into what philosophy is, can be, should be, something of what it has been, what the point (if any) of it is and what, if anything, it can contribute to our understanding of and the making sense of our lives, including our lives individually and together, and of the social order in which we live.

It is often held that Wittgenstein had to introduce numbers in elementary propositions due to problems related to the so-called colour-exclusion problem. I argue in this paper that he had other reasons for introducing them, reasons that arise from an investigation of the continuity of visual space and what Wittgenstein refers to as ‘intensional infinity’. In addition, I argue that the introduction of numbers by this route was prior to introducing them _via_ the colour-exclusion problem. To conclude, I discuss two (...) problems that Wittgenstein faced in the writings before _Some Remarks on Logical Form _, problems that are independent of the colour-exclusion problem but dependent on the introduction of numbers in elementary propositions.

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)

This paper is more than a plea for Rhees’ reading of the work of Wittgenstein (particularly of On Certainty). My interest in Rhees’ interpretation lies on its resemblance with my own reading, on the one hand, and on its being (surprisingly) unmentioned by other interpreters, on the other. The two core aims of this paper focus on Rhees’ main ideas. First, I argue that although certain facts that are accepted beyond doubt belong to the method, which in turn is included (...) in grammar, this does not mean that these facts are expressions of rules of grammar. Second, I argue that grammar is not conditioned by a certain class of facts (i.e. general facts of nature), but a language-game is possible because we do not call in question certain facts (i.e. grammar is not conditioned by something like ontology). The point is that those facts that are not called in question are beyond truth and falsity, but this does not mean that these facts must be true. The logical role these facts (and the sentences used to express them) play in a language-game is not that of being true or false. Moreover, grammar itself constitutes what is meant by ‘object’, ‘fact’, or ‘general fact of nature’. (shrink)

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)

Cora Diamond has recently criticised as mere legend the interpretation of a quip of Ramsey's, contained in the epigraph below, which takes him to be objecting to or rejecting Wittgenstein's Tractarian distinction between saying and showing. Whilst I agree with Diamond's discussion of the legend, I argue that her interpretation of the quip has little evidential support, and runs foul of a criticism sometimes made against intuitionism. Rather than seeing Ramsey as making a claim about the nature of propositions, as (...) Diamond does, we should understand him as making a claim about the grammar of the logical connectives. Such a view coheres with the extant evidence of the nature of Wittgenstein's and Ramsey's 1929 philosophical encounters. It is also compatible with attributing to Ramsey a recognition of Wittgenstein's distinction and with denying that criticising it is the lesson of the quip. (shrink)

We argue that all general concepts are family resemblance concepts. These include concepts introduced by ostension, such as colour(s). Concepts of colour and of each of the specific colours are family resemblance concepts because similarities concerning an open‐ended range of colour or of appearance features crop up and disappear. After discussing the notion of “same colour” and Wittgenstein's use of the phrase “our colours”, we suggest family resemblance concepts in one tradition can often be extended to family resemblance concepts in (...) another tradition, illustrated by Wittgenstein's use of the words Spiel and “game”.
