When in May 1930, the Council of Trinity College, Cambridge, had to decide whether to renew Wittgenstein's research grant, it turned to Bertrand Russell for an assessment of the work Wittgenstein had been doing over the past year. His verdict: "The theories contained in this new work . . . are novel, very original and indubitably important. Whether they are true, I do not know. As a logician who likes simplicity, I should like to think that they are not, but (...) from what I have read of them I am quite sure that he ought to have an opportunity to work them out, since, when completed, they may easily prove to constitute a whole new philosophy." "[ Philosophical Remarks ] contains the seeds of Wittgenstein's later philosophy of mind and of mathematics. Principally, he here discusses the role of indispensable in language, criticizing Russell's The Analysis of Mind . He modifies the Tractatus 's picture theory of meaning by stressing that the connection between the proposition and reality is not found in the picture itself. He analyzes generality in and out of mathematics, and the notions of proof and experiment. He formulates a pain/private-language argument and discusses both behaviorism and the verifiability principle. The work is difficult but important, and it belongs in every philosophy collection."--Robert Hoffman, Philosophy "Any serious student of Wittgenstein's work will want to study his Philosophical Remarks as a transitional book between his two great masterpieces. The Remarks is thus indispensible for anyone who seeks a complete understanding of Wittgenstein's philosophy."--Leonard Linsky, American Philosophical Association. (shrink)

The _Philosophical Investigations_ of Ludwig Wittgenstein present his own distillation of two decades of intense work on the philosophies of mind, language and meaning.

The objective of this article is to try to elucidate Wittgenstein’s ex-travagant thesis that each and every mathematical advancement involves some “semantical mutation”, i.e., some alteration of the very meanings of the terms involved. To do that we will argue in favor of the idea of a “modal incompati-bility” between the concepts involved, as they were prior to the advancement, and what they become after the new result was obtained. We will also argue that the adoption of this thesis profoundly (...) alters the traditional way of con-struing the idea of “progress” in mathematics. (shrink)

This article argues, first, that the fundamental structure of the skeptical argument in Kripke's book on Wittgenstein has been seriously misunderstood by recent commentators. Although it focuses particularly on recent commentary by John McDowell, it emphasizes that the basic misunderstandings are widely shared by other commentators. In particular, it argues that, properly construed, Kripke offers a fully coherent reading of PI #201 and related passages. This is commonly denied, and given as a reason for rejecting Kripke's reading of Wittgenstein's text. (...) Second, it is pretty universally accepted that Kripke's Wittgenstein is a `non-factualist' about ascriptions of meaning. The article argues that, when Kripke's discussion is rightly understood and the content of `non-factualism' is clarified, there is an important sense in which the skeptical solution is not committed to non-factualism. (shrink)

Kripke’s Wittgenstein is standardly understood as a non-factualist about meaning ascription. Non-factualism about meaning ascription is the idea that sentences like “Joe means addition by ‘plus’” are not used to state facts about the world. Byrne and Kusch have argued that Kripke’s Wittgenstein is not a non-factualist about meaning ascription. They are aware that their interpretation is non-standard, but cite arguments from Boghossian and Wright to support their view. Boghossian argues that non-factualism about meaning ascription is incompatible with a deflationary (...) theory of truth. Wright argues that non-factualism about meaning ascription is incoherent. To support the standard interpretation, I’ll respond to each argument in turn. To the degree that my responses are successful, Byrne and Kusch have an unmotivated interpretation of Kripke’s Wittgenstein. Wilson provides a factualist interpretation that is not based on Boghossian and Wright’s arguments. Miller argues for a non-factualist interpretation against Wilson, but I’ll show that Miller’s interpretation faces a dilemma. Miller’s argument cannot be maintained if a coherent interpretation of the skeptical solution is to be provided. I’ll show how this dilemma can be avoided and provide an independent argument against Wilson so that a non-factualist interpretation of the skeptical solution can be maintained. (shrink)

Semantic antirealists such as Dummett read Wittgenstein as endorsing the view that we must reject a truth conditional account of meaning in favor of one based on assertibility conditions. I take issue with that interpretation: I argue that Wittgenstein held a unique account of truth which does not fit neatly into the categories of realism and antirealism and which, moreover, undermines the dichotomy between them. Wittgenstein identified truth conditions with conventions and criteria whereby we predicate "is true" of our sentences. (...) And he held that because different sentences in a language are accepted as true upon different kinds of grounds, what is meant by calling a statement "true" varies for statements within different language games. Therefore, Wittgenstein has a novel conception of truth which can be applied, across the board, to all sentences in a language; a conception which links the truth condition of a statement to the way that the statement is used. I further argue that an implication of "meaning is use" is that we should revise our project of formulating an account of truth simpliciter, and focus instead on articulating the concept of truth that emerges from our uses of the predicate "is true".

With a few notable exceptions formal semantics, as it originated from the seminal work of Richard Montague, Donald Davidson, Max Cresswell, David Lewis and others, in the late sixties and early seventies of the previous century, does not consider Wittgenstein as one of its ancestors. That honour is bestowed on Frege, Tarski, Carnap. And so it has been in later developments. Most introductions to the subject will refer to Frege and Tarski (Carnap less frequently) —in addition to the pioneers (...) just mentioned, of course— , and discuss the main elements of their work that helped shape formal semantics in some detail. But Wittgenstein is conspicuously absent whenever the history of the subject is mentioned (usually briefly, if at all). Of course, if one thinks of Wittgenstein’s later work, this is obvious: nothing, it seems, could be more antithetic to what formal semantics aims for and to how it pursues those aims than the views on meaning and language that Wittgenstein expounds in, e.g., Philosophical Investigations, with its insistence on particularity and diversity, and its rejection of explanation and formal modelling. But what about his earlier work, the Tractatus (henceforth )? At first sight, that seems much more congenial, as it develops a conception of language and meaning that is both general and uniform, explanatory.. (shrink)

This paper argues that there are three reasons why we should regard Wittgenstein's Tractatus as a forerunner of formal semantics: Wittgenstein is convinced that we can apply formal notions to natur...

R.C. Pradhan claims in Language, Reality, and Transcendence that, in Ludwig Wittgenstein’s Tractatus Logico-Philosophicus and Philosophical Investigations, “[i]n no case is Wittgenstein interested in the empirical facts regarding language, as for him philosophy does not undertake any scientific study of language” (Pradhan 2009, xiv). I consider Ludwig Wittgenstein’s purportedly anti-scientific and anti-empirical approach to language in light of advances by philosophers and linguists in the latter half of the 20th century. I distinguish between various ways of understanding Wittgenstein’s stance against (...) scientism. Due to the success of more recent work on language, I argue that Wittgenstein’s critique, as interpreted by Pradhan in Language, Reality, and Transcendence, does not undermine the formal study of language. Nevertheless, I argue, the contention of Wittgenstein and Pradhan that language, through grammar (in Wittgenstein’s sense), serves a variety of functions still sheds light on the differences in meaning across different discourses. I argue that a synthesis of Wittgenstein’s pluralist theory of meaning with elements of a theoretical study of language offers the best comprehensive account of natural language. I will argue that this conception of language is consistent with elements of Pradhan’s interpretation. As Pradhan notes, “The aim here is not to project one kind of grammatical determination but keep options open for many such grammatical determinations such that the grammatical nuances are not papered over in the name of the unity of grammar” (Pradhan 2009, 28).

This paper discusses a number of methodological issues with mainstream formal semantics and then investigates whetherWittgenstein’s later work provides an alternative approach that is able to avoid these issues.

Wittgenstein asks: “Now what do the words of this language signify?—What is supposed to shew what they signify, if not the kind of use they have?” Might one answer that rhetorical question by giving a compositional semantics for Wittgenstein’s builder language?

Semantic contextualism is a view about the meanings of utterances. The relevant notion of meaning is that of what is said by an utterance, as it is sometimes put, of the content of the utterance. Semantic contextualism (which I will henceforth simply label “contextualism”) holds that the content of an utterance is shaped in far-reaching and unobvious ways by the circumstances, the context, in which it is uttered. Two utterances of the same sentence might vary in content as a result (...) of differences in their respective contexts that do not map onto any obvious indexical elements in the sentence. (shrink)

This book assesses the respective prospects of two competing methodological approaches to the study of meaning and communication, as well as truth and inference, each figuring prominently within the analytic tradition of philosophy of language. It defends the later Wittgenstein’s "phenomenological" methodological approach, over the "logistical" methodological approach characteristic of the early analytic philosophers.

The paper presents a formal explication of the early Wittgenstein's views on ontology, the syntax and semantics of an ideal logical language, and the propositional attitudes. It will be shown that Wittgenstein gave a "language of thought" analysis of propositional attitude ascriptions, and that his ontological views imply that such ascriptions are truth-functions of (and supervenient upon) elementary sentences. Finally, an axiomatization of a quantified doxastic modal logic corresponding to Tractarian semantics will be given.

The purpose of this dissertation is to clarify the relationship between two traditions within analytic philosophy: the epistemologically-centered philosophy exemplified by C. I. Lewis and other logical empiricists; and the semantically-generated philosophy which derives from certain views of Frege and Russell and which is exemplified in Wittgenstein's Tractatus. Logical empiricists generate their views by pursuing concerns with justification and evidence; the early Wittgenstein generates his views by pursuing concerns with the nature of language. I argue, however, that although they develop (...) their views by pursuing wholly different, and perhaps apparently unrelated, initial concerns, the early Wittgenstein and logical empiricists arrive at conflicting, and not merely unrelated, philosophical positions. ;In particular, I argue that solely by accepting certain basic views of the nature of language, each of which either Frege or Russell accepts, Wittgenstein is led in his Tractatus to reject certain views--including views of the issue of scepticism and of the nature of sense-experience--which logical empiricists generate through their concerns with justification. In doing so, I seek not only to clarify the Tractatus as well as logical empiricism, but also to show that accepting either of these positions requires rejecting the other. ;I conclude by arguing that understanding the relationship between the Tractatus and logical empiricism helps to clarify the work of Donald Davidson, a recent philosopher who rejects logical empiricism. As opposed to certain other commentators , I argue that Davidson is best understood as rejecting logical empiricism, not because he somehow rejects traditional philosophy altogether, but rather because he pursues the same sorts of philosophical concerns with the nature of language which preoccupy the early Wittgenstein.

Saul Kripke's influential ‘sceptical paradox’ of semantic rule-following alleges that speakers cannot have any justification for using a word one way rather than another. If it is correct, there can be no such thing as meaning anything by a word. I argue that the paradox fails to undermine meaning. Kripke never adequately motivates its excessively strict standard for the justified use of words. The paradox lacks the resources to show that its standard is truly mandatory or that speakers do not (...) frequently satisfy the well-motivated competitor I offer. So the paradox fails. (shrink)

Wittgenstein’s Tractatus contains some very striking theses. We read, e.g., that „in a sense” we could not be wrong in logic, and that the whole subject matter of the theory of modalities could be reconstructed on the ground of the insights in the mechanism of the linguistic reference. Yet in the light of the last sentences of Tractatus the whole semantics turns out to be principaly ineffable. In our paper we will try to clarify these matters. We show how (...) these theses could be made plausible in the context of the transcendental method of Wittgenstein’s Tractatus. (shrink)

In this reflection I address one of the critical questions this monograph is about: How to justify proposing yet another semantic theory in the light of Wittgenstein’s strong warnings against it. I see two clear motives for Wittgenstein’s semantic nihilism. The first one is the view that philosophical problems arise from postulating hypothetical entities such as “meanings”. To dissolve the philosophical problems rather than create new ones, Wittgenstein suggests substituting “meaning” with “use” and avoiding scientism in philosophy together with the (...) urge to penetrate in one's investigation to unobservable depths. I believe this first motive constitutes only a weak motive for Wittgenstein’s quietism, because there are substantial differences between empirical theories in natural sciences and semantic theories in philosophy that leave Wittgenstein’s assimilation of both open to criticism. But Wittgenstein is right, on the second motive, that given the dynamic character of linguistic practice, the classical project of semantic theory is a disease that can be removed or ameliorated only by heeding the advice to replace concern with meaning by concern with use. On my view, this does not preclude, however, a different kind of theoretical approach to meaning that avoids the pitfalls of the Procrustean enterprise Wittgenstein complained about. (shrink)

Wittgenstein's Tractatus [6] contains some very striking theses. We read, e.g., that \in a sense" we could not be wrong in logic, and that the whole subject matter of the theory of modalities could be reconstructed on the ground of the insights in the mechanism of the linguistic reference. Yet in the light of the last sentences of Tractatus the whole semantics turns out to be principally ineffable. In our paper we will try to clarify these matters. We show (...) how these theses could be made plausible in the context of the transcendental method of Wittgenstein's Tractatus. (shrink)

The aim of this paper is to compare two approaches to semantics, namely the standard Tarskian theory and Wittgenstein’s picture theory of meaning. I will compare them with respect to an unusual subject matter, namely to geometrical pictures. The choice of geometry rather than arithmetic or set theory as the basis, on which this comparison will be made has two reasons. One reason is related to Wittgenstein’s picture theory of meaning. This theory was developed more or less as a (...) metaphor, comparing the language to a picture. Nevertheless, if we take pictures themselves in the role of the language to which we apply Wittgenstein’s picture theory of meaning, this theory stops being a metaphor and starts to work in a technical way. I believe that in this way we can create a new approach to semantics in geometry. The other reason for taking geometry as the basis for our investigation is that the Tarskian approach to semantics does not work in geometry as we would wish. (shrink)

The question of "how our visual experience is related to the objects seen?" was not raised by the young Wittgenstein. It seems that at the time of writing the "Tractatus" he thought that seeing as a physically and physiologically determined act was not in need of any semantical explanation. In this essay I seek to present how Wittgenstein located the concept of "aspect-seeing" among the empirical concepts and what solution he offered for the problem of visual semantics. (edited).

After 1945, when the Philosophical Investigations were largely finished, Wittgenstein spent his final years undertaking an intensive study of the grammar of our psychological concepts and the philosophical misinterpretations we often assign to them. In the article at hand I do not claim to fathom the full range of Wittgenstein’s thoughts on the philosophy of psychology even in the most general way. Rather it is my intention to shed some light on a diagnosis which he made for the psychology of (...) his time. In Section 2 of this paper I would like to provide a brief sketch of what Wittgenstein considered to be the conceptual confusion prevalent in psychology and to suggest why he did not expect the methods of an experimental science to be successful in solving the problems that concern us in psychology. In Section 3 I’ll attempt to analyze how psychological concepts, according to Wittgenstein, might be construed in order to avoid any type of conceptual confusion. (shrink)

In 2000 the Wittgenstein Archives at the University of Bergen (WAB) published the CD-ROM edition of Wittgenstein’s Nachlass: The Bergen Electronic Edition (BEE). Moreover, since then WAB has worked towards complementing the static CD-ROM edition with an interactive web platform that additionally allows more user-specific and more user-tailored utilizations of WAB’s Nachlass resources. The paper describes two specific web service tools of this platform: Interactive Dynamic Presentation (IDP) of the Wittgenstein Nachlass and Semantic Faceted Search and Browsing (SFB) of Wittgenstein (...) domain metadata. The paper argues that it is only when these two tools are fully implemented and functional that WAB can adequately serve the scholarly needs of the Wittgenstein Nachlass user community. The paper discusses some selected features and functionalities of the two tools in detail. An earlier version of this paper was published as „Complementing Static Scholarly Editions with Dynamic Research Platforms: Interactive Dynamic Presentation (IDP) and Semantic Faceted Search and Browsing (SFB) for the Wittgenstein Nachlass“ in Selected Papers from the CLARIN Annual Conference 2020, ed. by C. Navarretta & M. Eskevich (Utrecht: CLARIN ERIC). In writing this paper I have benefitted from comments by K. De Smedt, N. Gangopadhyay, Ø. Gjesdal, J. Hendrickson, C. Huitfeldt, H.
