This short book comprises “four largely self-contained studies … unified by a common interpretive approach”, the “investigation of the historical development of … Wittgenstein’s early philosophy”. Proops applies this historical approach to Wittgenstein’s conception of logic, his critique of “logical assertion,” his “picture theory” of language, and his discussion of the justification of deduction. He endeavors to “bring out how Wittgenstein develops his views … as foils to the positions developed by Frege and Russell”, arguing that “it is not Frege (...) but Russell whose work provides the most important background for … the Tractatus”.

In her Introduction to Wittgenstein’s Tractatus , Elizabeth Anscombe took it to be a fault of the Tractatus that it excluded the statement “‘Someone’ is not the name of someone”, which she took to be obviously true. It is not a bipolar proposition, and its negation, she said, peters out into nothingness. I examine the question whether she is right that the Tractatus excludes such propositions, and I consider her example in relation to other propositions which, arguably at least, have (...) no intelligible negation. In considering the particular case of Frege’s response to Benno Kerry about the concept ‘horse’, I try to develop an account of the place in Wittgenstein’s philosophy for certain sorts of proposition which do not have an intelligible negation.

The first section of this paper introduces talk about absolutely everything -- the world as a totality -- as an integral element in the project of natural theology, as it has been presented by Fergus Kerr and Denys Turner respectively. The following section presents talk about the world as a totality of facts as a theme in philosophical logic and outlines a problem it has given rise to there. After confronting the solution originally suggested by Bertrand Russell and defended by (...) David Armstrong, the paper points to key elements of the solution presented by Wittgenstein in Tractatus Logico-Philosophicus. I show how Wittgenstein’s answer to the question of unrestricted quantification draws on his notion of showing and the inexpressible. Against this background, the concluding section draws attention to an important difference in ambition between Kerr’s and Turner’s description of the prospects for natural theology. (shrink)

In this paper, I present a summary of the philosophical relationship betweenWittgenstein and Brouwer, taking as my point of departure Brouwer's lecture onMarch 10, 1928 in Vienna. I argue that Wittgenstein having at that stage not doneserious philosophical work for years, if one is to understand the impact of thatlecture on him, it is better to compare its content with the remarks on logics andmathematics in the Tractactus. I thus show that Wittgenstein's position, in theTractactus, was already quite close to (...) Brouwer's and that the points of divergence are the basis to Wittgenstein's later criticisms of intuitionism. Among the topics of comparison are the role of intuition in mathematics, rule following, choice sequences, the Law of Excluded Middle, and the primacy of arithmetic over logic. (shrink)

Wittgenstein is not primarily concerned with anything mysterious going on inside people's heads, but with us simply going on with each other; that is, with us being able to inter-relate our everyday, bodily activities in unproblematic ways in with those of others, in practice. Learning to communicate with clear and unequivocal meanings; to send messages; to fully understand each other; to be able to reach out, so to speak, from within language-game entwined forms of life, and to talk in theoretical (...) terms of the contacts one has made., as an individual, with what is out there; and so on — all these abilities are, or can be, later developments. Wittgenstein's investigations into our pre-individual, pre-theoretical, embodied, compulsive activities are utterly revolutionary. They open up a vast new realm for empirical study to do with the detailed and subtle nature of the bodily activities in the background to everything that we do. The relational character of such pre-theoretical, Ur-linguistic, spontaneous bodily activities—and the way in which they display us as seeing connections from within a synopsis of trivialities — is explored through the paradigm of currently fashionable 3–13 random dot autostereograms.

Wittgenstein siempre practicó la filosofía como una actividad esclarecedora de las condiciones conceptuales del significado lingüístico. En la primera parte del artículo se trata de probar el papel relevante que Wittgenstein dio al uso de modelos como método de análisis del funcionamiento del lenguaje. Asimismo, en la parte final se intenta mostrar la dimensión ética y la significación estética que Wittgenstein atribuyó a su labor filosófica de aclaración. For Wittgenstein, the philosophical working was an enlightening tool in order to disclose (...) the conceptual conditions of the linguistic meaning. The aim of the first part of the paper is to show the relevant role that Wittgenstein gave to models in his description of the way in which our language works. The last part emphasizes both the ethical dimension and the aesthetic significance that Wittgenstein attached to his philosophical work of clarification. (shrink)

Various theories suggest conscious phenomena are based exclusively on brain activity, while others regard them as a result of the interaction between embodied agents and their environment. In this paper, I will consider whether this divergence entails the acceptance of the fact that different theories can be applied in different scales (as in the case of physics), or if they are reconcilable. I will suggest that investigating how the term representation is used can reveal some hints, building upon which we (...) can bridge the gulf between the two poles in the long run. In my argumentation I will rely on some earlier philosophical insights, such as those of Descartes, James, Wittgenstein and Merleau-Ponty, as well as research based on global workspace theory, and the conceptions of embodied and enacted cognition. I will suggest that within a wider horizon of investigation, the ambiguity as regards the term representation will decrease. (shrink)

In his writings Philosophical Remarks, the Austrian-British Philosopher Ludwig Wittgenstein draws an octahedron with the words of pure colours such as “white”, “red” and “blue” at the corners and argues: “The colour octahedron is grammar, since it says that you can speak of a reddish blue but not of a reddish green, etc”. He uses the word “grammar” in such a specific way that the grammar or grammatical rules describe the meanings of words/expressions, in other words, how we use them (...) in our language. Accordingly, the colour octahedron can also be taken to represent grammatical rules about how we apply words of colour, e.g., that we can call a certain colour “reddish-blue”, but not “reddish-green”. In a different context, the Japanese philosopher Shūzō Kuki explores in his work The Structure of Iki what the Japanese word “iki” means. This word is often translated as “chic” or “stylistic” in English, but Kuki holds that it is an aesthetic Japanese concept that cannot be translated one-to-one, instead encompassing three aspects: “coquetry”, “pride and honour” and “resignation”. To explain the meanings of the word “iki” and other related words all of which Kuki calls “tastes”, he introduces a rectangular prism as a geometrical representation similar to Wittgenstein’s colour octahedron. In this paper, I argue that the rectangular prism does not solely explain how the modes of Japanese tastes are related to each other, but also has a grammatical character. On this score, I suggest that one can regard this rectangular prism as a description of the grammatical rules of the Japanese language. By appeal to the arguments of both philosophers and in comparison with them, I will not only clarify what they claim by geometrical representations but also examine what role this kind of representation plays as an explanation of grammar in general. Keywords: grammar, colour octahedron, rectangular prism, Shūzō Kuki, Wittgenstein. (shrink)

The idea that there are features of or in our conscious experience that are, in some important sense, private has both a long history in philosophy and a large measure of intuitive attraction. Once this idea is in place, it will be very natural to assume that one can think and judge about one’s own private features. And it is then only a small step to the idea that we might communicate such thoughts and judgements about our respective private features (...) with each other. (shrink)

The concept of übersichtliche Darstellung is of fundamental significance for Wittgenstein . Hacker translates übersichtliche Darstellung as ‘surveyable representation’ and equates it with the tabulation of grammar. He asks what surveyability means, whether examples can be found in Wittgenstein’s work, and why this method characterizes the form of account he gives. Ultimately, however, Hacker is unable to answer these questions and he attributes this failure to Wittgenstein. This paper argues that it is Hacker’s interpretation that fails, and presents an alternate (...) understanding of übersichtliche Darstellung ; one that enables us to answer Hacker’s questions in a manner consistent with Wittgenstein’s philosophical practices.

According to the received view, the Tractatus would present a realistic conception of the meaning of a declarative sentence: that meaning would be explained in terms of evidence-transcending, not epistemically-constrained, truth-conditions. In this paper, I make a case against such a contention. If states of affairs are identified with possible combinations of phenomenal objects, the truth-conditions of an elementary proposition inevitably collapse onto its assertability-conditions: the existence of the state of affairs depicted by the proposition would be both the condition (...) for its being true and, at the same time, the condition for our recognition of its being true. Moreover, the finiteness of logical space (the set of all phenomenal states of affairs) would ensure the decidability, in principle, of all meaningful propositions, and hence would preserve the general validity of the laws of classical logic. Lastly, the problem of the relationship between the overt verificationism of Wittgenstein's 1929-1933 writings and the Tractatus's ontological and semantic views, is dealt with. (shrink)

This paper focuses on the relation between logic and ontology. In particular, it demonstrates how classical logical theory can clarify the ontological part of Ludwig Wittgenstein’s Tractatus Logico-Philosophicus. To this end, the work examines the adequacy of a formal system that was devised by the Polish logician, mathematician and philosopher Roman Suszko (1919–1979) as a model for the Tractatus. Following a brief explanation of the Tractarian ontology, the main ideas of Suszko’s system and its philosophical significance will be considered. The (...) latter will be illustrated in the context of central Tractarian concepts. Finally, two implications for a better understanding of the Tractarian ontology will be pointed out. (shrink)

The article provides a summary of the author's book Understanding People: Normativity and Rationalizing Explanation (Oxford: Clarendon Press, 2004). It details three areas in which the notion of a normative commitment is made central. These are (1) believing and intending, (2) practices conceived as essentially rule-governed activities, and (3) meaning and concepts. An account is given of how we may best explain the commitments incurred by beliefs and intentions. It is held that those states are themselves essentially normative. A problem (...) of the relevance of rationalizing to rationalizing explanation is explored and the relation between normative commitments and normative reasons is discussed. (shrink)
