In conversations with Schlick and Waismann from June and December 1930, Wittgenstein began to turn his attention to the topic of games. This topic also centrally concerned Schlick. In his earliest philosophical output, Schlick had relied on the results of evolutionary biology in setting out an account of the emergence of the human species’ ability to play [Spiel] as a prerequisite for the genesis of scientific knowledge. Throughout his subsequent works one finds fragmentary appeals to this early view, e.g. in (...) his oft misunderstood claim that play constitutes the meaning of life. Wittgenstein’s turn to the topic of games in 1930 not only happened while Professor Schlick was in the room, but was also coupled with an explicit response to Schlick’s 1930 book Fragen der Ethik. Schlick here employs the example of chess to distinguish between rules and their application – a distinction which underlies his whole attempt to naturalise ethics as a descriptive psycho-sociological discipline. This paper investigates the relation between Wittgenstein’s and Schlick’s accounts of games in light of Wittgenstein’s criticisms of Schlick’s ethics. Wittgenstein’s objections can be answered by taking Schlick’s theory of play into consideration. (shrink)

The relationship between Carnap’s Logical Syntax of Language and Wittgenstein’s Tractatus Logico-Philosophicus has been interpreted in several ways during past decades. One of the interpretations has gained keen advocates among Carnap scholars. It was originally provoked by what Caranp said in LSL, and it consists of two parts. First, it indicates that in TLP the possibility of speaking about the logical form of a language within the same language had been foresworn by Wittgenstein, but Carnap proved him wrong by producing (...) a book written exactly in the manner which had been proscribed by Wittgenstein. This is the debate about the possibility of speaking about logical form. Second, Wittgenstein’s dogmatism with regard to the existence of a unique correct grammar at the foundation of the language has been contrasted with Carnap’s open-mindedness in conceiving a boundless ocean of possibilities for constructing logical systems. Interestingly enough, Wittgenstein rambled with rage in reaction to Carnap’s view about the LSL-TLP relationship. But unlike Carnap’s view, which led to a dominant interpretation of the relationship, Wittgenstein’s testimony about the case has been strangely ignored in the history of analytic philosophy. In this paper, I try to make an inquiry about the grounds for Wittgenstein’s dissatisfaction with the Carnapian reading of the LSL-TLP relationship. I will show that Wittgenstein was not totally unfair in his judgment, and that some salient aspects of LSL could be best understood in the light, or rather the gloom, of TLP, and bear a significant resemblance to it. This, however, does not need to diminish the logical and historical significance of LSL. (shrink)

It is a commonplace of the history of analytic philosophy that Carnap swiftly adopted Tarskian semantics in the mid-1930s. There is no doubt that, in a very general sense, this is true. But to what extent are the innovative technical details characteristic of Tarski's method, specifically the handling of quantification by way of a satisfaction relation between formulas and variable assignments, reflected in Carnap's writings on semantics? Curiously enough, their essentials are in place just before Carnap took the purported Tarskian (...) turn, namely in the definition of analyticity he formulated some time between September 1932 and April 1933, but are missing from his publications on semantics after 1935 until the final chapter of Meaning and Necessity of 1947, at which point we find Carnap reverting to the use of specifically Tarskian techniques in the context of his novel semantics for quantified modal languages.

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)

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)
