The purpose of this paper is to offer an interpretation of the Tractatus’ proof of the unity of logic and language. The kernel of the proof is the thesis that the sole logical constant is the general propositional form. I argue that the Grundgedanke, the existence of the sole fundamental operation N and the analyticity thesis, together with the fact that the operation NN can always be seen as having no specific formal difference between its result and its base, imply (...) that NN is intrinsic to every elementary proposition. I also argue that the picture theory of proposition is an account of the generation of propositions via naming, and that its crucial idea is that naming is the instantiation of the form of a name, which consists in arbitrarily picking out an object as the meaning of the name from those objects sorted out by the form of the name. It follows that the existential quantifier, that is, NN, is intrinsic to naming (and therefore to every elementary proposition). It is then proven that the sole logical constant is the general propositional form. This, together with the truth‐functionality of logical necessity, implies that logic and language are unified via a general rule – logical syntax. (shrink)

This paper substitutes a structural hermeneutics for the sequential approach to the Tractatus and its manuscript, which leaves the manuscript completely unexplained. All the pieces come together only if we recognise that Wittgenstein's book is a hierarchical object that was composed following a top-down strategy. Therefore, we realise that the “summary on scattered sheets” represents the perspicuous version of the manuscript, the correlations with the Notebooks become obvious and the “supplements” can be reconstructed. A correct dating of the composition allows (...) us to understand how it was possible, without digital technologies except from an ingenious application of the decimal system, to achieve this formal masterpiece.

The paper aims to make out the incoherence of the distinction between and rigid separation of ‘the linguistic’ and ‘the extra‐linguistic’ as well as to absolve Wittgenstein from any commitment to it. Insistence on a descent from the abstract to a concrete discussion allows a connection to be made between Tractatus positions such as: ‘The limits of my language indicate the limits of my world.’ and ‘The world and life are one.’ and the Investigations: ‘What has to be accepted is (...) ‐ so one could say ‐ forms of life.’ From this a picture is developed of the intimate interconnection between language, practical life, and world.

This paper focuses on a central aspect of the “picture theory” in the Tractatus – the “identity requirement” – namely the idea that a proposition represents elements in reality as combined in the same way as its elements are combined. After introducing the Tractatus' views on the nature of the proposition, I engage with a “nominalist” interpretation, according to which the Tractatus holds that relations are not named in propositions. I claim that the nominalist account can only be maintained by (...) rejecting the “identity requirement.” I then consider an opposite – “realist” – interpretation, according to which Tractarian names include names of properties and relations. I argue that, although it can accommodate the “identity requirement,” the realist interpretation falls short of providing a correct interpretation of the Tractatus' conception of a name. I conclude by presenting an alternative account (to both nominalism and realism) of the Tractatus' conception of a name. (shrink)

Abstract: Interpretations of the Tractatus divide into what might be called a metaphysical and an anti-metaphysical approach to the work. The central issue between the two interpretative approaches has generally been characterised in terms of the question whether the Tractatus is committed to the idea of ‘things’ that cannot be said in language, and thus to the idea of a distinctive kind of nonsense: nonsense that is an attempt to say what can only be shown. In this paper, I look (...) at this dispute from a different perspective, by focusing on the treatment of the concept of internal relations. By reference to the work of Peter Hacker, Hidé Ishiguro and Cora Diamond, I show how this concept is understood quite differently in each of the two interpretative traditions. I focus particularly on how Wittgenstein's idea of the ‘internal relation of depicting that holds between language and the world’ (Tractatus 4.014) might be understood within the two interpretative approaches. I offer some reasons in support of the anti-metaphysical treatment of the concept. (shrink)

The word “picture” occurs pervasively in Wittgenstein's later philosophy. Not only does Wittgenstein often use literal pictures or the notion of mental pictures in his investigations, but he also frequently uses “picture” to speak about a way of conceiving of a matter (e.g. “A picture held us captive” at Philosophical Investigations§115). I argue that “picture” used in this conceptual sense is not a shorthand for an assumption or a set of propositions but is rather an expression of conceptual bedrock on (...) the model of an organising myth. This reading builds primarily on work by Gordon Baker and Stanley Cavell. (shrink)

My essay explains and examines Anscombe's disagreement with Wittgenstein about what the Tractatus supposedly excludes. I also discuss her apparent disagreement with Geach about propositions that lack an intelligible negation. My discussion of these disagreements leads to the topic of Anscombe on the relation between the “business of thinking” and truth. I suggest that she takes the business of thinking to include thinking that helps to keep thinking on track. Since there is a tie between thinking truly and the business (...) of thinking being done well and since helping to keep thinking on track belongs to the business of thinking, helpings-of-thinking can be described as true.

So-called 'hinge propositions', Wittgenstein's version of our basic beliefs, are not propositions at all, but heuristic expressions of our bounds of sense which, as such, cannot meaningfully be said but only show themselves in what we say and do. Yet if our foundational certainty is necessarily an ineffable, enacted certainty, any challenge of it must also be enacted. Philosophical scepticism – being a mere mouthing of doubt – is impotent to unsettle a certainty whose salient conceptual feature is that it (...) is lived. I appeal to psychopathology to show that the lived refutation of a basic certainty is not a manifestation of uncertainty, but of madness. (shrink)
