In this article we revisit a number of disputes regarding significance logics---i.e., inferential frameworks capable of handling meaningless, although grammatical, sentences---that took place in a series of articles most of which appeared in the Australasian Journal of Philosophy between 1966 and 1978. These debates concern (i) the way in which logical consequence ought to be approached in the context of a significance logic, and (ii) the way in which the logical vocabulary has to be modified (either by restricting some notions, (...) or by adding some vocabulary) to keep as much of Classical Logic as possible. Our aim is to show that the divisions arising from these disputes can be dissolved in the context of a novel and intuitive proposal that we put forward. (shrink)

Category mistakes are sentences such as ‘Colourless green ideas sleep furiously’ or ‘The theory of relativity is eating breakfast’. Such sentences are highly anomalous, and this has led a large number of linguists and philosophers to conclude that they are meaningless (call this ‘the meaninglessness view’). In this paper I argue that the meaninglessness view is incorrect and category mistakes are meaningful. I provide four arguments against the meaninglessness view: in Sect. 2, an argument concerning compositionality with respect to category (...) mistakes; in Sect. 3 an argument concerning synonymy facts of category mistakes; in Sect. 4 concerning embeddings of category mistakes in propositional attitude ascriptions; and in Sect. 5 concerning the uses of category mistakes in metaphors. Having presented these arguments, in Sect. 6 I briefly discuss some of the positive motivations for accepting the meaninglessness view and argue that they are unconvincing. I conclude that the meaninglessness view ought to be rejected. (shrink)

This thesis focuses on 'New' or 'Resolute' readings of Wittgenstein's work, early and later, as presented in the work of, for instance, Cora Diamond and James Conant. One of the principal claims of such readings is that, throughout his life, Wittgenstein held an 'austere' view of nonsense. That view has both a trivial and a non-trivial aspect. The trivial aspect is that any string of signs could, by appropriate assignment, be given a meaning, and hence that, if such a string (...) is nonsense, that will be because we have failed to make just such an assignment. The non-trivial aspect is this: that there is no further, non-trivial story to be told, and so nonsense is only ever a matter of our failure to give signs a meaning. Hence, too, logically speaking, all nonsense is on a par. That view, both of nonsense and of Wittgenstein, has attracted a great deal of controversy. It is particularly controversial in relation to Wittgenstein's 'Tractatus', where Wittgenstein famously declares, in the penultimate remark, that the reader is to recognise Wittgenstein's own elucidatory propositions there as nonsensical, and must eventually throw them away in coming to understand Wittgenstein himself. I defend the austere view and its attribution to Wittgenstein, early and later, against a number of exegetical and substantial criticisms put forward by, for instance, Peter Hacker, Hans-Johann Glock and Adrian Moore.
