We show how to construct certain L M, T -type interpreted languages, with each such language containing meaningfulness and truth predicates which apply to itself. These languages are comparable in expressive power to the L T -type, truth-theoretic languages first considered by Kripke, yet each of our L M, T -type languages possesses the additional advantage that, within it, the meaninglessness of any given meaningless expression can itself be meaningfully expressed. One therefore has, for example, the object level truth (and (...) meaningfulness) of the claim that the strengthened Liar is meaningless. (shrink)

We show how to construct certain " $[Unrepresented Character]_{M,T}$ -type" interpreted languages, with each such language containing meaningfulness and truth predicates which apply to itself. These languages are comparable in expressive power to the $[Unrepresented Character]_{T}$ -type, truth-theoretic languages first considered by. Kripke, yet each of our $[Unrepresented Character]_{M,T}$ -type languages possesses the additional advantage that, within it, the meaninglessness of any given meaningless expression can itself be meaningfully expressed. One therefore has, for example, the object level truth (and meaningfulness) (...) of the claim that the strengthened Liar is meaningless. (shrink)

We began by distinguishing Tarskian and Fitchean notions of universality in such a way that the claim that no language is universal in the sense of Tarski is compatible with accepting Fitchean universality. Then we examined a proposal involving two truth concepts — one that fit the Fitchean notion and another that followed Tarski's views on truth — finding little advantage in such generosity. We attempted a reformulation of Herzberger's argument for the negative view — the view that no language (...) is universal in Tarski's sense — but found it unsuccessful when the language of the argument's formulation was brought under consideration. A more persuasive argument for EI was found, free of the defect of the previous one. EI was then shown to have unsettling consequences, prompting us to inquire about avoiding it. We found this possible, noting that EI is itself a solution to the semantic paradoxes, to which there are alternatives that avoid the unwelcome aspects of EI. However, whether any such alternative is ultimately preferable to EI remains to be seen. (shrink)

In this paper it is argued that herzberger's general theory of presupposition may be successfully applied to category mistakes. The study offers an alternative to thomason's supervaluation treatment of sortal presupposition and as an indirect measure of the relative merits of the two-Dimensional theory to supervaluations. Bivalent, Three-Valued matrix, And supervaluation accounts are compared to the two-Dimensional theory according to three criteria: (1) abstraction from linguistic behavior, (2) conformity of technical to preanalytic distinctions, And (3) ability to capture classical logic. (...) A matrix like characterization of thomason's theory is reported. (shrink)

This article contains an overview of the main problems, themes and theories relating to the semantic paradoxes in the twentieth century. From this historical overview I tentatively draw some lessons about the way in which the field may evolve in the next decade.
