Over the last decade or so, there has been a renewed interest in a view about properties known as quidditism. However, a review of the literature reveals that ‘quidditism’ is used to cover a range of distinct views. In this paper I explore the logical space of distinct types of quidditism. The first distinction noted is between quidditism as a thesis explicitly about property individuation and quidditism as a principle of unrestricted property recombination. The distinction recently drawn by Dustin Locke between extravagant quidditism and austere quidditism is a distinction between quidditisms of the first type. It is then argued that austere quidditism may itself be further sub-divided into what I call ‘extremely austere quidditism’ and ‘moderately austere quidditism’. Moderately austere quidditism is argued to be preferable to extremely austere quidditism and further to be able to address many of the arguments leveled against quidditism in general.

Crispin Wright has argued that truth and warranted assertibility are coincident but non-co-extensive norms of assertoric practice and that this fact tends to inflate deflationary theories of truth. Wright’s inflationary argument has generated much discussion in the literature. By contrast, relatively little has been said about the claim that truth and warranted assertibility are coincident norms. This paper will examine that claim. Wright’s argument for the claim that truth and warranted assertibility are coincident norms is first clearly presented. It is then suggested that the argument trades on an ambiguity in ‘justified’ and ‘warrantedly assertible’. Finally, it is argued that, once the ambiguity is removed, there is reason to reject the claim that truth and epistemic warrant are coincident norms of assertoric practice. One important result is that no epistemic theory of truth can satisfy what Wright takes to be a platitude about assertion.
