1. Complex demonstratives (noun phrases of the form ‘that F’) often behave in devious ways which do not fit well with their traditional understanding as devices of direct reference. Namely, there a...

In this review I provide a brief analysis of the main features of the collective volume Shifting Concepts (Oxford University Press, 2020), edited by Teresa Marques and Åsa Wikforss. The volume addresses several related topics, and it contains contributions from psychologists and philosophers. It deals with the topic of concept variation understood in a broad sense, for it tackles diachronic, contextual, interpersonal and even intrapersonal variation; besides, the second part of the book is devoted to the topic of concept revision (...) and amelioration. I provide a brief description of the book and then I critically assess each of the contributions. (shrink)

Semanticists often restrict their theories by imposing constraints on the parameters that can be employed for interpreting the expressions of a language. Such constraints are based on non-logical features of actual contexts of utterance, but they often have important effects on issues that do pertain to logic, like analyticity or entailment. For example, Kaplan’s restriction to so-called “proper contexts” was required in order to count “I am here now” as valid. In this paper I argue that constraints of this kind (...) are often posited in an arbitrary and non-consistent way, and that they yield the intended results only at the price of imposing ad hoc principles whose justification could in turn justify further, often undesirable restrictions into the theory. I also introduce a criterion for telling whether such constraints are imposed in a legitimate manner. (shrink)

In this paper I defend two claims regarding complex demonstratives. On the one hand I argue that, when one of these expressions misdescribes the referred object, the right semantic analysis is to treat the expression as uninterpretable. On the other, I claim that the uninterpretability thesis finds itself in trouble when it comes to dealing with non-deictic uses of complex demonstratives, i.e., uses of “that F” in which the speaker has no acquaintance or direct perception of any object that could (...) satisfy the predicative material. In order to make these two claims compatible, I set out to modify the way the uninterpretability thesis has been traditionally formulated. (shrink)
