Abstract:

Logical pluralism is the view that there is more than one right logic. A particular version of the view, what is sometimes called domain-specific logical pluralism, has it that the right logic and connectives depend somehow on the domain of use, or context of use, or the linguistic framework. This type of view has a problem with cross-framework communication, though: it seems that all such communication turns into merely verbal disputes. If two people approach the same domain with different logics as their guide, then they may be using different connectives, and hence talking past each other. In this situation, if we think we are having a conversation about “ ¬ A”, but are using different “ ¬ ”s, then we are not really talking about the same thing. The communication problem prevents legitimate disagreements about logic, which is a bad result. In this paper I articulate a possible solution to this problem, without giving up pluralism, which requires adopting a notion of metalinguistic negotiation, and allows people to communicate and disagree across domains/contexts/frameworks.

Publisher’s Note:

In the decades following Quine, debates about existence have taken center stage in metaphysics. But neo-Quinean ontology has reached a crisis point, given the endless proliferation of positions and lack of any clear idea of how to resolve debates. The most prominent challenge to mainstream ontological debates has come from the idea that disputants can be seen as using the quantifier with different meanings, leaving the dispute merely verbal. Nearly all of the work in defense of hard ontology has gone into arguing against quantifier variance. This volume argues that hard ontology faces an entirely different challenge, which remains even if the threat of quantifier variance can be avoided. The challenge comes from the ‘easy approach to ontology’: the idea that many ontological questions can be answered by undertaking trivial inferences from uncontroversial premises, making prolonged disputes about the questions out of place. Such a view is arguably the heir to Carnap’s own position. This book aims to develop the easy approach to ontology, showing how it leads to both a first-order simple realism about the disputed entities and a form of metaontological deflationism that takes ontological disputes themselves to be misguided, since existence questions may be answered by straightforward conceptual and/or empirical work. It also aims to defend the easy approach against a range of objections and to show it to be a viable and attractive alternative to hard ontology.

Abstract:
Description: Survey article on logical pluralism. The article is divided into three main parts: i) in the first one the author presents the main arguments for logical pluralism with respect to logical consequence; ii) in the second part, the author considers the relation between logical pluralism and Carnap's linguistic pluralism; iii) in the last section, the author considers further kinds of logical pluralism.
