Carnap as a Beall-style logical monist

Abstract

There was a time when both Rudolf Carnap and Jc Beall were thought to be arch logical pluralists. Beall has since renounced his pluralistic views, but Carnap is still largely regarded as a pluralist. In this paper, I will show that there is good reason to think that Carnap is not a logical pluralist, at least in the way he is presented in the literature. Instead, I argue, he can be seen as a Beall-style logical monist at the meta-level, in line with the views expressed in Beall (APHI 14:1–29, 2017 and NOUS 28:30–54, 2018).
