Frege on judgement and the judging agent

Abstract

How is Frege able to claim that the notion of judgement is essential to his logic without introducing a form of psychologism? I argue first that Frege's logical notion of judgement is to be distinguished from an empirical notion of judgement, that it cannot be understood as an abstract, idealized notion, and that there are doubts concerning a transcendental reading of Frege's writings. Then, I explain that the logical notion of judgement has to be understood from a first-person perspective, to be contrasted with a third-person perspective, in which judgement is understood as an empirical, psychological phenomenon. Frege's logic is essentially a firstperson engagement, as each of us can make use of the ideography as a science of logic only if we ourselves have made the relevant judgements. Finally, I claim that the judging agent as conceived by Frege can, after all, be understood as a transcendental ego.
