Constructive knowledge and the justified true belief paradigm

Abstract

In this paper we analyze the foundations of epistemology from a constructive Brouwerian position. In particular, we consider the famous tripartite account of knowledge as justified true belief, JTB, traditionally attributed to Plato as well as counter-examples by Russell and Gettier. We show that from an intuitionistic perspective, when the constructive character of truth is taken into account, both Russell and Gettier examples no longer refute the principle that JTB yields knowledge. Moreover, we argue that JTB yields knowledge could be accepted given some natural constructivity assumptions.
