ABSTRACT={This paper aims at presenting a logical framework capable of expressing epistemological contextualism. Epistemological contextualism relies upon the possibility of an indexical interpretation of the knowledge operator, according to which the truth conditions of knowledge attributions exhibit a contextual variability in such a way that knowledge in one context does not entail knowledge in every context. By means of a notion of epistemic context defined on the basis of the notion of context developed by McCarthy and Buvaˇc in artificial intelligence, I show how an indexical interpretation of the knowledge operator can be formally modeled through a natural deduction system that enables classical reasoning among contexts governed by different concepts of knowledge.}}
