Epistemic Logic

Abstract

The book explores the progressive interest in the pragmatic dimension of language during the later Middle Ages, which complements the semantic and the syntactic preoccupations of earlier medieval logic. After noting an attempt to formulate an epistemic conception of "consequentia" before the mid-twelfth century by Garland and Abelard, the author offers evidence of epistemic concerns by Burley and Ockham, reviews the specialized epistemic interests, including iteration and conditions for knowing contingent propositions, among the Oxford Calculators, and then explores in detail the impact of Strode's statement of epistemic rules on the logicians teaching at north-Italian universities up to 1500.
