Epistemic logic is one of the most exciting areas in medieval philosophy. Neglected almost entirely after the end of the Middle Ages, it has been rediscovered by philosophers of the twentieth century. Epistemic Logic in the Later Middle Ages provides the first comprehensive study of the subject. Ivan Boh explores the contrast between epistemic and alethic conceptions of consequence, the general epistemic rules of consequence, the search for conditions of knowing contingent propositions, the problems of substitutivity in intentional contexts, the (...) considerations of epistemic/doxastic iterated modalities, and the problems of composite and divided senses in authors ranging from Abelard to Frachantian. Boh concludes with a comparison between medieval endeavors and the epistemic logic of our own times. Written in a clear and readable style with minimal symbolic apparatus, this book employs modern symbolism and conceptual frameworks, and complements the studies of the syntacticand semantic dimensions of medieval logic.

_Epistemic Logic_ studies statements containing verbs such as 'know' and 'wish'. It is one of the most exciting areas in medieval philosophy. Neglected almost entirely after the end of the Middle Ages, it has been rediscovered by philosophers of the present century. This is the first comprehensive study of the subject. Ivan Boh explores the rules for entailment between epistemic statements, the search for the conditions of knowing contingent propositions, the problems of substitutivity in intentional contexts, the relationship between epistemic (...) and modal logic, and the problems of composite and divided senses in authors ranging from Abelard to Frachantian.

In two respects this edition of Kilvington's Sophismata is a major event in the study of medieval philosophy. First, this important work throws light on the special logico-analytic character of the intellectual enterprise of Oxford Calculatores, who are justifiably credited with advancing natural philosophy and mathematics. Secondly, it contributes to the recent efforts to trace the development of medieval formal disputation, the obligatio, from the "old response" represented by Sherwood, Burley, and Ockham, to the "new response" espoused by Richard Swyneshed, (...) Lavenham, Fland, and others. (shrink)

The lead-question of Hülsen's investigation is stated in his introduction: What is the role of those pronouns which are used not demonstratively but anaphorically, that is, in relation to, or in dependence on, another expression? For example, "Socrates is old, and he is wise"; "A man is old, and he is wise." The author considers in detail three possibilities: such pronouns are convenient devices to spare us a repetition of the antecedent expression; such pronouns are basically a means for building (...) predicates, as variables in modern logic; they can be referring in relation to objects signified by their antecedents.

In the Aristotelian tradition, some propostitions need no further evidencce to be proved: they are "per se nota". This work discusses the conditions that make a proposition "per se noat" according to Thomas Aquinas, focussing on the historical background and the philosophical context of Aquinas' position.
