9781840149814: Bertrand Russell on Modality and Logical Relevance

Synopsis

This is a study of Bertrand Russell on modality and relevance. Russell used notions of ordinary quantificational logic to define and analyze away the basic notions of modal logic. The ordinary individual and universal quantifiers are used to simulate modal notions. Literally speaking, Russell has banished modality from logic, yet functionally speaking, he has achieved an S5 modal logic based on a theory of modality. The author imputes seven S5 logics to Russell and shows that Russell states the key to his modal theory in at least nine works over a period of at least 36 years. The author then explains five modal "howlers" which Russell has been accused of, as based on misunderstandings. Russell's modal logic anticipates Carnap, Tarski, McKinsey, Almog and Etchemendy and has predecessors in Bolzano and Venn. The text's interdisciplinary argument involves both legal and philosophical scholarship.

Présentation de l'éditeur

BERTRAND RUSSELL ON MODALITY AND LOGICAL RELEVANCE - SECOND EDITION (2015). PRAISE FOR THE SECOND EDITION: "Looks like a seminal work." — Paul Nascimbene. PRAISE FOR THE FIRST EDITION (1999): "In the twenty-nine years since Russell’s death, much of the major scholarship has drawn heavily on his manuscripts and unpublished correspondence. The author shows that the published Russell is capable of new interpretations; in particular, that modal notions such as possibility have a greater place in various aspects of his logical and philosophical thought than has been previously imagined." —Ivor Grattan-Guinness, Foreword. PUBLISHED REVIEW OF THE FIRST EDITION: "Dejnožka's book is the first full-length study of modality in Russell. It is useful for its very full survey of passages in which Russell makes use of or alludes to modal notions. Dejnožka's command of Russell's huge output is indeed impressive and his utilization of it thorough...." — Nicholas Griffin, Studia Logica. PUBLISHED REVIEW OF THE FIRST EDITION: "Dejnožka's book raises a very important point in the history of formal logic. Until now the major studies on this topic have drawn heavily on the development of classical logic as standardized by Gottlob Frege and Bertrand Russell. Dejnožka challenges the reader to open his mind for a new interpretation of Russell's work, in particular that modal and relevance notions have a greater place in his philosophy of logic than has been stressed before.... "Dejnožka rightly observes that many of Russell's insights on modality are a result of his discussions with Hugh MacColl, who was indeed the first to seriously attempt to develop formal modal logic. This particularly applies to Russell's conception of a modal logic without modal operators....That is, classical logic can be used to simulate modal expressions. Thus, the notions of (logical) necessity and possibility are not 'fundamental notions'....On this basis, Dejnožka develops a higher level of modality, where the quantification scope extends to the predicates yielding what Russell calls 'fully general propositions'.... "The best studied translation method is known as the standard translation, and it is quite compatible with Dejnožka's suggestions.... "Dejnožka's book is full of material which stimulates [one] to rethink Russell's philosophy of logic and...it is greatly to the author's credit that he brings to light such a wealth of crucial issues in the history and philosophy of logic. — Shahid Rahman, History and Philosophy of Logic. BOOK DESCRIPTION: This book is the only exhaustive study of Russell on modality and logical relevance ever written. This is the second edition, revised over a period of seventeen years, and over twice as long. Russell initially rejects the possibility of a modal logic in an unpublished paper written ca. 1903-05 and read to an audience in 1905. But the very next year, he adopts the theory of modality he had rejected, and he repeats that theory in published works for many years to come. That theory, together with other texts scattered among Russell's writings, implies eight modal logics which Russell himself never expressly accepted. And Russell's express acceptance of the early Wittgenstein's theory of entailment ("following from") as truth-ground containment implies a deductive relevance logic in Russell's writings which Russell himself never expressly accepted. The book ends with a look at John Maynard Keynes and Anglo-American evidence law as the origins of Russell's theory of probability as degree of logical relevance. Thus the book is written toward the reunion of modern classical logicians with modal logicians and relevantists. Please see also my book, The Concept of Relevance and the Logic Diagram Tradition (2012). Thus I hope to have created two new fields of Russell studies. I may have created a new legal field as well: the history of logical relevance in evidence law (pages 368-500).
