Handbook of the history of logic Greek Indian and Arabic Logic marks the initial appearance of the multi volume Handbook of the History of Logic. Additional volumes will be published when ready rather than in strict chronological order. Soon to appear are The Rise of Modern Logic: From Leibniz to Frege. Also in preparation are Logic From Russell to G̱del The Emergence of Classical Logic Logic and the Modalities in the Twentieth Century and The Many Valued and Non Monotonic Turn in Logic. Further volumes will follow including Mediaeval and Renaissance Logic and Logic: A History of its Central. In designing the Handbook of the History of Logic the Editors have taken the view that the history of logic holds more than an antiquarian interest and that a knowledge of logics rich and sophisticated development is in various respects relevant to the research programmes of the present day. Ancient logic is no exception. The present volume attests to the distant origins of some of modern logics most important features such as can be found in the claim by the authors of the chapter on Aristotles early logic that from its infancy the theory of the syllogism is an example of an intuitionistic non monotonic relevantly paraconsistent logic. Similarly in addition to its comparative earliness what is striking about the best of the Megarian and Stoic traditions is their sophistication and originality. Logic is an indispensably important pivot of the Western intellectual tradition. But as the chapters on Indian and Arabic logic make clear logics parentage extends more widely than any direct line from the Greek city states. It is hardly surprising therefore that for centuries logic has been an unfetteredly international enterprise whose research programmes reach to every corner of the learned world. Like its companion volumes Greek Indian and Arabic Logic is the result of a design that gives to its distinguished authors as much space as would be needed to produce highly authoritative chapters rich in detail and interpretative reach. The aim of the Editors is to have placed before the relevant intellectual communities a research tool of indispensable value. Together with the other volumes Greek Indian and Arabic Logic will be essential reading for everyone with a curiosity about logics long development especially researchers graduate and senior undergraduate students in logic in all its forms argumentation theory AI and computer science cognitive psychology and neuroscience linguistics forensics philosophy and the history of philosophy and the history of ideas
