Despite huge advances in education, knowledge and communication, it can often seem we are neither well-trained nor well-practiced in the art of clear thinking. Our powers of reasoning and argument are less confident that they should be, we frequently ignore evidence and we are all too often swayed by rhetoric rather than reason. But what can you do to think and argue better? First published in 1939 but unavailable for many years, Susan Stebbing's Thinking to Some Purpose is a classic (...) first-aid manual of how to think clearly and remains astonishingly fresh and insightful. Written against a background of the rise of dictatorships and the collapse of democracy in Europe, it is packed with useful tips and insights. Stebbing offers shrewd advice on how to think critically and clearly, how to spot illogical statements and slipshod thinking, and how to rely on reason rather than emotion. At a time when we are again faced with serious threats to democracy and freedom of thought, Stebbing's advice remains as urgent and important as ever. This Routledge edition of Thinking to Some Purpose includes a new Foreword by Nigel Warburton and a helpful Introduction by Peter West, who places Susan Stebbing's classic book in historical and philosophical context.

First published in 1943, and revised for this 1952 edition, this book was intended for use by students of philosophy and as such traditional and modern developments in logic have been combined in a unified treatment. The author envisaged this volume as filling a gap for a simple, introductory text on formal logic, written from a modern point of view, unencumbered by traditional doctrine. This title provides a thorough introduction and grounding in the philosophy of logic, and was later revised (...) after the author’s death to correct a number of logical errors — making this edition the most complete version of the work.

Originally published in 1934. This fourth edition originally published 1954., revised by C. W. K. Mundle. "It must be the desire of every reasonable person to know how to justify a contention which is of sufficient importance to be seriously questioned. The explicit formulation of the principles of sound reasoning is the concern of Logic". This book discusses the habit of sound reasoning which is acquired by consciously attending to the logical principles of sound reasoning, in order to apply them (...) to test the soundness of arguments. It isn't an introduction to logic but it encourages the practice of logic, of deciding whether reasons in argument are sound or unsound. Stress is laid upon the importance of considering language, which is a key instrument of our thinking and is imperfect. (shrink)

Originally published in 1914, this book examines the French Voluntarist school of philosophy and the key ways in which it differs from the Pragmatists. Stebbing argues that Voluntarism and Pragmatism both prove inadequate in their definition of truth, and suggests that an acknowledgment of the 'non-existential character of truth' is needed. This book will be of value to anyone with an interest in philosophy.
