"A delightful book … I should like to have written it myself." — Bertrand Russell First published in 1936, this first full-length presentation in English of the Logical Positivism of Carnap, Neurath, and others has gone through many printings to become a classic of thought and communication. It not only surveys one of the most important areas of modern thought; it also shows the confusion that arises from imperfect understanding of the uses of language. A first-rate antidote for fuzzy thought and muddled writing, this remarkable book has helped philosophers, writers, speakers, teachers, students, and general readers alike. Mr. Ayers sets up specific tests by which you can easily evaluate statements of ideas. You will also learn how to distinguish ideas that cannot be verified by experience — those expressing religious, moral, or aesthetic experience, those expounding theological or metaphysical doctrine, and those dealing with a priori truth. The basic thesis of this work is that philosophy should not squander its energies upon the unknowable, but should perform its proper function in criticism and analysis.

The Emotive Theory was theory ahead of its time, and a theory which was, perhaps understandably, misinterpreted, misrepresented, and ridiculed by its critics from the outset. In this work, the author acquaints the reader with what the original emotivists actually claimed, and enriches their claims by psychologically expanding them. He thus develops an enriched emotive theory.

If there is such a thing as essential reading in metaphysics or in philosophy of language, this is it. Ever since the publication of its original version, Naming and Necessity has had great and increasing influence. It redirected philosophical attention to neglected questions of natural and metaphysical necessity and to the connections between these and theories of reference, in particular of naming, and of identity. From a critique of the dominant tendency to assimilate names to descriptions and more generally to treat their reference as a function of their Fregean sense, surprisingly deep and widespread consequences may be drawn. The largely discredited distinction between accidental and essential properties, both of individual things (including people) and of kinds of things, is revived. So is a consequent view of science as what seeks out the essences of natural kinds. Traditional objections to such views are dealt with by sharpening distinctions between epistemic and metaphysical necessity; in particular by the startling admission of necessary a posteriori truths. From these, in particular from identity statements using rigid designators whether of things or of kinds, further remarkable consequences are drawn for the natures of things, of people, and of kinds; strong objections follow, for example to identity versions of materialism as a theory of the mind. This seminal work, to which today's thriving essentialist metaphysics largely owes its impetus, is here published with a substantial new Preface by the author.

A. J. Ayer, who died in 1989, was acknowledged as one of Britain's most distinguished philosophers. In this memorial collection of essays leading Western philosophers reflect on Ayer's place in the history of philosophy and explore aspects of his thought and teaching. The volume also includes a posthumous essay by Ayer himself: "A Defence of Empiricism." These essays are undoubtedly a fitting tribute to a major figure, but the collection is not simply retrospective; rather it looks forward to present and future developments in philosophical thought that Ayer's work has stimulated.

Formal logic provides us with a powerful set of techniques for criticizing some arguments and showing others to be valid. These techniques are relevant to all of us with an interest in being skilful and accurate reasoners. In this highly accessible book, Peter Smith presents a guide to the fundamental aims and basic elements of formal logic. He introduces the reader to the languages of propositional and predicate logic, and then develops formal systems for evaluating arguments translated into these languages, concentrating on the easily comprehensible 'tree' method. His discussion is richly illustrated with worked examples and exercises. A distinctive feature is that, alongside the formal work, there is illuminating philosophical commentary. This book will make an ideal text for a first logic course, and will provide a firm basis for further work in formal and philosophical logic.

What is knowledge? What, if anything, can we know? In Knowing and Seeing, Michael Ayers recovers the insight in the traditional distinction between knowledge and belief, according to which 'knowledge' stems from direct and perspicuous cognitive contact with ('seeing') its object, whereas 'belief' relies on 'extraneous' justification. He conducts a careful phenomenological analysis of what it is to perceive one's environment as one's environment, the result of which is not only direct realism, but recognition that in being perceptually aware of anything we are at the same time perceptually aware of how we are aware of it. Perceptual knowing comes with knowing how you know. Some other forms of knowledge are similarly direct and perspicuous, but not all; a distinction is accordingly drawn between primary and secondary knowledge, and Ayers argues that no secondary knowledge is possible without some primary knowledge. Perceptual knowledge supplies the paradigm to which other cases of knowledge are diversely analogous - hence the notorious difficulty of defining knowledge. These conclusions, supported by a detailed examination of the relations between different grammatical constructions in which 'know', 'believe' and 'see' occur, fuel extended critiques of two lines of thought influential in contemporary epistemology: John McDowell's conceptualist and intellectualist account of perceptual knowledge, and Fred Dretske's 'externalist' employment of sceptical argument. Ayers unpicks the arguments for these other views, explains the failure of recent attempts at a comprehensive definition of knowledge, explores the tight relation between knowledge and certainty, and gives an account of how 'defeasibility' should and should not be understood in epistemology.

Bill Ayers was born into privilege and is today a highly respected educator. In the late 1960s he was a young pacifist who helped to found one of the most radical political organizations in U.S. history, the Weather Underground. In a new era of antiwar activism and suppression of protest, his story, Fugitive Days, is more poignant and relevant than ever.
