In our papers on the rationality of magic, we distinghuished, for purposes of analysis, three levels of rationality. First and lowest (rationalitYl) the goal directed action of an agent with given aims and circumstances, where among his circumstances we included his knowledge and opinions. On this level the magician's treatment of illness by incantation is as rational as any traditional doctor's blood-letting or any modern one's use of anti-biotics. At the second level (rationalitY2) we add the element of rational thinking or thinking which obeys some set of explicit rules, a level which is not found in magic in general, though it is sometimes given to specific details of magical thinking within the magical thought-system. It was the late Sir Edward E. Evans-Pritchard who observed that when considering magic in detail the magician may be as consistent or critical as anyone else; but when considering magic in general, or any system of thought in general, the magician could not be critical or even comprehend the criticism. Evans-Pritchard went even further: he was sceptical as to whether it could be done in a truly consistent manner: one cannot be critical of one's own system, he thought. On this level (rationalitY2) of discussion we have explained (earlier) why we prefer to wed Evans Pritchard's view of the magician's capacity for piece-meal rationality to Sir James Frazer's view that magic in general is pseudo-rational because it lacks standards of rational thinking."

An outstanding feature of this book is the broad range of the contributors, drawn from Europe, the Middle East and North America, testifying both to the range of Professor Agassi's interests and the geographical spread of his influence. Most contributors use Agassi's ideas as a springboard to engage in debate on issues, or offer a contribution in an area that interests him. In this volume contributors consider such questions as Agassi's philosophy of education, in practice as well as in theory; the impact of psychologism in philosophy; the origins of critical rationalism in the Bible; the debates in economics stimulated by the work of Popper and Agassi, and many other topics. Besides the special topics, the reader gains some sense of the fruitfulness of critical rationalism in the hands of Agassi's friends and colleagues.

I suppose Joseph Agassi's best and dearest self-description, his cher ished wish, is to practice what his 1988 book promises: The Gentle Art of Philosophical Polemics. But for me, and for so many who know him, our Agassi is tough-minded, not tender, not so gentle. True to his beloved critical thinking, he is ever the falsificationist, testing himself of course as much as everyone else. How, he asks himself, can he engage others in their own self-critical exploration? Irritate? Question their logic, their facts, their presuppositions, their rationales? Subvert their reasoning, uncover their motives? Help them to lose their balance, but always help them, make them do it to, and for, themselves. Out of their own mouths, and minds, and imagination. A unique teacher, in classroom and out; not for everyone. Agassi is not quite a tight textual Talmudist disputant, not quite the competitor in the marketplace of ideas offered for persuasive sale, not quite the clever cross-examining lawyer advocate, not quite a philosopher-scientist, not a sceptic more than necessary, not quite embat tled in the bloody world but not ever above the battle either . . . but a good deal of all of these, and steeped in intelligence and good will."

First published in 1998. Routledge is an imprint of Taylor & Francis, an informa company.

Professor Jarvie examines the nature of the revolution in social anthropology in order to investigate its results. Working within Karl Popper's radical view of the nature of science, he argues that the subject is one of the oldest and most fundamental of all studies and suggests it can easily be traced back to Plato and Aristotle, not merely as a matter of historical curiosity, but as having fruitful results for the understanding of Malinowski and the revolution.

Anthropology revolves round answers to problems about the nature, development and unity of mankind; problems that are both philosophical and scientific. In this book, first published in 1984, Professor Jarvie applies Popper's philosophy of science to understanding the history and theory of anthropology. Jarvie describes how the ancient view that the aim of science and philosophy was to get at the truth is challenged in anthropology by the doctrine of cultural relativism; that is, that truth varies with the cultural framework. He shows how philosophers as various as Peter Winch, W.V.O. Quine, W.T. Jones, Nelson Goodman and Richard Rorty were influenced by this doctrine. Yet these philosophers also accept the value of rational argument. Jarvie believes that there is a contradiction between relativism and any notion of human rationality that centres around argument. Forced by the contradiction to choose between rationality and relativism, he argues strongly that logical, scientific and moral considerations favour rationality and urge repudiation of relativism. The central argument of the book is that relativism is intellectually disastrous and has fostered intellectual attitudes from which anthropology still suffers.

This set of essays is concerned with the explanation of large scale social change. Concentration is on the social stagnation characteristic of agrarian circumstances, the conditions for exit from that world, and the varied social orders that inhabit, sometimes precariously, the modern world community. The distinguished contributors from archaeology, anthropology, sociology, economic history and philosophy, have all been stimulated by the work of Ernest Gellner, and the essays are in dialogue with his view of our social condition.
