As one of Karl Popper's most wide-ranging and popular works, Conjectures and Refutations provides the clearest statement of the fundamental idea that guided his work: that our knowledge grows by an unending process of trial and error.

Traditional philosophical accounts of the scientific enterprise represent it as a paradigm of institutionalized rationality. The scientist is held to possess a special method which he disinterestedly applied, generating an accumulation of scientific knowledge about the world, and the evolution of science is seen as being determined by the rational deliberations of scientists and not by psychological or sociological factors. More recently, various philosophers, historians and sociologists of science have held that this rational model is no longer tenable. Some have claimed that there is no such thing as a scientific method or scientific progress, and that theories are incommensurable and so there is no possibility of choice between alternative theories. The more extreme non-rationalists seek to explain scientific change exclusively in terms of psychological and sociological factors. In this book, the author explores the controversy between the two approaches and presents a strongly critical and independent view of both rationalists like Popper and Lakatos and non-rationalists such as Kuhn and Feyerabend. He goes on to develop his own account of the scientific enterprise--temperate rationalism, a vindication of the rationalist approach to science and of a realist construal of theories.--

Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work: not only our knowledge, but our aims and our standards, grow through an unending process of trial and error.

This volume comprises original articles by leading authors – from philosophy as well as sociology – in the debate around relativism in the sociology of (scientific) knowledge. Its aim has been to bring together several threads from the relevant disciplines and to cover the discussion from historical and systematic points of view. Among the contributors are Maria Baghramian, Barry Barnes, Martin Endreß, Hubert Knoblauch, Richard Schantz and Harvey Siegel.

In a career spanning sixty years, Sir Karl Popper has made some of the most important contributions to the twentieth century discussion of science and rationality. The Myth of the Framework is a new collection of some of Popper's most important material on this subject. Sir Karl discusses such issues as the aims of science, the role that it plays in our civilization, the moral responsibility of the scientist, the structure of history, and the perennial choice between reason and revolution. In doing so, he attacks intellectual fashions (like positivism) that exagerrate what science and rationality have done, as well as intellectual fashions (like relativism) that denigrate what science and rationality can do. Scientific knowledge, according to Popper, is one of the most rational and creative of human achievements, but it is also inherently fallible and subject to revision. In place of intellectual fashions, Popper offers his own critical rationalism - a view that he regards both as a theory of knowlege and as an attitude towards human life, human morals and democracy.

"A book that shakes philosophy of science to its roots. Laudan both destroys and creates. With detailed, scathing criticisms, he attacks the 'pregnant confusions' in extant philosophies of science. The progress they espouse derives from strictly empirical criteria, he complains, and this clashes with historical evidence. Accordingly, Laudan constructs a remedy from historical examples that involves nothing less than the redefinition of scientific rationality and progress . . . Surprisingly, after this reshuffling, science still looks like a noble-and progressive-enterprise ... The glory of Laudan's system is that it preserves scientific rationality and progress in the presence of social influence. We can admit extra-scientific influences without lapsing into complete relativism. . . a must for both observers and practitioners of science." --Physics Today "A critique and substantial revision of the historic theories of scientific rationality and progress (Popper, Kuhn, Lakatos, Feyerabend, etc.). Laudan focuses on contextual problem solving effectiveness (carefully defined) as a criterion for progress, and expands the notion of 'paradigm' to a 'research tradition,' thus providing a meta-empirical basis for the commensurability of competing theories. From this perspective, Laudan suggests revised programs for history and philosophy of science, the history of ideas, and the sociology of science. A superb work, closely argued, clearly written, and extensively annotated, this book will become a widely required text in intermediate courses."--Choice

Rectifying misrepresentations of Popperian thought with a historical approach to Popper’s philosophy, Gattei reconstructs the logic of Popper’s development to show how one problem and its tentative solution led to a new problem.
