Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

Shearmur draws on his years as Popper's assistant, on unpublished material in the Hoover archive, and on wider themes within Popper's philosophy to offer striking critical re-interpretations of his ethical and social theory.

Theories of explanation in the social sciences vacillate between holism and individualism. This book contends that this has been a consequence of theories of rationality which assume that rationality requires coherent theories to be shown to be true. It claims that traditional explanations place unrealistic demands on individuals and institutions.

First published in 1986. Routledge is an imprint of Taylor & Francis, an informa company.

On its publication in 1957, _The Poverty of Historicism_ was hailed by Arthur Koestler as 'probably the only book published this year which will outlive the century.' A devastating criticism of fixed and predictable laws in history, Popper dedicated the book to all those 'who fell victim to the fascist and communist belief in Inexorable Laws of Historical Destiny.' Short and beautifully written, it has inspired generations of readers, intellectuals and policy makers. One of the most important books on the (...) social sciences since the Second World War, it is a searing insight into the ideas of this great thinker. (shrink)

David Miller is the foremost exponent of the purist critical rationalist doctrine and here presents his mature views, discussing the role that logic and argument play in the growth of knowledge, criticizing the common understanding of argument as an instrument of justification, persuasion or discovery and instead advocating the critical rationalist view that only criticism matters. Miller patiently and thoroughly undoes the damage done by those writers who attack critical rationalism by invoking the sterile mythology of induction and justification that (...) it seeks to sweep away. In addition his new material on the debate on verisimilitude is essential reading for all working in this field. (shrink)

This classic remains 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.

_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 paper provides a rationale for advocating pancritical rationalism. First, it argues that the advocate of critical rationalism may accept (but not be internally justified in accepting) that there is ‘justification’ in an externalist sense, specifically that certain procedures can track truth, and suggest that this recognition should inform practice; that one should try to determine which sources and methods are appropriate for various aspects of inquiry, and to what extent they are. Second, it argues that if there is external (...) justification, then a critical rationalist is better off than a dogmatist from an evolutionary perspective. (shrink)

Popper's methodology does not entail any playing down of the various indispensible distinctions such as the distinction between knowing and guessing, the distinction between myth and science, the distinction between the observational and the theoretical, and between the vernacular and technical sublanguages or technical vocabulary. By avoiding both the totalization that led to the foundationalist position and the scepticist reactions to these frustrated foundationalist hopes, Popper's methodology makes it possible to combine fallibilism with a realist view of theories. It combines (...) the perennial willingness to re-examine positions, statements, etc. with the claim that a particular theory (as an item of knowledge in the objective sense) constitutes cognitive progress over its rivals. However, some of his formulations have been deliberately provocative and in this way have given rise to certain misgivings about possible paradoxical implications, even in philosophers congenial with Popper's approach. The concept of knowledge in the objective sense is, of course, an explicatum which Popper proposes primarily for use in methodology and epistemology. The concept is an expression of the acknowledgment of fallibility in principle. The phrasing that ‘knowledge is conjectural’ or ‘knowledge is fallible’, even when it refers to knowledge in the objective sense, is but an abbreviation for: since our methods for ascertaining the truth-value of a particular statement about empirical reality are fallible in principle, there cannot be any certain knowledge about reality. In everyday life and in politics tolerance will be possible to the extent to which the recognition of this fallibility is more than a declaration. (shrink)

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

This is an important book precisely because there is none other quite like it.

In Science as Social Knowledge, Helen Longino offers a contextual analysis of evidential relevance. She claims that this "contextual empiricism" reconciles the objectivity of science with the claim that science is socially constructed. I argue that while her account does offer key insights into the role that values play in science, her claim that science is nonetheless objective is problematic.

In his book The Retreat to Commitment Professor Bartley raised an important problem: can rationalism can rationalism be held in a rational way, that is, in a way that complies with its own requirements? Or is there bound to be something irrational in the rationalist's position? Briefly, Hartley's answer was that an element of irrationalism is involved in extant versions of rationalism; however, Bartley proposed a new version of rationalism that can, he claimed, be held in a way that is (...) rational according to its own account of rationality. Bartley called this ‘Comprehensively Critical Rationalism’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:New Insights on Young PopperJohn R. WetterstenSeven essays that Popper wrote from 1925 to 1932–33 show Popper's transition from a fresh student of pedagogy into a serious philosopher of science ten years later. His first essay was published in 1925, and in 1934–35 he presented a revolutionary philosophy. These essays led first to Die beiden Grundprobleme der Erkenntnistheorie (written between 1930 and 1933 but first published in 1979) and (...) culminated in Logik der Forschung.1. Students as IndividualsIn his first published essay Popper argued that each student should be treated as an individual as much as possible.1 It is evident that Popper held this attitude throughout his life, but this essay plays no interesting role in his intellectual development.2. HeimatIn his second essay Popper developed an idea that was important not only for his pedagogy, but also for his psychology and his theory of the open society: because humans tend quite naturally to be dogmatic, they have to learn to overcome dogmatism in order to be rational.2 Following a perspective [End Page 603] heavily indebted to Eduard Burger,3 Karl Bühler,4 and Charlotte Bühler,5 Popper proposed that all aspects of learning begin with the beliefs and attitudes that one learns at "home." Teachers, Popper says, should not ignore the cultural background of their students. This background derives from their home, from their parents or village, and so forth. Teachers should accept the students' dogmatic acceptance of the views and attitudes of home as a necessary, even useful stage in any child's development. The teacher's central task is to help children move away from this dogmatic stage to broader perspectives. How to do this well, he says, poses a, if not the, central pedagogical problem. He discusses the movement from home to aesthetics, to art, to ethics, to law, to the theory of knowledge and science, and to culture. In each case he finds something in the heritage of home that each child possesses, which may be used as a starting point to expand the child's horizons.The problem of how teachers can sympathetically help children move away from the views of their home to broader perspectives is severe, Popper thought, due to the innate need of children to think dogmatically. When children learn the culture of their home they are given certainties that they cling to. As individuals mature, dogmatic thinking has to be overcome: a crucial task for teachers is to help children to set aside their innate dogmatic attitude to engage in critical thinking.At this time Popper was groping for a good philosophical approach. He said that the concept of "Heimat" had to be analyzed because, even though it was at the center of pedagogical concerns, it was a confused concept. This analytical method was quickly abandoned. It is only a historical curiosity that shows how far he had to go in order to develop a new philosophical method. Yet his use of it did bring him to adopt, or he used it to defend, views that he held throughout his life.3. Gewohnheit und Gesetzerlebnis in der ErziehungIn the same year (1927), in Gewohnheit und Gesetzerlebnis in der Erziehung, Popper turned to the task of providing a psychological explanation of the child's need for dogmatism. This third essay was submitted to the Pedagogic Institute, but only became available after Popper's death. Popper was ambivalent about it. When I visited him at his home in Penn in 1973 or 1974, I asked him for a copy. It was then listed in his bibliography, but there were no copies at the University of Vienna. His wife began to say she knew where it was, but he interrupted her before her sentence was completed. But he did not throw it away. The reason for his reluctance to show scholars his essay is [End Page 604] now clear: the essay endorses a philosophy of science—Hans Vaihinger's—with a strong inductivist component, even though its methodology is deductivist. He tried to apply this method in his own psychological investigation of dogmatism in children.Dogmatism was, he thought, a psychological... (shrink)

Ausgehend von einer Analyse des "Begründungsstreits", der in den letzten Jahren im Anschluß an H. Alberts Kritik des methodischen Prinzips der Begründung v.a. in der deutschen Philosophie geführt worden ist, werden zunächst die Positionen von K. O. Apel und J. Habermas einer immanenten methodischen Kritik unterzogen. Beide Programme erweisen sich als undurchführbar. Ausgehend von einer Präzisierung des Begriffes "Begründung" wird durch systematische Einführung begründungstheoretischer Termini ein begriffsiches Instrumentarium vorgeschlagen, das eine Rekonstruktion von Begründungssituationen erlauben soll. Mit seiner Hilfe werden die (...) im "Münchhausen-Trilemma" unterstellten Begründungssituationen genauer analysiert. Das "Münchhausen-Trilemma" wird als Argumentation für eine konstruktivistische und gegen eine reduktivistische Begründungskonzeption gewertet. (shrink)

Der kommunikativen Alltagspraxis müssen kognitive Deutungen, moralische Erwartungen, Expressionen und Wertungen einander durchdringen. Die Verständigungsprozesse der Lebenswelt bedürfen deshalb einer kulturellen Überlieferung auf ganzer Breite, nicht nur der Segnungen von Wissenschaft und Technik. So könnte die Philosophie ihren Bezug zur Totalität in einer der Lebenswelt zugewandten Interpretenrolle aktualisieren. Sie könnte mindestens dabei helfen, das stillgestellte Zusammenspiel des Kognitiv-Instrumentellen mit dem Moralisch-Praktischen und dem Ästhetisch-Expressiven wie ein Mobile, das sich hartnäckig verhakt hat, wieder in Bewegung zu setzen.

Karl Popper is one of this century's most influential philosophers, but his life in fin-de siècle and interwar Vienna, and his exile in New Zealand during World War II, have so far remained shrouded in mystery. This intellectual 2001 biography recovers the legacy of the young Popper; the progressive, cosmopolitan, Viennese socialist who combated fascism, revolutionized the philosophy of science, and envisioned the Open Society. Malachi Hacohen delves into his archives and draws a compelling portrait of the philosopher, the assimilated (...) Jewish intelligentsia, and the vanished culture of Red Vienna, which was decimated by Nazism. Hacohen's adventurous biography restores Popper's works to their original Central European contexts and, at the same time, shows that they have urgent messages for contemporary politics and philosophy.

Within Popper's philosophy of science there is a tension between two different and opposite tendencies of thought: one consists in a decisive critique of the neopositivistic philosophy of science, the other preserves instead some assumptions of gnoseology and ontology of Wittgenstein's Tractatus. The attempt to resolve the tension between these two tendencies of thought constitutes the spring that has guided the internal development of Popperian epistemology, from the falsificationism of Die beiden Grundprobleme der Erkenntnistheorie and Logik der Forschung to the (...) more recent theory of World 3. The thesis of a co-presence in Popper's thought of neo-positivistic and antíneopositivistic themes is here understood in a radical sense, which invests the gnoseological and ontological foundations of Popperian epistemology. The development of this thesis takes place by discussing the relevant literature of both the English and German linguistic area. Finally, the author has attempted to enucleate from Popperian epistemology those elements of thought that, if properly developed, would have allowed a re-reading in operational terms of the notion of scientific objectivity and would have made superfluous any Platonic theory of science, such as the Popperian theory of World 3, plagued by serious internal difficulties.

The book's essays represent an important contribution to the contemporary philosophical debate concerning Realism and Rationalism. The author defends in a clear and consistent fashion a fallibilist, realistic, and rationalist position in opposition to the idealistic and relativistic viewpoint characteristic of present postmodern philosophy.

Thomas Kuhn's _Structure of Scientific Revolutions_ has sold over a million copies in more than twenty languages and has remained one of the ten most cited academic works for the past half century. In contrast, Karl Popper's seminal book _The Logic of Scientific Discovery_ has lapsed into relative obscurity. Although the two men debated the nature of science only once, the legacy of this encounter has dominated intellectual and public discussions on the topic ever since. Almost universally recognized as the (...) modern watershed in the philosophy of science, Kuhn's relativistic vision of shifting paradigms -- which asserted that science was just another human activity, like art or philosophy, only more specialized -- triumphed over Popper's more positivistic belief in science's revolutionary potential to falsify society's dogmas. But has this victory been beneficial for science? Steve Fuller argues that not only has Kuhn's dominance had an adverse impact on the field but both thinkers have been radically misinterpreted in the process. This debate raises a vital question: Can science remain an independent, progressive force in society, or is it destined to continue as the technical wing of the military-industrial complex? Drawing on original research -- including the Kuhn archives at MIT -- Fuller offers a clear account of "Kuhn vs. Popper" and what it will mean for the future of scientific inquiry. (shrink)

David Miller elegantly and provocatively reformulates critical rationalism—the revolutionary approach to epistemology advocated by Karl Popper—by answering its most important critics. He argues for an approach to rationality freed from the debilitating authoritarian dependence on reasons and justification. "Miller presents a particularly useful and stimulating account of critical rationalism. His work is both interesting and controversial... of interest to anyone with concerns in epistemology or the philosophy of science." —Canadian Philosophical Reviews.

The essays in this volume represent an approach to human knowledge that has had a profound influence on many recent thinkers. Popper breaks with a traditional commonsense theory of knowledge that can be traced back to Aristotle. A realist and fallibilist, he argues closely and in simple language that scientific knowledge, once stated in human language, is no longer part of ourselves but a separate entity that grows through critical selection.

The first edition of this book profoundly challenged and divided students of philosophy, sociology, and the history of science when it was published in 1976. In this second edition, Bloor responds in a substantial new Afterword to the heated debates engendered by his book.
