Related Entries (in Stanford Encyclopedia of Philosophy) Life Realgymnasium Popper obtained a primary school teaching diploma in 1925, took a Ph.D. in philosophy in 1928, and qualified to teach mathematics and physics in secondary school in 1929. The dominant philosophical group in Vienna from its inception in 1928 was the Wiener Kreis Logik der Forschung in 1934. The book - which he was later to claim rang the death knell for logical positivism - attracted more attention than Popper had anticipated, and he was invited to lecture in England in 1935. He spent the next few years working productively on science and philosophy, but storm clouds were gathering - the growth of Nazism in Germany and Austria compelled him, like many other intellectuals who shared his Jewish origins, to leave his native country. In 1937 Popper took up a position teaching philosophy at the University of Canterbury in New Zealand, where he was to remain for the duration of the Second World War. The annexation of Austria in 1938 became the catalyst which prompted him to refocus his writings on social and political philosophy. In 1946 he moved to England to teach at the London School of Economics, and became professor of logic and scientific method at the University of London in 1949. From this point on Popper's reputation and stature as a philosopher of science and social thinker grew enormously, and he continued to write prolifically - a number of his works, particularly

The Criticism of karl popper in AnthonyO'Hear's An Introduction to the Philosophy of Science. Letter http://www.friesian.com/popper.htm

Sir Karl Popper (1902-1994) The most important philosopher of science since Francis Bacon (1561-1626), Sir Karl Popper finally solved the puzzle of scientific method, which in practice had never seemed to conform to the principles or logic described by Bacon. Instead of scientific knowledge being discovered and verified by way of inductive generalizations, leaping from data into blank minds, in terms that go back to Aristotle , Popper realized that science advances instead by deductive falsification through a process of "conjectures and refutations." It is imagination and creativity, not induction, that generates real scientific theories, which is how Einstein could study the universe with no more than a piece of chalk. Experiment and observation test theories, not produce them. This was not, in retrospect, so hard to understand; and some philosophers, like Kant , had come close to recognizing it. It is still subject to some dispute, though mainly from those who misunderstand the rejection of induction or who demand positive epistemic reasons for crediting theories that are derived negatively, by falsification. That is a reasonable enough demand, but the answer can only come from deeper philosophical epistemology, not from science or philosophy of science. That deeper epistemology is, in fact, Friesian The most important question about Popper for the Proceedings of the Friesian School is why, in

THE BRITISH ACADEMY Karl Raimund Popper by John Watkins London School of Economics Published (December 1997) in Proceedings of the British Academy , Volume , pp. 645–684 [This Web version of the obituary does not include the notes.] Contents: Vienna New Zealand Early Days at LSE Lakatos ... Retirement Karl Popper was born in Vienna on 28 July 1902, and died in London on 17 September 1994. Vienna In 1925 he enrolled in the newly founded Pedagogic Institute. He was soon giving unofficial seminars to fellow students. He said that he learnt very little from the teachers there; but he now met two university professors, Karl Bühler and Heinrich Gomperz, who were important for his intellectual development. His investigations began to shift from the psychology to the logic of scientific inquiry. In 1928 he received his Ph.D., passing with the highest grade; his examiners were Bühler and Moritz Schlick. He now became a qualified schoolteacher. At this Institute he also met Josefine Henninger, or ‘Hennie’; they married in 1930. It was the beginning of a remarkable partnership, each devoted to the other, which lasted until Hennie’s death in 1985. He was reading Kant intensively, and also works by contemporaries such as Rudolf Carnap, Kurt Gödel, Hans Hahn, Karl Menger, Hans Reichenbach, Richard von Mises, Friedrich Waismann, and Ludwig Wittgenstein. Gomperz introduced him to Victor Kraft, who was the first member of the Circle whom Popper had met and the author of a book on scientific method which he found valuable. He attended Carnap’s seminar in about 1929, and an uncle introduced him to Herbert Feigl, who encouraged him to publish his ideas in a book. This launched him into the writing of

27. The Problem Of Induction, By Sir Karl Popper Essay by karl popper, arguing that there is no such thing as inductive inference. http://dieoff.org/page126.htm

Home Popper has argued (I think successfully) that a scientific idea can never be proven true, because because no matter how many observations seem to agree with it, it may still be wrong. On the other hand, a single contrary experiment can prove a theory forever false. The Problem of Induction (1953, 1974) For a brief formulation of the problem of induction we can turn to Born, who writes: '. . . no observation or experiment, however extended, can give more than a finite number of repetitions'; therefore, 'the statement of a law - B depends on A - always transcends experience. Yet this kind of statement is made everywhere and all the time, and sometimes from scanty material. ' 1 In other words, the logical problem of induction arises from (1) Hume's discovery (so well expressed by Born) that it is impossible to justify a law by observation or experiment, since it 'transcends experience'; (2) the fact that science proposes and uses laws 'everywhere and all the time'. (Like Hume, Born is struck by the 'scanty material', i.e. the few observed instances upon which the law may be based.) To this we have to add (3) the principle of empiricism which asserts that in science only observation and experiment may decide upon the acceptance or rejection of scientific statements, including laws and theories. These three principles, (1), (2), and (3), appear at first sight to clash; and this apparent clash constitutes the logical problem of induction.

Popper, Karl (1902- ) Popper, Karl (1902- ) Philosopher, born in Vienna. He studied at Vienna University, where he associated with the 'Vienna Circle' of philosophers, though he was strongly critical of their logical positivism. In 1935 he published his first book on scientific methodology, Die Logik der Forschung (1934, The Logic of Scientific Discovery). He left Vienna during Hitler's rise to power, lectured in New Zealand (1937-45), finally becoming professor of logic and scientific method at London (1949-69). Later books include The Open Society and its Enemies (1945), a polemic directed against all systems with totalitarian implications, particularly Marxism, and The Poverty of Historicism (1957).

Karl Popper Philosophe britannique d’origine viennoise Après la 2è guerre mondiale, il crée le département de Philosophie, logique et méthode scientifique à la London School of Economics. Naturalisé britannique, anobli par la reine, Popper résidait toujours dans la banlieue de Londres à sa mort en 1994. En 1987, il a reçu le prix Alexis-Tocqueville. Ses publications et ses conférences ont bouleversé les méthodes de la recherche scientifique. Il énonce la théorie de la « réfutation » : parce qu’une hypothèse peut être « falsifiée », c’est-à-dire réfutée par l’expérimentation, d’autres hypothèses plus complètes peuvent être élaborées et la théorie peut progresser. Nous vivons une époque où l’humanité, grâce aux sciences, a résolu la plupart des problèmes. Rien dans le présent ne permet de prévoir le futur. Ce qui est scientifique, c’est ce dont la fausseté peut être démontrée. Le relativisme moral et intellectuel est la plus grave menace planant sur notre société. Il se réclame plutôt de la tradition des lumières, celle de Voltaire, Kant et Hume. « Le mouvement des Lumières, précise-t-il, remonte en fait à Socrate, et sa devise est : Je sais que je ne sais pas . » Objectivement, nous vivons à une époque où l’humanité, grâce aux sciences, a résolu la plupart des problèmes qui, jusqu’en 1945, paraissaient à peu près insurmontables. « Je ne sais pas pourquoi il en a été ainsi, mais c’est un fait. » Notre société est la plus confortable et la plus pacifique à avoir jamais existé ; elle est aussi la plus juste. « Dans mon enfance, raconte Popper, Vienne était comparable, par son mélange de luxe et de misère, à l’Inde actuelle Aujourd’hui, la misère a pratiquement disparu de l’Europe occidentale ; les disparités sociales excessives n’existent plus ; la liberté de choix des individus est devenue immense ; l’éducation, le sens de la responsabilité ont progressé. Autant de faits incontestables! Et tout cela s’est produit en une période très courte Nous avons également appris qu’aucune réforme sociale ou aucun progrès économique ne pouvaient être obtenus par la violence ; même les Soviétiques commencent à s’en apercevoir! »

The Proceedings of the Friesian School, Fourth Series Taking up again the tradition of the Friesian School , this is a non-peer-reviewed electronic journal and archive of philosophy, inaugurated on line July 6, 1996, four years before the end of the 20th Century , just as the brilliant, courageous, prolific, and little appreciated German philosopher Leonard Nelson (1882-1927) started his Abhandlungen der Fries'schen Schule, Neue Folge , attempting a "Reformation of Philosophy," four years after the beginning of the 20th Century. The essays at this site, addressing many philosophical, historical, scientific, religious, economic, legal, and political issues, range from the fully annotated and technical to more informal and discursive discussions, often originally written for undergraduate classes. Many items therefore should be intelligible to those not familiar with all the arcana of academic philosophy, or with academic philosophy at all. This is done deliberately, since the trend, by which philosophy has obscured and esotericized itself and mostly dropped out of popular and literate culture, should be resisted. Work of a similar range, with the appropriate philosophical orientation and grounding, is acceptable and desired.

Notebooks Karl Popper, 19021994 (Sat Oct 24 23:36:56 1998) Austrian-English philosopher, dead, alas, just as I began these notebooks. Popper was primarily a philosopher of science; his system, that of ``conjectures and refutations,'' of falsification, was elegant, coherent, and basically right-headed. Similar to that of such earlier methodologists as William Whewell and Claude Bernard (as Popper was among the first to admit), it was one of only three which, in this century, actual scientists have bothered to pay attention to, and easily the best of them, both in its intellectual quality and its effects. (The other two were the system of Kuhn, who set out to turn Popper upside down; and Machian positivism and its descendants, including the Vienna Circle of logical positivists , who Popper hung out with, but on many important points disagreed with. Positivism was restrictive but, aside from encouraging the behaviorists, mostly harmless; the latter, through no fault of Kuhn's own, has led to no good at all. - Of course, many scientists have been forced to pay attention to dialectical materialism, but on purely prudential, not intellectual, grounds; that doesn't count.) Even now, querying scientists about what they're up to is very likely to provoke more or less Popperian responses. That said, there are enough problems with it that I, for one, can't really accept it, and there are very few proper Popperians left among professional philosophers of science. On the other hand, his critism of such pretenders to scientific status as Marxism, the ``sociology of knowledge'' and, especially

Home About Hoover Research Publications ... Involvement HOOVER INSTITUTION HOOVER DIGEST 2000 No. 1 Piers Norris Turner Remembering Karl Popper A reflection on the life of former Hoover fellow Karl Popper, one of the past century’s greatest thinkers. Karl Popper One person’s life can sometimes tell the story of an entire century. Such is the case with Sir Karl Popper (1902–1994), one of the foremost critics of authoritarianism in the twentieth century, yet also arguably the premier philosopher of science during a century of unparalleled scientific discovery. THE OPEN SOCIETY AND ITS ENEMIES In 1989, the fall of the Berlin Wall brought renewed interest in Popper’s major contribution to political philosophy, The Open Society and Its Enemies . When The Open Society Popper was a fallibilist , one who perceives great error and danger in any theory of knowledge—or regime—that claimed to offer certain truth. In such a system, there would be no incentive to establish social and political structures that promote learning or the free exchange of ideas; truth is already at hand. In the name of historical progress, the regime may then justify the squelching of human freedoms and even atrocities on a grand scale. Consequently, Popper fought against those who claimed to know the historical laws of change, a false doctrine Popper called historicism. Historicist prophecies were a threat to the open society, and, indeed, both nazism and Soviet-style totalitarianism alike produced unimaginable horrors. Despite its success in articulating the inherent threat of Marxism, Popper’s book is not about Soviet Russia or conceived of as a Cold War tome. In fact, Popper developed his ideas just before World War II, in a radically different geopolitical landscape. Yet, soon after it appeared
