POPPER, KARL Section Headings: Life Backdrop to his Thought The Problem of Demarcation The Growth of Human Knowledge ... 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

Published in book form 1945) "What a monument of human smallness is this idea of the philosopher king. What a contrast between it and the simplicity of humaneness of Socrates, who warned the statesmen against the danger of being dazzled by his own power, excellence, and wisdom, and who tried to teach him what matters most - that we are all frail human beings. What a decline from this world of irony and reason and truthfulness down to Plato's kingdom of the sage whose magical powers raise him high above ordinary men; although not quite high enough to forgo the use of lies, or to neglect the sorry trade of every shaman - the selling of spells, of breeding spells, in exchange for power over his fellow-men."

When I read in the invitation that I was supposed, so the letter runs, «to give a lecture on the area of Karl Popper and Aquinas», I realized that the task was not an easy one, even for a person like me who considers himself as a Thomist and has worked for thirty years on the philosophy of Sir Karl Popper. Indeed, it is difficult to find two authors so different as Aquinas and Popper. They differ widely in their religious beliefs, in their interests, in their methods and in their conclusions. Empirical science, which plays a central role in Popper's entire philosophy, was almost nonexistent in Aquinas' times.

85. Objective Knowledge By Karl Popper The next-to-last chapter of Popper s 1966 work Objective Knowledge. Includes a concise presentation of his epistemological views. http://www.marxists.org/reference/subject/philosophy/works/at/popper.htm

Karl Popper (1966) Objective Knowledge A Realist View of Logic, Physics, and History (1966) Source Objective Knowledge (1972) publ. Clarendon Press. The second last chapter is reproduced here. Thus, we have not made our world. So far we have not even changed it much, compared with the changes achieved by animals and plants. Yet we have created a new kind of product or artefact which promises in time to work changes in our corner of the world as great as those worked by our predecessors, the oxygen-producing plants, or the island-building corals. These new products, which are decidedly of our own making, are our myths, our ideas, and especially our scientific theories: theories about the world we live in. I suggest that we may look upon these myths, these ideas and theories, as some of the most characteristic products of human activity. Like tools, they are organs evolving outside our skins. They are exosomatic artefacts. Thus we may count among these characteristic products especially what is called 'human knowledge'; where we take the word 'knowledge' in the objective or impersonal sense, in which it may be said to be contained in a book; or stored in a library; or taught in a university. When referring to human knowledge, I shall usually have this objective sense of the word 'knowledge' in mind. This allows us to think of knowledge produced by men as analogous to the honey produced by bees: the honey is made by bees, stored by bees, and consumed by bees; and the individual bee which consumes honey will not, in general, consume only the bit it has produced itself: honey is also consumed by the drones which have not produced any at all (not to mention that stored treasure of honey which the bees may lose to bears or beekeepers). It is also interesting to note that, in order to keep up its powers to produce more honey, each working bee has to consume honey, some of it usually produced by other bees.

86. Prague Lecture Speech delivered by Popper in the Czech Republic shortly before his death. http://www.lf3.cuni.cz/aff/p2_e.html

Karl Popper 1994 PRAGUE LECTURE Mr. Rector, Mr. Dean, Ladies and Gentlemen. To the 3rd Faculty of Medicine of the Charles University and its Dean, Professor Hoeschl, and all of you who have come here today, I wish to express my deeply felt thanks for the great honour which you are conferring on me. To be in Prague again, after 60 years - and those were difficult years for everybody): - this is a great experience. I visited Prague from Vienna in 1912 and 1913, before the First World War, and also several times during the war. And it was at the latest in 1934 that I decided that Prague was the most beautiful city in Central Europe. This has not changed. But everything else has. 60 years ago, there lived in the Hradcany Tomas Garrigue Masaryk, the great founder of the Republic of Czechoslovakia, and its Liberator President. I deeply admire Masaryk. He was one of the most important pioneers of what I have called, one or two years after Masaryk,s death, the Open Society. He was a pioneer of an open society, both in theory and in practice; indeed, the greatest of its pioneers between Abraham Lincoln and Winston Churchill. Of the successor states of the Austrian Empire, now defeated and improverished, Masaryk,s creation, the Czechoslovak Republic, was the only successful one. It was a financial, an industrial, a political, an educational and a cultural success; and it was well defended.

His (Popper's) attack on Plato, while unorthodox, is in my opinion thoroughly justified. His analysis of Hegel is deadly. Marx is dissected with equal acumen, and given his due share of responsibility for modern misfortunes. The book is a vigorous and profound defence of democracy, timely, very interesting, and very well written." "The general guiding principle for public policy put forward in The Open Society is: 'Minimize avoidable suffering'." Followed by: "Maximize the freedom of individuals to live as they wish"

Publica en Sappiens Estás aquí: Sappiens Perfil de miembro: Visitante Subscríbete a la Newsletter Sappiens! Materia: Filosofía de la ciencia Título: Conjeturas y refutaciones. El desarrollo del conocimiento científico Autor: Karl R. Popper Publicado en: Castellano Editorial: Paidós Fecha publicación: "En el presente volumen, Karl Popper examina varias cuestiones relativas al desarrollo del conocimiento, a la historia de la ciencia y a la filosofía de la ciencia, vistas a través de la moderna metodología, pero también se ocupa de problemas de política y sociología, siempre aplicando sus peculiares procedimientos semánticos, lógicos y gnoseológicos. Los ensayos y conferencias que componen el texto son variaciones de un mismo tema: la tesis de que podemos aprender de nuestros errores. Se trata de una teoría acerca del conocimiento y de su desarrollo, una teoría de la razón y una teoría de la experiencia que no se resigna al escepticismo y afirma que la ciencia puede progresar. El conocimiento científico avanza a través de anticipaciones injustificadas, de presunciones, de soluciones tentativas para nuestros problemas a las que llamamos conjeturas, que, a su vez, son controladas por la crítica, esto es, por intentos de refutaciones, entre las que se cuentan tests severamente críticos. La crítica de nuestras conjeturas es de importancia decisiva: al poner de manifiesto nuestros errores, nos hace comprender las dificultades del problema que estamos tratando de resolver. De este modo llegamos a adquirir un conocimiento más profundo del problema y a estar en condiciones de proponer soluciones más maduras: la misma refutación de una teoría es siempre un paso adelante que nos acerca a la verdad."
