Karl Popper – författare

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.

'We are workers who are adding to the growth of objective knowledge as masons work on a cathedral'- Karl Popper, Objective KnowledgeThe extent and scope of human knowledge is arguably one of humankind's greatest achievements. Since Descartes, however, the theory of human knowledge has been mainly what philosophers call subjectivist: even scientific knowledge was regarded as a special kind of human belief, but human nonetheless. In Objective Knowledge, which contains some of his most important writings on epistemology, Karl Popper breaks decisively and controversially with this view of human knowledge.A realist and a fallibilist, he argues that human knowledge, stated in human language, is no longer part of ourselves but open to objective criticism. Above all, Popper argues that human knowledge grows through a process of conjecture, testing and criticism. Such objective knowledge has significance also for us as individuals, as critical interaction with problem-situations and the constant process of trial and error playing a role in all walks of life, from philosophy and science to music and art.A brilliant exposition of Popper's theory of knowledge, this Routledge Classics edition includes a new Introduction by Jeremy Shearmur, which provides some helpful context to Objective Knowledge and Popper's philosophy in general.

At the age of eight, Karl Popper was puzzling over the idea of infinity and by fifteen was beginning to take a keen interest in his father's well-stocked library of books. Unended Quest recounts these moments and many others in the life of one of the most influential thinkers of the twentieth century, providing an indispensable account of the ideas that influenced him most. As an introduction to Popper's philosophy, Unended Quest also shines. Popper lucidly explains the central ideas in his work, making this book ideal for anyone coming to Popper's life and work for the first time.

‘If in this book harsh words are spoken about some of the greatest among the intellectual leaders of mankind, my motive is not, I hope, to belittle them. It springs rather from my conviction that, if our civilization is to survive, we must break with the habit of deference to great men.’- Karl Popper, from the PrefaceWritten in political exile during the Second World War and first published in two volumes in 1945, Karl Popper’s The Open Society and Its Enemies is one of the most influential books of all time. Hailed by Bertrand Russell as a ‘vigorous and profound defence of democracy’, its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems and through underground editions become an inspiration to lovers of freedom living under communism in Eastern Europe.Popper’s highly accessible style, his erudite and lucid explanations of the thoughts of great philosophers and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of The Open Society and Its Enemies and why it demands to be read today and in years to come.

Det öppna samhället och dess fiender är en av 1900-­talets viktigaste böcker - på samma gång en kraftfull kritik av de totalitära ideologiernas intellektuella ursprung och ett kompromisslöst försvar för de demokratiska institutionerna och det öppna samhället.

Det öppna samhället har inte bara ett historiskt intresse - som en ovanligt djupgående exponering av 1900-talets dominerande totalitära läror -, den är fortfarande en högaktuell text i vår samtid. De intellektuella svagheter som Popper identifierade i de totalitära rörelsernas tankesystem har en förmåga att ständigt dyka upp på nytt, i nya tappningar och sammanhang.

Detta är en efterlängtad och reviderad nyutgåva av Det öppna samhället och dess fiender, i översättning av Andrew Casson och Bo Ekström, med ett nyskrivet förord av Håkan Holmberg.

The relation between body and mind is one of the oldest riddles that has puzzled mankind. That material and mental events may interact is accepted even by the law: our mental capacity to concentrate on the task can be seriously reduced by drugs. Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical events, upon the mind of the recipient of the letter. This is what the authors of this book call the 'interaction of mental and physical events'. We know very little about this interaction; and according to recent philosophical fashions this is explained by the alleged fact that we have brains but no thoughts. The authors of this book stress that they cannot solve the body mind problem; but they hope that they have been able to shed new light on it. Eccles especially with his theory that the brain is a detector and amplifier; a theory that has given rise to important new developments, including new and exciting experiments; and Popper with his highly controversial theory of 'World 3'. They show that certain fashionable solutions which have been offered fail to understand the seriousness of the problems of the emergence of life, or consciousness and of the creativity of our minds.In Part I, Popper discusses the philosophical issue between dualist or even pluralist interaction on the one side, and materialism and parallelism on the other. There is also a historical review of these issues.In Part II, Eccles examines the mind from the neurological standpoint: the structure of the brain and its functional performance under normal as well as abnormal circumstances. The result is a radical and intriguing hypothesis on the interaction between mental events and detailed neurological occurrences in the cerebral cortex.Part III, based on twelve recorded conversations, reflects the exciting exchange between the authors as they attempt to come to terms with their opinions.

The Open Universe is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science.

Realism and the Aim of Science is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science.Realism and the Aim of Science is the first volume of the Postcript. Popper here formulates and explains his non-justificationist theory of knowledge: science aims at true explanatory theories, yet it can never prove, or justify, any theory to be true, not even if is a true theory. Science must continue to question and criticise all its theories, even those that happen to be true. Realism and the Aim of Science presents Popper’s mature statement on scientific knowledge and offers important insights into his thinking on problems of method within science.

Quantum Theory and the Schism in Physics is one of the three volumes of Karl Popper’s Postscript to the Logic of scientific Discovery. The Postscript is the culmination of Popper’s work in the philosophy of physics and a new famous attack on subjectivist approaches to philosophy of science.Quantum Theory and the Schism in Physics is the third volume of the Postscript. It may be read independently, but it also forms part of Popper’s interconnected argument in the Postscript. It presents Popper’s classic statement on quantum physics and offers important insights into his thinking on problems of method within science and physics as a whole.

Based upon the Kenan Lectures that Karl Popper delivered at Emory University in 1969, Knowledge and the Body-Mind Problem raises problems connected with human freedom, creativity, rationality, and the relationship between human beings and their actions. These are what Popper calls big issues - too big for easy answers, but too important to be ignored. In these lectures, and in the discussions that follow them, Sir Karl develops a theory of body-mind interaction. This theory involves evolutionary emergence, human language, and that realm of autonomous products of the human mind which Popper calls World 3. According to Popper, consciousness emerged in the course of evolution as a kind of control system for the body, like a driver is a control system for a car. Objective knowledge - the kind of knowledge that is found in books and libraries - then emerged in the course of evolution as a higher level control system for the mind. Simply put, objective knowledge is the mind's control system for critical problem solving. In this way, full consciousness - the kind of consciousness that humans can have - is anchored in World 3 and is closely linked to human language, problems, theories, and criticism. And it is mainly through this use of objective knowledge as a control system for critical problem solving that we are able to exercise our freedom, creativity, and rationality - first by making contributions, like science books and works of art, to World 3; and then by using these contributions to bring about changes in Worlds 1 and 2. The Kenan Lectures were well-attended and provoked lively discussions. This book is published in the same informal language in which they were originally delivered and so can be easily understood by a general audience.

In The Lesson of this Century Popper's purpose is to warn us against the increasing violence and egoism of our society. What solutions can we offer to the problems of the environment, demography and corruption? How can we prevent the violence our society engenders? How can we preserve our democratic system while at the same time paving the way for global peace? Popper believes that the philosopher has a duty to intervene in politics and he utters a clear call to all of us to recognise our responsibilities. He reminds us that it is our actions which will create the world of tomorrow.The interviews in this volume were originally given to the Italian journalist Giancarlo Bosetti. The volume also includes the transcript of an interview about the moral dangers of television not previously available in English.

One of the century's greatest and most influential thinkers, Karl Popper reminds us that we must recognize our responsibilities in preserving the democratic system we enjoy: it is our actions which will create the world of tomorrow.In these interviews with journalist Giancarlo Bosetti, Karl Popper ranges widely over contemporary political and social issues. He reflects on many topics, from the decline of the Soviet Union and the danger of a Third World War, to our obligations to children and the potentially harmful influence of television. He warns us that the increasing violence and egotism of our society, if unchecked, will imperil our civilisation. The volume also contains two talks on the theory of democracy, arguing that democracy has never been the rule of the people (nor can or should it be), but only the best method we know for preventing tyranny.

'I want to begin by declaring that I regard scientific knowledge as the most important kind of knowledge we have', writes Sir Karl Popper in the opening essay of this book, which collects his meditations on the real improvements science has wrought in society, in politics and in the arts in the course of the twentieth century. His subjects range from the beginnings of scientific speculation in classical Greece to the destructive effects of twentieth century totalitarianism, from major figures of the Enlightenment such as Kant and Voltaire to the role of science and self-criticism in the arts. The essays offer striking new insights into the mind of one of the greatest twentieth century philosophers.

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.Published in cooperation with the Central European University.

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.

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. Popper brilliantly demonstrates how knowledge grows by guesses or conjectures and tentative solutions, which must then be subjected to critical tests. Although they may survive any number of tests, our conjectures remain conjectures, they can never be established as true. What makes Conjectures and Refutations such an enduring book is that Popper goes on to apply this bold theory of the growth of knowledge to a fascinating range of important problems, including the role of tradition, the origin of the scientific method, the demarcation between science and metaphysics, the body-mind problem, the way we use language, how we understand history, and the dangers of public opinion. Throughout the book, Popper stresses the importance of our ability to learn from our mistakes. Conjectures and Refutations is essential reading, and a book to be returned to again and again.

In this long-awaited volume, Jeremy Shearmur and Piers Norris Turner bring to light Popper's most important unpublished and uncollected writings from the time of The Open Society until his death in 1994.After The Open Society: Selected Social and Political Writings reveals the development of Popper's political and philosophical thought during and after the Second World War, from his early socialism through to the radical humanitarianism of The Open Society. The papers in this collection, many of which are available here for the first time, demonstrate the clarity and pertinence of Popper's thinking on such topics as religion, history, Plato and Aristotle, while revealing a lifetime of unwavering political commitment. After The Open Society illuminates the thought of one of the twentieth century's greatest philosophers and is essential reading for anyone interested in the recent course of philosophy, politics, history and society.

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie – The Two Fundamental Problems of the Theory of Knowledge – as ‘…a child of crises, above all of …the crisis of physics.’ Finally available in English, it is a major contribution to the philosophy of science, epistemology and twentieth century philosophy generally.The two fundamental problems of knowledge that lie at the centre of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science. Popper seeks to solve these two basic problems with his celebrated theory of falsifiability, arguing that the inferences made in science are not inductive but deductive; science does not start with observations and proceed to generalise them but with problems, which it attacks with bold conjectures.The Two Fundamental Problems of the Theory of Knowledge is essential reading for anyone interested in Karl Popper, in the history and philosophy of science, and in the methods and theories of science itself.

With a new foreword by Scott Austin 'I hope that these essays may illustrate the thesis that all history is or should be the history of problem situations, and that in following this principle we may further our understanding of the Presocratics and other thinkers of the past. The essays also try to show the greatness of the early Greek philosophers, who gave Europe its philosophy, its science, and its humanism.' - Karl Popper, from the preface The World of Parmenides is a brilliant exploration of the complexity of ancient Greek thought and science by one of the twentieth century’s leading philosophers. It reveals the great importance of Presocratic philosophy to Popper’s thought as a whole and shows the profound enlightenment he experienced reading not only Parmenides but the wider world of Greek science and philosophy including Xenophanes and Heraclitus.
