Unlike almost all other philosophers of science, Karl Popper sought to contribute to natural philosophy or cosmology – a synthesis of science and philosophy. I consider his contributions to the philosophy of science and quantum theory in this light. There is, however, a paradox. Popper’s most famous contribution – his principle of demarcation – in driving a wedge between science and metaphysics, serves to undermine the very thing he professes to love: natural philosophy. I argue that Popper’s philosophy of science (...) is, in this respect, defective. Science cannot proceed without making highly problematic metaphysical assumptions concerning the comprehensibility and knowability of the universe. Precisely because these assumptions are problematic, rigour requires that they be subjected to sustained critical scrutiny, as an integral part of science itself. Popper’s principle of demarcation must be rejected. Metaphysics and philosophy of science become a vital part of science. Natural philosophy is reborn. A solution to the problem of what it means to say a theory is unified is proposed, a problem Popper failed to solve. In The Logic of Scientific Discovery, Popper made important contributions to the interpretation of quantum theory, especially in connection with Heisenberg's uncertainty relations. Popper's advocacy of natural philosophy has important implications for education. (shrink)

‘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 Preface Written 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.

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.

This book offers a distinctive treatment of Hayek's ideas as a "research program". It presents a detailed account of aspects of Hayek's intellectual development and of problems that arise within his work, and then offers some broad suggestions as to ways in which the program initiated in his work might be developed further. The book discusses how Popper and Lakatos' ideas about "research programs" might be applied within political theory. There then follows a distinctive presentation of Hayek's intellectual development up (...) to The Road to Serfdom, together with critical engagement with his later ideas. The discussion draws on a full range of his writings, makes use of some neglected earlier work on social theory and law, and also draws on archival material. This book should appeal to anyone with an interest in Hayek's work, as well as to those with a concern for twentieth century intellectual history. (shrink)

The Bridgewater Treatises were among the most widely circulated books of science in early nineteenth-century Britain, yet little is known of their contemporary readership. Drawing on the new history of the book, this essay examines the .. "communication circuit" in which the series was produced and read, exploring some of the processes that shaped the meanings the books possessed for their original readers. In so doing, it seeks to go beyond the standard interpretation of the Bridgewater Treatises as contributing to (...) a "common context" for debate among the social and cultural elite. Instead, the essay demonstrates the wide circulation of the series among many classes of readers and shows that consideration of the distinctive meanings with which the books were invested by readers in divergent cultural groups serves to elucidate the contested meaning of science in the period. It is argued that by thus taking seriously the agency of all those involved in the communication circuit, including readers as well as authors and publishers, this approach supersedes the increasingly unworkable analytical category of "popular science.".

Essays over de in Oostenrijk geboren Engelse wijsgeer (geb. 1902).

'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. (shrink)

The later thought of Karl Popper—notably, his ideas about traditions and his “modified essentialism” in the philosophy of natural science— should lead to revisions in the political philosophy set out in The Open Society and Its Enemies. The structural approach allowed for by Popper's modified essentialism, and the delicate nature of traditions, buttress certain issues raised by Friedrich Hayek that pose serious problems for Popper's social‐democratic approach to politics. Fred Eidlin's review essay on my Political Thought of Karl Popper misses (...) these problems, and in general underestimates the difficulties that unintended consequences pose for any non‐utopian theory of politics. Thus, Eidlin uncritically cites Popper's abstract political recognition of unintended consequences and his idealized view of the political process, as if that puts to rest the questions my book asks.
