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.

The several chapters of this classic volume focus on many key elements of Popper's thought and philosophy, now helpfully reappraised.

'Never before has there been so many and such dreadful weapons in so many irresponsible hands.' - Karl Popper, from the Preface All Life is Problem Solving is a stimulating and provocative selection of Popper's writings on his main preoccupations during the last twenty-five years of his life. This collection illuminates Popper's process of working out key formulations in his theory of science, and indicates his view of the state of the world at the end of the Cold War and after the collapse of communism.

Here is an idea that just might save the world. It is that science, properly understood, provides us with the methodological key to the salvation of humanity. A version of this idea can be found in the works of Karl Popper. Famously, Popper argued that science cannot verify theories but can only refute them, and this is how science makes progress. Scientists are forced to think up something better, and it is this, according to Popper, that drives science forward.But Nicholas Maxwell finds a flaw in this line of argument. Physicists only ever accept theories that are unified – theories that depict the same laws applying to the range of phenomena to which the theory applies – even though many other empirically more successful disunified theories are always available. This means that science makes a questionable assumption about the universe, namely that all disunified theories are false. Without some such presupposition as this, the whole empirical method of science breaks down.By proposing a new conception of scientific methodology, which can be applied to all worthwhile human endeavours with problematic aims, Maxwell argues for a revolution in academic inquiry to help humanity make progress towards a better, more civilized and enlightened world.

The Political Thought of Karl Popper offers a controversial treatment of Popper's ideas about politics, informed by Shearmur's personal knowledge of Popper together with research on unpublished material in the Popper archive at the Hoover Institute. While sympathetic to Popper's overall approach, Shearmur offers criticism of some of his ideas and suggests that political conclusions should be drawn from Popper's ideas which differ from Popper's own views. Shearmur introduces Popper's political ideas by way of a discussion of their development, which draws upon archive material. He then offers a critical survey of some of the themes from his Open Society and Poverty of Historicism, and discusses the political significance of some of his later philosophical ideas. Wider themes within Popper's philosophy are drawn on to offer striking critical re-interpretations of his ethical ideas and social theory. The book concludes with a discussion which suggests that Popper's views should have been closer to classical liberalism than they in fact were.

Karl Popper is one of the greatest and most influential philosophers of the twentieth century. Originally published in German in 2000, Herbert Keuth's book is a systematic exposition of Popper's philosophy covering the philosophy of science (Part 1); social philosophy (Part 2); and metaphysics (Part 3). More comprehensive than any current introduction to Popper, it is suitable for courses in the philosophy of science and the philosophy of social science.

This is a comprehensive introduction to the philosophical and political thought of Karl Popper, now available in English. It is divided into three parts; the first part provides a biography of Popper; the second part looks at his works and recurrent themes, and the third part assesses his critics. It was approved of by Popper himself as a sympathetic and comprehensive study, and will be ideal to meet the increasing demand for a summary introduction to his work.
