This is the first book-length exploration of Karl Popper's often-neglected contributions to the philosophy of social science. William A. Gorton situates Popper's ideas on social inquiry within the broader framework of his thought, including his philosophy of natural science, his ontological theories, and his political thought. Gorton places special attention on Popper's theory of situational analysis and how it aims to heighten our understanding of the social world by untangling the complex web of human interaction that produces unintended—and often unwanted—social phenomena. Situational analysis, Gorton contends, involves a significant departure from the method of the natural sciences, despite Popper's plea for the unity of scientific method. Gorton also addresses some common misconceptions concerning Popper's stance toward economics and Marxism, making the provocative claim that contemporary analytical Marxism provides the best current example of Popperian social science put into practice.

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.

This book offers a straightforward account of Sir Karl Popper's views on scientific methodology ranging from Logik der Forschung in 1934 to A World of Propensities in 1990. Part I covers his treatment of the interrelations between metaphysics and science, the fallacies of induction, the method of conjectures and refutations, evolutionary epistemology, the propensity theory of probability, and the interpretation of quantum mechanics. Part II considers the problems of the social sciences, his critiques of historicism and holistic planning, his defence of piecemeal planning on both scientific and humanist grounds, his method of situational logic based on models that use a 'rationality principle', and the roles of institutions, traditions and history. The book is addressed to those who are interested in general problems of scientific method but find it difficult to get a clear or connected view of Popper's important contributions because these have been published over long intervals and have been subject to misinterpretations.

This is one of the most comprehensive collections of critical essays to be published on the philosophy of Karl Popper.

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.

Rectifying misrepresentations of Popperian thought with a historical approach to Popper’s philosophy, Gattei reconstructs the logic of Popper’s development to show how one problem and its tentative solution led to a new problem.

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.
