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.

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.

Of all philosophers of the 20th century, few built more bridges between academic disciplines than Karl Popper. He contributed to a wide variety of fields in addition to the epistemology and the theory of scientific method for which he is best known. This book illustrates and evaluates the impact, both substantive and methodological, that Popper has had in the natural and mathematical sciences. The topics selected include quantum mechanics, evolutionary biology, cosmology, mathematical logic, statistics, and cognitive science. The approach is multidisciplinary, opening a dialogue across scientific disciplines and between scientists and philosophers.

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.

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.

This 2001 biography reassesses philosopher Karl Popper's life and works within the context of interwar Vienna.

Science and the Open Society is a clearly argued and easy to read defense of Karl Popper's philosophy by Dr. Mark Notturno, the man whom Popper chose to research and edit his archives. The author argues that Popper's ideas about science and open society are still largely misunderstood in the West, while they are now more important than ever in providing inspiration for people in Central and Eastern Europe and Middle Asia, who are struggling to open up their closed societies. This groundbreaking volume draws together themes from Popper's epistemology and social philosophy showing, for example, the connections between his distrust of communism and inductivism, his resistance to institutionalized science and logical positivism, and his opposition to intellectual authority and bureaucracy, Notturno discusses Popper's disagreements with Wittgenstein, Freud, Carnap, Gruenbaum and Kuhn, while developing the implications of his view for a wide range of contemporary issues, including politics, education, logic, critical thinking and the history of twentieth century philosophy. Science and the Open Society is written for the general reader in a style that will appeal to philosophers and non-philosophers alike.
