About Conjectures and Refutations: The Growth of Scientific Knowledge

Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, offering a clear and accessible statement of his central idea: knowledge grows through an unending process of trial and error. Popper argues that scientific theories are bold conjectures that we test and refute, not verify. He applies this insight not only to the natural sciences but also to politics and history, defending the open society and criticizing historicism. The book includes famous essays on the demarcation of science from pseudoscience, the nature of philosophical problems, and the role of criticism in intellectual life. This Routledge Classics edition makes Popper's influential epistemology available to a new generation of readers, demonstrating why his ideas remain vital for understanding science, democracy, and the pursuit of knowledge.
