By Karl R. Popper

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.

From the preface: Darwin’s theory of evolution by natural selection has always fascinated me, but over the years I have found a surprising variety of thinkers who cannot conceal their discomfort with his great idea, ranging from nagging skepti­cism to outright hostility. I have found not just lay people and religious thinkers, but secular philosophers, psychologists, physicists, and even biol­ogists who w'ould prefer, it seems, that Darwin were wrong. This book is about why Darwin’s idea is so powerful, and why it promises—not threat­ens—to put our most cherished visions of life on a new foundation.
