Georg Henrik von Wright, born in Helsinki in 1916, is the most renowned Scandinavian philosopher of our time, and an outstanding contributor to many fields of philosophy. He has made important contributions to logical theory and extended the application of logic to new areas, making path-breaking discoveries in probability theory, induction, causation and determinism, human action, and ethics. This work contains von Wright’s intellectual autobiography, 32 major criticisms of his ideas, and von Wright’s replies to each of these papers, followed by a complete bibliography of his works.
