Abstract
This is a diligent and competent account of Popper’s philosophy of natural science primarily, and secondarily of his philosophy of the social sciences. There are discussions of such topics as the anti-positivistic origin of Popper’s views, his interpretation of probability, his theory of corroboration, his critique of Carnap, his elaboration of indeterminism, and his interpretation of quantum theory. In a chapter dealing with subjectivism, Ackermann develops Popperian arguments against the views of Paul Feyerabend and Thomas Kuhn and gives an insightful elaboration of Popper’s evolutionary epistemology.
