The death of Imre Lakatos on February 2, 1974 was a personal and philosophical loss to the worldwide circle of his friends, colleagues and students. This volume reflects the range of his interests in mathematics, logic, politics and especially in the history and methodology of the sciences. Indeed, Lakatos was a man in search of rationality in all of its forms. He thought he had found it in the historical development of scientific knowledge, yet he also saw rationality endangered everywhere. To honor Lakatos is to honor his sharp and aggressive criticism as well as his humane warmth and his quick wit. He was a person to love and to struggle with. PAUL K. FEYERABEND ROBERT S.

This third volume of Paul Feyerabend's philosophical papers, which gathers together work originally published between 1960 and 1980, offers a range of his characteristically exciting treatments of classic questions in the philosophy of science. It includes his previously untranslated paper 'The Problem of Theoretical Entities', and the important lecture 'Knowledge without Foundations', in which he develops the perspective on early philosophy and science put forward by Karl Popper. Other themes discussed include theoretical pluralism, the nature of scientific method, the relationship between theory and observation, the distinction between science and myth, and the opposition between 'rationalism' and relativism. Several papers from the 1970s detail his increasing preoccupation with the social status of science and with the decline (as he perceived it) in quality within the philosophy of science itself. The volume is completed by a substantial introduction and a comprehensive list of Feyerabend's works.
