Thomas Kuhn's The Structure of Scientific Revolutions was published in 1962 and has become one of the most important works of the twentieth century. During the last twenty years of his life, Kuhn was radically rethinking the central concepts of Structure. When he died in 1996, he left an unfinished sequel to Structure and an assortment of essays written since 1977 that lay the conceptual groundwork for some of the unfinished portions of that sequel. Divided into three parts, The Road Since Structure is the fullest record we have at present of the new direction Kuhn was taking during the last two decades of his life. The first part of the book consists of essays in which Kuhn refines the basic concepts set forth in Structure-paradigm shifts, incommensurability, and the nature of scientific progress. In part II, Kuhn replies to many of the criticisms of his earlier work. And the third part of the volume is the transcript of a remarkable autobiographical interview with Kuhn conducted in Athens in 1995, not quite a year before his death. Here, the usually reticent Kuhn discusses his own intellectual development-his upbringing and thoughts about his education, the influence of his training as a physicist, his war work, his relations with his colleagues, the responses to Structure-and his struggles to define his philosophical position both before and after that landmark work. The Road Since Structure will intrigue everyone who has been engaged by Structure and the debates it launched. In it they will find the story not only of Kuhn's development but also of the man himself.
