Since the appearance of T. S. Kuhn's The Structure of Scientific Revolutions, scholars from various fields have sought to evaluate their disciplines in the light of Kuhnian criteria for scientific change. In this paper I argue that a new paradigm seems needed in high energy physics, and that there is no more reason to say that matter is made of elementary particles, than to say that it is not. My argument, that high energy physics is approaching a state of crisis, (...) and that a new paradigm is needed, is based on an examination of two events which, according to Kuhn, presage a conceptual revolution: (1) the "old" paradigm of normal science becomes unclear; and (2) this paradigm fails to support normal problem solving research, and scientists begin to use it as if it were merely definitional. After examining the elementary particles paradigm in the light of these two criteria, I conclude that high energy physics is moving from "normal science" to "extraordinary science." I argue neither that a new paradigm has been found, nor that a return to normal science is imminent; instead I attempt to briefly outline some of the conceptual problems in high energy physics to which Heisenberg, Feynman, and others have alluded, but which so far have not been spelled out in any great philosophical detail. No attempt is made to argue about what the specific consequences of these difficulties might be, but merely to begin to clarify the problems facing scientists dealing with elementary particles.

Norwood Russell Hanson was one of the most important philosophers of science of the post-war period. Hanson brought Wittgensteinian ordinary language philosophy to bear on the concepts of science, and his treatments of observation, discovery, and the theory-ladenness of scientific facts remain central to the philosophy of science. Additionally, Hanson was one of philosophy's great personalities, and his sense of humor and charm come through fully in the pages of Perception and Discovery. Perception and Discovery, originally published in 1969, is (...) Hanson's posthumous textbook in philosophy of science. The book focuses on the indispensable role philosophy plays in scientific thinking. Perception and Discovery features Hanson's most complete and mature account of theory-laden observation, a discussion of conceptual and logical boundaries, and a detailed treatment of the epistemological features of scientific research and scientific reasoning. This book is of interest to scholars of philosophy of science, particularly those concerned with Hanson's thought and the development of the discipline in the middle of the 20th century. However, even fifty years after Hanson's early death, Perception and Discovery still has a great deal to offer all readers interested in science. (shrink)

Analyses of Theories and Methods of Physics and Psychology was first published in 1970. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.This is Volume IV of the Minnesota Studies in the Philosophy of Science, a series published in cooperation with the Minnesota Center for Philosophy of Science at the University of Minnesota and edited by Herbert Feigl and Grover Maxwell. Dr. Feigl was the (...) director of the Center.In a preface to the first volume in the series, Professors Feigl and Michael Scriven noted the extensive concern of the Center with "the meaning of theoretical concepts as defined by their locus in the 'nomological net' and the related rejection of the reductionist forms of operationism and positivism." In this volume, several contributors are again concerned with philosophical, logical, and methodological problems of psychology. As before, some papers deal with broad philosophical issues, others with more specific problems of method or interpretation. However, a deep concern for logical and methodological problems of special relevance to the physical sciences is reflected in a number of essays.The contents are arranged in two sections, the first part being based on the papers and discussion from a conference held at the Center on the problems of correspondence rules. Contributors are Herbert Feigl, Paul K. Feyerabend, N.R. Hanson, Carl G. Hempel, Mary Hesse, Grover Maxwell, and William Rozeboom. The second group of essays, by various members of the staff of the Center and some of its visitors, reflects current issues and controversies of great interest. The contributors are William Demopoulos, Keith Gunderson, Paul E. Meehl (three essays), and Michael Radner. (shrink)
