Abstract

The editor has assembled these essays to support the thesis that Bergson considered "conceptual revolutions in physics inevitable [and that he foresaw] certain of their most important theoretical consequences." He introduces the collection with an intellectual biography indicating that, far from being antiscientific, Bergson was a respectful and diligent student of science. Several themes illustrative of the thesis run through the selections. One: Bergson's dualisms should be thought of as complementary, for example, intellect and intuition should be regarded as two forms of empiricism rather than as antithetical approaches to knowledge. Another: Bergson anticipated concepts of quantum physics, such as, the dynamic concept of matter and the complementarity of velocity and position. A third theme: Bergson's ideas are suggestive for future scientific investigation, for example, the speed of light may be thought of as a coefficient of equivalence between space and time, a first law of time analogous to the first law of thermodynamics; then Bergson's concepts are perhaps a challenge to develop a second law. Most of the essays, originally published at various times between 1922 and 1959, appear in English for the first time. They are presented in four groups: "Quantum Physics" in which L. de Broglie, S. Watanabe, O. Costa de Beauregard, and R. Blanché are concerned with concepts of motion, entropy, and time; "Relativity" in which appears material by Bergson, Einstein, and Metz on Bergson's criticism of relativity, and essays by G. Pflug, J. F. Busch, W. Berteval, and O. Costa de Beauregard on aspects of Bergson's attack on relativity; "Bergson's and Zeno's Paradoxes" in which D. A. Sipfle uses an analysis of The Arrow by V. C. Chappell to interpret Bergson's theory of time. Milic Capek sums up the volume in an essay arguing that Bergson's concept of psychologic existence, on which his theory of matter is based, suggests a transformation of the basic concepts of the physical sciences. This is a stimulating group of essays, imaginatively edited.--L. G.
