It is clear in retrospect that Henri Bergson considered such con ceptual revolutions in physics inevitable and, further, that he was able schematically to foresee certain of their most important the oretical consequences. This is a remarkable achievement, parti cularly considering Bergson’s reputation as an “anti-scientific” or “literary” intellect; yet, at the present time Bergson’s interpreta tion of the physical sciences remains one of the least understood, least discussed, and least appreciated aspects of his thought. The present collection is an attempt to remedy this unfortunate situa tion by making clear both the extent of Bergson’s insight into the basic concepts of physics and the relevance of his insights to living issues in the philosophy of science. In the introduction to this volume, I have taken a first step to ward suggesting the contemporaneity of Bergson’s philosophy of physics by analyzing, at length, his philosophical method and ex plaining how this method, in spite of appearances, could have been expected to lead to scientifically prophetic insights. The charge of anti-scientific intentions with' which Bergson has been saddled is seen to be not merely misleading, but radically false: Bergson’s philosophy of intuition is the affirmation, not the nega tion, of science. Hopefully this realization will serve to unify, in a general way, the readings which follow. Most of the readings presented below appeared originally in European scholarly journals and have been translated for the first time from French and German.1 They represent a stimulat- 1 De Broglie’s essay “The Concepts of Contemporary Physics and Bergson’s V BERGSON AND THE EVOLUTION OF PHYSICS ing and highly informative philosophical-scientific literature, but one which, apart from studies like the present, would not only be inaccessible to the average reader interested in contemporary scientific thought, but also would remain little, if at all, known among English-speaking philosophers. The physicists and phi losophers whose views are expressed in this book are by no means in complete agreement, either among themselves or with Bergson’s ideas. Nonetheless, their essays gain in depth and impact when viewed as an interrelated body of opinion. Besides suggesting Bergson’s contemporaneity, then, this collection makes available a coherent literature relating to his work. Though the essays presented here were written at different times and from diverse viewpoints, it has been possible to divide them roughly into four categories. The first, introduced by Louis de Broglie, the originator of the wave theory of matter, concerns the relevance of Bergson’s thought to quantum physics, partic ularly to the problems raised by quantum indeterminacy, the wave-particle duality, and the problem of “time-reversal invari ance” (i.e.y the problem of whether temporal series can be re versed). The second, which begins with a discussion between Bergson and Albert Einstein, concerns the basic conclusions of relativity physics, particularly those relating to the question of the status of the multiple time series and the “dislocations of simul taneity” required in the special theory of relativity. The third in volves the consideration of Bergson’s concept of time from the viewpoint of Zeno’s famous paradoxes. The fourth and last sec tion consists in Professor Milic Capek’s masterful survey of Berg son’s contributions to our understanding of modem physics as a whole. One final word: the scientists and philosophers in this collection are concerned with Bergson’s reflections for other than mere “academic” reasons. These writers seek, by analyzing Bergson’s criticisms and claims, to clarify their understanding of basic con cepts involved in the evolution of physics. It can be argued that Ideas on Time and Motion” appears (in translation) as a chapter of his Physics and Microphysics; the translation, however, is fragmentary, and omits some of de Broglie’s most significant conclusions. My own translation is complete. vi PREFACE Bergson’s insights might prove useful not only in giving a co herent and intellectually satisfying interpretation of the basic concepts of contemporary physics, but also, as one of the au thors translated here has stated elsewhere,2 in suggesting further theoretical advances in that science. I would like to thank Dr. David A. Sipfle and Mary-Alice Sipfle for their very helpful suggestions concerning difficulties encoun tered in translating several articles and for collaborating with me in the translation of both Professor O. Costa de Beauregard’s essay, “Certain Aspects of the Irreversibility of Time in Classical and Quantum Physics,” and the dispute between Henri Bergson and Andre Metz over the interpretation of the special theory of relativity. Dr. John C. Osborne of the Department of Germanic and Slavic Languages of The University of Tennessee is to be thanked for helping me to render a more accurate “complete paraphrase” of Gunther Pflug’s passages on inner time and the relativity of motion than would otherwise have been the case. I would also like to thank William K. Sipfle, formerly of the physics department of Ripon College, Richard J. Noer, assistant professor of physics, Carleton College, and Dr. John Mowat of the physics department of Auburn University for technical ad vice and information concerning Professor Costa de Beauregard’s “Certain Aspects of the Irreversibility of Time in Classical and Quantum Physics.” Finally, I would like to express my gratitude to Professor Mili£ Capek and Professor Robert Blanche for carefufly correcting my translations of their essays, and to Professor Capek for suggesting important corrections to the text of certain other translations. The Journal of the History of Phi losophy is to be thanked for releasing Dr. David A. Sipfle’s article, “Henri Bergson and the Epochal Theory of Time,” thus making it possible for it to appear here for the first time. 2 Milic Capek, The Philosophical Impact of Contemporary Physics (New York: D. Van Nostrand, 1961). Capek’s thesis, that modern science has relied too uncritically on visual and spatial concepts for its models and conceptual schemes, in many respects parallels Bergson’s attitude toward scientific thought. vii ( ' * ■
