Extract

Hardly any other problem has been discussed more than that of the status of time in modem physics. This is only natural since there are not many other more important problems in philosophy of science and in philosophy in general. There are also few other areas where controversies as well as confusion were more frequent. This is true not only of popular and semi-popular expositions of the Minkowski concept of space-time but also of a number of its philosophical interpretations. Generally we do not find anything of this kind in the writings of physicists, at least as long as they confine themselves to strictly mathematical and physical expositions; but when they sometimes venture beyond a strictly mathematical approach, they often do not escape certain unconscious or semi-conscious prejudices which are contrary not only to the spirit but sometimes even to the letter of relativity. The true significance of the relativistic fusion of space and time can be understood only when we contrast it with its classical counterpart, i.e., with what may be called the Newtonian space-time. Only on such a contrasting background will the revolutionary meaning of the new concept clearly stand out.

20 Quoted by Meyerson, op. cit., p. 104.

21 This argument was put forth by Hugo Bergman, Der Kampf um das Kausal gesetz in der jüngsten Physik, Braunschweig, 1929, pp. 25-28. This argument was adopted by A. Grünbaum, Philosophical Problems of Space and Time, New York, 1963 and Modern Science and Zeno's Paradoxes, Wesleyan Univ. Press, 1967, Ch. I. My answer to Grünbaum is in "The Myth of Frozen Passage" in Boston Studies in the Philosophy of Science, II, 1965, pp. 441-453 and "Relativity and the Status of Becoming," Foundations of Physics V, 1975, pp. 607-616. Some other defenders of the static interpretation of Minkowski's world ignore the basic difference between Newtonian and Einsteinian spacetime; for instance Donald Williams "The Myth of Frozen Passage" Journal of Philosophy, v. 40, 1951, p. 457 and W. Quine in his Word and Object, Cambridge, Mass., 1967, p. 160.

26 Mario Bunge, Foundations of Physics, New York, Springer Verlag, 1967, p. 206: "It is often claimed that SR [Special Relativity] has wiped out the difference between space and time and even between what has been and what may be: that it has spatialized time and that it pictures the world as a block given once and for all, so that nothing ever happens: everything would exist already in some region of the Minkowski space, which would be thoroughly homogeneous and isotropic. This is preposterous. SR cannot be even stated without the notion e.m. signal, and even e.m. signal is a process (sequence of events), not a static being."

The usual, uncritically accepted claim that Bergson "completely misunderstood relativity," has been recently challenged by Marie-Antoinette Tonnélat, Histoire du principe de relativité, Paris, 1971, p. 280-93; M. Capek, Bergson and Modern Physics, Dordrecht, 1971, esp. pp. 237-256; the same author "Ce qui est vivant et ce qui est mort dans la critique bergsonienne de la relativité," Revue de Syn thèse, 1980, pp. 313-344.
