This book presents an elaborate analysis of the widely discussed problem of reconstruction of scientific theory change, based on material from theoretical physics. It gives a detailed , although not complete, analysis of the ideas of such authors as T. Kuhn, I. Lakatos, P. Feyerabend, E. Zahar and G. Holton, the empiristic account of the notion of “crucial experiment”, as well as of some leading Russian philosophers of science such as V. Stepin, E. Mamchur and V. Branskii. On the (...) positive side, the book offers an original model of reconstruction of scientific theory change. As the author himself insists on several occasions, his model does not pretend to completeness. Nugayev’ s model of scientific theory change is extensively tested on the example of the Lorentz-Einstein transition. The result is an empirical justification of his model, which shows not only that it works quite well in this particular reconstruction, but also that it explains some historical facts that have been left aside by some other authors.

A comprehensible model is proposed aimed at an analysis of the reasons for theory change in science. According to the model the origins of scientific revolutions lie not in a clash of fundamental theories with facts, but of “old” fundamental theories with each other, leading to contradictions that can only be eliminated in a more general theory. The model is illustrated with reference to physics in the early 20th century, the three “old” theories in this case being Maxwellian electrodynamics, statistical (...) mechanics and thermodynamics. Modern example, referring to general relativity and quantum field theory fusion, is highlighted. Key words: Popper, Kuhn, Lakatos, Feyerabend, Stepin, Bransky,Mamchur, mature theory, structure, Einstein, Lorentz, , Boltzmann, Planck, Hawking, De Witt. (shrink)

INTERNATIONAL STUDIES IN THE PHILOSOPHY OF SCIENCE Vol. 5, number 1, Autumn 1991, pp. 79-87. R.M. Nugayev. -/- The fundamental laws of physics can tell the truth. -/- Abstract. Nancy Cartwright’s arguments in favour of phenomenological laws and against fundamental ones are discussed. Her criticisms of the standard cjvering-law account are extended using Vyacheslav Stepin’s analysis of the structure of fundamental theories. It is argued that Cartwright’s thesis 9that the laws of physics lie) is too radical to accept. A (...) model of theory change is proposed which demonstrates how the fundamental laws of physics can, in fact, be confronted with experience. -/- . (shrink)

Nancy Cartwright’s arguments in favor of the phenomenological laws and against the fundamental ones are discussed. I support and strengthen her criticism of the standard covering-law account but I am skeptical in respect to her radical conclusion that the laws of physics lie. Arguments in favor of the opposite stance are based on V.S. Stepin’s analysis of mature theory structure. A mature theory-change model presented here demonstrates how the fundamental laws of physics can be confronted with experience. Its case (...) studies include the Lorentz-Einstein-Bohr transition and modern General Relativity and Quantum Field Theory unification. (shrink)

A methodological model of origin and settlement of theory-choice situations (previously tried on the theories of Einstein and Lorentz in electrodynamics) is applied to modern Theory of Gravity. The process of origin and growth of empirically-equivalent relativistic theories of gravitation is theoretically reproduced. It is argued that all of them are proposed within the two rival research programmes – (1) metric (A. Einstein et al.) and (2) nonmetric (H. Poincare et al.). Each programme aims at elimination of the cross-contradiction between (...) the special theory of relativity and Newton’s theory of gravitation. New arguments in favor of Einstein’s programme are given. Nevertheless, this does not imply the necessity to rule out all the nonmetric theories, since Einstein’s and Poincare’s programmes are alternative only as different tools of the cross-contradiction elimination. In the other respects these programmes are complementary: description, explanation and prediction of gravitational experimental data entails the usage of the languages of nonmetric theories as well as of metric ones. The part of the present investigation elucidating the necessity of nonmetric theories is an implementation of the ideas of A.Z. Petrov, the founder of Kazan University Relativity Department. Late Alexei Zinovievich had frequently punctuated that the notion of Riemann space-time continuum common for all metric theories obfuscates all the gravitational notions considerably and hampers the analogies with other physical theories at hand. Since the ambiguity is a hallmark of all the general relativism notions, approach to their definitions “should be determined not by analogies and contingent facts, but by general considerations linked the physical measurements theory… No matter how far the events lie out of the frames of classical physical explanations, all the experimental data should be described by classical notions” (Petrov, 1965,pp. 59,66). Key words: Kip S. Thorne, A.P. Lightman, Stepin, theory of gravity . (shrink)

What are the reasons for theory change in science? –To give a sober answer a comprehensible model is proposed based on the works of V.P. Bransky, P. Feyerabend , T.S. Kuhn, I. Lakatos, K.R.Popper, V.S. Scwvyrev, Ya. Smorodinsky, V.S. Stepin, and others. According to model the origins of scientific revolutions lie not in a clash of fundamental theories with facts, but of “old” basic research traditions with each other, leading to contradictions that can only be eliminated in a more (...) general theory. The model is illustrated with reference to physics in the early 20th century, the three “old” research programmes in this case being Maxwellian electrodynamics, statistical mechanics and thermodynamics. Modern example, referring to general relativity and quantum field theory, is considered. Key words: Bransky, Feyerabend, Popper, Kuhn, Lakatos, Stepin, Einstein, Lorentz, Planck. (shrink)

A brief account of epistemological models that try to unfold the intertheoretic context of theory change is proposed. It is stated that all of them has a host of drawbacks, the most salient one being the lack of adequate description of the research traditions interaction process. The epistemological model of mature theory change, eliminating the drawback, is contemplated and illustrated.

Nugayev’s book is one of the first Soviet monographs treating the theory change problem. The gist of epistemological model consists in consequent account of intertheoretical relations. His book is based on the works of Soviet authors, as well as on Western studies (K.R. Popper, T.S. Kuhn, I. Lakatos, P. Feyerabend et al.) Key words: epistemological model, Soviet philosophy, Western studies .

In his book “Reconstruction of Scientific Change” R.M. Nugayev proposes a new model of theory change by analyzing the reasons for theory change in science. Nugayev’s theoretical concept is based on a realist’s philosophical attitude. The most important notions of Nugayev’ s conception of theory change are “theories’ cross” and “crossbred objects”, which he takes from the terminology of other Russian philosophers of science (Bransky, Podgoretzky, Smorodinsky). His investigations often refer to several famous Western philosophers. Yet his study is not (...) free of some drawbacks. Nevertheless, Nugayev’s book is worth reading and discussing within the current debate about the structure of scientific revolution and theory changes. (shrink)

The monograph is aimed at an analysis of the reasons for theory change in science. The writer develops a model of theory change according to which the origins of scientific revolutions lie not in a clash of fundamental theories with facts, but of ‘old’ fundamental theories with each other.
