Аннотация:The talk regards the debates between physicists and philosophers in the Soviet Union in terms of
their attitude to the physical picture of the world. The establishment of dialectical materialism as the state ideology played in those discussions a negative role. In some cases (for example, with reference to " annihilation of matter", conservation law in weak interaction, the "equivalence" of mass and energy, etc.) philosophers turned to be closer to the truth than physicists. However, the use of
ideological arguments (accusing opponents in idealism, Machism, etc.) did not contribute to the
clarification of the truth. Behind the curtain of ideological arguments physicists could not see the
positive meaningful essence of philosophers’ argumentation, whereas philosophers were not able to
present their arguments in physical language, understandable for physicists.
