Abstract

The report of B. M. Hessen at the at the scientific session at the Institute of philosophy in 1934, dedicated to the 25th anniversary of the publication of Lenin’s «Materialism and empiriocriticism». He said that statistical regularity appears already in classical physics, when it comes to kinetic theory, thermodynamics. But traditionally thinking physicists did not consider the statistical method full, believed, that statistical a near certainty can be to withdraw from dynamic. In quantum theory, it turned out that the dynamic laws are not applicable, because in principle you cannot set the status parameters of a single bodies. Simply discard causality is too simple and one-sided solution for physics. This is so just as philosophers seek out idealism in the works of modern physicists. The category of causality in need of rethinking.
