Abstract
A discussion of the problem of contradiction in mechanical motion has been in progress for a long time in the pages of Filosofskie nauki. The attention given that problem is no accident. In our day, problems concerning contradictions involved in rest and motion, the continuous and the discontinuous, the finite and infinite, etc., have moved from the realm of abstract consideration to that of the concrete and current handling of the subject matter of modern physics, mathematics, and other fields. It is natural that the present stage of knowledge of objective reality should occasion a revived interest on the part of logicians and philosophers in these problems, including the question of how objective contradictions may be expressed in scientific theories
