ABSTRACT
The Russian revolution set free a great body of Marxian theorists, and theorists willing to become Marxian, if only from the pure love of theory. It supplied them with publishing facilities, and encouraged them to take possession of the whole field of science in the name of Dialectic Materialism. Naturally the science of psychology did not escape this invasion. It was approached with somewhat the same mixture of caution and contempt with which one approaches a poisonous reptile and a certain preliminary investigation was begun. Enough progress has been made to indicate what an orthodox "Marxian Psychology" will be, when it is fully developed. Among the extremer devotees of dialectic materialism in Russia, the very word psychology is denounced as bourgeois and counter-revolutionary. And these devotees imagine that what they are defending so fanatically is the materialism of Marx, and that they want to put physiology in the place of psychology.
