" The persecution of opinion in Russia is more severe than in any capitalist country. I met in Petrograd an eminent Russian poet, Alexander Block, who has since died as the result of privations. The Bolsheviks allowed him to teach æsthetics, but he complained that they insisted on his teaching the subject “from a Marxian point of view.” He had been at a loss to discover how the theory of rhythmics was connected with Marxism, although, to avoid starvation, he had done his best to find out. Of course, it has been impossible in Russia ever since the Bolsheviks came into power to print anything critical of the dogmas upon which their regime is founded. "
