In recent years, demagogy, violence, cruelty, and vileness have seized a great country embarked on the path of socialist development. I refer, of course, to China. It is impossible without horror and pain to read about the mass contagion of anti-humanism being spread by "the great helmsman" and his accomplices, about the Red Guards who, according to the Chinese radio, "jumped with joy" during public executions of "ideological enemies" of Chairman Mao. The idiocy of the cult of personality has assumed in China monstrous, grotesquely tragicomic forms, carrying to the point of absurdity many of the traits of Stalinism and Hitlerism. But this absurdity has proved effective in making fools of tens of millions of people and in destroying and humiliating millions of intelligent citizens.
