Starting from a sympathetic attitude toward socialism in power, this book provides us with an extremely insightful interpretation of Stalin’s philosophy of socialism. It is not only a successful academic effort to re-articulate Stalin’s philosophy, but also a creative effort to understand socialism in power in the context of both the former Soviet Union and contemporary China. ———- Zhang Shuangli, Professor of Marxist philosophy, Fudan University Boer's book, far from both "veneration" and "demonization" of Stalin, throws new light on the classic themes of Marxism and the Communist Movement: language, nation, state, and the stages of constructing post-capitalist society. It is an original book that also pays great attention to the People's Republic of China, arising from the reforms of Deng Xiaoping, and which is valuable to those who, beyond the twentieth century, want to understand the time and the world in which we live. ———-Domenico Losurdo, University of Urbino, Italy, author of .
