"Besides producing various groundbreaking inventions (one of them eventually won the Nobel Prize) and the gradual but steady raising of standards of living, the Cultural Revolution also produced a communist consciousness, as people are learning to live not just to survive but for the good of others, whether it be neighbors, fellow countrymen, or the whole mankind; and the development of this consciousness is guided and based on a certain ideology. This book, written by a group of workers in a cotton factory in Northern China, is a testament to it: through the study of the classical Marxist text Ludwig Feuerbach and the End of Classical German Philosophy, the workers, with the help of a theory tutor and a Party cadre, dissected the basics of materialist dialectics in very simple and straightforward words, venturing into the realm of religion, law, art, education, and science."
