The author, Mary Marcy, was gifted with intelligence, integrity, honesty, courage, simplicity, selflessness, and other higher human qualities. This book was the result of those qualities. In it, she attempted to simplify the complex theories, concepts, and language of Marx and Marxism to make it easier and understandable to common working class and other men and women. She did an excellent job in doing that. This was a great service to them as well as to socialism. Capitalist and imperialist government repression and persecution ruined her career and life and the ungrateful American nation lost a great and passionate fighter and writer for justice and truth.
