In Marxism and the Open Mind, John Lewis seeks to explain Marxism as a system of thought. In doing so, he addresses the studied neglect or grotesque misrepresentation that he feels characterizes Western attitudes toward Marxism. Lewis also aims to stimulate what he believes to be a long overdue re-evaluation of Marxism in the light of what was contemporary thought in 1957, the year of the books original publication and the height of the Cold War era. The essays include chapters on human rights and a discussion on Marxism and liberty. Marxist ethics, a much-neglected theme, is the subject of an essay that deals with some of the most deeply felt criticisms of Marxism in the 1950s. The ethical aspects of Marxism are examined once again in a contribution to the debate on Marxism and religion.
