Crises, in ever quicker succession, are shaking capitalist society: Corona pandemic, deep setbacks for the world economy, social emergency, the initiated global environmental catastrophe, the growing threat of world war, or the increasing danger of fascism. The bourgeois social sciences, religion and culture try to give answers, but are themselves affected by the state of crisis. They are far from "ideology-free" but instead spread the bourgeois worldview! This book espouses the ideology of the exploited and oppressed of this world and their justified cultural, ecological and social needs. It develops an unsparing critique of bourgeois-decadent culture while at the same time defending all valuable and progressive products of human culture. The book develops liberating visions of how a socialist society will solve the issues raised in a forward-looking way. This is the fourth volume of the book series, The Crisis of Bourgeois Ideology, and the Doctrine of the Mode of Thinking.
