Book excerpt: The veritable tsunami of anxieties that are affecting individual lives, the increasingly dysfunctional nature of society and the potential catastrophes of global conflict and of climate change, have a common cause. The inability of capitalism or the state to respond to existential crises and internal contradictions is the cause of what William Briggs terms A Cauldron of Anxiety. Briggs defends a Marxist perspective that would challenge this and provides an optimistic vision for the future.
