Exploring the meanings and powers of love from ancient Greece to the present day, Richard Gilman-Opalsky argues that what is called ‘love’ by the best thinkers who have approached the subject is in fact the beating heart of communism - understood as a way of living, not as a form of government. Along the way, he reveals with clarity that the capitalist way of assigning value to things is incapable of appreciating what humans value most. Capitalism cannot value the experiences and relationships that make our lives worth living and can only destroy love by turning it into a commodity.
