New in paperback. Hardcover was published in 2017. Axel Honneth argues that the idea of socialism has lost its luster because its theoretical assumptions stem from the industrial era and are no longer convincing in our contemporary post-industrial societies. Only if we manage to replace these assumptions with a concept of history and society that corresponds to our current experiences will we be able to restore confidence in a project whose fundamental idea remains as relevant today as it was a century ago the idea of an economy that realizes freedom in solidarity. The Idea of Socialism was awarded the Bruno Kreisky Prize for the Political Book of 2015.
