Philippe Van Parijs’s Real Freedom for All is widely acclaimed for providing not only a sophisticated defence of unconditional basic income, but also a rigorous examination of many central issues within contemporary political theory. This collection, including a response by Van Parijs, provides a comprehensive assessment of his ‘real libertarian’ vision of radical social change. The contributors include Richard Arneson, Brian Barry, Thomas Christiano, John Cunliffe, Guido Erreygers, Hillel Steiner, Peter Vallentyne, Robert van der Veen, and Stuart White.
