iWe know that communism is the right hypothesis. All those who abandon this hypothesis immediately resign themselves to the market economy, to parliamentary democracy--the form of state suited to capitalism--and to the inevitable and 'natural' character of the most monstrous inequalities.i--Alain Badiou pAlain Badiou's communist hypothesis, first stated in 2008, cut through the cant and compromises of the past twenty years to reconceptualize the Left. The hypothesis is a fresh demand for universal emancipation and a galvanizing call to arms. Anyone concerned with the future of the planet needs to reckon with the ideas outlined within this book.
