This book, first published in 1920, is an analysis of socialist trends and a synthesis of proletarian aims. It attempts to establish the new political philosophy of left-wing socialists and coins a new term, 'ergatocracy' to mean 'workers' rule' and the abolishment of class in the organisation of society.
