"This book has been written in the war years 1941-42 under the occupation of Holland by the Germans. The author, who during many years attentively observed and sometimes actively took part in the workers' movement, gives here a summary of what from these experiences and study may be derived as to methods and aims of the workers' fight for freedom. What a century of workers' struggles presents to us is neither a series of ever again failing attempts at liberalism, nor a steadfast forward march of the workers following a fixed plan of old well-tried tactics.
