Book excerpt: First published in English in 1924 this ambitious work, by the famous Marxist theoretician Karl Kautsky, aims to provide nothing less than an "exposition of the methods to introduce socialism" amongst the capitalist economies of Europe in the post-World War One era. Looking back on the experiences of the German socialist movement and looking forwards to the likelihood of a Labour government in Great Britain, he discusses the problems facing a labour revolution in Europe, with particular reference to the role of the middle classes, the transitional period between capitalism and socialism, and the economic impact of a socialist revolution.
