Book-review of Ernesto Screpanti’s Libertarian Communism: Marx, Engels and the Political Economy of Freedom. In this book, Ernesto Screpanti questions the nature and status of freedom within both Marx’s thought and possible forms of communist organisation. By way of an argument which contends that communism should be understood as a theory of freedom, he extracts a deliberately individualistic version of communism from Marx’s work, and proceeds to develop this into a series of recommendations for practical-organisational forms. These forms, and the notion of freedom that they arise from, are, however, closely related to Screpanti’s adoption of an economic approach that consists of the quantification of freedom. This prompts a number of political and theoretical problems.
