Abstract
This paper demonstrates that the historical materialist framework deployed in Utopia Ltd. is implicitly critical realist at the level of social ontology. It supplies critical realist concepts that are only implicit in the analysis, for example ‘the pulse of freedom’, and suggests a provisional critical realist typology of utopian epochs on the basis of the one that Beaumont implicitly deploys, thereby demonstrating that critical realism can sharpen, deepen and add a more adequate philosophical rationale to substantive Marxist analysis even when, like Beaumont's, it is an outstanding example of its kind. By the same token, it shows that analyses such as Beaumont's can make important contributions to critical realism.
