The purpose of Part II of this book is to explore, at a more concrete level, the relationship between law and capitalist social relations, through a close genealogical study of the social category of the wage. This means tracing the evolution of this category through legal discourse, as capitalism developed in the United Kingdom. Chapter 4 will lay the groundwork for this analysis by specifying the methodological assumptions underpinning this genealogical analysis, while exploring, in more detail, how the contradictions inherent in capitalism manifest in the social category of the wage. The first section explains the nature, and importance, of ‘genealogy’. The second section explores two different conceptions of the wage in economic theory, with a view to teasing out the nature and significance of the wage as a social category and the contradictory functions it performs in capitalist society. The third section discusses the relevance of these ideas to our understanding of law’s role in relation to wage regulation, and employment status, by showing how approaches to these questions are influenced by legal actors’ beliefs about law’s ontology.
