In Marx’s thought, is ‘law of value’ a particular law of capitalism (historicism) or a general law of the economy (naturalism)? To clarify this ambiguity, this article proposes to employ the social ontology of Cornélius Castoriadis. For it, ‘labour’ is not a substance, but a recent historical creation through which, finally, the capitalist mode of production expresses a fundamental truth about all society’s way of being. From this perspective, we explore some consequences of this deconstruction for the theory of value as current neo-Marxist approaches may employ it today in their economic analyses.
