This essay examines the labour required to produce, maintain and circulate concepts. Intellectual work is often represented through finished propositions while the repetitive, technical and editorial operations supporting them remain invisible. Socioplastics foregrounds this labour: naming, checking, linking, formatting, revising, archiving and sustaining a distributed corpus. The essay argues that concepts acquire force through infrastructures of care and repetition. Their apparent autonomy depends on material systems and human attention. The labour of concepts is therefore not external to theory; it is the process through which theory becomes durable, public and consequential. Its governing operator is RegimeMutation: conceptual labour becomes historically consequential when recurrent maintenance, revision and attention transform the regime organising intellectual production.
