This article analyses the contributions of the sociologies or theories of the South to the contemporary debates on the production of theory in the social sciences. Starting with the assumption that these projects adopt a critical view of how sociology has privileged certain objects over others in a colonial way, it proposes an analysis that makes use of certain aspects of the actor-network theory. This approach, it is suggested, will help the sociologies of the South to focus on the production of ontoforms as their specific object, ontoforms which expand and at times challenge the established hegemonic notions of the social and of agency in this area of knowledge.
