This paper aims at the construction of a structural coupling between object-oriented philosophy and Whitehead’s philosophy of organism by making a case for the primacy of the ontological principle through the proposal of a social object hypothesis. The social object here differs from traditional renderings of sociology, which are centered on humans’ activity and personalities, by way of recuperating Tarde’s social theory of associations. This theory provides us with a non-anthropocentric reading of sociality. This hypothesis will be furthered by the (...) introduction of the systemic category of internal/external, or system/environment, as a self-enclosure feature of social objects. Equipped with these two notions, we will discuss Graham Harman’s paper “Whitehead and Schools X, Y, and Z,” while rerouting his assessments to our own social object hypothesis. The final idea is to propose an alliance through the conception of a macro-ontological approach to philosophy of organism. We intend to show that this is not only coherently feasible regarding Whitehead’s own categoreal scheme, but also meets the requirements of being a real object in object-oriented ontology’s directives.
