Article is a trying to merge two theories: actor-network theory (ANT) and world-system analysis (WSA). Such a synthesis gives us an opportunity to combine an ethnographic approach, focused on actors analysis of ANT, with a networked, global perspective proposed by WSA. Both theories share the same type of holistic/ecological ontology of human societies. This similarity is fully visible if we compare a notion of the collective (Latour) and a notion of world-system (WSA). This is challenge to traditional, modernist views of social ontology. Author propose a concept of “ontological imagination”, as a solution. This is proposition a radicalized version of “sociological imagination (C. W. Mills), more suitable to technoscientific societies. In the paper the theoretical considerations are supplemented by a case study about “tyranny of the moment” as an example of acceleration in contemporary culture. Article propose model of social time in global context. Time is treated as a very important factor in global inequalities within structures if modern world-system.
