Book excerpt: Symbiotic Realism is a theory of relations in a globally-anarchic world of instant connectivity and interdependence. It aims to provide a comprehensive framework for understanding the character of relations generated by four interlocking facets of the global system: the neurobiological substrates of human nature: global anarchy: instant connectivity: and interdependence. It provides a way of understanding how a myriad of actors, including states, transnational corporations, women, the biosphere, and civilizations, help to shape and are shaped by the global system. It also contains a clear normative commitment to moving beyond the present limits of the structure and political organization of the global system towards a more just and peaceful global order.
