In this podcast, Professor Iver B. Neumann takes the perspective that diplomacy is an emergent institution shaped by its social and material environment. Humanity shapes diplomacy, and diplomacy shapes humanity. An evolutionary frame provides us with a kind of longue durée overview. Further, he introduces and applies the idea of evolutionary tipping-points to the study of diplomacy. Tipping-points are the historical moment when long-term selection processes crystallise in diplomatic institutionalisation. He identifies six such tipping-points, and speculate about the emergence of a seventh, which challenges the present hierarchy of diplomatic agents.
