Contributors to this collection were invited to consider key issues in diplomacy’s public turn during recent decades and to reflect on what successor generation scholars and practitioners should understand going forward in turbulent geopolitical and technological landscapes. This chapter summarizes areas of consensus on changes from earlier thinking and areas of difference on analytical, normative, and operational issues. The authors share common ground on three developments. First, the societization of diplomacy and diplomacy’s public dimension are established core concepts in academic study and diplomatic practice. Second, digitalized diplomacy and AI will enhance, disrupt, and transform diplomatic institutions and patterns of practice. Third, scholars and practitioners must engage in new ways with knowledge domains across the sciences, social sciences, and humanities. The collection also offers an array of perspectives sure to energize debate and prompt new ideas. Familiar areas of difference on terms, concepts, and definitions are reframed in the context of diplomacy’s societization and changing circumstances. Chapters reflect diverse perspectives on boundaries needed to define analytical concepts, disciplines, and practices of state-centric, sub-national, supra-national, and humanity-centric diplomatic actors. Other differences are revealed in multiple pathways to innovations in diplomacy’s institutions, tools, and methods. The authors’ ideas and insights will be foundational in future research and in advancing diplomatic practice.
