This white paper takes the unknown and the vague and movement towards/in those realms – as frames for a discussion of present practice and emergent potentiality of anthropological engagement with peace (building) studies. Arguably, embracing the unknown or vague as generative constants as well as fundamental elements of non-linear peacebuilding further open collaborative, communicative spaces of possibility. Aspects of this discussion are drawn from broader conceptual/methodological considerations in both peacebuilding and social anthropology so as to contribute to an interdisciplinary alignment. Furthermore, the positions and persuasions in this work are (in)formed by extensive, on-going examinations of research and narratives active in Southeast Europe today. By looking to emergent concepts in peace studies via anthropology while moving with regional-specific ethnographies that speak back against North Atlantic hegemonies, there is offered a discussion that brings local realities into transnational (socio-academic) deliberations.
