With researchers funnelled into lucrative research practices that value fast scholarship, we explore ethical practice as an ethico-onto-epistemological project. Through collective biography, diffractive choreography, and poetry, we map systems of entrapment that manifest power relations in the academy. We argue the posthumanist ethical practice is an intra-active project in higher education -- involving rich material, social, political and intellectual entanglements. Posthumanist ethical practice rejects dualisms of body/mind, nature/culture and human/non-human. It evokes creativity to generate new vocabularies for challenging anthropocentric 'exceptionalism'. Mapping relations in posthuman assemblages can involve agential cuts that evoke ethical practice as affective encounters. Agential cuts give permission for pedagogic storying where there is ontological connectedness. As academics, we are immersed in assemblages where posthumanist education research and practice is a rich, embodied, and connected process. Particular consideration is given in this article to affectivity and the value of pedagogic performance in education research.
