This paper emerges from the joint research project Feminist Theorizings of Intersectionality, Transversal Dialogues and New Synergies, funded by The Swedish Research Council, where Sofia Strid and Anna Lundberg have set out to not only compare notes, but to explore and take seriously the challenge posed by transversal dialogue as a method. What happens when research and researchers, over a substantial period of time, establish and entertain an enduring dialogue, focusing on chosen aspects and areas of feminist theory and feminist research? Strid and Lundberg are both active in the field of feminist research, however the differences between them regarding epistemological home, theoretical playground, methodological toolbox and empirical stage are quite distinct. These differences make the dialogue exciting and challenging. The project involves face-to-face and online meetings, discussions, text exchanges and long e-mail conversations as follow-ups. Conceptually, the focus is intersectionality and the way in which the concept has travelled and evolved in contemporary feminist theory and research. In order to analyse the on-going dialogue between Strid and Lundberg on (amongst other things) intersectionality, and in order to elaborate a way of understanding, describing and conceptualizing the on-going process, Strid and Lundberg has turned to Mikhail Bakhtin’s work on dialogism. With this paper and in order to discuss and problematise the field of feminist theory as an authoritative discourse, Strid and Lundberg bring in yet another of Bakhtin’s concepts: heteroglossia. In this discussion, the clashes and interventions between theory and practice will function as a temporary touchstone.
