The purpose of this article is to expand on Dialogical Self Theory and to illustrate its benefits for the analysis of narratives of leaving Islam in a post-migration context. With leaving one’s religion, complex mechanisms of doubt, uncertainty, and ethical self-making come to the fore. Being in a post-migration context raises additional issues of intersectionality. Dialogical Self Theory is well-suited for the close-reading and in-depth analysis of such trajectories out of Islam, because it firstly considers the actual voices and their interaction in self-narrative. Secondly, Dialogical Self Theory allows for the recognition of the complex embeddedness of these voices in discursive power-structures. Thirdly, it considers self-making agentic properties. The particular usefulness of this theory will be exemplified by applying its analytical tools to one such trajectory.
