Аннотация:I explore the core Habermasian concept of rational consensus-formation and its counterfactuality before introducing the possibility of permanence of conflict, non-reciprocity and domination (i.e. of agonism) which may productively explain some of the powergames enacted in planning decision-making. In so doing I draw on the concept of agonism and introduce the political into Habermas' moral theorization. Where the personal and the political intersect there is a role for psychology. I illustrate how Habermas' communicative theorizing was itself partly developed from a psychoanalytical tradition before introducing some of the concepts popularized by Jacques Lacan. I conclude that development of communicative planning theory could usefully retain some of Habermas' psychological foundations while turning to the work of Lacan as a basis for an enhanced understanding of the realities of planning practice.
