This paper addresses the question of why democracy is desirable in terms of a relational theory of democracy. The theory draws on concepts from Aristotelian, critical realist, and psychoanalytic theory. From Aristotle it takes the concepts of human flourishing and human virtues; from critical realism it takes the concepts of relational subjects and relational goods; from psychoanalysis it takes the concept of mutuality. The relational theory argues that democracy, particularly deliberative democracy, is desirable because it requires and facilitates the development (...) of citizens with the relational capacity of mutuality. The theory is developed sequentially in the following four theses. (1) The function of government is to promote the flourishing of its citizens. (2) Human flourishing results from citizens having access to relational goods. (3) Access to relational goods requires that citizens possess the relational capacity of mutuality. (4) Deliberative democracy is desirable because it both requires and facilitates mutuality. (shrink)
