This general issue of Democratic Theory begins with an important contribution by George Vasilev (La Trobe University) that reflects on Chantal Mouffe’s notion of democratic agonism. Mouffe has, primarily as part of her critique of deliberative democracy, asserted that consensus necessarily creates exclusion. What is important is that democratic dialogue remains open-ended. For her this means that democrats should view themselves as adversaries rather than antagonists who bring discussions to a close. Vasilev critiques Mouffe’s assertion by arguing that she holds a one-sided understanding of consensus that creates a less credible form of adversarial politics. By crafting a “norm of consensus”, Vasilev thus demonstrates that consensus formation can ensure the very condition of democratic freedom itself. In doing this, Vasilev’s argument brings a fresh perspective to ongoing debates in deliberative and agonistic democracy.
