Abstract: Some social choice theorists attempt to turn the science of politics against democracy in general and deliberative democracy in particular. They claim the arbitrariness and instability of democracy will be exacerbated by unconstrained deliberation. The response shows that there are mechanisms endogenous to deliberation that can respond to the social choice theory critique, emphasizing the construction of public opinion through the contestation of discourses in the public sphere and its transmission to the state by communicative means, including rhetoric.
