This chapter examines three ways that political argument can affect democratic decision making and, thus, significantly mitigate the force of the social choice challenge. By engaging in political argument, relevant agents can settle the dimensions that, in any instance, structure their disagreements. This causal effect not only dampens the prospects that collective decision making will generate cyclical outcomes, it thereby reduces the opportunities for strategic manipulation that such instability presents. Once the analytical argument has established the possibility that voting, augmented by argument, could produce normatively legitimate decisions, the chapter considers two ways in which democratic argument can enhance the quality of such decisions: diversity and reflexivity.
