Theories of deliberative democracy have faced the charge of leading to the unjust exclusion of voices from public deliberation. The recent rhetorical turn in deliberative theory aims to respond to this charge. I distinguish between two variants of this response: the supplementing approach and the systemic approach. On the supplementing approach, rhetorical modes of political speech may legitimately supplement the deliberative process, for the sake of those excluded from the latter. On the systemic approach, rhetorical modes of political speech are (...) legitimate within public deliberation, just so long as they result in net benefits to the deliberative system. I argue that neither of these two approaches adequately meets the unjust exclusion charge. Whereas the supplementing approach does not go far enough to incorporate rhetorical speech into public deliberation, the systemic approach goes too far by legitimising forms of rhetoric that risk only exacerbating the problem of unjust exclusion. More constructively, I draw on Aristotle’s conception of rhetoric, as an art that is a counterpart to dialectic, to argue for a constitutive approach to rhetoric. I show how this approach provides a more expansive notion of deliberation that remains normatively orientated. (shrink)
