This is, I believe, a very promising direction for political philosophy.
Contrary to the current brand of liberalism, a reflection on liberal
democracy on those lines would not present it as the rational, universal
solution to the problem of political order. Neither would it attempt to
deny its ultimately ungrounded status by making it appear as the
outcome of a rational choice or a dialogical process of undistorted
communication. Because of the central role it gives to practices, such a
perspective could help us understand how our shared language of
politics is entangled with power and needs to be apprehended in terms
of hegemonic relations. It might also leave room for 'undecidability'
and be better suited to account for conflict and antagonism.
