Political philosophy appears to have recovered from its alleged death in the
middle of the last century, but now faces the realist charge that in the work of
John Rawls and those influenced by him it fails to be political in the right
way; it is merely “applied moral philosophy.” I dismiss
the hyper-realist position of authors such as Raymond Geuss for taking an
implausibly narrow view of politics. There is more merit in Bernard
Williams’s claim that legitimacy, not justice, is the central problem
of political philosophy. Yet we cannot understand the significance of
legitimation without referring to the moral values that are realized when it
succeeds. Thus, Williams fails to show that political normativity can be
detached entirely from ethics. Moreover the legitimacy requirements of a liberal
state, according to Williams, are substantively close to the requirements of
justice according to Rawls. In light of the latter’s turn to
“political liberalism,” they appear also to hold
convergent views about the status of the theories they are advancing. I conclude
by suggesting that the “applied moral philosophy” charge
would apply only to philosophers who believe that general moral principles, like
utility or rights, can do all the work of political evaluation. Politics does
indeed have special features that impose distinctive justificatory requirements
on its procedures and the outcomes they produce.
