Martha Nussbaum and other ''liberal perfectionists'' have endorsed a r
obust doctrine of state responsibility that is perfectionist in its co
nception of well-being but liberal in its sensitivity to the autonomy
of individuals and the differences between them. This doctrine can be
understood as an effort to avoid the weaknesses of both an ''impartial
liberal'' model of state welfare responsibility insufficiently attent
ive to individual need, and a neoconservative model insufficiently sen
sitive to autonomy and pluralism. Yet this robust doctrine is vulnerab
le to the challenge that government concern for the quality of life ma
y encroach upon autonomy and threaten pluralism. This article argues t
hat liberal perfectionists can respond to this challenge by incorporat
ing greater emphasis on public dialogue and participation into their d
octrine.
