This has to be envisaged as an 'ethico-political' enterprise, one that
concerns the specific values that can be realized in'the realm of politics
through collective action, and which does not deny the constitutive
role of conflict and antagonism and the fact that division is irreducible.
This last point indicates why Value pluralism" in its multiple
dimensions has to be taken seriously by political philosophers. We
need to make room for the pluralism of cultures, collective forms of life
and regimes, as well as for the pluralism of subjects, individual choices
and conceptions of the good. This has very important consequences
for politics. For, in the realm of politics, once the plurality of values is
granted along with their conflicting nature, undecidability cannot be
the last word. Politics calls for decision and, despite the impossibility of
finding a final grounding, any type of political regime consists in
establishing a hierarchy among political values. A liberal democratic
regime, while fostering pluralism, cannot equate all values, since its
very existence as a political form of society requires a specific ordering
of values which precludes a total pluralism. A political regime is always
a case of 'undecidable decided' and this is why it cannot exist without a
'constitutive outside'.
