A striking feature of contemporary political philosophy is the emergen
ce of the nature of the political itself as a central theme of discuss
ion. There are various reasons for this development, but all of them m
erely reinforce the problem posed in its most stark form by postmodern
theory. This is the problem of determining what concept of the politi
cal, if any, can accommodate the extreme diversity that is the main fe
ature of contemporary western life. That is the question with which th
e present paper is concerned. The three currently influential concepts
of the political are analysed, after which it is suggested that a fou
rth concept, which is a revised and reformulated version of the classi
cal idea of civil association, provides the basis for a concept of the
political best suited to modern conditions of increasing diversity.
