The essential concerns of conservatism are the same as those that motivated Nisbet's first and most influential book, The Quest for Community. In fact. Conservatism unites virtually all of Nisbet's work. In it, Nisbet deals with the political causes of the manifold forms of alienation that underwrite the human quest for community. The sovereign political state is more than a legal relationship of a superstructure of power, it is inseparable from its successive penetrations of man's economic, religious, kinship and local allegiances, and its revolutionary dislocations of established centers of power.
