"Subsidiarity is a communitarian philosophy. In this doctrine the human person cannot be understood apart from his communal nature and his communal existence. Subsidiarity claims that a communal, social and political existence is imposed on the human person by human nature, by the natural law and, ultimately, by God.
For the libertarian, by contrast, the human person is individualistic. The libertarian considers the communal, social and political aspects of human existence to be the result of human free choice and considers these aspects of human existence to be created by man rather than by God."
