Thomas Aquinas (1224-74) was born in Naples of a powerful Italian family. He took part in the major philosophical and theological controversies of his day and fought the decisive battle which re-admitted the study of the works of Aristotle. In his work he attempted to harmonise the rational insights of the classical world with revealed Christian truths. [He reinterpreted the Augustinian view of history and politics by concluding that the state did have positive value in itself, as an expression of God's providence and will for mankind. Man fulfilled himself in two ways - as a good citizen and as a Christian seeking salvation. Aquinas is therefore seen as reconciling the views of the pagan Aristotle with the teachings of Christianity.] Aquinas' theory of the state helped to put European political thought on a new plane. This wide-ranging collection of papers investigates and illuminates various aspects of Aquinas' thought regarding Church and State, society, natural law, justice and political authority.
