Thomas Aquinas (1225-1274) is an extremely influential figure in the history of Western thought and the Catholic church. In this major addition to the Cambridge Texts in the History of Political Thought series, Robert Dyson has translated texts by Aquinas that reflect the complete range of his thinking, and clearly show his development of a Christian version of the philosophy of Aristotle. His translations are supported by brief biographies, notes for further reading and a concise critical introduction.
