The Summa Theologica is one of the most influential and comprehensive works of medieval philosophy and theology. Written by St. Thomas Aquinas, a brilliant theologian and scholastic philosopher, it covers a wide range of topics, from the existence and nature of God to the moral and political implications of human actions. In this voluminous text, Aquinas develops his famous arguments for the existence of God, the immortality of the soul, and the natural law theory, among other doctrines. He also engages with the works of his predecessors and contemporaries, such as Aristotle, Augustine, and Avicenna. Today, the Summa Theologica remains a key reference for scholars and students of philosophy, theology, and intellectual history.
