The Cambridge Companion to Aquinas

This edited volume provides a comprehensive scholarly examination of Thomas Aquinas's philosophical and theological system, with particular attention to his arguments for God's existence and divine nature. The collection brings together leading medievalists and philosophers of religion to analyze Aquinas's synthesis of Aristotelian philosophy and Christian theology, demonstrating its continued relevance to contemporary philosophical debates about God.

The volume explores Aquinas's Five Ways, his proofs for God's existence that proceed from observable features of the world to the necessity of a first cause, prime mover, and necessary being. Contributors examine how Aquinas develops these arguments through rigorous philosophical analysis while maintaining their fundamentally theological purpose. The work situates these proofs within Aquinas's broader metaphysical framework, showing how his conception of God as pure act and subsistent being itself grounds his entire philosophical system.

Several chapters address Aquinas's treatment of divine attributes, exploring his via negativa approach and doctrine of analogy for speaking about God. The contributors analyze how Aquinas navigates between anthropomorphism and agnosticism, developing a sophisticated account of religious language that preserves both divine transcendence and the possibility of meaningful theological discourse. The volume examines his arguments for divine simplicity, eternity, omniscience, and providence, showing how these attributes follow from his fundamental conception of God as ipsum esse subsistens.

The collection engages with contemporary critics and defenders of Aquinas's natural theology. Contributors assess challenges from both analytic philosophers who question the logical validity of his proofs and post-modern thinkers who reject the entire project of rational demonstration of God's existence. The volume shows how Aquinas's approach offers resources for addressing perennial questions about the relationship between faith and reason, while acknowledging difficulties in translating his medieval framework for modern audiences.

Stump's editorial introduction situates Aquinas within thirteenth-century debates while highlighting his enduring significance. The volume demonstrates how Aquinas's careful integration of philosophical argumentation and revealed theology established a paradigm for rational reflection on God that continues to shape both Catholic theology and philosophy of religion. This companion serves as an authoritative guide to understanding Aquinas's theistic arguments and their place in ongoing discussions about God's existence and nature.
