Brian Davies offers a full-scale introduction to Aquinas's philosophy, collecting in one volume the best recent essays on Aquinas by some of the world's foremost scholars of medieval philosophy. Taken together they illuminate the entire spectrum of Aquinas's thought: philosophy of nature, logic, metaphysics, natural theology, philosophy of mind, philosophy of action and ethics. Philosophically rigorous, readable, informative, critical, and evaluative of the texts of Aquinas, the essays are framed by a detailed introduction providing an account of Aquinas's life, works, and his major philosophical conclusion.
