中世哲学
Medieval philosophy places heavy emphasis on the "theological". With the possible exceptions of Avicenna and Averroes, medieval thinkers did not consider themselves philosophers at all: for them, the philosophers were the ancient pagan writers such as Plato and Aristotle. However, their theology used the methods and logical techniques of the ancient philosophers to address difficult theological questions and points of doctrine. Thomas Aquinas, following Peter Damian, argued that philosophy is the handmaiden of theology ("ancilla theologiae"). Despite this view of philosophy as the servant of theology, this did not prevent the medievals from developing original and innovative philosophies against the backdrop of their theological projects. For instance, such thinkers as Augustine of Hippo and Thomas of Aquinas made monumental breakthroughs in the philosophy of temporality and metaphysics, respectively.
