Medieval Philosophy explores the integration of rigorous reasoning with philosophical inquiry. The course begins with Ibn Sina, showcasing his pivotal role in bridging ancient philosophy with the medieval Christian and Islamic intellectual worlds, particularly in metaphysics. Equally central is Aquinas "On Being and Essence" a seminal work that synthesizes Aristotelian philosophy with Christian theology, offering profound insights into the nature of existence and being. Ockham introduces his famous “razor”, advocating simplicity and directness in understanding the world. Anselm's "Proslogion" with its ontological argument for God's existence, further enriches the course by blending theological thought with logical reasoning. This course invites students to explore the evolution of medieval philosophy, from its religious underpinnings to a stronger emphasis on logical analysis, providing a deep understanding of the period's intellectual advancements and their lasting impact on contemporary philosophical and theological discourse.
