Philosophical theology is a branch of philosophy that explores questions about the nature of the divine, existence of God, and the relationship between faith and reason. It seeks to understand religious concepts through logical analysis and critical thinking, often addressing issues like the problem of evil, the nature of divine attributes, and the justification of belief in God. This field often intersects with other disciplines, such as metaphysics, ethics, and epistemology. Philosophers like Thomas Aquinas and Immanuel Kant have significantly contributed to philosophical theology, providing frameworks for discussing the compatibility of faith with rational thought and the implications of religious beliefs on moral behavior.
