Philosophy of Religion

According to the Stanford Encyclopedia of Philosophy, philosophy of religion is, "the philosophical examination of the central themes and concepts involved in religious traditions." It is an ancient discipline, being found in the earliest known manuscripts concerning philosophy, and relates to many other branches of philosophy, including metaphysics, epistemology, and ethics.

The philosophy of religion differs from religious philosophy in that it seeks to discuss questions regarding the nature of religion as a whole, rather than examining the problems brought forth by a particular belief system. It is designed such that it can be carried out dispassionately by those who identify as believers or non-believers.

Some aspects of Philosophy of religion has classically been regarded as a part of metaphysics. In Aristotle's Metaphysics, the necessarily prior cause of eternal motion was an unmoved mover, who, like the object of desire, or of thought, inspires motion without itself being moved. This, according to Aristotle, is God, the subject of study in theology. Today, however, philosophers have adopted the term "philosophy of religion" for the subject, and typically it is regarded as a separate field of specialization, although it is also still treated by some, particularly Catholic philosophers, as a part of metaphysics.

Although the term did not come into general use until the nineteenth century, perhaps the earliest strictly philosophical writings about religion can be found in the Hindu Upanishads. Around the same time, the works of Daoism and Confucianism also dealt, in part, with reasoning about religious concepts. The Buddhist writing in the Pali canon "contains acute philosophical thinking", and "we have in Buddhism a very shrewd grasp of the nature of religion as philosophy illuminates it."
