Philosophy of Religion is the branch of philosophy concerned with the philosophical analysis of religious beliefs and phenomena. It differs from theology in not being committed to normative conclusions (e.g., that a particular human is divine or that a particular ethical code is correct). Traditionally, philosophy of religion has dealt with, among other things, the evidence for or against the existence of one or more gods, the relationship between faith and reason, the occurrence of miracles, the nature of religious language, the problem of reconciling a good god with the existence of evil in the world, the problems of religious pluralism (e.g., do different religions have incommensurable beliefs?), the philosophical analysis of non-theistic religions, and the connections between biology and religious beliefs and experiences. The most related branches in philosophy are ethics, metaphysics, and epistemology, and other related topics include Atheism and Humanism.
