As a scientific and academic discipline, religion philosophy is relatively new and often misunderstood. While theology presupposes faith and speaks about God, the philosophy of religion speaks about religion itself. It is neither religious nor anti-religious, and it does not seek to advocate for or attack religion. Rather, it sets out to ponder it. Its basic assumption is that religion constitutes a historical and cultural fact that can be subjected to rational, scientific, and philosophical analysis much like any other aspect of culture. The illuminating essays on religion philosophy comprised in this compilation explore subjects such as the relationship between science and faith and the trilemma of philosophical-religious worldviews. Moreover, they also seek to provide clarification on the status, scope, and methodology of religion philosophy, and ultimately contribute to the normalization of the discipline of religious studies in the context of university education.
