This paper analyzes why philosophy of religion can surprisingly be considered a rather new field in Russian philosophy. While religion has played a major role in modern Russian culture, the philosophy of religion is still searching a precise definition of its object and domain. Initially, Russian philosophies of religion were inspired by Western influential works, whereas philosophy of religion is barely considered as distinct from theology. As such, philosophy of religion presents a double origin: in a wide sense, it coincides (...) with philosophy, while in a more specific sense its origins are to be found in the modern era. From this point of view, Spinoza is seen as a seminal author for this field of work. This conception is analyzed and used to draw some perspective for the development of philosophy of religion in Russia. (shrink)
