The main aim of this paper is to analyse the applications of Nietzschean genealogical method to the study of religions. We focus firstly on Nietzsche’s basic concepts: force, will to power, value, evaluation, and power and then go on to discuss some genealogical investigations of the religious phenomena. According to Nietzsche, the nihilist structure of European history is metaphysics itself, understood as Platonism, other-wise explained as a separation between “the real world” (of values and ideals) and the “apparent world” (of (...) sensitive things). With the help of genealogy, values and ideals are proven to be illusions or appearances; on the contrary, senses and instincts, feelings and affections are rehabilitated. In this way, Nietzsche discovers the finitude of man and reveals the original unity between body and value, between what is given to man and what he can do alone. (shrink)
