This text explores the origins of "Great Philosophy," which the author attributes to a fundamental turn toward the self, encapsulated in the Delphic maxim "Know thyself!" This turn is not a one-time historical event but a continuous task for every thinker, requiring personal commitment and risk. The core issue lies in the interpretation of self-knowledge: a human being is not defined by what is "given," as that merely represents their past. True self-knowledge necessitates the ability to distance oneself from the past self and relate to oneself as a future being—someone one is yet to become. Philosophy is thus understood as a dynamic process of identity formation, where the essence of human existence lies not in what has already occurred, but in openness to future possibilities and personal responsibility for one's own self-transformation. This ontological perspective redefines the relationship between the subject and temporality, emphasizing the process of becoming over static being.
