The Philosophical Origins of Hermeneutical Phenomenology of Heidegger

Heidegger holds that, although Western philosophy begins with an inquisition of the meaning of Being as the purpose of Metaphysics, at the time, perverted by Plato, and the history of forgetting Being begins from that time. According to Heidegger, the crisis of European sciences and the death of meaning is caused by ontological nihilism. It initiates from the metaphysical dualism that has occurred during centuries of philosophizing due to the disregard of the concept of Being and the obfuscation of this most fundamental thing. Heidegger conceives that with hermeneutical and phenomenological analysis of Dasein as the primary habitat in which the first and most fundamental problem of philosophy, What is Metaphysics?, has become a new way of philosophizing, before the thinkers of the epoch to get rid of this "great desert that Every day expands" (Nietzsche's famous expression, which Heidegger analyzed in the book What is Metaphysics?). This inquiry attempts to examine the characteristics and goals of Heidegger's hermeneutical phenomenology in the criticism of previous philosophies and in line with fundamental ontology, which is a drawing for understanding Being.
