The Late Heidegger’s Negative-Theological and Mystical Methodology and its Ontological Significance : Focus on the Possibility of Contribution to Overcoming the Ecological Crisis and Mutual Dialogue between Eastern and Western Thought

The purpose of this study is to understand the later Heideggerian thought within the characteristics of the negative-theological and mystical methodology and to reveal its ontological significance thereafter. First, in Chapter 2, we examine the problematic awareness and methodology of Heidegger’s philosophy. And this implies the forgetfulness of Being (Seinsvergessenheit) and the instrumentalization and objectification of the world that appears as a result, and we reveal that we are using the phenomenological-hermeneutic methodology to resolve it. In Chapter 3, we interpret the turn of Heidegger’s thought and his later methodology as a negative theological-mystical methodology. The turn is a phenomenon that appears through the experience of the limits of Heidegger’s thought, and this makes the negative theological-mystical methodology possible. In Chapter 4, we examine the meaning that the discussion of the later Heidegger is revealed through the negative theological-mystical methodology. This means that Being itself is interpreted as an event of giving, indicating an alternative to the ecological crisis and a deep connection with Eastern thought.
