At nearly 800 pages, it provides a rigorous, step-by-step account of Heidegger's complete philosophical trajectory, from his early "radical phenomenology" to his later meditative "thinking" of Being.
Richardson was the first to systematically explore the "turn" in Heidegger’s thinking. He demonstrates that while Heidegger’s focus shifted from the "being-there" (Dasein) of his early work to the "truth of being" in his later years, this was not a contradiction but a radical continuation of the same inquiry.
