On Time and Being Heidegger's lecture on Time and Being together with a summary of six seminar sessions on that lecture a lecture on 'The End of Philosophy and the Task of Thinking' and a short retrospective piece on Heidegger's relation to phenomenology. This introduction will attempt to examine and clarify briefly the path from Being and Time to Time and Being. In Being and Time Heidegger moves from a phenomenological hermeneutic of human being toward a fundamental ontology of Being. In this work he uncovers layers of experience analyzing things of nature, artifacts and the core of human being in its basic structure of care. All three constitute the original indissoluble unity of being in the world.
