Heidegger calls his early philosophy a “science of being.” Being and Time combines phenomenological, ontological, hermeneutical, and existential themes in a way that is not obviously coherent. Commentators have worried in particular that Heidegger’s hermeneutical transformation of phenomenology is incompatible with his “scientific” aspirations. I outline three interpretations on which Heidegger cannot adopt Husserl’s “scientific” conception of phenomenology as eidetic, intuitive, propositionally articulated, and non‐relativistic due to his hermeneutical commitments. I argue that each of these readings rests on a misinterpretation (...) of one or more of three hermeneutical concepts that are central to Heidegger’s early thought: the understanding of being, the hermeneutical situation, and phenomenological destruction. By giving fresh analyses of these concepts, I show that Heidegger retains the scientific conception while refining it to avoid distortions that are introduced when inquiry is “infiltrated with traditional theories and opinions about being.” I also respond to the charge that Being and Time is a “disguised theology.”.
