In Division One of Being and Time Heidegger presents a novel categorization of what there is, and an original account of the project of ontology and consequently of the nature and genesis of those ontological categories. He officially recognizes two categories of Being: Zuhandensein and Vorhandensein. Vorhandene things are roughly the objective, person-independent, causally interacting subjects of natural scientific inquiry. Zuhandene things are those which a neo-Kantian would describe as having been imbued with human values and significances. In addition to (...) these categories, there is human Being, or Dasein, in whose structure the origins of the two thing-ish categories are to be found. This essay concerns itself with three of Heidegger’s conceptual innovations: his conceiving of ontology in terms of self-adjudicating anthropological categories, as summed up in the slogan that “fundamental ontology is the regional ontology of Dasein,” his corresponding anti-traditional assertion of the ontological priority of the domain of the Zuhandensein to that of the Vorhandensein, which latter is seen as rooted in or precipitated out of that more basic world of human significances, and the non-Cartesian account of awareness and classificatory consciousness as social and practical.
