Meta Ontology

Modes-of-being (Seinsarten) figure centrally in Heidegger's masterwork 'Being and Time'. Testimony to this is Heidegger's characterisation of two of his most celebrated enquiries---the Existential analytic and the Zeug analysis---as investigations into the respective modes-of-being of the entities concerned. Yet despite the importance of this concept, commentators disagree widely about what a mode-of-being is. In this paper, I systematically outline and defend a novel and exegetically grounded interpretation of this concept. Strongly opposed to Kantian readings, such as those advocated by Taylor Carman and Cristina Lafont, I interpret a mode-of-being as a universal that defines a district (Bezirk)---that is, a natural class of entities that ought to be conceptualised in a special way. As such, every mode-of-being plays an important metaphysical and epistemic role: serving both to unify a natural class of a high degree of generality and as the interpretandum of an act yielding the basic-concepts (Grundbegriffe) pertaining to the entities therein. In explicating and arguing for this interpretation, I attribute a characteristically Aristotelian philosophical position to the early Heidegger, encompassing both metaphysical and epistemological realism and a conceptualist theory of universals
