ABSTRACT
This chapter shows how the idea that temporal forms are spontaneous imaginings on our part allows us to understand there to be a unity underlying the multiplicity of being. Other entities are understood either as like us (other Dasein) or not (things of use, mere things); and this understanding shows up in the ways that we grasp their temporal aspects. Through this we may account for, on the one hand, the regionalization of being (different ontological kinds) and the shared structure of being that each region has (that-being, what-being, so-being, or more traditionally, existence, essence, accidents, each of which marks an aspect of temporal manifestation). After working out the details of this, this chapter shows how this account allows for, on the one hand, an interpretation of certain kinds of ontological error – category mistakes and philosophical misinterpretation – as well as what it means to talk as Heidegger does about ontological truth as the basis for ontical truth. The chapter thus sketches how Heidegger’s project of fundamental ontology may be completed, despite his initial failure and ultimate refusal to do so.
