The tacit presupposition underlying all of Heidegger’s work, both early (regarding
Dasein) and late (regarding
Ereignis), was his retrieval of the unsaid in Aristotelian
κίνησις. As the prologue to a work-in-progress, this essay discusses how Heidegger’s approach to phenomenology laid the groundwork for his rereading of
κίνησις. Heidegger argued that Aristotle (1) understood
κίνησις ontologically as a form of being and (2) worked within an implicit proto-phenomenological reduction of being (
οὐσία) to intelligibility (
παρουσία). Heidegger, in turn, interpreted
παρουσία in terms of
ἀλήθεια on three distinct but interrelated levels. This prologue prepares the way for a discussion of Heidegger’s readings of
Physica III 1-3 and
Metaphysica IX and their impact on the topics of
Dasein and
Ereignis.
