The preceding chapter examined Aristotle's articulation of the question of being in relation to Heidegger's attempts to bring to light the original significance of ancient ontology. It is on this basis that it is possible to turn to the analytic of Dasein presented in the text of Being and Time and specifically to the account of equipment that is an essential aspect of this analytic itself. The general concern of the chapter is to determine the manner in which this account of equipment relates to, or inheres in, Heidegger's destruction of the traditional content of ancient ontology as an attempt to think more originally the productive or technical horizon at the inception of philosophy.
