Concrete Being in the Praxis: On Heidegger's Interpretation of the Concept of ουσια in Aristotle

Heidegger opposes the translation of omicron upsilon sigma iota alpha as substance, while he advocates translating it directly as being. Following Aristotle, Heidegger tries to discover the being in the light of the daily productive experience, so that he connects omicron upsilon sigma iota alpha with the form (tau omicron tau iota (eta) over tilde nu epsilon(iota) over tilde nu alpha iota). At the same time, focusing on the phenomenon of motion, omicron upsilon sigma iota alpha is understood as the realization of the form, that is its constant presence. However, to develop an interpretative model that corresponding to the life practice, Heidegger must go beyond Aristotle. Exposing the various dimensions of the concept of delta upsilon nu alpha mu iota zeta and emphasizing the element of absence, Heidegger proposes the concept of the original absence so that he can understand the process of movement again from his own sight. Accordingly, a new interpretative model is developed, through which the omicron upsilon sigma iota alpha is understood as the concrete, future-oriented being.
