THE PROBLEM OF A PRIORI IN FUNDAMENTAL ONTOLOGY: A PRIORI PERFECT AND THE EXISTENTIAL-TEMPORAL CONCEPT OF PHILOSOPHY

Based on the philosophy of Martin Heidegger article presents possibility actualizing Heidegger’s main question about meaning Being in context analysis so-called “a priori perfect.” During development fundamental ontology second half 1920s, ponders approach to history and identifies such a feature as priori, kind antecedence relation being. Although tradition invariably understands this way, it, according Heidegger, is no longer raised either sense antecedence, or temporal basis sense, therefore essential character left total oblivion. We suggest that it problematization apriority its origin can contribute resolving philosophical time transcendental horizon any concept precedes In precedence there cherished moment, comprehension which allows us develop “basic metaphysics” relationship more concrete way than four themes Being: ontological difference; basic articulation (essentia/existentia)); truth-character Being; possible modifications unity Being’s variety. Revealing central all Heideggers thinking before “Turn” we attempt update justify need for renewal ontology. With task relate essence general existential-temporal since appears temporality-based questioning return “earlier”: structures being, knowledge, Being, Dasein. Our based following decisions: (1) being always pre-understood “earlier,” understanding definition operates, hence be developed at least clarified through problem priori. (2) The “earlier” concretized into conditions ontology, including raises earlier “lives” light such. (3) This reflexive foundation from itself necessary stage developing project, if remember “duty” philosopher clarify “our inner nature” sake opening boundaries philosophy. conclusion possibilities making time, are far exhausted, but await questions actualize them new readings allow see hidden richness thought.
