A verdade como problema fundamental na ontologia fenomenológica de Martin Heidegger,

Abstract

This Graduate Dissertation aims to investigate one sentence, which is found on §44 of Being and Time, that is: “Dasein is 'in truth'”. We have, in this sentence, the question for the ontic-ontological character of the Being which we ourselves are, as related to its ontological constitution the oscillation between veiling and unveiling of its being. The question which permeates our research, thus, refers to the privileged way of being which we are, as well as to the rescue of the question for meaning when facing such privilege. What relation has this ontic-ontological privilege of Dasein with this rescue proposed by Heidegger’s phenomenology? How would truth be a fundamental problem in this way? All these questions guide our research which seeks clarification of this obscure sentence asserted by Heidegger in Being and Time, about a truth that inhabits Dasein and of a truth that it is "situated" because it exists. The question for truth is totally related to the fundamental ontology proposed by Heidegger because it is through it that the phenomenologist proposes the rescue of "aletheia" (truth as unveiling, thought by the Greeks) and reaffirms its "anteriority", necessary before the truth thought by traditional molds as a kind of homoiosis. It is through an attention to the pre-phenomenological intuitions of the Greeks that our philosopher reaffirms the scope of philosophy in the face of oblivion of tradition. Aletheia is original truth, it is true that dwells Dasein because it refers us to the event of transcendence that this Being essentially is. It is through this notion that we have the question of sense being reaffirmed, that is, by accompanying what shines so quietly in our being: the inaugural event. We have, by means of the phenomenological method of investigation, the possibility of this shine to reveal itself in a more penetrating way, putting us in the position of seeing originally, that is, since the event of the transcendental. For, as our phenomenologist tells us: the original truth is a transcendental truth. To achieve so, the general objective of this research is: 1) To expose the traditional way of conceiving that which is true in the context of a general science of being; 2) To elucidate how the heritage of tradition denies the character of aletheia (which still appears in Aristotle); 3) Clarify how we have the phenomenological method in Heidegger, being operated through a hermeneutic, that is, a phenomenological attention; 4) To enter the essential determinations of Dasein, through an unbiased look made possible by phenomenological hermeneutics.
