Time is essentially a self-opening and an expanding into the world. Heidegger says that it is, therefore, difficult to go any further here by comparisons. The interpretation of Dasein as temporality in a universal ontological way is an undecidable question which remains “completely unclear” to him. Time as a philosophical problem is a kind of question which no one knows how to raise because of its inseparability from our nature. As Gadamer notes, we can say what time is in virtue of a self-evident preconception of what is, for what is present is always understood by that preconception. Insofar as it makes no claim to provide a valid universality, philosophical discussion is not a systematic determination of time, i.e., one which requires going back beyond time (in its connection with other categories).
In his doctrine of the productivity of the hermeneutical circle in temporal being, Heidegger develops the primacy of futurity for possible recollection and retention of what is already presented by history. History is present to us only in the light of futurity. In Gadamer’s interpretation, it is rather our prejudices that necessarily constitute our being. His view that prejudices are biases in our openness to the world does not signify the character of prejudices which in turn themselves are regarded as an a priori text in the terms already assumed. Based upon this, prejudices in this sense are not empty, but rather carry a significance which refers to being. Thus we can say that prejudices are our openness to the being-in-the-world. That is, being destined to different openness, we face the reference of our hermeneutical attributions. Therefore, the historicity of the temporal being is anything except what is past.
Clearly, the past is not some occurrence, not some incident in my Dasein, but its past; it is not some ‘what’ about Dasein, some event that happens to Dasein and alters it. This past is not a ‘what,’ but a ‘how,’ indeed it is the authentic ‘how’ (wie) of any temporal being. The past brings all ‘what,’ all taking care of and making plans, back into the ‘how’ which is the basic stand of a historical investigation.
Rather than encountering a past-oriented object, hermeneutical experience is a concern towards the text (or texts) which has been presented to us. Understanding is not possible merely because our part of interpretation is realized only when a “text” is read as a fulfillment of all the requirements of the tradition.
For Gadamer and Ricoeur the past as a text always changes its meaning in relation to the ever-developing world of texts; so it seems that the future is recognized as textual or the textual character of the future. In this sense the text itself is not tradition, but expectation. Upon this text the hermeneutical difference essentially can be extended. Consequently, philosophy is no history of hermeneutical events, but philosophical question evokes the historicity of our thinking and knowing. It is not by accident that Hegel, who tried to write the history of philosophy, raised history itself to the state of absolute mind.
What matters in the question concerning time is attaining an answer in terms in which the different ways of being temporal become comprehensible. What matters is allowing a possible connection between that which is in time and authentic temporality to become visible from the very beginning. However, the problem behind this theory still remains even after long exposure of the Heideggerian interpretation of whether Being-in-the-world can result from temporal being or vice versa. After the more hermeneutical investigation, it seems that Being-in-the-world must be comprehensive only through Being-in-time.
But, in The Concept of Time, Heidegger has already taken into consideration the broader grasp of the text by considering Being as the origin of the hermeneutics of time. If human Being is in time in a distinctive sense, so that we can read from it what time is, then this Dasein must be characterized by the fundamental determinations of its Being. Indeed, then being temporal, correctly understood, would be the fundamental assertion of Dasein with respect to its Being.
As a result, only the interpretation of being as its reference by way of temporality can make clear why and how this feature of being earlier, of apriority, pertains to being. The a priori character of being as the origin of temporalization calls for a specific kind of approach to being-a-priori whose basic components constitute a phenomenology which is hermeneutical.
Heidegger notes that with regard to Dasein, self-understanding reopens the possibility for a theory of time that is not self-enclosed. Dasein comes back to that which it is and takes over as the being that it is. In coming back to itself, it brings everything that it is back again into its own most peculiar chosen can-be. It makes it clear that, although ontologically the text is closest to each and any of its interpretations in its own event, ontically it is closest to itself. But it must be remembered that this phenomenology does not determine completely references of the text by characterizing the temporalization of the text. Through phenomenological research regarding the text, in hermeneutics we are informed only of how the text gets exhibited and unveiled.
