423 II. 4
Being and Time

That which is ontically so familiar in the way Dasein has been factically interpreted that we never pay any heed to it, hides enigma after enigma existential-ontologically. The 'natural' horizon for starting the existential analytic of Dasein is only seemingly self-evident.

But after the Interpretation of temporality which we have given thus far, do we find ourselves in any more promising a situation with regard to delimiting the structure of everydayness existentially? Or does this bewildering phenomenon make the inadequacy of our explication of temporality all too patent? Have we not hitherto been constantly immobilizing Dasein in certain situations, while we have, 'consistently' with this, been disregarding the fact that in living unto its days Dasein stretches itself along 'temporally' in the sequence of those days?1 The "it's all one and the same", the accustomed, the 'like yesterday, so today and tomorrow', and the 'for the most part'-these are not to be grasped without recourse to this 'temporal' stretching-along of Dasein.

And is it not also a Fact of existing Dasein that in spending its time it takes 'time' into its reckoning from day to day and regulates this 'reckoning' astronomically and calendrically? Only if both Dasein's everyday 'historizing'2 and the reckoning with 'time' with which it concerns itself in this historizing, are included in our Interpretation of Dasein's temporality, will our orientation be embracing enough to enable us to make a problem of the ontological meaning of everydayness as such. But because at bottom we mean by the term "everydayness" nothing else than temporality, [372] while temporality is made possible by Dasein's Being,3 an adequate conceptual delimitation of everydayness can succeed only in a framework in which the meaning of Being in general and its possible variations are discussed in principle.

1 'Haben wir bisher nicht ständig das Dasein auf gewisse Lagen und Situationen stillgelegt und "konsequent" missachtet, dass es sich, in seine Tage hineinlebend, in der Folge seiner Tage "zeitlich" erstreckt?' The older editions have 'stillgestellt' rather than 'stillgelegt.'

2 '"Geschehen"'. Cf. our note I, p. 41, H. 19 above.

3 Weil jedoch mit dem Titel Alltäglichkeit im Grunde nichts anderes gemeint ist als die Zeitlichkeit, diese aber das Sein des Daseins ermöglicht …'
