" Dasein does not fill up a track or stretch ‘of life’ — one which is somehow present-at-hand — with the phases of its momentary actualities. It stretches itself along in such a way that its own being is constituted in advance as a stretching-along. The ‘between’ which relates to birth and death already lies in the being of Dasein … It is by no means the case that Dasein ‘is’ actual in a point of time, and that, apart from this, it is ‘surrounded’ by the non-actuality of its birth and death. Understood existentially, birth is not … something past in the sense of something no longer present-at-hand; and death is just as far from having the kind of being of something … not yet present-at-hand but coming along … Factical Dasein exists as born; and, as born, it is already dying, in the sense of being-towards-death. As long as Dasein factically exists, both the ‘ends’ and their ‘between’ *are*, and they are in the only way possible on the basis of Dasein’s being as *care* … As care, Dasein is the ‘between’. "

" Dasein exists as an entity for which, in its Being, that Being is itself an issue. Essentially ahead of itself, it has projected itself upon its potentiality-for-Being before going on to any mere consideration of itself. In its projection it reveals itself as something which has been thrown. It has been thrownly abandoned to the ‘world’, and falls into it concernfully.(1) As care—that is, as existing in the unity of the projection which has been fallingly thrown—this entity has been disclosed as a “there”. As being with Others, it maintains itself in an average way of interpreting—a way which has been Articulated in discourse and expressed in language. Being-in-the-world has always expressed itself, and as Being alongside entities encountered within-the-world, it constantly expresses itself in addressing itself to the very object of its concern and discussing it. The concern of circumspective common sense is grounded in temporality—indeed in the mode of a making-present which retains and awaits. Such concern, as concernfully reckoning up, planning, preventing, or taking precautions, always says (whether audibly or not) that something is to happen ‘then’, that something else is to be attended to ‘beforehand’, that what has failed or eluded us ‘on that former occasion’ is something that we must ‘now’ make up for.(2) "

" It is not necessary that in resoluteness one should explicitly know the origin of the possibilities upon which that resoluteness projects itself. It is rather in Dasein's temporality, and there only, that there lies any possibility that the existentiell potentiality-for-Being upon which it projects itself can be gleaned explicitly from the way in which Dasein has been traditionally understood. The resoluteness which comes back to itself and hands itself down, then becomes the repetition of a possibility of existence that has come down to us. Repeating is handing down explicitly—that is to say, going back into the possibilities of the Dasein that has-been-there. The authentic repetition of a possibility of existence that has been—the possibility that Dasein may choose its hero—is grounded existentially in anticipatory resoluteness; for it is in resoluteness that one first chooses the choice which makes one free for the struggle of loyally following in the footsteps of that which can be repeated. But when one has, by repetition, handed down to oneself a possibility that has been, the Dasein that has-been-there is not disclosed in order to be actualized over again. The repeating of that which is possible does not bring again [Wiederbringen] something that is 'past', nor does it bind the 'Present' back to that which has already been 'outstripped'. Arising, as it does, from a resolute projection of oneself, repetition does not let itself be persuaded of something by what is 'past', just in order that this, as something which was formerly actual, may recur. Rather, the repetition makes a reciprocative rejoinder to the possibility of that existence which has-been-there. But when such a rejoinder is made to this possibility in a resolution, it is made in a moment of vision; and as such it is at the same time a disavowal of that which in the "today", is working itself out as the 'past'. Repetition does not abandon itself to that which is past, nor does it aim at progress. In the moment of vision authentic existence is indifferent to both these alternatives” (437-8). "
