Umwillen seiner selbst (vide umwillen)
The “ahead-of-itself” is grounded in the future. In the “Being-already-in …”, the character of “having been” is made known. “Being-alongside …” becomes possible in making present. While the “ahead” includes the notion of a “before”, neither the ‘before’ in the ‘ahead’ nor the ‘already’ is to be taken in terms of the way time is ordinarily understood; this has been automatically ruled out by what has been said above. With this ‘before’ we do not have in mind ‘in advance of something’ [das “Vorher”] in the sense of ‘not yet now – but later’; the ‘already’ is just as far from signifying ‘no longer now – but earlier’. If the expressions ‘before’ and ‘already’ were to have a time-oriented [zeithafte] signification such as this (and they can have this signification too), then to say that care has temporality would be to say that it is something which is ‘earlier’ and ‘later’, ‘not yet’ and ‘no longer’. Care would then be conceived as an entity which occurs and runs its course ‘in time’. The Being of an entity having the character of Dasein would become something present-at-hand. If this sort of thing is impossible, then any time-oriented signification which the expressions we have mentioned may have, must be different from this. The ‘before’ and the ‘ahead’ indicate the future as of a sort which would make it possible for Dasein to be such that its potentiality-for-Being is an issue. Self-projection upon the ‘for-the-sake-of-oneself’ is grounded in the future and is an essential characteristic of existentiality.The primary meaning of existentiality is the future. BTMR §65
