not yet, n.All

The Not-yet (n.) belongs ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠to the fruit itself: unripeness is not something missing from it but the fruit as it ripens — and so, too, each of us already is our own not-yet.

The Not-yet (n.) of ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠Dasein is not like the moon's missing quarter, which is only hidden from our view; it 'is' not yet actual at all — Dasein must itself become what it is not yet.
