Time present and time past.
Are both present in time future,
And time future contained in time past.
If all the time is eternally present
All time is unreedemable.
What might have been is an abstraction
Remaining a perpetual possibility
Only in a world of speculation.
What might have been and what has been
Point to one end, which is always present.
T.S. Eliot (1935). From “Burnt Norton” in No.1. Four quartets.
everything is contained in now
