Time present and time past are both perhaps present in time future,
and time future contained in time past.
If all time was eternally present, all time is unredeemable.
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.
Footfalls echo in the memory,
down the passage which we did not take,
forwards the door we never opened,
into the rose garden.
