QUANTUM GEOMETRY

One of the greatest paeans to recursion occurs in T.S. Eliot’s monumental Four Quartets where at the end of this long, challenging group of poems, wherein he has created a veritable universe of ideas and images, and throughout which the end becomes the beginning and things constantly repeat, Eliot summarily states - - - with the utmost conviction but no finality - - - 

We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time.
Through the unknown, unremembered gate
When the last of earth left to discover
Is that which was the beginning;
At the source of the longest river
The voice of the hidden waterfall
And the children in the apple-tree
Not known, because not looked for
But heard, half-heard, in the stillness
Between two waves of the sea.
Quick now, here, now, always—
A condition of complete simplicity
(Costing not less than everything)
And all shall be well and
All manner of thing shall be well
When the tongues of flames are in-folded
Into the crowned knot of fire
And the fire and the rose are one.
