Expanding to enwrap a world, collapsing to prison up an atom:
As, by night, thine irritable eyes may have seen strange changing figures,
Now a wheel, now suddenly a point, a line, a curve, a zigzag,
A maze ever altering, as the dance of gnats upon a sunbeam,
Swift, intricate, neither to be prophesied, nor to be remembered in succession,
So, the mind of a man, single, and perpetually moving,
Flickereth about from thought to thought, changed with each idea;
For the passing second metamorphosed to the image of that within its ken,
And throwing its immediate perceptions into each cause of contemplation.
It shall regard a tree; and unconsciously, in separate review,
