Aldous Huxley

"Thought is the brain's three milliards
Of cells from the inside out.
Billions of games of billiards
Marked up as Faith and Doubt.

"My faith, but their collisions;
My logic, their enzymes;
Their pink epinephrine, my visions;
Their white epinephrine, my crimes.

"Since I am the felt arrangement
Of ten to the ninth times three,
Each atom in its estrangement
Must yet be prophetic of me."
