What a feeble thing intelligence is, with its short steps, its waverings, its pacings back and forth, its disastrous retreats! Intelligence is a mere instrument of circumstances. There are people who say that intelligence must have built the universe - why, intelligence never built a steam-engine! Circumstances built a steam-engine. Intelligence is little more than a short foot-rule by which we measure the infinite achievements of Circumstances.
~ F. Scott Fitzgerald
