There's a nearly universal folklore about the evil eye. New Zealand warriors ate the eyes of slain kings because in those eyes, they believed, resided the divine. The Great Seal of the United States, reproduced on every dollar bill, features the all-seeing eye of God. Our language places a high value on sight. Seeing is believing.
Great leaders are visionaries.
Our technology mimics the reliance on sight. The stores use optical scanners to see which items we want to buy. Try to imagine an olfactory scanner sniffing the identity and prices of soup cans and bunches of celery as they pass along the check-out line. None of the ancient folklore or language or reverence for the religious symbolism of the eye can match what scientists have discovered about vision in the last 125 years. In one study, scientists removed the temporal lobes of monkeys.
