Think the headless way is too visual? Then it's time for one last 'blind' experiment:
"This experiment answers a question which I'm sure has been in many of your minds. You say, 'This is terribly visual. How would you show this to a blind man? If it's only accessible to vision, it can't be very profound.' Our last experiment is to check up whether this is available to senses other than vision. You are the authority. Don't believe a thing Douglas says. I shall ask questions; you must supply your own answers." — Douglas Harding
