You see them? You see them? You see the things that float and flop about you and through you every moment of your life? You see the creatures that form what men call the pure air and the blue sky? Have I not succeeded in breaking down the barrier; have I not shewn you worlds that no other living men have seen?
The eye which turns from a white object in the light of the sun and goes into a less fully lighted place will see everything as dark.
People talk to people who perceive nothing, who have open eyes and see nothing; they shall talk to them and receive no answer; they shall adore those who have ears and hear nothing; they shall burn lamps for those who do not see.
