[with television] You are drawn into that tube, as 
an inner trip. You’re totally involved. You have no 
objectivity, no distance. And it is acoustic. It 
resonates. But this is a hidden ground, because 
superficially people think they’re looking at a visual 
program. And they’re not. They’re not looking at 
all—they’re absorbed, involved in a resonating 
experience. And it is not objective, it is entirely 
subjective.
