I'll stress that ignorance.
"Empirical Scene."
"We saw a grand piano fall off a roof as if in slow motion,
and hit the sidewalk without a sound.
As we laughed at the philosophical implications
and went down into the subway where
the noise of all crashing pianos is
kept on permanent performance in full volume.
So at least we weren't deaf or in an inconsistent universe.
It had been like the beginning of a silent movie,
but we didn't know that we were in it,
so we never found out what happened.
We who didn't hear the grand piano."
