Now that you come to think of it, you can recall perfectly well that
Columbus discovered America in 1492; that your house is painted white;
that it rained a week ago today. But where were these once-known facts,
now remembered so easily, while they were out of your mind? Where did
they stay while you were not thinking of them? The common answer is,
'Stored away in my memory.' Yet no one believes that the memory is a
warehouse of facts which we pack away there when we for a time have no
use for them, as we store away our old furniture.
