If “modern art” is “the object that occupies an empty space on a wall at the Museum of Art”, then, I suppose, there must be a reason for that empty space to be affiliated with “art”. There must have been a “something” that once occupied that “empty space on the wall that orients the desires of art lovers”.
The “something” that “once occupied that empty space on the wall” has either been forgotten or placed under erasure, because not even the experts remember or acknowledge what that “something” was.
Similarly, if “Nothing” is “the object that that occupies the empty space in our heart of hearts”, then there must have been a “something” that once occupied “the empty space in our hearts of hearts”.
Similarly, the “something” that “once occupied the empty space in our heart of hearts” has either been forgotten or placed under erasure.
Perhaps, that forgetting and placing under erasure is scandalous.
