An attempt at explication

During several points in A Void, especially in the beginning, Anton has several moments where he temporarily goes literally insane, and begins to unravel himself from reality. At one point he begins to think about a book that had been boughten for him when he was younger, and begins to go off on a tangent that takes him entirely away from the story. Anton tells of La Croix du Sud, a story about a man named Ishmail, who was got stranded on what he believed to be an abandoned island. He tells of how Ishmail created himself his own one-man society in which he lived. However, it continues to talk about when other people landed on the island, and how Ishmail was left ignored, as if he has sunken into his own private void, where no others could, or wanted to see him.
There are several points where Anton talks about “voids”, how they exist everywhere, or how he feels as if he himself is falling into one which he will never be able to escape. In the last passage before Anton disappears, it reads, “... That’s what would stop Anton Vowl from dying... But how to construct it all in just that instant in which is born a Void?”
The “Void” could be referring to many things, the most obvious of which is the void borne from the missing letter “e” from the entire work. When looking at Perec’s life, it would suggest a void caused from losing both his mother and father when he was young, (mother and father both being words he is incapable of saying in his book).
