It's quite difficult to comprehend.
One moment's he's Benjy, the next he's Benjamin, and it ends with him being Maury. What?
Also, I don't know why Quentin's talking about incest and why the Father gave him a pistol.
Finally, what does it mean when Benjy says 'he can't stop' but he isn't crying?
Anyhow, memorable quote:
“When Father gave it to me he said, Quentin, I give you the mausoleum of all hope and desire; it's rather excrutiatingly apt that you will use it to gain the reducto absurdum of all human experience which can fit your individual needs no better than it fitted his or his father's. I give it to you not that you may remember time, but that you might forget it now and then for a moment and not spend all your breath trying to conquer it. Because no battle is ever won he said. They are not even fought. The field only reveals to man his own folly and despair, and victory is an illusion of philosophers and fools.”
