So, basically, Holden cracks in the last section of the novel, starting when Luce leaves him. I'm guessing it was probably due to the lack of ability for social interaction or feeling alone, but Holden gets drunk as heck, bursts senselessly into tears, and heads to his adored duck pond where he remembers Allie's funeral and decides that when he dies, he wants to be tossed into the river. Also, Holden seems kinda interested in vanishing things in life too all of a sudden. Kinda like how all the ducks in the pond randomly left.
And then with Phoebe, Holden gets a bit better. But then she demands to know if he actually likes ANYTHING and he starts thinking about the kid who committed suicide in his turtleneck and how
I also found out what the title means. The Catcher in the Rye is Holden himself. I did research on rye, and apparently a rye field is the symbol of childhood because the rye plant is so high kids can't see beyond it. The catcher, or Holden, has already ran out of the field and fallen over the cliff or whatever to adulthood, and no one caught him. Therefore, he is living a crappy life of loneliness, alcohol, and sex. Hence, he wants to catch the other kids and save them from adulthood. For instance, Holden really wants to protect children from knowledge of sex. One part that shows this is when he rubs the words “f*** you” off the school wall because he is scared that someone will explain to the kids what it means. Holden really is quite the decent guy after all, in some ways.
As for the ending, it has a climax but it is more hidden, I feel. It's not like Harry Potter where you know where the climax is right away. I think it starts the day after Holden is at Mr. Antolini's house and runs away. I think it starts at the place where Holden starts to focus on the kids in the streets and where he he calls to Allie and begs to let him cross the road. Holden is then, officially insane and the reader knows it, if they haven't already figured it out.
Since Holden obviously feels disconnected from life, he decides to run away, only to be stopped by Phoebe. I wondered vaguely if she knew he was crazy, and purposely wanted to go with Holden for his own safety, or was just being a stubborn little child. Anyhow, the story ends with Holden at the carousel, watching Phoebe, and feeling overjoyed about the children around him, and how innocenct they are.
At this point, I felt something bigger happened, like maybe Holden cracked and had a giant fit of anger or whatever. In chapter 26, I got the impression he was at an institution for the mentally ill or whatnot and had just told his tale to the doctor or psychologist. However, Holden seemed much more at peace in the last chapter as well, more so than anywhere else in the book. After that, I did more research:
The Catcher in the Rye is, in a way, a perfect biography of J.D. Salinger's own life.
