1. Disillusionment with phoniness: Holden sees school as a breeding ground for "phonies," people who are insincere and superficial. He finds his classmates and teachers hypocritical and unauthentic, unable to connect with genuine emotions and experiences.
2. Lack of intellectual stimulation: Holden is intelligent and perceptive, but he feels stifled by the rigid curriculum and the pressure to conform. He finds the material uninteresting and feels like he's being forced to learn things that hold no value to him.
3. Fear of growing up: Holden's rebellion against school is partly a rebellion against growing up. He longs for innocence and simplicity, and sees school as a symbol of adulthood and the loss of those qualities.
4. Feeling of isolation: He struggles to connect with his peers and feels misunderstood by them. He yearns for authentic connections but finds himself surrounded by people he considers phony, further deepening his sense of loneliness.
5. Disdain for the "establishment": Holden's disdain extends beyond school to encompass the entire establishment, which he sees as corrupt and hypocritical. His rebellion against school is a form of rebellion against the larger society he feels alienated from.
6. Personal trauma: Holden's experiences with death, particularly the loss of his younger brother Allie, contribute to his disillusionment and his desire to protect children from the harsh realities of the world. He sees school as part of the system that leads to the corruption of innocence.
It's important to note that Holden's hatred of school is not simply a straightforward rejection of education. He is deeply troubled by his own inner turmoil, and his hostility towards school is a manifestation of his larger existential angst and struggle to find meaning in a world he perceives as phony and corrupt.
