Salinger’s novel of growth in the novel. Through the narrator Buddy’s fragmented memory of his brother Seymour, the work brings together the tragedy of Seymour Grass. The hopeless exploration of the spirit, the loss of collective belonging, and the exclusion of others as the mainstream society indirectly pushed him to the abyss of self-destruction. This article will take the image of Seymour as an entry point, mainly through the postmodern ethical analysis of personal and social factors that cause the predicament of others in post-modern society.
