A strong piece of supporting evidence for a literary analysis of "A Separate Peace" is the symbolism of the tree at Devon School, which represents the loss of innocence and the transition from childhood to adulthood. The tree serves as a pivotal setting for key events, including the moment that leads to Finny's fall and subsequent injury, symbolizing the fragility of friendship and the impact of betrayal. This imagery reflects the broader themes of war and internal conflict, underscoring the characters' struggles with their identities and moral choices.
