Although Lennie is among the principal characters in Of Mice and Men, he is perhaps the least dynamic. He undergoes no significant changes, development, or growth throughout the novel and remains exactly as the reader encounters him in the opening pages. Simply put, he loves to pet soft things, is blindly devoted to George and their vision of the farm, and possesses incredible physical strength. Nearly every scene in which Lennie appears confirms these and only these characteristics.
Although Steinbeck's insistent repetition of these characteristics makes Lennie a rather flat character, Lennie's simplicity is central to Steinbeck's conception of the novel. Of Mice and Men is a very short work that manages to build up an extremely powerful impact. Since the tragedy depends upon the outcome seeming to be inevitable, the reader must know from the start that Lennie is doomed, and must be sympathetic to him. Steinbeck achieves these two feats by creating a protagonist who earns the reader's sympathy because of his utter helplessness in the face of the events that unfold. Lennie is totally defenseless. He cannot avoid the dangers presented by Curley, Curley's wife, or the world at large. His innocence raises him to a standard of pure goodness that is more poetic and literary than realistic. His enthusiasm for the vision of their future farm proves contagious as he convinces George, Candy, Crooks, and the reader that such a paradise might be possible. But he is a character whom Steinbeck sets up for disaster, a character whose innocence only seems to ensure his inevitable destruction.
A large, lumbering, childlike migrant worker. Due to his mild mental disability, Lennie completely depends upon George, his friend and traveling companion, for guidance and protection. The two men share a vision of a farm that they will own together, a vision that Lennie believes in wholeheartedly. Gentle and kind, Lennie nevertheless does not understand his own strength.
