Motifs are recurring structures, contrasts, and literary devices that can help to develop and inform the text's major themes.
Loneliness and Companionship
Many of the characters admit to suffering from profound loneliness. George sets the tone for these confessions early in the novella when he reminds Lennie that the life of a ranch-hand is among the loneliest of lives. Men like George who migrate from farm to farm rarely have anyone to look to for companionship and protection. As the story develops, Candy, Crooks, and Curley’s wife all confess their deep loneliness. The fact that they admit to complete strangers their fear of being cast off shows their desperation. In a world without friends to confide in, strangers will have to do. Each of these characters searches for a friend, someone to help them measure the world, as Crooks says. In the end, however, companionship of his kind seems unattainable. For George, the hope of such companionship dies with Lennie, and true to his original estimation, he will go through life alone.
Strength and Weakness
Steinbeck explores different types of strength and weakness throughout the novella. The first, and most obvious, is physical strength. As the story opens, Steinbeck shows how Lennie possesses physical strength beyond his control, as when he cannot help killing the mice. Great physical strength is, like money, quite valuable to men in George and Lennie’s circumstances. Curley, as a symbol of authority on the ranch and a champion boxer, makes this clear immediately by using his brutish strength and violent temper to intimidate the men and his wife. Physical strength is not the only force that oppresses the men in the book. It is the rigid, predatory human tendencies, not Curley, that defeat Lennie and George in the end. Lennie’s physical size and strength prove powerless; in the face of these universal laws, he is utterly defenseless and therefore disposable.
