A figure with childlike innocence but immense physical strength, based on a real person Steinbeck had met, symbolizing humankind's animal nature and inevitable doom
George is a radical leader attempting to lead Lenny, a symbol of the masses, to a utopia of owning a farm, but Lenny's destructiveness causes the utopia to fail
George is simply a worker trying to improve his lot in life by becoming a landowner, but this ambition collapses
From a psychoanalytical perspective, Lenny is George's shadow self, a scapegoat for his own faults
Steinbeck's principal aim is to show that without the civilizing forces of companionship, we become almost like animals feeding off others and spurning the weak
Exemplified in the way characters represent varying forms of prejudice - physical disability, gender, racial, mental disability, social class
The story shows the power for society formed by nature's lower forces and the power that this has to destroy finer human aspiration
Candy hopes to become part of George and Lenny's family, and their rise above animal nature is consistent with their rise above mere self-gratification and concern for the shared future rather than animalistic survival from one day to the next
