While the powerlessness of the laboring class is a recurring theme in Steinbeck`s work of the late 1930s, he narrowed his focus when composing "Of Mice and Men", creating an intimate portrait of two men facing a world marked by petty tyranny, misunderstanding, jealousy, and callousness. But though the scope is narrow, the theme is universal; a friendship and a shared dream that makes an individual`s existence meaningful.
