The Predatory Nature of Human Existence Of Mice and Men teaches a grim lesson about the nature of human existence.
Nearly all of the characters, including George, Lennie, Candy, Crooks, and Curley’s wife, admit, at one time or another, to having a profound sense of loneliness and isolation.
Having just admitted his own vulnerabilities—he is a black man with a crooked back who longs for companionship—Crooks zeroes in on Lennie’s own weaknesses.
In scenes such as this one, Steinbeck records a profound human truth: oppression does not come only from the hands of the strong or the powerful.
In sharing his vision of what it means to be human, Steinbeck touches on several themes: the nature of dreams, the nature of loneliness, man's propensity for cruelty, powerlessness and economic injustices, and the uncertainty of the future.
Nature of Dreams In essence, is as much a story about the nature of human dreams and aspirations and the forces that work against them as it is the story of two men.
Initially, the obstacles are difficult but not insurmountable: staying out of trouble, not spending money on liquor or in bordellos, and working at the ranch long enough to save the money for a down payment. Some of these obstacles are external (the threat from Curley's wife and Curley's violence, for example, as well as the societal prejudices that plague each man); others are internal (such as Lennie's strength and his need to touch soft things).
For George, the greatest threat to the dream is Lennie himself; ironically, it is Lennie who also makes the dream worthwhile.
Humans give meaning to their lives — and to their futures — by creating dreams.
Without dreams and goals, life is an endless stream of days that have little connection or meaning.
