In Of Mice and Men, what does Lennie represent? How does he represent "the inarticulate and powerful yearning of all men"?

Lennie Small, because of his mental limitations, cannot
articulate his deepest needs and desires in language that expresses and explains them
specifically, but his deepest and most powerful yearnings are evident throughout the
novel. Lennie longs for the safety and security of a home that cannot be taken away from
him, a place where life can be fulfilling and free of anxiety. For him, this desire is
expressed as "living off the fat of the land" in a place where, finally, he
belongs.

As migrant workers, George and Lennie are members
of the dispossessed, men without homes who have no place in society and who do not
belong wherever they may be. They are poor and trapped in their poverty. Lennie's dream
of the farm, although he cannot discuss it except in the most elemental terms,
represents the universal human yearning for freedom, security, spiritual fulfillment,
and human dignity.
