I don't have much to say about this altough I have made a very comprehensive reading of these two authors for they are far beyond me in their greatness.

All I could say in simplest terms:

*Hemingway: His literary genius nourished on the world outside the boundaries of America. He wrote for the citizen of the world.

*Steinbeck: Nourished on the sources of his own land. He wrote mainly for the people of America.

Their style:

Hemingway: More condenced and less local.

Steinbeck: More fine local touches/provincialism and less condenced.

I would be appreciated to hear your say on this issue.
