Among men, it seems, historically at any rate, the processes of coordination and disintegration follow each other with great regularity, and the index of the coordination is the measure of the disintegration which follows. There is no mob like a group of well-drilled soldiers when they have thrown off their discipline. And there is no lostness like that which comes to a man when a perfect and certain pattern has dissolved about him. There is no hater like one who has greatly loved.

The book is very different in tone from Steinbeck's amoral and ecological stance in earlier works like Tortilla Flat and Cannery Row. The story is about two traveling ranch workers George and Lennie trying to work up enough money to buy their own farm/ranch. Soon after he began work on East of Eden (1952) which he considered his best work.
