It is not enough to say that we cannot know or judge because all the information is not in. The process of gathering knowledge does not lead to knowing. A child's world spreads only a little beyond his understanding while that of a great scientist thrusts outward immeasurably. An answer is invariably the parent of a great family of new questions. So we draw worlds and fit them like tracings against the world about us, and crumple them when they do not fit and draw new ones.

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.
