Dick's fiction calls up our basic cultural assumptions, requires us to reexamine them, and points out the destructive destinations to which they are carrying us. The American Dream may have succeeded as a means of survival in the wilderness of early America; it allowed us to subdue that wilderness and build our holy cities of materialism. But now, the images in Dick's fiction declare, we live in a new kind of wilderness, a wasteland wilderness, because those cities and the culture that built them are in decay. We need a new American dream to overcome this wasteland.
Philip K. Dick
