“The subjective response... when a Philip Dick book has been finished and put aside is that, upon reflection, it does not seem so much that one holds a memory of the story; rather, it is the after effects of a poem rich in metaphor that seem to remain.

This I value, partly because it does defy a full mapping, but mainly because that which is left of a Phil Dick story when the details have been forgotten is a thing which comes to me at odd times and offers me a feeling or a thought; therefore, a thing which leaves me richer for having known it.

- Roger Zelazny in his introduction to Beyond Lies the Wub”
