The Eyes Have It by Philip K. Dick, Science Fiction, Fantasy, Adventure (Paperback) (ISBN-13: 9781606645147)

Theoretically, you could find this type of humor anywhere. But only a topflight science-fictionist, we thought, could have written this story, in just this way. . . . Start here: It was quite by accident I discovered this incredible invasion of Earth by lifeforms from another planet. As yet, I haven't done anything about it; I can't think of anything to do. I wrote to the Government, and they sent back a pamphlet on the repair and maintenance of frame houses. Anyhow, the whole thing is known; I'm not the first to discover it. Maybe it's even under control. "All of his work starts with the basic assumption that there cannot be one, single, objective reality", writes science fiction author Charles Platt.
