A Heritage of Stars — Clifford D. Simak

A man hunts for lost knowledge in a future society that's reverted to a primitive tribal state in this novel by the author of Way Station.

More than a thousand years have passed since humankind intentionally destroyed its treacherous technology, choosing to revert back to a primitive tribal state. In this society the rusting brain cases of long-inert robots are considered trophies, and the scant knowledge that has survived is doled out to an inquisitive few in monastery-like “universities.” It is at one such center of learning that young Tom Cushing first reads of the legendary “Place of Going to the Stars,” rumored to exist on a high butte somewhere in the western part of the land. Driven by enthusiasm and an insatiable need to track the myth to its source, Tom sets out on an amazing trek across what was once called “America,” teaming up with a witch, the world's last remaining robot, and other odd companions. But all the astonishing discoveries and dangers they encounter along the way will pale before the revelations that await them at journey's end.
