I just finished Mack Reynolds’ Ultima Thule, a futuristic account of interplanetary exploration/occupation. In the story, groups go out with their ideals, take a planet for their own, and endeavor to live within their belief system. They are all looking for the Ultima Thule, that place beyond what is known, with a desire to attain “unattainable” goals. It is westward expansion on a different playing field. No matter what the frontier, no matter what the goal, both are bound to be altered, subverted, evolved, and ultimately unrecognizable.
