Rule Golden and Other Stories

Another excellent collection of SFWA Grandmaster Damon Knight's always-excellent stories-five novellas in this case, generally circling around "the great unsolved problem of politics: how to keep the bastards from grinding you down." Rule Golden-what if the Golden Rule were enforced in reverse by some force-the bad things you do to others are done to you? Natural State-are cities doomed by genetic engineering? Double Meaning-a race against time to find a shape-shifting alien spy. The Earth Quarter-why did the aliens on a remote planet keep all the humans locked inside a section of the city? The Dying Man-what would it be like to be immortal... then suddenly find out you'd become mortal?
