It is always interesting to read older science fiction to see how the author envisions the future yet carries along habits and things from the present, like people in the future still printing on paper, reading newspapers, and driving cars that fly in the same manner as we drive cars today. Still, this title is one of my favorites despite or perhaps because of its idiosyncrasies. The philosophy of the future, rigidly enforced relativism, is also a leap for the author, spelling out clearly where he thinks we are headed.
