Outstanding examples of genius - a Mozart, a Shakespeare, or a Carl Friedrich Gauss - are markers on the path along which our species appears destined to tread.

The seemingly insuperable difficulties of deep-space travel suggest an intention to keep us fixed at home in our own solar system, and the physical nature of our part of the Universe, as well as the basic rules of physics and chemistry, have a warning look about them, like barriers designed to isolate intelligent life.
