Writing Quote: Alien Societies in Science Fiction

Stephen H. Doyle, in Habitable Planets for Man, attempted to estimate the abundance of planets in which human beings could live without life-support systems such as domes or spacesuits. He estimated that there were something like 600 million human-habitable planets in our galaxy alone. Other galaxies should have comparable numbers.
