The people of Sirius 4 tried to overcome tyranny the old-fashioned way: by force. It turned out to be an imaginary revolution, replacing one violent regime with another. Raymond Douglas Kaliber suggested another way: that free people living by a spirit of non-aggression could live in peace and prosperity with one another.
