In Book III, Mr. Barnstaple longs to stay in Utopia, but when he asks how he can best serve Utopia, he is told that he can do this "by returning to your own world". Regretfully he accepts, and ends his month-long stay in Utopia. But he brings with him back to Earth a renewed determination to contribute to the effort to make a terrestrial Utopia: "e belonged now soul and body to the Revolution, to the Great Revolution that is afoot on Earth; that marches and will never desist nor rest again until old Earth is one city and Utopia set up therein. He knew clearly that this Revolution is life, and that all other living is a trafficking of life with death."
