"But government! You'd need government! How about public works — wars — taxes?"
"No wars on Mars, in spite of being named after the War God. No point in wars here; the population is too thin and too scattered, and besides, it takes the help of every single community to keep the canal system functioning. No taxes because, apparently, all individuals cooperate in building public works. No competition to cause trouble, because anybody can help himself to anything. As I said, with a perfect race government is entirely unnecessary."
"And do you consider the Martians a perfect race?" asked the captain grimly.
"Not at all! But they've existed so much longer than man that they're evolved, socially at least, to the point where they don't need government. They work together, that's all." Jarvis paused. "Queer, isn't it — as if Mother Nature were carrying on two experiments, one at home and one on Mars. On earth it's trial of an emotional, highly competitive race in a world of plenty; here it's the trial of a quiet, friendly race on a desert, unproductive, and inhospitable world. Everything here makes for cooperation. Why, there isn't even the factor that causes so much trouble at home — sex!"
"Huh?"
"Yeah: Tweel's people reproduce just like the barrels in the mud cities; two individuals grow a third one between them. Another proof of Leroy's theory that Martian life is neither animal nor vegetable. Besides, Tweel was a good enough host to let him poke down his beak and twiddle his feathers, and the examination convinced Leroy."
