Cavor explains war to Grand Lunar
Stranded alone on the Moon, the scientist Cavor is brought before the Grand Lunar, the Selenites' enormous-brained ruler, and innocently describes human history: nations, armies, and men killing one another by the thousand for territory and honour. The Grand Lunar concludes that such a species, now able to travel to the Moon, is dangerous, and the Selenites cut off Cavor's radio transmissions to Earth before he can send the cavorite formula home. The episode is a test case for the claim that full disclosure of your culture's norms to a more rational observer can be self-condemning.
