"Also, it can be considered extremely unlikely that the Nipe civilization—if such it can be called—has any geriatric problem. No, indeed. No old-age pensions, no old folks' homes, no senility. No, nor any specialists in geriatrics, either. When a Nipe becomes a burden because of age, he is ritually murdered and eaten with all due solemnity."
Yoritomo pointed his pipestem at Stanton. "Ah. You frown, my friend. Have I made them sound heartless, without the finer feelings of which we humans are so proud? Not so. When Junior Nipe fails his puberty tests, when Mama and Papa Nipe are sent to their final reward, I have no doubt that there is sadness in the hearts of their loved ones as the honored T-bones are passed around the table."
He put the pipe back in his mouth and spoke around it. "My own ancestors, not too far back, performed a ritual suicide by disemboweling themselves with a long, sharp knife. Across the abdomen—so!—and up into the heart—so! It was considered very bad form to faint or die before the job was done. Nearby, a relative or a close friend stood with a sharp sword, to administer the coup de grace by decapitation. It was all very sad and very honorable. Their loved ones bore the sorrow with great pride."
His voice, which had been low and tender, suddenly became very brisk. "Thank goodness it has gone out of fashion!"
"But how can you be sure they're cannibals?" Stanton asked. "Your argument sounds logical enough, but you can't be basing your theory on that alone."
"True! True!" Yoritomo jabbed the air twice with a rapid forefinger. "Evidence for such a theory would be most welcome, would it not? Very well, I give you the evidence. He eats human beings, our Nipe."
"That doesn't make him a cannibal," Stanton objected.
"Not strictly, perhaps. But consider. The Nipe is not a monster. He is not a criminal. No. He is a gentleman. He always behaves as a gentleman. He is shipwrecked on an alien planet. Around him, he sees evidence in profusion that ours is a technological society. But that is a contradiction! A paradox!
"For we are not civilized! No! We are not rational! We are not sane! We do not obey the Laws; we do not perform the Rituals. We are animals. Apparently intelligent animals, but animals nevertheless. How can this be?
"Ha! says the Nipe to himself. These animals must be ruled over by Real People. It is the only explanation. Not so?"
