A double concept
Night approached and the wall became even more beautiful. The cherry blossoms released a faint pink glow that illuminated the entire environment, making the wall splendid. Kayden still hadn't gotten around to understanding his concept.
"Have you ever wondered the difference between a human being and a beast?" Kayden didn't even blink to respond. He had already gotten used to the old man.
"Humans are rational beings." That was the normal response.
"What defines rationality? Are we smarter than them? Does this give us the right to enter their territories and kill them for monetary purposes? In that case, if a race much more intelligent than the human race invades us, can they treat us like cattle? The difference in intellect would make us appear irrational to them."
