"Ideas are like beards. Men don't have them until they grow up. Somebody said that, but I can't remember who." "Voltaire," the younger man said. He rubbed his chin and smiled, a cheerful, unaffected smile. "Voltaire might be off the mark, though, when it comes to me. I have hardly any beard at all, but have loved thinking about things since I was a kid." His face was indeed smooth, with no hint of a beard. His eyebrows were narrow, but thick, his ears nicely formed, like lovely seashells. "I wonder if what Voltaire meant wasn't ideas as much as meditation," Tsukuru said. The man inclined his head a fraction. "Pain is what gives rise to meditation. It has nothing to do with age, let alone beards."
