Kokoro, by Natsume Soseki (paragraph #913)

「先生は癇性ですね」とかつて奧さんに告げた時、奧さんは「でも着物などは、それ程氣にしないやうですよ」と答へた事があつた。それを傍に聞いてゐた先生は、「本當をいふと、私は精神的に癇性なんです。それで始終苦しいんです。考へると實に馬鹿々々しい性分だ」と云つて笑つた。精神的に癇性といふ意味は、俗に神經質といふ意味か、又は倫理的に潔癖だといふ意味か、私には解らなかつた。奧さんにも能く通じないらしかつた。

translation

When I once told Mrs. Oku, "You're hot-tempered, aren't you?", Ms. Okusan replied, "But you don't seem to care about kimonos." Sensei, who was listening beside him, said with a laugh, "To tell you the truth, I'm mentally hot-tempered. That's why I'm always in pain. When I think about it, my personality is really silly." . I didn't understand if what was meant by "psychologically hot-tempered" was, in common terms, "psychic" or "ethically clean-cut". Oku-san didn't seem to be able to get through either.
