There was a gap between the general public and Arinori since he had a radical idea, and therefore he was criticized and called "Meiroku no yurei (which is a pun for his name "有礼" that can also be pronounced "yurei") (the ghost of the Meirokusha)".
また急進的な考えを持っていたので大衆とのギャップが出来てしまい、国民から揶揄され「明六の幽霊（有礼）」と呼ばれた。
