General Discussion - Strange translation in the ABC Dictionary

"仁义礼智 (rén-yì-lǐ-zhì) The four cardinal virtues: humanity; justice; propriety, and wisdom"

But from the characters I don't find the same virtues :

仁 benevolence, compassion
义 justice, righteousness
礼 courtesy, manners
智 wisdom

Where does "propriety" come from ???
