Pleonexia, sometimes called pleonexy, originating from the Greek πλεονεξία, is a philosophical concept which roughly corresponds to greed, covetousness, or avarice, and is strictly defined as "the insatiable desire to have what rightfully belongs to others", suggesting what Ritenbaugh describes as "ruthless self-seeking and an arrogant assumption that others and things exist for one's own benefit".
