The condition or quality of lacking affection, kindness, or concern for others; emotional detachment or indifference.
From Greek 'a-' (not) and 'phile' (loving, friendly), originally appearing in psychological texts. Rare in modern usage but reflects ancient Greek philosophical concepts about emotional states.
While most people know about 'apathy' (not feeling), 'aphelia' is the even rarer term for when someone truly lacks the ability to feel warmth toward others—a distinction lost in modern English.
