Ian McEwan’s Nutshell presents an unusual narrator an unborn child who observes the world from inside the womb. This novel explores how moral awareness can exist even before birth. Through the unborn child’s reflections, McEwan raises important questions about ethics, responsibility, and human choice. Although physically confined, the narrator develops a sharp understanding of good and evil by listening to conversations and reacting emotionally to events around him.This study examines how moral reasoning operates in Nutshell through the consciousness of the unborn narrator. The novel shows that ethical judgment does not depend on age or experience alone. Instead, it grows from awareness, empathy, and reflection. The unborn child struggles with feelings of fear, guilt, and helplessness as he becomes aware of a planned crime. His inability to act highlights the tension between moral knowledge and moral action.
