This paper examines how forgiveness and reconciliation are achieved by different and opposed people, such as perpetrators and victims in a conflict. An investigation into the concept of forgiveness is first needed, to further an understanding of forgiveness in relation to the concept of reconciliation. While comparing these concepts, this study re-examines and analyzes how Arendt conceptualizes the relationship between them, making reference to her Denktagebuch, The Human Condition, and Eichmann in Jerusalem. It is found that forgiveness was regarded as a more negative concept than reconciliation in her early work, whereas the meaning of forgiveness came closer to the concept of reconciliation in her later work.
