 This observation brings us to a final way in which moral questions arise in the context of honest history. The crimes of the past have consequences in the present. The facts of trans-Atlantic slavery continue to have consequences for millions of descendants of the men and women who were transported from Africa to the Americas; the facts of the Rwandan genocide have consequences for the living victims of these mass killings and their kin; and the fact of colonial exploitation of the Congo or southern Africa has consequences for the current poverty of much of Africa. Does knowledge of the crimes of the past create for the current generation an obligation of engagement in contributing actively to healing those wounds in the present and preventing their recurrence in the future? Does “truth and reconciliation” require more than simply recognizing ugly truths about the past? Does it require that we act differently, individually and collectively? It is of course a tragic and immutable reality of the human condition that the past cannot be changed; the murdered cannot be unmurdered, and the primary perpetrators of horrific crimes within a few generations are certainly beyond the reach of justice. The future is deeply contingent, while the past is fixed and unchangeable. But does this immutability imply that the present generation has no obligations created by past crimes? Or rather, does knowing the truth about our past create for us the obligation to learn from those tragic human actions how to avoid such crimes in the future? Does honest knowledge of the human crimes of the past bring with it an obligation to strive in good faith to address the consequences of those crimes in the present? Finally, can knowledge of history help us to become more empathetic, more just, and more farsighted in our dealings with each other in the grand affairs that make up future history? One would hope so; and perhaps this is the most pressing moral obligation of all that is created by our recognition of our own historicity.
