“It is true that no nation, and no historian can tell a story that completely encompasses every aspect of the truth. But it is not true that just because all narratives are constructed, that they are equally far from the truth. The Earth is neither a perfect sphere nor a flat disk, but the model of the sphere is much closer to the truth. ...The fact that we can never have complete, perfect knowledge does not absolve us of the moral duty to judge and take a stand against evil.”
