Obama stands in the tradition of King by appealing to the founding vision of America and calling America to fulfill that vision. And he is right to believe that there can only be a vision for the future if that vision is rooted in memories that can engender and sustain such a vision. And he was politically wise to argue that we must reject the Bush legacy because it departs from the best of American traditions, the best of American promise. But what is that promise? What, beyond those three foundational words, is the heart of that tradition? If vision is rooted in memory, are some memories better than others? Might there be some memories that need to be re-evaluated if we are to proceed with hope and an alternative vision?
