I still visualize the words etched into a granite slab on a wall of Elmina, a stately castle on the coast of Ghana, constructed in 1482 by the Portuguese:
IN EVERLASTING MEMORY OF THE ANGUISH OF OUR ANCESTORS. MAY THOSE WHO DIED REST IN PEACE. MAY THOSE WHO RETURN FIND THEIR ROOTS. MAY HUMANITY NEVER AGAIN PERPETUATE SUCH INJUSTICE AGAINST HUMANITY. WE, THE LIVING, VOW TO UPHOLD THIS.
