Why Shadows Were Invented

In 'From These Wilds Beyond Our Fences,' Bayo Akomolafe points out that when Seventeenth-century physicist Francesco Grimaldi directed a focused ray of sunlight in a dark room, managing the ray so that it struck a thin rod and produced a shadow on a screen, he proved that light behaves in unexpected ways. In fact, light is only one side of a whole,like yin and yang. Thus "darkness is not the absence of light -- it is the very dance of light...Light and dark are not opposites or estranged cosmic forces that one side must defeatfor there are no 'sides.'"
