" As Marcel Proust understood, memory is not exclusively or even predominantly visual. It is synesthetic, a combination and even a confusion of the senses that no simple image can reach or encapsulate. A photograph can act as a spur to memory, it can yield treasures, like looking under your bed and finding the baseball card you were certain you lost. But an image stands mute before the inexpressible delicacy, horror, humor, and associative complexity of our experience. "
