Sight is a highly intellectual sense. Any other sense is more instinctual and direct, maybe even more effective. Sight became our dominant sense long ago; maybe it’s always been dominant in humans. But some mental processes don’t necessarily need a high degree of intellectualization to work properly. The outcome of some of these processes is more dynamic and powerful if less of the rational side is involved. Images are not proustian madeleines. They’re too stylized for that involuntary act of memory and they rely more on reason as memory retrievers. Their effects on our reminiscing abilities is partly weakened and corrupted by rational intellect.
