a visual affair

We vastly overvalue visual input over other sources of sensual inputs since most of our bandwidth is devoted to vision:

This bias infiltrates both aesthetics and science:

• The set of people you find beautiful will change drastically if you lose your eyesight. (Get a full body massage and you will see what I mean.)

• We explain auditory phenomenon in terms of mathematical metaphors that burgeoned out of visual inputs. There are no mathematical metaphors with auditory origin, and therefore no scientific explanations of visual phenomenon in terms of auditory expressions. Rationality is a strictly visual affair. In fact, the word "idea" has etymological roots going back to the Greek word "Edeo" - "to see". (No wonder why deep neural networks mimicking the structure of our visual system has become so successful in machine learning challenges.)
