 My idea would be to decompose a man, so to speak, and examine what he derives from each of the senses he possesses. I recall how I was once concerned with this sort of metaphysical anatomy, and had found that of all the senses, the eye was the most superficial, the ear the most proud, smell the most pleasurable, and taste the deepest, most philosophical sense. It would be a pleasant society, I think—one composed of five people, each of whom only possessed one sense. They would undoubtedly call each other mad, and I leave you to imagine how right they might be. Yet this is an image for what happens to everyone: one only has one sense and one judges on everything.
