As he walked along the hot road toward the walls of Bou Noura he kept his head down, seeing nothing but the dust and the thousands of small sharp stones. He did not look up because he knew how senseless the landscape would appear. It takes energy to invest life with meaning, and at present this energy was lacking. He knew how things could stand bare, their essence having retreated on all sides to beyond the horizon, as if impelled by a sinister centrifugal force. He did not want to face the intense sky, too blue to be real, above his head, the ribbed pink canyon walls that lay on all sides in the distance, the pyramidal town itself on its rocks, or the dark spots of oasis below. They were there, and they should have pleased his eye, but he did not have the strength to relate them, either to each other or to himself, he could not bring them into any focus beyond the visual. So he would not look at them.
From Paul, Bowles’s 1949 novel The Sheltering Sky. I like the passage; Bowles shows here that to be human is to invest an aesthetic (and simultaneously anesthetic) viewpoint into one’s daily life—and that to invest in this viewpoint is to calculate psychic and emotional costs and payoffs.
