“The trouble with him was that he was not able to imagine. He was quick and ready in the things of life, but only in the things, and not in their meanings. Fifty degrees below zero meant 80 degrees of frost. Such facts told him that it was cold and uncomfortable, and that was all. It did not lead him to consider his weaknesses as a creature affected by temperature. Nor did he think about man’s general weakness, able to live only within narrow limits of heat and cold. From there, it did not lead him to thoughts of heaven and the meaning of a man’s life. 50 degrees below zero meant a bite of frost that hurt and that must be guarded against by the use of mittens, ear coverings, warm moccasins, and thick socks. 50 degrees below zero was to him nothing more than 50 degrees below zero. That it should be more important than that was a thought that never entered his head.”
—Jack London, “To Build a Fire” (1908)
