“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 ” To Build a Fire” by Jack London
