Read the passage from Part 1 of “To Build a Fire.”He was quick and alert in the things of life, but only in the things, and not in the significances. Fifty degrees below zero meant eighty odd degrees of frost. Such fact impressed him as being cold and uncomfortable, and that was all. It did not lead him to meditate upon his frailty as a creature of temperature, and upon man's frailty in general, able only to live within certain narrow limits of heat and cold. . . . Fifty degrees below zero stood for a bite of frost that hurt and that must be guarded against by the use of mittens, ear-flaps, warm moccasins, and thick socks.
The passage says he notices that fifty degrees below zero is cold and thinks about practical ways to protect himself, such as wearing mittens and warm socks. He does not reflect on what the cold means about human vulnerability. This shows his practical nature, not deep insight or spiritual belief.
