Nature is indifferent to and more powerful than human life
Arrogance can prevent one from accepting vital knowledge.
Ha ha, I am capable of surviving by myself.
Don't travel without a companion, it is very cold.

Humans have the knowledge to survive in the wild with manmade technlogy, but nature can triumph over all efforts.
Although the man understands that fifty degrees below zero is extremely cold, he doesn't understand the danger of such low temperatures in comparison to the dog who instinctually senses the danger of traveling in such temperatures.
Perserverance and ignorance of serious threats is foolish and will be harmful.
Throughout the story, the dog only cares for its own wellbeing and doesn't seek to protect the man, and at the end, with the man dead, the dog quickly leaves to the camp, where it knows there will be food and warmth.
In the man's initial attempt to build a fire, he succeeds and warms himself/ However, when the fire is crucial to his survival he fails to build a fire as his fingers are already frozen, and thus, he succumbs to the cold.
Despite the man's fingers instantly going numb and him beginning to freeze to death, he repeatedly ignores the warning signs and trudges ahead, with ideas of turning back or taking shelter never entering his consciouness.
