What are some quotations about the traveler in "To Build a Fire" by Jack London?

I am not sure what kind of quotations you need, but I have put some into categories below:

Characteristics of the man:

But all this—the distant trail, no sun in the sky, the great cold, and the strangeness of it all—had no effect on the man. It was not because he was long familiar with it. He was a newcomer in the land, and this was his first winter.

This quote in the beginning of the story reveals that the man is not a seasoned traveler in such cold conditions.  Instead of being afraid or careful of the vast isolation and extreme weather, he is not affected by it at all.  This not only foreshadows the man's tragic end, but enforces the theme that nature has dominion over man.  

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.

This quotation reveals that the man is able to understand concrete details and facts.  In this story he can recognize the cold, notice the location of the trees, follow the position of the sun, and find the area of most snow-covered streams.  Unfortunately, he cannot use all these concrete details to reach a higher understanding about his own faults as a human being and the power of unbridled nature.

Author's style:

The hair on the man’s face was similarly frosted, but more solidly. It took the form of ice and increased with every warm, moist breath from his mouth. Also, the man had tobacco in his mouth. The ice held his lips so tightly together that he could not empty the juice from his mouth. The result was a long piece of yellow ice hanging from his lips.

This passage contains one of the most memorable images from the work. The image of the ice freezing the man's lips together and the tobacco juice creating a type of icicle is beyond the physical experience of most readers. The quotation serves to show the reader just how frigid the area is.  In addition, the image shows the physical superiority of the ice as it seems to be literally encasing the man.

In a month no man had traveled up or down that silent creek. The man went steadily ahead. He was not much of a thinker

While this quotation reveals the man's lack of thought, it also presents a simple element of foreshadowing.  If nobody had traveled the area in a month, why should he think he can do it as a newcomer to the area?  The man will undoubtedly regret his decision.

Quotations about the old-timer from Sulphur Creek

Well, here he was; he had had the accident; he was alone; and he had saved himself. Those old men were rather womanish, he thought. All a man must do was to keep his head, and he was all right. Any man who was a man could travel alone.

That man from Sulphur Creek had spoken the truth when telling how cold it sometimes got in this country. And he had laughed at him at the time!

At first, the man feels superior to all of those who had warned him against traveling the Yukon Trail alone.  Not only does this quotation reveal the man's character flaws in general, but also his specific belief that he is somehow better than all the older, more-experienced travelers of the region.

Specifically, the old-timer from Sulphur Creek warns the man.  He represents wisdom and experience, which often goes unheeded by the younger people. As is usual in life, the man does not understand the truth until it is too late.
