the humans around him as ancient men, wearing animal skins and living in caves or trees. In some of these visions, he is running alongside these men, protecting them from the terrors of the night. His relationship to Thornton, the novel implies, is like these ancient mandog connections。 it is primitive rather than civilized, and so it remains strong even as Buck leaves the civilized world behind. The qualities of Buck Experience is badly required in an unfamiliar and tough circumstance. Those who are experienced will always have the priority over the inexperienced. Buck’s experience is accumulated gradually after being sold to the north.
