W: Hello, John, what’s up?
M: I have been working like hell with my mid-term paper.
W: Anything that I can help with? What is your topic?
M: The teacher asked us to pick one of the American writers in the period of realism and then make a brief introduction to him and then make a review of one work written by him.
W: Er...I bet the most famous writer of that period is Mark Twain who is called "the father of American literature. " What is your choice then?
M: Your idea occurred to me too, but T am afraid that my paper would turn out to he clich6 since many other students would work on him too.
W: Then whom did you pick?
M: Jack London. Do you think it is a good choice?
W: Definitely. Jack London was a prolific author. He was the pioneer in commercial magazine fiction, and he was one of the first fiction writers to obtain worldwide celebrity and a large fortune from his fiction alone.
M: I am fascinated by his novels which were set in the Klondike Gold Rush. I want to focus on his short story To Build a Fire.
W: That is a classical one. It is basically a story about an inexperienced adventurer and a canny dog.
M: Yes. I decided to write my review from a different angle though—basic instinct in mankind and animals.
W: That sounds innovative. And you can also quote naturalism as your supporting theory. You know the survival of the fittest, that sort of thing.
M: Good idea.
W: Naturalists see evolution as proof that the world is deterministic and that humans do not have free will. Since the evolutionary world is based on a series of links, any action humans make is not "the first step. " Rather, the action has been caused by prior environmental, social, and biological factors beyond our individual control.
M: Determinism influences naturalists a lot. After all, the environment, and not the human, has determined these actions. Therefore keen instinct rather than civilized intellect is necessary for survival. Just like the hero in To Build a Fire, he is lacking this instinct.
W: You are right.
