"To Build a Fire" is one of the greatest short stories ever and perhaps Jack London's masterpiece. A consummate naturalist work, it is a superb example of realism, almost painstakingly portraying what it is like to be in the bitterly cold Yukon without adequate provisions. This alone would lend significant historical value, an intriguing look at America's last frontier, but the story is of course far more than this. Its genius is its simplicity; London manages to put a world of significance into a short work with very little conventional action. The story itself is absorbing; suspense mounts and mounts, and London has the trick of making us always feel that something ultra exciting is happening or about to happen. His prose is also top-notch - restrained yet lyrical. What makes the story great above all, though, is its plethora of important themes: human hubris, nature's immensity, humanity vs. nature, etc. Naturalism normally shows how environment shapes people, sometimes almost fatalistically, but London vividly shows that we are always in control of our fate. Nature may seem unsympathetic or unforgiving but is actually neutral and certainly not malicious; it is a blank canvas on which we paint our lives - sometimes to our detriment. One could argue that the story's real message boils down to the famous Boy Scout motto: "Be Prepared." It unforgettably shows how this is far easier said than done. An excellent work all around, "To Build" is essential for anyone interested in London, American literature, or the time and place - nay, for anyone at all interested in short stories. It is worth reading alone, but the fact that it is in virtually every London collection plus many others makes a standalone hard to justify. The important thing at any rate is to read it in some form.
