Jack London’s Autobiographical Themes

Many of Jack London’s books are loosely autobiographical, so his own story is a major theme in his work. In fact, he said as much in a letter to a friend:

No; I’m damned if my stories just come to me. I had to work like the devil for the themes. Then, of course, it was easy to just write them down. Expression, you see - with me - is far easier than invention.

Stick to the Northland

If many of Jack London’s novels have one theme in common, it’s the Northland. Because he knew it well, it was one of his favorite settings. In discussing the themes of his work in the letter quoted above, London wrote, “I shall have to stick to the Northland for some time yet.”

Jack London was born in 1876 and began life as a sailor at the tender age of fourteen. He traveled to Siberia, Alaska, and Yukon Territory, among other places. He spent a winter surviving in a primitive cabin in the Klondike and nearly died of scurvy. These northern adventures figure heavily into the autobiographical themes in his books.

  • The Road (1907)

Other Basic Themes in Jack London's Novels

While part of what Jack London's novels are based upon is his life, there are also some themes that could arguably form the basis of many of London's works. These include evolution, socialism, animal activism, and a return to the land.

Animal Activism

Jack London was committed to fighting animal cruelty and was an activist during his lifetime. You can see themes of animal activism and animal cruelty within many of his stories and novels:

  • In White Fang, the title character must engage in forced dog fights, and the vivid storytelling reveals the cruelty of this practice.
  • In The Call of the Wild, the main character, Buck, must endure near starvation and cramped quarters in a shipping crate. Another dog is heartlessly killed because he can no longer perform his duty.
  • In Jerry of the Islands, a terrier is chosen as a sacrifice and endures other hardships.

Evolution and Survival of the Fittest

A serious believer and scholar of Charles Darwin's theories of evolution, London considered survival of the fittest to be at the core of everything he wrote about - and, indeed, at the core of most situations in life. You can see this theme in much of his writing, including the following:

  • In The Call of the Wild, London writes about Buck, who must embrace his wild nature to survive. Other characters who refuse to become wild are killed.
  • In White Fang, the title character must endure many hardships that would have killed a weaker dog or wolf. His survival is the heart of the story.
  • In The Sea-Wolf, London directly refers to the theories of Darwin and uses this as a basis for a character who survives against all odds.

Socialism

Jack London was also a political philosopher and had a deep passion for social theories that shaped the way that people lived in conjunction with one another, removing them further and further from a natural state of being. London believed in the theories of Karl Marx, and this can be seen in some of his earlier writings in a subtle way. In some of his novels, Jack London explores the theme of socialism in detail:

  • In Martin Eden, the main character is an individualist, but embracing this philosophy instead of socialism leads to his demise.
  • The Iron Heel explores a fictional future in which socialism has a prominent place in American politics.
  • In The Sea-Wolf, London specifically mentions Nietzsche, and the story may be a rebuttal to the idea of the “superman” proposed by Nietzsche and the ideals of individualism.

Return to the Land

Perhaps, the most pervasive theme in Jack London’s novels was the ideas of returning to the land. London believed in a return to the land as the solution of many of society’s problems. The central conflict of man against the surrounding environment was, to him, the essence of existence, and he had strong beliefs against any societal organization that took humans further away from that by interfering with the natural pace of their lives.

This can be seen again and again in all of his novels, each of which, in its own way, tells the story of a person - or animal - returning to his roots within the natural earth in order to restore sense and rhythm to life.
