Over time I've managed to winnow down my nominees for "most common literary themes" to the following. I realize that this isn't an inclusive list, but it incorporates (I believe) the most prevalent themes in classic and popular literature.
- GOOD VS. EVIL
- AKA: Courage, Duty, Loyalty, Patriotism, Heroism, Nobility/Honor, Crime Does Not Pay
- EXPLANATION: Most stories exploring this theme feature good triumphing over evil, and all the better if "good" is is vastly outmatched by "evil" but triumphs anyway, a la David and Goliath, The Lord of the Rings, or Harry Potter; though, sometimes, evil ends up triumphing over good (Night).
- OVERLAP: This category often overlaps with Love and Friendship (since the heroes risk their lives to preserve those they love), Man vs. Himself (since the heroes often struggle with themselves to find the courage to go on), Fate vs. Free Will (since often there is a prophecy or some other supernatural agency that has thrust heroism upon them), and Suffering and Redemption (since they often have to overcome their own demons in order to prevail).
- OTHER EXAMPLES: The Iliad, Homer; Le Morte d'Arthur, Malory; Ivanhoe, Scott; The Three Muskateers, Dumas; Treasure Island, Stevenson; The Red Badge of Courage, Crane; The Lord of the Rings, Tolkein; all stories with detectives or superheroes
- MAN VS. NATURE
- AKA: Survival, Quest for Immortality
- EXPLANATION: Includes all stories in which the main character finds himself pitted against weather/environment (To Build a Fire), animals (Moby Dick), or life/death (Frankenstein). Sometimes humans triumph over nature (Swiss Family Robinson); more commonly, nature triumphs over humans (Jurassic Park). Rarely, man and nature learn to exist together in harmony (Jungle Book); more often, mankind risks destroying nature and themselves with untamed technology (most science fiction).
- OTHER EXAMPLES: The Old Man and the Sea, Hemingway; Call of the Wild, London; Robinson Crusoe, Defoe; The Picture of Dorian Grey, Wilde; Flowers for Algernon, Keyes
- LOVE AND FRIENDSHIP
- AKA: Sacrifice, Love, Duty
- EXPLANATION: Includes pretty much all stories about love, in all its forms: romantic, platonic, godly, unrequited, familial, altruistic. Usually, love triumphs over the barriers (natural, societal) placed in its way (Pride and Prejudice, Jane Eyre) though, sometimes, love is unable to overmaster the odds set against it (The Hunchback of Notre Dame, Romeo and Juliet, Ethan Frome). The one thing they almost all have in common is the overarching message that a life lived without love is a life half-lived.
- OVERLAP: Stories about obsessive love/jealousy (ex: Wuthering Heights) or improper love/jealousy (Sons and Lovers, Lolita) more properly belong under Man vs. Himself
- OTHER EXAMPLES: Little Women, Alcott; The Velveteen Rabbit, Bianco, Of Mice and Men, Steinbeck; The Giving Tree, Silverstein
- MAN VS. SOCIETY
- AKA: Freedom vs. Authority, Individuality, Justice, Social Justice
- EXPLANATION: My entirely unscientific survey of literature suggests that there are, alas, more examples of society conquering man (Catch 22, Farenheit 451, 1984) than examples of man conquering society (Moll Flanders, Tom Sawyer); though sometimes these two forces end in an uneasy draw (To Kill a Mockingbird). A common subtext is that even society seems to triumph, the human spirit remains unconquered (Scarlett Letter, Uncle Tom's Cabin; Les Miserables).
- OTHER EXAMPLES: Huckleberry Finn, Twain; Tale of Two Cities, Dickens, Cry, the Beloved Country, Paton; Heart of Darkness, Conrad; Invisible Man, Ellison; Native Son, Wright; Diary of Anne Frank, Frank; Animal Farm, Orwell; Grapes of Wrath, Steinbeck; The Hunchback of Notre Dame, Hugo
- MAN VS. HIMSELF
- AKA: Obsession, Greed, Pride, Hubris, Corruption
- EXPLANATION: The usual subtext of these stories is that man carries within him the seeds of his own destruction, and the causes of self-destruction are indeed myriad: pride/vanity/selfishness (Hector in The Iliad, Rebecca Sharp in Vanity Fair), greed/ambition (Dr. Faustus, Richard III, Macbeth), obsession (Moby Dick), insanity (The Telltale Heart), desire for revenge (Othello, Count of Monte Cristo), jealousy (Wuthering Heights), cruelty (The Lord of the Flies), etc. Sometimes, however, "Man vs. Himself" shows up as "You should never give up on your dream, no matter how hard the struggle," a particularly popular theme in teen fiction and movies about sports.
- OVERLAP: Stories about the ability of power/money to corrupt the human spirit overlap with Man vs. Society; though allowing themselves to be corrupted is a human failing, the instigating event is often a social inequality (political corruption, as in All the King's Men)
- OTHER EXAMPLES: The Great Gatsby, Fitzgerald; Frankenstein, Shelley; Dr. Jekyll and Mr. Hyde, Stevenson; Pride & Prejudice, Austen
- FATE/FAITH/PREDESTINATION VS. FREE WILL.
- AKA: Truth, Faith, Fate.
- EXPLANATION: These books explore whether man has the power to create his destiny, or whether his destiny is predetermined, whether by willful gods or fickle fate. This theme is more common in pre-20th century literature, when believe was more widespread that the gods meddled in the everyday lives of men. However, the theme lives in on literature by worth authors (think magical realism) and in novels that feature reluctant heroes who are somehow "chosen" or "predestined" to save the world.
- OTHER EXAMPLES: Iliad, Homer; Oedipus Rex, Sophocles; Harry Potter, Rowlings; The Lord of the Rings, Tolkein.
- SUFFERING AND REDEMPTION
- AKA: Triumph over Adversity, Self-Reliance, Perseverance
- EXPLANATION: These stories typically feature characters who seek to overcome obstacles or redeem past mistakes through courage, sacrifice, remorse, or divine intervention. Sometimes they succeed (A Christmas Carol, Dickens); sometimes, however, one lapse in judgment haunts them forever (Lord Jim, Conrad; Atonement, McEwan)
- OTHER EXAMPLES: Jane Eyre, Bronte, Crime and Punishment, Dostoevsky; Scarlet Letter, Hawthorne; David Copperfield, Dickens; Les Miserables, Hugo; A Tree Grows in Brooklyn, Smith
