Themes are the fundamental and often universal ideas explored in a literary work.

The Importance of Love and Compassion

In Les Misérables, Hugo asserts that love and compassion are the most important gifts one person can give another and that always displaying these qualities should be the most important goal in life. Valjean’s transformation from a hate-filled and hardened criminal into a well-respected philanthropist epitomizes Hugo’s emphasis on love, for it is only by learning to love others that Valjean is able to improve himself. While Valjean’s efforts on behalf of others inevitably cause him problems, they also give him a sense of happiness and fulfillment that he has never before felt. Valjean’s love for others—in particular, for Cosette—is what keeps him going in desperate times.

Hugo also makes clear that loving others, while difficult, is not always a thankless task, and he uses Valjean and Fauchelevent to show that love begets love, and compassion begets compassion. Valjean jumps out of a crowd of onlookers to rescue Fauchelevent; years later, Fauchelevent repays Valjean’s bravery by offering him refuge in the convent of Petit-Picpus. In Hugo’s novel, love and compassion are nearly infectious, passed on from one person to another. After M. Myriel transforms Valjean with acts of trust and affection, Valjean, in turn, is able to impart this compassion to Cosette, rescuing her from the corrupting cruelty of the Thénardiers. Cosette’s love then reaches fulfillment through her marriage to Marius, and their love for each other leads them both to forgive Valjean for his criminal past.

Social Injustice in Nineteenth-Century France

Hugo uses his novel to condemn the unjust class-based structure of nineteenth-century France, showing time and again that the society’s structure turns good, innocent people into beggars and criminals. Hugo focuses on three areas that particularly need reform: education, criminal justice, and the treatment of women. He conveys much of his message through the character of Fantine, a symbol for the many good but impoverished women driven to despair and death by a cruel society. After Fantine is abandoned by her aristocratic lover, Tholomyès, her reputation is indelibly soiled by the fact that she has an illegitimate child. Her efforts to hide this fact are ruined by her lack of education—the scribe to whom Fantine dictates her letters reveals her secret to the whole town. Ironically, it is not until the factory fires Fantine for immorality that she resorts to prostitution. In the character of Fantine, Hugo demonstrates the hypocrisy of a society that fails to educate girls and ostracizes women such as Fantine while encouraging the behavior of men such as Tholomyès .

Hugo casts an even more critical eye on law enforcement. The character of Valjean reveals how the French criminal-justice system transforms a simple bread thief into a career criminal. The only effect of Valjean’s nineteen years of mistreatment on the chain gang is that he becomes sneaky and vicious—a sharp contrast to the effect of Myriel’s kindness, which sets Valjean on the right path almost overnight. Another contrast to Valjean’s plight is the selective manner in which the Parisian police deal with the Patron-Minette crime ring. Unlike Valjean, Patron-Minette and their associates are real criminals who rob and murder on a grand scale, but they receive only short sentences in prisons that are easy to escape. In the French society of Les Misérables, therefore, justice is clumsy at best. It barely punishes the worst criminals but tears apart the lives of people who commit petty crimes.

The Long-Term Effects of the French Revolution on French Society

In Les Misérables, Hugo traces the social impact of the numerous revolutions, insurrections, and executions that took place in late eighteenth- and early nineteenth-century France. By chronicling the rise and fall of Napoléon as well as the restoration and subsequent decline of the Bourbon monarchy, Hugo gives us a sense of the perpetual uncertainty that political events imposed upon daily life. Though Hugo’s sympathies are with republican movements rather than with the monarchy, he criticizes all of the regimes since the French Revolution of 1789 for their inability to deal effectively with social injustice or eliminate France’s rigid class system. Hugo describes the Battle of Waterloo, for instance, in glowing terms, but reminds us that at the end of the glorious battle, the old blights of society, like the grave robbers, still remain. Similarly, the battle at the barricade is both heroic and futile—a few soldiers are killed, but the insurgents are slaughtered without achieving anything. The revolution that Hugo champions is a moral one, in which the old system of greed and corruption is replaced by one of compassion. Although both Napoléon and the students at the barricade come closer to espousing these values than the French monarchs do, these are not values than can be imposed through violence. Indeed, Hugo shows that Napoléon and the students at the barricades topple as easily as the monarchy.
