Henry David Thoreau lived during the mid-1800s, but the questions he explored in his writing — such as how to live deliberately, what it means to act with conscience, and what we owe to the natural world — have never felt more urgent. Here is an introduction to five of his most famous works, with curricular connections, discussion prompts, and related classroom resources for each. After reading, you can take the learning one step further and explore the Henry David Thoreau classroom collection, created in consultation with The Walden Woods Project, on PBS LearningMedia. 

Walden: Or, Life in the Woods (1854)

Thoreau lived in Concord, Massachusetts, during the American Industrial Revolution: a time when people were leaving farms to work in factories, cities were growing, and the pressure to earn and consume was becoming a defining fixture of everyday life for the first time. He observed his neighbors caught in a cycle of work and stress that they had not consciously chosen — what he famously called "quiet desperation."

In the summer of 1845, Thoreau began an experiment designed to answer the question: What does it actually mean to live well? He walked into the woods outside Concord, built a 10-by-15-foot house next to Walden Pond with his own hands, and lived there for two years, two months, and two days. 

He stripped his life down to its most basic material needs and spent his days walking through the woods, recording everything he heard and saw with scientific precision. His journals were so careful and sustained that scientists have recently used them to track changes to Massachusetts' climate over time. Thoreau eventually found that this same close attention, with practice, could be turned inward, toward his own sense of what a good life required. He spent the next seven years editing those journals into Walden, now considered one of the most influential books in American history and literature. 

Discussion Starter: 

Thoreau conducted an experiment to live simply and deliberately. As part of this experiment, he built a house for only $28.12. He recorded every expense in his journal, down to the cost of nails and hinges. Ask your students: Thoreau chose to spend as little money as possible at a time when the pressure to earn and consume was growing quickly. Can choosing to live simply be a form of protest? What might this look like today? 

Key Quotations From Walden:

“I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.”

• Use for close reading or as a personal essay prompt. Ask students: What does it mean to live deliberately? 

“Simplicity, simplicity, simplicity! I say, let your affairs be as two or three, and not a hundred or a thousand.”

• Use as a discussion starter or journal prompt about setting priorities. Ask students: What are your most important priorities? What do you think you could simplify to focus on them?

“Civil Disobedience” (1849)

In the summer of 1846, one year into his experiment at Walden Pond, Thoreau walked into Concord and was stopped by the local tax collector, who told him he owed nearly six years of unpaid poll taxes. Thoreau refused to pay. He believed that by paying taxes, he was supporting an economy tied to slavery and funding the Mexican-American War, which he saw as a campaign to expand enslavement in the West. Thoreau was arrested and spent the night in jail. Someone, likely his aunt, paid the tax without his knowledge the next morning. Thoreau was furious.  

The experience highlighted one of the major questions Thoreau worked through during his lifetime: How can you live with a clear conscience when simply going about your day makes you part of something you find morally wrong? He published “Civil Disobedience” in 1849. The essay argues that people have a moral obligation to refuse to follow unjust laws, an approach that Thoreau himself tried to implement in his own life. He and his family were active in Concord’s abolitionist movement and participated in the Underground Railroad. The essay has been remarkably influential — Mahatma Gandhi, Malcolm X, and Martin Luther King Jr. all read “Civil Disobedience” and drew on it to build their own civil rights movements. 

Discussion Starter: 

Thoreau’s essay was originally titled “Resistance to Civil Government.” It was republished as “Civil Disobedience” after his death. Ask your students: Thoreau didn’t choose the title “Civil Disobedience.” How does a title change the way we understand a text? Does it matter who chooses it?

Key Quotations From “Civil Disobedience”:

“Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn.”

• Use for a close reading or as a discussion prompt. Ask students: What does “counter-friction” mean? Can you think of modern examples of people acting as a counter-friction?

“Under a government which imprisons any unjustly, the true place for a just man is also a prison.”

• Use as the topic for a debate or as a journal or discussion prompt. Ask students: Do you agree with Thoreau? Why or why not?

A Week on the Concord and Merrimack Rivers (1849)

In the late summer of 1839, Thoreau and his brother John built a boat and set off on a two-week river adventure. They called their boat “Musketaquid,” after the name Indigenous people gave to the river lowlands. The brothers boated down the Concord River and up the Merrimack into New Hampshire, where they continued their adventure on foot, into the White Mountains. Along the way, they watched the New England landscape they loved being reshaped by mills, dams, and factory towns. 

More than anything else, the trip was an adventure shared by brothers. Growing up, Henry and John were inseparable, spending most of their time exploring the woods and rivers around Concord together. When John died suddenly of tetanus, or lockjaw, three years after their river trip, Thoreau was devastated. He spent years turning his journal entries from those two weeks into A Week on the Concord and Merrimack Rivers, equally a travel narrative and a tribute to his brother, drawing on Hindu texts, Greek philosophy, and ancient literature. 

Discussion Starter:

A Boston publisher agreed to print 1,000 copies of the book, but only if Thoreau would buy back any that didn’t sell. Thoreau eventually had to buy back 706 of them, which cost him $300 — an entire year’s income for the average American at the time. He stored them all in the family home’s attic. Ask your students: Thoreau published a book that almost nobody bought. Does commercial success determine the value of a literary work? What other measures might be used to assess the value of art?

Key Quotations From A Week on the Concord and Merrimack Rivers:

“The world is but a canvas to our imaginations.”

• Use as a discussion or creative writing prompt. Ask your students: What does this say about the relationship between imagination and life? How do you think this philosophy may have shaped how Thoreau lived and wrote? 

“The language of Friendship is not words, but meanings. It is an intelligence above language.”

• Use as a creative writing or journal prompt. Have students write about an important friendship or relationship in their lives, focusing on the idea of communicating without words.

“Walking”(1862)

In 1851, Thoreau gave a speech at the Concord Lyceum that would be published as “Walking” in 1862, two months after his death. He called it an introduction to “all I may write hereafter,” signaling how central these ideas were to everything he believed. In the text, Thoreau notes that he spent four hours a day walking and saw this as essential to preserving his health and spirits.

The essay carries more weight than its title might suggest. Thoreau wrote it at a time when Americans were sharply divided over the institution of slavery. In that context, “Walking’s” argument that the freedom to roam in nature is a universal human right held a deeper meaning. Thoreau did his best thinking while walking in nature, and he believed every person deserved that same access. 

For Thoreau, protecting human freedom and protecting the natural world were both part of the same idea. The essay is now considered a landmark of the modern environmental movement, as it was one of the first works to argue that the wilderness should be protected as something essential to being human. 

Discussion Starter:

The essay’s most famous line, “In Wildness is the preservation of the world,” 

is often misquoted as “In Wilderness.” The distinction is important because while wilderness is a place that can be visited, wildness is a state of being that everyone should be able to access — like freedom. Ask your students: What is the difference between “wildness” and “wilderness”? Why would the distinction be important to Thoreau, based on your understanding of this text?

Key Quotations From “Walking”:

“I wish to speak a word for Nature, for absolute Freedom and Wildness, as contrasted with a freedom and culture merely civil, — to regard man as an inhabitant, or part and parcel of Nature, rather than a member of society.”

• Use for close reading or a journal prompt. Ask your students: How is the freedom that Thoreau is arguing for different from a “freedom and culture merely civil”?

“I am alarmed when it happens that I have walked a mile into the woods bodily, without getting there in spirit.” 

• Use as a journal or discussion prompt. Ask your students about a time they have been somewhere physically, but not mentally. How did that feel?

“Slavery in Massachusetts”(1854)

In May 1854, a formerly enslaved man named Anthony Burns was arrested in Boston and ordered to be returned to slavery in Virginia under the Fugitive Slave Act. The law required citizens in free states to assist in capturing escaped enslaved people and returning them to their owners, which meant that Northerners were required by law to participate in slavery. That same month, Congress passed the Kansas-Nebraska Act, allowing western states to decide for themselves whether to permit slavery. 

Thoreau responded. On July 4, 1854, he delivered “Slavery in Massachusetts” at a protest rally in Framingham, Massachusetts, speaking alongside fellow abolitionists William Lloyd Garrison, Wendell Phillips, and Sojourner Truth. Massachusetts was as much a target as the South, and Thoreau directed his anger at the judges, politicians, and ordinary citizens enforcing the Fugitive Slave Act. The speech was one of the most direct and scathing pieces of political writing Thoreau ever produced, and it stands as a model of how to speak honestly about injustice. 

Discussion Starter:

“Slavery in Massachusetts”was one of the few works by Thoreau that was widely read and discussed the moment it appeared. Unlike Walden and A Week on the Concord and Merrimack Rivers, which sold poorly at first, the speech resonated immediately. Ask students: Why do you think this piece of writing immediately resonated with audiences, while most of Thoreau’s other writings did not? What does this tell us about the moment the speech was published and shared?

Key Quotations From “Slavery in Massachusetts”:

“I feel that my investment in life here is worth many percent less since Massachusetts last deliberately sent back an innocent man, Anthony Burns, to slavery... Man's influence and authority were on the side of the slaveholder, and not of the slave — of the guilty, and not of the innocent — of injustice, and not of justice.”

• Use for close reading. Ask students: How does Thoreau use parallel structures to make his argument more effective? 

“Three years ago, also, just a week after the authorities of Boston assembled to carry back a perfectly innocent man, and one whom they knew to be innocent, into slavery, the inhabitants of Concord caused the bells to be rung and the cannons to be fired, to celebrate their liberty... As if those three millions had fought for the right to be free themselves, but to hold in slavery three million others. Nowadays, men wear a fool's-cap, and call it a liberty-cap.”

• Use as a discussion or journal prompt. Ask students: What does Thoreau mean when he says “Nowadays, men wear a fool's-cap, and call it a liberty-cap”? Can you think of a modern example where the same statement could apply?

_________________________________________________________________________________

Thoreau lived in a politically divided world being reshaped by industry and moving faster than most people could keep up with. He was writing for anyone who suspected, on some level, that the life they were living wasn’t quite the life they were meant to experience. He was writing for his time and also, somehow, for ours.
