Which book by Henry David Thoreau is regarded as a philosophical treatise on living simply and in harmony with nature?

• A. The Maine Woods
• B. A Week on the Concord and Merrimack Rivers
• C. Walden
• D. Civil Disobedience

Answer: (C)

Living simply and in harmony with nature is explored in Walden, where Thoreau details his two-year experiment living in a cabin near Walden Pond. The work presents reflections on why people accumulate possessions and how a life of deliberate simplicity, self-reliance, and closeness to the natural world can bring clarity and integrity. It’s written as meditations and observations rather than a travelogue or a political tract, which is why it’s considered a philosophical treatise.

The Maine Woods focuses on wilderness travel and natural history observations, not on a sustained philosophical argument about living well. A Week on the Concord and Merrimack Rivers blends literary reflection with travel narrative and personal musings, rather than presenting a concise philosophical case. Civil Disobedience is a political essay advocating individual conscience and resistance to unjust government actions, distinct from a broad meditation on living with nature.
