On the Duty of Civil Disobedience

Henry David Thoreau's On the Duty of Civil Disobedience argues that conscience cannot be handed over to government simply because law carries official force. Individuals become agents of injustice when obedience enables policies they know to be wrong. Thoreau developed the essay from lectures on the rights and duties of the individual in relation to the state, with slavery and the Mexican-American War shaping its urgency.

His central image treats government as a machine. If that machine produces injustice, a conscientious citizen should become "counter friction" capable of stopping its operation. Resistance is therefore more demanding than private disagreement: a person must avoid lending money, labor, legitimacy, or compliance to the wrong being opposed.

The essay does not present passivity as its goal. Thoreau distinguishes his position from contemporary nonresistance and asks for better government even as he imagines a society prepared for far less coercive rule. The word "civil" concerns the citizen's relation to the state, not mere politeness. Readers interested in political philosophy, abolitionism, protest, and ethical responsibility can use the work to examine when legality and justice diverge, and what personal cost a refusal to cooperate may require.
