Thoreau distinguishes between obeying the law and acting according to moral judgement. He argues that legality alone does not make an action right, and that citizens should not treat obedience to government as their highest duty. Instead, individuals must consider whether their conduct is consistent with what they understand to be just.

Within Resistance to Civil Government, this principle underpins Thoreau’s defence of civil disobedience. His argument does not suggest that every personal preference should override the law. Rather, it places responsibility on individuals to examine whether laws or state policies require them to participate in injustice. For Thoreau, conscience therefore imposes an obligation that can, in serious cases, take precedence over legal compliance. The passage captures a central tension in political ethics: whether citizens should obey established law when their considered moral judgement tells them that the law is wrong.
