The topic of this paper is Henry David Thoreau. Henry David Thoreau left us two most important options when things go very bad in this world: a bloodless but effective way of saying "no" and a fitting advice to rely on ourselves. He did this through his famous works, "Civil Disobedience" and "Walden." "Civil Disobedience" is about showing protest by resisting the orders of the authority being opposed. When authority conflicts with one's true values, the person has the right and duty to defend his or her conscience, and open rebellion does not have to be bloody.
