John Locke

Any single man must judge for himself whether circumstances warrant obedience or resistance to the commands of the civil magistrate; we are all qualified, entitled, and morally obliged to evaluate the conduct of our rulers. This political judgment, moreover, is not simply or primarily a right, but like self-preservation, a duty to God. As such it is a judgment that men cannot part with according to the God of Nature. It is the first and foremost of our inalienable rights without which we can preserve no other.
