"Men feared witches and burnt women. It is the function of speech to free men from the bondage of irrational fears."

"Those who won our independence by revolution were not cowards. They did not fear political change. They did not exalt order at the cost of liberty."

"We can have a democratic society or we can have great concentrated wealth in the hands of a few. We cannot have both."

"Those who won our independence believed that the final end of the state was to make men free to develop their faculties, and that in its government the deliberative forces should prevail over the arbitrary. They valued liberty both as an end and as a means. They believed liberty to be the secret of happiness and courage to be the secret of liberty. They believed that freedom to think as you will and to speak as you think are means indispensable to the discovery and spread of political truth; that without free speech and assembly discussion would be futile; that with them, discussion affords ordinarily adequate protection against the dissemination of noxious doctrine; that the greatest menace to freedom is an inert people; that public discussion is a political duty; and that this should be a fundamental principle of the American government."

"Full and free exercise of this right by the citizen is ordinarily also his duty; for its exercise is more important to the nation than it is to himself. Like the course of the heavenly bodies, harmony in national life is a resultant of the struggle between contending forces. In frank expression of conflicting opinion lies the greatest promise of wisdom in governmental action; and in suppression lies ordinarily the greatest peril."
