Since the earliest days, philosophers have dreamed of a country where the mind and spirit of man would be free; where there would be no limits to inquiry; where men would be free to explore the unknown and to challenge the most deeply rooted beliefs and principles. Our First Amendment was a bold effort to adopt this principle — to establish a country with no legal restrictions of any kind upon the subjects people could investigate, discuss, and deny.

If I valued fame, I should flatter received opinions, which have gathered strength by time, and will yet wear longer than any living works to the contrary. But, for the soul of me, I cannot and will not give the lie to my own thoughts and doubts, come what may. If I am fool, it is, at least, a doubting one; and I envy no one the certainty of his self-approved wisdom.
Our Constitution relies on our electorate’s complete ideological freedom to nourish independent and responsible intelligence and preserve our democracy from that submissiveness, timidity and herd-mindedness of the masses which would foster a tyranny of mediocrity.

We cannot have a society half slave and half free; nor can we have thought half slave and half free. If we create an atmosphere in which men fear to think independently, inquire fearlessly, express themselves freely, we will in the end create the kind of society in which men no longer care to think independently or to inquire fearlessly.

People say we ought not to allow ourselves to be drawn into a theoretical antagonism between Nazidom and democracy; but the antagonism is here now. It is this very conflict of spiritual and moral ideas which gives the free countries a great part of their strength. You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police. On all sides they are guarded by masses of armed men, cannons, aeroplanes, fortifications, and the like — they boast and vaunt themselves before the world, yet in their hearts there is unspoken fear. They are afraid of words and thoughts; words spoken abroad, thoughts stirring at home — all the more powerful because forbidden — terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic. They make frantic efforts to bar our thoughts and words; they are afraid of the workings of the human mind. Cannons, airplanes, they can manufacture in large quantities; but how are they to quell the natural promptings of human nature, which after all these centuries of trial and progress has inherited a whole armoury of potent and indestructible knowledge?

The time to assert rights is when they are denied; the men to assert them are those to whom they are denied. The community which dares not protect its humblest and most hated member in the free utterance of his opinions, no matter how false or hateful, is only a gang of slaves.

As reported in the Liberator (21 Dec 1860).
Note: There is a synthetic quotation frequently attributed to Phillips that is a actually combination of this one, and these three others:
No matter whose lips that would speak, they must be free and ungagged. The community which dares not protect its humblest and most hated member in the free utterance of his opinions, no matter how false or hateful, is only a gang of slaves. If there is anything in the universe that can’t stand discussion, let it crack.
While Phillips often reused rhetorical elements (as most orators do), this particular combination appears to be combination not actually found in his speeches or writing.
“The right to think, to know and to utter,” as John Milton said, is the dearest of all liberties. Without this right, there can be no liberty to any people; with it, there can be no slavery.

Errors and mistakes, however gross, in matters of opinion, if they are sincere, are to be pitied, but not punished nor laughed at. The blindness of the understanding is as much to be pitied as the blindness of the eye, and there is neither jest nor guilt in a man’s losing his way in either case. Charity bids us set him right if we can, by arguments and persuasions; but charity, at the same time, forbids, either to punish or ridicule his misfortune.

Every man’s reason is, and must be, his guide; and I may as well expect that every man should be of my size and complexion, as that he should reason just as I do. Every man seeks for truth; but God only knows who has found it. It is, therefore, as unjust to persecute as it is absurd to ridicule people for those several opinions which they cannot help entertaining upon the conviction of their reason.

What an effort, my dear Sir, of bigotry in Politics & Religion have we gone through. The barbarians really flattered themselves they should even be able to bring back the times of Vandalism, when ignorance put every thing into the hands of power & priestcraft. All advances in science were proscribed as innovations. They pretended to praise & encourage education, but it was to be vain the education of our ancestors. We were to look backwards not forwards for improvement, the President himself declaring in one of his answers to addresses that we were never to expect to go beyond them in real science. This was the real ground of all the attacks on you: those who live by mystery & charlatanerie, fearing you would render them useless by simplifying the Christian philosophy, the most sublime & benevolent, but most perverted system that ever shone on man, endeavored to crush your well earnt, & well deserved fame.

Well aware that the opinions and belief of men depend not on their own will, but follow involuntarily the evidence proposed to their minds; that Almighty God hath created the mind free, and manifested his supreme will that free it shall remain by making it altogether insusceptible of restraint; that all attempts to influence it by temporal punishments, or burthens, or by civil incapacitations, tend only to beget habits of hypocrisy and meanness, and are a departure from the plan of the holy author of our religion, who being lord both of body and mind, yet chose not to propagate it by coercions on either, as was in his Almighty power to do, but to extend it by its influence on reason alone; that the impious presumption of legislators and rulers, civil as well as ecclesiastical, who, being themselves but fallible and uninspired men, have assumed dominion over the faith of others, setting up their own opinions and modes of thinking as the only true and infallible, and as such endeavoring to impose them on others, hath established and maintained false religions over the greatest part of the world and through all time ….

- the phrase "but to extend it by its influence on reason alone" was struck.
Gentlemen, you can never make me believe — no statute can ever convince me, that there is any infinite Being in this universe who hates an honest man. It is impossible to satisfy me that there is any God, or can be any God, who holds in abhorrence a soul that has the courage to express his thought. Neither can the whole world convince me that any man should be punished, either in this world or in the next, for being candid with his fellow-men. If you send men to the penitentiary for speaking their thoughts, for endeavoring to enlighten their fellows, then the penitentiary will become a place of honor, and the victim will step from it — not stained, not disgraced, but clad in robes of glory.

Progress generally begins in skepticism about accepted truths. Intellectual freedom means the right to reexamine much that has been long taken for granted. A free man must be a reasoning man, and he must dare to doubt what a legislative or electoral majority may most passionately assert. The danger that citizens will think wrongly is serious, but less dangerous than atrophy from not thinking at all.

Our forefathers found the evils of free thinking more to be endured than the evils of inquest or suppression. They gave the status of almost absolute individual rights to the outward means of expressing belief. I cannot believe that they left open a way for legislation to embarrass or impede the mere intellectual processes by which those expressions of belief are examined and formulated. This is not only because individual thinking presents no danger to society, but because thoughtful, bold and independent minds are essential to wise and considered self-government.

The notion of a Christian commonwealth should be exploded forever. … Government should protect every man in thinking and speaking freely, and see that one does not abuse another.

No government has the right to decide on the truth of scientific principles, nor to prescribe in any way the character of the questions investigated. Neither may a government determine the aesthetic value of artistic creations, nor limit the forms of literacy or artistic expression.

I believe that that community is already in process of dissolution where each man begins to eye his neighbor as a possible enemy, where non-conformity with the accepted creed, political as well as religious, is a mark of disaffection; where denunciation, without specification or backing, takes the place of evidence; where orthodoxy chokes freedom of dissent; where faith in the eventual supremacy of reason has become so timid that we are not enter our convictions into the open list, to win or lose. Such fears as these are a solvent which can eat out the cement that binds the stones together; they may in the end subject us to a despotism as evil as any that we dread; and they can be allayed only in so far as we refuse to proceed on suspicion, and trust one another until we have tangible ground for misgiving,

The last lesson a man ever learns is, that liberty of thought and speech is the right for all mankind; that the man who denies every article of our creed is to be allowed to preach just as often and just as loud as we ourselves. We have learned this, — been taught it by persecution on the question of slavery. No matter whose lips that would speak, they must be free and ungagged.

At Cambridge University I was taught a laudable method of argument: you never personalise, but you have absolutely no respect for people’s opinions. You are never rude to the person, but you can be savagely rude about what the person thinks. That seems to me a crucial distinction: people must be protected from discrimination by virtue of their race, but you cannot ring-fence their ideas. The moment you say that any idea system is sacred, whether it’s a religious belief system or a secular ideology, the moment you declare a set of ideas to be immune from criticism, satire, derision, or contempt, freedom of thought becomes impossible.

I am really mortified to be told that, in the United States of America, a fact like this can become a subject of enquiry, and of criminal enquiry too, as an offence against religion: that a question about the sale of a book can be carried before the civil magistrate. Is this then our freedom of religion? And are we to have a Censor whose imprimatur shall say what books may be sold, and what we may buy? And who is thus to dogmatise religious opinions for our citizens? Whose foot is to be the measure to which ours are all to be cut or stretched? Is a Priest to be our Inquisitor, or shall a layman, simple as ourselves, set up his reason as the rule for what we are to read, & what we must believe? It is an insult to our citizens to question whether they are rational beings or not; and blasphemy against religion to suppose it cannot stand the test of truth and reason.
