Without Freedom of thought there can be no such thing as wisdom;and no such thing as public liberty, without freedom of speech.

Without Freedom of Thought, there can be no such Thing as Wisdom; and no such Thing as publick Liberty, without Freedom of Speech; which is the Right of every Man, as far as by it, he does not hurt or controul the Right of another: And this is the only Check it ought to suffer, and the only Bounds it ought to know.

Freedom of thought ,…freedom of thought is essential to human progress. If we stop freedom of thought, we stop progress in our world. Because of this it is so important that we teach our children, our young people, the importance of freedom of thought. Freedom of thought begins with the right to ask questions. And this right our people in Burma have not had for so long that some of our young people do not quite know how to ask questions. One of the tasks we have set ourselves, in my party, the National League for Democracy is to teach our people to ask questions, not to accept everything that is done to them without asking why.

Intellectual freedom is essential to human society — freedom to obtain and distribute information, freedom for open-minded and unfearing debate, and freedom from pressure by officialdom and prejudices. Such a trinity of freedom of thought is the only guarantee against an infection of people by mass myths, which, in the hands of treacherous hypocrites and demagogues, can be transformed into bloody dictatorship. Freedom of thought is the only guarantee of the feasibility of a scientific democratic approach to politics, economy, and culture. But freedom of thought is under a triple threat in modern society—from the deliberate opium of mass culture, from cowardly, egotistic, and philistine ideologies, and from the ossified dogmatism of a bureaucratic oligarchy and its favorite weapon, ideological censorship. Therefore, freedom of thought requires the defense of all thinking and honest people.

Probably it is true enough that the great majority are rarely capable of thinking independently, that on most questions they accept views which they find ready-made, and that they will be equally content if born or coaxed into one set of beliefs or another. In any society freedom of thought will probably be of direct significance only for a small minority. But this does not mean that anyone is competent, or ought to have power, to select those to whom this freedom is to be reserved. It certainly does not justify the presumption of any group of people to claim the right to determine what people ought to think or believe.

Freedom of thought and of expression are not mere rights to be claimed. They have their roots deep in the existence of individuals as developing careers in time. Their denial and abrogation is an abdication of individuality and a virtual rejection of time as opportunity.

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living. It is clear also that thought is not free if all the arguments on one side of a controversy are perpetually presented as attractively as possible, while the arguments on the other side can only be discovered by diligent search.

In a free state there should be freedom of speech and thought.

Liberty is meaningless where the right to utter one's thoughts and opinions has ceased to exist. That, of all rights, is the dread of tyrants. It is the right which they first of all strike down. They know its power. Thrones, dominions, principalities, and powers, founded in injustice and wrong, are sure to tremble, if men are allowed to reason.

Freedom of speech implies the world isn’t defined. It is meaningful when people are allowed to see the world their way.

This in short is the case of the progressives who talk about freedom of thought. For them freedom of thought is synonymous to freedom of disowning one's God. This is, however, not freedom of thought but freedom of atheism.

Unless there is freedom of religion it is useless to speak of any other form of freedom.

"First Amendment freedoms are most in danger when the government seeks to control thought or to justify its laws for that impermissible end. The right to think is the beginning of freedom, and speech must be protected from the government because speech is the beginning of thought."

[Ashcroft v. Free Speech Coalition (00-795), 198 F.3d 1083, affirmed.]

Thinking is language spoken to oneself. Until language has made sense of an experience, that experience is meaningless.
