Dissident ideas can still exist in such a situation, but they will be drowned in criticism and made disreputable, because they are outside the acceptable choices. Or they may be allowed to survive in the corners of the culture emaciated, but alive-and presented as evidence of our democracy, our tolerance, and our pluralism.

To view the opposition as dangerous is to misunderstand the basic concepts of democracy. To oppress the opposition is to assault the very foundation of democracy.

Thought that is silenced is always rebellious. Majorities, of course, are often mistaken. This is why the silencing of minorities is necessarily dangerous. Criticism and dissent are the indispensable antidote to major delusions.

Even when alternative views are clearly wrong, being exposed to them still expands our creative potential. In a way, the power of dissent is the power of surprise. After hearing someone shout out an errant answer, we work to understand it, which causes us to reassess our initial assumptions and try out new perspectives. “Authentic dissent can be difficult, but it’s always invigorating,” [Charlan] Nemeth [a professor of psychology at the University of California at Berkeley] says. “It wakes us right up.

You see a Party system that crushes down anybody who [has] different opinions, who has different ideas in their mind. Simply to have different opinions can cost someone their life. They can be put in jail, they can be silenced, and they can [disappear]. And the other people would take it, not giving support.

The dissent we witness is a reaffirmation of faith in man; it is protest against living under rules and prejudices and attitudes that produce the extremes of wealth and poverty and that make us dedicated to the destruction of people through arms, bombs, and gases, and that prepare us to think alike and be submissive objects for the regime of the computer.

Most of us are for freedom of expression when there’s a danger that our own views will be suppressed. We’re not all that upset, though, when views we despise encounter a little censorship here and there.

I don't think we should silence people just because their viewpoints are something we disagree with. There is value in the conversation, and we as a society need to confront these issues. This is an incredibly complex topic, and I'm sure our thinking will continue to evolve.

When people are intimidated about having their own opinions, oppression is at hand.

"To those who suspect that intellect is a subversive force in society, it will not do to reply that intellect is really a safe, bland, and emollient thing. In a certain sense, the suspicious Tories and militant philistines are right: intellect is dangerous. Left free, there is nothing it will not reconsider, analyze, throw into question. "Let us admit the case of the conservative," John Dewey once wrote. "If we once start thinking no one can guarantee what will be the outcome, except that many objects, ends and institutions will be surely doomed. Every thinker puts some portion of an apparently stable world in peril, and no one can wholly predict what will emerge in its place." Further, there is no way of guaranteeing that an intellectual class will be discreet and restrained in the use of its influence; the only assurance that can be given to any community is that it will be far worse off if it denies the free uses of the power of intellect than if it permits them. To be sure, intellectuals, contrary to the fantasies of cultural vigilantes, are hardly ever subversive of a society as a whole. But intellect is always on the move against something: some oppression, fraud, illusion, dogma, or interest is constantly falling under the scrutiny of the intellectual class and becoming the object of exposure, indignation, or ridicule."

Dissents speak to a future age. It's not simply to say, "My colleagues are wrong and I would do it this way." But the greatest dissents do become court opinions and gradually over time their views become the dominant view. So that's the dissenter's hope: that they are writing not for today but for tomorrow.

Intolerance of others’ views (no matter how ignorant or incoherent they may be) is not simply wrong; in a world where there is no right or wrong, it is worse: it is a sign you are embarrassingly unsophisticated or, possibly, dangerous.

Has there ever been a society which has died of dissent? Several have died of conformity in our lifetime.” Jacob Bronowski in Science and Human Values
