Disagreement is not oppression. Argument is not assault. Words – even provocative or repugnant ones – are not violence. The answer to speech we do not like is more speech.

I could never divide myself from any man upon the difference of an opinion, or be angry with his judgement for not agreeing with me in that, from which perhaps within a few days I should dissent myself.

An orator whose purpose is to persuade men must speak the things they wish to hear; an orator, whose purpose is to move men, must also avoid disturbing the emotional effect by any obtrusion of intellectual antagonism; but an author whose purpose is to instruct men, who appeals to the intellect, must be careless of their opinions, and think only of truth. It will often be a question when a man is or is not wise in advancing unpalateable opinions, or in preaching heresies; but it can never be a question that a man should be silent if unprepared to speak the truth as he conceives it. Deference to popular opinion is one great source of bad writing, and is all the more disastrous because the deference is paid to some purely hypothetical requirement. When a man fails to see the truth of certain generally accepted views, there is no law compelling him to provoke animosity by announcing his dissent. He may be excused if he shrink from the lurid glory of martyrdom; he may be justified in not placing himself in a position of singularity. He may even be commended for not helping to perplex mankind with doubts which he feels to be founded on limited and possibly erroneous investigation. But if allegiance to truth lays no stern command upon him to speak out his immature dissent, it does lay a stern command not to speak out hypocritical assent.

I would not have the reader conclude that because I advocate plain-speaking even of unpopular views, I mean to imply that originality and sincerity are always in opposition to public opinion. There are many points both of doctrine and feeling in which the world is not likely to be wrong. But in all cases it is desirable that men should not pretend to believe opinions which they really reject, or express emotions they do not feel. And this rule is universal. Even truthful and modest men will sometimes violate the rule under the mistaken idea of being eloquent by means of the diction of eloquence. This is a source of bad Literature.

When I hear another express an opinion which is not mine, I say to myself, he has a right to his opinion, as I to mine. Why should I question it? His error does me no injury, and shall I become a Don Quixote, to bring all men by force of argument to one opinion? ...Be a listener only, keep within yourself, and endeavor to establish with yourself the habit of silence, especially in politics.

I don't believe that walking out is the best way to express dissent or disagreement with people on certain issues.

...never [enter] into dispute or argument with another. I never saw an instance of one of two disputants convincing the other by argument. I have seen many, on their getting warm, becoming rude, & shooting one another. ... When I hear another express an opinion which is not mine, I say to myself, he has a right to his opinion, as I to mine; why should I question it? His error does me no injury, and shall I become a Don Quixote, to bring all men by force of argument to one opinion? ... There are two classes of disputants most frequently to be met with among us. The first is of young students, just entered the threshold of science, with a first view of its outlines, not yet filled up with the details & modifications which a further progress would bring to their knoledge. The other consists of the ill-tempered & rude men in society, who have taken up a passion for politics. ... Consider yourself, when with them, as among the patients of Bedlam, needing medical more than moral counsel. Be a listener only, keep within yourself, and endeavor to establish with yourself the habit of silence, especially on politics. In the fevered state of our country, no good can ever result from any attempt to set one of these fiery zealots to rights, either in fact or principle. They are determined as to the facts they will believe, and the opinions on which they will act. Get by them, therefore, as you would by an angry bull; it is not for a man of sense to dispute the road with such an animal.

"The modern habit of saying "This is my opinion, but I may be wrong" is entirely irrational. If I say that it may be wrong, I say that is not my opinion. The modern habit of saying "Every man has a different philosophy; this is my philosophy and it suits me" – the habit of saying this is mere weak-mindedness. A cosmic philosophy is not constructed to fit a man; a cosmic philosophy is constructed to fit a cosmos. A man can no more possess a private religion than he can possess a private sun and moon."

I am not an atheist, but I cannot agree with men who talk about God as if He had once attended a Speech Day at their theological college.

But every difference of opinion is not a difference of principle.

Toutes les opinions ne se valent pas, et il ne faut pas confondre l'éloquence d'une parole avec la justesse d'une pensée.

That is just my dissenting opinion, which I don’t conceive of as an “attack”. I find differences of opinion quite normal, the very stuff of intellectual life, and those who can only see them as attacks are not intellectuals.

Try not to force your idea on someone, but rather think about it with him. If you feel you have won the discussion, that also is the wrong attitude. Try not to win in the argument; just listen to it; but it is also wrong to behave as if you had lost. Usually when we say something, we are apt to try to sell our teaching or force our idea. But between Zen students there is no special purpose in speaking or in listening. Sometimes we listen, sometimes we talk; that is all. It is like a greeting: “Good morning!” Through this kind of communication we can develop our way.
