All the martyrs in the history of the world are not sufficient to establish the correctness of an opinion. Martyrdom, as a rule, establishes the sincerity of the martyr, — never the correctness of his thought. Things are true or false in themselves. Truth cannot be affected by opinions; it cannot be changed, established, or affected by martyrdom. An error cannot be believed sincerely enough to make it a truth.

You cannot change the conclusion of the brain by torture; nor by social ostracism. But I will tell you what you can do by these, and what you have done. You can make hypocrites by the million. You can make a man say that he has changed his mind; but he remains of the same opinion still. Put fetters all over him; crush his feet in iron boots; stretch him to the last gasp upon the holy rack; burn him, if you please, but his ashes will be of the same opinion still.

It is never to be expected in a revolution that every man is to change his opinion at the same moment. There never yet was any truth or any principle so irresistibly obvious that all men believed it at once.

To punish a man because he has committed a crime, or because he is believed, though unjustly, to have committed a crime, is not persecution. To punish a man, because we infer from the nature of some doctrine which he holds, or from the conduct of other persons who hold the same doctrines with him, that he will commit a crime, is persecution, and is, in every case, foolish and wicked.

The problem with ideology is, if you’ve got an ideology, you’ve already got your mind made up. You know all the answers and that makes evidence irrelevant and arguments a waste of time. You tend to govern by assertion and attacks.
On the necessary points, unity. On the questionable points, liberty. In everything, love.
[In necessariis unites, in non necessariis libertas, in omnibus caritas.]

Paraphrase of final lines of the work:
Verbo dicam: Si nos servaremus IN necesariis Unitatem, IN non-necessariis Libertatem, IN UTRISQUE Charitatem, optimo certe loco essent res nostrae.
[In a word, were we to observe unity in essentials, liberty in incidentals, and in all things charity, our affairs would be certainly in a most happy situation.]
Commonly attributed to St Augustine, but also to John Wesley, Richard Baxter, and several others.
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.

If in the last few years you haven’t discarded a major opinion or acquired a new one, check your pulse. You may be dead.

The substitution of force for persuasion, among its other disadvantages, has this further drawback, from our present point of view, that it lessens the conscience of a society and breeds hypocrisy. You have not converted a man, because you have silenced him.

For what a man had rather were true he more readily believes. Therefore he rejects difficult things from impatience of research; sober things, because they narrow hope; the deeper things of nature, from superstition; the light of experience, from arrogance and pride, lest his mind should seem to be occupied with things mean and transitory; things not commonly believed, out of deference to the opinion of the vulgar. Numberless, in short, are the ways, and sometimes imperceptible, in which the affections color and infect the understanding.

When I, a thoughtful and unblessed Presbyterian, examine the Koran, I know that beyond any question every Mohammedan is insane; not in all things, but in religious matters. When a thoughtful and unblessed Mohammedan examines the Westminster Catechism, he knows that beyond any question I am spiritually insane. I cannot prove to him that he is insane, because you never can prove anything to a lunatic — for that is a part of his insanity and the evidence of it. He cannot prove to me that I am insane, for my mind has the same defect that afflicts his. All Democrats are insane, but not one of them knows it; none but the Republicans and Mugwumps know it. All the Republicans are insane, but only the Democrats and Mugwumps can perceive it. The rule is perfect: in all matters of opinion our adversaries are insane.

From the same it proceedeth that men give different names to one and the same thing from the difference of their own passions: as they that approve a private opinion call it opinion; but they that mislike it, heresy: and yet heresy signifies no more than private opinion; but has only a greater tincture of choler.
With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think to-day in words as hard as cannon-balls and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day.
Full and free expression of the 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 the frank expression of conflicting opinions lies the greatest promise of wisdom in governmental action.
Error of opinion may be tolerated where reason is left free to combat it.

People who like this sort of thing will find this the sort of thing they like.
Abraham Lincoln (1809-1865) American lawyer, politician, US President (1861-65)
(Attributed)
One of the earliest references to something like this was in an 1863 newspaper ad for Lincoln’s favorite humorist, Artemus Ward, that included this faux testimonial (possibly written by Ward): “I have never heard any of your lectures, but from what I can learn I should say that for people who like the kind of lectures you deliver, they are just the kind of lectures such people like. Yours respectfully, O. Abe.”
Quoted in G.W.E. Russell, Collections and Recollections, ch. 30 (1898), regarding “an unreadably sentimental book.”
According to Anthony Gross, Lincoln’s Own Stories (1902), Lincoln’s was speaking to Robert Dale Owen, who had insisted on reading to Lincoln a long manuscript on spiritualism. "Well, for those who like that sort of thing, I should think it is just about the sort of thing they would like."
In Emanual Hertz, ed., "Father Abraham," Lincoln Talks: A Biography in Anecdote (1939), the response was to a young poet asking him about his newly published poems.

He who knows only his own side of the case, knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion. The rational position for him would be suspension of judgment, and unless he contents himself with that, he is either led by authority, or adopts, like the generality of the world, the side to which he feels most inclination.
