Montaigne, Michel de -- Essays, Book 2, ch. 17 (2.17), “Of Presumption [De la Presomption]” (1578) [tr. Frame (1943)]

Dave — Wed, 01 Apr 2026 21:44:08 +0000

Deliberation, even about the slightest things, annoys me; and I feel my mind harder put to it to endure the various shocks and ups and downs of doubt and deliberation, than to settle down and accept any course whatever, after the die is cast. Few passions have troubled my sleep; but as for deliberations, the slightest one troubles it.

[Le deliberer, voire és choses plus legeres, m’importune. Et sens mon esprit plus empesché à souffrir le bransle, & les secousses diverses du doute, & de la consultation, qu’à se rassoir & resoudre à quelque party que ce soit, apres que la chance est livree. Peu de passions m’ont troublé le sommeil ; mais des deliberations, la moindre me le trouble.]

(Source (French)). Alternate translations:

To deliberate, be it but in sleight matters, doth importune me. And I feele my spirit more perplexed to suffer the motions of doubt, and shakings of consultation, then to be settled and resolved about any accident whatsoever, after the chaunce is once cast. Fewe passions have troubled my sleep; but of deliberations the leaste doth trouble it.
[tr. Florio (1603)]

Deliberation, even in things of lightest moment, is very troublesome to me; and I find my mind more put to it, to undergo the various tumbling and tossing of doubt and consultation, than to set up its rest, and to acquiesce in whatever shall happen after the die is thrown. Few passions break my sleep; but, of deliberations, the least disturbs me.
[tr. Cotton (1686)]

Deliberation, even in things of lightest moment, is very troublesome to me; and I find my mind more put to it to undergo the various tumblings and tossings of doubt and consultation, than to set up its rest and to acquiesce in whatever shall happen after the die is thrown. Few passions break my sleep, but of deliberations, the least will do it.
[tr. Cotton/Hazlitt (1877)]

Deliberation, indeed, even in the most trivial things, importunes me; and I feel my mind more pestered in suffering the actions and diverse shocks of doubt and consultation than, after the die is cast, in settling down and resolving upon some course, whatever it may be. Few passions have ever disturbed my sleep, but the least deliberation troubles me.
[tr. Ives (1925)]

Deliberation, even in things of lightest moment, is vexatious to me; and I find my mind more put to it to bear up under the various agitations and disturbances of doubt and deliberation than in settling down and acquiescing in whatever shall happen after the die is thrown. Few passions have troubled my sleep, but of deliberations the slightest one will trouble it.
[tr. Zeitlin (1934)]

Deliberation, even in the most trivial affairs, is irksome to me; and my mind is more put about when suffering the shocks and trepidations of uncertainty and doubt than in settling down and accepting whatever happens, once the die is cast. My sleep has been broken by few passions; but the slightest suspense will break it.
[tr. Cohen (1958)]

It bothers me to make up my mind even about the most trivial things, and I feel my spirits more hard-pressed in suffering the swings of doubt and the diverse shocks of decision-making than in remaining fixed, resigned to any outcome whatsoever once the dice have been thrown. Few emotions have ever disturbed my sleep, yet even the slightest need to decide anything can disturb it for me.
[tr. Screech (1987)]

Ustinov, Peter -- Interview (1995-06-22) by Warren Allen Smith, Free Inquiry Magazine

I think that it’s an honorable thing to change your mind occasionally. I don’t think it’s a sign of weakness or lack of integrity. I believe men are united by their doubts and separated by their convictions. Therefore, it’s a very good thing to have doubts. Doubts are the greatest spur to activity that I know of.

Ingersoll, Robert Green -- Lecture (1872-01-29), “The Gods,” Fairbury Hall, Fairbury, Illinois

Dave — Fri, 14 Nov 2025 17:03:20 +0000

The instant we admit that a book is too sacred to be doubted, or even reasoned about, we are mental serfs. It is infinitely absurd to suppose that a god would address a communication to intelligent beings, and yet make it a crime, to be punished in eternal flames, for them to use their intelligence for the purpose of understanding his communication. If we have the right to use our reason, we certainly have the right to act in accordance with it, and no god can have the right to punish us for such action.

Liberty is often a heavy burden on a man. It involves that necessity for perpetual choice which is the kind of labor men have always dreaded. In common life we shirk it by forming habits, which take the place of self-determination. In politics party-organization saves us the pains of much thinking before deciding how to cast our vote. In religious matters there are great multitudes watching us perpetually, each propagandist ready with his bundle of finalities, which having accepted we may be at peace. The more absolute the submission demanded, the stronger the temptation becomes to those who have been long tossed among doubts and conflicts.

I once heard an orthodox person denouncing those who discuss articles of faith. “Gentlemen,” he said naïvely, “a true Christian does not examine what he is ordered to believe. Dogma is like a bitter pill: if you chew it, you will never be able to swallow it.”

[J’ai entendu un dévot, parlant contre des gens qui discutent des articles de foi, dire naïvement: «Messieurs, un vrai chrétien n’examine point ce qu’on lui ordonne de croire. Tenez, il en est de cela comme d’une pillule amère, si vous la mâchez, jamais vous ne pourrez l’avaler.»]

I once heard a pious person say naively, in arguing with people who were discussing articles of faith, "Sirs, a true Christian does not examine what he is instructed to believe. You see, it's like a bitter pill -- if you chew it, you'll never be able to swallow it."

I think nobody should be certain of anything. If you’re certain, you’re certainly wrong, because nothing deserves certainty, and so one ought always to hold all one’s beliefs with a certain element of doubt and one ought to be able to act vigorously in spite of the doubt.

Dave — Fri, 25 Feb 2022 19:18:39 +0000

Our secularism is hard-won, the product of centuries of political, intellectual, and sometimes physical courage. Secularism is the institutionalization of doubt, or more precisely of respect for doubt. It is harder to love doubt than to love freedom. So we are grudging about our secularism, and some of us are a little ashamed of it. Maybe it takes Rushdie’s nightmare and Khomeini’s rage to remind us how precious it is, and how fiercely it must be guarded.

Clifford, William Kingdon -- “The Ethics of Belief,” Part 1 “The Duty of Inquiry,” Lecture, London (11 Apr 1876)

Dave — Mon, 06 Dec 2021 16:27:42 +0000

Inquiry into the evidence of a doctrine is not to be made once for all, and then taken as finally settled. It is never lawful to stifle a doubt; for either it can be honestly answered by means of the inquiry already made, or else it proves that the inquiry was not complete.

“But,” says one, “I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments.” Then he should have no time to believe.

Dave — Mon, 15 Nov 2021 17:58:14 +0000

Every time we let ourselves believe for unworthy reasons, we weaken our powers of self-control, of doubting, of judicially and fairly weighing evidence. We all suffer severely enough from the maintenance and support of false beliefs and the fatally wrong actions which they lead to, and the evil born when one such belief is entertained is great and wide. But a greater and wider evil arises when the credulous character is maintained and supported, when a habit of believing for unworthy reasons is fostered and made permanent.

To know all about anything is to know how to deal with it under all circumstances. We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. And if we have supposed ourselves to know all about anything, and to be capable of doing what is fit in regard to it, we naturally do not like to find that we are really ignorant and powerless, that we have to begin again at the beginning, and try to learn what the thing is and how it is to be dealt with — if indeed anything can be learnt about it. It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting.

There are three essentials to Sŏn meditation. First of all, you must be rooted in Great Faith and Great Confidence. Secondly, one must have Great Anger -- a strong, inwardly-directed, ardent determination to practice. Thirdly, one must have Great Doubt. If one of these is missing, it is like a tripod vessel with one leg cut off -- in the end, it will be of no use.

It is well known that Ganhwaseon practitioners must have three things of essential importance: The first is a Foundation of Great Faith (大信根) for the practice which is possible; the second is Great Zealous Determination (大憤志) of practice to attain enlightenment; the third is a Great Feeling of Doubt (大疑情) on the Hwadu.

It would never come into their [the masses’] heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying.

The total moral collapse of respectable society during the Hitler regime may teach us that under such circumstances those who cherish values and hold fast to moral norms and standards are not reliable: we now know that moral norms and standards can be changed overnight, and that all that then will be left is the mere habit of holding fast to something.
Much more reliable will be the doubters and skeptics, not because skepticism is good or doubting wholesome, but because they are used to examine things and to make up their own minds.
Best of all will be those who know only one thing for certain: that whatever else happens, as long as we live we shall have to live together with ourselves.

Mencken, H. L. -- Minority Report : H.L. Mencken’s Notebooks, #418 (1956)

Dave — Tue, 28 Oct 2008 13:15:32 +0000

Moral certainty is always a sign of cultural inferiority. The more uncivilized a man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant in this field as in all others. His culture is based on “I am not too sure.”

Dave — Mon, 16 Jun 2008 10:59:47 +0000

To doubt one’s own first principles is the mark of a civilized man. Don’t defend past actions; what is right today may be wrong tomorrow. Don’t be consistent; consistency is the refuge of fools.

Wilcox, Ella Wheeler -- Poem (1906), “‘Credulity,'” st. 1-2, New Thought Pastels

Dave — Tue, 15 Jan 2008 10:26:30 +0000

If fallacies come knocking at my door,
I’d rather feed, and shelter full a score,
Than hide behind the black portcullis, doubt,
And run the risk of barring one Truth out.

And if pretension for a time deceive,
And prove me one too ready to believe,
Far less my shame, than if by stubborn act,
I brand as lie, some great colossal Fact.

Russell, Bertrand -- “The Triumph of Stupidity,” New York American (1933-05-10)

Dave — Sun, 01 Feb 2004 16:00:00 +0000

Brute force plays a much larger part in the government of the world than it did before 1914, and what is especially alarming, force tends increasingly to fall into the hands of those who are enemies of civilization. The danger is profound and terrible; it cannot be waved aside with easy optimism. The fundamental cause of the trouble is that in the modern world the stupid are cocksure while the intelligent are full of doubt.

Bertrand Russell (1872-1970) English mathematician and philosopher
“The Triumph of Stupidity,” New York American (1933-05-10)

Often paraphrased, "The trouble with the world is that the stupid are cocksure, and the intelligent are full of doubt." See also Yeats and Bukowski.

Russell, Bertrand -- (Attributed)

Dave — Sun, 01 Feb 2004 16:00:00 +0000

In all affairs — love, religion, politics or business — it’s a healthy idea, now and then, to hang a question mark on the things you have long taken for granted.

Bertrand Russell (1872-1970) English mathematician and philosopher
(Attributed)

Widely attributed to Russell, but not found in any of his online published works or cited to any source.

There are numerous variations on this quote, e.g.,

In all affairs it's a healthy idea now and then to hang a question mark on the things you have taken for granted.

And mixes and matches between those two.

Earliest references of long-form quotation I could find:

I also found in Alexander Chittick, Social Evolution, "The Evolution of Capital and Labor" (1919), regarding the plight of laborers:

They should be taught [...] to take nothing for granted in love, religion, politics, or business.

The combination of taking for granted and the same list of four affair topics seems more than coincidence. Was Chittick riffing off of an unfound Russell comment? Did someone attribute a variation of Chittick's passage to Russell? The answer is unclear.

Those who believe that they believe in God, but without passion in their hearts, without anguish in mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God idea, not in God Himself.

Shake off all the fears and servile prejudices under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion.
