Quotes & Sayings About Scepticism

He had found the thing which the modern people call Impressionism, which is another name for that final scepticism which can find no floor to the universe. — G.K. Chesterton

I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours. — Stephen Roberts

When we are tired or preoccupied - what psychologists call 'resource-depleted' - we start to economise, to conserve those resources. Higher-order thinking is more expensive. So too is doubt, scepticism, arugment. 'Resource depletion specifically disables cognitive elaboration,' wrote Harvard psychologist Daniel Gillbert ... Because it takes less brain power to believe than to doublt, we are, when tired or distracted, gullible. Because we are all biased, and biases are quick and effortless, exhaustion tends to make us prefer the information we know and are comfortable with. We are too tired to do the heavier lifting of examining new or contradictory information, so we fall back on our biases the opinions and the people we already trust — Margaret Heffernan

There is, indeed a more mitigated scepticism or academical philosophy, which may be both durable and useful, and which may, in part, be the result of this Pyrrhonism, or excessive scepticism, when its undistinguished doubts are corrected by common sense and reflection. — David Hume

My main reason for scepticism about the Huxley/Sagan theory is that the human brain is demonstrably eager to see faces in random patterns, as we know from scientific evidence, on top of the numerous legends about faces of Jesus, or the Virgin Mary, or Mother Teresa, being seen on slices of toast, or pizzas, or patches of damp on a wall. This eagerness is enhanced if the pattern departs from randomness in the specific direction of being symmetrical. — Richard Dawkins

The greatest challenge that has surreptitiously arisen in our age is the challenge of knowledge, indeed, not as against ignorance; but knowledge as conceived and disseminated throughout the world by Western civilization; knowledge whose nature has become problematic because it has lost its true purpose due to being unjustly conceived, and has thus brought about chaos in man's life instead of, and rather than, peace and justice; knowledge which pretends to be real but which is productive of confusion and scepticism, which has elevated doubt and conjecture to the 'scientific' rank in methodology; knowledge which has, for the first time in history, brought chaos to the Three Kingdom of Nature; the animal, vegetal and mineral. — Syed Muhammad Naquib Al-Attas

Why should each generation be brought up on the selective prejudices of the one before it? I believe that this is exactly the point of history. And not just reading or studying history but also approaching it with a sceptical bent of mind. When each generation approaches received wisdom with scepticism, perhaps it will reassess established notions of right and wrong, love and hate. Perhaps it will finally see mistaken priorities for what they really are. Perhaps it will do something that previous generations steadfastly refused to do. — Sidin Vadukut

Hobbes is not an absolutist precisely because he is an authoritarian. His scepticism about the power of reasoning, which applied no less to the 'artificial reason' of the Sovereign than to the reasoning of the natural man, together with the rest of his individualism, separate him from the rationalist dictators of his or any age. Indeed, Hobbes, without being himself a liberal, had in him more of the philosophy of liberalism than most of its professed defenders — Efraim Podoksik

Scientific knowledge advances haltingly and is stimulated by contention and doubt. — Claude Levi-Strauss

The great subverter of Pyrrhonism or the excessive principles of scepticism is action, and employment, and the occupations of common life. — David Hume

Scepticism is effortful and costly. It is better to be sceptical about matters of large consequences, and be imperfect, foolish and human in the small and the aesthetic. — Nassim Nicholas Taleb

Is it really for love he is going to marry you?" She asked.
I was so hurt by her coldness and scepticism that the tears rose to my eyes.
"I am sorry to grieve you," pursued the widow; "but you are so young, and so little acquainted with men, I wished to put you on your guard. It is an old saying that 'all is not gold that glitters;' and in this case I do fear there will be something found to be different to what either you or I expect. — Charlotte Bronte

Usually they looked past me hopefully and some even went and peered into the car to see if the man they really wanted was hiding in there. And it was uphill work examining an animal when its owner was chafing in the background, wishing with all his heart that I was somebody else. But I had to admit they were fair. I got no effusive welcomes and when I started to tell them what I thought about the case they listened with open scepticism, but I found that if I got my jacket off and really worked at the job they began to thaw a little. — James Herriot

Scepticism is always a back road leading to some credo or other. — Mason Cooley

The human understanding is a revelation from its maker, which can never be disputed or doubted. There can be no scepticism, Pyrrhonism, or incredulity or infidelity here. No prophecies, no miracles are necessary to prove this celestical communication. This revelation has made it certain that two and one make three, and that one is not three nor can three be one. We can never be so certain of any prophecy, or the fulfilment of any prophecy, or of any miracle, or the design of any miracle, as we are from the revelation of nature, that is, nature's God, that two and two are equal to four. — John Adams

In all the events of life, we ought still to preserve our scepticism. If we believe that fire warms, or water refreshes, it is only because it costs us too much pains to think otherwise. — David Hume

We have an idea of truth, invincible to all scepticism. — Blaise Pascal

Most people don't believe something can happen until it already has. That's not stupidity or weakness, that's just human nature. — Max Brooks

It could always all be unreal - how could you ever tell otherwise? You took it on trust, in part because what would be the point of doing anything else? When the fake behaved exactly like the real, why treat it as anything different? You gave it the benefit of the doubt, until something proved otherwise. — Iain M. Banks

Sometimes I think I am going mad. I live for days in the mystery and tears of things so that the commonest object, the most familiar face- even my own- become ghostly, unreal, enigmatic. I get into an attitude of almost total scepticism, nescience, solipsism, in a world of dumb, sphinx-like things that cannot explain themselves. The discovery of how I am situated- a sentient being on a globe in space overshadows me. I wish I were just nothing. — W.N.P. Barbellion

We must be sceptical even of our scepticism. — Bertrand Russell

The uneducated relatives of our patients - persons who are impressed only by the visible and tangible, preferably by such procedure as one sees in the moving picture theatres - never miss an opportunity of voicing their scepticism as to how one can "do anything for the malady through mere talk." Such thinking, of course, is as shortsighted as it is inconsistent. For these are the very persons who know with such certainty that the patients "merely imagine" their symptoms. Words — Sigmund Freud

There is no steady unretracing progress in this life; we do not advance through fixed gradations, and at the last one pause: - through infancy's unconscious spell, boyhood's thoughtless faith, adolescence' doubt (the common doom). and then scepticism, then disbelief, resting at last in manhood's pondering repose of If. — Herman Melville

If there is, to be sure, something more terrifying than the history of the fall of great empires, it is the history of the death of religions. Volney himself was overcome by this feeling as he visited the innumerable ruins of once-sacred buildings. The true believer may still escape from this impression, but with the inherent scepticism of our age all of us must sometime tremble to find so many dark gates opening out on to nothingness. — Gerard De Nerval

Most people are too silly to be truly interested in any thing. They herd together like cattle, and do not know what is good for them. — Frank R. Stockton

The want of faith, as well as faith itself, is best shewn by works. If a sceptic avoid the fire as much as those who believe it dangerous to go into it, we can hardly avoid thinking his scepticism to be feigned, and not real. — Thomas Reid

A Christian telling an atheist they're going to hell is as scary as a child telling an adult they're not getting any presents from Santa. — Ricky Gervais

Don't believe anything you read on the net. Except this. Well, including this, I suppose. — Douglas Adams

scepticism by means of classical arguments, the most effective means initially to promote arousal. And, — Peter Unger

We are talking about a bet, remember, and Pascal wasn't claiming that his wager enjoyed anything but very long odds. Would you bet on God's valuing dishonestly faked belief (or even honest belief) over honest scepticism? — Richard Dawkins

Moral scepticism can no more be refuted or proved by logic than intellectual scepticism can. When we stick to it that there is truth (be it of either kind), we do so with our whole nature, and resolve to stand or fall by the results. The sceptic with his whole nature adopts the doubting attitude; but which of us is the wiser, Omniscience only knows. — William James

Nothing fortifies scepticism more than the fact that there are some who are not sceptics; if all were so, they would be wrong. — Blaise Pascal

Modest doubt is call'd the beacon of the wise. — William Shakespeare

If you're only sceptical, then no new ideas make it through to you. You never learn anything. You become a crochety misanthrope convinced that nonsense is ruling the world. (There is, of course, much data to support you.) Since major discoveries in the borderlines of science are rare, experience will tend to confirm your grumpiness. But every now and then a new idea turns out to be on the mark, valid and wonderful. If you're too resolutely and uncompromisingly sceptical, you're going to miss (or resent) the transforming discoveries in science, and either way you will be obstructing understanding and progress. Mere scepticism is not enough. — Carl Sagan

The causes of any widespread scepticism are likely to be sociological rather than intellectual. The main cause is always comfort without power. The holders of power are not cynical, since they are able to enforce their ideals. Victims of oppression are not cynical, since they are filled with hate, and hate, like any other strong passion, brings with it a train of attendant beliefs. — Bertrand Russell

Unwilling wholly to abandon the project for which his wife had died, unable to maintain any longer the absolute belief which the enterprise required, Muhammad Din entered the station wagon of scepticism. — Salman Rushdie

Scepticism is never certain of itself, being less a firm intellectual position than a pose to justify bad behavior. — Fulton J. Sheen

Latter-day scepticism is fond of calling itself progressive; but scepticism is really reactionary. Scepticism goes back; it attempts to unsettle what has already been settled. Instead of trying to break up new fields with its plough, it simply tries to break up the plough. — G.K. Chesterton

The shadow of scepticism is dispelled in the light of real knowledge. — Etienne De L'Amour

Johnson is a radical skeptic, insisting, in the best Socratic tradition, that everything be put on the table for examination. By contrast, most skeptics opposed to him are selective skeptics, applying their skepticism to the things they dislike (notably religion) and refusing to apply their skepticism to the things they do like (notably Darwinism). On two occasions I've urged Michael Shermer, publisher of Skeptic Magazine, to put me on its editorial board as the resident skeptic of Darwinism. Though Shermer and I know each other and are quite friendly, he never got back to me about joining his editorial board. — William A. Dembski

Both the fanatical believers and the fixed attitude people are loud in their scorn of what they call "woolly minds." ... [But it] is the woolly mind that combines scepticism about everything with credulity about everything. Being woolly it has no hard edges. It is easy, pliant, yet it has its own toughness. Because it bends, it does not break. ... The woolly mind realizes that we live in an unimaginable gigantic, complicated, mysterious universe. To try to stuff the vast bewildering creation into a few neat pigeon-holes is absurd. We don't know enough, and to pretend we do is mere intellectual conceit. ... The best we can do is keep looking out for clues, for anything that will light us a step or two in the dark. — J.B. Priestley

As long as scepticism is based on a sound understanding of science it is invaluable, for that is how science progresses. But poor criticism can lead those who are unfamiliar with the science involved into doubting everything about climate change predictions. — Tim Flannery

Each new ontological theory, propounded in lieu of previous ones shown to be untenable, has been followed by a new criticism leading to a new scepticism. All possible conceptions have been one by one tried and found wanting; and so the entire field of speculation has been gradually exhausted without positive result: the only result reached being the negative one above stated, that the reality existing behind all appearances is, and must ever be, unknown. — Herbert Spencer

A truth now and then projecting into the ocean of newspaper lies serves like headlands to correct our course. Indeed, my scepticism as to everything I see in a newspaper makes me indifferent whether I ever see one. — Thomas Jefferson

It seems to me that they only seem to mention things in the Bible that are within a 5 mile radius of the guy writing it. — Jim Jefferies

Historians need to treat a participant's own explanation of events with a certain scepticism. It is often the statement made with an eye to the future that is the most suspect. — Julian Barnes

I am not a committed pacifist. I would not hold that it is under all imaginable circumstances wrong to use violence, even though use of violence is in some sense unjust. I believe that one has to estimate relative justices. But the use of violence and the creation of some degree of injustice can only be justified on the basis of the claim and the assessment-which always ought to be undertaken very, very seriously and with a good deal of scepticism that this violence is being exercised because a more just result is going to be achieved. — Noam Chomsky

What of Art?
-It is a malady.
Love?
-An Illusion.
Religion?
-The fashionable substitute for Belief.
You are a sceptic.
-Never! Scepticism is the beginning of Faith.
What are you?
-To define is to limit. — Oscar Wilde

How do you give something away with the knowledge that you will get it back in three days, and then claim it to be the 'Ultimate Sacrifice'? — Jake Jesser

Whatever your career may be, do not let yourselves become tainted by a deprecating and barren scepticism, do not let yourselves be discouraged by the sadness of certain hours which pass over nations. Live in the serene peace of laboratories and libraries. Say to yourselves first : ' What have I done for my instruction ? ' and , as you gradually advance, 'What have I done for my country?' until the time comes when you may have the immense happiness of thinking that you have contributed in some way to the progress and to the good of humanity. But, whether our efforts are or not favoured by life, let us be able to say, when we come near the great goal, ' I have done what I could — Louis Pasteur

For better or worse we're in an age of disbelief," Rico said, "An age of science and a need for proof. — Bryan Islip

There's a certain kind of scepticism that can't bear uncertainty. — Rupert Sheldrake

The expression 'to lose one's faith', as one might a purse or a ring of keys, has always seemed to me rather foolish. It must be one of those sayings of bourgeois piety, a legacy of those wretched priests of the eighteenth century who talked so much.

Faith is not a thing which one 'loses', we merely cease to shape our lives by it. That is why old-fashioned confessors are not far wrong in showing a certain amount of scepticism when dealing with 'intellectual crises', doubtless far more rare than people imagine. An educated man may come by degrees to tuck away his faith in some back corner of his brain, where he can find it again on reflection, by an effort of memory: yet even if he feels a tender regret for what no longer exists and might have been, the term 'faith' would nevertheless be inapplicable to such an abstraction, no more like real faith, to use a very well-worn simile, than the constellation of Cygne is like a swan. — Georges Bernanos

[Charles] Nodier's later view was that fantasy reconciles men to their fate. Fantasy and the taste for chimeras, he wrote, are symptoms of a time of political decay and transition, when the unpleasant realities of political life are too hard to bear. They serve a useful purpose in that they give men hope when scepticism and disillusion would otherwise drive them to despair. — Peter Partner

We have known for a long time that Prince Charles' empty sails are so rigged as to be swelled by any passing waft or breeze of crankiness and cant. He fell for the fake anthropologist Laurens van der Post. He was bowled over by the charms of homeopathic medicine. He has been believably reported as saying that plants do better if you talk to them in a soothing and encouraging way. — Christopher Hitchens

There once was a time when all people believed in God and the church ruled. This time was called the Dark Ages. — Richard Lederer

If we offer too much silent assent about mysticism and superstition - even when it seems to be doing a little good - we abet a general climate in which scepticism is considered impolite, science tiresome, and rigorous thinking somehow stuffy and inappropriate. Figuring out a prudent balance takes wisdom. — Carl Sagan

The three main sources of scepticism are first, that not every people desires freedom; second, that democracy in certain parts of the world would be dangerous; and third, that there is little the world's democracies can do to advance freedom outside their countries. — Natan Sharansky

Scepticism is the first step towards truth. — Denis Diderot

There is but one indefectibly certain truth , and that is the truth that pyrrhonistic scepticism itself leaves standing, the truth that the present phenomenon of consciousness exists. — William James

And so there was a fundamental scepticism about the ability of any institution, even one like the novel, to tell us anything true. — Garth Risk Hallberg

The terrible error in the course of human civilization is undoubtedly the defective judgment that allowed religious authorities usurp the foundation of societal morality, in which all collective ethics of humankind must take a cause. This appalling blunder is comparable only to assigning the leper exclusive franchise to run beauty clinics in the society; this can only lead to cycles upon cycles of common infection syndrome. — Adebowale Ojowuro

The merits and services of Christianity have been industriously extolled by its hired advocates. Every Sunday its praises are sounded from myriads of pulpits. It enjoys the prestige of an ancient establishment and the comprehensive support of the State. It has the ear of rulers and the control of education. Every generation is suborned in its favor. Those who dissent from it are losers, those who oppose it are ostracised; while in the past, for century after century, it has replied to criticism with imprisonment, and to scepticism with the dungeon and the stake. By such means it has induced a general tendency to allow its pretensions without inquiry and its beneficence without proof. — Joseph Mazzini Wheeler

The deepest, the only theme of human history, compared to which all others are of subordinate importance, is the conflict of scepticism with faith. — Johann Wolfgang Von Goethe

A state of scepticism and suspense may amuse a few inquisitive minds. But the practice of superstition is so congenial to the multitude, that if they are forcibly awakened, they still regret the loss of their pleasing vision. Their love of the marvellous and supernatural, their curiosity with regard to future events, and their strong propensity to extend their hopes and fears beyond the limits of the visible world, were the principal causes which favoroud the establishment of Polytheism. So urgent on the vulgar is the necessity of believing, that the fall of any system of mythology will most probably be succeeded by the introduction of some other mode of superstition. ( ... ) an object much less deserving would have been sufficient to fill the vacant place in their hearts. — Edward Gibbon

The majority of mankind is lazy-minded, incurious, absorbed in vanities, and tepid in emotion, and is therefore incapable of either much doubt or much faith. — T. S. Eliot

What is it you most dislike? Stupidity, especially in its nastiest forms of racism and superstition. — Christopher Hitchens

The more she rejected us the more convinced I was that she was another version of the real Molly, her disdain for authority, her scepticism that she had to do what the white man told her because it was good for her ... She is Molly. — Phillip Noyce

She believed in nothing. Only her scepticism kept her from being an atheist. — Jean-Paul Sartre

As its best, SF is the medium in which our miserable certainty that tomorrow will be different from today in ways we cant predict, can be transmuted to a sense of excitement and anticipation, occasionally evolving into awe. Poised between intransigent scepticism and uncritical credulity, it is par excellence the literature of the open mind. — John Brunner

Does a man of sense run after every silly tale of hobgoblins or fairies, and canvass particularly the evidence? I never knew anyone, that examined and deliberated about nonsense who did not believe it before the end of his enquiries. — David Hume

...the scepticism of men, who do not truly believe in new things unless they have actually had personal experience of them. — Niccolo Machiavelli

I have wrestled with death. It is the most unexciting contest you can imagine. It takes place in an impalpable greyness, with nothing underfoot, with nothing around, without spectators, without clamour, without glory, without the great desire of victory, without the great fear of defeat, in a sickly atmostphere of tepid scepticism, without much belief in your own right, and still less in that of your adversary. — Joseph Conrad

I began to entertain a suspicion, that no man in this age was sufficiently qualified for such an undertaking; and that whatever any one should advance on that head would, in all probability, be refuted by further experience, and be rejected by posterity. Such mighty revolutions have happened in human affairs, and so many events have arisen contrary to the expectation of the ancients, that they are sufficient to beget the suspicion of still further changes. — David Hume

Liberty has produced scepticism, and scepticism has destroyed liberty. The lovers of liberty thought they were leaving it unlimited, when they were only leaving it undefined. They thought they were only leaving it undefined, when they were really leaving it undefended. — Gilbert K. Chesterton

The history of science alone can keep the physicist from the mad ambitions of dogmatism as well as the despair of pyrrhonian scepticism. — Pierre Duhem

In the controversy that followed the prince's remarks, his most staunch defender was professor John Taylor, a scholar whose work I had last noticed when he gave good reviews to the psychokinetic (or whatever) capacities of the Israeli conjuror and fraud Uri Geller. The heir to the throne seems to possess the ability to surround himself - perhaps by some mysterious ultramagnetic force? - with every moon-faced spoon-bender, shrub-flatterer, and water-diviner within range. — Christopher Hitchens

Often, superstition and injustice are imposed by the same ecclesiastical and secular authorities, working hand in glove. It is no surprise that political revolutions, scepticism about religion, and the rise of science might go together, — Carl Sagan

In the way that scepticism is sometimes applied to issues of public concern, there is a tendency to belittle, to condescend, to ignore the fact that, deluded or not, supporters of superstition and pseudoscience are human beings with real feelings, who, like the sceptics, are trying to figure out how the world works and what our role in it might be. Their motives are in many cases consonant with science. If their culture has not given them all the tools they need to pursue this great quest, let us temper our criticism with kindness. None of us comes fully equipped. — Carl Sagan

It is true that 'I seem to see a table' does not entail 'I see a table'; but 'I seem to feel a pain' does entail 'I feel a pain'. So scepticism loses its force - cannot open up its characteristic gap - with regard to that which ultimately most concerns us, pleasure and pain. — Galen Strawson

Not to grow up properly is to retain our 'caterpillar' quality from childhood (where it is a virtue) into adulthood (where it becomes a vice). In childhood our credulity serves us well. It helps us to pack, with extraordinary rapidity, our skulls full of the wisdom of our parents and our ancestors. But if we don't grow out of it in the fullness of time, our caterpillar nature makes us a sitting target for astrologers, mediums, gurus, evangelists and quacks. The genius of the human child, mental caterpillar extraordinary, is for soaking up information and ideas, not for criticizing them. If critical faculties later grow it will be in spite of, not because of, the inclinations of childhood. The blotting paper of the child's brain is the unpromising seedbed, the base upon which later the sceptical attitude, like a struggling mustard plant, may possibly grow. We need to replace the automatic credulity of childhood with the constructive scepticism of adult science. — Richard Dawkins

Scepticism, ironically, draws its life's blood from claims to have a good deal of knowledge. For example, your friends claim to know, 'Since every possible option has not been explored, nothing can be said for certain.' That statement is itself a claim to knowledge! — William Lane Craig

It has often been argued that absolute scepticism is self-contradictory; but this is a mistake: and even if it were not so, it would be no argument against the absolute sceptic, inasmuch as he does not admit that no contradictory propositions are true. Indeed, it would be impossible to move such a man, for his scepticism consists in considering every argument and never deciding upon its validity; he would, therefore, act in this way in reference to the arguments brought against him. — Charles Sanders Peirce

Colour, Figure, Motion, Extension and the like, considered only so many Sensations in the Mind, are perfectly known, there being nothing in them which is not perceived. But if they are looked on as notes or Images, referred to Things or Archetypes existing without the Mind, then are we involved all in Scepticism. — George Berkeley

What else would they be?"
"No idea." Arik shrugged ... "Aliens, mabye?"
"Aliens." Thanatos's voice was flat, disbelieving.
"Your scepticism is funny, coming from one of the Four fucking Horsemen of the Apocalypse. — Larissa Ione

Scepticism is a necessary and vital part of the journalist's toolkit. But when scepticism becomes cynicism it can close off thought and block the search for truth. — Jeremy Paxman

Yes, the laws of self-preservation and of self-destruction are equally powerful in this world. The devil will hold his empire over humanity until a limit of time which is still unknown. You laugh? You do not believe in the devil? Scepticism as to the devil is a French idea, and it is also a frivolous idea. Do you know who the devil is? Do you know his name? Although you don't know his name you make a mockery of his form, following the example of Voltaire. You sneer at his hoofs, at his tail, at his horns - all of them the produce of your imagination! In reality the devil is a great and terrible spirit, with neither hoofs, nor tail, nor horns; it is you who have endowed him with these attributes! But ... he is not the question just now! — Fyodor Dostoyevsky

I've lost all capacity for disbelief. I'm not sure that I could even rise to a little gentle scepticism. — Tom Stoppard

There was no sign of Plato, and I was told later that he had gone to live in his Republic, where he was cheerfully submitting to his own Laws. [ ... ] None of the Stoics were present. Rumour had it that they were still clambering up the steep hill of Virtue [ ... ]. As for the Sceptics, it appeared that they were extremely anxious to get there, but still could not quite make up their minds whether or not the island really existed. — Lucian Of Samosata

Philosophy arises from an unusually obstinate attempt to arrive at real knowledge. What passes for knowledge in ordinary life suffers from three defects: it is cocksure, vague and self-contradictory. The first step towards philosophy consists in becoming aware of these defects, not in order to rest content with a lazy scepticism, but in order to substitute an amended kind of knowledge which shall be tentative, precise and self-consistent. — Bertrand Russell

Scepticism is as important for a good journalist as it is for a good scientist. — Freeman Dyson

Scepticism, like wisdom, springs out in full panoply only from the brain of a god, and it is little profit to see an idea in its growth, unless we track its seed to the power which sowed it. — James Anthony Froude

What's the greatest enemy of Christianity to-day? Frozen meat. In the past only members of the upper classes were thoroughly sceptical, despairing, negative. Why? Among other reasons, because they were the only people who could afford to eat too much meat. Now there's cheap Canterbury lamb and Argentine chilled beef. Even the poor can afford to poison themselves into complete scepticism and despair. — Aldous Huxley

Scepticism, as we know, can never be thoroughly applied, else life would come to a standstill — George Eliot

And indeed nothing but the most determined scepticism, along with a great degree of indolence, can justify this aversion to metaphysics. For if truth be at all within the reach of human capacity, it is certain it must lie very deep and abstruse: and to hope we shall arrive at it without pains, while the greatest geniuses have failed with the utmost pains, must certainly be esteemed sufficiently vain and presumptuous. I pretend to no such advantage in the philosophy I am going to unfold, and would esteem it a strong presumption against it, were it so very easy and obvious. — David Hume

You know what they call alternative medicine that's been proved to work? - Medicine. — Tim Minchin

I am not suggesting that history or scepticism by themselves can provide all the answers to all these questions. History, after all, is not a forward-looking discipline. It can only tell us what happened the last time, not what will happen next time. Similarly, scepticism is hardly sufficient to do anything but ask questions. But together they - history and scepticism - form a potent force for enquiry. — Sidin Vadukut

A major problem for Black women, and all people of color, when we are challenged to oppose anti-Semitism, is our profound scepticism that white people can actually be oppressed. — Barbara Smith

Oxford also taught me something else - it taught me scepticism. — Frank Scott

One hardly knows which is the more appalling: the abjectness of the credulity or the flippancy of the scepticism.
- Shaw's Preface — George Bernard Shaw
