Quotes & Sayings About Conjecture

From the almost total absence of fossil evidence relative to the origin of the phyla, it follows that any explanation of the mechanism in the creative evolution of the fundamental structural plans is heavily burdened with hypothesis. This should appear as an epigraph to every book on evolution. The lack of direct evidence leads to the formulation of pure conjecture as to the genesis of the phyla; we do not even have a basis to determine the extent to which these opinions are correct. — Pierre-Paul Grasse

A man that is of Copernicus' Opinion, that this Earth of ours is a Planet, carry'd round and enlightn'd by the Sun, like the rest of them, cannot but sometimes have a fancy ... that the rest of the Planets have their Dress and Furniture, nay and their Inhabitants too as well as this Earth of ours. ... But we were always apt to conclude, that 'twas in vain to enquire after what Nature had been pleased to do there, seeing there was no likelihood of ever coming to an end of the Enquiry ... but a while ago, thinking somewhat seriously on this matter (not that I count my self quicker sighted than those great Men [of the past], but that I had the happiness to live after most of them) me thoughts the Enquiry was not so impracticable nor the way so stopt up with Difficulties, but that there was very good room left for probable Conjectures. — Christiaan Huygens

OBSERVATORY, n. A place where astronomers conjecture away the guesses of their predecessors. — Ambrose Bierce

The artist may be well advised to keep his work to himself till it is completed, because no one can readily help him or advise him with it.. but the scientist is wiser not to withhold a single finding or a single conjecture from publicity. — Johann Wolfgang Von Goethe

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

Now, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are skillful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted & carried out, lead to welfare & to happiness' - then you should enter & remain in them.

[Kalama Sutta, AN 3.65] — Gautama Buddha

Sect. 32. Hawaiian authorities are able to throw no light, and conjecture, but little light upon the true meaning of Ia. It is evidently the name or appellation of, or stands to represent, some deity. (The only name of a deity corresponding in form to this is the Hebrew JAH. Ps. 68: 4.) — David Malo

Unless we encounter God, speculating about God becomes nothing more than abstract conjecture and theorizing that has little impact on daily life. — N Graham Standish

There is no room in History for conjecture. History is fact because it deals with facts, you'll learn in time ... '
'Fuck that, man. That's like saying botany is a lettuce because it deals with lettuces. — D.L. Christopher

God is a conjecture: but I do not wish your conjecturing to reach beyond your creating will. Could ye CREATE a God? - Then, I pray you, be silent about all Gods! But ye could well create the Superman. — Friedrich Nietzsche

Why did Freud write a book about which he had such doubts? We can only conjecture. Peter Gay wrote that "it is highly plausible that some of the impulses guiding Freud's arguments in Totem and Taboo emerged from his hidden life; in some respects the book represents a round in his never finished wrestling bout with Jacob Freud." Gay also mentions that Freud realized he was "publishing scientific fantasies. — Armand M. Nicholi Jr.

Your tools have elevated gossip, hearsay and conjecture to the level of valid, mainstream communication. And besides that, it's fucking dorky. Mae exhaled — Dave Eggers

Intolerance and superstition has always been the domain of the more stupid amongst the common folk and, I conjecture, will never be uprooted, for they are as eternal as stupidity itself. There, where mountains tower today, one day there will be seas; there where today seas surge, will one day be deserts. But stupidity will remain stupidity. Nicodemus de Boot, Meditations on life, Happiness and Prosperity — Andrzej Sapkowski

In science's pecking order, evolutionary biology lurks somewhere near the bottom, far closer to phrenology than to physics. For evolutionary biology is a historical science, laden with history's inevitable imponderables. We evolutionary biologists cannot generate a Cretaceous Park to observe exactly what killed the dinosaurs; and, unlike "harder" scientists, we usually cannot resolve issues with a simple experiment, such as adding tube A to tube B and noting the color of the mixture. — Jerry A. Coyne

Dana was lead singer for The Droids, Sweet Valley High's answer to the Rolling Stones. They had a reputation for being pretty wild, but most of it was just conjecture. Not many outsiders knew what went on in the smoky confines of Max Dellon's basement, where they held their practice sessions. — Francine Pascal

If you obey the majority of those on earth, they will lead you astray from God's way. They follow nothing but conjecture. They are only guessing. — Anonymous

[...] if truth be told, evolution hasn't yielded many practical or commercial benefits. Yes, bacteria evolve drug resistance, and yes, we must take countermeasures, but beyond that there is not much to say. Evolution cannot help us predict what new vaccines to manufacture because microbes evolve unpredictably. But hasn't evolution helped guide animal and plant breeding? Not very much. Most improvement in crop plants and animals occurred long before we knew anything about evolution, and came about by people following the genetic principle of 'like begets like'. Even now, as its practitioners admit, the field of quantitative genetics has been of little value in helping improve varieties. Future advances will almost certainly come from transgenics, which is not based on evolution at all.
[review of The Evolving World: Evolution in Everyday Life, Nature 442, 983-984 (31 August 2006)] — Jerry A. Coyne

You should not put too much trust in any unproved conjecture, even if it has been propounded by a great authority, even if it has been propounded by yourself. You should try to prove it or disprove it ... — George Polya

Human knowledge as it actually is and can only ever be is not a revelation of something objectively and timelessly true, an assured grasp of something existing 'out there' independently of ourselves. It is what we have the best grounds at any given time for believing. Because this is what it is, it does indeed provide the best possible basis for our suppositions and actions. But it always remains our belief, our, conjecture, our hypothesis, our theory; and as such, fallible - and also, as such, a creation of the human mind. — Bryan Magee

And while he waited in the castle court,
The voice of Enid, Yniol's daughter, rang
Clear through the open casement of the hall,
Singing; and as the sweet voice of a bird,
Heard by the lander in a lonely isle,
Moves him to think what kind of bird it is
That sings so delicately clear, and make
Conjecture of the plumage and the form;
So the sweet voice of Enid moved Geraint;
And made him like a man abroad at morn
When first the liquid note beloved of men
Comes flying over many a windy wave
To Britain, and in April suddenly
Breaks from a coppice gemmed with green and red,
And he suspends his converse with a friend,
Or it may be the labour of his hands,
To think or say, 'There is the nightingale;'
So fared it with Geraint, who thought and said,
'Here, by God's grace, is the one voice for me. — Alfred Tennyson

That's the vast majority of this social media, all these reviews, all these comments. Your tools have elevated gossip, hearsay and conjecture to the level of valid, mainstream communication. — Dave Eggers

Boldwood, whose unreasoning devotion to Bathsheba could only be characterized as a fond madness which neither time nor circumstance, evil nor good report, could weaken or destroy. This fevered hope had grown up again like a grain of mustard-seed during the quiet which followed the hasty conjecture that Troy was drowned. He nourished it fearfully, and almost shunned the contemplation of it in earnest, lest facts should reveal the wildness of the dream. Bathsheba having at last been persuaded — Thomas Hardy

The mind revels in conjecture. Where information is lacking, it will gladly fill in the gaps. — James Geary

The extraordinary fact is that the first idea I had which motivated me, that worked, is conjecture, a mathematical idea which may or may not be true. And that idea is still unproven. It is the foundation, what started me and what everybody failed to **** prove has so far defeated the greatest efforts by experts to be proven. — Benoit Mandelbrot

Reality was a makeshift prop, an amalgamation of agreed-upon conjecture, a consensus of self-limiting parameters and paradigms made palatable by endless speculation fueled by madness and hope and no mean amount of good dope. — Laird Barron

History is conjecture raised to the level of an art. — Marty Rubin

Experience, already reduced to a group of impressions, is ringed round for each one of us by that thick wall of personality through which no real voice has ever pierced on its way to us, or from us to that which we can only conjecture to be without. — Walter Pater

Such self-transformation is the most difficult and dangerous challenge to the imagination, and it is the most rewarding. Meeting it is only possible for the person whose mind is open to contradictions and well-practiced in free conjecture. — Robert Grudin

For several weeks, I have been the subject of leaked stories, conjecture, and false attacks about a land exchange. None of them bear any resemblance to the truth, including the rumor that I am planning on resigning. — Rick Renzi

To die for an idea is to set a rather high price upon conjecture. — Anatole France

I think everybody handles things very differently and you can conjecture, but until you're put in that situation, you really don't know. — Laura Linney

Mathematics is the music of reason. To do mathematics is to engage in an act of discovery and conjecture, intuition and inspiration; to be in a state of confusion - not because it makes no sense to you, but because you gave it sense and you still don't understand what your creation is up to; to have a break-through idea; to be frustrated as an artist; to be awed and overwhelmed by an almost painful beauty; to be alive, damn it. — Paul Lockhart

The entire annals of Observation probably do not elsewhere exhibit so extraordinary a verification of any theoretical conjecture adventured on by the human spirit! — John Pringle Nichol

The classes of problems which are respectively known and not
known to have good algorithms are of great theoretical interest. [ ... ]
I conjecture that there is no good algorithm for the traveling
salesman problem. My reasons are the same as for any mathematical
conjecture: (1) It is a legitimate mathematical possibility, and
(2) I do not know. — Jack Edmonds

I'm always looking for evidence to support my conjecture that celebrity in Hollywood is sort of like a Joel Peter Witkin photograph: It looks like a big lush banquet table filled with abundance and cornucopias, and then if you look at it closer you see that all the fruit is made of wax and that entree in the middle of the table is actually a dead baby. — Cintra Wilson

Do not be so quick to accept as truth what is only conjecture. — Terry Brooks

To explain all nature is too difficult a task for any one man or even for any one age. Tis much better to do a little with certainty & leave the rest for others that come after than to explain all things by conjecture without making sure of any thing. — Isaac Newton

But there are times when men have serious thoughts, and it is at such times, when they begin to think, that they begin to doubt the truth of the Christian religion; and well they may, for it is too fanciful and too full of conjecture, inconsistency, improbability and irrationality, to afford consolation to the thoughtful man. His reason revolts against his creed. He sees that none of its articles are proved, or can be proved. — Thomas Paine

This, the idea of relationships bit, was all conjecture on her part. She herself felt too young to try to figure out her own life, let alone someone else's life near hers, and so she had never even sought out companionship of that type. Jackie thought about dating from time to time in the distant way a person thinks about eventually becoming famous or owning a castle or growing ram's horns. They're all achievable, realistic goals, but by turning objectives into mere fantasies, she never had to go through the trouble of achieving or maintaining them. — Joseph Fink

A satirist, often in danger himself, has the bravery of knowing that to withhold wit's conjecture is to endanger the species. — Penelope Gilliatt

There is no law, there is only conjecture. The Progressive ethos changes the law's meaning according to fad and fashion. — A.E. Samaan

Ourselves are cosmic and capacious beyond conjecture, and to experience some notion of the planetary perspective is the richest income from travelling. It takes all to inform and educate all. Sallies forth from our cramped firesides into other homes, other hearts, are wonderfully wholesome and enlarging. Travel opens prospects on all sides, widens our horizon, liberates the mind from geographical and conventional limitations, from local prejudices and national, showing the globe in its differing climates, zones, and latitudes of intelligence. — Amos Bronson Alcott

What song the Syrens sang, or what name Achilles assumed when he hid himself among women, though puzzling questions, are not beyond all conjecture. — Thomas Browne

So in this case, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering' - then you should abandon them. — Gautama Buddha

Whether a law be void for its repugnancy to the Constitution, is, at all times, a question of much delicacy, which out seldom, if ever, to be decided in the affirmative, in doubtful case ... But it is not on slight implication and vague conjecture that the legislature is to be pronounced to have transcended its powers, and its acts to be considered as void. The opposition between the Constitution and the law should be such that the judge feels a clear and strong conviction of their incompatibility with each other. — John Marshall

As with most of the legends surrounding the Templars, some of the conjecture about the fate of individuals seems logical, while other suggestions appear to be rather implausible and fabricated for an audience hungry for mysteries and conspiracy theories. — Susie Hodge

The rules of scientific investigation always require us, when we enter the domains of conjecture, to adopt that hypothesis by which the greatest number of known facts and phenomena may be reconciled. — Matthew Fontaine Maury

To believe straight away is foolishness, to believe after having seen clearly is good sense. That is the Buddhist policy in belief; not to believe stupidly, or to rely only on people, textbooks, conjecture, reasoning, or whatever the majority believes, but rather to believe what we see clearly for ourselves to be the case. This is how it is in Buddhism. — Buddhadasa

We are suffering from a plethora of surmise, conjecture, and hypothesis. — Arthur Conan Doyle

There may be a soul of the world, there may be ... a psychical side, of which we are not aware, to every atom in the universe, and the psychical side, like the moon, may show us ever but the one face, the other forever in the shadow; but, at best, this is only a conjecture, it presents no solid foundation upon which to rest a theory. — John Grier Hibben

And what of our own universe? The newest conjecture is that all that we experience - from the tiniest vibrating string of energy to that massive galaxy spinning around a maelstrom of reality-ripping black holes - may be nothing more than a hologram, a three-dimensional illusion that, in fact, we may all be living in a created simulation. Could that be possible? Could Plato have been right all along: that we are blind to the true reality around us, that all we know is nothing more than the flickering shadow on a cave wall? — James Rollins

I conjecture that the origin of life and the origin of problems coincide. — Karl R. Popper

The atheist risk everything for the present and the future, on the basis of a belief that we are uncaused by any intelligent being. We just happen to be here. That one is willing to live and die in that belief is a very high price to pay for conjecture. — Ravi Zacharias

Conjecture as to things useful, is good; but conjecture as to what it would be useless to know, is very idle. — Samuel Johnson

Rumor had it that Professor Jerkwad had a history of holding classes in bars and using the school's senior class as harvesting grounds for a long string of wives who never seemed to stay married to him past age twenty-eight. Rumor also had it that a few years later he was canned from his job mid some rather unpleasant allegations, but we journalists can't succumb to rumor and conjecture when nonspecific innuendo is so much more titillating. — June Casagrande

They who have just ideas, and express them in suitable language, would need to use no long discourse to refute the errors of empty conjecture. — Augustine Of Hippo

The importance of the romantic element does not rest upon conjecture. Pleasing testimonies abound. Hannah More traced her earliest impressions of virtue to works of fiction; and Adam Clarke gives a list of tales that won his boyish admiration. Books of entertainment led him to believe in a spiritual world; and he felt sure of having been a coward, but for romances. He declared that he had learned more of his duty to God, his neighbor and himself from Robinson Crusoe than from all the books, except the Bible, that were known to his youth. — Robert Aris Willmott

Feathers," he says.

They ask this question at least once a week. He gives the same answer. Even over such a short time - two months, three? He's lost count - they've accumulated a stock of lore, of conjecture about him: Snowman was once a bird but he's forgotten how to fly and the rest of his feathers fell out, and so he is cold and he needs a second skin, and he has to wrap himself up. No: he's cold because he eats fish, and fish are cold. No: he wraps himself up because he's missing his man thing, and he doesn't want us to see. That's why he won't go swimming. Snowman has wrinkles because he once lived underwater and it wrinkled up his skin. Snowman is sad because the others like him flew away over the sea, and now he is all alone. — Margaret Atwood

When we seek a textbook case for the proper operation of science, the correction of certain error offers far more promise than the establishment of probable truth. Confirmed hunches, of course, are more upbeat than discredited hypotheses. Since the worst traditions of "popular" writing falsely equate instruction with sweetness and light, our promotional literature abounds with insipid tales in the heroic mode, although tough stories of disappointment and loss give deeper insight into a methodology that the celebrated philosopher Karl Popper once labeled as "conjecture and refutation. — Stephen Jay Gould

Nothing is more wretched than a man who traverses everything in a round, and pries into things beneath the earth, as the poet says, and seeks by conjecture what is in the minds of his neighbours, without perceiving that it is sufficient to attend to the daemon within him, — Various

Occasionally, I get a letter from someone who is in "contact" with extraterrestrials. I am invited to "ask them anything." And so over the years I've prepared a little list of questions. The extraterrestrials are very advanced, remember. So I ask things like, "Please provide a short proof of Fermat's Last Theorem." Or the Goldbach Conjecture. And then I have to explain what these are, because extraterrestrials will not call it Fermat's Last Theorem. So I write out the simple equation with the exponents. I never get an answer. On the other hand, if I ask something like "Should we be good?" I almost always get an answer. — Carl Sagan

The dream shows the inner truth and reality of the patient as it really is: not as I conjecture it to be, and not as he would like it to be, but as it is. — C. G. Jung

A biographer has to decide between slowing to a halt in a bog of conflicting possibilities or striding boldly across by a causeway of conjecture. I choose the second course and, without stepping aside to discuss all the alternatives, tell the story as I see it. Paul's next eighteen months unfolded somewhat as follows, though the tone of assurance in my narrative must not disguise that some of its conclusions are tentative and disputable. The — John Charles Pollock

When Euler died, he simply said I am finished and collapsed, to which someone in the audience muttered darkly" Another conjecture of Euler is proved — Paul Erdos

The art of discovering the causes of phenomena, or true hypothesis, is like the art of decyphering, in which an ingenious conjecture greatly shortens the road. — Gottfried Leibniz

And I think that at a certain point, after all the time and all the conjecture and everything that had kind of gone on surrounding this show, I think that Mitch just felt like it was time to let it go. It was best for the show. — Will Arnett

We were none of us particularly drunk. But then again, none of us were particularly sober either. Our exact positioning between these two points is a matter of pointless conjecture, and I will waste no time on it. — Patrick Rothfuss

I think now I'm being taken a little more seriously. That's pure conjecture on my part. — Tom Wopat

I think it actually makes more sense for a new audience than the old show did because we're focusing on one character at a time. It's all conjecture why somebody didn't watch, but one of the theories was that there was just so much information, even in the trailers and promos, of all these different people. — Mitchell Hurwitz

Their origin is commonly unknown; for the practice often continues when the cause has ceased, and concerning superstitious ceremonies it is in vain to conjecture; for what reason did not dictate, reason cannot explain. — Samuel Johnson

The wisdom of God exceeds that of the wisest man, more than his wisdom exceeds that of a child. If a child were to conjecture how an army is to be formed in the day of battle
how a city is to be fortified, or a state governed
what chance has he to guess right? As little chance has the wisest man when he pretends to conjecture how the planets move in their courses, how the sea ebbs and flows, and how our minds act upon our bodies. — Thomas Reid

We have to learn again that science without contact with experiments is an enterprise which is likely to go completely astray into imaginary conjecture. — Hannes Alfven

Each dark conjecture came and for a moment settled like a vulture on Bond's shoulder and croaked into his ear that he had been a blind fool. — Ian Fleming

Who am I to say that these things might not be forever? Who is Peter Van Houten to assert as fact the conjecture that our labor is temporary? All I know of heaven and all I know of death is in this park; an elegant universe in ceaseless motion, teeming with ruined ruins and screaming children. — John Green

If a man dreams that he has committed a sin before which the sun hid his face, it is often safe to conjecture that, in sheer forgetfulness, he wore a red tie, or brown boots with evening dress. — Arthur Machen

The Temple of Diana is in the vicinity of the fountain, which has given rise to the conjecture that it originally constituted a portion of the ancient baths. — Marguerite Gardiner

In the first day of the Soviet Army's arrival, I and the other comrades were isolated and then found ourselves here, not knowing anything ... I can only conjecture what could have happened. — Alexander Dubcek

Memory retains some things and discards others. I remember every detail of some scenes from my childhood and adolescence, by no means the most important ones. I remember some people and have totally forgotten others. Memory is like the headlights of a car at night, which fall now on a tree, now on a hut, now on a man. People (usually writers) who tell the story of their lives as a continuous and detailed whole generally fill in the gaps with conjecture; it is hard to tell where genuine reminiscence ends and the novel begins. — Ilya Ehrenburg

No state sorrier than that of the man who keeps up a continual round, and pries into "the secrets of the nether world," as saith the poet, and is curious in conjecture of what is in his
neighbour's heart. — Marcus Aurelius

A private man has always the liberty (because thought is free) to believe or not believe in his heart those acts that have been given out for miracles, according as he shall see what benefits can accrue by men's belief, to those that pretend, or countenance them, and thereby conjecture whether they be miracles or lies. — Thomas Hobbes

Belief is at best an educated, informed conjecture about Reality. — Steve Hagen

While the scientist, on the one hand, is concerned with giving a faithful description of facts, on the other, he has the equally important task of construing them in relation to some explanatory conjecture. Similarly the historian has a double duty: both of reporting the past as nearly as possible as it passed or was lived through by men at the time (without doctoring up events to fit later developments or some more "enlightened reading" of them); and second, of interpreting their import in the light of a present hypothesis. — Marie Taylor Collins Swabey

His emotion on entering the room, in seeing her altered looks, and in receiving the pale hand which she immediately held out to him, was such as, in Elinor's conjecture, must arise from something more than his affection for Marianne, or the consciousness of its being known to others; and she soon discovered, in his melancholy eye and varying complexion as he looked at her sister, the probable recurrence of many past scenes of misery to his mind, brought back by that resemblance between Marianne and Eliza already acknowledged, and now strengthened by the hollow eye, the sickly skin, the posture of reclining weakness; and the warm acknowledgment of peculiar obligation. — Jane Austen

A felicitous but unproved conjecture may be of much more consequence for mathematics than the proof of many a respectable theorem. — Atle Selberg

The world has arisen in some way or another. How it originated is the great question, and Darwin's theory, like all other attempts, to explain the origin of life, is thus far merely conjectural. I believe he has not even made the best conjecture possible in the present state of our knowledge. — Louis Agassiz

Nothing is known in our profession by guess; and I do not believe, that from the first dawn of medical science to the present moment, a single correct idea has ever emanated from conjecture: it is right therefore, that those who are studying their profession should be aware that there is no short road to knowledge; and that observation on the diseased living, examination of the dead, and experiments upon living animals, are the only sources of true knowledge; and that inductions from these are the sole bases of legitimate theory. — Astley Cooper

The agnostic does not simply say, "l do not know." He goes another step, and he says, with great emphasis, that you do not know. He insists that you are trading on the ignorance of others, and on the fear of others. He is not satisfied with saying that you do not know,
he demonstrates that you do not know, and he drives you from the field of fact
he drives you from the realm of reason
he drives you from the light, into the darkness of conjecture
into the world of dreams and shadows, and he compels you to say, at last, that your faith has no foundation in fact. — Robert G. Ingersoll

Physiognomy is not a guide that has been given us by which to judge of the character of men: it may only serve us for conjecture.
[Fr., La physionomie n'est pas une regle qui nous soit donnee pour juger des hommes; elle nous peut servir de conjecture.] — Jean De La Bruyere

Mathematicians use intuition, conjecture and guesswork all the time except when they are in the classroom. — Joseph Warren

Having always observed that most of them who constantly took in the weekly Bills of Mortality made little other use of them than to look at the foot how the burials increased or decreased, and among the Casualties what had happened, rare and extraordinary, in the week current; so as they might take the same as a Text to talk upon in the next company, and withal in the Plague-time, how the Sickness increased or decreased, that the Rich might judg of the necessity of their removal, and Trades-men might conjecture what doings they were likely to have in their respective dealings. — John Graunt

The world, and whatever that be which we call the heavens, by the vault of which all things are enclosed, we must conceive to be a deity, to be eternal, without bounds, neither created nor subject at any time to destruction. To inquire what is beyond it is no concern of man; nor can the human mind form any conjecture concerning it. — Pliny The Elder

A mathematician experiments, amasses information, makes a conjecture, finds out that it does not work, gets confused and then tries to recover. A good mathematician eventually does so - and proves a theorem. — Steven G. Krantz

The appearance and retirement of actors are the great events of the theatrical world; and their first performances fill the pit with conjecture and prognostication, as the first actions of a new monarch agitate nations with hope and fear. — Samuel Johnson

When the animals entered the Ark in pairs, one may imagine that allied species made much private remark on each other, and were tempted to think that so many forms feeding on the same store of fodder were eminently superfluous, as tending to diminish the rations ...
The same sort of temptation befell the Christian Carnivora who formed Peter Featherstone's funeral procession; most of them having their minds bent on a limited store which each would have liked to get the most of. The long-recognized blood-relations and connexions by marriage made already a goodly number, which, multiplied by possibilities, presented a fine range for jealous conjecture and pathetic hopefulness. — George Eliot

That was the way with Casaubon's hard intellectual labours. Their most characteristic result was not the 'Key to all Mythologies', but a morbid consciousness that others did not give him the place which he had not demonstrably merited - a perpetual suspicious conjecture that the views entertained of him were not to his advantage - a melancholy absence of passion in his efforts at achievement, and a passionate resistance to the confession that he had achieved nothing.
Thus his intellectual ambition which seemed to others to have absorbed and dried him, was really no security against wounds — George Eliot

I have been speculating last night what makes a man a discoverer of undiscovered things. As far as I can conjecture the art consists in habitually searching for the causes and meaning of everything which occurs. — Charles Darwin

Truly it is said, that knowledge is chief of all things, my son. It allows us to see clearly what we may achieve. Conjecture is no substitute for fact. — Richard Masefield

The ocean is the last frontier of human empirical knowledge; even the contours on that eighth-grader's globe are the product of a mix of scientific measurement, inference and conjecture. — Alan Huffman

If a man in order to shoot a hare, were to discharge thousands of guns on a great moor in all possible directions; if in order to get into a locked room, he were to buy ten thousand casual keys, and try them all; if, in order to have a house, he were to build a town, and leave all the other houses to wind and weather - assuredly no one would call such proceedings purposeful and still less would anyone conjecture behind these proceedings a higher wisdom, unrevealed reasons, and superior prudence. — J. W. N. Sullivan

Being human and investigating the affairs of the gods is an extreme version of being tone-deaf and talking about music, or having never served in the army and talking about warfare: we resemble amateurs trying to use arguments from probability based on opinions and conjecture to unearth the ideas of experts. Given — Plutarch
