Speculative Quotes & Sayings

The true secret of success in the investment and speculative world is not so much which good securities to buy, but rather which investments to avoid. — Morton Shulman

There are two distinctive peculiarities by reference to which we characterize the soul (1) local movement and (2) thinking, discriminating, and perceiving. Thinking both speculative and practical is regarded as akin to a form of perceiving; for in the one as well as the other the soul discriminates and is cognizant of something which is. — Aristotle.

I fear that, in the end, the famous debate among materialists, idealists, and dualists amounts to a merely verbal dispute that is more a matter for the linguist than for the speculative philosopher. — Moses Mendelssohn

Oh shit, oh shit, stupid shower present!"
Now she did pull her hair as she made the dash to her office.
Roarke sat in her visitor's chair, comfortably involved with his PPC. He glanced up, let loose a regretful sigh. "You changed. And I didn't have any time to ogle you in uniform."
"I have to go shopping!"
Staring at her, Roarke pressed his fingertips to his temple. "I'm sorry, I believe I must have had a small stroke. What did you say?"
"This isn't funny." She bent down, gripped him by the lapels. "I forgot to get a thing for the thing, and I don't even know what the thing is supposed to be. Now I have to go out and hunt something down. Except - " Her eyes went from slightly mad to speculative. "We have all kinds of things around the house. Couldn't I just wrap something up and - "
"No."
"Crap! — J.D. Robb

Young earth creationists try to force modern science into a literal reading of Genesis 1. Day-age theorists try to fit Genesis 1 into modern science. Proponents of the restoration view try to have their cake and eat it too by inserting a speculative gap between verses 1 and 2 of this chapter. All three views are fundamentally misguided and are rooted in contradictory opinions about the meaning and significance of various words and phrases in Genesis 1 (e.g., "day," "formless void"). None of them have seriously considered the more fundamental question concerning the kind of literature we are dealing with in Genesis 1. More — Gregory A. Boyd

The Freedom of Information Act should be administered with a clear presumption: In the face of doubt, openness prevails. The Government should not keep information confidential merely because public officials might be embarrassed by disclosure, because errors and failures might be revealed, or because of speculative or abstract fears. — Barack Obama

By the end of Barber's talk, this event she's celebrating sounds like a product of the imagination of some master of speculative fiction like Philip K. Dick or Ray Bradbury - a mad dystopia in which feminist dreams have led to a forest full of separate clearings in which more and more women keep to smaller and smaller groups for fear of encountering difference. — Bruce Bawer

For instance, in one corner of the Eastern Galactic Arm lies the large forest planet Oglaroon, the entire "intelligent" population of which lives permanently in one fairly small and crowded nut tree. In which tree they are born, live, fall in love, carve tiny speculative articles in the bark on the meaning of life, the futility of death and the importance of birth control, fight a few extremely minor wars and eventually die strapped to the underside of some of the less accessible outer branches. In — Douglas Adams

The period of financial distress is a gradual decline after the peak of a speculative bubble that precedes the final and massive panic and crash, driven by the insiders having exited but the sucker outsiders hanging on hoping for a revivial, but finally giving up in the final collapse. — Charles P. Kindleberger

As the wind continued to howl and groan through her decaying body, she began to sing her story. — Ken Liu

At Tara in this fateful hour,
I place all Heaven with its power,
And the sun with its brightness,
And the snow with its whiteness,
And the fire with all the strength it hath,
And the lightning with its rapid wrath,
And the winds with their swiftness along their path,
And the sea with its deepness,
And the rocks with their steepness,
And the earth with its starkness:
All these I place,
By God's almighty help and grace
Between myself and the powers of darkness! — Madeleine L'Engle

Like much of the identitarian Left, feminists want to replace old etiquette rules with a new system of politically-driven language policing, controlled by them and predicated on nebulous hurt feelings and speculative "harm." Having long overturned the hectoring, socially-conservative establishment, they now want to assume its place. — Milo Yiannopoulos

There was more than one way to think about Mike Burry's purchase of a billion dollars in credit default swaps. The first was as a simple, even innocent, insurance contract. Burry made his semiannual premium payments and, in return, received protection against the default of a billion dollars' worth of bonds. He'd either be paid zero, if the triple-B-rated bonds he'd insured proved good, or a billion dollars, if those triple-B-rated bonds went bad. But of course Mike Burry didn't own any triple-B-rated subprime mortgage bonds, or anything like them. He had no property to "insure" it was as if he had bought fire insurance on some slum with a history of burning down. To him, as to Steve Eisman, a credit default swap wasn't insurance at all but an outright speculative bet against the market - and this was the second way to think about it. — Michael Lewis

He's back in Maine now.She did say he badgered her with questions. Of course, she didn't have the answer until she spoke to me and found out you were here." Gennie frowned at the sea and said nothing. "She wondered if you were following Macintosh in the papers. It took me over two hours to figure why she would have asked that.
Gennie turned back with a speculative look which Serena met blandly. "Perhaps I'm not following you," she said, automatically guarding Grant's secret.
Serena took the pot the waiter placed on the table. "Coffee,Veronica?"
Gennie let out an admiring laugh and nodded her head. "You're very quick, Rena."
"I love puzzles," she corrected, "and the pieces were all there. — Nora Roberts

Closed head trauma is about as much fun as nude paintballing. — D.C. Farmer

One day, I decided to be an island. I took off my clothes and walked into the sea, then floated there, bobbing along with the tide, suspended by my inflatable tube and water wings. — Ng Yi-Sheng

I will put my hook in thy nose and my bridle in thy lips, and I will turn thee back by the way which thou camest. 'Destroyer' thou hast embraced, and Abaddon shalt thou be. From the furnace of the Kiln wast thou taken and to the furnace of Hell shalt thou return. — Donovan M. Neal

If there's another writer, like Ross McDonald or Raymond Chandler, and all they're writing are mysteries, they won't be accepted," he said. "And that's problematic. A lot of so-called literary novels are just not very good. They're not well-written, they're not well-thought-out. They have pyrotechnics of intelligence.
"On the other hand, some of the best writers and speculative ideas are in science-fiction. The science-fiction genre is completely, completely segregated. And these people are writing good stuff. They're writing about where you're going, which means they're talking about where you are. — Walter Mosley

In practical life we are compelled to follow what is most probable ; in speculative thought we are compelled to follow truth. — Baruch Spinoza

The Hum-bird paused, a long needle sliding out of the hole in its beak. It bent quickly, poking the needle into Scarlett's face. Its head popped back up and then repeated the motion in three more spots on the Jordan's face before hopping to the other side and starting over.

It hopped back and forth a few more times, pausing now and then with its injector, plumping skin and filling the fine lines in Scarlett's face. After examining its works, the needle withdrew and another one protruded, glistening pink in the dimmed light. This time the Hum-bird hopped around, paralyzing any damaging nerve clusters that over time would be bound to cause wrinkles in the skin. — April Adams

Evolution is a bankrupt speculative philosophy, not a scientific fact. Only a spiritually bankrupt society could ever believe it. Only atheists could accept this Satanic theory. — Jimmy Swaggart

I shall endeavour still further to prosecute this inquiry, an inquiry I trust not merely speculative, but of sufficient moment to inspire the pleasing hope of its becoming essentially beneficial to mankind. — Edward Jenner

If you write thrillers or mysteries or horror fiction or quote-unquote speculative fiction, men might read you, and the 'Times' might notice you. — Jennifer Weiner

At long as a stock is acting right, and the market is right, do not be in a hurry to take profits. One should never permit speculative ventures to run into investments. — Jesse Lauriston Livermore

We shall do well ever to remember, that Christianity is not a mere speculative theory, that is to inform the mind; but a great practical lesson, to renew the heart, and to bring us back to the state from whence we are fallen. — Charles Simeon

Because there wasn't anything else to do, he settled at the kitchen table
with a bottle of mead and nearly emptied it. The anesthetic effect he hoped for hadn't happened, though. At least not yet. — Ann Gimpel

The campaign website was funded by Armistead, and he personally authored the content. He was determined that the campaign's values and goals would fit on one page. The website developer, who was experienced with political campaigns, was opposed to this. He lobbied for detailed policy statements and explanations, which was the conventional approach. But Armistead disagreed. The website developer thus learned that day that core principles were more important than thousands of words of speculative verbiage. — Rodney Page

Those who think of metaphysics as the most unconstrained or speculative of disciplines are misinformed; compared with cosmology, metaphysics is pedestrian and unimaginative. - Stephen Toulmin — Sean Carroll

I'll tell you an explanation that I find commonly overrated and speculative in the extreme: the idea that things that succeed in popular culture do that because they hit the temper of the times. — Cass Sunstein

I did precisely the wrong thing. The cotton showed me a loss and I kept it. The wheat showed me a profit and I sold it out. Of all the speculative blunders there are few greater than trying to average a losing game. Always sell what shows you a loss and keep what shows you a profit. — Jesse Lauriston Livermore

In the stock market the more elaborate and abstruse the mathematics the more uncertain and speculative the conclusion we draw therefrom ... . — Michael Lewis

With uncertainty in oil markets, a buildup of speculative pressures and the large U.S. current account deficit, there is a real possibility that Paulson's crisis-management skills will be tested. — Lawrence Summers

Tied up a lot of women, have you?" He raised one eyebrow, whatever that meant. "A bit odd, are you?" She was being sarcastic, trying to taunt him into a sense of guilt. While perhaps bursting any bubble in herself of misguided, soft-hearted concern for a man with sad eyes and complicated wealth. Though his sexual inclinations were perhaps not the wisest of barbs to do either. He looked down at her, speculative.
"Difficult to say." He actually answered the question seriously. "Legally? Decidedly. But then British laws on the subject are so guilt-ridden I'm surprised we've propagated as a race." He mad a small, grim smile. "How delightful we're having this conversation. And what is it you like? — Judith Ivory

This doctrine of necessity in universality means that there is an essence to the universe which forbids relationships beyond itself, as a violation of its rationality. Speculative philosophy seeks that essence. — Alfred North Whitehead

Seek first the Kingdom of God: that is, the first order of business is to transform one's own inner life, not the accumulation of external trappings of speculative knowledge. — John D. Caputo

They live inside of what is essentially one huge wearable. Everyone connected to everyone even when they shit. — Brenda Cooper

In my imagination, the Editor meditated in a mountain-cave, espoused the rules of grammar, and frowned upon speculative fiction. — Josh Malerman

I mean, that was the code, wasn't it? Single girls and taken guys weren't allowed to be friends. The leash always got in the way. — Carrie Butler

Speculative fiction both requires and rewards an open mind. — Steven Poore

Surely not without reason, when pirates, highwaymen, and other varieties of the extensive genus Marauder, are the only beau ideal of the active, as splenetic and railing misanthropy is of the speculative energy. — Thomas Love Peacock

I think one has to understand, not as a theory, not as a speculative, entertaining concept, but rather as an actual fact - that we are the world and the world is us. The world is each one of us; to feel that, to be really committed to it and to nothing else, brings about a feeling of great responsibility and an action that must not be fragmentary, but whole. — Jiddu Krishnamurti

In a way, I feel I have enough tools and knowledge now that when I build it has a very specific agency that's very conscious. It's no longer speculative; it's really constructed. I'm very interested in how that consciousness, about how I am producing, is working within different conditions. It's like growing up. — David Adjaye

Even in forgetting there is an aspect of recollection, a faded few moments of wispy consciousness clung like webs in high-vaulted chambers, moving ever so lightly with the draft. — Jeffrey Panzer

No, no, it's not in books at all you're looking for! Take it where you can find it, in old phonograph records, old motion pictures, and in old friends; look for it in nature and look for it in yourself. Books were only one type of receptacle where we stored a lot of things we were afraid we might forget. There is nothing magical in them, at all. The magic is only in what books say, how they stitched the patches of the universe together into on garment for us. — Ray Bradbury

An early fascination with higher mathematics at the university level blossomed into speculative thinking that could provide a basis for dealing with economic issues. — Lawrence R. Klein

First, there is a large body of empirical evidence on the predictive accuracy of speculative markets, on everything from horse-racing to elections to invasions. "Put your money where your mouth is" turns out to be a great way to get the well informed to reveal what they know, and the poorly informed to quiet down. No system is perfect, but betting markets outperform other methods of prediction in a wide variety of circumstances. The PAM was inspired not by ivory tower theorizing, but by the proven success of betting markets in other areas. — Bryan Caplan

As a writer of fiction who deals with technology, I necessarily deal with the history of technology and the history of technologically induced social change. I roam up and down it in a kind of special way because I roam down it into history, which is invariably itself a speculative affair. — William Gibson

still the teachings of the philosophers are not the commandments of the gods, but the discoveries of men, who, at the prompting of their own speculative ability, made efforts to discover the hidden laws of nature, and the right and wrong in ethics, and in dialectic what was consequent according to the rules of logic, and what was inconsequent and erroneous. — Augustine Of Hippo

Mathematics is ordinarily considered as producing precise and dependable results; but in the stock market the more elaborate and abstruse the mathematics the more uncertain and speculative are the conclusions we draw there from. Whenever calculus is brought in, or higher algebra, you could take it as a warning that the operator was trying to substitute theory for experience, and usually also to give to speculation the deceptive guise of investment. — Benjamin Graham

All the interests of my reason, speculative as well as practical, combine in the three following questions: 1. What can I know? 2. What ought I to do? 3. What may I hope? — Immanuel Kant

Civic participation depends on creativity, an (aesthetic) knack for reframing experience, and on a corollary freedom to adjust laws and practices in light of ever-new challenges. Without art, citizenship would shrink to compliance, as if society were a closed text. Reading lessons would stop at the factual "what is," rather than continue to the speculative "what if. — Doris Sommer

..."extreme capitalism": the obsessive, uncritical penetration of the concept of the market into every aspect of American life, and the attempt to drive out every other institution, including law, art, culture, public education, Social Security, unions, community, you name it. It is the conflation of markets with populism, with democracy, with diversity, with liberty, and with choice---and so the denial of any form of choice that imposes limits on the market. More than that, it is the elimination of these separate concepts from our political discourse, so that we find ourselves looking to the stock market to fund retirement, college education, health care, and having forgotten that in other wealthy and developed societies these are rights, not the contingent outcomes of speculative games.

James K. Galbraith, Lloyd M. Bentsen Jr. Chair in Government/Business Relations and Professor of Government, University of Texas. — James K. Galbraith

I can think of no series of words that could appear in a piece of naturalistic fiction that could not also appear in the same order in a piece of speculative fiction. I can, however, think of many series of words that, while fine for speculative fiction, would be meaningless as naturalism. Which then is the major and which the subcategory? — Samuel R. Delany

A man full of warm, speculative benevolence may wish his society otherwise constituted than he finds it; but a good patriot, and a true politician, always considers how he shall make the most of the existing materials of his country. — Edmund Burke

It's nice to be nice. — Kurt Vonnegut Jr.

The worst speculative Sceptic ever I knew, was a much better Man than the best superstitious Devotee & Bigot."
"I must inform you, too, that this was the way of thinking of the Antients on this Subject. If a Man made Proffession of Philosophy, whatever his Sect was, they alaways expected to find more Regulaity in his Life and Manners, than in those of ignorant & illiterate. — David Hume

On the far side of the bay was the command station that controlled the door, which was currently semi-open. Rather than the normal closed maw of steel, there was a network of pulsing gold veins crisscrossing the gaping mouth of black - a nitrogen membrane keeping the molecular air contained and pressurized while allowing aircraft to pass through. — April Adams

I shake my head and rub the bridge of my nose. "There's a whole lot more at stake here than just my happiness, so I'll let the doctors do whatever tests they want and answer any questions they have. But after that we save the world. And then we move on, okay? — Kara Swanson

Regardless of religion (or lack thereof), lovers of speculative fiction will swallow up these provocative stories. - Erin O'Riordan, — Tim Lieder

Stock market corrections, although painful at the time, are actually a very healthy part of the whole mechanism, because there are always speculative excesses that develop, particularly during the long bull market. — Ron Chernow

To my surprise, the sensation of query filled my stomach, spreading through to every corner. This was followed by each point of query ending at the same answer. Device Nineteen had responded to the question by coming to the conclusion that oblivion was the end of every path.
Great. My roommate's an emo.>
My stomach reviewed the comment and rumbled queries to various parts of the diamond, but most were returned unanswered because the required systems were not yet online. — J. Cameron McClain

I've loved sci-fi and speculative fiction since I was a kid. It was inevitable I'd try my hand at it at some point. — Rick Yancey

Let us be dreamers, thinkers, speculative philosophers, or as our spouses would have it: Idiots — Douglas Adams

We hear much nowadays as to the speculative ideas of men concerning the condition beyond the grave; but the admission that there is an individual existence beyond the grave, is a declaration that there must have been an individual, intelligent creation before we came here in the flesh. Life beyond the grave postulates a pre-existent state. — James E. Talmage

It has always seemed to me extreme presumptuousness on the part of those who want to make human ability the measure of what nature can and knows how to do, since, when one comes down to it, there is not one effect in nature, no matter how small, that even the most speculative minds can fully understand. — Galileo Galilei

When I stand on my special-issue "Intelligent Investor" ladder and peer out over the frenzied crowd, I see very few others doing the same. Many stocks remain overvalued, and speculative excess - both on the upside and on the downside - is embedded in the frenzy around stocks of all stripes. And yes, I am talking about March 2001, not March 2000. — Michael Burry

With timid curiosity, I asked, what do you mean the old bodies get reused? — Andrew Cormier

He had no longer free energy enough for spontaneous research and speculative thinking, but by the bedside of patients the direct external calls on his judgment and sympathies brought the added impulse needed to draw him out of himself. It was not simply that beneficent harness of routine which enables silly men to live respectably and unhappy men to live calmly - it was a perpetual claim on the immediate fresh application of thought, and on the consideration of another's need and trial. Many of us looking back through life would say that the kindest man we have ever known has been a medical man, or perhaps that surgeon whose fine tact, directed by deeply-informed perception, has come to us in our need with a more sublime beneficence than that of miracle-workers. Some of that twice-blessed mercy was always with Lydgate in his work at the Hospital or in private houses, serving better than any opiate to quiet and sustain him under anxieties and his sense of mental degeneracy. — George Eliot

The true value of the Christian religion rests, not upon speculative views of the Creator, which must necessarily be different in each individual, according to the extent of the knowledge of the finite being, who employs his own feeble powers in contemplating the infinite:;: but it rests upon those doctrines of kindness and benevolence which that religion claims and enforces, not merely in favour of man himself but of every creature susceptible of pain or of happiness. — Charles Babbage

There's more to research than just looking up facts. Eventually, you have to make subjective calls. If you're writing a science fiction novel, there's probably some speculative technology in it. You'll have to decide how to project existing technology forward in a plausible way. — Andy Weir

Some of the History Channel's documentaries involve docudrama segments and are highly speculative - but there seems, on the part of the producers, to be a real determination to get at the history behind our past - not the sex, which is left to drama shows and entertainment channels. — Nigel Hamilton

Experimental science is a craft and an art, and part of the art is knowing when to end a fruitless experiment. There is a danger of becoming obsessed with a fruitless experiment even if it goes nowhere. It is always a good plan for a speculative experimenter to have two experiments going, or at least one going and one being built. — Martin Lewis Perl

Good fantasy fiction: ... explores real human conditions through fantastic metaphors which universalize the characters' individual experiences to speak personally to us all. — Laura Resnick

This truth may be handled either sinfully or profitably; sinfully as when it is treated on only to satisfy curiosity, and to keep up a mere barren speculative dispute ... This point of election ... is not to be agitated in a verbal and contentious way, but in a saving way, to make us tremble and to set us upon a more diligent and close striving with God in prayer, and all other duties. — Anthony Burgess

The time approaches
That will with due decision make us know
What we shall say we have and what we owe.
Thoughts speculative their unsure hopes relate,
But certain issue strokes must arbitrate;
Towards which, advance the war.
They exit marching. — William Shakespeare

In practical matters the end is not mere speculative knowledge of what is to be done, but rather the doing of it. It is not enough to know about Virtue, then, but we must endeavor to possess it, and to use it, or to take any other steps that may make. — Aristotle.

Can you catch the expression of the Sperm Whale's there? It is the same he died with, only some of the longer wrinkles in the forehead seem now faded away. I think his broad brow to be full of a prairie-like placidity, born of a speculative indifference as to death. But mark the other head's [Right Whale] expression. See that amazing lower lip, pressed by accident against the vessel's side, so as firmly to embrace the jaw. Does not this whole head seem to speak of an enormous practical resolution in facing death? This Right Whale I take to have been a Stoic; the Sperm Whale, a Platonian, who might have taken up Spinoza in his latter years. — Herman Melville

Will posterity believe that, while the Press has swarmed with inflammatory productions that tend to prove the blessing of theoretical confusion and speculative licentiousness, not one writer of talent has been employed to refute and confound the fashionable doctrines, nor the least care taken to disseminate works of another complexion. — Arthur Young

Scientific research is compounded of ... empirical procedures, general speculative ideas, and mathematical or abstract reasoning. — James Bryant Conant

It had the strangest effect on my internal visualizations." She stared at the hypospray with speculative respect. "I may try it on purpose someday." I want to be there if you do. Miles had a sudden exciting vision of using the drug to augment his own insights - instant brains! - then remembered to his extreme disappointment that fast-penta didn't work like that on him. Riva — Lois McMaster Bujold

Hmph. Even the animals deserted me.
I'd have deserted me, too, a different inner voice inserted dryly. The way I
banged around in here wanting to kill something - anything - if only it would bring Aislinn back to me. Fionn understood at a level beyond reckoning that if he ever laid eyes on Travis again, the Hunter would be dead before he saw what hit him. — Ann Gimpel

I make films but I am trained as a designer. I come from this series of designers called critical designers, speculative designers. — Nelly Ben Hayoun

Seventh bearer of the cursed name Akiva." Here he paused, speculative. "No Misbegotten ever bore that name to manhood before you. Did you know that? Old Byon the steward, he gave it out of spite. Wanted your mother to beg him not to. Any other woman in the harem would have, but not Festival. 'Scribble whatever you like on your list, old man,' she told him. 'My son will not be tangled in your feeble fates.' — Laini Taylor

A major boom in real stock prices in the U.S. after 'Black Tuesday' brought them halfway back to 1929 levels by 1930. This was followed by a second crash, another boom from 1932 to 1937, and a third crash. Speculative bubbles do not end like a short story, novel, or play. There is no final denouement that brings all the strands of a narrative into an impressive final conclusion. In the real world, we never know when the story is over. — Robert J. Shiller

Speculators are obsessed with predicting: guessing the direction of stock prices. Every morning on cable television, every afternoon on the stock market report, every weekend in Barron's, every week in dozens of market newsletters, and whenever business people get together. In reality, no one knows what the market will do; trying to predict it is a waste of time, and investing based upon that prediction is a purely speculative undertaking. — Seth Klarman

A wonderful area for speculative academic work is the unknowable. These days religious subjects are in disfavor, but there are still plenty of good topics. The nature of consciousness, the workings of the brain, the origin of aggression, the origin of language, the origin of life on earth, SETI and life on other worlds ... this is all great stuff. Wonderful stuff. You can argue it interminably. But it can't be contradicted, because nobody knows the answer to any of these topics. — Michael Crichton

In actions of enthusiasm, this drawback appears: but in those lower activities, which have no higher aim than to make us more comfortable and more cowardly, in actions of cunning, actions that steal and lie, actions that divorce the speculative from the practical faculty, and put a ban on reason and sentiment, there is nothing else but drawback and negation. — Ralph Waldo Emerson

Speculative joy, the joy derived from being right and being rewarded, may well be similar to the rush felt by a winning gambler. — Michael Steinhardt

Stock prices are likely to be among the prices that are relatively vulnerable to purely social movements because there is no accepted theory by which to understand the worth of stocks ... investors have no model or at best a very incomplete model of behavior of prices, dividend, or earnings, of speculative assets. — Robert J. Shiller

Faith is not a blind thing; for faith begins with knowledge. It is not a speculative thing; for faith believes facts of which it is sure. It is not an unpractical, dreamy thing; for faith trusts, and stakes its destiny upon the truth of revelation. — Charles Haddon Spurgeon

A maxim is a conclusion upon observation of matters of fact, and is merely speculative; a "principle" carries knowledge within itself, and is prospective. — Samuel Taylor Coleridge

Currency speculation-over a trillion dollars a day-is a tax-free activity. The notion of a tax on "day trades" or other speculative swaps was revived in recent years, but has been studiously ignored by all our purveyors of conventional economic wisdom. That is because we have been persuaded, against logic, and moral sense, that the institution that most needs our support these days is not society, nor the human community, but the global corporation. — Eric Kierans

The Jeep windshield was doing its damnedest to stay clear, but the amount of water flowing over it threatened to overwhelm the ionizer. — Julian May

Americans had built themselves a world of speculative pipe dreams. That world was inhabited, not by people who had to be convinced, but by people who sought excuses for believing. — John Kenneth Galbraith

... the distance is commonly very great between actual performances and speculative possibility. It is natural to suppose, that as much as has been done to-day may be done to-morrow; but on the morrow some difficulty emerges or some external impediment obstructs. Indolence, interruption, business, and pleasure; all take their turns of retardation; and every long work is lengthened by a thousand causes that can, and ten thousand that cannot, be recounted. Perhaps no extensive and multifarious performance was ever effected within the term originally fixed in the undertaker's mind. He that runs against Time, has an antagonist not subject to casualties.
From Samuel Johnson's Lives of the Poets series, published in 3 volumes between 1779 and 1781, on Alexander Pope — Samuel Johnson

Speculative fiction includes all stories that take place in a setting contrary to known reality. — Orson Scott Card

You sit beside the sorcerer, your love, and unzip your ribs. Tucked under your heart is a small oak box, plain and unvarnished. You offer it to the sorcerer. 'I brought this for you. — A. Merc Rustad

The iPod is not a new category. Music is not new. It's not a speculative market. It's a very, very large market. It's been around for thousands of years and will be around as long as humans exist. — Steve Jobs

As for myself, I can only exhort you to look on Friendship as the most valuable of all human possessions, no other being equally suited to the moral nature of man, or so applicable to every state and circumstance, whether of prosperity or adversity, in which he can possibly be placed. But at the same time I lay it down as a fundamental axiom that "true Friendship can only subsist between those who are animated by the strictest principles of honour and virtue." When I say this, I would not be thought to adopt the sentiments of those speculative moralists who pretend that no man can justly be deemed virtuous who is not arrived at that state of absolute perfection which constitutes, according to their ideas, the character of genuine wisdom. This opinion may appear true, perhaps, in theory, but is altogether inapplicable to any useful purpose of society, as it supposes a degree of virtue to which no mortal was ever capable of rising. — Marcus Tullius Cicero

Regarding speculative matters that are of no practical moment, and followed by no consequences to himself, farther, perhaps, than that they foster his vanity the better the more remote they are from common sense; requiring, as they must in this case, the exercise of greater ingenuity and art to render them probable. — Rene Descartes
