Brain Intelligence Quotes & Sayings

He always reminded us that every atom in our bodies was once part of a distant star that had exploded. He talked about how evolution moves from simplicity toward complexity, and how human intelligence is the highest known expression of evolution. I remember him telling me that a frog's brain is much more complex than a star. He saw human consciousness as the first neuron of the universe coming to life and awareness. A spark in the darkness, waiting to spread to fire. — Greg Iles

[...] It is essentially this you can do with a human that you cannot do with a chimpanzee: train them to contribute modestly to society. To become a well-connected neuron in the collective human brain. Without the knowledge and tools of previous generations, humans are largely indistinguishable from chimpanzees. — Magnus Vinding

with rare exceptions (chiefly the social insects), mammals and birds are the only organisms to devote substantial attention to the care of their young; an evolutionary development that, through the long period of plasticity which it permits, takes advantage of the large information-processing capability of the mammalian and primate brains. Love seems to be an invention of the mammals. — Carl Sagan

While standardized tests can certainly be useful for scientifically investigating the mind and brain, and can greatly inform educational interventions, there's no reason why educators or anyone else for that matter needs to compare the intelligence of one person to another based on a single dimension of human variation. — Scott Barry Kaufman

I've always been amused by the contention that brain work is harder than manual labor. I've never known a man to leave a desk for a muck-stick if he could avoid it. — John Steinbeck

There are many things we don't understand, and many ways to unlock the brain and maximize function. Don't ever let anybody tell you it can't be done. — Sally Fryer Dietz

In order that our art may arrive at the degree of the sublime which I demand and hope for, it is imperative for dancers to divide their time and studies between the mind and the body, and that both become the object of their application; but, unfortunately, all is given to the latter and nothing to the former. The legs are rarely guided by the brain, and, since intelligence and taste do not reside in the feet, one often goes astray. — Jean-Georges Noverre

The level of intelligence has been tremendously increased, because people are thinking and communicating in terms of screens, and not in lettered books. Much of the real action is taking place in what is called cyberspace. People have learned how to boot up, activate, and transmit their brains.
Essentially, there's a universe inside your brain. The number of connections possible inside your brain is limitless. And as people have learned to have more managerial and direct creative access to their brains, they have also developed matrices or networks of people that communicate electronically. There are direct brain/computer link-ups. You can just jack yourself in and pilot your brain around in cyberspace-electronic space. — Timothy Leary

At every level there are eight stages of intelligence. You have to turn your brain on to the circuits that are used at that level of intelligence. And there are ways to change the human brain to different stages. The things that change your brain are called 'drugs'. — Timothy Leary

I'm frequently asked, "Do you believe there's extraterrestrial intelligence?" I give the standard arguments- there are a lot of places out there, the molecules of life are everywhere, I use the word billions, and so on. Then I say it would be astonishing to me if there weren't extraterrestrial intelligence, but of course there is as yet no compelling evidence for it.
Often, I'm asked next, "What do you really think?"
I say, "I just told you what I really think."
"Yes, but what's your gut feeling?"
But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble. Really, it's okay to reserve judgment until the evidence is in. — Carl Sagan

Yes, she answers and does not move. She might, at this moment, be nothing but a floating intelligence; not even a brain inside a skull, just a presence that perceives, as a ghoast might. Yes, she thinks, this is probably how it must feel to be a ghost. It's a little like reading, isn't it-that same sensation of knowing people, settings, situations, without playing any particular part beyond that of the willing observer. — Michael Cunningham

Singularity will be an opt-in scenario for human beings, especially as we draw closer to it. The more that we have the opportunity to interface with and combine ourselves with machines and machinery and electronics - those will all be opt-in moments. Would you choose to have some sort of brain implant? Would you choose to have Google Glasses installed in your eyes? It's all an approach; it's all a glide path to the moment of genuine singularity; genuine artificial intelligence. — Ron Currie Jr.

She has man's brain
a brain that a man should have were he much gifted
and woman's heart. The good God fashioned her for a purpose, believe me when He made that so good combination. — Bram Stoker

[T]he more clamour we make about 'the women's point of view', the more we rub it into people that the women's point of view is different, and frankly I do not think it is
at least in my job. The line I always want to take is, that there is the 'point of view' of the reasonably enlightened human brain, and that this is the aspect of the matter which I am best fitted to uphold. — Dorothy L. Sayers

To have an inner life, to think, to juggle and leap, to become a tightrope walker in the world of ideas. To attack, to riposte, to refute, what a contest, what acclaim. To understand. The most generous word of all. Memory. To retain, a geyser of felicity. Intelligence. The agonizing poverty of my mind. Words and ideas flitting in and out like butterflies. My brain a dandelion seed blown in the wind. — Violette Leduc

There's a heart beneath the boobs and a brain beneath the wig. — Dolly Parton

Very rare, the intelligence of the heart. The intelligence of the whimsical brain is less rare, less attaching, sometimes tedious. — Storm Jameson

The best buy by way of management is brains-at any price. — Malcolm Forbes

Thoughts are dangerous, he told himself, and thoughts against all science, all sanity, all civilized intelligence, are the most dangerous of all. He felt their presence here and there in his brain, like pockets of poison, harmless as long as you left them encysted and did not prick them. — Fritz Leiber

Consider a cognitive scientist concerned with the empirical study of the mind, especially the cognitive unconscious, and ultimately committed to understanding the mind in terms of the brain and its neural structure. To such a scientist of the mind, Anglo-American approaches to the philosophy of mind and language of the sort discussed above seem odd indeed. The brain uses neurons, not languagelike symbols. Neural computation works by real-time spreading activation, which is neither akin to prooflike deductions in a mathematical
logic, nor like disembodied algorithms in classical artificial intelligence, nor like derivations in a transformational grammar. — George Lakoff

To think is to practice brain chemistry. — Deepak Chopra

In the far reaches of her brain a storehouse of demeaning events evidently opened a door for Extra Sensory Perception experiences to enter. — Judy Byington

Around the late 1990s, I'd become convinced that one of the killer applications of robotics came from connecting robots to the Internet. The idea of solving generalized artificial intelligence was still far away, but heck, I could rent brains by hiring operators. iRobot was the name of the company and one of our most ambitious projects, iRobot LE. — Colin Angle

God #1 is the Single-cell Intelligence, the collaborative brain that knows how to run a simple protozoan. The First God is the one-celled God. The First and original craft of God is Protozoan. — Timothy Leary

Um, because you're loopier than Flacky McPsycho, Mayor of Crazytown?"
"My databases show no record of this Crazytown of which you speak. A brain the size of an entire city burns inside me. My intelligence quotient is beyond the human scale. I would prefer if you did not refer to me in such a fashion."
"Oh, poor baby. Did I hurt the mass-murdering psychopathic artificial intelligence's feelings? — Amie Kaufman

There was no evidence that the intelligence of the human race had improved, but for the first time everyone was given the fullest opportunity of using what brain he had. — Arthur C. Clarke

AI scientists tried to program computers to act like humans without first answering what intelligence is and what it means to understand. They left out the most important part of building intelligent machines, the intelligence! "Real intelligence" makes the point that before we attempt to build intelligent machines, we have to first understand how the brain thinks, and there is nothing artificial about that. Only then can we ask how we can build intelligent machines — Jeff Hawkins

There are no inherent barriers to our being able to reverse engineer the operating principles of human intelligence and replicate these capabilities in the more powerful computational substrates that will become available in the decades ahead. The human brain is a complex hierarchy of complex systems, but it does not represent a level of complexity beyond what we are already capable of handling. — Ray Kurzweil

I usually say the aim of life is to be happy. Our existence is based on hope. Our life is rooted in the opportunity to be happy, not necessarily wealthy, but happy within our own minds. If we only indulge in sensory pleasure, we'll be little different from animals. In fact, we have this marvellous brain and intelligence; we must learn to use it. — Dalai Lama

The intelligence we will create from the reverse-engineering of the brain will have access to its own source code and will be able to rapidly improve itself in an accelerating iterative design cycle. Although there is considerable plasticity in the biological human brain, as we have seen, it does have a relatively fixed architecture, which cannot be significantly modified, as well as a limited capacity. We are unable to increase its 300 million pattern recognizers to, say, 400 million unless we do so nonbiologically. Once we can achieve that, there will be no reason to stop at a particular level of capability. We can go on to make it a billion pattern recognizers, or a trillion. — Ray Kurzweil

Your brain is the organ of your personality, character, and
intelligence and is heavily involved in making you who you are. — Daniel G. Amen

We must develop as quickly as possible technologies that make possible a direct connection between brain and computer, so that artificial brains contribute to human intelligence rather than opposing it. — Stephen Hawking

And eventually even the brain might go. As the seat of consciousness, it was not essential; the development of electronic intelligence had proved that. The conflict between mind and machine might be resolved at last in the eternal truce of complete symbiosis ... . But — Arthur C. Clarke

She was a clever girl, but she filled that brain of hers with far too much fluff on the types of gowns and the styles of bonnets. Then again, he shouldn't be wishing her intelligence was put to use elsewhere. Lord knows the little chit might end up a brilliant political hostess or married to a member of the House of Lords. He wouldn't give her credit for anything less and the very idea of her having any influence over a man in politics was terrifying.

-Lucien's thoughts about Audrey. His Wicked Seduction — Lauren Smith

If there are as many connections in your brain as there are stars in the universe, why ask for superpowers? — Clementine Beauvais

For the record," I do not desire your body. Not that you're hideous or anything, far from it. Even with those scars, your chest is really nice, and I like your legs because they aren't scrawny, and you have nice shoulders and naughty bits, but I've never been one to put physical attributes ahead of more important things."
"Such as?" He had his hands on his hips when he asked the question, which just made me want to giggle again.
"Intelligence, a sense of humor, and oh yes, not being a mythical creature." I swallowed another giggle. "Not that it wasn't a cool form, but still. I like my men without the sort of baggage that must go with being a shape-shifter."
"Is that so?" One eyebrow lifted.
"Yes."
"Then you will not like this." He pulled me against him, his mouth moving into place on mine, his breath hotter than I could have imagined. And then he kissed the very wits right out of my brain. — Katie MacAlister

There's a popular concept of 'intelligence' as book smarts, like calculus or chess, as opposed to, say, social skills. So people say that 'it takes more than intelligence to succeed in human society.' But social skills reside in the brain, not the kidneys. — Eliezer Yudkowsky

According to a recent study of the brains of identical and fraternal twins, differences in the amount of gray matter in the frontal lobes are not only genetically influenced but are significantly correlated with differences in intelligence. — Steven Pinker

Anyone who endeavors to be a Christian will soon find his intelligence being sharpened. You are embarking on something that is going to take the whole of you, brains and all. — C.S. Lewis

There's no shame compared to being beautiful with nothing in your brain, an ugly devil with wits is much better that the former. — Michael Bassey Johnson

Via our left hemisphere language centers, our mind speaks to us constantly, a phenomenon I refer to as "brain chatter." It is that voice reminding you to pick up bananas on your way home and that calculating intelligence that knows when you have to do your laundry. There is vast individual variation in the speed at which our minds function. For some, our dialogue of brain chatter runs so fast that we can barely keep up with what we are thinking. Others of us think in language so slowly that it takes a long time for us to comprehend. Still others of us have a problem retaining our focus and concentration long enough to act on our thoughts. These variations in normal processing stem back to our brain cells and how each brain is intrinsically wired. — Jill Bolte Taylor

Through Transcendental Meditation, the human brain can
experience that level of intelligence which is an ocean of all
knowledge, energy, intelligence, and bliss. — Maharishi Mahesh Yogi

Catholicism is the tomb of intelligence, of thought, of brain; Protestantism, the tomb of conscience, of feeling, of heart. — Louis Auguste Blanqui

If the blonds and blue-eyed people die out, the human race will become increasingly dense ... Blond hair actually bestows intelligence. In the case of fair people, less nourishment is driven into the eyes and hair; it remains instead in the brain and endows it with intelligence. Brown- and dark-haired people drive the substances into their eyes and hair that the fair people retain in their brains. — Rudolf Steiner

To construct mechanically the brain of a somniferous tale, it is not enough to dissect nonsense & mightily stupefy the reader's intelligence with renowned doses, so as to paralyze his faculties for the rest of his life by the infallible law of fatigue; one must, besides, with good mesmeric fluid, make it somnambulistically impossible for him to move, against his nature forcing his eyes to cloud over at your own fixed stare. — Comte De Lautreamont

The development of artificial intelligence may well imply that man will relinquish his intellectual supremacy in favor of thinking machines. With oceans of time available for future innovation, there seems to be no reason why machines cannot achieve and surpass anything of which the human brain is capable. — Paul Davies

I think the sexiest thing on anybody is intelligence. I respect somebody who has a brain and wants to use it more than a pretty face and status. — Sophia Bush

It is good to rub and polish our brain against that of others. — Michel De Montaigne

The primary implication is that we're going to combine our intelligence with computers. We're going to make ourselves smarter. By the 2030s, they will literally go inside our bodies and inside our brains. — Judy Woodruff

Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped onto the other (the computer). — George Johnson

The human MIND seems to work best in the presence of reality. The brain that contains the problem probably also contains the solution. IF the conditions are right, the huge intelligence of the human being surfaces. IDEAS seem to come from nowhere & sometimes STUN US. — Nancy Kline

We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When we think well, we feel good. Understanding is a kind of ecstasy. — Carl Sagan

There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition. — Stephen Hawking

In 2009, Markram said optimistically, "It is not impossible to build a human brain and we can do it in ten years. If we build it correctly, it should speak and have an intelligence and behave very much as a human does." He cautions, however, that it would take a supercomputer 20,000 times more powerful than present supercomputers, with a memory storage 500 times the entire size of the current Internet, to achieve this. — Michio Kaku

Supposing there was no intelligence behind the universe, no creative mind. In that case, nobody designed my brain for the purpose of thinking. It is merely that when the atoms inside my skull happen, for physical or chemical reasons, to arrange themselves in a certain way, this gives me, as a by-product, the sensation I call thought. But, if so, how can I trust my own thinking to be true? It's like upsetting a milk jug and hoping that the way it splashes itself will give you a map of London. But if I can't trust my own thinking, of course I can't trust the arguments leading to Atheism, and therefore have no reason to be an Atheist, or anything else. Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God. — C.S. Lewis

The highest activities of consciousness have their origins in physical occurrences of the brain just as the loveliest melodies are not too sublime to be expressed by notes. — W. Somerset Maugham

Because the brain models our sense of self as just another instance of a thing, it is easy for us to project qualities that we only know of from our own minds into other objects. This allows us to imagine intelligence in a rock, a tree, an animal or even a politician. — Sean Hastings

Who knows? Life may just be a Positive Conspiracy bent on putting us in the right place at the right time every living, breathing moment of the day. It just takes a certain kind of perspective to see this. Realizing this can put our "analyzer" on hold, our interpretive mind on "ga-ga" and our hearts on breathless. — Antero Alli

He who joyfully marches to music in rank and file has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would suffice. — Albert Einstein

During my long and intimate acquaintance with Mr. Sherlock Holmes I had never heard him refer to his relations, and hardly ever to his own early life. This reticence upon his part had increased the somewhat inhuman effect which he produced upon me, until sometimes I found myself regarding him as an isolated phenomenon, a brain without a heart, as deficient in human sympathy as he was pre-eminent in intelligence. His aversion to women and his disinclination to form new friendships were both typical of his unemotional character, but not more so than his complete suppression of every reference to his own people. I had come to believe that he was an orphan with no relatives living, but one day, to my very great surprise, he began to talk to me about his brother. — Arthur Conan Doyle

To ask "Where in your brain is intelligence?" is like asking "Where is the voice in the radio?" — Howard Gardner

I don't believe anything I write or say. I regard belief as a form of brain damage, the death of intelligence, the fracture of creativity, the atrophy of imagination. I have opinions but no Belief System (B.S.) — Robert Anton Wilson

The brain is not an organ to be relied upon. — Alexander Blok

This is peculiarly an age in which each of us may, if he do but search diligently, find the literature suited to his mental powers. — P.G. Wodehouse

Mind is not in any one place. Every cell in this body has its own intelligence. The brain is sitting in your head, but mind is all over the place. — Jaggi Vasudev

Dolphins have one of the highest ratios of brain size to body mass in the animal kingdom. Measured in this way, a dolphin's brain is second in size only to that of a human's, and well above that of our closest genetic relative, the chimpanzee. A large brain-to-body size ratio is often considered a hallmark of intelligence, although it's not the only factor. But it is something we humans celebrate in ourselves and regard as key to the flowering of human intelligence. — Virginia Morell

A crucial capability of System 2 is the adoption of "task sets": it can program memory to obey an instruction that overrides habitual responses. Consider the following: Count all occurrences of the letter f in this page. This is not a task you have ever performed before and it will not come naturally to you, but your System 2 can take it on. It will be effortful to set yourself up for this exercise, and effortful to carry it out, though you will surely improve with practice. Psychologists speak of "executive control" to describe the adoption and termination of task sets, and neuroscientists have identified the main regions of the brain that serve the executive function. One of these regions is involved whenever a conflict must be resolved. Another is the prefrontal area of the brain, a region that is substantially more developed in humans than in other primates, and is involved in operations that we associate with intelligence. — Daniel Kahneman

The brain isn't very much like a computer, although it doesn't do a bad job, considering that it's built by unskilled labor and programmed more by pure chance than anything else. — Joe Haldeman

Once upon a time ... the only autonomous intelligences we humans knew of were us humans. We thought then that if humankind ever devised another intelligence that it would be the result of a huge project ... a great mass of silicon and ancient transistors and chips and circuit boards ... a machine with lots of networking circuits, in other words, aping-if you will pardon the expression-the human brain in form and function. Of course, AIs did not evolve that way. They sort of slipped into existence when we humans were looking the other way. — Dan Simmons

There is no more terrible woe upon earth than the woe of the stricken brain, which remembers the days of its strength, the living light of its reason, the sunrise of its proud intelligence, and knows that these have passed away like a tale that is told ... — Ouida

Happiness is such an incredible advantage in our life. When the human brain is positive, our intelligence rises, we stop diverting resources to think about anxiety. — Shawn Achor

It is interesting that it is not the getting of any sort of knowledge that God has forbidden, but, specifically, the knowledge of the difference between good and evil-that is, abstract and moral judgments, which, if they reside anywhere, reside in the neocortex. — Carl Sagan

This process is like starting a fitness regimen for the brain. At the beginning, your muscles burn a little. But over time and with repetition, you become stronger, and the improvements you see in yourself can be remarkable. Becoming a better thinker, just like becoming a better athlete, requires practice. We challenge you to feel the burn. — Sarah Miller Beebe

People rely on intelligence to solve problems, and they are naturally baffled when comprehension proves impotent to effect emotional change. To the neocortical brain, rich in the power of abstractions, understanding makes all the difference, but it doesn't count for much in the neural systems that evolved before understanding existed. Ideas bounce like so many peas off the sturdy incomprehension of the limbic and reptilian brains. The dogged implicitness of emotional knowledge, its relentless unreasoning force, prevents logic from granting salvation just as it precludes self-help books from helping. The sheer volume and variety of self-help paraphernalia testify at once to the vastness of the appetite they address and their inability to satisfy it. (118) — Thomas Lewis

I have only a second rate brain, but I think I have a capacity for action. — Theodore Roosevelt

Telepathy' literally means to feel at a distance, just as 'telephone' is to hear at a distance and 'television' is to see at a distance. The word suggests the communication not of thoughts but of feelings, emotions. Around a quarter of all Americans believe they've experienced something like telepathy. People who know each other very well, who live together, who are practised in one another's feeling tones, associations and thinking styles can often anticipate what the partner will say. This is merely the usual five senses plus human empathy, sensitivity and intelligence in operation. It may feel extrasensory, but it's not at all what's intended by the word 'telepathy'. If something like this were ever conclusively demonstrated, it would, I think, have discernible physical causes -perhaps electrical currents in the brain. Pseudoscience, rightly or wrongly labelled, is by no means the same thing as the supernatural, which is by definition something somehow outside of Nature. — Carl Sagan

But Marisa already knew the answer and it was too late for recrimination. The chance of even a rational discussion of the problem was forever shut out of Mama's brain. A brutal bastard was steadily sucking the intelligence and the very life from the mother who had once been witty, wise and loving. The scourge had a name Marisa had come to equate with hell: Alzheimer's Disease. — Anna Jeffrey

I've got a very nice staff here. People with patience, you know, and good temper, and not too brainy, because if you have people who are brainy, they are bound to be very impatient. — Agatha Christie

Man's brain is, after all, the greatest natural resource. — Karl Brandt

Anything that could give rise to smarter-than-human intelligence - in the form of Artificial Intelligence, brain-computer interfaces, or neuroscience-based human intelligence enhancement - wins hands down beyond contest as doing the most to change the world. Nothing else is even in the same league. — Eliezer Yudkowsky

She was afraid of all that and so much more, but what terrified her most was inside of her, an insect of unnatural intelligence who'd been living in her brain her entire life, playing with it, clicking across it, wrenching loose its cables on a whim. — Dennis Lehane

Most people think that intelligence is about brain, where really it's about focus. Genius is just attention to a subject until it becomes specific, specific, specific. — Esther Hicks

When we are angry we are blind to reality. Anger may bring us a temporary burst of energy, but that energy is blind and it blocks the part of our brain that distinguishes right from wrong. To deal with our problems, we need to be practical and realistic. If we are to be realistic, we need to use our human intelligence properly, which means we need a calm mind. — Dalai Lama

The brain is your emotional cockpit. Lots of buttons and levers. Best to learn how to steer responsibly. — Lisa Cypers Kamen

But, stop and think. What does the word 'witch' truly mean?" "Why - " said Tom, and was stymied. "Wits," said Moundshroud. "Intelligence. That's all it means. Knowledge. So any man, or woman, with half a brain and with inclinations toward learning had his wits about him, eh? And so, anyone too smart, who didn't watch out, was called - " "A witch!" said everyone. "And some of the smart ones, the ones with wits, pretended at magic, or dreamed themselves with ghosts and dead shufflers and ambling mummies. And if enemies dropped dead by coincidence, they took credit for it. They liked to believe they had power, but they had none, boys, none, sad and sorry, 'tis true. But — Ray Bradbury

Your brain doesn't know what it cannot do until you tell it. — Ed Strachar

But then human beings only understood each other in the first place by pretending. You didn't make predictions about people by modeling the hundred trillion synapses in their brain as separate objects. Ask the best social manipulator on Earth to build you an Artificial Intelligence from scratch, and they'd just give you a dumb look. You predicted people by telling your brain to act like theirs. You put yourself in their place. If you wanted to know what an angry person would do, you activated your own brain's anger circuitry, and whatever that circuitry output, that was your prediction. What did the neural circuitry for anger actually look like inside? Who knew? The best social manipulator on Earth might not know what neurons were, and neither might the best Legilimens. — Eliezer Yudkowsky

In this century, not only has science changed the world faster than ever, but in new and different ways. Targeted drugs, genetic modification, artificial intelligence, perhaps even implants into our brains - may change human beings themselves. — Martin Rees

No one knows when a robot will approach human intelligence, but I suspect it will be late in the 21st century. Will they be dangerous? Possibly. So I suggest we put a chip in their brain to shut them off if they have murderous thoughts. — Michio Kaku

Personality is a slot machine, and the cherries, lemons, and bells are your SSRI system, your schizophrenic tendency, your left/right brain lobalization, your anxiety proclivity, your wiring glitches, your place on the autistic and OCD spectrums - and to these we must add the deep-level influences of the machines and systems of intelligence that guided your brain into maturity. — Douglas Coupland

This moment of lucidity does not last long. But it serves as the punishment for your sins, a Promethean entrails-pecking moment, crouching half-horse half-man, with the knowledge that you cannot appreciate the destination without knowing the starting point; you cannot revel in the simplicity unless you remember the alternatives.
And that's not the worst of your revelation. You realize that the next time you return here, with your thick horse brain, you won't have the capacity to ask to become a human again. You won't understand what a human is. Your choice to slide down the intelligence ladder is irreversible. And just before you lose your final human faculties, you painfully ponder what magnificent extraterrestrial creature, enthralled with the idea of finding a simpler life, chose in the last round to become a human. — David Eagleman

In the recumbence of depression, your information-gathering system collates its intelligence and reports to you these facts: (1) there is nothing to do; (2) there is nowhere to go; (3) there is nothing to be; (4) there is no one to know. Without meaning-charged emotions keeping your brain on the straight and narrow, you would lose your balance and fall into an abyss of lucidity. And for a conscious being, lucidity is a cocktail without ingredients, a crystal clear concoction that will leave you hung over with reality. In perfect knowledge there is only perfect nothingness, which is perfectly painful if what you want is meaning in your life. — Thomas Ligotti

The great artist is a formulation of the greatest intelligence: he is the recipient of sensations which are the most delicate and consequently the most invisible expressions of the brain. — Paul Gauguin

The talent for self-justification is surely the finest flower of human evolution, the greatest achievement of the human brain. When it comes to justifying actions, every human being acquires the intelligence of an Einstein, the imagination of a Shakespeare, and the subtlety of a Jesuit. — Michael Foley

Those mothers with hereditary large pelvises were able to bear large-brained babies who because of their superior intelligence were able to compete successfully in adulthood with the smaller-brained offspring of mothers with smaller pelvises. — Carl Sagan

Smart thinking is to know what you think and why you think it. — Toni Sorenson

Man cannot survive except through his mind. He comes on earth unarmed. His brain is his only weapon. Animals obtain food by force. man had no claws, no fangs, no horns, no great strength of muscle. He must plant his food or hunt it. To plant, he needs a process of thought. To hunt, he needs weapons,and to make weapons - a process of thought. From this simplest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and we have comes from a single attribute of man -the function of his reasoning mind. — Ayn Rand

Anyone who knew Violet well could tell she was thinking hard, because her long hair was tied up in a ribbon to keep it out of her eyes. Violet had a real knack for inventing and building strange devices, so her brain was often filled with images of pulleys, levers, and gears, and she never wanted to be distracted by something as trivial as her hair. — Lemony Snicket

[Patricia Greenfield] concluded that "every medium develops some cognitive skills at the expense of others." Our growing use of the Net and other screen-based technologies has led to the "widespread and sophisticated development of visual-spatial skills." We can, for example, rotate objects in our minds better than we used to be able to. But our "new strengths in visual-spatial intelligence" go hand in hand with a weakening of our capacities for the kind of "deep processing" that underpins "mindful knowledge acquisition, inductive analysis, critical thinking, imagination, and reflection. — Nicholas Carr

Perhaps the locale of the subjunctive mood will
one day be found. Will Latins turn out to be extravagantly endowed and English-speaking peoples significantly short-changed in this minor piece of brain anatomy? — Carl Sagan
