Animal Brain Quotes & Sayings

The more I dim my eyes over print and frazzle my brain over abstract ideas, the more I appreciate the delight of being basically an animal wrapped in a sensitive skin: sex, the resistance of rock, the taste and touch of snow, the feel of the sun, good wine and a rare beefsteak and the company of friends around a fire with a guitar and lousy old cowboy songs. Despair: I'll never be a scholar, never be a decent good Christian. Just a hedonist, a pagan, a primitive romantic — Edward Abbey

In that moment I was deeply grateful to the Gypsies, and for the simplemindedness of the animal part of my brain; that a hot meal and a song and a smile from someone I cared about could be enough to distract me from all that darkness, if only for a little while. Then — Ransom Riggs

Yes, but I say that Nature is our enemy, that we must always fight against Nature, for she is continually bringing us back to an animal state. You may be sure that God has not put anything on this earth that is clean, pretty, elegant or accessory to our ideal; the human brain has done it. — Guy De Maupassant

When we awake it is the animal, the plant, that thinks in us. Primitive thought without the least disguise. We see a terrible universe, because we see clearly. A little later, intelligence introduces its impeding contrivances. It brings the little toys which man invents in order to hide the void. It is then that we think we are seeing clearly. We attribute our uneasiness to the miasmas of the brain as it passes from dream to reality. — Jean Cocteau

A fly with a brain the size of a salt grain has the behavioral repertoire nearly as complex as a much larger animal such as a mouse. That's a super-interesting problem from an engineering perspective. — Michael Dickinson

Really' isn't a word we should use with simple confidence. If a neutrino had a brain which had evolved in neutrino-sized ancestors, it would say that rocks 'really' do consist mostly of empty space. We have brains that evolved in medium-sized ancestors, who couldn't walk through rocks, so our 'really' is a 'really' in which rocks are solid. 'Really', for an animal, is whatever its brain needs it to be, in order to assist its survival. And because different species live in such different worlds, there will be a troubling variety of 'reallys'. — Richard Dawkins

The combination of the Main brain with its central nervous system, and the ancient Animal Brain with its somatic, enteric nervous system in the inner body - in the gut - and the constant dialog between them provides a self-correcting feedback system, which regulates the behavioral qualities of the organism when consciously cultivated - preferably in early youth. — Martha Char Love

I was sure that if I could just scale this fortress I would reach a height with a sunny blue sky and fresh air. I would stand there and experience myself as redeemable rather than ruined. I had no idea what kind of animal I was facing.
If you had suggested to me at the time that my problems were due to some faulty wiring, some chemistry experiment gone wrong in my brain, I'd have said you were suggesting that I not take responsibility for my own choices. Now I know I was wrong. Now when I'm haunted by the specter of depression, I recognize it for what it is. I don't systematically dismantle my life every time depression pops out from behind a tree. But at that time, I was sure it was fixable if the world would just change faster, or if I would. — Jillian Lauren

We live longer and healthier lives than ever before. Animal research has improved the treatment of infections, helped with immunisation, improved cancer treatment and had a big impact on managing heart disease, brain disorders, arthritis and transplantation. — Robert Winston

This is the most exciting part of being human. It is using our brains in the highest way. Otherwise we are just healthy animals — Edwin Land

I believe that the best way to create good living conditions for any animal, whether it's a captive animal living in a zoo, a farm animal or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal's emotions rights, we will have fewer problem behaviors ... All animals and people have the same core emotion systems in the brain. — Temple Grandin

Wherefore the brain must be looked upon as the universal and general sensory and at the same time as the universal and general motory organ of the body and finally as the universal and general laboratory of the animal spirits and the blood or of the essential juices of life. — Emanuel Swedenborg

The brain seems a thoroughfare for nerve-action passing its way to the motor animal. It has been remarked that Life's aim is an act not a thought. To-day the dictum must be modified to admit that, often, to refrain from an act is no less an act than to commit one, because inhibition is coequally with excitation a nervous activity. — Charles Scott Sherrington

Researches still don't have an explanation for the differnece between the sizes of dogs' and wolves' brains - or for why every species of domesticated animal, from ducks and geese to horses and pigs, also has a smaller brain than its wild ancestor. The reason or reasons domestication always leads to smaller brains are hotly debated; but the effects are universal. Anthropologists have documented the same change in Homo sapiens: the brains of modern humans have shrunk about 10 percent over the last ten thousand years. — Virginia Morell

It is because of his brain that [modern man] has risen above the animals. Guess which animals he has risen above. — Will Cuppy

De Grey describes his goal as "engineered negligible senescence" - stopping the body and brain from becoming more frail and disease-prone as it grows older.18 As he explains, "All the core knowledge needed to develop engineered negligible senescence is already in our possession - it mainly just needs to be pieced together."19 De Grey believes we'll demonstrate "robustly rejuvenated" mice - mice that are functionally younger than before being treated and with the life extension to prove it - within ten years, and he points out that this achievement will have a dramatic effect on public opinion. Demonstrating that we can reverse the aging process in an animal that shares 99 percent of our genes will profoundly challenge the common wisdom that aging and death are inevitable. Once robust rejuvenation is confirmed in an animal, there will be enormous competitive pressure to translate these results into human therapies, which should appear five to ten years later. — Ray Kurzweil

He was an animal. He was terrifying. And he was beautiful. I realized that I was biting my lip, that my hand was wound into the ruffled fabric at my chest. Something in me was drawn to the carnage. Like so many women before me, I was a slave to the caveman brain, that deep old part of my DNA that whispered that ferocity would keep me safe and fed and alive and that I should most definitely find the fiercest creature around and hump it. — Delilah S. Dawson

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

A dog starv'd at the master's gate
Predicts the ruin of the State.
A horse misus'd upon the road
Calls to heaven for human blood.
Each outcry of the hunted hare
A fibre from the brain does tear,
A skylark wounded on the wing,
A cherubim does cease to sing. — William Blake

Most people may not realize the tremendous value that therapy/companion/comfort animals have for the purposes of easing the suffering of those with PTSD and Traumatic Brain Injury (TBI), particularly within the military. — Ken Wahl

So my eyes spotted it and my brain processed it and rejected it instantly, on a purely preprogrammed basis. And then it hung up on it. Out of pure animal instinct. Because it looked like a snake. The lizard part of my brain whispered snake and I got that little primeval jolt of fright that had kept my ancestors alive and well way back in evolution. It was all over in a split second. It was smothered immediately. The modern educated part of my mind stepped in and said, No snakes here in January, bud. Way too cold. I breathed out and moved on a step and then paused to look back, purely out of curiosity. — Lee Child

When an animal is looking for something that increases its chances of survival and reproduction (e.g. food, partners or social status), the brain produces sensations of alertness and excitement, which drive the animal to make even greater efforts because they are so very agreeable. In a famous experiment scientists connected electrodes to the brains of several rats, enabling the animals to create sensations of excitement simply by pressing a pedal. When the rats were given a choice between tasty food and pressing the pedal, they preferred the pedal (much like kids preferring to play video games rather than come down to dinner). The rats pressed the pedal again and again, until they collapsed from hunger and exhaustion — Yuval Noah Harari

Denial, when one was accused, was a life force, and would trump any desire to confess. Perhaps this was the animal strength of the psychopathic brain. Or the psychopathy of the animal brain. An admission of guilt would knock the strength right out of you - making it easier for them to twist your arms behind you and put the handcuffs on. — Lorrie Moore

A big seizure just kind of grabs the inside of your skull and squeezes. It feels as if it's twisting and turning your brain all up and down and inside out. Have you ever heard a washing machine suddenly flip into that bang-bang-bang sound when it gets out of balance, or a chain saw when the chain breaks and gets caught up in the gears, or an animal like a cat, screeching in pain? Those are what seizures felt like when I was little. — Terry Trueman

GG Allin is an entertainer with a message to a sick society. He makes us look at it for what we really are. The human is just another animal who is able to speak out freely, to express himself clearly. Make no mistake about it, behind what he does is a brain. — John Wayne Gacy

I consider the differences between man and animals in propensities, feelings, and intellectual faculties, to be the result of the same cause as that which we assign for the variations in other functions, viz. difference of organization; and that the superiority of man in rational endowments is not greater than the more exquisite, complicated, and perfectly developed structure of his brain, and particularly of his ample cerebral hemispheres, to which the rest of the animal kingdom offers no parallel, nor even any near approximation, is sufficient to account for. — Sir William Lawrence, 1st Baronet

Plants don't think. Animals are guided by the power of instinct over which they themselves have no control. Animals have a certain kind of brain that makes it impossible to learn anything except very simple things. No generation of animals ever learns anything from any previous generation. We act like animals when we fail to use this magnificent piece of equipment. — Sterling W. Sill

I believe that this hairless embryo with the aching, oversize brain case and the opposable thumb, this animal barely up from the apes, will endure
will endure longer than his home planet, will spread out to the other planets, to the stars, and beyond, carrying with him his honesty, his insatiable curiosity, his unlimited courage
and his noble essential decency.
This I believe with all my heart. — Robert A. Heinlein

Peeping through my keyhold I see within the range of only about 30 percent of the light that comes from the sun; the rest is infrared and some little ultraviolet, perfectly apparent to many animals, but invisible to me. A nightmare network of ganglia, charged and firing without my knowledge, cuts and splices what I see, editing it for my brain. Donald E. Carr points out that the sense impressions of one-celled animals are not edited for the brian: 'This is philosophically interesting in a rather mournful way, since it means that only the simplest animals perceive the universe as it is. — Annie Dillard

At still higher doses psilocybin triggers this activity in the language-forming capacity of the brain that manifests as song and vision. Psilocybin may have synergized the emergence of higher forms of psychic organization out of primitive protohuman animals. It can be seen as a kind of evolutionary enzyme, or evolutionary catalyst. — Terence McKenna

It was unrelenting and painful as it clawed and clouded his brain, reducing him to a saliva-ridden animal desperate to eviscerate the Jinn who dared to hurt what was his.
Young, Samantha (2011-10-19). Smokeless Fire (Fire Spirits) (Kindle Locations 5302-5303). Kindle Edition. — Samantha Young

Of course, when a poem is being born, the reasoning part of the brain throbs away at full throttle, but all the other areas are overlapping and interacting as well, the emotional, intuitive, animal areas. — Michael Longley

The brain of man, like that of all animals is double, being parted down its centre by a thin membrane. For this reason pain is not always felt in the same part of the head, but sometimes on one side, sometimes on the other, and occasionally all over. — Hippocrates

The human species was given dominion over the earth and took the opportunity to exterminate other species and warm the atmosphere and generally ruin things in its own image, but it paid this price for its privileges: that the finite and specific animal body of this species contained a brain capable of conceiving the infinite and wishing to be infinite itself. — Jonathan Franzen

Much of the early work focused on dopamine and we were really looking for rewarding sorts of effects and sure enough, we only found that. But you can destroy the main dopamine-producing structures of the brain and you can still get an animal to self-administer drugs like cocaine. — Carl Hart

An animal experiment cannot be justifiable unless the experiment is so important that the use of a brain-damaged human would be justifiable. — Peter Singer

do other animals have human emotions? Yes, they do. Do humans have animal emotions? Yes; they're largely the same. Fear, aggression, well-being, anxiety, and pleasure are the emotions of shared brain structures and shared chemistries, originated in shared ancestry. — Carl Safina

Running is for animals. You need a brain and a ball for football. — Louis Van Gaal

The back and center part of our brains, containing the brain stem, cerebellum, and basal ganglia, are almost identical to the brains of reptiles. Known as the "reptilian brain," these are the oldest structures of the brain, governing basic animal functions such as balance, breathing, digestion, heartbeat, and blood pressure. They also control behaviors such as fighting, hunting, mating, and territoriality, which are necessary for survival and reproduction. The reptilian brain can be traced back about 500 million years. (See Figure 3.) — Michio Kaku

I do not believe that it could never be justifiable to experiment on a brain-damaged human. — Peter Singer

For us to remain in this world, our animal brain has to be there to support us. — Thomas Keating

Institutions are "stable, valued, recurring patterns of behavior," as Huntington put it, the most important function of which is to facilitate collective action. Without some set of clear and relatively stable rules, human beings would have to renegotiate their interactions at every turn. Such rules are often culturally determined and vary across different societies and eras, but the capacity to create and adhere to them is genetically hard-wired into the human brain. A natural tendency to conformism helps give institutions inertia and is what has allowed human societies to achieve levels of social cooperation unmatched by any other animal species. — Anonymous

You're looking at a species of flimsy little two-legged animals with extremely small heads whose name is Man ... Very tiny undeveloped brain; comes from primitive planet named Earth. Calls himself 'Samuel Conrad'. And he will remain here in his cage with the running water and the electricity and the central heat- as long as he lives. Samuel Conrad has found the Twilight Zone. — Rod Serling

Though it was long thought that woman's brain was minor in comparison with man's, woman, as a class, now-a-day shows an all-round activity; and has brought staid control to official actions which had had a long run through domination by man; - that proud, cocky, strutting animal who thinks that this gigantic world should hop, skip and jump at his commands. — Ernest Vincent Wright

Imagine a forty-five-year-old male fifty feet long, a slim, shiny black animal cutting the surface of green ocean water at twenty knots. At fifty tons it is the largest carnivore on earth. Imagine a four-hundred-pound heart the size of a chest of drawers driving five gallons of blood at a stroke through its aorta; a meal of forty salmon moving slowly down twelve-hundred feet of intestine ... the sperm whale's brain is larger than the brain of any other creature that ever lived ... With skin as sensitive as the inside of your wrist. — Barry Lopez

This neuronal correlate of consciousness - the transient assembly - satisfies all the items on the shopping list of phenomena above. The efficacy of an alarm clock is explained as a very vigorous sensory input that triggers a large, synchronous assembly. Dreams and wakefulness differ because dreams result from a small assembly driven by weak internal stimuli, whereas wakefulness results from a larger assembly driven by stronger external stimuli. Anesthetics restrict the size of assemblies, thus inducing unconsciousness. Self-consciousness can arise only in a brain large and interconnected enough to devise extensive neuronal networks. The degree of consciousness in an animal or a human fetus depends on the sizes of their assemblies, too. — Scientific American

Yoga talks about cat-pose, dog-pose, camel-pose, monkey-pose, bird-pose etc. Why there are so many animal poses? Animals release their emotions and tensions by movements based on their body sensations. But our amygdala in the brain is carrying the "fight or flight response"; it has forgotten the art of releasing the tensions. As human beings, when we are aware about the sensations, we can release that by aware, slow movements. If you do not give movements to the body parts, energy will be stuck and blood circulation will be disturbed. Gradually, that creates chronic physical and mental health problems. — Amit Ray

Most kids who grow up in Alaska and spend a fair degree of time in the wilderness, grow up being pretty self-reliant. You have to be, in order to survive all the animals and cliffs and crevasses and rapids - at some point, your brain has to kick [out of] that childish daydream world and start making I-want-to-live decisions. — Leigh Newman

Animals are like autistic savants. In fact, I'd go so far as to say that animals might actually be autistic savants. Animals have special talents normal people don't, the same way autistic people have special talents normal people don't; and at least some animals have special forms of genius normal people don't, the same way some autistic savants have special forms of genius. I think most of the time animal genius probably happens for the same reason autistic genius does: a difference in the brain autistic people share with animals. — Temple Grandin

Humans socialize in the largest groups of all primates because we are the only animals with brains large enough to handle the complexities of that social arrangement. — Malcolm Gladwell

I'm not sure why Setne didn't just magic himself away. I suppose even a powerful magician can succumb to panic. When you're free-falling, you forget to think rationally: Gee, I have spells and stuff. Instead your animal brain takes over and you think: OH MY GOD THIS KID IS HOLDING ON TO ME AND I'M TRAPPED AND FALLING AND I'M GOING TO DIE! — Rick Riordan

One can truly say that the irresistible progress of natural science since the time of Galileo has made its first halt before the study of the higher parts of the brain, the organ of the most complicated relations of the animal to the external world. And it seems, and not without reason, that now is the really critical moment for natural science; for the brain, in its highest complexity - the human brain - which created and creates natural science, itself becomes the object of this science. — Ivan Pavlov

Our inventions have long been ahead of us in terms of efficiency and sanity, productivity and predictability. Oh, how we've wished we could be manmade, too. What has been keeping us back, keeping us messy? The animal impediment, within and without. Eliminating these impediments, we will surely be catching up with our machines, resembling them more and more impeccably. — Amy Leach

I have explained many times that I am, by Profession, a Gambler
not some jock-sniffing nerd or a hired human squawk-box with the brain of a one-cell animal. No. That would be your average career sportswriter
and, more specifically, a full-time Baseball writer. — Hunter S. Thompson

An older, inebriated Scot who looked like he'd been sitting on his barstool all day looked me up and down, then smelled the air. "Heh, neebr, goat a deid an'mal in yer bac'pac, or iz it ye tha' bloody stinks?"
My brain took a moment to translate. "Actually, yes, there is a dead animal in my backpack, but I probably stink, too. — Steve Alten

Weyler, the brute, the devastator of haciendas, and the outrager of women . . . is pitiless, cold, an exterminator of men," ran one such account. "There is nothing to prevent his carnal, animal brain from running riot with itself in inventing tortures and infamies of bloody debauchery. — Stephen Kinzer

The half-brained creature to whom books are other than living things may see with the eyes of a bat and draw with the fingers of a mole his dullard's distinction between books and life: those who live the fuller life of a higher animal than he know that books are to poets as much part of that life as pictures are to painters or as music is to musicians, dead matter though they may be to the spiritually still-born children of dirt and dullness who find it possible and natural to live while dead in heart and brain. — Algernon Charles Swinburne

But maybe that is not possible; maybe, in fact, the brainlessness of the box jellyfish is a direct consequence of its tremenous powers of sight. Perhaps neither the animal nor the prophet has been invented who could process so thorough a vision. It is disquieting enough to be hyperacute or hypersensitive; perhaps being both would very soon melt your brain and leave you quiescent, hanging transparently in the giant dancing green waters of the world. — Amy Leach

An immune system of enormous complexity is present in all vertebrate animals. When we place a population of lymphocytes from such an animal in appropriate tissue culture fluid, and when we add an antigen, the lymphocytes will produce specific antibody molecules, in the absense of any nerve cells. I find it astonishing that the immune system embodies a degree of complexity which suggests some more or less superficial though striking analogies with human language, and that this cognitive system has evolved and functions without assistance of the brain. — Niels Kaj Jerne

As if to demonstrate, by a striking example, the impossibility of erecting any cerebral barrier between man and the apes, Nature has provided us, in the latter animals, with an almost complete series of gradations from brains little higher than that of a Rodent, to brains little lower than that of Man. — Thomas Huxley

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

As a researcher at US Berkeley I used to go into the brains of small, little animals and study the way that brains were connected and how little did I know that one day that was going to be my future - exploring the universe of the brain and hold it in between my hands and look at cells migrating. — Alfredo Quinones-Hinojosa

A somewhat casual observer from outer space might well deduce that the course of evolution in this planet had produced a species of large four-wheeled bugs with detachable brains; peculiar animals which rested when they sent their brains away from them but performed in rather predictable manner when their brains were recalled. — Kenneth E. Boulding

By exerting its will, Descartes declared, the immaterial human mind could cause the material human machine to move. This bears repeating, for it is an idea that, more than any other, has thrown a stumbling block across the path of philosophers who have attempted to argue that the mind is immaterial: for how could something immaterial act efficaciously on something as fully tangible as a body? Immaterial mental substance is so ontologically different-that is, such a different sort of thing-from the body it affects that getting the twain to meet has been exceedingly difficult. To be sure, Descartes tried. He argued that the mental substance of the mind interacts with the matter of the brain through the pineal gland, the organ he believed was moved directly by the human soul. The interaction allowed the material brain to be physically directed by the immaterial mind through what Descartes called "animal spirits"-basically a kind of hydraulic fluid. — Jeffrey M. Schwartz

Emotion is not a defect in an otherwise perfect reasoning machine. Reason, unfettered from human feeling, has led to as many horrors as any crusader's zeal. What use is pity in a world devoted to maximizing efficiency and productivity? Scientific husbandry tells us to weed out the sick, the infirm, the weak. The ruthless efficiency of euthanasia initiatives and ethnic cleansing are but the programmatic application of Nietzsche's point: from any quantifiable cost-benefit analysis, the principles of animal husbandry should apply to the human race. Charles Darwin himself acknowledged that strict obedience to "hard reason" rather than sympathy for fellow humans would represent a sacrifice of "the noblest part of our nature."6 It is the human heart resonating with empathy, not the logical brain attuned to the mathematics of efficiency, that revolts at cruelty and inhumanity. In — Terryl L. Givens

A fierce and monkish art; a castigation of the flesh. You must cut out your imagination and not fly an airplane but regulate a half-dozen instruments ... At first, the conflicts between animal sense and engineering brain are irresistibly strong. — Wolfgang Langewiesche

It can't be more than a quarter of a mile to the finish, but it seems to go on forever. Do I really have to do this? My legs are entirely dead. Would it really matter if I stopped here?
But I know I'd regret it if I did, so I plod leadenly on, distracting myself...with the thought that, whatever troubles I may have been carrying around in my head before the race, I have now entirely forgotten what they were. This thought is rather refreshing. Whatever physical pains it has involved, this ordeal has utterly absorbed me, forcing my brain to focus on the kind of concerns for which it evolved - navigation, survival, balance, digging deep - rather than on the fretful urban anxieties to which it has become habituated. Reconnecting with your inner animal, I suppose you could call it; and it feels good. Especially when, blissfully, I catch sight of the finish. — Richard Askwith

The brain has a good error rate. But, the point is, you can function with that error rate. Animals do a lot of guesswork. — Usama Fayyad

Suddenly she thought that these men believed feeling itself a disease, something to be cut out like a rotten appendix. Cold, calculating, ambitious, believing themselves rational and superior, they chased the crouching female animal through the brain with a scalpel. From an early age she had been told that what she felt was unreal and didn't matter. Now they were about to place in her something that would rule her feelings like a thermostat — Marge Piercy

Time if the inner form of animal sense that animates events-the still frames-of the spatial world. The mind animates the world like the motor and gears of a projector. Each weaves a series of still pictures-a series of spatial states-into an order, into the 'current' of life. Motion is created in our minds by running "film cells" together. Remember that everything you perceive-even this page-is actively, repeatedly, being constructed inside your head. It's happening to you right now. Your eyes cannot see through the wall of the cranium; all experience including visual experience is an organized whirl of information in your brain. If your mind could stop its "motor" for a moment, you'd get a freeze frame, just as the movie projector isolated the arrow in one position with no momentum. In fact, time can be defined as the inner summation of spatial states. — Robert Lanza

I am a vegetarian as well as a passionate anti-alcoholic, because I can thus make better use of my brain. — Thomas A. Edison

Yes, all of life is sacred, including plants; and yes, there is research that demonstrates that plants have feelings - they feel it when their leaves or stems are ripped - and there is scientific evidence that while plants do not have brains and nervous systems like animals, they nevertheless actively work to ensure their survival - they want to live, thrive, reproduce, evolve. — Sharon Gannon

...Without death, now, there couldn't be life. Health," he said with a little smiling roll of his lower lip, "is an animal condition. Now most of our ill-health comes from two places-the brain and the back. We made two mistakes; one was to stand up and the other was to start thinking. It strains the spine and the nerves. It makes tension and the brain makes the body. — John Updike

American scientific companies are cross-breeding humans and animals and coming up with mice with fully functioning human brains. — Christine O'Donnell

Of all the unexpected qualities of an unexpected universe, the sheer organizing power of animal and plant metabolism is one of the most remarkable ... Where it reaches its highest development, in the human mind, we forget it completely ... So important does nature regard this unseen combustion ... that a starving man's brain will be protected to the last while his body is steadily consumed. — Loren Eiseley

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

If you stimulate seizures in an animal every day, the seizures eventually become automatic; the animal will go on having them once a day even if you withdraw the stimulation. In much the same way, the brain that has gone into depression a few times will continue to return to depression over and over. This suggests that depression, even if it is occasioned by external tragedy, ultimately changes the structure, as well as the biochemistry, of the brain. — Andrew Solomon

Or did a Martian sit within each, ruling, directing, using, much as a man's brain sits and rules in his body? I began to compare the things to human machines, to ask myself for the first time in my life how an ironclad or a steam engine would seem to an intelligent lower animal. — H.G.Wells

Here are three separate but similar things: shyness, introversion and social anxiety. You can have one, two or all three of these things simultaneously. A lot of the time people thing they're all the same thing, but that's just not true. Extroverts can be shy, introverts can be bold, and a condition like anxiety can strike whatever kind of social animal you are.

Lots of people are shy. Shy is normal. A bit of anxiety is normal. Throw the two together, add some brain-signal error - a NO ENTRY sign on the neural highway from my brain to my mouth perhaps, though no one really knows - and you have me. — Sara Barnard

Dominion does not mean domination. We hold dominion over animals only because of our powerful and ubiquitous intellect. Not because we are morally superior. Not because we have a "right" to exploit those who cannot defend themselves. Let us use our brain to move toward compassion and away from cruelty, to feel empathy rather than cold indifference, to feel animals' pain in our hearts. — Marc Bekoff

We're physical objects, we think of ourselves as these kind of free-floating brains, but the brain is such a little part. It's way smaller than we like to think. We think we're these important human beings. We're not animals or anything. But what did we come out of? What are we made out of? We're made of the same stuff as out there. — Melissa Holbrook Pierson

An electronic computer is also made up of matter, but organised differently; what is there so magical about the workings of the huge, slow cells of the animal brain that they can claim themselves to be conscious, but would deny a quicker, more finely-grained device of equivalent power - or even a machine hobbled so that it worked with precisely the same ponderousness - a similar distinction? — Iain M. Banks

Man is not a 'fixed and limited animal whose nature is absolutely constant'. He changed drastically when he developed 'divided consciousness' to cope with complexities of civilisation, and has been changing steadily ever since. His greatest problem, the problem that has caused most of his agonies and miseries, has been his attempt to compensate for the narrowing of cinsciousness and the entrapment in the left-brain ego. His favorite method of compensation has been to seek out excitement. He feels most free in moments of conquest; so for the past three thousand years or so, most of the greatest man have led armies into their neighbours' territority, and turned order into chaos. This has plainly been a retrogressive step; the evolutionary urge has been defeating its own purpose. — Colin Wilson

The animal tends to eat with his stomach, and the man with his brain. When the animal's stomach is full, he stops eating, but the man is never sure when to stop. When he has eaten as much as his belly can take, he still feels empty, he still feels an urge for further gratification. — Alan Watts
