It is possible to cause seemingly biochemical changes through human emotional involvement. You literally have changed his chemistry by being his friend.
Steve López (The Soloist: A Lost Dream, an Unlikely Friendship, and the Redemptive Power of Music)
The muscles used to make a smile actually send a biochemical message to our nervous system that it is safe to relax the flight of freeze response.
Tara Brach (Radical Acceptance: Embracing Your Life With the Heart of a Buddha)
all addictions—whether to drugs or to non-drug behaviors—share the same brain circuits and brain chemicals. On the biochemical level the purpose of all addictions is to create an altered physiological state in the brain. This can be achieved in many ways, drug taking being the most direct. So an addiction is never purely “psychological”; all addictions have a biological dimension.
Gabor Maté (In the Realm of Hungry Ghosts: Close Encounters with Addiction)
In the abstract, it might be tempting to imagine that irreducible complexity simply requires multiple simultaneous mutations - that evolution might be far chancier than we thought, but still possible. Such an appeal to brute luck can never be refuted... Luck is metaphysical speculation; scientific explanations invoke causes.
Michael J. Behe (Darwin's Black Box: The Biochemical Challenge to Evolution)
The conclusion of intelligent design flows naturally from the data itself—not from sacred books or sectarian beliefs. Inferring that biochemical systems were designed by an intelligent agent is a humdrum process that requires no new principles of logic or science. It comes simply from the hard work that biochemistry has done over the past forty years, combined with consideration of the way in which we reach conclusions of design every day.
Michael J. Behe (Darwin's Black Box: The Biochemical Challenge to Evolution)
What some people hope to get by studying, working or raising a family, others try to obtain far more easily through the right dosage of molecules. This is an existential threat to the social and economic order, which is why countries wage a stubborn, bloody and hopeless war on biochemical crime.
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
Emotions are the lowest form of consciousness. Emotional actions are the most contracted, narrowing, dangerous form of behavior. The romantic poetry and fiction of the last 200 years has quite blinded us to the fact that emotions are an active and harmful form of stupor. Any peasant can tell you that. Beware of emotions. Any child can tell you that. Watch out for the emotional person. He is a lurching lunatic. Emotions are caused by biochemical secretions in the body to serve during the state of acute emergency. An emotional person is a blind, crazed maniac. Emotions are addictive and narcotic and stupefacient. Do not trust anyone who comes on emotional. What are the emotions? In a book entitled Interpersonal Diagnosis of Personality, written when I was a psychologist, I presented classifications of emotions and detailed descriptions of their moderate and extreme manifestations. Emotions are all based on fear. [...] The emotional person cannot think; he cannot perform any effective game action (except in acts of physical aggression and strength). The emotional person is turned off sensually. His body is a churning robot. [...] The only state in which we can learn, harmonize, grow, merge, join, understand is the absence of emotion. This is called bliss or ecstasy, attained through centering the emotions. [...] Conscious love is not an emotion; it is serene merging with yourself, with other people, with other forms of energy. Love cannot exist in an emotional state. [...] The great kick of the mystic experience, the exultant, ecstatic hit, is the sudden relief from emotional pressure. Did you imagine that there could be emotions in heaven? Emotions are closely tied to ego games. Check your emotions at the door to paradise.
Timothy Leary (The Politics of Ecstasy)
Genes are biochemical recipes written in a four-letter alphabet called DNA.
Matt Ridley (The Red Queen: Sex and the Evolution of Human Nature)
This is all the fault of evolution. For countless generations our biochemical system adapted to increasing our chances of survival and reproduction, not our happiness. The
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
Sixty-some years ago, biochemical organisms began to assemble digital computers. Now digital computers are beginning to assemble biochemical organisms. Viewed from a distance, this looks like part of a life cycle. But which part? Are biochemical organisms the larval phase of digital computers? Or are digital computers the larval phase of biochemical organisms?
George Dyson (Turing's Cathedral: The Origins of the Digital Universe)
There is evidence that the honoree [Leonard Cohen] might be privy to the secret of the universe, which, in case you're wondering, is simply this: everything is connected. Everything. Many, if not most, of the links are difficult to determine. The instrument, the apparatus, the focused ray that can uncover and illuminate those connections is language. And just as a sudden infatuation often will light up a person's biochemical atmosphere more pyrotechnically than any deep, abiding attachment, so an unlikely, unexpected burst of linguistic imagination will usually reveal greater truths than the most exacting scholarship. In fact. The poetic image may be the only device remotely capable of dissecting romantic passion, let alone disclosing the inherent mystical qualities of the material world. Cohen is a master of the quasi-surrealistic phrase, of the "illogical" line that speaks so directly to the unconscious that surface ambiguity is transformed into ultimate, if fleeting, comprehension: comprehension of the bewitching nuances of sex and bewildering assaults of culture. Undoubtedly, it is to his lyrical mastery that his prestigious colleagues now pay tribute. Yet, there may be something else. As various, as distinct, as rewarding as each of their expressions are, there can still be heard in their individual interpretations the distant echo of Cohen's own voice, for it is his singing voice as well as his writing pen that has spawned these songs. It is a voice raked by the claws of Cupid, a voice rubbed raw by the philosopher's stone. A voice marinated in kirschwasser, sulfur, deer musk and snow; bandaged with sackcloth from a ruined monastery; warmed by the embers left down near the river after the gypsies have gone. It is a penitent's voice, a rabbinical voice, a crust of unleavened vocal toasts -- spread with smoke and subversive wit. He has a voice like a carpet in an old hotel, like a bad itch on the hunchback of love. It is a voice meant for pronouncing the names of women -- and cataloging their sometimes hazardous charms. Nobody can say the word "naked" as nakedly as Cohen. He makes us see the markings where the pantyhose have been. Finally, the actual persona of their creator may be said to haunt these songs, although details of his private lifestyle can be only surmised. A decade ago, a teacher who called himself Shree Bhagwan Rajneesh came up with the name "Zorba the Buddha" to describe the ideal modern man: A contemplative man who maintains a strict devotional bond with cosmic energies, yet is completely at home in the physical realm. Such a man knows the value of the dharma and the value of the deutschmark, knows how much to tip a waiter in a Paris nightclub and how many times to bow in a Kyoto shrine, a man who can do business when business is necessary, allow his mind to enter a pine cone, or dance in wild abandon if moved by the tune. Refusing to shun beauty, this Zorba the Buddha finds in ripe pleasures not a contradiction but an affirmation of the spiritual self. Doesn't he sound a lot like Leonard Cohen? We have been led to picture Cohen spending his mornings meditating in Armani suits, his afternoons wrestling the muse, his evenings sitting in cafes were he eats, drinks and speaks soulfully but flirtatiously with the pretty larks of the street. Quite possibly this is a distorted portrait. The apocryphal, however, has a special kind of truth. It doesn't really matter. What matters here is that after thirty years, L. Cohen is holding court in the lobby of the whirlwind, and that giants have gathered to pay him homage. To him -- and to us -- they bring the offerings they have hammered from his iron, his lead, his nitrogen, his gold.
Tom Robbins
It is one of the striking generalizations of biochemistry—which surprisingly is hardly ever mentioned in the biochemical text-books—that the twenty amino acids and the four bases, are, with minor reservations, the same throughout Nature. As far as I am aware the presently accepted set of twenty amino acids was first drawn up by Watson and myself in the summer of 1953 in response to a letter of Gamow's.
Francis Crick
By equating the human experience with data patterns, Dataism undermines our main source of authority and meaning, and heralds a tremendous religious revolution, the like of which has not been seen since the eighteenth century. In the days of Locke, Hume and Voltaire humanists argued that ‘God is a product of the human imagination’. Dataism now gives humanists a taste of their own medicine, and tells them: ‘Yes, God is a product of the human imagination, but human imagination in turn is the product of biochemical algorithms.’ In the eighteenth century, humanism sidelined God by shifting from a deo-centric to a homo-centric world view. In the twenty-first century, Dataism may sideline humans by shifting from a homo-centric to a data-centric view. The
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
When you're the sane brother of a schizophrenic identical twin, the tricky thing about saving yourself is the blood it leaves on your hands--the little inconvenience of the look-alike corpse at your feet. And if you're into both survival of the fittest and being your brother's keeper--if you've promised your dying mother--then say so long to sleep and hello to the middle of the night. Grab a book or a beer. Get used to Letterman's gap-toothed smile of the absurd, or the view of the bedroom ceiling, or the indifference of random selection. Take it from a godless insomniac. Take it from the uncrazy twin--the guy who beat the biochemical rap.
Wally Lamb (I Know This Much Is True)
The fetus is biochemically connected to the mother, and her external, internal, physical, and mental health affect the overall development of the fetus. Stress and depression during pregnancy have been proven to have long-term and even permanent effects on the offspring. Such effects include a vulnerability to chronic anxiety, elevated fear, propensity to addictions, and poor impulse control.
Darius Cikanavicius (Human Development and Trauma: How Childhood Shapes Us into Who We Are as Adults)
AT ANOTHER LOCATION, WE FOUND BARRELS OF CHEMICAL material that was intended for use as biochemical weapons. Everyone talks about there being no weapons of mass destruction in Iraq, but they seem to be referring to completed nuclear bombs, not the many deadly chemical weapons or precursors that Saddam had stockpiled. Maybe the reason is that the writing on the barrels showed that the chemicals came from France and Germany, our supposed Western allies.
Chris Kyle (American Sniper)
Politicians are a bit like musicians, and the instrument they play on is the human emotional and biochemical system. They give a speech, and there is a wave of fear in the country. They tweet, and there is an explosion of hatred.
Yuval Noah Harari (21 Lessons for the 21st Century)
Losing a belief in free will has not made me a fatalist - in fact, it has increased my feelings of freedom. My hopes, fears, and neuroses seem less personal and indelible. There is no telling how much I might change in the future. Just as one wouldn't draw a lasting conclusion about oneself on the basis of a brief experience of indigestion, one needn't do so on a basis of how one has thought or behaved for vast stretches of time in the past. A creative change of inputs to the system - learning new skills, forming new relationships, adopting new habits of attention - may radically transform one's life. Becoming sensitive to the background causes of one's thoughts and feelings can -paradoxically- allow for greater creative control over one's life. This understanding reveals you to be a biochemical puppet, of course, but it also allows you to grab hold of one of your strings.
Sam Harris (Free Will)
When trying to understand the interactions of nonhuman organisms, it is easy to flip between these two perspectives: that of the inanimate behavior of preprogrammed robots on the one hand, and that of rich, lived human experience on the other. Framed as brainless organisms, lacking the basic apparatus required to have even a simple kind of “experience,” fungal interactions are no more than automatic responses to a series of biochemical triggers. Yet the mycelium of truffle fungi, like that of most fungal species, actively senses and responds to its surroundings in unpredictable ways.
Merlin Sheldrake (Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures)
Depression and anxiety are two of the body’s first reactions to stockpiles of hurt. Of course, there are organic and biochemical reasons we experience clinical depression and debilitating anxiety—causes over which we have no control—but unrecognized pain and unprocessed hurt can also lead there.
Brené Brown (Rising Strong: The Reckoning. The Rumble. The Revolution.)
Social psychologist argued that even severe mental illness was the result of society labeling unusual behavior rather than of biochemical processes.
Thomas J. Scheff
Creatures with poorly self-regulated stress reactions will be more anxious, less capable of confronting ordinary environmental challenges, and overstressed even under normal circumstances. The study showed the quality of early maternal care to have a causal impact on the offspring’s brains’ biochemical capacity to respond to stress in a healthy way into adulthood. Key
Gabor Maté (The Myth of Normal: Trauma, Illness, and Healing in a Toxic Culture)
The result of these cumulative efforts to investigate the cell—to investigate life at the molecular level—is a loud, clear, piercing cry of “design!” The result is so unambiguous and so significant that it must be ranked as one of the greatest achievements in the history of science. The discovery rivals those of Newton and Einstein, Lavoisier and Schrödinger, Pasteur, and Darwin.
Michael J. Behe (Darwin's Black Box: The Biochemical Challenge to Evolution)
Did I need medication? Or did I need someone to talk to? Someone, that is, who would do more than charge the going rate for nodding and whip out a prescription pad before the first fifty minutes were up. Was I physiologically depressed? At an innate biochemical disadvantage? Or was reaching for the pad just the way things were done because the doc had been well patronized by the drug reps and had plenty of samples in her file cabinet?
Norah Vincent
Even the poorest and most squalid life is an Aeschylean drama, if you think about the tragedy of the bodily functions, the whispering of the secretions, the silence of the organs, the exertions of memory, the groping of the voice, the blood that courses, the mortal miasmas, the riots among microorganisms, the spermatic wars, the cellular eruptions, the pestilences of the nerves, the biochemical predestinations, and the fate that slowly but surely introduces you to the final infection, to the sores, the exploded boils, the snakes of madness, the furious bitches of Hunger.
Guido Ceronetti (The Silence of the Body: Materials for the Study of Medicine)
Thich Nhat Hanh calls his practice of yes “smile yoga.” He suggests bringing a slight but real smile to our lips many times throughout the day, whether we are meditating or simply stopping for a red light. “A tiny bud of a smile on your lips,” writes Thich Nhat Hanh, “nourishes awareness and calms you miraculously … your smile will bring happiness to you and to those around you.” The power of a smile to open and relax us is confirmed by modern science. The muscles used to make a smile actually send a biochemical message to our nervous system that it is safe to relax the flight, fight or freeze response. A smile is the yes of unconditional friendliness that welcomes experience without fear.
Tara Brach (Radical Acceptance: Embracing Your Life with the Heart of a Buddha)
The essential point of view advanced here is this: the stability of every living being, as of every structurally stable form, rests, in the last analysis, on a for- mal structure—in fact, a geometrical object—whose biochemical realization is the living being.
René Thom (Morphogenèse et imaginaire (Circé) (French Edition))
And I'll go even further and say that mathematics, this art of abstract pattern-making — even more than storytelling, painting, or music - is our most quintessentially human art form. This is what our brains do, whether we like it or not. We are biochemical pattern-recognition machines and mathematics is nothing less than the distilled essence of who we are.
Paul Lockhart (A Mathematician's Lament: How School Cheats Us Out of Our Most Fascinating and Imaginative Art Form)
most up-to-date theories also maintain that sensations and emotions are biochemical data-processing algorithms.
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
At each step biochemical triggers and feedbacks determine which of the alternative developmental pathways among several possibles a group of cells will actually follow.
Arthur Koestler (The Ghost in the Machine)
Running is a form of practiced stoicism. It means teaching your brain and body to be biochemically comfortable in a state of disrepair.
Matthew Inman (The Terrible and Wonderful Reasons Why I Run Long Distances (Volume 5) (The Oatmeal))
what distinguishes us from non-human organisms is that we do not simply react to biochemical impulses; we can transcend them by choosing to interpret them in particular ways.
Kevin Aho (Existentialism: An Introduction)
I have to laugh when people ask me if I do alternative, herbal, acupuncture or holistic medicine. 'No,' I reply. 'We do state-of-the-art medicine. In other words, we find the biochemical, nutritional and environmental causes and cures rather than blindly drugging everything. Sure, herbs are gentler, safer and more physiologic than drugs and holistic medicine attempts to incorporate many diverse modalities, etc. But there is no substitute for finding the underlying biochemical causes and cures. This is real medicine. This is where medicine should and would have been decades ago, if it had not been abducted by the pharmaceutical industry.
Sherry A. Rogers (Detoxify or Die)
There are no detailed Darwinian accounts for the evolution of any fundamental biochemical or cellular system, only a variety of wishful speculations [Article : "In the Details . . . What?"]
James A. Shapiro
Bear in mind that since medications do not fix anything, they allow the underlying problem to continue uncorrected and actually accelerate. Meanwhile, new symptoms and new seemingly unrelated diseases are the inevitable consequence of this biochemical faux pas. Furthermore, drug side effects are the leading cause of death. NSAIDs as an example of only one group of medications, are fatally toxic to thousands of people each year by damaging joints, lungs, kidneys, eyes, hearts, and intestines. And they are covered by insurance. You and your doctor have been screwed into believing every symptom is a deficiency of some drug or surgery. You've been led to believe you have no control, when in truth you're the one who must take control. Unfortunately, the modus operandi in medicine is to find a drug to turn off the damaged part that is producing symptoms.
Sherry A. Rogers (Detoxify or Die)
Work ethic is not a moral virtue that can be cultivated simply by wanting to be a better person. It’s actually a biochemical condition that can be fostered, purposefully, through activity that increases dopamine levels in the brain.
Jane McGonigal (SuperBetter: A Revolutionary Approach to Getting Stronger, Happier, Braver and More Resilient--Powered by the Science of Games)
While conversion of sugars to ethanol is the predominant reaction, it is only one of potentially thousands of biochemical reactions taking place during fermentation. As a result, wine contains trace amounts of a large number of organic acids, esters, sugars, alcohols, and other molecules. Wine is, in fact, one of the most complex of all beverages: the fruit of a soil, climate, and vintage, digested by a fungus through a process guided by the culture, vision, and skill of an individual man or woman.
Neel Burton (The Concise Guide to Wine and Blind Tasting)
the mind with the brain, but they are really very different things. The brain is a material network of neurons, synapses, and biochemicals. The mind is a flow of subjective experiences, such as pain, pleasure, anger, and love. Biologists assume that the brain somehow produces

Even if we accept the view that biochemical imbalances may contribute to depression and suicide, it is a mistake to assume that the biochemical aspect of the problem is entirely within the victim. It is also partly within the physiological makeup of the people around the suicide.
David L. Conroy (Out of the Nightmare: Recovery from Depression and Suicidal Pain)
I feel you're far away,” the man might say. He is observing you, calculating, forming equations he may take to a representative of the patriarchy, such as a doctor, a lawyer, or military official. He is considering physical incarceration and/or biochemical imprisonments such as occur with antidepressants. He is dangerous. This is a juncture where you may smile. This is optional. You might allow your lips to form the ambiguous seductive shape of slow regret. Or let your mouth fill with too much night, incinerated maple leaves and fox teeth. What you mean is, not yet.
Kate Braverman
Classifying depression as an illness serves the psychiatric community and pharmaceutical corporations well; it also soothes the frightened, guilty, indifferent, busy, sadistic, and unschooled. To understand depression as a call for life-changes is not profitable. Stagnation is not a medical term. The 17.5 million Americans diagnosed as suffering a major depression in 1997 were mostly damned. (Psychobiological examinations confuse cause and symptom.) Deficient serotonergic functioning, ventral prefrontal cerebral cortex, dis-inhibition of impulsive-aggressive behavior, blah blah blah: the medical lexicon boils emotion from human being. Go take a drug, the doctor says. Pain is a biochemical phenomenon. Erase all memory.
Antonella Gambotto-Burke (The Eclipse: A Memoir of Suicide)
Adrenaline poisoning,’ one of my doctors had called these surges of anxiety that had troubled me since childhood. The doctors explained that, for reasons they could not understand, my body seemed to think it was in a constant state of danger. One of the specialists my aunt consulted explained earnestly that it was a biochemical leftover from hunter-gatherer days. I’d be all right so long as I rid my bloodstream of the adrenaline load
Deborah Harkness (A Discovery of Witches (All Souls Trilogy, #1))
Now that our marriage is over, I know what love is. It's a trick on the brain, the adrenal glands releasing endorphins. It floods the cells that transmit worry and better sense, drowns them with biochemical bliss. You can know all these things about love, yet it remains irresistible, as beguiling as the floating arms of long sleep.
Amy Tan (The Hundred Secret Senses)
Our tree’s only source of energy is the sun: after light photons stimulate the pigments within the leaf, buzzing electrons line up into an unfathomably long chain and pass their excitement one to the other, moving biochemical energy across the cell to the exact location where it is needed. The plant pigment chlorophyll is a large molecule, and within the bowl of its spoon-shaped structure sits one single precious magnesium atom. The amount of magnesium needed for enough chlorophyll to fuel thirty-five pounds of leaves is equivalent to the amount of magnesium found in fourteen One A Day vitamins, and it must ultimately dissolve out of bedrock, which is a geologically slow process.
Hope Jahren (Lab Girl)
Some scientists thrive on the conceptual; their minds can envision particles that the most powerful microscopes can’t show us; processes that can’t be directly observed, but only inferred, guessed at, by interpreting a stew of complex biochemical by-products. I am not one of these scientists; I need bones and teeth, things I can see with my eyes and grasp with my hands. Jason Eshleman, on the other hand, can see with his mind’s eye, grasping the complex interactions of the most complex molecules in the body, DNA.
William M. Bass (Beyond the Body Farm: A Legendary Bone Detective Explores Murders, Mysteries, and the Revolution in Forensic Science)
Maybe someday breakthroughs in neurobiology will enable us to explain communism and the crusades in strictly biochemical terms. Yet we are very far from that point.
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
The recent recognition that the genetic code possesses a unique capacity to resist errors caused by mutation imparts the biochemical intelligent design argument with an entirely new level of credibility. Like a giant SOS shaped with letters ablaze, the optimal nature of the genetic code signals that an Intelligent Agent used those rules to start and sustain life.
Fazale Rana (The Cell's Design (Reasons to Believe): How Chemistry Reveals the Creator's Artistry)
Mind, in the way I use the word, is not just thought. It includes your emotions as well as all unconscious mental-emotional reactive patterns. Emotion arises at the place where mind and body meet. It is the body’s reaction to your mind — or you might say, a reflection of your mind in the body. For example, an attack thought or a hostile thought will create a buildup of energy in the body that we call anger. The body is getting ready to fight. The thought that you are being threatened, physically or psychologically, causes the body to contract, and this is the physical side of what we call fear. Research has shown that strong emotions even cause changes in the biochemistry of the body. These biochemical changes represent the physical or material aspect of the emotion. Of course, you are not usually conscious of all your thought patterns, and it is often only through watching your emotions that you can bring them into awareness.
Eckhart Tolle (The Power of Now: A Guide to Spiritual Enlightenment)
[In reference to cases of testicular feminization]: “The incredible lesson about our sexual biology is that all men at one point in their fetal development have the capacity to be women. Moreover the body is programmed to develop as a female unless it sees and recognizes specific biochemical signals such as testosterone and anti-mullerian factor that tell it to develop as a male.
Abraham Morgentaler (Why Men Fake It: The Totally Unexpected Truth About Men and Sex)
AI will have to analyze human feelings accurately in order to treat human illnesses, identify human terrorists, recommend human mates, and navigate a street full of human pedestrians. But it could do so without having any feelings of its own. An algorithm does not need to feel joy, anger, or fear in order to recognize the different biochemical patterns of joyful, angry, or frightened apes.
Yuval Noah Harari (21 Lessons for the 21st Century)
To try to make a man, you would have to work at your biochemical cocktail-shaker for a period so long that the entire age of the universe would seem like an eye-blink, and even then you would not succeed.
Richard Dawkins (The Selfish Gene)
I find it hard to understand the mind of the true atheist, who believes that life is nothing more than a series of electrical impulses and biochemical reactions to chemical stimuli. Presumably, such thinkers see death as the worst thing that can occur, because it means the end of everything. Therefore (logically), maintaining the continuance of physical existence, under any circumstances, is entirely justifiable.
Jennifer Worth (In the Midst of Life)
Furthermore, because silicon packs on more protons than carbon, it's bulkier, like carbon with fifty extra pounds. Sometimes that's not a big deal. Silicon might substitute adequately for carbon in the Martian equivalent of fats or proteins. But carbon also contorts itself into ringed molecules we call sugars. Rings are states of high-tension- which means they store lots of energy-and silicon just isn't supple enough to bend into the right position to form rings. In a related problem, silicon atoms cannot squeeze their electrons into tight spaces for double bonds, which appear in virtually every complicated biochemical.
Sam Kean (The Disappearing Spoon: And Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements)
Throughout the human life span there remains a constant two-way interaction between psychological states and the neurochemistry of the frontal lobes, a fact that many doctors do not pay enough attention to. One result is the overreliance on medications in the treatment of mental disorders. Modern psychiatry is doing too much listening to Prozac and not enough listening to human beings; people’s life histories should be given at least as much importance as the chemistry of their brains. The dominant tendency is to explain mental conditions by deficiencies of the brain’s chemical messengers, the neurotransmitters. As Daniel J. Siegel has sharply remarked, “We hear it said everywhere these days that the experience of human beings comes from their chemicals.” Depression, according to the simple biochemical model, is due to a lack of serotonin — and, it is said, so is excessive aggression. The answer is Prozac, which increases serotonin levels in the brain. Attention deficit is thought to be due in part to an undersupply of dopamine, one of the brain’s most important neurotransmitters, crucial to attention and to experiencing reward states. The answer is Ritalin. Just as Prozac elevates serotonin levels, Ritalin or other psychostimulants are thought to increase the availability of dopamine in the brain’s prefrontal areas. This is believed to increase motivation and attention by improving the functioning of areas in the prefrontal cortex. Although they carry some truth, such biochemical explanations of complex mental states are dangerous oversimplifications — as the neurologist Antonio Damasio cautions: "When it comes to explaining behavior and mind, it is not enough to mention neurochemistry... The problem is that it is not the absence or low amount of serotonin per se that “causes” certain manifestations. Serotonin is part of an exceedingly complicated mechanism which operates at the level of molecules, synapses, local circuits, and systems, and in which sociocultural factors, past and present, also intervene powerfully. The deficiencies and imbalances of brain chemicals are as much effect as cause. They are greatly influenced by emotional experiences. Some experiences deplete the supply of neurotransmitters; other experiences enhance them. In turn, the availability — or lack of availability — of brain chemicals can promote certain behaviors and emotional responses and inhibit others. Once more we see that the relationship between behavior and biology is not a one-way street.
Gabor Maté (Scattered: How Attention Deficit Disorder Originates and What You Can Do About It)
If these biochemical phenomena sound similar to those of the fight-or-flight syndrome, they are, except that here we are running toward something or someone; indeed, a cynic might say toward rather than away from danger. The changes are also fully consistent with those of the early phases of addictive behavior. The Roxy Music song “Love Is the Drug” is quite accurate in describing this state (albeit the subject of the song is looking to score his next fix of love).
Ray Kurzweil (How to Create a Mind: The Secret of Human Thought Revealed)
The bodies state of red alert brings about a series of psychological changes, driven by gathering tides of adrenaline or cortisol. These are the fight or flight hormones, which act to help and organism respond to external stresses. But when a stress is chronic not acute, when it persists for years and is caused by something that cannot be outrun, then these biochemical alterations wreak havoc on the body. Lonely people are restless sleepers and experience a reduction in the restorative function of sleep. Loneliness drives up blood pressure, accelerates ageing, weakens the immune system and acts as a precursor to cognitive decline. According to a 2010 study, "Loneliness predicts increased morbidity and mortality". Which is an elegant way of saying that loneliness can prove fatal.
Olivia Laing (The Lonely City: Adventures in the Art of Being Alone)
many abuse victims don’t wish to let their abusers move onto the next victim after terrorizing them, because they fear that the next person might be treated better, thereby confirming their own sense of worthlessness that was instilled by the abuser in the first place. They may also have an unending sense of needing a real “apology” or seeing karma at work before they feel they can truly let go.
Shahida Arabi (Your Brain on Love, Sex and the Narcissist: The Biochemical Bonds That Keep Us Addicted to Our Abusers)
Because we are not powerless biochemical machines, popping a pill every time we are mentally or physically out of tune is not the answer. Drugs and surgery are powerful tools when they are not overused, but the notion of simple drug fixes is fundamentally flawed. Every time a drug is introduced into the body to correct function A, it inevitably throws off function B, C, or D. It is not gene-directed hormones and neurotransmitters that control our bodies and our minds; our beliefs control our bodies, our minds, and thus our lives … Oh ye of little belief!
Bruce H. Lipton (The Biology of Belief: Unleasing the Power of Consciousness, Matter and Miracles)
The problem is a survivor never knows when the next warm and fuzzy experience will happen, or when the next episode of abuse is coming through the door. Intermittent reinforcement is a powerful emotional string abusers like to pull. Never knowing what will happen next can be intoxicating for a survivor who is not fully aware of the game being played. Intermittent reinforcement causes adrenaline rushes in the body and stress hormones to be produced. It creates a biochemical shift in the survivor that becomes addicting and from which is hard to break free.
Shannon Thomas (Healing from Hidden Abuse: A Journey Through the Stages of Recovery from Psychological Abuse)
In recent decades life scientists have demonstrated that emotions are not some mysterious spiritual phenomenon that is useful just for writing poetry and composing symphonies. Rather, emotions are biochemical algorithms that are vital for the survival and reproduction of all mammals.
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
This Buddhist view of happiness has a lot in common with the biochemical view. Both agree that pleasant sensations disappear as fast as they arise, and that as long as people crave pleasant sensations without actually experiencing them, they remain dissatisfied. However, this problem has two very different solutions. The biochemical solution is to develop products and treatments that will provide humans with an unending stream of pleasant sensations, so we will never be without them. The Buddha’s suggestion was to reduce our craving for pleasant sensations, and not allow them to control our lives. According to Buddha, we can train our minds to observe carefully how all sensations constantly arise and pass. When the mind learns to see our sensations for what they are – ephemeral and meaningless vibrations – we lose interest in pursuing them. For

there is a hidden intelligence embedded in the female fertility cycle: an ancient knowledge that women can use to make the best decisions in their modern lives. Behind the everyday behavior that some interpret as simply “hormonal,” there is a biochemical process that has helped females—billions across thousands of species—choose mates, avoid rape, compete with female rivals, fight for resources, and produce offspring with fit genes and good prospects. To master these challenges, female brains evolved to conspire with their hormones rather than be corrupted by them.
Martie Haselton (Hormonal: The Hidden Intelligence of Hormones -- How They Drive Desire, Shape Relationships, Influence Our Choices, and Make Us Wiser)
Dataism adopts a strictly functional approach to humanity, appraising the value of human experiences according to their function in data-processing mechanisms. If we develop an algorithm that fulfils the same function better, human experiences will lose their value. Thus if we can replace not just taxi drivers and doctors but also lawyers, poets and musicians with superior computer programs, why should we care if these programs have no consciousness and no subjective experiences? If some humanist starts adulating the sacredness of human experience, Dataists would dismiss such sentimental humbug. ‘The experience you praise is just an outdated biochemical algorithm. In the African savannah 70,000 years ago, that algorithm was state-of-the-art. Even in the twentieth century it was vital for the army and for the economy. But soon we will have much better algorithms.

The mind cannot differentiate between past, present and future events with regards to imagery in the mind. If you attached enough emotional context and feeling to what you are playing in your minds eye I.e. a past memory or projected future event, the body elicits exactly the same biochemical response, as if that experience was happening right now. It’s a clever trick which can convince the mind into believing that you have already achieved these things. The subconscious will then go to work in serving up additional and similar opportunities to bring into your physical reality.

In the days of Locke, Hume and Voltaire humanists argued that ‘God is a product of the human imagination’. Dataism now gives humanists a taste of their own medicine, and tells them: ‘Yes, God is a product of the human imagination, but human imagination in turn is just the product of biochemical algorithms.

Science finds it hard to decipher the mysteries of the mind largely because we lack efficient tools. Many people, including many scientists, tend to confuse the mind with the brain, but they are really very different things. The brain is a material network of neurons, synapses, and biochemicals. The mind is a flow of subjective experiences, such as pain, pleasure, anger, and love. Biologists assume that the brain somehow produces the mind and that biochemical reactions in billions of neurons somehow produce experiences such as pain and love. However, so far we have absolutely no explanation for how the mind emerges from the brain.

The result will not be an Orwellian police state. We always prepare ourselves for the previous enemy, even when we face an altogether new menace. Defenders of human individuality stand guard against the tyranny of the collective, without realising that human individuality is now threatened from the opposite direction. The individual will not be crushed by Big Brother; it will disintegrate from within. Today corporations and governments pay homage to my individuality, and promise to provide medicine, education and entertainment customised to my unique needs and wishes. But in order to so, corporations and governments first need to break me up into biochemical subsystems, monitor these subsystems with ubiquitous sensors and decipher their working with powerful algorithms. In the process, the individual will transpire to be nothing but a religious fantasy. Reality will be a mesh of biochemical and electronic algorithms, without clear borders, and without individual hubs.

Becoming sensitive to the background causes of one's thoughts and feelings can—paradoxically—allow for greater creative control over one's life. It is one thing to bicker with your wife because you are in a bad mood; it is another to realize that your mood and behavior have been caused by low blood sugar. This understanding reveals you to be a biochemical puppet, of course, but it also allows you to grab hold of one of your strings: A bit of food may be all that your personality requires. Getting behind our concious thoughts and feelings can allow us to steer a more intelligent course through our lives (while knowing, of course, that we are ultimately being steered).
Sam Harris (Free Will)
There are simply several different paths leading to high intelligence, and only some of these paths involve gaining consciousness. Just as airplanes fly faster than birds without ever developing feathers, so computers may come to solve problems much better than mammals without ever developing feelings. True, AI will have to analyse human feelings accurately in order to treat human illnesses, identify human terrorists, recommend human mates and navigate a street full of human pedestrians. But it could do so without having any feelings of its own. An algorithm does not need to feel joy, anger or fear in order to recognise the different biochemical patterns of joyful, angry or frightened apes.

Some air-conditioning systems are set at 70 degrees Fahrenheit. Others are set at twenty degrees. Human happiness conditioning systems also differ from person to person. On a scale from one to ten, some people are born with a cheerful biochemical system that allows their mood to swing between levels six and ten, stabilising with time at eight. Such a person is quite happy even if she lives in an alienating big city, loses all her money in a stock-exchange crash and is diagnosed with diabetes. Other people are cursed with a gloomy biochemistry that swings between three and seven and stabilises at five. Such an unhappy person remains depressed even if she enjoys the support of a tight-knit community, wins millions in the lottery and is as healthy as an Olympic athlete.

We now know that early stress and adversity can literally get under a child’s skin, where it can cause damage that lasts a lifetime. But there is also some positive news in this research. It turns out that there is a particularly effective antidote to the ill effects of early stress, and it comes not from pharmaceutical companies or early-childhood educators but from parents. Parents and other caregivers who are able to form close, nurturing relationships with their children can foster resilience in them that protects them from many of the worst effects of a harsh early environment. This message can sound a bit warm and fuzzy, but it is rooted in cold, hard science. The effect of good parenting is not just emotional or psychological, the neuroscientists say; it is biochemical.

Organisms are Algorithms How can we be sure that animals such as pigs actually have a subjective world of needs, sensations and emotions? Aren’t we guilty of humanising animals, i.e. ascribing human qualities to non-human entities, like children believing that dolls feel love and anger? In fact, attributing emotions to pigs doesn’t humanise them. It ‘mammalises’ them. For emotions are not a uniquely human quality – they are common to all mammals (as well as to all birds and probably to some reptiles and even fish). All mammals evolved emotional abilities and needs, and from the fact that pigs are mammals we can safely deduce that they have emotions.16 In recent decades life scientists have demonstrated that emotions are not some mysterious spiritual phenomenon that is useful just for writing poetry and composing symphonies. Rather, emotions are biochemical algorithms that are vital for the survival and reproduction of all mammals. What does this mean? Well, let’s begin by explaining what an algorithm is. This is of great importance not only because this key concept will reappear in many of the following chapters, but also because the twenty-first century will be dominated by algorithms. ‘Algorithm’ is arguably the single most important concept in our world. If we want to understand our life and our future, we should make every effort to understand what an algorithm is, and how algorithms are connected with emotions. An algorithm is a methodical set of steps that can be used to make calculations, resolve problems and reach decisions. An algorithm isn’t a particular calculation, but the method followed when making the calculation.

The three conditions without which healthy growth does not take place can be taken for granted in the matrix of the womb: nutrition, a physically secure environment and the unbroken relationship with a safe, ever-present maternal organism. The word matrix is derived from the Latin for “womb,” itself derived from the word for “mother.” The womb is mother, and in many respects the mother remains the womb, even following birth. In the womb environment, no action or reaction on the developing infant’s part is required for the provision of any of his needs. Life in the womb is surely the prototype of life in the Garden of Eden where nothing can possibly be lacking, nothing has to be worked for. If there is no consciousness — we have not yet eaten of the Tree of Knowledge — there is also no deprivation or anxiety. Except in conditions of extreme poverty unusual in the industrialized world, although not unknown, the nutritional needs and shelter requirements of infants are more or less satisfied. The third prime requirement, a secure, safe and not overly stressed emotional atmosphere, is the one most likely to be disrupted in Western societies. The human infant lacks the capacity to follow or cling to the parent soon after being born, and is neurologically and biochemically underdeveloped in many other ways. The first nine months or so of extrauterine life seem to have been intended by nature as the second part of gestation. The anthropologist Ashley Montagu has called this phase exterogestation, gestation outside the maternal body. During this period, the security of the womb must be provided by the parenting environment. To allow for the maturation of the brain and nervous system that in other species occurs in the uterus, the attachment that was until birth directly physical now needs to be continued on both physical and emotional levels. Physically and psychologically, the parenting environment must contain and hold the infant as securely as she was held in the womb. For the second nine months of gestation, nature does provide a near-substitute for the direct umbilical connection: breast-feeding. Apart from its irreplaceable nutritional value and the immune protection it gives the infant, breast-feeding serves as a transitional stage from unbroken physical attachment to complete separation from the mother’s body. Now outside the matrix of the womb, the infant is nevertheless held close to the warmth of the maternal body from which nourishment continues to flow. Breast-feeding also deepens the mother’s feeling of connectedness to the baby, enhancing the emotionally symbiotic bonding relationship. No doubt the decline of breast-feeding, particularly accelerated in North America, has contributed to the emotional insecurities so prevalent in industrialized countries. Even more than breast-feeding, healthy brain development requires emotional security and warmth in the infant’s environment. This security is more than the love and best possible intentions of the parents. It depends also on a less controllable variable: their freedom from stresses that can undermine their psychological equilibrium. A calm and consistent emotional milieu throughout infancy is an essential requirement for the wiring of the neurophysiological circuits of self-regulation. When interfered with, as it often is in our society, brain development is adversely affected.
Gabor Maté (Scattered: How Attention Deficit Disorder Originates and What You Can Do About It)
Anything perceived as a threat trips the amygdala—the brain’s hand-wringing sentry—to set in motion the biochemical cascade known as the fight-or-flight response. Bruce Siddle, who consults in this area and sits on the board of Strategic Operations, prefers the term “survival stress response.” Whatever you wish to call it, here is a nice, concise summary, courtesy of Siddle: “You become fast, strong, and dumb.” Our hardwired survival strategy evolved back when threats took the form of man-eating mammals, when hurling a rock superhumanly hard or climbing a tree superhumanly fast gave you the edge that might keep you alive. A burst of adrenaline prompts a cortisol dump to the bloodstream. The cortisol sends the lungs into overdrive to bring in more oxygen, and the heart rate doubles or triples to deliver it more swiftly. Meanwhile the liver spews glucose, more fuel for the feats at hand. To get the goods where the body assumes they’re needed, blood vessels in the large muscles of the arms and legs dilate, while vessels serving lower-priority organs (the gut, for example, and the skin) constrict. The prefrontal cortex, a major blood guzzler, also gets rationed. Good-bye, reasoning and analysis. See you later, fine motor skills. None of that mattered much to early man. You don’t need to weigh your options in the face of a snarling predator, and you don’t have time.
Mary Roach (Grunt: The Curious Science of Humans at War)
The cloning of human genes allowed scientists to manufacture proteins-and the synthesis of proteins opened the possibility of targeting the millions of biochemical reactions in the human body. Proteins made it possible for chemists to intervene on previously impenetrable aspects of our physiology. The use of recombinant DNA to produce proteins thus marked a transition not just between one gene and one medicine, but between genes and a novel universe of drugs.
Siddhartha Mukherjee (The Gene: An Intimate History)
Twin, family, and population studies have all conclusively shown that psychological traits are at least partly, and sometimes largely, heritable—that is, a sizable portion of the variation that we see in these traits across the population is attributable to genetic variation. However, as we have seen in the preceding chapters, the relationship between genes and traits is far from simple. The fact that a given trait is heritable seems to suggest that there must be genes for that trait. But phrasing it in that way is a serious conceptual trap. It implies that genes exist that are dedicated to that function—that there are genes for intelligence or sociability or visual perception. But this risks confusing the two meanings of the word gene: one, from the study of heredity, refers to genetic variants that affect a trait; the other, from molecular biology, refers to the stretches of DNA that encode proteins with various biochemical or cellular functions.

How come when billions of neurons are firing electrical signals in a particular pattern, I feel pain, and when the neurons fire in a different pattern, I feel love? We haven’t got a clue. Hence even if the mind indeed emerges from the brain, at least for now studying the mind is a different undertaking than studying the brain.

Just consider the next thought that pops up in your mind. Where did it come from? Did you freely choose to think it, and only then did you think it? Certainly not. The process of self-exploration begins with simple things, and becomes progressively harder. At first, we realise that we do not control the world outside us. I don’t decide when it rains. Then we realise that we do not control what’s happening inside our own body. I don’t control my blood pressure. Next, we understand that we don’t even govern our brain. I don’t tell the neurons when to fire. Ultimately we should realise that we do not control our desires, or even our reactions to these desires. Realising this can help us become less obsessive about our opinions, about our feelings, and about our desires. We don’t have free will, but we can be a bit more free from the tyranny of our will. Humans usually give so much importance to their desires that they try to control and shape the entire world according to these desires. In pursuit of their cravings, humans fly to the moon, wage world wars, and destabilise the entire ecosystem. If we understand that our desires are not the magical manifestations of free choice, but rather are the product of biochemical processes (influenced by cultural factors that are also beyond our control), we might be less preoccupied with them. It is better to understand ourselves, our minds and our desires rather than try to realise whatever fantasy pops up in our heads.

Along with unemployment neurosis, which is triggered by an individual's socioeconomic situation, there are other types of depression which are traceable back to psychodynamic or biochemical conditions, whichever the case may be. Accordingly, psychotherapy and pharmacotherapy are indicated respectively. Insofar as the feeling of meaninglessness is concerned, however, we should not overlook and forget that, per se, it is not a matter of pathology; rather than being the sign and symptom of a neurosis, it is, I would say, the proof of one's humanness. But although it is not caused by anything pathological, it may well cause a pathological reaction; in other words, it is potentially pathogenic. Just consider the mass neurotic syndrome so pervasive in the young generation: there is ample empirical evidence that the three facets of this syndrome - depression, aggression, addiction - are due to what is called in logotherapy "the existential vacuum," a feeling of emptiness and meaninglessness.

If the social stress is physical, sexual, or emotional abuse, the way to treat the depression is to stop the abuse. Unfortunately, advocates of the biochemical treatment of depression have gone along with the view of academic theory and popular culture that the problem is entirely within the skull of the victim. Enthusiasm for biochemical treatment and research is partly due to the fact that it helps perpetuate the myth that suicide and depression should be treated by changing the victim, not by changing ourselves. As long as we have a narrow view of the causes of biochemical imbalance, such as limiting it to innate genetic defects, we can practice denial on the social complicity in the causation of suicide. The narrow view does nothing to help reduce pain and increase resources for the millions of people whose problems do not respond to medications. It also deprives us of an opportunity for progress in a much broader area for social reform. The dynamics behind the oppression of the suicidal is similar to the dynamics of other forms of injustice; progress in one area can support progress in other areas.

Listen, Google,’ I will say, ‘both John and Paul are courting me. I like both of them, but in a different way, and it’s so hard to make up my mind. Given everything you know, what do you advise me to do?’ And Google will answer: ‘Well, I know you from the day you were born. I have read all your emails, recorded all your phone calls, and know your favourite films, your DNA and the entire history of your heart. I have exact data about each date you went on, and if you want, I can show you second-by-second graphs of your heart rate, blood pressure and sugar levels whenever you went on a date with John or Paul. If necessary, I can even provide you with accurate mathematical ranking of every sexual encounter you had with either of them. And naturally enough, I know them as well as I know you. Based on all this information, on my superb algorithms, and on decades’ worth of statistics about millions of relationships – I advise you to go with John, with an 87 per cent probability of being more satisfied with him in the long run. Indeed, I know you so well that I also know you don’t like this answer. Paul is much more handsome than John, and because you give external appearances too much weight, you secretly wanted me to say “Paul”. Looks matter, of course; but not as much as you think. Your biochemical algorithms – which evolved tens of thousands of years ago in the African savannah – give looks a weight of 35 per cent in their overall rating of potential mates. My algorithms – which are based on the most up-to-date studies and statistics – say that looks have only a 14 per cent impact on the long-term success of romantic relationships. So, even though I took Paul’s looks into account, I still tell you that you would be better off with John.

The earliest modern attempt to test prayer’s efficacy was Sir Francis Galton’s innovative but flawed survey in 1872.16 The field languished until the 1960s, when several researchers began clinical and laboratory studies designed to answer two fundamental questions: (1) Do the prayerful, compassionate, healing intentions of humans affect biological functions in remote individuals who may be unaware of these efforts? (2) Can these effects be demonstrated in nonhuman processes, such as microbial growth, specific biochemical reactions, or the function of inanimate objects? The answer to both questions appears to be yes.

This is an existential threat to the social and economic order, which is why countries wage a stubborn, bloody and hopeless war on biochemical crime. The state hopes to regulate the biochemical pursuit of happiness, separating ‘bad’ manipulations from ‘good’ ones. The principle is clear: biochemical manipulations that strengthen political stability, social order and economic growth are allowed and even encouraged (e.g., those that calm hyperactive kids in school, or drive anxious soldiers forward into battle). Manipulations that threaten stability and growth are banned. But each year new drugs are born in the research labs of universities, pharmaceutical companies and criminal organisations, and the needs of the state and the market also keep changing.

To sum up: at various stages of embryonic development, and at various structural levels, we find different biochemical mechanisms, but analogue principles at work. At every stage and level the game is played according to fixed rules but with flexible strategies (although their flexibility is normally hidden from the eye and revealed only by the transplantation and grafting techniques of experimental embryology). The overall rules of the game are laid down in the complete set of instructions operative at any level at any time is triggered off by messages from the inter- and extra-cellular environment, which vary in character according to structural level and developmental stage: fertilizing agents, cytoplasmic feedbacks, direct-contact evocators, hormones, and other catalysts.

This should have stopped the schizophrenogenic voodoo right in its tracks. High blood pressure can be lessened with a drug that blocks a receptor for a different type of neurotransmitter, and you conclude that a core problem was too much of that neurotransmitter. But schizophrenic symptoms can be lessened with a drug that blocks dopamine receptors, and you still conclude that the core problem is toxic mothering. Remarkably, that’s what psychiatry’s psychoanalytic ruling class concluded. After fighting the introduction of the medications tooth and nail in America and eventually losing, they came up with an accommodation: neuroleptics weren’t doing anything to the core problems of schizophrenia; they just sedated patients enough so that it is easier to psychodynamically make progress with them about the scars from how they were mothered. The psychoanalytic scumbags even developed a sneering, pejorative term for families (i.e., mothers) of schizophrenic patients who tried to dodge responsibility by believing that it was a brain disease: dissociative-organic types. The influential 1958 book Social Class and Mental Illness: A Community Study (John Wiley), by the Viennese psychiatrist Frederick Redlich, who chaired Yale’s psychiatry department for seventeen years, and the Yale sociologist August Hollingshead, explained it all. Dissociative-organic types were typically lower-class, less educated people, for whom “It’s a biochemical disorder” was akin to still believing in the evil eye, an easy, erroneous explanation for those not intelligent enough to understand Freud. Schizophrenia was still caused by lousy parenting, and nothing was to change in the mainstream for decades.

Nobody is ever made happy by winning the lottery, buying a house, getting a promotion or even finding true love. People are made happy by one thing and one thing only – pleasant sensations in their bodies. A person who just won the lottery or found new love and jumps from joy is not really reacting to the money or the lover. She is reacting to various hormones coursing through her bloodstream and to the storm of electric signals flashing between different parts of her brain. Unfortunately for all hopes of creating heaven on earth, our internal biochemical system seems to be programmed to keep happiness levels relatively constant. There's no natural selection for happiness as such - a happy hermit's genetic line will go extinct as the genes of a pair of anxious parents get carried on to the next generation. Happiness and misery play a role in evolution only to the extent that they encourage or discourage survival and reproduction. Perhaps it's not surprising, then, that evolution has moulded us to be neither too miserable nor too happy. It enables us to enjoy a momentary rush of pleasant sensations, but these never last for ever. Sooner of later they subside and give place to unpleasant sensations. (...)

There is only one historical development that has real significance. Today, when we finally realise that the keys to happiness are in the hands of our biochemical system, we can stop wasting our time on politics and social reforms, putsches and ideologies, and focus instead on the only thing that can make us truly happy: manipulating our biochemistry. If we invest billions in understanding our brain chemistry and developing appropriate treatments, we can make people far happier than ever before, without any need of revolutions. Prozac, for example, does not change regimes, but by raising serotonin levels it lifts people out of their depression. Nothing captures the biological argument better than the famous New Age slogan: ‘Happiness begins within.’ Money, social status, plastic surgery, beautiful houses, powerful positions – none of these will bring you happiness. Lasting happiness comes only from serotonin, dopamine and oxytocin.1 In Aldous Huxley’s dystopian novel Brave New World, published in 1932 at the height of the Great Depression, happiness is the supreme value and psychiatric drugs replace the police and the ballot as the foundation of politics. Every day, each person takes a dose of ‘soma’, a synthetic drug which makes people happy without harming their productivity and efficiency. The World State that governs the entire globe is never threatened by wars, revolutions, strikes or demonstrations, because all people are supremely content with their current conditions, whatever they may be. Huxley’s vision of the future is far more troubling than George Orwell’s Nineteen Eighty-Four. Huxley’s world seems monstrous to most readers, but it is hard to explain why. Everybody is happy all the time – what could be wrong with that?

By equating the human experience with data patterns, Dataism undermines our main source of authority and meaning, and heralds a tremendous religious revolution, the like of which has not been seen since the eighteenth century. In the days of Locke, Hume and Voltaire humanists argued that ‘God is a product of the human imagination’. Dataism now gives humanists a taste of their own medicine, and tells them: ‘Yes, God is a product of the human imagination, but human imagination in turn is the product of biochemical algorithms.’ In the eighteenth century, humanism sidelined God by shifting from a deo-centric to a homo-centric world view. In the twenty-first century, Dataism may sideline humans by shifting from a homo-centric to a data-centric view. The Dataist revolution will probably take a few decades, if not a century or two. But then the humanist revolution too did not happen overnight. At first, humans kept on believing in God, and argued that humans are sacred because they were created by God for some divine purpose. Only much later did some people dare say that humans are sacred in their own right, and that God doesn’t exist at all. Similarly, today most Dataists say that the Internet-of-All-Things is sacred because humans are creating it to serve human needs. But eventually, the Internet-of-All-Things may become sacred in its own right.

The humanities, in contrast, emphasise the crucial importance of intersubjective entities, which cannot be reduced to hormones and neurons. To think historically means to ascribe real power to the contents of our imaginary stories. Of course, historians don’t ignore objective factors such as climate changes and genetic mutations, but they give much greater importance to the stories people invent and believe. North Korea and South Korea are so different from one another not because people in Pyongyang have different genes to people in Seoul, or because the north is colder and more mountainous. It’s because the north is dominated by very different fictions. Maybe someday breakthroughs in neurobiology will enable us to explain communism and the crusades in strictly biochemical terms. Yet we are very far from that point. During the twenty-first century the border between history and biology is likely to blur not because we will discover biological explanations for historical events, but rather because ideological fictions will rewrite DNA strands; political and economic interests will redesign the climate; and the geography of mountains and rivers will give way to cyberspace. As human fictions are translated into genetic and electronic codes, the intersubjective reality will swallow up the objective reality and biology will merge with history. In the twenty-first century fiction might thereby become the most potent force on earth, surpassing even wayward asteroids and natural selection. Hence if we want to understand our future, cracking genomes and crunching numbers is hardly enough. We must also decipher the fictions that give meaning to the world.

Listen, Google,’ I will say, ‘both John and Paul are courting me. I like both of them, but in different ways, and it’s so hard to make up my mind. Given everything you know, what do you advise me to do?’ And Google will answer: ‘Well, I’ve known you from the day you were born. I have read all your emails, recorded all your phone calls, and know your favourite films, your DNA and the entire biometric history of your heart. I have exact data about each date you went on and, if you want, I can show you second-by-second graphs of your heart rate, blood pressure and sugar levels whenever you went on a date with John or Paul. If necessary, I can even provide you with an accurate mathematical ranking of every sexual encounter you had with either of them. And naturally, I know them as well as I know you. Based on all this information, on my superb algorithms, and on decades’ worth of statistics about millions of relationships –I advise you to go with John, with an 87 per cent probability that you will be more satisfied with him in the long run. ‘Indeed, I know you so well that I also know you don’t like this answer. Paul is much more handsome than John, and because you give external appearances too much weight, you secretly wanted me to say “Paul”. Looks matter, of course; but not as much as you think. Your biochemical algorithms –which evolved tens of thousands of years ago on the African savannah –give looks a weight of 35 per cent in their overall rating of potential mates. My algorithms –which are based on the most up-to-date studies and statistics –say that looks have only a 14 per cent impact on the long-term success of romantic relationships. So, even though I took Paul’s looks into account, I still tell you that you would be better off with John.

All addictions — whether to drugs or to nondrug behaviours — share the same brain circuits and brain chemicals. On the biochemical level the purpose of all addictions is to create an altered physiological state in the brain. This can be achieved in many ways, drug taking being the most direct. So an addiction is never purely “psychological” all addictions have a biological dimension. And here a word about dimensions. As we delve into the scientific research, we need to avoid the trap of believing that addiction can be reduced to the actions of brain chemicals or nerve circuits or any other kind of neurobiological, psychological or sociological data. A multilevel exploration is necessary because it’s impossible to understand addiction fully from any one perspective, no matter how accurate. Addiction is a complex condition, a complex interaction between human beings and their environment. We need to view it simultaneously from many different angles — or, at least, while examining it from one angle, we need to keep the others in mind. Addiction has biological, chemical, neurological, psychological, medical, emotional, social, political, economic and spiritual underpinnings — and perhaps others I haven’t thought about. To get anywhere near a complete picture we must keep shaking the kaleidoscope to see what other patterns emerge. Because the addiction process is too multifaceted to be understood within any limited framework, my definition of addiction made no mention of “disease.” Viewing addiction as an illness, either acquired or inherited, narrows it down to a medical issue. It does have some of the features of illness, and these are most pronounced in hardcore drug addicts like the ones I work with in the Downtown Eastside. But not for a moment do I wish to promote the belief that the disease model by itself explains addiction or even that it’s the key to understanding what addiction is all about. Addiction is “all about” many things. Note, too, that neither the textbook definitions of drug addiction nor the broader view we’re taking here includes the concepts of physical dependence or tolerance as criteria for addiction. Tolerance is an instance of “give an inch, take a mile.” That is, the addict needs to use more and more of the same substance or engage in more and more of the same behaviour, to get the same rewarding effects. Although tolerance is a common effect of many addictions, a person does not need to have developed a tolerance to be addicted.

REPROGRAMMING MY BIOCHEMISTRY A common attitude is that taking substances other than food, such as supplements and medications, should be a last resort, something one takes only to address overt problems. Terry and I believe strongly that this is a bad strategy, particularly as one approaches middle age and beyond. Our philosophy is to embrace the unique opportunity we have at this time and place to expand our longevity and human potential. In keeping with this health philosophy, I am very active in reprogramming my biochemistry. Overall, I am quite satisfied with the dozens of blood levels I routinely test. My biochemical profile has steadily improved during the years that I have done this. For boosting antioxidant levels and for general health, I take a comprehensive vitamin-and-mineral combination, alpha lipoic acid, coenzyme Q10, grapeseed extract, resveratrol, bilberry extract, lycopene, silymarin (milk thistle), conjugated linoleic acid, lecithin, evening primrose oil (omega-6 essential fatty acids), n-acetyl-cysteine, ginger, garlic, l-carnitine, pyridoxal-5-phosphate, and echinacea. I also take Chinese herbs prescribed by Dr. Glenn Rothfeld. For reducing insulin resistance and overcoming my type 2 diabetes, I take chromium, metformin (a powerful anti-aging medication that decreases insulin resistance and which we recommend everyone over 50 consider taking), and gymnema sylvestra. To improve LDL and HDL cholesterol levels, I take policosanol, gugulipid, plant sterols, niacin, oat bran, grapefruit powder, psyllium, lecithin, and Lipitor. To improve blood vessel health, I take arginine, trimethylglycine, and choline. To decrease blood viscosity, I take a daily baby aspirin and lumbrokinase, a natural anti-fibrinolytic agent. Although my CRP (the screening test for inflammation in the body) is very low, I reduce inflammation by taking EPA/DHA (omega-3 essential fatty acids) and curcumin. I have dramatically reduced my homocysteine level by taking folic acid, B6, and trimethylglycine (TMG), and intrinsic factor to improve methylation. I have a B12 shot once a week and take a daily B12 sublingual. Several of my intravenous therapies improve my body’s detoxification: weekly EDTA (for chelating heavy metals, a major source of aging) and monthly DMPS (to chelate mercury). I also take n-acetyl-l-carnitine orally. I take weekly intravenous vitamins and alpha lipoic acid to boost antioxidants. I do a weekly glutathione IV to boost liver health. Perhaps the most important intravenous therapy I do is a weekly phosphatidylcholine (PtC) IV, which rejuvenates all of the body’s tissues by restoring youthful cell membranes. I also take PtC orally each day, and I supplement my hormone levels with DHEA and testosterone. I take I-3-C (indole-3-carbinol), chrysin, nettle, ginger, and herbs to reduce conversion of testosterone into estrogen. I take a saw palmetto complex for prostate health. For stress management, I take l-theonine (the calming substance in green tea), beta sitosterol, phosphatidylserine, and green tea supplements, in addition to drinking 8 to 10 cups of green tea itself. At bedtime, to aid with sleep, I take GABA (a gentle, calming neuro-transmitter) and sublingual melatonin. For brain health, I take acetyl-l-carnitine, vinpocetine, phosphatidylserine, ginkgo biloba, glycerylphosphorylcholine, nextrutine, and quercetin. For eye health, I take lutein and bilberry extract. For skin health, I use an antioxidant skin cream on my face, neck, and hands each day. For digestive health, I take betaine HCL, pepsin, gentian root, peppermint, acidophilus bifodobacter, fructooligosaccharides, fish proteins, l-glutamine, and n-acetyl-d-glucosamine. To inhibit the creation of advanced glycosylated end products (AGEs), a key aging process, I take n-acetyl-carnitine, carnosine, alpha lipoic acid, and quercetin.
