Now evolution works, in large part, through variation and natural selection.
But there’s an additional question lurking under the surface: what exactly is the “nature” in “natural selection”? What exactly is “the environment” to which animals adapt?
Mark Twain once said, “It’s not what we don’t know that gets us in trouble. It’s what we know for sure that just ain’t so.”
The environment—the nature that selects—itself transforms. The famous yin and yang symbols of the Taoists capture this beautifully. Being, for the Taoists—reality itself—is composed of two opposing principles, often translated as feminine and masculine, or even more narrowly as female and male. However, yin and yang are more accurately understood as chaos and order. The Taoist symbol is a circle enclosing twin serpents, head to tail. The black serpent, chaos, has a white dot in its head. The white serpent, order, has a black dot in its head. This is because chaos and order are interchangeable,

Nature “selects.” The idea of selects contains implicitly nested within it the idea of fitness. It is “fitness” that is “selected.” Fitness, roughly speaking, is the probability that a given organism will leave offspring (will propagate its genes through time). The “fit” in “fitness” is therefore the matching of organismal attribute to environmental demand.
The still-powerful Victorian idea of evolutionary progress, with man at the pinnacle, is a partial consequence of this model of nature. It produces the erroneous notion that there is a destination of natural selection (increasing fitness to the environment), and that it can be conceptualized as a fixed point. But nature, the selecting agent, is not a static selector—not in any simple sense. Nature dresses differently for each occasion.
As the environment supporting a species transforms and changes, the features that make a given individual successful in surviving and reproducing also transform and change.
It is more that creatures are in a dance with nature, albeit one that is deadly. “In my kingdom,” as the Red Queen tells Alice in Wonderland, “you have to run as fast as you can just to stay in the same place.” No one standing still can triumph, no matter how well constituted.
Nature is not simply dynamic, either. Some things change quickly, but they are nested within other things that change less quickly (music frequently models this, too). Leaves change more quickly than trees, and trees more quickly than forests. Weather changes faster than climate. If it wasn’t this way, then the conservatism of evolution would not work, as the basic morphology of arms and hands would have to change as fast as the length of arm bones and the function of fingers. It’s chaos, within order, within chaos, within higher order. The order that is most real is the order that is most

Eco-activists, even more idealistic in their viewpoint, envision nature as harmoniously balanced and perfect, absent the disruptions and depredations of mankind. Unfortunately, “the environment” is also elephantiasis and guinea worms (don’t ask), anopheles mosquitoes and malaria, starvation-level droughts, AIDS and the Black Plague. We don’t fantasize about the beauty of these aspects of nature, although they are just as real as their Edenic counterparts.
If Mother Nature wasn’t so hell-bent on our destruction, it would be easier for us to exist in simple harmony with her dictates.
And this brings us to a third erroneous concept: that nature is something strictly segregated from the cultural constructs that have emerged within it.
The order within the chaos and order of Being is all the more “natural” the longer it has lasted. This is because “nature” is “what selects,” and the longer a feature has existed the mor...

and the dominance hierarchy, however social or cultural it might appear, has been around for some half a billion years. It’s permanent. It’s real.
The part of our brain that keeps track of our position in the dominance hierarchy is therefore exceptionally ancient and fundamental.17 It is a master control system, modulating our perceptions, values, emotions, thoughts and actions. It powerfully affects every aspect of our Being, conscious and unconscious
Consider serotonin, the chemical that governs posture and escape in the lobster. Low-ranking lobsters produce comparatively low levels of serotonin. This is also true of low-ranking human beings (and those low levels decrease more with each defeat). Low serotonin means decreased confidence. Low serotonin means more response to stress and costlier physical preparedness for emergency—as anything whatsoever may happen, at any time, at the bottom of the dominance hierarchy (and rarely something good). Low serotonin means less happiness, more pain and anxiety, more illness, and a shorter

Higher spots in the dominance hierarchy, and the higher serotonin levels typical of those who inhabit them, are characterized by less illness, misery and death, even when factors such as absolute income—or number of decaying food scraps—are held constant. The importance of this can hardly be overstated.
There is an unspeakably primordial calculator, deep within you, at the very foundation of your brain, far below your thoughts and feelings. It monitors exactly where you are positioned in society—on a scale of one to ten, for the sake of argument.
The ancient part of your brain specialized for assessing dominance watches how you are treated by other people. On that evidence, it renders a determination of your value and assigns you a status. If you are judged by your peers as of little worth, the counter restricts serotonin availability.
Unfortunately, that physical hyper-response, that constant alertness, burns up a lot of precious energy and physical resources. This response is really what everyone calls stress, and it is by no means only or even primarily psychological. It’s a reflection of the genuine constraints of unfortunate circumstances. When operating at the bottom, the ancient brain counter assumes that even the smallest unexpected impediment might produce an uncontrollable chain of negative events, which will have to be handled alone, as useful friends are rare indeed, on society’s fringes. You will therefore

It will render you impulsive,20 so that you will jump, for example, at any short-term mating opportunities, or any possibilities of pleasure, no matter how sub-par, disgraceful or illegal. It will leave you far more likely to live, or die, carelessly, for a rare opportunity at pleasure, when it manifests itself. The physical demands of emergency preparedness will wear you down in every way.21
If you have a high status, on the other hand, the counter’s cold, pre-reptilian mechanics assume that your niche is secure, productive and safe, and that you are well buttressed with social support. It thinks the chance that something will damage you is low and can be safely discounted. Change might be opportunity, instead of disaster. The serotonin flows plentifully. This renders you confident and calm, standing tall and straight, and much less on constant alert. Because your position is secure, the future is likely to be good for you. It’s worthwhile to think in the long term and plan for a

The acts of life we repeat every day need to be automatized. They must be turned into stable and reliable habits, so they lose their complexity and gain predictability and simplicity.
It is for such reasons that I always ask my clinical clients first about sleep. Do they wake up in the morning at approximately the time the typical person wakes up, and at the same time every day? If the answer is no, fixing that is the first thing I recommend. It doesn’t matter so much if they go to bed at the same time each evening, but waking up at a consistent hour is a necessity. Anxiety and depression cannot be easily treated if the sufferer has unpredictable daily routines.
The next thing I ask about is breakfast. I counsel my clients to eat a fat and protein-heavy breakfast as soon as possible after they awaken (no simple carbohydrates, no sugars, as they are digested too rapidly, and produce a blood-sugar spike and rapid dip). This is because anxious and depressed people are already stressed, particularly if their lives have not been under control for a good while. Their bodies are therefore primed to hypersecrete insulin, if they engage in any complex or demanding activity. If they do so after fasting all night and before eating, the excess insulin in their

A positive feedback loop requires an input detector, an amplifier, and some form of output. Imagine a signal picked up by the input detector, amplified, and then emitted, in amplified form. So far, so good. The trouble starts when the input detector detects that output, and runs it through the system again, amplifying and emitting it again. A few rounds of intensification and things get dangerously out of control. Most people have been subject to the deafening howling of feedback at a concert, when the sound system squeals painfully.
Addiction to alcohol or another mood-altering drug is a common positive-feedback process.
When he stops, not only does his blood alcohol level plateau and then start to sink, but his body begins to produce a variety of toxins, as it metabolizes the ethanol already consumed. He also starts to experience alcohol withdrawal, as the anxiety systems that were suppressed during intoxication start to hyper-respond. A hangover is alcohol withdrawal (which quite frequently kills withdrawing alcoholics), and it starts all too soon after drinking ceases.
The next day, the drinker wakes up, badly hungover. So far, this is just unfortunate. The real trouble starts when he discovers that his hangover can be “cured” with a few more drinks the morning after.
When the medication causes the disease, a positive feedback loop has been established.
Some real event typically precipitates the initial increase in fear of mortality and social judgment.24
The agoraphobic will even eventually become afraid of her house, and would run away from that if she could. But she can’t. Soon she’s stuck in her home. Anxiety-induced retreat makes everything retreated from more anxiety-inducing. Anxiety-induced retreat makes the self smaller and the ever-more-dangerous world larger.
There are many systems of interaction between brain, body and social world that can get caught in positive feedback loops. Depressed people, for example, can start feeling useless and burdensome, as well as grief-stricken and pained. This makes them withdraw from contact with friends and family. Then the withdrawal makes them more lonesome and isolated, and more likely to feel useless and burdensome. Then they withdraw more. In this manner, depression spirals and amplifies.
This often happens in the case of people, now adults, who were viciously bullied during childhood or adolescence. They become anxious and easily upset. They shield themselves with a defensive crouch, and avoid the direct eye contact interpretable as a dominance challenge. This means that the damage caused by the bullying (the lowering of status and confidence) can continue, even after the bullying has ended.25 In the simplest of cases, the formerly lowly persons have matured and moved to new and more successful places in their lives. But they don’t fully notice. Their now-counterproductive

Sometimes people are bullied because they can’t fight back. This can happen to people who are weaker, physically, than their opponents.
But just as often, people are bullied because they won’t fight back. This happens not infrequently to people who are by temperament compassionate and self-sacrificing—particularly if they are also high in negative emotion, and make a lot of gratifying noises of suffering when someone sadistic confronts them
It also happens to people who have decided, for one reason or another, that all forms of aggression, including even feelings of anger, are morally wrong.
People who refuse to muster appropriately self-protective territorial responses are laid open to exploitation as much as those who genuinely can’t stand up for their own rights because of a more essential inability or a true imbalance in power.
Many bureaucracies have petty authoritarians within them, generating unnecessary rules and procedures simply to express and cement power. Such people produce powerful undercurrents of resentment around them which, if expressed, would limit their expression of pathological power. It is in this manner that the willingness of the individual to stand up for him or herself protects everyone from the corruption of society.
A profound example of that can be found in the susceptibility of new soldiers to post-traumatic stress disorder, which often occurs because of something they watch themselves doing, rather than because of something that has happened to them.
When the wakening occurs—when once-naïve people recognize in themselves the seeds of evil and monstrosity, and see themselves as dangerous (at least potentially)— their fear decreases. They develop more self-respect. Then, perhaps, they begin to resist oppression.
There is very little difference between the capacity for mayhem and destruction, integrated, and strength of character. This is one of the most difficult lessons of life.
If you slump around, with the same bearing that characterizes a defeated lobster, people will assign you a lower status, and the old counter that you share with crustaceans, sitting at the very base of your brain, will assign you a low dominance number. Then your brain will not produce as much serotonin. This will make you less happy, and more anxious and sad, and more likely to back down when you should stand up for yourself. It will also decrease the probability that you will get to live in a good neighbourhood, have access to the highest quality resources, and obtain a healthy, desirable

Positive feedback loops, adding effect to effect, can spiral counterproductively in a negative direction, but can also work to get you ahead. That’s the other, far more optimistic lesson of Price’s law and the Pareto distribution: those who start to have will probably get more.
If you are asked to move the muscles one by one into a position that looks happy, you will report feeling happier. Emotion is partly bodily expression, and can be amplified (or dampened) by that expression.
People, like lobsters, size each other up, partly in consequence of stance. If you present yourself as defeated, then people will react to you as if you are losing. If you start to straighten up, then people will look at and treat you differently.
Standing up physically also implies and invokes and demands standing up metaphysically. Standing up means voluntarily accepting the burden of Being. Your nervous system responds in an entirely different manner when you face the demands of life voluntarily. You respond to a challenge, instead of bracing for a catastrophe.
To stand up straight with your shoulders back is to accept the terrible responsibility of life, with eyes wide open. It means deciding to voluntarily transform the chaos of potential into the realities of habitable order. It means adopting the burden of self-conscious vulnerability, and accepting the end of the unconscious paradise of childhood, where finitude and mortality are only dimly comprehended. It means willingly undertaking the sacrifices necessary to generate a productive and meaningful reality (it means acting to please God, in the ancient language).
So, attend carefully to your posture. Quit drooping and hunching around. Speak your mind. Put your desires forward, as if you had a right to them—at least the same right as others. Walk tall and gaze forthrightly ahead. Dare to be dangerous. Encourage the serotonin to flow plentifully through the neural pathways desperate for its calming influence.
