Will Creates Difference, Which Creates Problems

Working notes, not prose. This page is a research packet for drafting the chapter: the brief, source material, questions, examples, reader perspectives, and the earlier draft.

Brief

Must: Show many creatures wanting in the same ecosystem, with examples at different scales (cells, animals, people, groups), and use those wants to explain behavior in the layered way Sapolsky does, from the pull of the moment down to the history that shaped it.
Serves: It fills the world with players and shows behavior as wants meeting other wants: the conflict half of how players relate.

“A behavior has occurred—one that is reprehensible, or wonderful, or floating ambiguously in between. What occurred in the prior second that triggered the behavior? This is the province of the nervous system. What occurred in the prior seconds to minutes that triggered the nervous system to produce that behavior? This is the world of sensory stimuli, much of it sensed unconsciously. What occurred in the prior hours to days to change the sensitivity of the nervous system to such stimuli? Acute actions of hormones. And so on, all the way back to the evolutionary pressures played out over the prior millions of years that started the ball rolling.” — Robert Sapolsky, Behave: The Biology of Humans at Our Best and Worst (2017), ch. 1 “The Behavior”, opening paragraph. [verified: https://web.stanford.edu/class/cs379c/resources/inverted/content/Books_and_Journal_Articles_on_Consciousness/Behave_Biology_of_Humans_Best_and_Worst_Sapolsky/Behave_Biology_of_Humans_Best_and_Worst_Sapolsky.txt] Why: The layered, second-to-millennia explanation of behavior that the outline asks the chapter to model; can be trimmed to the first three sentences for an epigraph.
“Take any demand, however slight, which any creature, however weak, may make. Ought it not, for its own sole sake, to be satisfied? If not, prove why not. The only possible kind of proof you could adduce would be the exhibition of another creature who should make a demand that ran the other way.” — William James, “The Moral Philosopher and the Moral Life” (1891), in The Will to Believe (1897). [verified: https://monadnock.net/james/moral-life.html] Why: Every want counts, and a want is only checked by another creature’s opposing want. That is the chapter’s thesis in four sentences.
“The actually possible in this world is vastly narrower than all that is demanded; and there is always a pinch between the ideal and the actual which can only be got through by leaving part of the ideal behind. There is hardly a good which we can imagine except as competing for the possession of the same bit of space and time with some other imagined good.” — William James, “The Moral Philosopher and the Moral Life” (1891), in The Will to Believe (1897). [verified: https://monadnock.net/james/moral-life.html] Why: Names why difference becomes a problem: wants compete for the same limited space and time.
“But the struggle almost invariably will be most severe between the individuals of the same species, for they frequent the same districts, require the same food, and are exposed to the same dangers.” — Charles Darwin, On the Origin of Species (1859, 1st ed.), ch. III “Struggle for Existence”. [verified: https://www.gutenberg.org/cache/epub/1228/pg1228.txt] Why: Many creatures wanting in the same ecosystem: the closer the wants, the sharper the conflict. It works at every scale the chapter covers.
“We must know that war is common to all and strife is justice, and that all things come into being and pass away (?) through strife.” — Heraclitus, fr. 62 Bywater (DK B80), trans. John Burnet, Early Greek Philosophy (3rd ed., 1920), ch. 3. The ”(?)” is Burnet’s own mark of doubt. [verified: https://libarynth.org/fragments_of_heraclitus] Why: Heraclitus is already in the chapter’s references, and this is the oldest version of “wants meeting wants” as the engine of the world.

Research

Core argument

Pick up where Chapter 1 left off. A someone is whatever wants something. But a world with one wanter in it has no plot. Once you grant that wanting makes a character, you have to grant that the world is crowded with characters: cells, microbes, plants, animals, people, families, firms, nations.
All these wants share one room. They draw on the same space, time, food, light, mates and attention. Darwin’s point, already among the chapter’s quotes, is that the fiercest competition happens between the most similar wanters, because they want the same things. Difference in direction matters less than you’d think. What turns difference into a problem is overlap in what is wanted.
Wanting creates difference. A want is a direction, and a direction divides the world into “toward” and “away,” “mine” and “not mine,” “helps” and “gets in the way.” Two wanters in one place divide the same world differently, so they experience different worlds. (Keep the earlier draft’s window scene: one situation, two directions.)
Conflict turns up at every scale, and inside what looks like one player. Cancer cells cheat on the body’s cooperative contract. Genes from a mother and from a father pull a fetus’s growth in opposite directions. Baboon mothers and infants fight over weaning. Siblings fight over food. Boys at a summer camp form hostile tribes within days. Nations argue over who counts. Each level also contains conflict among its own parts, so no “individual” is perfectly unified. (This sets up Chapter 5’s cut between me and world.)
Explaining behavior means layering wants over time, as Sapolsky does. Choose one act, such as a slammed window or a shove on a bus, and walk it backward: the second before (neural firing), minutes before (what was seen and heard), hours before (hormones, hunger, sleep), months before (neural plasticity, stress), childhood, the womb, genes, culture and centuries, evolution. At every layer the question is the same: whose wants, meeting whose, shaped this? A want is never one thing. It has a history of other wants inside it.
Most conflict isn’t malice. It is want against want under scarcity. The Robbers Cave boys were chosen to be alike, and competition for prizes was enough to make them enemies. Hardin’s herders aren’t villains. Each one is acting reasonably. That makes conflict structural and easier to predict, though no easier to excuse.
Structure isn’t destiny, and this limit has to be said. Ostrom shows that people sharing a commons often write their own rules and avoid the tragedy. Axelrod’s tournaments show cooperation arising from repeated encounters. Minimal groups show that which wants we treat as opposed is partly a matter of labels. Conflict is the default pressure, not the only outcome. That hands the other half of the story to Chapter 3.
Difference is also information. A clash shows where an arrangement fails to fit everyone who has to live in it (the earlier draft makes this point). Without friction there is nothing to notice, compare or revise.
Close on the human twist. Other creatures’ wants mostly collide over matter: food, space, mates. Ours also collide over representations: flags, names, stories, who is “Us.” This foreshadows Act II’s information world and the Act I close, where volition is what makes us unnatural.

Key questions

If everything that wants is a character, how many characters are in a single square metre of soil? In one human body?
Is a cancer cell “wanting” anything, or are we projecting? At what point does talk of a cell’s want stop being a metaphor?
Why do the most similar creatures fight hardest? Why is a sibling more of a rival than a stranger?
Can two wants be incompatible without either party being wrong or bad?
When a mother baboon slaps her whining toddler away from the nipple, who is “right”?
If maternal and paternal genes in the same fetus pull in opposite directions, is a person one player or a negotiated settlement?
Explaining a single behavior, how far back do you have to go before the explanation feels complete? Does it ever?
If every behavior has causes going back millions of years, where does blame go? (Sapolsky’s own answer is radical: he denies free will. The author should decide whether to follow him.)
What turns a mere difference into a problem? Is it scarcity, overlap, proximity, or a story about the other?
Why did 22 boys who had been chosen to be as alike as possible become enemies within a week?
How little does it take to make an “Us”? (Tajfel: a preference for Klee over Kandinsky.)
Is conflict between groups just conflict between individuals scaled up, or does something new emerge at the level of the group?
When everyone acts reasonably and the outcome is ruin (the commons), whose want caused the problem?
Is the absence of conflict a sign of health, or of one side winning so thoroughly that it no longer registers as conflict?
“The strong do what they can”: is power just a want with more resources behind it?
Can a want ever be judged except by pointing at another creature’s opposing want (James’s challenge)?
What is the difference between competing for the same thing and wanting opposite things?
Do plants have conflicts? A tree shading out its neighbour, a walnut poisoning the soil: is that wanting, or just chemistry?
Are humans the only creatures whose wants can collide over symbols (a flag, a name, a slur)?
If difference always creates problems, why would anyone want a world with more difference in it?

Examples

The window (from the earlier draft). One room, one open window. One person wants air to concentrate. Another, cold by the oven, keeps shutting it. Use it as the everyday baseline and as the running exercise. It also works as a miniature Sapolsky layering: the second before (a shiver), hours before (a poor night’s sleep, a cold coming on), years before (growing up in a house where heating cost money).
Cancer as a cheating cell. Aktipis et al. (2015) describe multicellularity as cooperation among cells and cancer as “cheating” on it. They identify “five foundations of multicellularity” that tumours break: proliferation inhibition, cell death, division of labour, resource allocation, and maintenance of the extracellular environment. Cancer-like phenomena appear across the tree of life, in plants and fungi as well as animals. PubMed 26056363
Social amoebae and the stalk. When food runs out, Dictyostelium discoideum cells aggregate into a fruiting body. Some become a dead stalk so that others can become spores and disperse. “Cheater” strains avoid the stalk and crowd into the spores. Medina et al. (2024) found that chimeric bodies with cheaters have shorter stalks and disperse worse, a built-in cost to cheating. Wanting at the scale of a single cell, with a group-level consequence. PubMed 38562996
The tug-of-war inside a pregnancy. David Haig’s theory of genomic imprinting holds that paternally expressed genes push for more fetal growth while maternally expressed genes push back. In mice, paternal Igf2 is a growth factor and maternal Igf2r soaks it up. Sapolsky calls it “an arms race” inside one fetus. As of 2019 about 260 imprinted genes had been reported in mice and 228 in humans (Wikipedia: Genomic imprinting). Source: Haig, “Genetic conflicts in human pregnancy,” Quarterly Review of Biology 68 (1993); Sapolsky, Behave, ch. 10.
Weaning conflict in baboons. Robert Trivers’s theory of parent–offspring conflict (American Zoologist 14, 1974) predicts that an offspring wants more investment than the parent is selected to give. Sapolsky describes baboon toddlers whimpering and trying to nurse while frazzled mothers push them off. While nursing, a mother is unlikely to ovulate, so each extra feed costs her future children. Older mothers wean less forcefully. (Behave, ch. 10, “Parent-Offspring Conflict”)
Siblicide in eagles. In Aquila eagles, the older chick often kills the younger. Biologists explain the second egg as “insurance” for the parents. The two chicks and the parents want different things from the same nest. Wikipedia: Verreaux’s eagle / Siblicide
The cuckoo and the reed warbler. A brood parasite’s want (to have its chick raised) runs directly against the host’s want (to raise its own). The result is an evolutionary arms race of egg mimicry and egg rejection. It is conflict between species, carried out inside one nest.
Wolves and elk in Yellowstone. The last wolves in Yellowstone were killed in 1926. Wolves were reintroduced to the Lamar Valley in 1995. Wolves now kill about 22 elk per wolf per year, against an earlier estimate of 12. Some ecologists argue that elk behaviour changed too (a “landscape of fear”). Others dispute how strong that effect is, which makes this a good caveat case about tidy ecological stories. Wikipedia: History of wolves in Yellowstone
The Gombe Four-Year War (1974–1978). Jane Goodall watched the Kasakela chimpanzee community split. Six adult males, three adult females and their young broke away as the Kahama community. Over four years, Kasakela males killed the Kahama males one by one. Former groupmates became “Them.” Sapolsky notes that chimp groups that grow large may divide, and “murderous animosities soon emerge between ex-groupmates.” Wikipedia; Behave, ch. 11.
Robbers Cave (1954). Muzafer and Carolyn Wood Sherif took 22 eleven- and twelve-year-old boys to Robbers Cave State Park, Oklahoma. The boys were chosen for similar backgrounds and split into two groups (the “Rattlers” and the “Eagles”). Competition for prizes produced raids, flag-burning and name-calling. Tension eased only when the boys faced “superordinate goals” that needed both groups. Caveat: Gina Perry’s The Lost Boys (2018) documents manipulation by the experimenters and an earlier failed 1953 version. Wikipedia: Realistic conflict theory
The minimal group paradigm. Henri Tajfel (Bristol, around 1970–71) sorted schoolboys by a trivial preference, supposedly for Klee or Kandinsky paintings. The boys then gave more money to their own group, even when that meant their group got less in absolute terms. Here the wants are manufactured by a label. Wikipedia: Minimal group paradigm; Tajfel, “Experiments in intergroup discrimination,” Scientific American 223 (1970).
Us/Them in fifty milliseconds. Sapolsky reports that a fifty-millisecond glimpse of a face of another race activates the amygdala. Monkeys also look longer at pictures that pair their own group with spiders. The division happens before thought, which ties back to Chapter 1’s “before thought, there is want.” (Behave, ch. 11)
The commons, and how it avoids tragedy. Hardin (1968) imagines herders on a shared pasture, each gaining from one more animal while all pay the cost. Ostrom’s counter-cases include Törbel, Switzerland, where villagers have managed alpine meadows under written communal rules for centuries (her earliest documents date from the 13th century). Maine lobster “harbor gangs” enforce informal territories. Collective wants can be governed. Ostrom Nobel lecture, 2009; Ostrom, Governing the Commons (1990), ch. 3.
Melos, 416 BCE. Athens demands the neutral island of Melos submit. The Athenian envoys dismiss justice as something that applies only “between equals in power” (Thucydides 5.89). Melos refuses, and Athens kills the men and enslaves the women and children. This is the civilizational scale: wants backed by unequal power. Verified wording (Crawley trans.): “right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must.” [verified: https://www.gutenberg.org/cache/epub/7142/pg7142.txt]
A Sapolsky-style thought experiment: the shove on the bus. A man shoves another passenger. Walk it back layer by layer. One second before: amygdala activation, poor frontal inhibition. Minutes before: someone stood on his foot, and the bus was loud and hot. Hours before: he skipped lunch, and his testosterone and cortisol were high after an argument at work. Months before: he was laid off, with chronic stress. Adolescence: a neighbourhood where not backing down mattered. Childhood: a volatile home. Culture: a “culture of honor” (Sapolsky, Behave, ch. 9). Evolution: status competition among males. Each layer is a want meeting a want. Ask the reader where on this chain they would place responsibility.

Sapolsky on how fast we split into Us and Them.

“Our brains form Us/Them dichotomies (henceforth, “Us/Them-ing,” for brevity) with stunning speed.”

Division between wanters is fast and pre-reflective, not a conclusion anyone reasons their way to.
Sapolsky on the genetic arms race inside a pregnancy.

“It’s an arms race, with Dad genetically egging on his offspring toward more growth at the cost of the female’s future reproductive plans, and Mom genetically countering this with a more balanced reproductive strategy.”

Sapolsky, Behave (2017), ch. 10 “The Evolution of Behavior,” section “Parent-Offspring Conflict.” [verified: same Stanford URL as above] Use: Conflict even inside one body. It unsettles the assumption that a “player” is a single want.
Hobbes on two people wanting the same thing.

“if any two men desire the same thing, which neverthelesse they cannot both enjoy, they become enemies”

Thomas Hobbes, Leviathan (1651), Part I, ch. XIII “Of the Naturall Condition of Mankind.” [verified: https://www.gutenberg.org/cache/epub/3207/pg3207.txt] Use: The clearest one-line statement that overlap in wants, not difference in character, produces enmity. It pairs well with Robbers Cave.
Darwin on the hidden violence of a pleasant scene.

“We behold the face of nature bright with gladness, we often see superabundance of food; we do not see, or we forget, that the birds which are idly singing round us mostly live on insects or seeds, and are thus constantly destroying life”

Charles Darwin, On the Origin of Species (1859, 1st ed.), ch. III “Struggle for Existence.” [verified: https://www.gutenberg.org/cache/epub/1228/pg1228.txt] Use: An opening image. A peaceful garden is full of competing wants that we don’t see. (It differs from the Darwin line already in Quote options.)
Spinoza’s conatus: everything tries to go on.

“Everything, in so far as it is in itself, endeavours to persist in its own being.”

Baruch Spinoza, Ethics (1677), Part III, Proposition VI, trans. R. H. M. Elwes (1883). [verified: https://www.gutenberg.org/cache/epub/3800/pg3800.txt] Use: The minimal philosophical form of “every creature wants.” It bridges from Chapter 1 and explains why a crowded world has to collide.
Schopenhauer on nature as will fighting itself.

“Thus everywhere in nature we see strife, conflict, and alternation of victory, and in it we shall come to recognise more distinctly that variance with itself which is essential to the will. Every grade of the objectification of will fights for the matter, the space, and the time of the others.”

[verified: https://www.gutenberg.org/cache/epub/38427/pg38427.txt] Use: Almost the chapter’s title in 1818 language. Will fights for “the matter, the space, and the time” of other will. It is in the references for Chapter 1 and continues naturally here.
Hegel: a self finds satisfaction only through another self.

“Self-consciousness attains its satisfaction only in another self-consciousness.”

G. W. F. Hegel, The Phenomenology of Mind (1807), B. IV “The True Nature of Self-Certainty,” §175, trans. J. B. Baillie (1910). Just before it: “self-consciousness is Desire.” [verified: https://www.marxists.org/reference/archive/hegel/works/ph/phb.htm] Use: Hegel is in this chapter’s old references. The desiring self needs another desiring self, which is the root of the struggle for recognition (§§178–188, “Lordship and Bondage”). It is a hinge to Chapter 3.
Hardin’s commons.

“Ruin is the destination toward which all men rush, each pursuing his own best interest in a society that believes in the freedom of the commons. Freedom in a commons brings ruin to all.”

Garrett Hardin, “The Tragedy of the Commons,” Science 162 (1968): 1243–1248, at 1244. [verified: https://math.uchicago.edu/~shmuel/Modeling/Hardin,%20Tragedy%20of%20the%20Commons.pdf] Use: The group-scale case where reasonable individual wants add up to shared disaster. Pair it immediately with Ostrom (next) so the chapter doesn’t overstate it.
Ostrom’s reply: people are not trapped.

“Public investigators purposely keep prisoners separated so they cannot communicate. The users of a common-pool resource are not so limited.”

Elinor Ostrom, “Beyond Markets and States: Polycentric Governance of Complex Economic Systems,” Nobel Prize Lecture, 8 December 2009, §4 “Are Rational Individuals Helplessly Trapped in Social Dilemmas?” (Nobel PDF p. 416; reprinted in American Economic Review 100, 2010). [verified: https://www.nobelprize.org/uploads/2018/06/ostrom_lecture.pdf] Use: The main limit on the chapter’s thesis. Conflicting wants are a pressure, not a fate, and talking changes the game.
Cancer as cheating.

“Multicellularity is characterized by cooperation among cells for the development, maintenance and reproduction of the multicellular organism. Cancer can be viewed as cheating within this cooperative multicellular system.”

C. Athena Aktipis et al., “Cancer across the tree of life: cooperation and cheating in multicellularity,” Philosophical Transactions of the Royal Society B 370 (2015): 20140219, abstract. [verified: https://pubmed.ncbi.nlm.nih.gov/26056363/] Use: The cellular scale. Even inside you, parts have “wants” that can defect from the whole.

Counterarguments and limits

Anthropomorphism at small scales. Saying a cell or gene “wants” is shorthand for selection dynamics. A critic will say the chapter smuggles agency into chemistry. Chapter 1’s criterion (a someone is whatever wants) has to hold here, or the chapter should mark the cell cases explicitly as “as-if” wanting. Dennett’s “intentional stance” is a useful, honest framing.
Conflict is overstated; cooperation is at least as fundamental. Margulis (symbiogenesis), Maynard Smith and Szathmáry (major transitions), Kropotkin’s Mutual Aid (1902) and Ostrom all show cooperation building the very players that later compete. If the chapter reads as “nature red in tooth and claw,” it will seem dated. Frame conflict as one half of how players relate, and explicitly hand the other half to Chapter 3.
Sapolsky’s layers lead to his hard determinism. In Determined (2023) Sapolsky argues there is no free will. If the chapter adopts his layered method, readers may assume it also adopts his conclusion. That clashes with the Act I close (“unnatural in volition”). The author must decide how to take the method without the metaphysics.
Famous studies are shakier than their reputation. Robbers Cave has well-documented problems with methods and ethics (Perry 2018). Minimal-group effects are real but smaller and more context-bound than popular accounts suggest. The Yellowstone “trophic cascade” story is contested. Present these as illustrations with caveats, not proofs.
Hobbes and Hardin assume people can’t communicate. Ostrom’s field evidence shows that assumption often fails. Hardin also later conceded he meant an unmanaged commons, and his essay carries troubling population politics. The author may not want to lean on him uncritically.
“Most conflict isn’t malice” can excuse harm. The earlier draft is right that a different perspective doesn’t make harm harmless. Structural explanation isn’t exoneration. Make that explicit.
Evolutionary just-so stories. Explaining a human behavior by “evolutionary pressures millions of years ago” is easy and hard to test. Sapolsky himself warns about this (Behave, ch. 10, on the heritability requirement).
Scale-jumping. Intragenomic conflict, cell cheating, sibling rivalry and war are analogous but not the same mechanism. The chapter should state that the pattern (want meets want under scarcity) is shared and the mechanisms are not.

Connections

Ch. 1 (Before Thought, There Is Want): This chapter multiplies Chapter 1’s single wanter into a crowded ecosystem. Sapolsky’s fifty-millisecond Us/Them response shows want acting before thought.
Ch. 3 (Love, Growth, and Meaning): The explicit other half, where wants take each other in. Ostrom, Axelrod’s tit-for-tat, Robbers Cave’s superordinate goals and Hegel’s recognition are all bridges.
Ch. 4 (Subjectivity): The window scene shows two perspectives on one situation. Us/Them bias previews the filters of body, history and language.
Act I close (Unnatural in Volition): How much of our wanting is shaped by the layers is the tension this close must resolve.
Ch. 5 (The First Blade, Me and World): Cancer and imprinting show that the “me” is itself a negotiated coalition, a system inside systems.
Ch. 6 (Reality and Representation): Human conflicts over flags, names and stories are conflicts in the information world.
Ch. 7 (Good, Bad): Good and bad begin as survival. Here, wants competing for survival come first.
Ch. 9 (The Cost of the Blade) and Ch. 10 (Thingification): Us/Them labels harden into categories that become destiny. The minimal group paradigm is a direct example.
Ch. 18 (Loops That Learn and Loops That Don’t): Arms races (cuckoo and host, imprinting) and escalation (Gombe, Melos) are runaway loops.
Ch. 19 (What Knowledge Needs to Stay Alive): Ideas compete for attention the way organisms compete for resources.
Ch. 20 (Raising the Floor): Hardin and Ostrom set up the book’s collective-life argument and program theory.

Exercise ideas

Layer one collision. Pick one small conflict from the past week in which your want met someone else’s: the window, the last slice, the thermostat, who drives. Write it at the top of a page. Below it, write five rows labelled “one second before,” “an hour before,” “a week before,” “years before,” “before I was born (family, culture).” Fill in each row for yourself, then do the same for the other person as best you can guess. Notice: how many rows of your own you had never thought about, and how much vaguer the other person’s rows are. Why: This is Sapolsky’s layered method applied to a real case. It shows that every want carries a history of other wants, and that we explain ourselves more generously than others.
Count the players in one place. Sit for ten minutes in one spot: a park bench, a kitchen, an office. List every wanter you can identify (birds, insects, plants turning toward light, people, a dog, the business that owns the café, the city that set the parking rules). Next to each, write what it wants and one thing it competes with another listed player for. Notice: how quickly the list grows, and how many conflicts are invisible until you look (Darwin’s “bright with gladness”). Why: It makes the chapter’s claim concrete: the world is crowded with players, and their wants overlap.
Find the overlap, not the difference. Take a disagreement you’re in, personal or political. Write down (a) what each side wants, then (b) what scarce thing both sides actually need: time, money, space, attention, status, safety. Notice: whether the conflict comes from different wants or from the same want for a limited thing (Hobbes, Darwin). Then ask whether a shared goal would change it (Robbers Cave, Ostrom). Why: This separates the chapter’s two ideas, difference and scarcity, and points toward Chapter 3.

Open questions for the author

How literal is “want” for cells and genes? Commit to Chapter 1’s criterion and say cells want, or mark the small scales as “as-if”? This affects the credibility of the whole act.
Sapolsky’s determinism: use his layering while openly disagreeing with Determined, or stay silent on it? The Act I close depends on this.
How dark should the chapter be? It could lean into Hobbes, Schopenhauer and Melos, or keep conflict light and domestic (the window) and save the violence for a few examples.
Keep the window scene as the spine? It is warm and relatable but small. An alternative spine is a single ecosystem (a pond, a garden, a hospital ward) followed across scales.
Where does “difference is information” go? It could stay here, or move to Chapter 4 or Chapter 6 (Bateson’s “a difference that makes a difference”).
Which Hegel? The struggle for recognition is powerful but dense. Use a single line, or give it a full section as the hinge into Chapter 3?
The old references (Simondon, Kauffman, Brian Arthur’s path dependence): keep path dependence as “the history that shaped it” (it fits Sapolsky’s deep layers), or cut it to keep the chapter concrete?
Human uniqueness claim: does the chapter assert that only humans fight over symbols, or leave that for Act II?

Reader perspectives

Curious young child

First reactions:

“Wanting makes problems” is obviously true to anyone with a sibling. Instant buy-in.
The open-window example feels like parents arguing over the thermostat. It’s relatable, but a kid would rather it be about the back seat of the car: one wants the window down, the other’s hair is flying everywhere.
Cells wanting things in the same “ecosystem” sounds amazing, like tiny wars inside your body. They want to hear more.
The part explaining behaviour “from the second before to millions of years ago” is like a rewind button. They love it if it’s a rewind, and are lost if it’s a list.
“Everyone has their own truth is not an answer” makes them think of the grown-up who says “you’re both right” to end a fight. They find that unfair too.

Questions they’d ask:

“If my sister and I both want the last pancake, who’s right?”
“Do my cells fight each other? Who wins?”
“Do germs want to make me sick, or do they just want to eat?”
“Why do lions eat zebras? Doesn’t the zebra want to live too?”
“Why do birds fight over the bird feeder when there’s plenty?”
“Why did I push him? I didn’t decide to, I was just mad.”
“How far back does the rewind go? Does my great-great-grandma make me grumpy?”
“If cavemen made me like snacks, is it their fault I ate all the chips?”
“Why does the kid who’s bigger always get the swing?”
“Can two ant hills have a war?”
“If it’s all because of history, is anyone ever in trouble for real?”
“What’s path dependence? Is that like when you always walk the same way to school and then there’s a trail in the grass?”

Where they’d get lost, bored, offended or unconvinced:

The brief promises cells, animals, people and groups, but the earlier draft only has the window. A kid would feel promised a zoo and handed a kitchen.
The Sapolsky layering is in the brief but not the draft. Without it the chapter misses its best kid-friendly device: “What happened one second before? One minute? This morning? When you were a baby? Before people existed?”
“A direction is, in this modest sense, a small disagreement with the rest of the room” is too abstract. They’d want “wanting different things is like pulling on the same blanket”.
“Precision does not guarantee harmony” goes past them. “Saying exactly what you want doesn’t always fix the fight, but it helps” would land.
“Harm does not become harmless because the person causing it has a different perspective”: they’d strongly agree, and want an example like “He said it was a joke but it still hurt.”
The layered explanation could feel like an excuse (“It’s not my fault, it’s my hormones”). They’d test it straight away, and the chapter should say why explaining is not the same as excusing.

Examples they’d bring:

Cuckoo chicks: a cuckoo chick hatches in another bird’s nest and pushes the other eggs out. Kids find this horrifying and unforgettable. It’s wants meeting wants at their most brutal.
Sharing a bunk bed or back seat: the same small space, two wants: a light on for reading, a light off for sleeping.
Ant colonies: whole groups that act like they want something (food, territory), and can fight other colonies. This is the “groups” scale the brief asks for.
The body’s defence cells chasing bacteria: there’s a famous old microscope film of a white blood cell chasing a bacterium, made by David Rogers at Vanderbilt in the 1950s. The cell scale, made vivid.
Picking teams at recess: everyone wants to be picked, captains want the best players, and someone is always picked last. Wants, power and history all at once.
The grass shortcut across the school field: path dependence in their own words. Everyone walks where the path is worn, so it gets more worn.

What would win them over:

The rewind device, used on one real kid moment (pushing someone at the slide), going back layer by layer.
Being fair about the fight: nobody is a villain just for wanting, and wanting doesn’t make hurting OK.
Weird animal facts at every scale, so “many creatures wanting” feels like a nature documentary.
A practical ending they can use tomorrow: “Say what you want, say what they want, find one thing you both have to deal with.”

Cynical adult

First reactions:

The open-window argument is real life. I’ve had it. It’s also a very small, very polite conflict for a chapter titled “Which Creates Problems.”
The brief promises cells, animals, people and groups, all wanting in one ecosystem, plus Sapolsky’s layered causation. The draft delivers one room with a window. The biggest gap between brief and draft in Act I.
“Everyone has their own truth is not an answer.” Good. That’s the line that tells me the author isn’t going soft.
“Precision does not guarantee harmony. It gives disagreement fewer places to hide.” Best sentence in the chapter.
Path dependence gets one paragraph and a disclaimer. Either it matters or it doesn’t.

Questions they’d ask:

Sapolsky used this layered model to argue in Determined (2023) that there’s no free will at all. Do you agree? Your Act I ends on “near-ultimate freedom,” so you’d better say.
If behavior is explained from the last second back to evolution, where exactly does “want” sit? Is it one layer, or all of them?
Cells “wanting” in the same ecosystem: is a cancer cell a player with a want? Does the metaphor still hold there, or does it break?
The window: who pays the heating bill, and who owns the flat? Isn’t the real conflict about power, not “directions”?
Is conflict actually bad? Markets, courts and science all run on structured disagreement.
“A claim about the open window can still be checked.” Checked by whom? The one who controls the thermostat?
How is this different from “seek first to understand” in Covey’s 7 Habits?
What happens when one want simply has to lose? Does the book have anything for that, or only for the cases where a jumper fixes it?
Does “difference is information” apply to the neighbour who wants to build a wall on my land?
Is path dependence a real explanation of a person, or a borrowed economics metaphor used as a mood?

Where they’d get lost, bored, offended or unconvinced:

Unconvinced: the window scene is too low-stakes to carry “Problems.” A cynic reads the resolution (jumper, extractor fan, time limit) as a fantasy of reasonable housemates. Add one conflict where nothing reasonable works.
Bored: “A direction is a way a situation matters from somewhere.” Abstract restatements of the concrete scene. The scene already did the job.
Unconvinced: the Sapolsky method is named in the brief but never demonstrated. Run it on one real behavior, second by second back to deep time, or the claim that the chapter is “in the layered way Sapolsky does” isn’t true.
Offended (a little): “People and institutions can change, though usually not by being shouted at from the other side of the window.” Someone who has had to shout to be heard (the next chapter talks about whose account gets heard) will read this as tone-policing.
Lost: “direction,” “variation,” “difference,” “individuality” (in the themes), “divergence” (in the subtitle). Which is the key term?
Missing: the Darwin quote (strife is sharpest between those who need the same things) is the chapter’s real engine and a genuinely non-obvious point. The draft never uses it.

Examples they’d bring:

The office thermostat war, with data. Kingma and van Marken Lichtenbelt (2015, Nature Climate Change) argued that standard office temperature formulas were based on the metabolic rate of an average man, which tends to leave many women too cold. The window conflict becomes a case where a “neutral” standard carried one side’s want.
Tragedy of the commons and its rebuttal. Hardin (1968, Science) said shared resources get destroyed by competing wants. Elinor Ostrom’s Governing the Commons (1990) showed many communities managed them for centuries with local rules. The chapter’s whole thesis, with a Nobel attached.
Cancer. Cells in one body whose “wants” (proliferation) diverge from the organism’s. It’s multicellular cooperation breaking down and a vivid cell-scale example of wants meeting wants.
Cuckoos and reed warblers. One species’ want exploiting another’s: the cuckoo chick pushes out the host’s eggs, and host species evolve rejection behaviors. Conflict between species in one ecosystem.
QWERTY keyboards. The standard path-dependence example (Paul David, “Clio and the Economics of QWERTY,” 1985). A cynic will note that Liebowitz and Margolis disputed it (“The Fable of the Keys,” 1990), which makes it a good honesty test for the book.
Divorce and custody. Two wants that both include a child’s good, and still can’t both win. It tests whether “describe it precisely” is enough.

What would win them over:

Actually run the Sapolsky layers on one behavior (a road-rage incident, a teenager’s risky dare), and show where “want” lives in each layer.
Include one conflict with no happy synthesis, and say what the book recommends then.
Take a clear position on Sapolsky’s determinism now, so the Act I close doesn’t look like it’s dodging.
Deliver the scale ladder the brief promises (cell, animal, person, group) with one short, vivid case each.

Believer / spiritual reader

First reactions:

The window argument is the most human, least cosmic scene so far, and believers who live in households and congregations will recognize it at once. Church committee meetings are this chapter.
Heraclitus’s “strife is justice” as an epigraph will unsettle Christian and Buddhist readers, for whom strife is at best a symptom. It will please some Hindu readers (the Gita opens on a battlefield) and Taoists who see opposition as complementarity.
The Sapolsky layering (seconds, hours, years, millennia) pushes toward determinism. Readers with a doctrine of moral responsibility, or of sin and repentance, will worry that the chapter explains away blame. Believers in predestination (Reformed, some Ash’arite Muslims) may find it oddly congenial.
Moved by “Harm does not become harmless because the person causing it has a different perspective.” That is a moral floor they share.
Notices that the draft never mentions forgiveness, which is how most traditions handle wants that collide.

Questions they’d ask:

If behavior is explained all the way back to evolution, where does repentance fit? Can a person turn (teshuvah, metanoia, tawbah) against their layers?
Is conflict built into creation (Heraclitus) or a breakage of it (Genesis 3–4)? The chapter seems to pick the first without saying so.
James says every demand ought to be satisfied unless another demand blocks it. Does God’s demand, or the moral law, count as “another creature’s demand”?
Your answer to the window is a jumper or a fan: management. Where is sacrifice, where one person simply yields out of love?
Who adjudicates between wants when “precision does not guarantee harmony”? Traditions have judges, elders, a Law. What does your book have?
Is “path dependence” a secular word for what Buddhists call karma, the momentum of past action shaping present options?
Cells, animals, people, groups: does the book claim the same logic of conflicting wants runs at every scale? If so, is war between nations just the window writ large?
Is there any want we all share, which would make agreement possible, or are we only ever negotiating?
What about wants that are unjust at their root, like greed and domination? Are they simply more “difference”?
If difference is “information”, is suffering information too? What does that make of the suffering servant, or of the Buddha’s First Noble Truth?

Where they’d get lost, bored, offended or unconvinced:

Unconvinced by “Difference is not a defect we will eventually outgrow.” Eschatological traditions (Isaiah 11:6, the wolf and the lamb; Revelation 21) hope exactly for outgrowing some difference. At least acknowledge that hope as a rival view.
Lost on how the draft’s small household window reaches the brief’s cells-to-groups sweep and Sapolsky layering. The draft has none of the scale examples the brief demands.
Mildly offended by “people and institutions can change, though usually not by being shouted at from the other side of the window” if the only institutions in view are religious ones. Include the church, but not only the church.
Bored by the practice instructions, which read like HR mediation.

Examples they’d bring:

Cain and Abel (Genesis 4): two offerings, one accepted, and wanting becomes murder within a single chapter of the first family. “Sin is crouching at the door; its desire is for you, but you must master it” (Gen 4:7) is the classic text on whether we can govern the pull.
Jacob and Esau struggling in the womb (Gen 25:22–23): conflict before birth, at the smallest scale. A perfect “wants at every scale” image from scripture.
James 4:1: “From whence come wars and fightings among you? come they not hence, even of your lusts that war in your members?” (KJV). Scripture’s own layered account, from inner want to outer war.
Arjuna on the field of Kurukshetra (Bhagavad Gita ch. 1): wanting peace and duty at once, facing kin on the other side. Conflicting wants inside one person and between groups.
The Rule of St Benedict, ch. 3: the abbot must call the whole community to counsel, because “the Lord often reveals what is better to the younger” (RB 3.3). A 6th-century procedure for hearing the less powerful voice in a disagreement.

What would win them over:

An honest section on how traditions have handled clashing wants (law, confession, forgiveness, sabbath and jubilee resets) as working technologies, not superstition.
Allowing repentance or conversion as a real counter-example to path dependence: people do sometimes turn.
Showing at least one scale where wants resolve by self-giving rather than negotiation, which also sets up Chapter 3.

Skeptical scientist

First reactions:

The brief asks for many scales (cells, animals, people, groups). The draft gives one: a window in a kitchen. For a chapter about ecosystems of wanting, there is no ecosystem in it. This is the chapter most in need of real biology.
Sapolsky’s layered explanation is a good model, but it has an older and more rigorous ancestor: Tinbergen’s four questions (mechanism, development, function, evolution). Using Tinbergen would give the chapter a framework biologists recognize and would stop it from mixing proximate and ultimate causes.
The title’s causal arrow is backwards from biology’s view. Difference (variation) comes first; selection among differences produces things that behave as if they want. “Will creates difference” is true at the behavioral level and false at the evolutionary one. Say which.
Be careful importing Sapolsky wholesale. In Determined (2023) he uses the same layered explanation to argue there is no free will. That walks straight into the Act I close claim that we are “unnatural in volition.” The book needs to decide whether it agrees with him.
“A direction is a small disagreement with the rest of the room about what matters now” is a nice line. But the window example is resolved by facts about thermoregulation that the draft doesn’t know it has.

Questions they’d ask:

At the cellular scale, what is the conflict? Cancer cells defecting from the multicellular bargain? Selfish genetic elements? Name one.
When you say wants “meet,” do you mean the game-theoretic sense (payoffs interact) or the ecological one (shared limiting resources)? These have different mathematics.
Is the layered explanation meant to excuse, explain or predict? Sapolsky’s layers are post hoc; can they predict anything?
Does conflict require wanting, or just shared limited resources? Two plants competing for light: is that a conflict of wants?
Is within-species conflict really sharper than between-species, as the Darwin quote says? It is generally true for resource competition, but predator-prey is hardly mild.
How does conflict inside one organism fit: mother versus fetus, parent versus offspring, one gene versus another?
Path dependence: are you using Brian Arthur’s formal model (increasing returns, lock-in) or the loose sense? The QWERTY example often attached to it is disputed.
At the group scale, why don’t commons always collapse? What does Ostrom’s work say that Hardin’s missed?
How do you know the person at the oven is actually cold rather than rationalizing? Is there a physiological basis for the disagreement?
Where in your layered account does culture enter, and how do you separate it from genetics without falling into nature/nurture cliché?

Where they’d get lost, bored, offended or unconvinced:

The window scenario is too domestic and too small to carry “many creatures wanting in the same ecosystem.” A reader expecting the Sapolsky-style tour from seconds to millennia gets a kitchen.
“Difference makes things noticeable… Without variation there is nothing to compare”: true, and exactly where evolution by natural selection belongs. It needs to be named, not implied.
“Everyone has their own truth is not an answer”: fine, but the chapter should show how a disagreement gets partly settled by data. The window case can be (see thermal comfort below).
Path dependence is introduced and then dropped in a paragraph. Either use a real case (lock-in of the VHS standard, or of AC versus DC) or cut it.
Any phrasing like “genes want” or “cells want” will make evolutionary biologists wary unless the chapter says the metaphor is shorthand for “was selected because it produced this.” Dawkins was explicit about that; the book should be too.

Examples they’d bring:

Thermal comfort and sex: Kingma & van Marken Lichtenbelt (2015), Nature Climate Change, “Energy consumption in buildings and female thermal demand,” argued that office temperature standards were based on a metabolic rate typical of a man around 40 and overestimate women’s metabolic rate. The window fight has a measurable physiological layer, which turns the chapter’s example into a Sapolsky-style layered explanation.
Social amoeba cheaters: Strassmann, Zhu & Queller (2000), Nature, showed that in Dictyostelium discoideum some strains over-contribute to spores (which survive) and under-contribute to stalk (which dies). It is conflict inside cooperation at the cellular scale.
Mother-fetus conflict: Haig (1993), Quarterly Review of Biology, “Genetic conflicts in human pregnancy.” The fetus and placenta manipulate maternal blood sugar and blood pressure, and the mother counters. It is wanting against wanting inside one body, with clinical consequences (preeclampsia, gestational diabetes).
Cancer as cheating: Aktipis et al. (2015), Philosophical Transactions of the Royal Society B, “Cancer across the tree of life: cooperation and cheating in multicellularity.” Cells defecting from the multicellular contract is a vivid cell-scale version of the chapter’s thesis.
Commons that don’t collapse: Elinor Ostrom, Governing the Commons (1990): Swiss alpine pastures and Spanish huerta irrigation systems that lasted centuries through local rules. It is group-scale wanting managed without either state or market.
Tinbergen (1963), “On aims and methods of ethology,” Zeitschrift für Tierpsychologie: the four questions give the layered explanation a standard structure.

What would win them over:

One worked, layered explanation of a single behavior across time scales, whether the window dispute or a mother-fetus tug-of-war, with each layer sourced.
At least one real example per scale: cell, organism, person, group.
An explicit proximate/ultimate distinction so “want” is never confused with “was selected for.”
A clear stance on Sapolsky’s determinism, set up here, so the Act I close doesn’t contradict its own source.

Earlier draft

From “Will Creates Difference, Which Creates Problems”

One person works at a desk beside an open window. The air is good; the traffic is part of the background. Someone by the oven is cold and keeps closing it. Both are dealing with the same window, the same weather, the same electricity bill, and perhaps the same request to finish dinner before nine. Yet the situation is not the same from both places.

This is the ordinary shape of difference. A direction is a way a situation matters from somewhere. Once there are several directions, there is variation: one person reaches for the latch while another reaches to stop them. Neither position needs to be a disguise for malice. People bring different bodies, information, habits, obligations, and fears into the same minute. A direction is, in this modest sense, a small disagreement with the rest of the room about what matters now.

Difference makes things noticeable. A sound stands out against quiet. A plan becomes visible when somebody proposes another one. A mistake is a mistake against an expectation. Without variation there is nothing to compare and no reason to revise. Difference can be painful information, but it is still information. It tells us where an arrangement is failing to fit everybody who must live in it.

That does not turn conflict into a blessing. Two wants can be incompatible, and one person may have much more power to impose theirs. “Everyone has their own truth” is not an answer. Positions and experiences differ; a claim about the open window, the temperature, or who has access to the controls can still be checked. Harm does not become harmless because the person causing it has a different perspective.

Repeated choices can make a direction look like a permanent thing. A person who often takes the safe route is called cautious; a workplace that rewards speed is called efficient. Those words may describe a pattern, but they can hide how the pattern was made. Path dependence is a name for one way earlier habits, advantages, and accidents narrow later options. It is a model of feedback, not a sentence of fate. People and institutions can change, though usually not by being shouted at from the other side of the window.

The practical question is not how to remove difference. It is how to describe it well enough to act together. The person at the desk might need fresh air to concentrate; the person at the oven might need warmth; someone else might need a room without fumes. Those accounts can coexist with common facts and shared constraints. They may lead to a different work spot, a jumper, an extractor fan, a time limit, or a decision that still leaves somebody dissatisfied. Precision does not guarantee harmony. It gives disagreement fewer places to hide.

Try the disagreement practice. Begin with the two window positions. Write what each person can see, what each may want, and one fact or constraint both must face: temperature, time, money, safety, access, or another person’s consent. Then write one question that is sincere enough to receive an inconvenient answer.

Difference is not a defect we will eventually outgrow. It is part of what makes attention, learning, and relationship possible. The next question is what wanting becomes when it lasts long enough to include another person, a changing capacity, and a life that has to hang together somehow.
