Thanks Stephen,

I hoped for some sort of answer like that.

If Eisenhower was the president for the Age of Collective Reasonableness, and Reagan wa the president for the Age of Noble Selfishness, and Trump is the president for the Age of Anarchy, what is next?  How does a complexity theorist plan his way out of this one, baby?  Inquiring geezers want to know. What do the ants have to say? I want to say that we ants should all get together and think this through, but that is, of course, exactly what a geezer from the ACR would say.   I do despair.

Nick — you came to Santa Fe to “confront The Enemy – Complexity,” but I’ve always admired how that move was also a reach to extend the individual into the group. Your framing of evolution beyond the lone actor fits naturally into complexity’s home territory: the study of collective dynamics.

Complexity challenged the civic ideal you grew up with — that we could make our best guess about the future, then plan together calmly and rationally around stable facts — by showing:

  * The world is nonlinear — small perturbations can cascade.
  * Prediction decays fast — best guesses expire before guiding
    long-horizon plans.
  * Feedback loops are short — conditions shift before consensus can
    form.

From the Victorian lens of the forward-propagating individual — the gene, the photon, the solitary actor — the unit of selection is the forward-propagator itself, competing with only a once-in-a-lifetime reproduction as feedback, with everything else treated as downstream consequence.

But complexity might instead be the handshake of duals — like the mutual adjustment of fireflies flashing in unison or pendulums entraining to a common rhythm — where coherence emerges from continuous exchange, not solitary advance. This shift is much like physics’ move from solid state (crystal order, replication) to condensed matter (emergent phenomena, reproduction) — the very distinction Eric Smith draws between systems that merely repeat and systems that generate novel, coherent forms.

This spirit runs through the science:

  * Stuart Kauffman’s autocatalytic sets — molecules persist as part
    of collectively closed webs of reactions.
  * Harold Morowitz & Eric Smith — life’s core metabolic cycles may
    emerge as planetary-scale solutions to channel geochemical energy
    flows; selection might happen at the network level, not
    molecule-by-molecule.
  * Afred's Hübler’s ball bearings  — conductive spheres collectively
    grow to dissipate massive charge gradients more effectively.
  * Per Bak’s self-organized criticality — critical states are
    properties of the network, not any single grain or fault.
  * Ilya Prigogine’s dissipative structures — ordered patterns like
    Bénard cells exist only through system-wide throughput of
    energy/matter.

Physics offers a parallel in Feynman–Wheeler absorber theory, where interactions are bidirectional handshakes between advanced and retarded waves, settling into a self-consistent exchange. Carver Mead’s Collective Electrodynamics carries this into the macroscopic: electrons act as part of a global configuration, not as isolated particles.

It’s the same dynamic in my favorite ant foraging model: food-seekers diffuse “nest” pheromone outward, nest-seekers carrying food diffuse “food” pheromone outward; each biases its walk along the other’s field. The shortest-time path emerges from the handshake between complementary propagations, not from any one ant “deciding” the route.

Seen this way, complexity might not be the death of rational planning — it could be pointing us toward a different design target: the coherent configuration. We're still on the lookout for our “Carnot” to formalize these principles.

And for me, that search has been shaped by the voices in this group — especially yours. Your probes have been part of the collective dynamic here, and I’ve been heavily informed by them. For that, I’m grateful.

    Ok, but I am not done with my infernal questions.  The way you
    pose your question, I cant help thinking that you know  the
    answer.  You and I could recite fo one another the thousand ways
    in which we know that humans are groupish.  We know that people
    can make sacrifices for the good of groups of all sorts, some of
    which are incorrigibly abstract. We know that humans identify
    with the fate of other humans to the extent that they will put
    aside their own good fortune for that of an iconic figure.  We
    know the people are capable of appalling group nastiness.  There
    is no savagery like the modern army, sitting around in an
    anonymous office bloc in New Jersey lobbing missiles at wedding
    parties in Iraq.

    So what is the question concerning human groupishness .   What is
    it beyond these facts that you need to know and what will change
    when you come to know it.  One question you might be asking
    yourself is “Am I justified in keeping any money I earn beyond
    the median income of my fellow citizens. The answer is almost
    certainly, “No”.  Knowing that  and knowing that I am damned
    well  not going to give it away, what next?”

    One of the hardest projects to take on is the discovery of one’s
    own hankerings.  Glen, Jon, and DaveW have been very good at
    exposing mine.  Make American Rational Again.  Return to the
    genteel rationalism of the Deweyan 1950’s where every town had a
    town meeting and every discussion was “informed” by the “facts.” 
    (And we were all cheerful racists instead of the guilty racists
    that we are now.) That I have grown up and helped to create a
    world in which nobody knows anymore what a fact has been like
    living my worst childhood nightmare.  I was head of our planning
    board for three years in the early 70’s where I learned that
    small towns are the scariest, least rational places on the face
    of the earth.  When we moved in from California, marginal
    hippies, the town could not rest before it was decided whether we
    were Catholics or Protestants.   What???!@!!  Sorry, I am
    ranting.   I moved to Santa Fe 20 years ago to confront The Enemy
    – Complexity, which made nonsense of the idea making a best guess
    for the future and planning for it collectively , calmly, and
    rationally.  The idea that people should build businesses models
    on destabilizing the present and then swooping in and pillaging
    until one has established an irrevocable monopoly on the future
    just seems WRONG to me. I loved the idea of American
    exceptionalism. But lo and behold, we were exceptional in only
    one respect.  WE had discovered destabilization as a business
    model. Drop by, plant a lethal virus, wait a few years and then
    return (with your slaves) to a “virgin” land populated only by a
    few desperate savages.  Let the rape of the virgin begin.   Calm
    down, Nick.

    These are my commitments, and I cannot escape them.  What are yours?

    Nick,

    Too good to miss — I’m in. Lead me into the jungle of group
    selection, especially the human variety.

    What I’m after: a clear, simple (but not dumbed-down) take on
    what group selection in humans is, and why it might explain our
    behaviour better than individual selection alone.

    Happy to start at the very beginning — dawn of the argument, cave

    And yes, send me that Famous Great Amateur reading list. I
    promise to read it with respect… and just enough suspicion to

        Hi, Pieter,

        Let me be a George to you as you explore this topic.  I will
        try to respond off hand, quickly, and unself-consciously as
        you think along.  I think this whole topic is fascinating
        both substantively, and historically.   The literature seems
        to track (or lead?) the Zeitgeist so precisely from post war
        peace-nikery (Wynne-Edwards), to the revanchist academic
        Reaganism (Williams-Dawkins), to chaos (evodevo). It's really
        hard to take the whole argument seriously once one begins to
        understand how complex and multi layered are the mechanisms
        by which parents do and dont resemble their children.   One
        of the tools to thinking straight is to own up to one's
        hankerings before one dives into the literature.  What are
        you hoping to find?  Post war peace-nikery was covertly
        deistic,  hoping to find that there was some sort of over
        arching regulatory agency that would keep the species and the
        planet safe. Academic Reaganism said good luck with that! 
         Success is virtue.  And then evodevo, the bull in the china
        shop of that whole argument.  I recommend reading the
        biologist, Sean B. Carroll, (not the physicist), Endless
        forms most beautiful, and The making of the fittest.   It's
        really hard to take the whole argument seriously once one
        begins to understand how complex and multi layered are the
        mechanisms by which parents do and dont resemble their
        children. That there is any resemblance at all begins to seem
        like some sort of miracle.  Or perhaps just momentum.  One
        hankering that misleads us is naturalism, the idea that we
        can find some sort of MORAL guidance in the way things are. 
        Is the opposite hankering, existentialism?  The belief that
        what makes humans special is their power to CHOOSE.  You
        should remember that I am not a philosopher and am, in fact,
        an amateur in all things.

                Thanks Pieter,

                Sorry I have taken so long to get back to you.  If
                FRIAM ever started a journal, it should be called
                “the emperors new clothes”.  We are not committed to
                anything if not to the validity of an “amateur’s”
                perspective.  As people will be quick to tell you,
                mine has always been of that sort.

                If I read you carefully, the position you take is
                that laid out in Dawkins The Extended Phenotype –
                that the genes are the basic unit of selection.  But
                as Dave Wilson has been pointing out for years, Who
                made that decision?   For one thing, as epigenic
                studies have made clear, when one looks in detail, it
                is really hard to find a thing that is exactly the
                gene.  For another, that decision runs the risk of
                confusing the the thing that is selected with the
                forces that are selecting it.  Whatever level you
                care to calculate the impact of selection, it is
                differential group success that is driving selection
                or it is not group selection.  And if it  is
                differential group success that is driving selection,
                then it is group selection. I think you might quite
                enjoy The Extended Phenotype.   For a whild ride,
                have a look at Elliott Sober and D. S. Wilson’s
                Reintroducing Group Selection to the human behavioral
                sciences.  There is a wonderful metaphor in there
                about two riders riding three horses.  It was the
                article that broke the tide for me.  I had been
                totally up Dawkins ass for the preceding 20 years.

                Nick, I'm genuinely impressed. Honestly, I feel a bit
                out of my depth trying to respond meaningfully on
                this topic.

                So please take my reply in the same spirit I’d expect
                a response from my 10-year-old grandchild when
                debating computer programming with me. The gap
                between your understanding of evolution and mine
                feels about that wide.

                That said, I’d still like to offer a response to your
                group selection argument—fully aware that it may come
                across as amateurish, and I'm okay with that.

                Here's the question I’m grappling with:

                Is the following valid?
                Genes as the Unit of Selection:
                Modern evolutionary theory generally views genes as
                the primary unit of selection. Natural selection acts
                on individuals, and the success of an individual is
                ultimately determined by the genes they carry.
                Group Selection as a Modifier:
                Group selection can be seen as a process that
                influences the expression of genes. For example, if a
                group-level trait (like cooperative behavior) is
                advantageous, then genes that promote that behavior
                will be favored, even if those genes also have
                individual-level costs.

                    Nick,

                    I wish to embody the fear of being dragged away
                    from what you think you are supposed to be doing,
                    to be engaged in the topic you raise in your paper.

                    I have read the paper before and, as then, I find
                    it meritorious, well written, and reasonable in
                    argument. I am, basically, convinced.

                    However; two points:

                    First, your use of the concept, "metaphor," is
                    the way that I use the term, in a manner that
                    glen pointed out is inconsistent with the literal
                    definition of the term. I speak of metaphor when
                    there is some thing of which I think I know
                    something and I have a suspicion that some other
                    thing might be of the same ilk. I use what I
                    think I know to craft a 'model', one that
                    suggests particular points and particular
                    relations that, if my suspicion is correct, will
                    have direct analogs in the unknown thing. I check
                    them out individually and in combinations and, if
                    substantiated, confirm my suspicion. If
                    unconfirmed, the metaphor is refuted.

                    This seems to me to be what you are doing in the
                    paper, albeit it more abstractly and
                    academically. Please correct me if wrong.

                    Second, and here is the real time sink, would it
                    be possible to make your ideas concrete, real
                    groups with actual history and demonstrated
                    differential "success." If you were amenable to
                    such a conversation, I would propose the Mormons
                    as a test case.

                    One of 20 or so "religions"/"societies" to emerge
                    from the "Burnt Over District" of western New
                    York. The only one still extant.

                    Disproportionately successful, (in material and
                    social terms), to their neighbors. Smith was
                    living in a two-story New England style home
                    while down the road, Abe Lincoln, was living in a
                    log cabin with mud floor.

                    A schism immediately after Smith's death, with
                    the Reformed LDS barely evident while the main
                    group flourished. (Last time I checked, Mormonism
                    and Sokka Gokai, in Japan, were the two fastest
                    growing religions.)

                    In Utah there was a concerted effort to spawn
                    multiple small groups by sending out colonies.
                    Because each group was originally "seeded" with
                    four or five families, you get a strong
                    genetic/heritance component as well as "traits."
                    (It is still possible to identify what part of
                    Utah someone is from (especially females) by
                    their physical appearance.)

                    Some interesting "adaptations" at the trait
                    level, e.g., when Smith was alive blacks were
                    included in the community and held the
                    priesthood—something that Missourians, at the
                    time, could not abide. Brigham Young 'suspended'
                    (restored in 1978 with the admission that the
                    suspension was not for theological, but merely

                        interests together in  a paper called
                        “Shifting the Natural Selection Metaphor to
                        the Group Level. There are two things about
                        this paper that make it salient for me. The
                        first is that I think it is the best paper I
                        ever wrote.  The second is that for each of
                        the two people whom I most hoped to reach
                        when I wrote it, D. S. Wilson and Elliott 
                        Sober, it is a piece of  crap. In it, I try
                        to show that the problem with metaphors is
                        not with their use in scientific thinking: on
                        the contrary, it is with their
                        ill-disciplined use.  Metaphors need to be
                        worked in a systematic way, not simply flung
                        out in a gust of poetic exuberance.  This
                        lesson  I try to teach by working the natural
                        selection metaphor in a systematic way to
                        show that if it had been treated seriously in
                        the first place, the whole dispute about
                        group selection might have been avoided. 
                        Thus the paper is not only arrogant, but
                        meta-arrogant.

                        Nothing is more pitiable than the retired
                        academic who would do anything to have
                        anybody read his moribund essays.  But, alas,
                        I simply am such a person. So, I am attaching
                        a copy of the paper  in the hope that it will
                        have some value to you within the context of
                        your two discussions.

                        Mumble,

                        Nick
