4th anniversary: Post #2 Genetic watersheds

I look at what we humans do every day all day long in the course of living and see biological marvels. I watch from the perspective of two metaphors, 1: the genetic watersheds of SWP (Solving World Problems) and CR (Conspecific Relations) and their confluences into RS (River Sentience), RE (River Empathy), and their confluence into RC (River Consciousness; and 2: the Soma, its Brain and the MEMBRAIN. These ideas contribute importantly, I think, to understanding how embodied minds form and then come together to create the social mind of culture, a distinctly biological phenomena. Today I will summarize the watersheds. Next post will be about the soma-brain-MEMBRAIN.

watersheds

Genetic watersheds of SWP (solving world problems) and CR (conspecific relations)

The flow from two main genetic watersheds fills our gene pool. Consider that life’s evolution progresses from “a vast reservoir of fortuitous variability”, to use Monod’s phrase, and this variability comes from the uncounted chance mutational events erupting from the ground, most rising and disappearing without consequence, contributing nothing to the watershed’s flow, but some rising to pass muster first as fitting coherently with the other segments of the genome and then as increasing adaptability; these then contribute to the flow down to proceeding generations.

The timeline is quantifiable and unimaginable. Our planet Earth coalesced around 4.54 billion years ago (bya), our moon formed by one or more big asteroid strikes 4.53 bya, our planet’s water was here from the beginning or arrived by more asteroids by 4.4 bya, and evidence indicates that life had begun by 3.7 bya. With that the transition from planetary Earth to vital Gaia began. Incipient life forms began evolving further means of SWP, Solving the World Problem of finding and using nutrients, and speciation developed as life forms spread into new environments and evolved the capabilities needed to exploit the opportunities in new niches. The metamorphosis to Gaia continued until the main phyla extant today appeared by 500 million years ago (mya). The genetic springs in the SWP watershed contributed the increased ability to sense and move and to use different nutrients, all in the service of mitigating exigencies and exploiting chance (these the functions of all life’s existence), and this led to life developing sentience. Thus, the main confluence flowing down from the SWP watershed I have named the River Sentience.

Back upstream a new watershed appeared around 1.2 bya instigated by a powerful spring for sexual reproduction. The flow from this spring enabled a new source of genetic variability, not that of chance mutations but from the recombination of existent genes leading thereby to a more diverse set of individuals from generation to generation. Along with this really monumental development, this spring added on the value of conspecific relations because the search for a proper mate from amongst the great variety of individuals took on an obvious importance. The genetic watershed that developed I call CR for Conspecific Relations. Furthermore, the value of CR increased from the necessity of mate selection to the opportunities of parenting. The springs of the CR watershed began to increase the prominence of cooperation, so that around 500 mya (when the main phyla were settling in) hormonal systems developed that included oxytocin and vasopressin to promote more powerful parenting feelings and behaviors. The genetic flow from CR produced signaling among conspecifics, leading to attachment and bonding with young, the formation of families, and finally, the incipient social relations permitted by new communications among kin and kind. Thus, the main confluence flowing down from the CR watershed I have named the River Empathy.

These two great rivers, RS and RE, flowed down to the ocean of experience, upon the shores of which genotype becomes phenotype, i.e., each species procreates through its individuals, and there we have arrived at the estuarine rebirth of generational life. Here one more important development occurs as a result of the confluence of RS and RE, a confluence made possible by the evolutionary appearance of symbolic thought. The advancement of empathetic communication about the animal’s feeling states of intent, affect and cooperative engagement coupled with mirroring action and intent led to signaling and then symbolic communication about subjectively processed information. As explained elsewhere, with the empathic sense of each other’s mind comes the impulse to share some of the mind’s contents, thereby empowering a new level of social interaction. Now solving world problems (SWP) becomes a shared socially organized activity and conspecific relations (CR) becomes a world problem to be solved. With this development symbolization and empathy interact and initiate human consciousness and culture (the habitus), and so I name the river resulting from the confluence of RS and RE the River Consciousness (RC).

This first metaphor captures the long evolutionary descent of genetic flows that contribute to our species-specific form and renders this remarkable number of infinitesimal chemical and energetic events into two primary flows, SWP that carries out the mitigation of exigency and exploitation of chance in order to gain from the environment what life needs and CR that creates social domains that enlarge Gaia in organizational, informational ways. From this phylogeny we travel on to the ontogeny of each individual soma, its brain (precursor to complex) and the MEMBRAIN in 4th anniversary post # 3.

 

a positivist genesis myth

[This is a very long post. I considered breaking it down into 2 but did not like the results so here it is. Having read the previous post would be helpful and acquaintance with some of the threads running through my blog may help this post be more understandable. Thanks in advance to anyone who reads to the end.]

What do you call a genesis myth without the supernatural? Au naturel, of course. And I use the term myth loosely, meaning an allegorical narrative symbolically capturing an explanation of nature that is, when objectively considered, unexplainable in its totality. Thus we have gods creating each other and the cosmos and humans. We also have the mystic apprehension of the unexplainable universe; one of the first and to my mind still one of the best is the Tao Te Ching (and I really love the translated rendition by sci-fi hero, Ursula K. LeGuin).

I have written here about the ocean of experience surrounding each of us, meaning that domain where the two great genetic watersheds (Solving World Problems (SWP) and Conspecific Relations (CR): see post 4/7/17 ) run to confluence and form an estuarine island of life and mind. A mystic stands on the shore, a being nakedly aware of the generational and temporal flow through to this moment, then this one, and oh, you know, and watches the weather, tides and the waters wave and glisten on the shore, content with just that apprehension, finding that experience a full one, and assured that the knowledge mirroring the experience is meaningful and insignificant. A genesis myth is valuable, even necessary for carrying that apprehension forward into meeting life’s probabilities and necessities.

Though a positivist genesis myth may be paradoxical, when we consider the scientific basis of our genesis presented below, I think that mythic aspect will be apparent because our understanding has come through increasingly sophisticated mathematics and information processing. Most of us cannot really comprehend how the numbers show their truths as the mathematically keen scientists do see them. In this sense scientists are like the seers, shaman and priests who created and developed the supernatural myths: only the initiated have access to the genesis esoterica as gleaned from either the mathematical domain or that learned through communication with the supernatural divine. Scientists talk with numbers and priests with angels. (I pass over the crucial differences in replication, falsifiability, and transferability between the two). We may not usually think of science in this way but in truth the majority of the people on Gaia evaluate positivistic myths and find them much less comprehensible than their religious mythology.   Conversely those of us initiated into this scientific world view, both the lay and the practitioners, can still find some truth about humanity in the old myths but little fact, certainly not enough to guide our pursuit of knowledge. Religious myths are at this point best seen from without, i.e., as data as we seek to understand our humanity.

In my last post I talked about Monod’s ethic of knowledge, and so to journey even further above my pay grade, this constitutes an epistemological effort that needs some supporting concepts about reality; about what is it we are learning? How did it come to pass and what is my relation with it? My bias is that any statement about the ultimate nature of reality, i.e., metaphysics, ultimately and necessarily given the scale and scope of our capabilities relies upon, revolves around and devolves intellectually into mystic apprehension. The question here is how from a cold, mechanical and valueless though lawful universe can life evolve with its values, as it has clearly done here with us on Gaia? That is, how to account for both our knowledge (true knowledge formed from an ethics of knowledge based upon empiricism) about the world and our values as both are clearly, as Monod demonstrated, sociobiological in origin. So again, what is it we know and value?

Human culture, though composed from both knowledge gained and values held, is a virtual world imagined among group members that helps to govern or to channel how each individual goes about life and supports the group. Over the past few thousand years, cultural parsing has held knowledge as more secular and values as coming from a supernatural divine. The ancient Greeks attributed some values, e.g., hospitality to strangers, respect for the dead, obedience to the king, acceptance of fate, to their gods, while they initiated a grand tradition of intellectual effort, i.e., philosophical and scientific knowing. The ancient Israelites certainly attributed their values to Yahweh and I believe follow a more secular and pragmatic approach to knowing. The Taoists stand on the shore and seek the Way. We don’t know about the people who painted the caves 40,000 years ago, much less about the earliest Hominids who buried their dead, but we do know that from them and since the advent of agriculture, civilized knowledge and values have grown to compose today’s cultural worlds.

Accept for a moment that all culture is learned and that we acquire culture through mirroring, empathy and symbolization. Assume even further that we can understand how we benefit from experience in such a way that cultural invariants form inter- and intra-personally that then guide how we relate, communicate symbolically, conceptualize with words, use metaphor, govern individual actions and relationships, organize socially, etc. Understand that early groups form on the basis of kinship which yields a natural historical narrative through their ancestry, while other groups form through social roles irrespective of kinship, and so must bond through constructing and sharing relevant narratives, some literal or empirically based, e.g., a flood, and some mythically based, e.g., the afterlife. All this to say that our philosophy as currently conceived results from a long history of cultural development (or is that evolution? Erwin Schrodinger, for one, wondered if humans were done evolving, i.e., we would stay in roughly the same biological form now into the future, sort of like sharks and insects have been the same for roughly 200 million years, so any further evolution for us would have to be cultural).

John Locke said the human infant was a tabula rasa, i.e., a blank slate, upon which experience writes its tale. Today we understand much more about what the child brings to the table and that there is no ontogenetic blank slate. But this idea covers only a very short time scale of one life. Monod from his scientific perspective seems to endorse John Locke’s tabula rasa, i.e., blank slate, but says the blank slate has been written on by the entire history of life, i.e., “the experiences accumulated by the entire ancestry of the species.” So our capabilities flow from incipient life some 3.5 billion years ago. Yeah, it was a blank slate then, but much has been written on it since and much has been edited, erased and replaced.

As I discussed in the previous post on Monod’s book, our evolutionary experience has led to two cultural facets from which mythic values seem to arise. One is an inborn fear of solitude; we are social animals and do not do well in isolation. Our contemplation of the cosmos along with our knowledge gleaned so arduously through empirical efforts indicates that our place in the universe is indeed lonely; we are warm-blooded strangers in a cold place, each conscious of our irrevocable solitude within our own MEMBRAIN, and constantly filling our mental void with all kinds of energies. The other facet derives from the first; we have, Monod says, a “need for a complete binding explanation” of our existence, and that includes the gaps before birth and after death. How have we come here now to stand on the beach of the ocean of experience? Both of these facets are inherent in life as it has developed on earth; they are inherent in Gaia’s character, i.e., they follow from life holding forth through negentropy amidst a universe flattening out in entropy. Each soma operates to replicate the passage of genes while mitigating exigencies and exploiting chance opportunities until its lapse into the final entropy of death.   This view of life is consistent with Susanne Langer’s idea that human consciousness arrived with the understanding that our life is one act that begins and ends and that within that frame each of us lives alone. Also consider Camus’s Absurd and the myth of Sisyphus and most especially Chris Hitchens’ proposal to separate the noumenal from the supernatural (see post 4/13/17).

It is as I have pondered Monod’s Chance and Necessity and sought its relations to other readings, e.g., Langer, Dawkins, James, Whitman, Hawking, etc., that I have developed a frail metaphysical myth to support this ethical epistemology, keeping consistent with my basic approach to the biological roots of our humanity and moving forward through a dialectic between positivism and mysticism (see posts beginning 11/15/15). To be clear, I believe any truth of which we are capable of apprehending is a gem with many facets, some more transparent and therefore practical or at least knowable than others; the goal is to see the gem whole even given our limited access to various facets. The metaphysical and epistemological answers to the questions of solitude and significance that used to be answered by animist myth with reference to the supernatural (and these serve us well for some purposes still, like artistic imagery or, as indicated, anthropology) are now superceded by positivist myths with reference to the natural world (and these can serve us better if we develop and use an ethics of knowledge to organize our culture and civilization). So to give an abstract rendition of a positivistic genesis myth:

  • Consider the big bang, or any theorized notion of this cosmic course through time, e.g., expansion and contraction, parallel universes, multiple dimensions beyond 4, etc.
  • These refer to the void beyond our comprehension and how the universe developed in ways we can comprehend.
  • A void filled by energy that illumines no forms =>
  • Higgs field appears whereby energetic matter gains mass (see delightful illustration at: http://www.nytimes.com/interactive/2013/10/08/science/the-higgs-boson.html.)
  • Matter and mass, though we apprehend them through our senses on some macro level, actually operate on a micro level through quantum waves of probability =>
  • These waves swell, subside, interfere +/-, and break into present reality: this is the first level of chance and necessity, i.e., quantum probability reduces to a certainty, e.g., Schrodinger’s cat is either dead or alive but not both because that wave has crested and broken on the shore
  • Matter with mass coalesces and clumps even as the incipient energies undergo entropic dispersal
  • The clumps accrue in the spacetime continuum =>
  • Gravity is a manifestation we can discern of this negentropic building process, i.e., against or resisting entropy; the spacetime curves according to this history of amalgamation
  • Gravity assembles cosmic structures that become elemental forges, e.g., stars burn and synthesize heavier elements: this is a next level of chance and necessity in that cosmic structures, e.g., gas clouds, galaxies, stars, planets appear by chance and then follow a time line ruled by necessity
  • The next level still of chance and necessity is when some combination of the products of these elemental forges coalesce through a gravitational eddy to generate life, e.g., planet Earth becomes Gaia.
  • Once begun life evolves according to chance and necessity.

This would be our genesis story if it were constructed as an anthropomorphic narrative; it is more detailed than animist origin myths because it is empirical and dynamic; the big difference is, of course, that this genesis details a cold, mechanical, and valueless universe from which life evolves with its own sociobiological values. Religious people may find that a problem but those who pursue an ethics of knowledge do not, because we realize that any and all value appears through and from life. Consider these incipient values I find apparent in Gaia’s biosphere:

  • Of course the first value, though perhaps one of the last to be understood, is to understand the world through realistic means and action.
  • Life’s projection into the future through replication, e.g., procreation is good for many reasons
  • Generational replication via somas is quite conservative by necessity and its sensitivity to chance events allows evolution to proceed in two ways:
  • One, variant genes must fit coherently into the whole genome or they will not continue
  • Two, having done so these variants become invariant and must pass muster through environmental interaction by demonstrating the same or increased adaptability
  • Each and every soma operates to minimize exigencies and to exploit chance
  • Their capability to do so speaks to their evolutionary potential.
  • Somas with brains do better than those without, somas with strong social relationships, i.e., have MEMBRAINS, do the best.
  • All life is interconnected
  • All life is local and Gaia is the location; each soma participates in the ecological balance
  • We must respect Gaia, understanding that the whole is greater than the sum of its parts and that our actions even if performed authentically with sound knowledge and conscious values have many intended and unintended consequences.
  • Our ignorance is greater than our knowledge, e.g., standard theory of physics about 10% of the universe and the rest dark
  • Finally, while we accrue our knowledge through scientific means, both empirical and theoretical, our values continually emerge from the ancestral history of our species. I hope to expound upon this more in later drafts.

With this first axiom of procreation (replication) and its two corollaries of mitigating exigencies and exploiting chance, our frail metaphysic grows strong enough to support a new domain of values instigated and developed through evolution with conspecific relationships. With our heightened empathy and symbolization, we become conscious of greater questions, that of our solitude and of our significance, that can find only partial answers through our ethics of knowledge and development of values.

We have no way of comprehending this richness of life on Gaia. We may work on constructing our ethics of knowledge based on a positivistic genesis myth for our metaphysics, which can lead to a knowledge of ethics and a better understanding of our values. That effort, for me, resolves to a dialectic between my biological mysticism and my intellectual pursuit of knowledge. If you have read all of this, I again thank you. Linger here if you like watching the ocean waters wave and glisten upon your shore or travel on the Way.
