Let’s talk doxa, science, and humanity

Recall from my 6/7/17 post on Pierre Boudrieu’s writings that the doxa comprises the entire realm of possible discourse; anything outside the doxa is difficult to discuss—it is ineffable or inchoate. Within the doxa the dominant paradigm or pattern of beliefs and knowledge is orthodoxy, which mostly controls the domain of discourse, while deviant thinking would be heterodoxy. In religion heterodoxy may become heresy, e.g., the Pelagian heresy that one can attain salvation through good works. In science heterodoxy can fall by the wayside if it fails to account coherently and productively for the subject phenomena, or it can replace orthodoxy because it eventually is found to provide a more robust explanation. The classic example is Thomas Kuhn’s scientific revolution in the shift from the Ptolemaic earth-centric universe to the Copernican heliocentric one.

A more modern example comes from Naomi Oreskes and Erik Conway’s book, Merchants of Doubt, about a small group of scientists who act to obscure the valid findings about hot issues, such as tobacco’s carcinogenic effects or the human contribution to global warming. The question they raise is how to tell a fraud from a crank, who may or may not be on to something wrong in the orthodox realm of discourse (see post 3/7/16). Oreskes has discussed the eventual acceptance of plate tectonic theory, 50 or more years after Alfred Wegener proposed it in his 1912 book. Evidently the theory was accepted in Europe long before it was accepted in the USA, where Wegener was seen as a bit of a crank; here in the USA they could not imagine a meteorologist like Wegener developing a valid theory about earth’s geology, so Wegener was seen then as a crank whom we now understand had a good idea. And the climate change deniers are still the same old frauds from the tobacco scam.

Now the study and understanding of our humanity has likewise undergone some great shifts; some of the most profound transformations from heterodoxy into orthodoxy came with the Enlightenment and science’s assertion that humans were a proper subject of study outside of religion, Darwin’s assertion that man was just an earth-bound animal, Freud’s assertion that conscious life is a construction of non-conscious processes, etc. More recently Norbert Weiner’s initiation of cybernetics revealed the structural similarity of control systems between biological man and machine, a gap that grows increasingly smaller as science progresses. I would also include Jacques Monod’s assertion that our biology in its foundation of molecular genetics can account for life without any recourse to supernatural creators, thank you very much, so that his understanding of spirit looks to the generations of life over the past 4 billion years on Gaia. That would be his mystic beyond, not Olympus or heaven or whatever (see post 3/25/17).

I would like to think that one particular heterodoxical idea is also usurping some of the orthodoxy in cognitive psychology, but alas, I do not see a tectonic shift happening here. I do remember when cognitive psychology was heterodox, back in the days of behaviorism’s puritanical orthodoxy, and then psychologists had the good sense to admit that we had minds, that we actually thought and that our thoughts had purpose and effect. Now cognitive psychology seems to exert its orthodoxy through control of the doxa, especially through its alliance with information science and focus on algorithms. Everything mental is thinking more or less logically, you know, in the cortex, while affect and emotion are lower. Thus the predominant and errant metaphor of ‘hard-wired’ as we neglect intuition, feelings and emotion.

But consider some seemingly disparate ideas. I first caught a glimpse of an alternative seeping into the doxa when I read Susanne Langer all these years ago. The title of her last work gives us a hint, Mind: An Essay on Human Feeling, in its last word, ‘feeling.’ She arrived at her examination of mind as biological through her study of art, understanding that art is a different kind of symbol, i.e., presentational, than language, i.e., discursive. Its structure is different because its elements of composition are different, and while both types of symbols have surface and deep structures, the latter for art is better termed aesthetic import in contrast to linguistic meaning (see post 11/10/17). Peruse some books addressing the evolution of our minds and see how often art is considered as an important phenomena in its own right of our humanity. Daniel Dennett’s recent one briefly addresses Bach and his music not so much as art but as an example of cognitive design. Patricia Churchland’s 1989 Neurophilosophy mentions music twice, art and symbols not at all. Trying to expand my own doxa is one big reason I read books like Kandel’s on art (see post 7/23/17) and plan on reading one by Ramachandran soon. This is why I think the development of an instrument to reliably study our emotional response to art, Aesthemos (see post 10/31/17), is an important step forward.

Consider also how maybe 50% of an important neurotransmitter, dopamine, is synthesized in the gut, how even more serotonin is found there, and how our gut microbiome affects mood and thinking. Consider the work by Tversky, Kahneman and others showing that our minds are not clean cognitive operations but filled with heuristics that generally satisfice in most circumstances but lead us astray in some important others and emotions play no small role in that. Consider Gavin de Becker’s Gift of Fear underlining the importance of paying attention of our feelings of danger. Consider how disrupted attachment, you know that basic emotional bond, affects thinking in the social realm, hindering social perspective and empathy, and in cognitive realm, hindering understanding of cause and effect, sequencing, etc. Consider how the Texas tower shooter, Charles Whitman, sought medical help repeatedly when he felt something was wrong with his mind because murderous thoughts were so prominent and intrusive, how doctors dismissed his concerns any number of ways, e.g., just depressive feelings, and how autopsy revealed a fast growing tumor on his amygdala, an emotional control center affecting thinking and behavior. All of this suggests that feeling is coequal with thinking, or at least, that both are important functions in the nervous system responsible for our mind. This idea is what Langer promoted at the end of her career.

I have just finished Michael Tomasello’s book, The Natural History of Human Cognition, following up on my reading of his book on human morality (see post 7/31/17). Both books compare simians and humans to see wherein we are different, i.e., what makes us human. This one hypothesizes how we developed more or less objective thinking over the past 100,000 years of our evolution. It is interesting and thought provoking, albeit written in an academic and somewhat tedious style. He focuses pretty exclusively on human cooperation, which is assuredly distinctive in the animal realm, and how our thinking developed “collective intentionality and agent-neutral thinking”, going from an individual perspective taking to group perspective taking to thinking objectively, i.e., valid from any perspective. (Yes, I have foreshortened his arguments terribly but I want to get on to another point).

Tomasello does not really address very directly the issue of human feeling, but he comes close several times. And to be sure at the end he makes a strong statement that our cognition is socially based and that our culture, including art, is based upon the development of human cognition with some semblance to his outlined hypothesis. Before that we read statements hinting at the importance of relationships (and feelings?).

  • As distinct from other great apes, early humans began mating via pair bonding, with the result that nuclear families became newly cooperating social units.
  • [Other great apes do not have] human-like joint goals; there is no cooperative communication for coordinating actions.
  • Great ape cognition and thinking are adapted to this social, but not very cooperative, way of life.

Tomasello argues that this cooperative way of life, developed in response to ecological variations, led to “Thinking for cooperating”.

To be clear, I think Tomasello’s arguments are quite robust as far as they go albeit with one caveat, and that is reflected in his statement, “Humans have thus constructed learning environments within which their own offspring develop”. That we have learning environments is true, to be sure, but that we ‘constructed’ them elevates our ability of rational control above rational limits. Even our modern child rearing arrangements are based upon cultural evolution by historical accident, and while we think we know what we are doing, we also know that unforeseen consequences are unavoidable and that much of our success in promoting child development comes from attending to the basics of emotional attachment, group relationships and play. Yes, cognitive skills are important there, both to develop and for developing, but the contextual process is not one of ‘construction’; our rationality is quite limited in its intentional power because so much is unconscious. (Consider Daniel Kahneman’s quote in Thinking Fast and Slow from Herbert Simon, “Intuition is nothing more and nothing less than recognition” of what rises for conscious presentation from subliminal processes and feelings play a larger role in those processes than some might expect or include in their discourse).

With that caveat expressed, I want to expand on what I think the context is, i.e., what lies beyond where Tomasello’s argument falters, or more to the point, what our current orthodoxy seems to neglect in its discourse. Once upon a time, a long time ago, in the early 20th century, before information theory and molecular biology transformed biological, including psychological, science, some intellectuals focused on symbols. As I hinted above, topics like feeling, art, and symbols are not well represented in more recent books, and there we have lost something. I came of age appreciating C. S. Pierce’s and Ferdinand de Saussure’s theory of semiotics, Ernst Cassirer’s philosophy of symbolic forms and his notion of man as a symbolic animal, the Sapir-Whorf hypothesis, Noam Chomsky’s theory of mind and linguistic structure, and of course, Susanne Langer’s keen and profound insights on presentational and discursive symbols.

When Tomasello writes that children and apes have “very similar cognitive skills for dealing with the physical world” but that even very young children already have “more sophisticated cognitive skills [than apes] for dealing with the social world,” the question arises why? How is it that humans have developed a more cooperative umvelt along with symbolization? I would argue that our empathic abilities motivated concerned, prosocial action, but the key issue for me here is how the powerful relationships between surface signals and deep structures, e.g., semantic meaning for discursive symbols and artistic import for presentational symbols, developed. My intuition over the years has repeatedly presented for my recognition the idea that human intimacy and symbolic forms are indeed related and that between the two, intimacy is primary. Here’s the deal:

To progress from signs and signals with their isomorphic referents to symbolic surface and deep structures requires a more powerful sense of what exists in another’s mind. Consider these distinctions:

  • between a raven’s caw when chasing a hawk and a person shouting fire
  • between the raven’s roosting at evening and a person watching the colors fading at dusk
  • between skipping a rock across a lake and cracking a nut with a rock
  • between a green light at an intersection and the green light on the dock at Daisy’s house Gatsby sees across the bay.

In each case the first example involves a signal with acutely circumscribed significance and the second involves a metaphorical vehicle with a tenor of deeper significance. (Consider that Lakoff and Johnson develop a useful epistemology through symbols and metaphors in their book, Metaphors We Live By.)

Consider now the ontogeny of human relations in the important basic development of attachment and emotional regulation that leads to adaptive prosocial relationships. This is primarily a function of the right side of the brain, as the research summarized by Alan Shore shows, and it is here that a sense of self initiates hopefully to become one of empathic cooperativeness. With further development a neural center serving the higher or extended functions empathy in the right hemisphere around the OTP (occipital-temporal-parietal) junction (what I call Empathy Central or EC and the orthodox call Theory of Mind or ToM—see post 10/31/16). This is analogous to the left sided OTP area known as Wernicke’s area that serves semantic meaning, so the right-sided OTP would analogously serve empathic or social-emotional significance. That would serve as the basis for aesthetic import that arises, I think, in a much more complicated manner through a more widely organized system. Humans have a highly developed sense of self and empathy with another self, and while this enables cognitive perspective taking, it remains a function based on feeling, just like the left sided grammatical functions are based upon grammatical feelings of fitness, e.g., this feels right and that doesn’t as in Chomsky’s “colorless green ideas sleep furiously” is grammatical but meaningless and Yoda’s “A jedi will you be never” is not grammatical but meaningful. (Compare also phenomena of handedness; cross your arms right over left and left over right and one will feel more comfortable or fit. Same with clasping fingers with right or left thumb on top or throwing a ball with right or left hand.)

The idea here is that human attachment paves the way for intimacy and a keen sense of another’s mind, that this is primarily a right sided function that matures before the left sided language and that the two sides communicate with each other in the coordination of communicative behaviors. Consider next the arcuate fasciculis, a long fiber tract that on the left side connects Wernicke’s and Broca’s area and is a part of the mirroring system. The arcuate fasciculus facilitates verbatim repetition of what was just heard, i.e., it helps connect the auditory signal constituting the surface structure to the motoric plans for saying that same surface structure (see post 4/24/14). No meaning is required, but here is the catch. Remember a time when you heard someone say something but did not quite catch the total message. You probably rehearsed silently using the arcuate fasciculus what you heard until you were able to decode and complete the surface structure and so glean its meaning using both your analysis of the communication signal and your composition of context, including knowledge of the other person and the situation.

This example demonstrates, I think, a basic insight into the development of human symbols. A signal, i.e., surface structure, carries its deep structure through our empathic apprehension of another’s mind and its presumed contents; we ‘know’ more is there and can even surmise what it might be through EC. Without that evolutionary step symbols could not develop. (Hey, what a perspicacious title for my blog, eh?) That deep structure may be conventionalized and carried by lexical items as in discursive language or not conventionalized, its formal or aesthetic import carried by the presentational art symbol. Without the active inclusion of both symbolization and empathy in our doxa, orthodox discourse will have difficulty bridging the gap between, as Tomasello quotes Donald Davidson, human evolution “from ‘no thought’ to thought’.” The heterodoxical statement, “No thought without feeling” may be heretical but should still be part of our discourse as we strive to bridge that gap.

And now travel on with feeling. Happy New Year.

hie you to the NCMA

Yes, hasten to the North Carolina Museum of Art to see two temporary exhibits on M. C. Escher and Leonardo Da Vinci.  The first is one of the most complete exhibitions of Escher’s art and he had a long career.  I knew the Escher impossible space ones, but those seemed mundane next to his earlier ones exploring long and deep perspectives.  He produced phenomenal art from late teens to his death in 1972 at age 73.  Escher was especially inspired by Da Vinci because of their shared passion for geometries and mathematical patternings.

Escher

M. C. Escher

Da Vinci’s work is represented by a wonderful exhibition of the Codex Leister (now owned by Bill Gates and thank you, Bill), his journals, written in mirror writing, that concerned his scientific and engineering efforts to understand and control water, how fossils come to be at the mountaintops, how water which always runs downhill can emerge in mountain springs, how to measure water pressure, and well, I hope you get the idea.  Many pages written in a fine delicate hand with very precise drawings mostly on the margins.

LEONARDO

Leonardo da Vinci

In a couple of passages in the Codex Leister da Vinci presents a view that the earth is like a body, the ocean its heart, its rivers the blood vessels, the mountains its bones, the vegetation its flesh.  So he knew about Gaia early on in the development of positivistic science; indeed he was one of the creators of science and engineering, both imaginal and practical, even as he was an artist of enormous range and power.  Talk about a hero, who first walked the dialectical path between mysticism and positivism showing us the way.

On a wall in the Escher exhibit was a quote from da Vinci in which he discussed how looking at a rock face one can see shapes and objects emerge or listening to chimes one can hear words and melodies.  This is from his Art of Painting.  And it also fits with the paleolithic cave art in Europe, where the beautiful paintings of animals take advantage of the natural contours of the walls (and who knows, the shadows from the torch or candle).

So hie yourself to the NCMA if you can; it is well worth it.  And look for this guy wandering the dialectic.
