I’m going to run through my sources in no particular order. I don’t intend to show a comprehensive view of human cognition, or even necessarily a consistent one. As I noted, I just want to get a feel for how mental processes in general might look and work and good ways to talk about them.
“The Language Instinct” by Stephen Pinker.
Stephen Pinker is a professor of cognitive science and psycholinguistics at MIT. This book provides a very detailed presentation of his understanding of how human language works and how it develops in children, making specific reference to scientific evidence including studies of the effects of brain damage caused by trauma, disease, or birth defects; the results of PET, MRI, and other imaging on living brains; language learning in healthy children starting at infancy; language performance by adults and children; genetic studies of families with a history of language disorders; studies of twins separated at birth; comparative studies of world languages; and others. According to Pinker, the findings presented in the book apply to all human languages studied.
Pinker’s conclusions I think are relevant to this discussion include the following:
Language is instinctive. He quotes Darwin as saying that language is “an instinctive tendency to acquire an art.”
Language does not control thought, it’s the other way around. The book includes a section debunking the Whorf hypothesis, which claims that different languages promote and restrict the kinds of ideas that people can develop and understand.
Human grammar is an example of a “discrete combinatorial system.” A finite number of discrete elements (in this case, words) are sampled, combined, and permuted to create larger structures (in this case, sentences) with properties that are quite distinct from those of their elements. He quotes William Von Humboldt saying language “makes infinite use of finite media.” By this he means that words, phrases, and sentences are made up of elements that can be combined and recombined in an infinite number of ways, always constrained from above by the innate structure of human grammar. Words are built up of elements called “morphemes.” Although the morphemes themselves are memorized and vary depending on language, they are combined following rigid rules which are not. The same type of unlearned rules apply to how phrases are constructed from words and sentences from phrases.
Although brain functions, including language, are distributed throughout the brain, there are areas in the brain, Pinker calls them “organs,” which clearly have grammatical functions. Damage to those brain areas can lead to very specific types of grammatical problems. Also, although he recognizes that specific traits are not generally controlled by single genes, studies show that changes in specific genes or lack of those genes can result in language dysfunction that can be passed down from parent to child.
Perhaps most interesting and important, from my point of view, is that people do not think in English, Mandarin, or Swahili. They think in what he calls “mentalese.” Babies and people who have grown up with no language clearly think. He hypothesizes that mentalese is universal and innate in humans.
“The Descent of Man” by Charles Darwin
Charles Darwin was a naturalist, biologist, and geologist, born in 1809 and died in 1882. In his discussion of language as instinct, Pinker quotes Darwin as writing:
Human language is an instinctive tendency to acquire an art. It certainly is not a true instinct, for every language has to be learned. It differs, however, widely from all ordinary arts, for man has an instinctive tendency to speak, as we see in the babble of our young children; while no child has an instinctive tendency to brew, bake, or write.
“What is an Instinct” by William James
William James was a psychologist and pragmatist philosopher, born in 1842 and died in 1910. James writes “Instinct is usually defined as the faculty of acting in such a way as to produce certain ends, without foresight of the ends, and without previous education in the performance.”
In “The Language Instinct”, Pinker discusses James’ position:
A language instinct may seem jarring to those who think of language as the zenith of the human intellect and who think of instincts as brute impulses that compel furry or feathered zombies to build a dam or up and fly south. But one of Darwin’s followers, William James, noted that an instinct possessor need not act as a “fatal automaton.” He argued that we have all the instincts that animals do, and many more besides; our flexible intelligence comes from the interplay of many instincts competing. Indeed, the instinctive nature of human thought is just what makes it so hard for us to see that it is an instinct.
He then quotes James as writing:
It takes…a mind debauched by learning to carry the process of taking the natural seem strange, so far as to ask for the why of any instinctive human act. To the metaphysician alone can such questions occur as: Why do we smile, when pleased, and not scowl? Why are we unable to talk to a crowd as we talk to a single friend? Why does a particular maiden turn our wits so upside-down? The common man can only say, “Of course we smile, of course our heart palpitates at the sight of the crowd, of course we love the maiden, that beautiful soul clad in that perfect form, so palpably and flagrantly made from all eternity to be loved!” And so probably does each animal feel about the particular things it tends to do in presence of particular objects. They, too, are a priori syntheses…
James also writes:
Nothing is commoner than the remark that Man differs from lower creatures by the almost total absence of instincts, and the assumption of their work in him by “reason.”...[But] the facts of the case are really tolerably plain! Man has a far greater variety of impulses than any lower animal; and any one of these impulses, taken in itself, is as “blind” as the lowest instinct can be; but, owing to man’s memory, power of reflection, and power of inference, they come each one to be felt by him, after he has once yielded to them and experienced their results, in connection with a foresight of those results…
…It is plain then that, no matter how well endowed an animal may originally be in the way of instincts, his resultant actions will be much modified if the instincts combine with experience, if in addition to impulses he have memories, associations, inferences, and expectations, on any considerable scale…
…there is no material antagonism between instinct and reason…
“The Feeling of What Happens” by Antonio Damasio.
Antonio Damasio is a neuroscientist as USC best known for his books on the neural basis of consciousness. This book in particular is mostly about consciousness, but in the early part he talks about non-conscious precursors to self-awareness that are appropriate for this discussion. Damasio identifies what he calls a “proto-self” made up of non-conscious neurological and endocrine bodily functions that connect the brain and peripheral body and which allow maintenance of equilibrium in mechanical, biological, and chemical bodily systems, called “homeostasis.” As Damasio writes:
I have come to conclude that the organism, as represented inside its own brain, is a likely biological forerunner for what eventually becomes the elusive sense of self. The deep roots for the self, including the elaborate self which encompasses identity and personhood, are to be found in the ensemble of brain devices which continuously and nonconsciously maintain the body state within the narrow range and relative stability required for survival. These devices continually represent, nonconsciously, the state of the living body, along its many dimensions. I call the state of activity within the ensemble of such devices the proto-self, the nonconscious forerunner for the levels of self which appear in our minds as the conscious protagonists of consciousness: core self and autobiographical self…
…[The proto-self is] a collection of brain devices whose main job is the automated management of the organism's life. As we shall discuss, the management of life is achieved by a variety of innately set regulatory actions—secretion of chemical substances such as hormones as well as actual movements in viscera and in limbs. The deployment of these actions depends on the information provided by nearby neural maps which signal, moment by moment, the state of the entire organism. Most importantly, neither the life-regulating devices nor their body maps are the generators of consciousness.
Damasio’s description of the proto-self brings to mind the design of mechanical and chemical process engineering systems, which I have some familiarity with, although I am not a chemical, process, or mechanical engineer. The drawing below is a piping and instrumentation diagram from a groundwater treatment system which includes removal of floating petroleum.
This is not a system that I worked on myself and I recognize it is hard to read. On the drawing, pipes are shown as solid lines with arrows; pumps, heaters, compressors, and other devices are shown as icons; vessels and tanks are shown as rectangles, and valves are shown as bowtie shapes. Instruments including heat, pressure, fluid level, pH, flow rate, and other sensors are shown as circles connected to the system by signal lines shown a dashed lines with arrows. Not shown on the drawing is a programmable control box, a computer, which takes input from the instruments and, based on that input turns pumps and other equipment on or off; opens and closes valves, records operating data, and sets off alarms with the purpose maintaining system status within established operating parameters. I think this is a good analogy for the proto-self system Damasio describes.
Boy, this has gotten a lot longer than I intended. I’ve tried to cut back, but there are important things I didn’t want to leave out. I had intended to include a discussion of the following books:
- “How Emotions are Made” by Lisa Feldman Barrett
- “The Origin of Consciousness in the Breakdown of the Bicameral Mind” by Julian Jaynes
- “Surfaces and Essences: Analogy as the Fuel and Fire of Thinking” by Douglas Hofstadter and Emmanual Sander.
But I decided not to. Maybe I’ll bring them up later in the discussion.
So, down to work. I have presented some ideas about how the mind works from scientists I consider credible whose ideas make sense to me. I’d like to discuss what the proper approach to thinking about the mind is. I consider these good examples. My conclusion - the mind is not magical or even especially mysterious, although there is a lot we don’t know. Mostly it’s just a foundation of business-as-usual biology resulting in the very powerful and complex thinking, feeling, seeing, remembering, speaking faculties of the human beings we all are.
And please - no discussion of consciousness experience or awareness.
