Robert Berezin - Do Lower Life Forms and Inanimate Matter have Consciousness?

 

Robert Berezin is the author of Psychotherapy of Character: The Play of Consciousness in the Theater of the Brain (2013). This is from his personal blog - a post that offers a basic outline of his views on consciousness inspired by a video on panpsychism and complexity theory.

His views  are very close to my own, as far as I can tell from this post.

Do Lower Life Forms and Inanimate Matter have Consciousness?

images-1

Regarding the question whether consciousness is a property of animal brains vs. pansychism I come down 100% that consciousness exists solely as a brain function that is created by the limbic cortex. Pansychism is the belief that all life forms, and even molecular, atomic, and sub atomic particles have consciousness. Neil Theise, MD, makes the case for pansychism in his brilliant video “Complexity Theory & Panpsychism”. His illumination of fractals, and the centrality of interactions with the environment throughout the quantum levels going through invertebrates, single celled organisms, DNA, molecules, atoms, and subatomic particles is illuminating. I agree with all of his observations with one major exception.

I differ from his conclusion that they have sentience and consciousness. Sentient means capable of feeling. It comes from the Latin sentientemfeeling, and sentire – to feel. It came to mean conscious in 1815. Theise believes that an organism or particle has sentience because it has interactive relatedness with its environment. He claims that they ‘sense’ other particles which implies consciousness. I will present my understanding of sentience and consciousness. Then I will address how it is a fantasy to attribute consciousness to automatic functioning and environmental adaptation.
Human consciousness begins when an infant is approximately six weeks old. Its development begins with the fetal limbic system. The function of the fetal amygdala and limbic system is to map the survival interactions with the maternal environment. This brain circuitry links the body, hormones, subcortical brain, and the cortex—the amygdala for impulses of fear and pleasure; the hippocampus for gluing memories; the cingulate gyrus for attention and autonomic functions, such as heart rate and blood pressure; the hypothalamus for regulating the autonomic nervous system; and the thalamus, the relay station from the sub cortex.

The morphogenesis of the limbic system is progressive and continues in the newborn. At six weeks old, the newborn’s foundational appetites and rudimentary emotions morph a sufficiently high level of order to crystallize into a feeling of tenderness and sweetness. This constitutes the cohered feeling of the being of the baby. Yesterday there was no feeling of the baby. And suddenly it is here. Yesterday, he was simply an infant. Today, he is a human being. This ‘feeling of the being’ is a synthetic creation of extremely high levels of order in the limbic cortex which has been maturing through fetal life and the first six weeks after birth, during which the infant continues to map his survival environment with his mother.

And so it begins. Consciousness is born. The baby is now a sentient being. The ‘feeling’ of the baby is a synthetic persona created by the limbic cortex. This ‘self’ has no representational form. It is not knowable through the senses, thinking, or imagination. It cannot be seen. It is not an idea. It does not lend itself to being understood or comprehended. It only touches and is touched by feeling. The litmus test for the presence of this ‘feeling’ is that the mother (and others) are now touched by the presence of a tender feeling from the baby. Prior to this, the mother is predisposed to love her baby, and does, but there is no actual feeling relatedness. Then everything changes and she does feel him. It is analogous to the appearance of the embryonic heart. At one point there is no heart. And then it is there beating and pumping blood. At one point there is no feeling of the being and then it coalesces and there it is.

This is the beginning of consciousness, which is organized as a rudimentary play in the theater of the brain. This play is composed of a non-representational feeling persona of the baby in relationship with a non representational feeling persona of the mother, also a synthetic creation of the limbic cortex. Over the next three years higher and higher levels of symbolic form develop in the limbic cortex. When sufficiently mature, the personas then have form as representational images of self and others. This is the way we ordinarily know ourselves. However, even though the original ‘being’ of the baby is supplanted, its mapped circuits remain throughout life as the agency that generates the feeling of our being. It is the anchor of our loving. It is the quiet voice inside of us. It is our innocence. It is the source of our creativity. It is the source of our conscience. It is the fountain of our aliveness. None of this is mystical or magical. It is just the way consciousness is organized in the brain.

Consciousness is anchored in feeling – judgment, thinking, and relatedness are all anchored in feeling. Antonio Damasio illuminates this in his brilliant book, Descartes’ Error, Emotion, Reason, and the Human Brain. The rest of the body operates automatically, autonomically through the subcortical brain and has no consciousness – the uterus, the liver, intestines, etc. They function responsively, but they are not conscious and have no consciousness. Like Dr. Theise, I discuss the life functions of an ameba in chapter five of my book. There is certainly a distinction between an alive organism and inert matter. I agree that there is rudimentary ‘isness’ in the ameba and all life forms. The live ameba exercises its life functions and reproduces under the directions of its DNA. It is different from a dead thing. If it dies, then it no longer ‘is’. However, the ameba has a discrete repertoire of actions that it exercises automatically in relation to its environment. Even though it is alive. It is an automaton. It operates purely automatically, like our liver. It has no brain. It has no intention. It has no self awareness. Aliveness, ‘isness’ does not mean there is consciousness. There is no limbic-cortex to synthesize a feeling-being. Consciousness is the result of evolution. It emerged as an adaptational creation of the brain to interact effectively with the salient environments of the organism, and was selected for.

To attribute sentience to automatic functioning is the result of speculative imagination. And there is no actual evidence that this true. There is no evidence that an ameba has consciousness. Similarly, trees, clams, grass, worms, lobsters operate their life functions with a larger repertoire of automatic actions. But they too have no consciousness. You can physically touch a tree but it does not feel you. You can take a hatchet to a tree and it employs self preservative mechanisms to seal off the wound. But these are automatic processes. There is no consciousness.

I am by no means an expert on ant colonies and bee hives. And I certainly understand that they operate in many ways as if they are one organism. Nonetheless, their complex group behavior does not imply that they are anything but complicated automaton-drones surviving and replicating. It remains a leap to attribute consciousness to their organized behavior. Richard Dawkins in the “Selfish Gene” repeatedly says the attribution of selfishness to a gene is a device, and it in no way implies that they actually have consciousness. Nonetheless people leap to the false conclusion that genes are sentient. They are not. When sixty million human sperm are injected into a female and they race to mate with an egg cell floating in the fallopian tube, this is just automaton activity. The sperm certainly are in a competitive race. This is what they do. But they are not thinking, “Oh my god, Larry is catching up with me, I better step on it.”

Mammals and birds do have limbic cortical brains. Although, different from ours, they have consciousness. They are sentient beings. Furthermore, when considering non-alive entities like DNA and molecules and atoms, we cannot attribute sentience. Dr. Theise conclusion that they are ‘sensing’ other particles is a fantasy leap. Sub atomic particles don’t ‘sense’ things. They automatically react to their environment according to the laws of physics. Theise goes one step further which raises a caution flag to my mind. He utilizes string theory. String theory is very attractive to many people. But it has no actual proof. Just because one can conceive of things outside our experience or imagine other dimensions, does not make them true. Such believed imaginings are not any different from other beliefs which have no proof. To then operate as if string theory is true and to derive implications leads to the construction of a misleading house of cards. Higgs-Bosons are valid, quantum foam has no evidence whatsoever.

All of existence formed from the collision of randomness and order. Both inanimate particles as well as life forms evolve and take hold as a result of natural selection and the laws of physics. The idea that all matter has sentience has no foundation. Its like a modern form of Lamarckism. Everything in the universe interacts with an environment. It is no more credible that evolution comes from acquired characteristics than the idea that everything has consciousness. This inevitably leads to the conclusion that everything has Mind, and then that there is a universal Mind.

Why Ray Kurzweil is Wrong: Computers Won’t Be Smarter Than Us Anytime Soon

Recently, I shared an article from George Dvorsky called "You Might Never Upload Your Brain Into a Computer," in which he outlined a series of reasons for his position:
1. Brain functions are not computable
2. We’ll never solve the hard problem of consciousness
3. We’ll never solve the binding problem
4. Panpsychism is true
5. Mind-body dualism is true
6. It would be unethical to develop
7. We can never be sure it works
8. Uploaded minds would be vulnerable to hacking and abuse
While I disagree with at least two of his points (I am not convinced panpsychism is true and I am VERY skeptical of mind-body dualism), I applaud the principle of it.

Likewise, this recent post from John Grohol at Psych Central's World of Psychology calls out futurist Ray Kurzweil on his claims around computer sentience, i.e., the singularity.

Why Ray Kurzweil is Wrong: Computers Won’t Be Smarter Than Us Anytime Soon

By John M. Grohol, Psy.D.



“When Kurzweil first started talking about the “singularity”, a conceit he borrowed from the science-fiction writer Vernor Vinge, he was dismissed as a fantasist. He has been saying for years that he believes that the Turing test – the moment at which a computer will exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human – will be passed in 2029.”

Sorry, but Ray Kurzweil is wrong. It’s easy to understand why computers are nowhere near close to surpassing humans… And here’s why.

Intelligence is one thing. But it’s probably the pinnacle of human narcissism to believe that we could design machines to understand us long before we even understood ourselves. Shakespeare, after all, said, “Know thyself.”

Yet, here it is squarely in 2014, and we still have only an inkling of how the human brain works. The very font of out intelligence and existence is contained in the brain — a simple human organ like the heart. Yet we don’t know how it works. All we have are theories.

Let me reiterate this: We don’t know how the human brain works.

How can anyone in their right mind say that, after a century of study into how the brain operates, we’re suddenly going to crack the code in the next 15 years?

And crack the code one must. Without understanding how the brain works, it’s ludicrous to say we could design a machine to replicate the brain’s near-instantaneous processing of hundreds of different sensory inputs from dozens of trajectories. That would be akin to saying we could design a space craft to travel to the moon, before designing — and understanding how to design — the computers that would take the craft there.

It’s a little backwards to think you could create a machine to replicate the human mind before you understand the basics of how the human mind makes so many connections, so easily.

Human intelligence, as any psychologist can tell you, is a complicated, complex thing. The standard tests for intelligence aren’t just paper-and-pencil knowledge quizzes. They involve the manipulation of objects in three-dimensional spaces (something most computers can’t do at all), understanding how objects fit within a larger system of objects, and other tests like this. It’s not just good vocabulary that makes a person smart. It’s a combination of skills, thought, knowledge, experience and visual-spatial skills. Most of which even the smartest computer today only has a rudimentary grasp of (especially without the help of human-created GPS systems).

Robots and computers are nowhere close to humanity in approaching its intelligence. They are probably around an ant in terms of their proximity today to “outsmarting” their makers. A driving car that relies on other computer systems — again, created by humans — is hardly an example of computer-based, innate intelligence. A computer than can answer trivia in a game show or play a game of chess isn’t really equivalent to the knowledge that even the most rudimentary blue-collar job holder holds. It’s a sideshow act. A distraction meant to demonstrate the very limited, singular focus computers have historically excelled at.

The fact that anyone even needs to point out that single-purpose computers are only good at the singular task they’ve been designed to do is ridiculous. A Google-driven car can’t beat a Jeopardy player. And the Jeopardy computer that won can’t tell you a thing about tomorrow’s weather forecast. Or how to solve a chess problem. Or what’s the best way to retrieve a failed space mission. Or when’s the best time to plant crops in the Mississippi delta. Or even the ability to turn a knob in the right direction in order to ensure the water turns off.

If you can design a computer to pretend to be a human in a very artificial, lab-created task of answering random dumb questions from a human — that’s not a computer that’s “smarter” than us. That’s a computer that’s incredibly dumb, yet was able to fool a stupid panel of judges judging from a criteria that’s all but disconnected from the real world.

And so that’s the primary reason Ray Kurzweil is wrong — we will not have any kind of sentient intelligence — in computers, robots, or anything else — in a mere 15 years. Until we understand the foundation of our own minds, it’s narcissistic (and a little bit naive) to believe we could design an artificial one that could function just as well as our own.

We are in the 1800s in terms of our understanding of our minds, and until we reach the 21st century, computers too will be in the 1800s of their ability to become sentient.
