Antonio Damasio, neuroscientist: “Artificial organisms can have consciousness, but not like humans” | Science | EUROtoday

Antonio Damasio has spent three a long time dismantling Descartes’ unique concept that the thoughts and physique are separate entities. Descartes’ errorwhich this Lisbon researcher revealed in 1994, is already a traditional of neuroscience and established the creator as probably the most influential scientists in his area. 30 years later, and after having received every kind of awards and doctorates for the sake of honorDamasio goes additional: in his new e-book, Natural intelligence and the logic of consciousness (Destination), The 81-year-old neuroscientist not solely argues that we can not perceive consciousness with out the physique, however that, opposite to what’s often assumed, we don’t really feel as a result of we’re aware, nevertheless it occurs precisely the opposite approach round: to be aware, we should first really feel. The reply to the everlasting thriller of consciousness, Damasio maintains, will not be within the cerebral cortex—as was thought—however in older buildings, and that distinction has profound implications for understanding what makes us human and what synthetic intelligence lacks to be self-aware. Although, he warns, he might not at all times lack it.

“Five years ago I would not have been able to write this book,” Damasio acknowledges, throughout a dialog this Monday with EL PAÍS in Madrid. The neuroscientist, who directs the Brain and Creativity Institute on the University of Southern California in Los Angeles, solutions all questions with enthusiasm and vehemence, besides when requested about one factor: Donald Trump’s authorities and its assault on science: “It is a very difficult moment,” he merely shares.

Ask. You title your e-book with the phrases “natural intelligence.” Why the emphasis on pure? Is it due to the second we live with respect to synthetic?

Answer. Absolutely. I needed to make it very clear that synthetic intelligence is a really fascinating advance, however it’s a growth that comes from pure intelligence. We invented synthetic intelligence; Artificial intelligence didn’t invent us. There is a primary worth that’s our personal intelligence, our personal creativity and, from that pure intelligence, we develop consciousness, which is a really related challenge.

P. And why is it so related?

R. Consciousness is what permits us to be full people. We can’t be with out having this notion of who and the way we’re. Consciousness is what permits our minds to belong to a specific physique. I’m aware proper now as a result of I do know that my thoughts is in my physique, and never in yours. The union of thoughts and physique is essential. It is what offers us the individuality that’s solely attainable as soon as we’re aware.

P. You have lengthy argued towards mind-body dualism. In this e-book he emphasizes that emotions require each the mind and the physique, that are a part of a hybrid course of. Is that so?

R. It is completely hybrid. Our nervous system permits us to attach with our physique. Our consciousness will not be one thing ethereal floating round; It is one thing that’s being manufactured by our nervous system inside our physique. And a very good a part of the essence of consciousness is, in actual fact, the data we now have of our personal physique at work. This e-book is the continuation of a piece spanning many a long time. Some of it has appeared in earlier books, nevertheless it enhances the data that has been offered in different books, as a result of it truly explains the mechanism by which consciousness could be acquired. It has to do with homeostatic sensations and the kind of nervous construction needed for this.

P. Tell us about it.

R. Homeostasis permits us to comprehend that sure guidelines should be revered for all times to proceed. Homeostatic sensations are, for instance, starvation, thirst, ache, feeling good, feeling unwell. All of those emotions are warning programs, they serve to warn us concerning the issues we’d like, like ingesting water or giving ourselves a break if we’re in ache. They alert us to what’s needed for all times to proceed. Therefore, we may see consciousness as the results of a sequence of alerts, sentinels that warn you that one thing is unsuitable or, conversely, that the whole lot is ok and, subsequently, you’ll be able to discover the world.

P. You elevate an fascinating query within the e-book. Are vegetation or timber aware? And the micro organism?

R. Bacteria haven’t any consciousness or emotions. And are you aware why? They should not have a nervous system. It could be stated that there’s solely consciousness in organisms which are advanced sufficient to have a nervous system, which is what permits them to have emotions and consciousness. Trees and vegetation are very advanced, they’ve life, and that life is related, however they don’t have consciousness. On the opposite hand, animals have a nervous system and are aware. They, after all, should not have the identical diploma of information, reminiscence, reasoning and language capability that we now have. But that does not imply they don’t seem to be conscious. They are very conscious.

P. Returning to synthetic intelligence, there are programs like AlphaFold which are managing to resolve issues that the pure intelligence of human beings has by no means been in a position to remedy. Is this a step in the direction of consciousness?

R. Excellent query. It is the central query within the present investigation. Will synthetic intelligence programs ever change into aware? I used to suppose very radically: no. And my argument is that synthetic intelligence organisms are created by us, however they don’t have life, and they don’t have life in society. They don’t dwell, however moreover, advanced pc programs should not have social relations with different pc programs. They are all particular person organisms that aren’t residing. Therefore, the chance of them creating consciousness may be very low. But, alternatively, it’s attainable, given the large ingenuity of people, to mimic sure circumstances. That’s why I’m extra cautious now; There could also be the opportunity of creating consciousness in synthetic organisms, nevertheless it is not going to be like human consciousness. It goes to be a unique sort of consciousness as a result of they don’t seem to be alive and they don’t have social relationships.

P. How would it not be completely different from human?

R. It is completely different in that we will really feel the state of our flesh, our physique. Consciousness has to do with sensations of well-being, ache, and discomfort. That is why it is extremely tough to think about {that a} creature that’s made from items of steel and wherein there isn’t a vulnerability has consciousness. We have a really completely different degree of complexity and we now have an exquisite factor which is the best way we dwell in society with others, the best way we detect that others can undergo and are susceptible like us and, subsequently, we create a complete… We are at all times dancing round others. And that’s what creates societies. We know that these societies are usually not good, simply go searching us. However, there may be that social connection.

P. How can this work on consciousness assist sufferers with problems equivalent to coma or vegetative state?

R. We now know that our consciousness is constructed from indicators that come from contained in the physique and that arrive via what is known as interoception, which is the best way of gathering info from contained in the physique. This offers us a option to deal with ailments that have an effect on the nervous system in these circumstances. The mind stem is the important thing to producing consciousness. Many individuals mistakenly thought it was the cerebral cortex, which is essential for our notion of the world and our creativeness, however it isn’t what offers us consciousness. Consciousness comes primarily from the data we now have of our physique at a given second.

P. Looking again from Descartes’ erroryour first e-book, how has your mind-set advanced in these thirty years?

R. I have never modified my thoughts about the truth that the thoughts comes from the physique. But once I wrote Descartes’ error I had no concept how the thriller of consciousness may very well be solved, and now I do. And I can say with some ensures that it doesn’t come from the cerebral cortex, however from less complicated methods of regulating life. And that may be very, essential.

P. And what are you engaged on proper now?

R. We are getting an increasing number of details about the kind of nerve cells which are important for gathering info from the physique. Because they’re very completely different from those we’re each utilizing proper now to grasp this dialog. To do this we have to have very refined neurons which have axons insulated by myelin and that, in actual fact, perform similar to how computer systems do digitally. However, the truth that, for instance, I really feel good speaking to you is because of neurons that should not have myelin and which are susceptible to their environment and that, in actual fact, perform extra like an analog system than a digital system. These are the issues we wish to discover now in our analysis. And we hope this distinction turns into even clearer. It may be very fascinating as a result of we return to what we talked about at the start concerning the title of this e-book: the programs we use to suppose are similar to synthetic intelligence. This is yet one more approach wherein our pure intelligence has already invented what synthetic intelligence is. This will not be autonomous in any respect. And, because of this, the phrase “natural” within the e-book is prime.
