Happy New Year 2025! To celebrate, here is an encore of what proved to be the most popular episode of 2024. This rerun combines episodes 30 and 31 into one epic journey towards the frontiers of human understanding. My guest is Donald Hoffman. Our topics are consciousness, cosmos, and the meaning of life. Enjoy! Original show notes Laws of physics govern the world. They explain the movements of planets, oceans, and cells in our bodies. But can they ever explain the feelings and meanings of our mental lives? This problem, called the hard problem of consciousness, runs very deep. No satisfactory explanation exists. But many think that there must, in principle, be an explanation. A minority of thinkers disagree. According to these thinkers, we will never be able to explain mind in terms of matter. We will, instead, explain matter in terms of mind. I explored this position in some detail in episode 17. But hold on, you might say. Is this not contradicted by the success of natural sciences? How could a mind-first philosophy ever explain the success of particle physics? Or more generally, wouldn't any scientist laugh at the idea that mind is more fundamental than matter? No — not all of them laugh. Some take it very seriously. Donald Hoffman is one such scientist. Originally working with computer vision at MIT's famous Artificial Intelligence Lab, Hoffman started asking a simple question: What does it mean to "see" the world? His answer begins from a simple idea: perception simplifies the world – a lot. But what is the real world like? What is “there” before our perception simplifies the world? Nothing familiar, Hoffman claims. No matter. No objects. Not even a three-dimensional space. And no time. There is just consciousness. This is a wild idea. But it is a surprisingly precise idea. It is so precise, in fact, that Hoffman's team can derive basic findings in particle physics from their theory.  A fascinating conversation was guaranteed. I hope you enjoy it.

Christof is a neurophysiologist and computational neuroscientist best known for his work on the neural basis of consciousness on which he worked with Nobel Prize winner Francis Crick for 24 years. He is the president and chief scientist of the Allen Institute for Brain Science in Seattle. Christof describes his passion in life as "to understand how I came to be in this wonderful, mysterious universe. Not so much me, personally, but me as a conscious, experiencing thing surrounding by other conscious organisms and trees, stars, and the sea." Over the last decade, he has worked closely with the psychiatrist and neuroscientist Giulio Tononi. Together they advocate for an Integrated Information Theory (IIT) of consciousness - often seen as a modern version of panpsychism that only ascribes consciousness to entities with some degree of irreducible cause-effect power. Christof is the author of the books Consciousness: Confessions of a Romantic Reductionist. , The Quest for Consciousness: A Neurobiological Approach, and Biophysics of Computation: Information Processing in Single Neurons. His forthcoming book, Then I am Myself the World, is due out in 2024. In Sentientist Conversations we talk about the two most important questions: “what's real?” & “who matters?” Sentientism is "evidence, reason & compassion for all sentient beings." The video of our conversation is ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠here on YouTube⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠. We discuss: 00:00 Clips! 01:09 Welcome - "My dog... Mr. Felix... a sentient being" - The dedication from Christof's forthcoming book "Then I Am Myself The World": "... to all fellow travellers on the river of time who howl, bark, cry, screech, whine, bellow, shriek, buzz, sing, speak or those without a voice - for it is only in compassion with all life that we can redeem ourselves." 03:52 Christof's Intro - Physicist turned neurobiologist - "I've always been fascinated by the question of #consciousness" 04:45 What's Real - Growing up in a devout Roman #catholic family, raised kids Catholic - "One thing that always irked me... the belief that my dogs... somehow didn't have a soul and wouldn't be resurrected... that always bothered me... whatever it is we all share" - "I lived in two worlds - like many scientists do. On Sunday you go to church and you pray... during the week, the rest of the time, you're a scientist - you try to explain everything using natural explanation... this split... I couldn't support any more" - "Progressively I lost my faith... I'm a naturalist... I try to explain everything... using natural laws" - A priest acknowledging that non-human animals are "parts of god's creation" and can suffer, but "they do not partake in the same way we do" - Human exceptionalism "many religions believe that humans are exceptional... we're in charge of the universe... everything gets subsumed under human demands - that struck me as wrong" - "Who has what faith - it's totally random - it depends where you were born and in which family you were born... how can this be true?" - JW: Topics that draw even some naturalists back towards the mystical: Origins & nature of the universe, life, humanity, consciousness... 13:47 What and Who Matters? 39:45 What are Consciousness and Sentience? 1:14:09 A Better World? 1:17:35 Follow Christof - christofkoch.com - Christof at the Allen Institute - Christof on Wikipedia ...and much more.

What links conscious experience of pain, joy, color, and smell to bioelectrical activity in the brain? How can anything physical give rise to nonphysical, subjective, conscious states? Christof Koch has devoted much of his career to bridging the seemingly unbridgeable gap between the physics of the brain and phenomenal experience. Consciousness: Confessions of a Romantic Reductionist --part scientific overview, part memoir, part futurist speculation--describes Koch's search for an empirical explanation for consciousness. Koch recounts not only the birth of the modern science of consciousness but also the subterranean motivation for his quest--his instinctual (if "romantic") belief that life is meaningful. Koch describes his own groundbreaking work with Francis Crick in the 1990s and 2000s and the gradual emergence of consciousness (once considered a "fringy" subject) as a legitimate topic for scientific investigation. Present at this paradigm shift were Koch and a handful of colleagues, including Ned Block, David Chalmers, Stanislas Dehaene, Giulio Tononi, Wolf Singer, and others. Aiding and abetting it were new techniques to listen in on the activity of individual nerve cells, clinical studies, and brain-imaging technologies that allowed safe and noninvasive study of the human brain in action. Koch gives us stories from the front lines of modern research into the neurobiology of consciousness as well as his own reflections on a variety of topics, including the distinction between attention and awareness, the unconscious, how neurons respond to Homer Simpson, the physics and biology of free will, dogs, Der Ring des Nibelungen, sentient machines, the loss of his belief in a personal God, and sadness. All of them are signposts in the pursuit of his life's work--to uncover the roots of consciousness. Christof Koch is Professor of Biology and of Engineering at the California Institute of Technology and Chief Scientific Officer of the Allen Institute for Brain Science in Seattle. He is the author of The Quest for Consciousness and other books. Learn more about your ad choices.

This show is sponsored by Numerai, please visit them here with our sponsor link (we would really appreciate it) http://numer.ai/mlst Prof. Karl Friston recently proposed a vision of artificial intelligence that goes beyond machines and algorithms, and embraces humans and nature as part of a cyber-physical ecosystem of intelligence. This vision is based on the principle of active inference, which states that intelligent systems can learn from their observations and act on their environment to reduce uncertainty and achieve their goals. This leads to a formal account of collective intelligence that rests on shared narratives and goals. To realize this vision, Friston suggests developing a shared hyper-spatial modelling language and transaction protocol, as well as novel methods for measuring and optimizing collective intelligence. This could harness the power of artificial intelligence for the common good, without compromising human dignity or autonomy. It also challenges us to rethink our relationship with technology, nature, and each other, and invites us to join a global community of sense-makers who are curious about the world and eager to improve it.

In episode 33 of the Quantum Consciousness series, Justin Riddle interviews Kelvin McQueen on his recent theory on how consciousness might collapse the wave function. Kelvin is a professor of philosophy at Chapman University who investigates the nature of consciousness and role it might play in quantum mechanics. The measurement problem in quantum mechanics is that there is a smoothly and deterministically evolving superposition that is abruptly “measured” and reduced to a finite physical state, but it is unclear what constitutes a measuring device. In collaboration with David Chalmers, Kelvin explores the hypothesis that the measurement device in quantum mechanics might be consciousness. However, consciousness is typically an ill-defined vague idea that does not produce any tangible upgrade to the mystery of what a measuring device is. Here, Kelvin uses the definition of consciousness from integrated information theory (IIT) by Giulio Tononi. Consciousness is the minimally reducible information state of a system, which is defined as a recurrent network of interconnected nodes that predict the next state of the system. According to Kelvin, this definition allows for testable predictions to be made regarding the role of consciousness. In the upgraded quantum IIT theory, the nodes are quantum bits (or qubits) and the edges are entanglement relationships. Thus, QIIT defines an interconnected quantum computer (of sorts…) as consciousness and this reduces the wave function. Furthermore, the collapse of the wave function is not instantaneous but instead is continuous, drawing from the continuous spontaneous localization theory of quantum mechanics. Altogether, these ideas present a picture where consciousness is integral to a fundamental description of the physical universe and might provide room for an expanded sense of self. In this interview, I interrupt intermittently to describe the relevant ideas with graphical representation and compare this model to the Orchestrated Objective Reduction model by Stuart Hameroff and Roger Penrose. There are some amazing new ideas that Kelvin McQueen describes in this episode, so be sure to check it out!

Nick talks to neuroscientist and writer Dr. Erik Hoel. Erik is a professor of biology at Tufts University. He received his PhD in neuroscience from the University of Wisconsin, where he studied under the sleep and consciousness researcher, Giulio Tononi. He did postdoctoral work at Columbia University, where he used information theory and other analytical tools to explore the biological basis of consciousness. He has come up with the so-called Overfitted Brain Hypothesis of dreaming, which explains the potential adaptive function of dreams by drawing analogies to techniques used to train Deep Neural Networks in the world of machine learning. Erik and Nick discuss the biology and phenomenology of dreams and sleep generally, including some of the various theories for why we sleep. They also discuss Deep Learning (on a very basic level) and Erik described the Overfitted Brain Hypothesis of dreaming. They also discuss fiction and the arts, including Erik's new novel and the potential evolutionary reasons for why humans create and consume fiction, as well as some technology-driven developments that are reshaping how we create and consume written work online.

En el día de hoy reflexionaremos sobre la conciencia, buscaremos ver de qué se trata y cuáles son las concepciones que se tienen actualmente sobre la misma. Te invito entonces a que te tomes unos minutos y reflexionemos sobre ello. DIME LO QUE PIENSAS ¿Qué opinas de lo escuchado? ¿Qué es la conciencia para ti? ¿Crees que nuestra conciencia es algo que se genera en el cerebro? ¿Qué piensas de la propuesta del psiquiatra Giulio Tononi acerca de que todo lo existente tiene algún grado de conciencia? ¿Te parece natural eso, o por el contrario, es una idea que no te convence? En el momento de la muerte, ¿perderemos conciencia de quienes somos? ¿Tú qué opinas? Cuéntame lo que piensas en un COMENTARIO.

The Combination Problem is widely considered to be the most serious difficulty facing panpsychism. The exact nature of the problem depends on your view of fundamental reality (the parts that are being combined) and the self (what is being formed through combination). We also discuss Galileo, the fusion view, Giulio Tononi’s Integrated Information Theory, and a few other related issues.

One in a series of talks from the 2019 Models of Consciousness conference. Sean Tull Department of Computer Science, University of Oxford Integrated Information Theory (IIT), developed by Giulio Tononi and collaborators, has emerged as one of the leading scientific theories of consciousness. At the heart of IIT is an algorithm which, based on the level of integration of the internal causal relationships of a physical system in a given state, claims to determine the intensity and quality of its conscious experience. However, IIT is known to possess several technical problems, and is only applicable to simple classical physical systems. To be treated as fundamental, it should ideally be extended to more general physical theories. In this work, we investigate the formal structure of IIT, and define a notion of generalised integrated information theory in order to address these problems. Formally such a theory specifies a mapping from a given theory of physics to one of conscious experience, each satisfying minimal conditions needed for the IIT algorithm. In particular we show how a generalisation of IIT may be constructed from any suitable physical process theory, as described mathematically by a symmetric monoidal category. Specialising to classical processes yields IIT as usually defined, while restricting to quantum processes yields the recently proposed Quantum IIT of Zanardi et al. as a special case. Filmed at the Models of Consciousness conference, University of Oxford, September 2019.

One in a series of talks from the 2019 Models of Consciousness conference. Jonathan Mason Mathematical Institute, University of Oxford Over recent decades several complementary mathematical theories of consciousness have been put forward including Karl Friston’s Free Energy Principle and Giulio Tononi’s Integrated Information Theory. In contrast to these, in this talk I present the theory of Expected Float Entropy minimisation (EFE minimisation) which is an attempt to explain how the brain defines the content of consciousness up to relationship isomorphism and has been around since 2012. EFE involves a version of conditional Shannon Entropy parameterised by relationships. For systems with bias due to learning, such as various cortical regions, certain choices for the relationship parameters are isolated since giving much lower EFE values than others and, hence, the system defines relationships. It is proposed that, in the context of all these relationships, a brain state acquires meaning in the form of the relational content of the associated experience. In its simplest form involving only “primary relationships” EFE minimisation can also be considered as a generalisation of the initial topology (i.e. weak topology). For us the family of functions involved are the typical (probable) system states, the common domain of these functions is the set of system nodes (e.g. neurons, tuples of neurons or larger structures) and the common codomain is the set of node states. In the case of the initial topology a topology is already assumed on the common codomain and the initial topology is then the coarsest topology on the common domain for which the functions are continuous. In our case no structure is assumed on either the domain or codomain. Instead EFE minimisation simultaneously finds structures (for us weighted graphs, but topologies could in principle be used) on both the domain and codomain such that the functions are close (in some suitable sense) to being continuous whilst avoiding trivial solutions (such as the two element trivial topology) for which arbitrary improbable functions (system states) would also be continuous. Thus we find the primary relational structures that the system itself defines. In this context objects (visual and auditory) are present and EFE then extends to secondary relationships between such objects by involving correlation for example. To aid application of the theory, computationally cheaper surrogates for EFE are being developed. Filmed at the Models of Consciousness conference, University of Oxford, September 2019.

I neuroscienziati Giulio Tononi e Chiara Cirelli ci parlano di coscienza e di sonno

El por qué necesitamos dormir es claro, al menos según nos lo hace saber el cuerpo. Si no lo hacemos nos sentiremos cansados, irritables, con un humor de perros y con el problema añadido de que nuestro cerebro no funciona tan bien como quisiéramos: estaremos distraídos y como en medio de una nebulosa. Pero, ¿qué ocurre durante el dormir que hace que la situación se invierta y nos sintamos como nuevos después de un tiempo dedicados a ello? Entre las múltiples explicaciones del por qué dormimos, o mejor, por qué nos pasamos un tercio de nuestro tiempo “desperdiciado” entregados a una actividad que podríamos usar para otros fines, está la presentada por dos estudiosos del campo, Giulio Tononi y Chiara Cirelli. Ellos han venido consolidando una propuesta que han llamado la Hipótesis de la Homeostasis Sináptica. La explicamos en este podcast.

In our Cerebrum article, “The Sleeping Brain,” sleep researchers Chiara Cirelli and Giulio Tononi write about what happens inside our brains when we sleep. In our related podcast with Cirelli, M.D., Ph.D., a professor in the Department of Psychiatry at the University of Wisconsin, the sleep researcher talks about the difference between sleep and rest, the impact of sleep on memory, different sleeping habits, and the ties between nutrition and sleep. She also tells us what we’ve learned from sleep research and what we still need to know.

In this episode we interview Giulio Tononi, professor of psychiatry and neuroscience at the University of Wisconsin, on his theory of consciousness: Integrated Information Theory.
