Summary of Transcript:
The video discusses the possibility of virtual reality systems in the Future that are indistinguishable from physical reality, allowing humans to be put into simulations. The discussion then turns to the complex problem of consciousness: the mystery of how and why we experience subjective consciousness. The speaker, philosopher David Chalmers, explains that while science has successfully described human behavior, explaining consciousness is different because it involves emotional experience. He discusses his previous attempts at finding a purely physical explanation for consciousness but ultimately discarded them as they all had an unexplained mystery. He suggests that a strictly physical description can only explain the structure and dynamics of the physical system but cannot explain subjective experience.

Summary of Description:
David Chalmers, Professor of Philosophy and Neural Science at New York University and co-director of the Center for Mind, Brain, and Consciousness, explores the nature of reality and virtual reality in his latest book, Reality+: virtual worlds and the Problems of Philosophy. In a wide-ranging conversation, he discusses the complex problem of consciousness, the idea that consciousness is a fundamental law of nature, the foundations of simulation theory, the possibility of living a meaningful life in VR, and the use of avatars to play the roles of physical bodies in the digital world. Chalmers also compares VR to the famous “Experience Machine” thought experiment and muses on the Future of “techno philosophy.”

Exploring the Nature of Reality and Consciousness with Philosopher David Chalmers
Philosopher David Chalmers is known for his work on the nature of consciousness and the human experience. In his latest book, Reality+, Chalmers examines virtual reality and its impact on our understanding of reality and consciousness. In this conversation, we delve into some of the key ideas explored in his book.
The Hard Problem of Consciousness
Chalmers starts by discussing the complex problem of consciousness. This problem arises because we don’t know how physical processes in the brain give rise to subjective experiences. The question is, how do we get from neural activity to conscious experience?
Consciousness as a Fundamental Law of Nature
Chalmers suggests that we must treat consciousness as a fundamental property of nature. In other words, we should treat consciousness like a charge in physics – a virtual universe building block. Chalmers believes that by doing this, we might be able to uncover the fundamental laws that govern consciousness.
The Foundations of Simulation Theory
Chalmers also discusses simulation theory – the idea that we live in a computer simulation. He explores some arguments for and against this idea and concludes that it’s impossible to know whether we’re living in a simulation.
Is Reality Made of Information?
Chalmers also delves into the idea that reality might be made of the information. This idea has gained traction in recent years, particularly in quantum physics, but Chalmers suggests that we need to be careful not to conflate information with meaning.
How to Live a Meaningful Virtual Life
One of the most exciting topics Chalmers explores in his book is that we can live meaningfully in virtual reality. Chalmers argues that what happens in VR is accurate and that we can build our own lives in VR. He suggests that the avatar might eventually be able to replace the physical body in many ways.
The Philosopher’s Zombie
Another interesting idea that Chalmers explores is the philosopher’s zombie – a hypothetical being physically identical to a human being but lacking consciousness. Chalmers argues that the existence of philosopher’s zombies is logically possible, which means that consciousness must be something over and above physical processes.
Orderable States of Consciousness
Chalmers also discusses the idea of orderable states of consciousness – the idea that the universe has a limited set of possible configurations that give rise to conscious experience. Chalmers suggests that we might be able to find these orderable states and use them to manipulate and transform consciousness.
Zhuangzi and the Butterfly
Chalmers also touches on the story of Zhuangzi and the butterfly. This story explores the idea that we can never truly know whether what we’re experiencing is reality or a dream. Chalmers suggests that this story has relevance to our understanding of virtual reality.
The Experience Machine
Chalmers also explores the thought experiment known as the experience machine – a hypothetical machine that can simulate any experience. Chalmers argues that even if we could be hooked up to an experience machine, most people would choose not to because they value their experiences’ reality.
GPT3 and Deepfakes
Chalmers discusses the current state of AI and the potential for deepfakes – fake videos and images that are difficult to distinguish from reality. He suggests that we must be careful about these technologies’ power and their potential to manipulate our understanding of reality.
The Future of “Technophilosophy”
In closing, Chalmers discusses the Future of techno philosophy – the intersection of philosophy and technology. Chalmers suggests that new technologies, like VR and AI, will continue to challenge our understanding of reality and consciousness and that we need to approach these questions with a philosophical mindset.

“I think, therefore I am.” – René Descartes.
What is reality? What is the nature of consciousness? How do we know that what we are experiencing is based on fact and not a simulation?
These may seem like the kind of questions that you’d associate with modern concepts like The Matrix and simulation theory. Still, the fact is that every ancient philosophical tradition has wrestled with these problems in some form or another.
And with the advent of rich, complex VR worlds and the nascent metaverse, even more, philosophers are turning toward these deep questions of consciousness and the human experience.
One of the most exciting thinkers in this space is David Chalmers, Professor of Philosophy and Neural Science at New York University and co-director of the Center for Mind, Brain, and Consciousness.
In his latest book, Reality+: virtual worlds and the Problems of Philosophy, David investigates not only the nature of reality but how we should conceptualize virtual reality, the idea that we can live a meaningful life in VR, how we know there’s an external world, and much more.
We explore these topics in today’s wide-ranging conversation, covering everything from the complex problem of consciousness to the probability of living in a computer simulation.
You don’t have to be a student of philosophy to enjoy today’s conversation – especially if you’re as excited as I am about the possibilities being unlocked by virtual reality and the metaverse.

QUOTES:
“How does the water of neural firings in the brain turn into the wine of consciousness?” [05:45]
“I believe what we have to do for consciousness is something akin to what Maxwell did for a charge – treat consciousness as a fundamental property in nature and search for the fundamental laws that govern it.” [09:09]
“One of the basic questions in philosophy: Why is there something rather than nothing? Why is there anything in the universe? And it just looks like some things you must take as fundamental properties and laws. And that’s not wholly satisfying, but it looks like it’s the best we can do.” [32:39]
“I think the more we understand the connection between the brain and consciousness, the more capacities we’re going to find for both manipulation and transformation of consciousness.” [51:48]
“I do want to think you can have… a meaningful life in VR because what happens in VR is real – it’s not scripted. It’s not pre-programmed. You can build your own life in VR.” [1:08:23]
“I think at a certain point, the avatar can begin to play… many of the roles of the physical body. It’s as if you have two bodies, a physical body in the physical world and a digital body in the digital world.” [1:24:02]
