Joining the discussion are Anil Seth, a neuroscientist passionate about consciousness, anthropologist Tanya Luhrmann, and biologist Rupert Sheldrake, known for his unorthodox ideas. They explore whether consciousness stems solely from the brain or transcends it. The conversation delves into personal experiences versus cultural influences on perception and delves into fascinating topics like tulpamancy, the concept of the extended mind, and the historical evolution of consciousness. Together, they challenge conventional views and inspire new ways of understanding our minds.
The unique debate format features only heretics challenging traditional views on consciousness rather than defending established beliefs.
Anil Seth argues that consciousness is a complex frontier, shaped by internal processes rather than simply arising from brain activity.
Tanya Luhrmann emphasizes the cultural dimensions of consciousness, highlighting how societal practices influence individuals' perceptions of their thoughts as external entities.
Rupert Sheldrake introduces a panpsychist perspective, proposing that consciousness exists beyond humans and is inherent in all self-organizing systems.
The discussion on AI raises ethical concerns regarding the potential for machines to achieve consciousness and the responsibilities that come with it.

Structure of the Debate
The structure of the debate is uniquely designed, departing from traditional formats. Typically, debates feature a defender of established beliefs, a heretic, and a mediator. However, this particular debate presents only heretics who will interrogate long-held scientific assumptions. The objective is not just to express disagreement but to delve into the implications and consequences of these divergent views.
Experiences and Their Implications
The way people accept or reject ideas often hinges on the perceived impact those ideas may have on their existing worldview. Acceptance may necessitate the abandonment of beliefs that individuals are hesitant to relinquish. Thus, the ensuing exploration focuses on why different opinions exist and what is fundamentally at stake. This understanding is vital as it can redefine how we comprehend ourselves and our interactions with the world.
Consciousness: A Modern Frontier
Anil Seth emphasizes consciousness as a significant frontier in modern science, noting that anesthetic experiences demonstrate the complex nature of consciousness. His assertion suggests that the brain should not be viewed merely as a biological computer, as human experience is rich and multifaceted. Conscious experiences are defined, exploring how experiences differ with factors like time and absence of sensory input. This challenges traditional perspectives about consciousness and pushes for a deeper understanding of human awareness and experience.
Hard Problems of Consciousness
The podcast discusses the so-called 'hard problem of consciousness,' which highlights the struggle to comprehend how conscious experiences arise from neural activity. The prevailing assumption within neuroscience is that consciousness stems from physical processing in brains, yet no solid explanation elucidates this connection. Various theories have been proposed and researched, reflecting a renaissance in the scientific study of consciousness. While no consensus exists yet, the ongoing inquiry promises progress in addressing the complexities surrounding consciousness.
The Predictive Brain
Seth presents a theory suggesting that the brain operates as a prediction machine, where our experiences are essentially well-informed guesses rather than straightforward reactions to sensory input. This theory posits that consciousness emerges from actively constructing our perceptions of the world, rather than passively receiving information. The implications extend to recognizing that our conscious experiences are shaped significantly by internal processes rather than merely external stimuli. This perspective could fundamentally reframe discussions about the nature of perception and reality.
Cultural Perspectives on Consciousness
Tanya Lerman shares her anthropological insights into how individuals across various cultures often report experiencing their thoughts as external entities. These experiences, sometimes perceived as communication from a divine presence, have significant implications on people's lives. Cultural practices and rituals can facilitate these experiences, suggesting a complex interplay between societal constructs and individual consciousness. This challenges conventional understandings of mental processes and underscores the significance of cultural context in shaping consciousness.
Panpsychism and Conscious Experience
Rupert Sheldrake posits a panpsychist view where consciousness is not purely a product of brains but a fundamental aspect of all self-organizing systems. He suggests that consciousness may extend beyond human experience, proposing that animals and even natural elements possess varying degrees of consciousness. This outlook challenges the traditional, reductionist scientific perspective, advocating to broaden the understanding of consciousness to encompass the entire universe. Such a view pushes the boundaries of how we perceive and relate to consciousness in the natural world.
AI and Consciousness Debate
The discussion transitions to artificial intelligence and the potential for machines to develop consciousness. Seth articulates skepticism about the notion that AI could attain consciousness, underscoring the need for an understanding based on biological systems. The ethical implications of creating conscious machines raise significant concerns about moral responsibilities. This highlights a need to critically evaluate contemporary narratives surrounding artificial intelligence within the broader framework of consciousness studies.
Consciousness as an Evolving Concept
The podcast concludes with reflections on the evolving nature of consciousness studies and the importance of maintaining an open dialogue. Emphasizing the historical progression of understanding consciousness, participants advocate for the inclusion of diverse perspectives. Ongoing research and discourse are seen as crucial steps toward unraveling the complexities associated with consciousness. This collaborative exploration aims to integrate scientific rigor with experiential and cultural insights for a more nuanced understanding of consciousness.
Do conscious experiences happen both within and outside the brain, and can science solve the 'hard problem' of consciousness?
At the 2023 Holberg Debate, Tanya Luhrmann, Anil Seth and Rupert Sheldrake met to explore the deep scientific and philosophical mystery of consciousness. The debate was chaired by David Malone.
