In this episode of the “Modern Wisdom” podcast, host Chris Williamson interviews Anil Seth, a renowned neuroscientist, about the problem of consciousness and how our brains create our conscious reality. They delve into the complexities of perception, the nature of the self, and the role of consciousness in our everyday experiences.
The problem of consciousness has been a longstanding challenge for philosophers and neuroscientists. It involves understanding how our subjective conscious experiences arise from the physical processes of the brain. Perception, which is often divorced from objective reality, plays a crucial role in shaping our conscious reality.
One theory suggests that the brain is a prediction machine, constantly generating predictions about the world and updating them based on sensory information. Different conscious experiences can be seen as different predictions made by the brain. Progress in understanding the properties of consciousness may eventually help resolve the hard problem of consciousness.
The self is a central aspect of consciousness but is often overlooked in discussions about consciousness. It is a complex construct that encompasses various levels, including basic existence, emotions and moods, experiences of the body, and social identity. Understanding the self and its role in consciousness is crucial for unraveling the mysteries of conscious experience.
Our experiences of the world and of the self are not direct reflections of an objective reality. Instead, our brains actively interpret sensory information to make sense of the world. The brain’s predictions about what causes sensory signals shape our conscious experiences. Perception is a process that helps us navigate and survive in a complex and uncertain environment.
The question of animal consciousness and how to measure it is a topic of ongoing debate. Different animals have different sensory abilities, and their experiences of the world are unique to their ecological niche. The mirror self-recognition test and responsiveness to pain are two methods used to assess animal consciousness, but there is no consensus on which animals are conscious and to what extent.
Changing the brain in a specific way can reliably and predictably alter consciousness. Psychedelics and meditation are two tools that can induce profound changes in conscious experience. However, it’s important to recognize that these altered states of consciousness should not be taken at face value as the true version of reality. They provide insights into the malleability and constructed nature of conscious experience.
The problem of consciousness continues to fascinate and challenge scientists and philosophers alike. By exploring the complexities of perception, the nature of the self, and the role of consciousness in our everyday experiences, we can gain a deeper understanding of the mysteries of conscious reality. Through ongoing research and inquiry, we may eventually unravel the secrets of consciousness and gain new insights into the nature of our own existence.
