Dr. Shamil Chandaria explores predictive processing and its impact on perception and spiritual practice. Topics include Bayesian models, priors, Buddhist philosophies, and homeostatic control. The conversation delves into how we construct reality and the transformative power of contemplative practices in reshaping worldviews for a fulfilling life.
Predictive processing theory challenges traditional sensory processing hierarchies, indicating active brain construction of generative models for efficient environmental navigation.
Contemplative practices deconstruct rigid beliefs to build new, positive priors that support well-being and compassion.
Deep dives
Predictive Processing in the Brain
The brain's traditional account of processing sensory information up a hierarchy to understand the environment has been challenged by predictive processing theories. Instead of passively receiving information, the brain actively creates a generative model of the world and compares it with sensory data, adjusting to minimize the difference. This two-way process, grounded in principles like Bayes' Theorem, allows the brain to efficiently navigate through the environment without needing infinite computational resources.
The Impact of Priors on Perception
Priors, acquired through Bayesian updating and evolution, shape how we perceive and interact with the world. From basic priors like blood sugar levels to learned priors about objects, these beliefs influence our understanding of reality and guide our actions. By recognizing and updating these priors, individuals can adapt their perceptions and responses to align with a more accurate representation of the world.
Deconstructing and Reconstructing Concepts
Contemplative practices focus on deconstructing rigid concepts and perceptions to realize the impermanent and constructed nature of experiences. By breaking down these mental constructs into sensory details, individuals can detach from rigid beliefs, leading to a deeper understanding of the self and reality. The process of reconstruction involves building new, positive priors that support well-being and align with a more harmonious and compassionate worldview.
Liberating Insight through Cognitive Framework
The cognitive framework of predictive processing offers insights into how individuals can navigate and optimize their perception of reality to reduce suffering and enhance well-being. By embracing the impermanent nature of phenomena and cultivating high-level priors like 'Amor Fatih', individuals can construct stable and self-reinforcing belief systems that promote resilience, fulfillment, and a deeper sense of harmony with the world.
Meditation is about getting to grips with the way we construct the world.
Today we are delighted to welcome Dr Shamil Chandaria from the Centre for Eudaimonia and Human Flourishing at University of Oxford.
An expert in his field, Shamil leads us on an investigative journey into predictive processing and its implications for perception and spiritual practice.
Touching on Bayesian models, priors, dereification, Buddhist philosophies, Amor Fati and homeostatic control - our conversation today is packed with delicate and refined observations on the different ways we construct reality.
