Anil Seth (born 11 June 1972) is a British neuroscientist, author, and professor of Cognitive and Computational Neuroscience at the University of Sussex, where he co-directs the Sussex Centre for Consciousness Science. He is a leading figure in the scientific study of consciousness, best known for his work on perception as a "controlled hallucination" and his popular science writing.
Key Scientific Contributions and Theories
"Controlled Hallucination" Theory: Seth posits that what we perceive as reality is actually a "controlled hallucination" generated by the brain, rather than a direct, passive readout of the outside world. He suggests the brain is a prediction machine that constantly generates hypotheses about the causes of sensory input, updating them based on new data.
The "Real Problem" of Consciousness: Instead of focusing on David Chalmers' "hard problem" (how/why physical processes produce subjective experience), Seth advocates for addressing the "real problem". This involves predicting, explaining, and controlling the properties of consciousness by linking them to specific, observable brain mechanisms.
Materialist/Physicalist Approach: Seth supports the view that consciousness is an emergent property of the brain's physical, biological mechanisms.
The Self as a "Construction": He argues that the sense of "self" is not a central entity in the brain, but rather a collection of perceptions—an embodied, perspectival, and narrative construction aimed at keeping the organism alive.
