Most of us assume the world we perceive is simply out there. But neuroscientists increasingly argue the reality we see is a "controlled hallucination"; a user-interface, a best guess created by our brains — not reality itself. Join one of the world's most cited neuroscientists, Karl Friston, and Closure theorist and philosopher Hilary Lawson, as they explore the idea that our brains construct reality, and ask what this means for our understanding of the world and ourselves.

"The most influential neuroscientist alive today." — Sean Carroll

"Lawson's Closure theory is perhaps the first non-realist metaphysics." — Don Cupitt
