Does consciousness arise from the brain? | Donald Hoffman challenges Hannah Critchlow

Introduction

The speaker introduces the topic of consciousness and relates it to morality. They discuss how our moral behavior is governed by specific regions and circuits in the brain, as well as genes inherited from our parents.

Neural Correlates of Conscious Experience

The speaker discusses their own research on the neural correlates of conscious experience, specifically related to motion perception. They mention that there are many neural correlates with consciousness, but no scientific theory can explain how they give rise to conscious experiences.

  • There are currently no physicalist theories that can explain how neural activity gives rise to conscious experience.
  • Theories such as integrated information theory and orchestrated collapse of microtubules theory cannot provide a specific example of a conscious experience.
  • The lack of physicalist theories means we need to explore new directions in understanding consciousness.

Evolution and Perception

The speaker discusses the idea that our perceptions are more like a virtual reality shaped by evolution for adaptive behavior rather than showing us objective reality.

  • Fitness payoff functions do not have any information about the structure of objective reality, so they could not shape us to see the truth.
  • Our perceptions guide adaptive behavior but do not necessarily show us objective reality.

Donald Hoffman and Hannah Critchlow debate the origins of consciousness. This excerpt was taken from "The key to consciousness," featuring Sam Coleman, Donald Hoffman, and Hannah Critchlow. Joanna Kavenna hosts.

He is making waves with a new theory suggesting that, instead of presenting reality as it "really is", our perception is like a desktop interface enabling us to use reality effectively. Named as one of the ten leading "communicator scientists" in the UK by the Science Council, Hannah Critchlow is an internationally-acclaimed neuroscientist with a background in neuropsychiatry. The Institute of Art and Ideas features videos and articles from cutting edge thinkers discussing the ideas that are shaping the world, from metaphysics to string theory, technology to democracy, aesthetics to genetics.
