Qualia And Quantum Physics
Our consciousness is the inner semantic space where the signals coming from the physical world, both inside and outside the body, are 'processed' by the brain and take the form of feelings, sensations, and meanings, i.e., of qualia. Qualia refer to what 'it feels like' when a sensation or a feeling emerges within our consciousness. Note that the nature of feelings is completely different from the nature of physical events. A physical event happens in spacetime and is accessible 'from the outside' through our physical senses and instruments. This produces a so-called third-person experience shared by all observers.
