Graham, as you acknowledge consciousness and/or the brain has no absolute/direct knowledge/observation of anything, so please therefore inform us of something which is not an illusion.
Materialists/physicalists are demonstrably guilty of associating the meaning of 'illusion' wrt popular experience/learning which have no actual bearing upon ontology/metaphysics. Guilty of irrational/incorrect conceptualization.
How you bunwits attain the confidence to hang around the philosophy forum as though you own the joint, will always be a puzzle to me.
