Beyond Zero and One (Andrew Smart) / quote 110 of 171
Hallucination as an unchecked model
Visual awareness is not simply a translation of what our eyes see. Our subjective reality is an internal model that our brain must check against the input coming from our eyes. Hallucinations result when our brain does not check the model thoroughly, or rather when the brain cannot check the model it has created because of disease, exhaustion, lack of oxygen, or drugs.
