> The eyes and visual system works but they have no conscious experience of it. Why? No one knows There's some parallels with epilepsy patients that have split brain surgery, essentially isolating both hemispheres. I can't remember the precise details, but in one experiment, the left (language) side of the brain is able to post-hoc rationalize picking up a glass of water, after the right side of the brain was asked to do so (presumably in the left ear). When asked in the right ear, "Why did you pick up the glass", the left brain simply replies to the researcher that they wanted to pick up the glass. This experiment implies 'dual consciousness', but why stop at two? But certainly dual consciousness could also explain blindsightedness. https://en.wikipedia.org/wiki/Dual_consciousness https://en.wikipedia.org/wiki/Dual_consciousness
