" "It was only twenty-five years ago that the philosopher Joseph Levine officially dubbed it the explanatory gap, which he later described in his book Purple Haze: We have no idea, I contend, how a physical object could constitute a subject of experience, enjoying, not merely instantiating, states with all sorts of qualitative character. As I now look at my red diskette case, I’m having a visual experience that is reddish in character. Light of a particular composition is bouncing off the diskette case and stimulating my retina in a particular way. That retinal stimulation now causes further impulses down the optic nerve, eventually causing various neural events in the visual cortex. Where in all of this can we see the events that explain my having a reddish experience? There seems to be no discernible connection between the physical description and the mental one, and thus no explanation of the latter in terms of the former.2

Additional quotes by Michael S. Gazzaniga
How come the left brain doesn’t complain about the fact that it is no longer conscious of things on the left side of space? Imagine having your brain disconnected. Imagine waking up in your hospital room the next morning and, as your surgeon walks in to see how you are faring, you only see the left half of her face. Don’t you think you would notice that the right half is not there? The thing is, you would not. In fact, your left hemisphere wouldn’t even be conscious of the fact that there is a left half of space. But this is the weird part: I spoke as if the new, split version of you were just your left hemisphere, and that is not true. You are also your right hemisphere. The new “yous” have two minds with two completely separate pools of perceptual and cognitive information. It is just that only one of the minds can readily speak. The other initially cannot. Perhaps, after many years, it will be able to produce a few words.

Plainly stated, I believe consciousness is an instinct. Many organisms, not just humans, come with it, ready-made. That is what instincts are, something organisms come with. Living things have an organization that allows life and ultimately consciousness to exist, even though they are made from the same materials as the non-living natural world that surrounds them. And instincts envelop organisms from bacteria to humans. Survival, sex, resilience, and walking are commonly thought to be instincts, but so, too, are more complex capacities such as language and sociality — all are instincts. The list is long, and we humans seem to have more instincts than other creatures. Yet there is something special about the consciousness instinct. It is no ordinary instinct. In fact, it seems so extraordinary that many think only we humans can lay claim to it. Even if that’s not the case, we want to know more about it. And because we all have it, we all think we have insight into it. As we will see, it is a slippery, complex instinct situated in the universe’s most impenetrable organ, the brain.
