The greatest contradiction of common sense

On the one hand, our common sense says that the colors we see, the sounds we hear, the smells we feel, the textures we sense, are all the actual and concrete reality. We take it for granted that they are all really 'out there,' in the sense of being outside our heads. On the other hand, our common sense also seems to suggest that death is the end of our consciousness. Even if we don't acknowledge this intellectually or spiritually, most of us fear the end of consciousness with enough sincerity to betray our belief in its possibility.
Now, the point of this essay is extraordinarily simple: these two common-sense beliefs are mutually exclusive. They cannot be both true. Either everything you sense around you right now, including the computer in front of you, is a kind of "hallucination" inside your head, or your consciousness doesn’t end upon what we call physical death. And by the time we come to the end of this essay, I believe you will agree with me.
Here is a narrated, video version of this essay:
Let’s start with the postulate that bodily dissolution — death — indeed implies the end of consciousness. Such a notion is entirely based on the idea that your body, particularly your brain, generates all your experiences. After all, what other reason could we have to believe that consciousness ends if the brain stops working? But if the notion is true, then all of your subjective experiences and their qualities — colors, sounds, flavors, textures, warmth, etc. — are merely representations created within your head. The "real world out there" has none of the qualities of experience: no colors, no melody, no flavors, no warmth. Supposedly, it is a purely abstract realm of quantities akin to mathematical equations. It cannot even be visualized, for visualization always entails qualities of experience. In essence, if this is true, your entire life unfolds inside your skull. Your actual skull is somewhere beyond the room where you are sitting, enveloping it from all sides. After all, the room you are experiencing right now is supposedly within your head.
But what if all this is baloney? What if the colors, sounds, and smells you are experiencing right now are the real reality — the actual world — not "hallucinated" representations within your skull? Then the necessary implication is that all of reality is in consciousness, for reality is then "made of" the qualities of subjective experience. But if that is so, it is your body that is in consciousness, not consciousness in your body. After all, your body is in reality, not reality in your body. And then, in turn, the dissolution of your body cannot imply the end of consciousness; not any more than the death of your dreamed-up avatar in a nightly dream can imply your physical death. After all, it is the avatar that is in your dreaming consciousness, not your consciousness in the avatar. Do you see the point?
Therefore, either all reality you can ever experience is a kind of "hallucination" inside your skull, or we have absolutely no reason to believe that physical death entails the end of consciousness. It’s one thing or the other. You take your pick: which alternative is crazier? I’ve taken mine: I am unable to deny the reality of my immediate experience, which far precedes the models and abstractions of our mad materialist culture.
So let us dare entertain the possibility that reality is exactly what it seems to be: that it has qualities, not just quantities. Let us acknowledge what every civilization before Western rationalism always took for granted: that colors, smells, sounds, and flavors are really out there, not just inside our heads. How do we then explain the big questions that materialists claim to require an abstract reality fundamentally outside consciousness in order to be made sense of?
First question: "If reality is a kind of dream in consciousness, how come we seem to be all sharing the same dream?" The idea behind this question is that, because our bodies are not connected in the fabric of space-time, our personal psyches are also not connected and, therefore, cannot be sharing a dream. But this assumes that consciousness is in the body, as opposed to the body in consciousness. If our bodies are in consciousness, the fact that our bodies are separate does not imply that our psyches are also separate. Nothing in our experience prevents our psyches from being connected — unified — at the deepest, most obfuscated level, like the visible branches of a tree unite at the invisible root. That highly obfuscated, collective root level may well be the unified source of the shared dream we call consensus reality. And that there are highly-obfuscated segments of mind (so obfuscated, in fact, that depth psychology routinely uses the misnomer "unconscious" to refer to them) is an established fact in psychology.

Third question: "There are tight correlations between brain states and subjective experience. Therefore, the brain must generate consciousness." Well, there is an alternative way of seeing this that is incredibly self-evident: the brain is not the cause of consciousness, but merely the image of a process in consciousness. Take lightning: it doesn't "generate" or "cause" atmospheric electric discharge; it’s just the way atmospheric electric discharge looks. Take a whirlpool in a stream: it doesn’t "generate" water; it is simply the way water flow localization looks. There is nothing to a whirlpool but water, yet we can point at it and say: "There is a whirlpool!" Similarly, there is nothing to the brain but consciousness, yet we can point at it and say: "There is a brain!" As a whirlpool is the image of flow localization in water, so the brain is merely the image of flow localization in consciousness. As such, it is no surprise that brain states correlate with personal — that is, localized — subjective experience: one is simply the outside view of the other! Yet the brain doesn’t "generate" consciousness for exactly the same reason that a whirlpool doesn’t generate water.
Fourth question: "If I take psychoactive drugs or suffer physical trauma to my head, my subjective experience will change. Therefore, the brain generates consciousness." The rationale here is the following: pills and trauma are assumed to exist as physical things outside consciousness. Then, because they can clearly alter your subjective experiences through physically interfering with the brain — which is also assumed to exist outside consciousness — then, the argument goes, consciousness must be generated by the brain. Notice that this entire rationale simply assumes that pills, trauma, and brains exist outside consciousness, which is precisely the point in contention! You see, if all reality is in consciousness, then a pill or a well-placed knock to the head are simply the images of processes in consciousness; they are also in consciousness, not outside it. Where else could they be? What is a pill but what you see, touch, feel in your fingers? It has color, taste, texture. It's a set of subjective perceptions with the qualities of experience. As far as you or anyone else can ever know for sure, a pill is in consciousness. Therefore, that a pill or physical trauma to the head alter one’s state of consciousness is no more surprising than the fact that your thoughts can change your emotions. Thoughts and emotions are both in consciousness, and we are perfectly comfortable with the fact that they can influence one another. For that exact same reason, we should be perfectly comfortable with the fact that drugs and physical trauma also influence our subjective states. As there is nothing to the brain but consciousness, so there is nothing to a pill and physical action but consciousness.
All questions that lead materialists to naively insist on the existence of an unprovable, abstract universe outside consciousness can be logically and empirically made sense of under the rigorous and parsimonious view that all reality is a phenomenon of consciousness, in consciousness, as I explain in my book Why Materialism Is Baloney. Your intuition that the world you experience around you right now, with all its colors, sounds, smells, and textures, is the actual reality — as opposed to a kind of hallucinated reproduction inside your head — is entirely correct. The implication of that, however, is that your consciousness — your subjective feeling of being — will not cease to exist upon your physical death. This is an inescapable conclusion derived from logic, clear thinking, and empirical honesty, not mere wishful thinking. It so happens to also be a hopeful conclusion.
