Please stop spouting nonsense theories about the meaning of consciousness

Quote:Dennett's last book, From Bacteria to Bach and Back made this "illusion" argument by pointing out that our brains ceaselessly construct and modify and process the "raw data" from our senses into a coherent picture. The idea that our brains construct a not-completely-accurate picture of the world for us is not exactly new. Scientists have known this for decades, and philosophers for literally millennia. Any child can notice it: What we see when we open our eyes is a composite picture made by our mind using data from both of our eyes, which is why there are optical illusions and why if you block out one eye and then the other you will see things differently than with both eyes open. And, yes, this is true of everything else we experience, not just sight.
But this is a complete non-sequitur. That our conscious experience is constructed by our brain does not in any way shape or form prove that consciousness is an illusion. If I say that I'm going to see Shakespeare's Hamlet tonight, and you respond by saying, "That's not true, because Hamlet never existed," that fact would be irrelevant: I will still be sitting in a theater experiencing Shakespeare's Hamlet. The fact that our consciousness is in a large sense a "theater" is important to know, but it doesn't alter the fact that there is still "someone" watching the play.
In fact, this point could just as easily be taken as evidence for the existence of the spiritual world. Our brain ceaselessly constructs reality for us. Indeed, we only grasp reality through concepts, which are nonphysical realities. We only see a flower as red because we have a concept of the color red; there is no such thing as the color red in reality, only different wavelengths of light perceived by our nervous system and interpreted by our minds in such a way as to give us the utterly subjective experience of seeing something as red. In this sense, we have a much more intimate experience of the nonmaterial world of concepts, ideas, and the mind, than of the world of matter.
But the bottom line is this: Of course consciousness is not an illusion, since it's the only thing that we have direct, unmediated experience of...
'Historically, we may regard materialism as a system of dogma set up to combat orthodox dogma...Accordingly we find that, as ancient orthodoxies disintegrate, materialism more and more gives way to scepticism.'
