Where does the Mary argument fall short for you in that Mary finding new information out when she finally enters into the sunlight world seeing red for the first time?
Because she will see red just like a camera would, given that red is a quality and her brain the instrument observing it. red is observed or is in the object [transparent photons].
Do you think a camera would be able to experience a quale (the color red) in the same regard as a human being does?
I think it digitally or chemically copies the color red yes. Equally I think that in optical illusions, the inquirer is shown some color, but the brain inputs the color it expects to see. so when the object with the color is moved to an area which is another color, it is revealed that the object is indeed that color. This says to me that the brain composes color perhaps not unlike a camcorder can ~ the brain can do graphics. The problem with qualia then, is that you get red when it isn’t there physically in the light info.
The philosophical zombie is all of the above, what it means; that the human machine will do what cameras can do. Even with mental qualia.
I saw a documentary where a scientist made a blind man see [very blurred though] by re-routing info from his tongue [thus acting like eyes], so it appears that the brain just needs enough info to say something is e.g. red, and there will be the quality red.
- it all means that qualities [red] are a fundamental element of the real world - but are not physical.
