I will now pose the Screen Argument as a question:
Where in the physical world does the image you observe when you look at things exist?
Think about it.
Where in the physical world does the image you are looking at right now exist?
First off, its not right in front of you. If it were anywhere in the physical world, it would be in your brain. The brain is what interprets the information sent to it by the eyes.
But is the image in the brain?
In a sense yes, in a sense no.
On the yes side, there are reactions going on in the brain that correspond to what you see in a 1 to 1 fashion.
On the no side, consider this: The image you see when you look at a tree contains the color green (if the leaves are green). If we dissect a brain, we don't find the color green. We don't find a picture of a leaf. We don't find a picture of a tree.
So, what is going on in your brain corresponds to, but IS NOT EQUAL to the image you observe day to day.
That image that you see day to day exists, though. There it is, isn't it? In fact, your visual experience of the physical world is tied to and dependent on that image. It is how you are reading this sentence right now.
But this sentence does not exist (in the form that you are reading it) in your brain. But it exists. But it doesn't exist in the physical world.
Therefore, the image you experience as you read this sentence does not exist in the physical world.
The same holds true for your senses of hearing, touch, and taste. I think a similar argument can be made based on your experience of thoughts and memories.
Conclusion: The image you experience of this sentence does not exist in the physical world (although it corresponds to activity in your brain).
