Just Your Perception, Man.
Recently reading Chalmer's Character of Consciousness I was struck by one of those enigmas that sends question marks rising to the furthest reaches of outer space--those enigmas of purely philosophical discourse
that are brought up so quickly that its assumptions are blinked over. The notion is that one could see an X that is, in reality, an o.
Reality here will mean the world as it is in-itself, independent of our practices of accessing it.
I see an X; is it really an X or simply my perception of an X that is really an O?
The best way to do this would be to examine the grounds or conditions necessary for saying that X is perceived and is not real (or not a part of reality as it is in-itself). If no conditions can be found, then one does not merely perceive, but accesses the world directly.
1. An 'X' is not really an X when there is an independent reality behind that 'X' that has nothing to with 'X'. Let me make a picture using my keyboard where < represents the perspective of a person, such as with his or her sight:
See all of that junk after the 'X'? That's the chaotic objective world that we can never know and that does not cause X (in this particular model). But wait, what is also in that picture? Isn't it the X itself?
What else could it possibly be? Were it anything else, it would be placed in front of the X relative to the individual's perspective, and the individual would no longer see an X, but would see what's in front of it, and we would be interrogating the reality of that entity instead. It should be obvious from this illustration that the X is not any less a part of 'objective' reality than all of the stuff behind it that is hidden from perception. They are all equally a part of reality as it is in-itself, but the perspective merely lacks the ability to see through the X and to the rest of the junk behind it. This can be looked at coherently in any mixture of the following two ways: the X is hiding the rest of reality but is not any less a part of that reality, or the perspective is not wide enough or does not have the conditions necessary to see the rest of reality.
2. An 'X' is not really an X when there is an independent reality behind that 'X' that, in part, causes 'X'. Another keyboard drawing, only this time include '<--' to mean 'causes' where 'X<--o' means 'o causes X':
Here, we clearly see o causing X. Of course, the individual only sees the X and not the o that is causing it. Does this place the X outside of reality as it is in itself? If I put the Jack of Hearts in my hand and hold it up to your face so that you cannot see my hand, does that remove the Jack of Hearts from the world just because my hand is what caused it to be in front of your face? No. In the same way, just because there is a hidden causal element behind the X does not remove the X from reality as it is in-itself.
3. This is not very necessary for the purposes of my argument, but another common view-point should at least be addressed--all of 'objective' reality causally interacts with one another which then causes your percepion of X:
The implications are the same as 2, except that behind my hand that holds up the Jack of Hearts there is also an arm and that that arm also covers up a body and eanything else that causes the card to be placed in your vision.
Conclusions: The world as we experience it is the world as it is in-itself, even if it is a limited view of that world.
Other Conclusions: Representationalism places an arbitrary distinction between the representation and what is represented. It should be clear that, at the very least, making the world in-itself as a represented virtual-reality construct in a person's mind does not help in the philosophical investigations about drawing the line between the 'who' and the 'what.'
