To EnterOrion:
I wonder about what you say here:
Our perception doesn't matter, only what we alone see.
I don't think I know what you mean by perception. To philosophers, this is the act of perceiving, typically of seeing. But this must not be how you mean it, otherwise it doesn't make sense. Maybe our worldview or something?
At any rate, you say that only what we alone see. Now, you can get out of the dreaming argument with this statement because we aren't perceiving anything. They are simply mental images. Perception requires an object of perception.
All to the better - your line of argument (I'm not sure you would say that you're arguing so much as just explaining your thoughts) seems to avoid a certain kind of skepticism, which is nice.
But what about seeing mirages, or hallucinations? Our perception is certainly a very good tool to interact with the world around us, but it certainly isn't infallible.
But in the case of a hallucination, what you're seeing isn't really there. If I hallucinate a pink rat in the corner, there is no actual object of perception.
Of course, you may be able to slip by again by saying this isn't perception because you're not seeing anything. The images are in your mind. The problem is that how do we come to know that? In dreams, illusions, and hallucinations, we at least believe that we are perceiving something. Otherwise, we wouldn't have nightmares, right? We believe, at the time, what is going on in a dream.
It is through memory, reflection, and a consistency of experience that allows us to tell good cases of perception from bad ones.
But by appealing to memory, your position is now very vulnerable to the case I first mentioned, where you have just popped into existence with memories and such. But these memories aren't based on experience - they're just planted in you. It seems like there is still an appeal here to say that the world actually is how we perceive it. But then that means that mirages are real, as well as pink rats.
I dunno, just thought I'd mention that and see what you think.
