@Fido,
That would depend on what you mean by idiot? In this sense I think it would be you that is the idiot. In this world in all of our conciousness, at the base of everything is nothing. If you don't believe me, then completely explain the philosophy of language and everything that goes along with it...and that's just a single aspect. The bases of everything was something created out of thin. We use these created tools to try and give form to our thoughts and perceptions and to convey our experiences through them. With that we can only assume that we actually know things. We think that we're going somewhere, while having no idea whether we going anywhere or where we're headed.
Ultimately I believe there are only 2 possible beliefs concerning this, but many branch off from them. Both beliefs amount to either everything exists, or only I (in a general sense) exist. There's no inbetween, something's can't exist while other don't.
I believe that only our concious perceptions of everything doesn't truly exist, but the objects themselves do. I don't believe that only I exist, for it would mean that we don't actually learn anything, but create it. If something new comes into our conciousness I believe that it existed beforehand and that I was just unaware of it. If you don't believe that then you may as well claim to be God. I don't see any other possibilities, but if there are I would love to learn of them. As stated before, anything that exists has it's own absolute truth. It's an absolute truth that you cannot deny your own existence, for if you don't exist, then you cannot make the statement to deny it because there would be nothing to generate the thought in the first place.
