I was curious where this stream of thought will lead you. I have a question -- how do you define thought? I ask, because in #8 you say "Can I perceive myself by not thinking of anything? Absolutely not." Now, if by "thinking" you mean all mental activity including involuntary perceptual rendering, then I agree. But if you simply mean "conscious though" that translates to language, then you can perceive yourself without thoughts. Also, who is the "active perceiver"? I think that that is the key question here.
