You're muddling it up too much. Not only is this not complicated enough to require sophisticated logic, but your reasoning doesn't even make sense.
If I say I recognize stage 5, then there is a chance that I do not recognize what it is that I do not recognize.
Meta-awareness has nothing to do with this. If you're aware of stage n then all you can be unaware of are stages above it, and whether you're aware that you're unaware of them is unimportant.
Goddammit. Do you see what meta does to language? Why did you have to drag it in here?
I say I recognize stage 5, but because I am not at stage 7, I can't recognize stage 5
So you're not certain that you're at stage 5 but you're certain that you're not at stage 7, even though you have evidence to support the former but not the latter?
I was just joking with how the whole thing was worded. xD Just because it's a: if A is true it implys that B is true, sort of situation, so if you can prove A then you prove B. Kind of how Andrew Wiles solved Fermat's last theorem. :B
