The uncertainty of the observer has nothing to do with the absoluteness of reality.
No, but it has everything to do with whether the observer can say for certain whether 'absolute reality' exists or not.
And since we agree that we are all observers, then we agree that we cannot, any of us, say that 'absolute reality' exists without being somewhat uncertain; i.e., our conclusion that reality exists cannot be an absolute certain conclusion.
I would also say that it is irrational to maintain doubts about some things. For example, you have children don't you? Do you doubt that you have children? Do you doubt that you love them?
What is rational and what is absolutely, certainly, verifiably true are two different things.
Things are either real or they are not.
Of course. But we cannot know for certain whether they are 'absolutely real'.
If the moon is real then it is absolutely real.
How so? When we say something is 'real', we mean we have examined it with our fallible senses and declared the evidence 'good enough' to conclude, without complete certainty, that the thing we have examined is probably 'real'. But this is not the same as the thing itself being 'absolutely real', existing, beyond any doubt whatsoever, completely outside of our minds in some space we might call 'absolute reality'.
How can it possibly be rational to harbour doubts about the reality of the moon?
We don't harbor doubts about the reality of the moon. We harbor doubts, however small, about the '
absolute reality' of the moon.
When a woman gives birth to a child was she just pregnant or was she absolutely pregnant?
She was 'pregnant'. Why do we have to say that she was 'absolutely pregnant'? In our world and experience, simply saying she was 'pregnant' is good enough; we don't possess the complete certainty to say that she was 'absolutely pregnant'; and since it doesn't really matter if she was 'pregnant' or 'absolutely pregnant', there's really no need to bother with debating the absoluteness of her pregnancy.
If we were to debate it, though, we'd have to come to the conclusion that we cannot be certain she was 'absolutely pregnant' even if we can comfortably say she was 'pregnant'.
