It can be seen that way. We can assume either way. We 'do not know' either way what the evidence is showing us.
Let's deal with this first.
We have:
(1) evidence of brain activity that is mental activity (I gave a link that demonstrates some MRI imaging of mental content--and by the way, we could just as well say that this is evidence of mental activity that is brain activity--that's fine, because the two are identical as far as we can tell),
and
(2) evidence of brain activity that isn't mental activity (I gave the example of autonomic control of heart rate; there's no mental correlate for that, but we can demonstrate that it's something that brains do.)
(1) is a subset of brain activity that is mental activity.
(2) is a subset of brain activity that isn't mental activity.
So the evidence shows that brain activity is mental activity, but it also shows that not all brain activity is mental activity. Brain function is broader than just mental function.
You're claiming that the same evidence somehow shows that brain activity (or at least some brain activity) is a subset of mental activity, but that mental activity is broader than brain activity, that there is some mental activity that is NOT brain activity. Where is the evidence of mental activity that is not brain activity?
Your claim makes no sense given the evidence I'm presenting. So I'm asking you to in detail explain how it's supposed to make sense.
