One problem with referring to anything as 'mental' is that what we call the mind and mental things and events are misleading metaphysical fictions. What and where are the mind and mental things and events?
It's a subset of brain states. So the where is the brain/in persons' heads.
What can it mean to say I know I have a pain, a thought or a sensation?
Your brain is in a particular state. That brain state has unique properties from the spatio-temporal point of reference of being the brain in question.
This isn't something unique to brains, by the way. All existents have different properties from different spatio-temporal points of reference.
What is the self that experiences these things? What is the consciousness to which a nervous system 'presents' sensations?
Again, simply a set of brain states.
Another problem is the in-built solipsism of such talk. In what way are we shut in a private world?
You're not "shut in" a private world. It's just that there are unique properties to brain states from the spatio-temporal point of reference of being the brain in question. The world isn't limited to that spatio-temporal point of reference though, of course.
The ways we talk about ourselves are all public,
Talk is public, but what we talk
about isn't always public. Typically we talk about a lot of private things, too.
because language is a social phenomenon.
Parts of language are, sure. Not all of it is. Meaning isn't social (that is, it doesn't occur, it isn't located socially. This is not saying that it's not often in response to social things. "X is in response to Y" is different than "X is identical to Y.")
I think your argument about what and where meaning 'goes on' is evidence for the conceptual confusion I'm talking about.
Everything has a location on my view, even if it's a complex location.
Do we think other primates and mammals are cut off from each other and their environments in private worlds? And if not, why not?
I don't know why anyone would think of it as a "cutting off from." It seems like you're thinking in terms of a false dichotomy where either everything is accessible and the same from everywhere (in which case why was it so difficult for us to get to the moon?) or people are cut off from each other where they can't access anything public.
