@9toenails "I mentioned private language and analytic/synthetic really just to warn any neophytes not to take the author's views as exactly characterising conventional wisdom thereon. His conclusions pretty much stand independently of determinations of any controversial issues in either area.
If you want to know more, Stanford Encyclopedia gives good coverage: private language; analytic-synthetic. Bibliographies there are useful, in particular.
That is more reading than many might wish for. And perhaps I should offer a little more than references. Here is something some may find useful/interesting, and which iirc does not make it into the main Stanford piece (although it is covered in some of the references in the biblio). I think it might help make the point here.
As well as what we might call the 'standard' private language argument (from Wittgenstein's Philosophical Investigations ), Wittgenstein offers another argument which might also be called by the same name. Norman Malcolm describes this as an 'external', as opposed to 'internal', 'attack on private language'. (See Malcolm 1954 ‘Wittgenstein’s Philosophical Investigations’, The Philosophical Review, 63 .) (I have seen this described as the 'conceptual' private language argument.)
Here is Malcolm's (genuinely succinct, and I think clear as well as exegetically correct) characterisation of this (Wittgenstein's) external argument:
" ... If I were to learn what pain is from perceiving my own pain then I should, necessarily, have learned that pain is something that exists only when I feel pain. For the pain that serves as my paradigm of pain (i.e., my own) has the property of existing only when I feel it. That property is essential, not accidental; it is nonsense to suppose that the pain I feel could exist when I did not feel it. So if I obtain my conception of pain from pain that I experience, then it will be part of my conception of pain that I am the only being that can experience it. For me it will be a contradiction to speak of another's pain. This strict solipsism is the necessary outcome of the notion of private language." ( op. cit. P.538)
This is about (the concept of) pain. The conclusion is that I cannot (on pain of being condemned to a very strict form of solipsism) learn what pain is from perceiving my own pain. Does the argument go through similarly with the concept of gender (construed as some kind of feeling of being a certain way)?
Malcolm considers a possible response: what if I simply say, 'If I talk of someone else's gender [pain], I am talking of her having the same as me when I talk of me having my gender'? ... "But if I suppose that someone has a pain, then I am simply supposing that he has just the same as I have so often had" (see Philosophical Investigations 350 ).
Here Malcolm continues,
'I will quote Wittgenstein's brilliant counterstroke in full:
"That gets us no further. It is as if I were to say: "You surely know what 'It is 5 o'clock here' means; so you also know what 'It's 5 o'clock on the sun' means. It means simply that it is just the same time there as it is here when it is 5 o'clock."-- The explanation by means of identity does not work here. For I know well enough that one can call 5 o'clock here and 5 o'clock there " the same time," but what I do not know is in what cases one is to speak of its being the same time here and there.
"In exactly the same way it is no explanation to say: the supposition that he has a pain is simply the supposition that he has the same as I. For that part of the grammar is quite clear to me: that is, that one will say that the stove has the same experience as I, if one says: it is in pain and I am in pain." ( ibid ) '
Again, try replacing 'pain' with 'gender' (as a kind of feeling or perception of one's identity). Does that help? Interesting, anyway, I hope."

This is interesting and I wonder is psychology has bridged this seeming gap with the discovery of structures like mirror neurons?
These are a class of neuron that modulate their activity both when an individual executes a specific motor act and when they observe the same or similar act performed by another individual. And their influence extends beyond simple motor actions - eg when a person cries and this prompts crying from a person that sees them it is considered that mirror neurons are at work. They can provide a direct internal experience of another person's actions or emotions and may be the neurological basis of empathy.
So they could provide a pathway for explanation for sharing another's pain ( & gender???). There is no contradiction to speak of another's pain with these mechanisms, and you can learn about the more general feeling of pain from experiencing it yourself.
