talking about Mona Hatoum's video installation "Corps étranger" it is said that:

"In exposing to her own objective stance and to the viewer the substance of which she is a part, both intimate body and foreign object, she invites an identification between artist and viewer – we all possess bodies and brains about which we feel a squeamish mixture of intellectual curiosity and felt possessiveness – and that boundary is blurred too."

1. What do "objective stance" and "both intimate body and foreign object" mean here?
2. Does "to invite an identification between" mean "to distinguish"?
3. To which "boundary" the last sentence is referring? the boundary between artist and viewer?

Answer

"to invite an identification between"  is incorrect.

Answer

the boundary between body and mind is what is meant.  The entire paragraph is a bit confusing to me because words are used incorrectly and phrased oddly.

Answer

I am not familiar with this video, but the text you wrote sounds like it was not written by a native English speaker, and has some errors.

Answer

objective stance means a fair assessment ( not having prejudice and using only the facts) 
both intimate body and foreign object isn't something we would say
