Obviously, sanity is a social construct - as in - the divider of sane people from the lunatics is created socially and is dependent on statistical opinion and the consensuses of what is real and\or possible. We all have these, one needs only a few days in front of the tv to absorb all of it.
Sanity was constructed in order to put it in a social contract. Since we know the insane are sent away to pure themselves, or just stay away - It is plausible to assume that if you are free to hang around, go to work, and pay your taxes, your mental state and conditioning are most probably acceptable by the people around you. Thus, you are sane.
I'll leave the paranoid thoughts of a self-conscience pseudo-existentially questioning the identity of itself, to those who blindly believe that human broken-by-definition language could possibly reach its improvised rusted phone-lines to a matter we all daily rediscover that we have no stable idea about the nature of, that we will probably never understand how we work.
Only those who believe in an object or an abstract thingy just because there is a word for it could possibly give any meaning to sanity outside of the context of social acceptance.
We try to desperately defy ourselves, to get rid of the mystery, the unknown, the uncertain, to function as a rational, calm, peaceful, human beings. Yet we are surrounded by words like I, myself, self, soul, conscience, concentration, sanity, attention, existence, inner world, thoughts, etc.. What does each point at?

"Much madness is divinest sense to the discerning eye,
to the discerning eye much sense, starkest madness,
tis the majority
in this as all prevail,
assent and you are sane,
and you're straight way dangerous,
and handled with a chain."
No one can know if they are sane or insane, others can only assume.
