So the paradox*.
There is no I.
All there is is I.
As the I which is not is when we erroneously use the word I for me, my, mine (which are ideas relating to the false split of subject/object).
Try saying “Me is going to the shops to buy something for me.” it is grammatically false but factually true. I is never going shopping and never shall.
*(Which is only brought about by language inadequacy and not a big mystery at all.)
