There is something I don't know
that I'm supposed to know.
I don't know what it is I don't know,
and yet I'm supposed to know,
and I feel stupid
if I seem both to not know it
and not know what it is I don't know.
Therefore I pretend to know it.
This is nerve-racking
since I don't know what I must pretend to know.
Therefore I pretend to know everything.

Are you getting impudent again? How can you be so impudent? I'm coming! I'll show you! You don't whore for me. You mustn't be smart either; you're an impudent, lousy fellow, such an impudent, lousy fellow I've never met with. Is he beginning again? You understand nothing at all, nothing at all; nothing at all does he understand. If you follow now, he won't follow, will not follow. Are you getting still more impudent? Are you getting impudent still more? How they attend, they do attend,' and so on. At the end, he scolds in quite inarticulate sounds.

A most curious phenomenon of the personality, [...] is that in which the individual seems to be the vehicle of a personality that is not his own. Someone else's personality seems to 'possess' him and to be finding expression through his words and actions, whereas the individual's own personality is temporarily 'lost' or 'gone'. This phenomenon is one of the most important in occasioning disruption in the sense of one's own identity when it occurs unwanted and compulsively. [...] The way in which the individual's self and personality is profoundly modified even to the point of threatened loss of his or her own identity and sense of reality by engulfment by such an alien sub-identity [Ontological insecurity].
