"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."
? R. D. Laing
