We are playing a game.
The game runs like this:
the only thing you really know
is what you can put into words.
Let's suppose I love some girl, rapturously
and somebody says to me
Do you really love her?
Well, how am I going to prove this?
They'll say, Write poetry.
Tell us all how much you love her.
Then we'll believe you.
So if I'm an artist, and can put this into words,
and can convince everybody I've written the most ecstatic love letter ever written
they say All right, ok, we admit it
you really do love her.
