Henry Chinaski: Ah, the eternal question... who am I?... the eternal answer... I don't know.
(From the movie "Barfly")
I just saw the movie and thought this particular dialogue was brilliant.
The first answer that comes to our mind when asked who we are is our name. But our name is no container of our being, it is only a word. Putting a name to something does not mean understanding it. As Shakespeare wrote in Romeo and Juliet,
"What's in a name? that which we call a rose
By any other name would smell as sweet;"
