Poetry is not a turning loose of emotion, but an escape from emotion; it is not an expression of personality, but an escape from personality. [...] But of course, only those who have personality and emotions know what it means to want to escape from these things. [...] What happens [to the poet] is a continual surrender of himself as he is at the moment to something more valuable. The progress of an artist is a continual self-sacrifice, a continual extinction of personality.
