Without other people...

"All writers are ecstatics, which is why we can be seduced by the siren calls of addiction or extremism. Sartre said that there are three kinds of writers: writers who write for God, writers who write for themselves, and writers who write for other people. I write for other people. The play doesn't reside in heaven, or in a library. As a dramatist, that's your instinct: without other people, the play doesn't exist."
