Incorrect - though for some, it seems to be their only access to productive creativity. What about collaborative creativity? What about spontaneous creativity which is independent of environment? What about the kind of creativity that happens when a person goes into a very public place and sits alone and writes poetry... is that solitude? I know some writers who are exactly as described in the interview. They cannot work if they are not alone. It makes sense. I know others who are almost the opposite - who need the presence of humanity to be creatively productive. Methinks the calculus here is more complex than Rilke states.
