I'm loving this quote from a blog entry at The Creativity Post:
Dumb questions are not accusatory or argumentative statements in disguise. Nor are they formulated with preconceived answers in mind. Rather, they are probing yet open. Used effectively, dumb questions lead to a deeper sense of reality, truth or purpose. They expand our capacity to see more clearly and inspire us to explore possibilities we would otherwise ignore. Above all they are interesting enough to encourage finding an answer.....
Creative questioning is not an easy discipline to master.
