GP is saying that there are hunches that are not ready for primetime but which are creative thought nonetheless, and which need to be worked with before they can become workable. It's a good thought, echoed by quotes from other designers like Alden Dow, as well as theologians, scientists, and engineers. Not an encouraging way of letting GP know you encountered difficulty in engaging the nonstandard phrasing. GP was trying to discuss the phenomenon without disclosing his or her hypothesis directly.
