A quote from Jacob Weisberg's book on Bush found on Neo Neo-con,
Richard Perle, foreign policy adviser [says]: "The first time I met Bush 43… two things became clear. One, he didn't know very much. The other was that he had the confidence to ask questions that revealed he didn't know very much.
Weisberg intended it as a slam on Bush but anyone who's depended on those who can't ask questions for fear of displaying ignorance understands the wisdom here.
