One of the greatest of joys known to man is to take such a flight into ignorance in search of knowledge. The great pleasure of ignorance is, after all, the pleasure of asking questions. The man who has lost this pleasure or exchanged it for the pleasure of dogma, which is the pleasure of answering, is already beginning to stiffen.

Robert Lynd (1892-1970) American sociologist [Robert Slaughton Lynd]
