“It is frequently more rewarding merely to ask pertinent questions. It may get someone to go and look for an answer. If you get a silly answer, which can easily happen, you can return to the charge with even more telling effect. Whatever happens, don't give up and don't despair. Results may not be immediately apparent, but you may have touched a receptive chord without knowing it. Even the most unsympathetic and unenlightened politician, industrialist or bureaucrat begins to take notice when a lot of people write about the same subject.”
