"Secrecy is as indispensable to human beings as fire, and as greatly feared. Both enhance and protect life, yet both can stifle, lay waste, spread out of all control. Both may be used to guard intimacy or to invade it, to nurture or to consume. And each can be turned against itself; barriers of secrecy are set up to guard against secret plots and surreptitious prying, just as fire is used to fight fire." (p.268a)
