Nothing could be more true in the age of unlimited access and information overload.  King Solomon wrote in Ecclesiastes, “One who tears a hole in a fence invites in a snake.”  In other words, no fence is better than a broken fence, since the former demands constant vigilance while the latter allows a false sense of security.  The more we think we know, the more ignorant we actually are.
