When you have traffic with no traffic policeman, you have gridlock. An education should provide the traffic as well as a way to guide it. A multiple-choice test lists choices A-B-C-D-E. But there's sometimes another category - "OTHER". Civilization consists, in part of being able to respond, "OTHER". You have to know about the range of choices, available to you; you have to know the limitation of those choices; and you have to be able to reject all, and seek a new solution.
