History provides instructive examples. "What history teaches it teaches mainly by example. It inspires courage and tolerance. It encourages a sense of humor. It is an aid to navigation in perilous times. We are living now in an era of momentous change, of huge transitions in all aspects of life--here, nationwide, worldwide--and this creates great pressures and tensions. But history shows that times of change are the times when we are most likely to learn." --David McCullough History makes us better thinkers. "It is not simply general abilities, such as memory or intelligence, nor the use of general strategies that differentiate experts from novices. Instead, experts have acquired extensive knowledge that affects what they notice and how they organize, represent, and interpret information in their environments. This, in turn, affects their abilities to remember, reason, and solve problems." --National Research Council
