It would be a mistake to believe that the current decline in historical literacy is due to the loss of some homogeneous version of the American story that used to hold the nation together. The problem is rather that younger generations are no longer being exposed to the historical themes that would most attract their interest.
Wilfred McClay’s new textbook on American history outshines the competition, thanks to its balanced approach, its superb narrative style, and its reintroduction of topics and themes that have long since fallen from the pages of most classroom editions.
You do not need a license to practice history. Instead, all you need to do is work hard, do research, go to the sources, make the past meaningful, and write in a way that attracts readers.
