History is neither a political fable in which all the brothers are valiant and all the sisters virtuous, nor is it a tabloid expose, full of crimes and follies, signifying nothing but victimization. There is, I must admit, a caustic delight in unveiling the frailties of our Jeffersons and our Lincolns, but the delight turns malevolent when it serves only to strip the American past of anything remarkable or exceptional, or when it demeans or discourages civic engagement and confidence.
