Historian William Bouwsma once noted that the past is not the "private preserve of professional historians." Rather, he argued that history is a public utility, like water and electricity. If Bouwsma is right, the kind of history most people want is like water: clear, available at the turn of a knob, and easily controllable. But really, history is more like electricity shooting down the string of Franklin's fabled kite: wild, with alternating currents and unexpected twists, offshoots, and end results.
