This is not a work of historical scholarship. The book’s contribution to the debate, if any, is in its ideas and argument. Thus the endnotes are mostly meant to identify a striking piece of information, or provide the reference for an unusual quote. The rule of thumb I used was, if I thought a general reader might wonder, “Where did that come from?” I’ve provided the answer. If I have relied on a secondary source for general insights I have usually mentioned it in the text, but I may have also cited it here.
