The American experiment rests on three ideas --- "these truths," Jefferson called them --- political equality, natural rights and the sovereignty of the people. And it rests, too, on a fearless dedication to inquiry, Jill Lepore argues, because self-government depends on it. But has the nation, and democracy itself, delivered on that promise? THESE TRUTHS tells this uniquely American story, beginning in 1492, asking whether the course of events over more than five centuries has proven the nation’s truths, or belied them. To answer that question, Lepore traces the intertwined histories of American politics, law, journalism and technology.
