In the late winter of 1815, Thomas Jefferson sat down in his study at Monticello to work out a math problem.
Under Virginia law, a person with a black ancestor had to have at least seven-eighths white ancestry to count as a fully legal citizen. Jefferson was trying to figure out how many generations it would take — and whether his children with Sally Hemings, his mixed-race slave, would make the cut. He decided they did.
That absurd calculation — by the same man who justified his nation's independence on the basis that "all men are created equal" — is one of many ironies Jill Lepore notes on her absorbing journey through U.S. history in "These Truths," a title taken from a Jeffersonian clause in that same declaration.
Lepore, a Harvard University history professor known for her lucid New Yorker essays on American life and culture, dives into the cross-grained American epic starting with Christopher Columbus in 1492 and ending with Donald Trump in 2016.
That story, she writes, essentially is the working out of a question that the founders raised in the 1700s and every generation since has struggled to answer: Can a people rule themselves "by reflection and election, by reason and truth, rather than by accident and violence, by prejudice and deceit?"
Lepore's history shows the answer is yes, they can — but be prepared for some backsliding. If the current national divisiveness is troubling, it's not unprecedented. Slavery, civil war, Jim Crow, depression, blacklists, undeclared wars: It's been a bumpy ride.
In the past few decades, thick American surveys have hit the shelves ranging from Howard Zinn's 1980 radical history to Paul Johnson's buoyant, libertarian 1997 volume. Lepore's book is neither as glibly optimistic nor as comprehensive as Johnson's; if you're looking to find out about the Gadsden Purchase, Custer's Last Stand or the Wright Brothers, you won't find it here.
Instead, "These Truths" is primarily a political history that focuses on the expansion (and contraction) of rights in the United States — speech, religion, voting, even gun rights — along with political equality and popular sovereignty. And while Lepore pays due deference to the Mount Rushmore-sized figures who have wrestled with those ideas, her protagonists make up a more diverse crowd than those in most histories.
