Harvey Mansfield Matthew Cook
Ipswich, Mass.
The nation turns 250 next weekend, and Harvey Mansfield has been alive—and most certainly kicking—for more than three-eighths of that time. At 94, he’s America’s oldest living political philosopher after Noam Chomsky, who is three years his senior. “It all depends on how you define philosophy,” Mr. Mansfield says with a twinkle, assuring me this isn’t a dig at the self-described libertarian socialist Mr. Chomsky.
Mr. Mansfield is the nation’s oldest conservative philosopher, and he says the semiquincentennial has led to “a surge in demand” for his attention. The day after we meet, he’s due to fly to Washington to decant his thoughts on the state of the nation at a couple of think tanks. He was at an academic conference in Paris the week before. It’s all part of what he calls his “late-stage productivity,” which includes two new books published in the past six months: “The Rise and Fall of Rational Control” is a history of modern political philosophy; “Where Harvard Went Wrong” is a compendium of “50 years of commentary that fell on deaf ears.” In 2023 Mr. Mansfield retired as professor of government at Harvard, where he had taught since 1962. He was the “last conservative standing” in his department.
Mr. Mansfield sees in America a “paradox”: The U.S. is both a young, brash nation and the world’s oldest continuous democracy. “We’re a country that needs to renew itself every four years, or find out who should run it,” he says. “It has, within itself, a youth and a maturity. We change our president, which means the entire government, more or less.”
America is “an exemplar of something important, which is a successful republic. But it needs to be continually refreshed, as Machiavelli said all regimes need to be.” Mr. Mansfield says America is “exceptional because it accepts the truth of that claim.” We always itch to “go back to our beginnings and see what it was that first made us excited and fresh, and made us seek to be an example to the world.”
That can become “a form of bullying,” in which Americans “demand that other peoples do what we advise. And what we advise may not necessarily be for their good, but mainly for ours.” By the same token, “great claims are imputed to us by others, and our failure to live up to them is taken as corruption.”
One of America’s strengths is its connection with the past. The founding, Mr. Mansfield says, is “based on the critique of all previous republics.” Regimes hardly ever achieve this sort of “retrospection”: “Usually, a new regime spends its time, and wastes its resources, on proving that it is better than the regime it just succeeded.” Much better to do what America did in 1776—“look at previous republics and see what went wrong. And when you do this, you take the advice of philosophers who inspired your regime, in our case Locke and Montesquieu.” Their 17th- and 18th-century liberalism still inspires us in the 21st century.
Renovation lies at the heart of America’s history and politics. Machiavelli, Mr. Mansfield’s spiritual idol, said that all successful politics is youthful. “The young are better than the old because they don’t make presumptions,” Mr. Mansfield says. “They are willing to start something anew.” Thomas Jefferson, principal author of the Declaration, was 33 in 1776. James Madison and Alexander Hamilton were 36 and 32, respectively, when the Constitution was written. “But they were under the watch and supervision of Franklin and Washington,” 81 and 55, Mr. Mansfield says. “We kept our young under control and they didn’t go for destructive behavior.” Madison called for the Constitution to become “venerable,” which Mr. Mansfield describes as “very un-Machiavellian.”
“The young are good because they’re revolutionary,” he says. Old regimes, by contrast, are “based on routine expectations, and these are almost always disappointed. They lose out to those who are willing to make a deal, or a New Deal, to use Trump and FDR in the same sentence.”
The revolutionary origins of America set up “the great general expectation for the nation of always getting ahead,” Mr. Mansfield says. “So it’s a bad thing if the next generation has to live at the lower condition of the preceding generation. Youth can be political and also economic.” It also ensures that we, as a nation, don’t take our history for granted: “Renewing is never perfect.”
As we pore over the Declaration, he urges us to note that it begins with the words “ ‘When in the Course of human events,’ not ‘When at the end of the late 18th century’—which is, in a way, ahistorical. It doesn’t have an arc, only the course of human events, not the course of, say, republics, or colonies, or American peoples.”
He also points to a “contradiction” embedded in the Declaration, between deism—the belief in a rational, noninterventionist Creator—and theism, the belief in God who shapes and intercedes in human affairs. Mr. Mansfield delights in the phrase “Nature’s God” in the first sentence, adding tartly that “people no longer speak of nature and very little in terms of God.” The phrase is “a way of denying that the Declaration invokes the Bible’s God, and of God as an endorser or guarantor of regularity.”
Yet at the end, the Declaration makes a sort of U-turn. “You have a sudden statement of the signers,” Mr. Mansfield says. “A people finding its own independence needs some few who are willing to stake their lives, fortunes and sacred honor to endorse it.” This is “quite different from ‘all men are created equal.’ In order to ensure that principle—equality—it seems that a certain inequality is required. And it’s now said that they’re acting under ‘divine Providence.’ ” This isn’t Nature’s God, but “one that watches you.”
Mr. Mansfield finds the Declaration a “beautiful piece of writing,” while pointing out that historians “argue about how much of the credit is owed to Jefferson.” Not a modest man, he put the authorship of the Declaration on his own epitaph. “I kind of like that,” Mr. Mansfield says. “I don’t mind giving semi-divine status to the Founders. The Constitution, as the Federalist says, deserves to be venerated, not just accepted.” He calls the Founders America’s “pantheon” and observes: “That doesn’t mean that they’re all in agreement, because the Olympic gods were not.”
Are we guilty of venerating the Founders too much? “Sure,” Mr. Mansfield says, “but more often of misinterpreting them. There are a couple of great misinterpretations, like the Dred Scott decision”—in which the U.S. Supreme Court denied citizenship to blacks. Another example is West Virginia State Board of Education v. Barnette (1943), which invalidated a law compelling public-school students to salute the flag. Mr. Mansfield says the justices “made a pretty bad decision by opening up free speech to include free expression that wasn’t speech. It means that you spend all your time looking at extreme examples of expression and forget that speech, which is communication, implies a kind of rationality and sociability.” Mr. Mansfield’s objections apply all the more strongly to Texas v. Johnson (1989), which held that burning the flag is constitutionally protected: “The celebration we give to extreme expression is damaging.”
While Americans revere the Constitution, they celebrate the Declaration with much greater fanfare. “Well, according to Lincoln that’s correct,” Mr. Mansfield says. “The Declaration is more important than the Constitution. The apple of gold is in the frame of silver.” He adds that “there’s a difference between the revolutionary fervor in the Declaration and the political prudence in the Constitution, and the former was the precondition of the latter.” The Constitution was “deliberated on in peace and in secret for two whole months in Philadelphia, away from the mob, with trusted representatives from all the different parts of the country.” The Declaration “excites us, and to get excited about something requires an enemy, the British.” The framing of the Constitution could “pretty well exclude the British from consideration.”
What would the Founders think of America today? “I think they would be pretty pleased and impressed with the things we’ve gone through, particularly the Civil War and the whole problem of slavery, which they left for us,” Mr. Mansfield says. “They would, I think, like the Republicans more than the Democrats.” The GOP is “pretty much the constitutional party. They stand up for the Constitution. The Democrats are the party of ‘progress,’ which means being sometimes in accord with the Constitution and sometimes not. And when it’s not, that means a kind of democratization of all those institutions which were meant to guard us against majority tyranny.”
What would they make of Donald Trump? Mr. Mansfield cups his chin in thought. “Well, he’s tried to take the Constitution away from the Republicans as something they really want to promote. So ‘let’s make a deal’ is often at the expense of the Constitution.” Mr. Trump sees the Constitution “as inhibiting things that he wants to do. He’s always looking for a shortcut.”
I ask for examples. “Take the universities,” says Mr. Mansfield. “What he’s doing is very unconstitutional, disrespectful of the high aims of intellectual progress. He’s trying to specify the doings of private organizations, which claim to be devoted to higher nonpartisan goals.” On the other hand, “would the universities have paid any attention to their own defects and corruptions without a kick from Trump, from a person who didn’t respect them, who maybe forces them to think a little bit harder about what an ivory tower is?” He laughs and says that at Harvard, “there are more Palestinians there than there are conservatives.”
The Founders might also have liked Mr. Trump’s approach to foreign policy. “You have to think of our situation as something like the British Empire,” he says. “There’s a world out there which is at odds with itself. There’s a great distinction between rogue regimes that want to invade other people and normal or peaceful ones that don’t. And we’re in charge of the peaceful ones.” The world “is not global. It’s divided into regimes or, as the Declaration calls them, ‘peoples.’ It isn’t enough simply to deter bad regimes, because deterrence doesn’t always work. But we need to keep the fight small and within our capacities.”
Our allies—as is the nature of allies of a stronger power—“don’t want to do anything, but rather want to take a free ride. So we have to do what Trump has done to them occasionally and maintain our alliances by threatening not to do so.”
The contest with China would intrigue the Founders. “It seems like the Chinese are correcting the mistakes of the Soviet Union. It’s alarming that a country so ambitious and so lacking in liberty and self-government should be so powerful.” But the Chinese are “held back by the difference between their founders and ours. Their founders, Mao and others, don’t say much about liberty, or elections, or self-government or free markets.” They have, however, “adopted the market temporarily but successfully. They’ve grown rich and strong, in that sense, but without a constitution.”
The endgame, the old sage says, will be “a kind of test—an epic test—between our Constitution and their lack of it.”
