I often write op-eds that seek to warn or reassure an audience that contemporary challenges have antecedents in the past, and do so by drawing on historical, literary, and cultural allusions.
But I am not a mere political "combatant" trafficking in "impressions," but an academic historian who has written a number of scholarly books and comprehensive studies of the ancient and modern world, from the Peloponnesian War and the rise of the Greek city-state to the nature and origins of war, and, most recently, World War II.
Data is essential to all those histories that draw on literary, epigraphical, archaeological, and historical footnoted sources, many of them untranslated and accessible only in ancient and modern foreign languages.
"Data" is not always the province of some abstract discipline that is, in turn, proof of disinterested scientific inquiry. We should know this from the past abuse of "data-driven" research to substantiate pseudo-sciences like phrenology, astrology, and scientific racism, all of which variously claimed that their analytics were unimpeachable.
Numerical quantification does not necessarily trump the use of historical allusion, common sense, or contemporary custom and practice. Instead "data" is an often inexact tool. And it is subject to a similar range of errors, wrong methodologies, hubris, and partisanship that the historian deals with in analyzing evidence from the past.
Especially worrisome is the recent habit of social scientists and statisticians of claiming near-scientific authority through purported numerical precision.
This is certainly not warranted by the wide variances in the manner that questions are asked; in the size and accuracy of samples taken; and in the problematic habit of comparing how those in the past answered the same questions posed in the present --- as if culture is static and does not affect attitudes and protocols that warp responses across time and space in ways that we are not quite sure about.
A minor recent example of faux statistical exactitude: on the Tuesday morning of the 2016 Election Day, we were assured by The New York Times that Donald J. Trump had either a 15 percent, 8 percent, 2 percent or less than 1 percent chance of winning the election, based on the Times's tracking and aggregation of various scientific models and polls. The supposed master of electoral analytics, Nate Silver, was criticized as too pessimistic by many Clinton supporters for stating that Trump had on Election Day a 29 percent chance of winning the Electoral College.
Such precise percentages stamped inexact methodologies with a precision they certainly did not deserveand yet it was likely intended to do so to instill public confidence in such purportedly irrefutable "science," and in those who deploy it.
I commute weekly to Stanford from my rural home in one of the poorest areas of the state in southwestern Fresno County, about 2 miles from a Walmart that I in fact visit biweekly. But what I see there, and in adjoining parking lots, quite candidly sometimes does worry me --- although not as much as the recent Nortenos gang shoot-out across the street in which my 65-year-old twin brother and neighbor was nearly caught in the crossfire, or the corpse which my wife and I discovered two years ago in our orchard.
So I try to aggregate historical examples, contemporary news, data, and personal anecdote by visiting and talking to all sorts of Americans from all walks of life.
Most people get their "news" from somewhere, most likely through absorption from popular culture. If recent polls accurately suggest sharply divided and incompatible views over the Kavanaugh hearing, that does not mean responders are without some sort of access to such information.
The vast majority likely aggregate news of the hearings not by watching it or listening to it or reading about it. They instead soak it up through anecdote, second- and third-hand telling, conversations with friends and coworkers, and bits and pieces on the car radio and 30-second updates on TV between entertainment and sports fare.
Yet those fragments and abbreviations of information ultimately are predicated on, and find their fonts in, polarized cable and network coverage, the Internet and social media, and radio, where there is a new zealotry and advocacy that reflects radical cultural and technological changes, ranging from the rise of the Internet, social media, 24/7 cable news, and upheavals brought about by everything from globalization to changing social mores and massive illegal immigration.
It is now difficult not to witness political sermonizing in popular culture in a fashion not seen in the recent past. The Oscars, Grammys, Hollywood movies, stand-up comedy, and professional sports were never devoid of politics, but they were not perceived as all-political.
Such current ideological saturation of entertainment might explain why many of these venues are suffering losses in audiences, of which political weariness may be one contributing cause, and polarization and anger another.
Historians often cite the 1856 caning in the Senate chamber of northerner Sen. Charles Sumner by South Carolinian Representative Preston Brooks -- roughly five years before the outbreak of conflict at Fort Sumter -- as an iconic warning that previous heated rhetorical differences would increasingly likely be resolved only through violence.
In our own era, there was a "Brooks moment" when Bernie Sanders-partisan James Hodkinson tried to take out a cadre of 24 Republican congressional representatives at an Alexandria, Virginia, baseball game, a shooting that resulted in the near-death of Republican Majority Whip Steve Scalise.
Physical confrontations such as the recent cornering of Sen. Jeff Flake in a Senate Elevator or California Representative Maxine Waters's call ("If you see anybody from that cabinet in a restaurant, in a department store, at a gasoline station, you get out and you create a crowd, and you push back on them, and you tell them they're not welcome anymore, anywhere.") have had real consequences. I do not recall guards ever being needed before, as they sometimes now are after the Kavanaugh hearing, to escort senators to congressional hearings.
In the last decade-and-a-half, we have seen the growth of a new genre of presidential assassination chic, voiced in mainstream venues such as novels (e.g., Nicholson Baker's 2004 Checkpoint), films (the 2006 "docudrama," Death of a President), and newspapers (in Charlie Brooker's 2004 Guardian piece) that imagine, or even hope for, the assassination of a sitting president. These are not isolated incidents of wackiness. Google "Johnny Depp and President". . .
Today's university campuses would likely not tolerate a free-speech area analogous to what was originally conceived by Mario Savio at Berkeley in 1964, in which anyone could express unpopular opinions.
Scientists fear to express openly their skepticism about man-caused global warming and its government remedies, or socially constructed gender orientations, without real fears of career damage.
The recent Kavanaugh hearings reflect that some of the nation's most powerful elites do not really believe that traditional constitutional norms of due process, or at least its spirit that emanates from the courtroomvigorous cross examination, the right of the accused to be presumed innocent, adjudication of doubt by witnesses, testimonies, and physical evidence, the inadmissibility of hearsay, and the idea of a statute of limitationsshould apply in the matter of alleged sexual harassment.
So, we do not always need reliance on data to sense recent polarizing developments have worrisome precedents. Nearly 500 American cities or jurisdictions have declared themselves entirely exempt from the full enforcement of U.S. immigration law.
The obvious parallels are the states-rights efforts in the turbulent 1960s to nullify federal integration edicts, or perhaps even the antebellum nullification crises.
Statistics do report that in actual numbers and percentages, America is currently experiencing a near-record number of immigrants, both in quantum (ca. 60 million) and percentages (14.7 percent). I agree wholeheartedly with Fiorina that the engine of the melting pot, while damned in the abstract, still works in the concrete.
And I can attest that Americanization (a now near-pejorative word) continues both in my own racially mixed extended family, and from what I witnessed in 21 years of teaching classics to mostly immigrant and first-generation American students.
But the numbers of arrivals is now so high, and those who now come without legal sanction so numerous, that there is increasingly less margin of error when assimilation, integration, and intermarriage are so often (by our own institutions) considered passÃ©, at least in comparison to the attractions and career enhancements of the salad bowl and identity politics.
To conclude with some "data." In a December 2017 Pew Research Center poll, an "overwhelming majority (86%) of Americans" stated that conflicts between Democrats and Republicans "are either strong or very strong," much more so than over traditional divides of race or class.
The point is not to suggest that the Pew poll is necessarily accurate or proves that worse is to come; it is only to warn that, increasingly, Americans may see their contrasting agendas with a new degree of passion and less confidence in the possibilities of compromise.
More recently, Michigan State professor Zachary Neal's data suggested that political parties had become the most estranged and polarized in modern history: "What I've found is that polarization has been steadily getting worse since the early 1970s. Today, we've hit the ceiling on polarization. At these levels, it will be difficult to make any progress on social or economic policies."
Popular culture can certainly provide a much-needed veneer of commonality in language, fashion, and habit.
But without a commitment to shared values, a common agreement on constitutional norms, allegiance to the rule of law, and some deference to collective American traditions and customs, factions that superficially seem similar in their language and habits might devolve into violence of the sort now associated with Antifa or attacks on invited speakers to college campuses (or even on congressional representatives).
The lesson from the American Civil War and the French Revolution, the rise of Nazism in Germany or of Bolshevism in Russia, is not that clear majorities of partisans and countless news junkies are needed to foment extremism and tear apart a country.
Instead, it is that zealous and sometimes warring tiny minorities can escalate tensions, nullify opposition, and bully the silenced majority to sanction--or at least not object to--the violence by which they eventually make their illiberal agendas go mainstream.
