Lecturer: Roger Berkowitz, Associate Professor of Political Studies and Human Rights at Bard College; Academic Director, Hannah Arendt Center for Politics and the Humanities.
In this lecture, Roger Berkowitz welcomes the incoming Class of 2014 at Bard College with an important question: “Is humanity important?” The human race has witnessed impressive scientific and technological achievements, some of the most remarkable of which have occurred in the past 50 years. While some of these have advanced the history of humanity, others threaten to dampen its spark. Nuclear and biological weapons are capable of killing untold millions of people, and the urge to embrace automation in our everyday lives cultivates the fear that society may one day embrace euthanization as a way to rid itself of “superfluous persons”. Acknowledging this increasingly dangerous world we live in, Berkowitz argues it is imperative that we at this moment in time take a closer look at ourselves and consider our significance. He proposes two sources that can help us in our task: Galileo and Google.
I was at dinner with a colleague this week—midterm week. Predictably, talk turned to the scourge of all professors: grading essays. There are few tasks in the life of a college professor less fulfilling than grading student essays. Every once in a while a really good essay jolts me to consciousness. I am elated by such encounters. To be honest, however, reading essays is for the most part stultifying. This is not the fault of the students, many of whom are brilliant and exuberant writers. I find it trying to wade through 25 essays discussing the same book, offering varying opinions and theories, while keeping my attention and interest. How many different ways can one ask for a thesis, talk about the importance of transition sentences, and correct grammar? For some time it is fun, in a way. One learns new things and is captivated by comparing how bright young minds see things. But after years, grading the essay becomes just part of the worst part of a great job.
So how might my colleagues and I react to news that EdX—the influential Harvard-MIT led consortium offering online courses—has developed software that will grade college student essays? I imagine it is sort of like how people felt when the dishwasher was invented. You mean we can cook and feast and don’t have to scrub pots and wash dishes? It promises to allow us to focus on teaching well without having to do that part of our job that we truly dread.
The appeal of computer grading is obvious and broad. Not only will many professors and teachers be freed from unwanted tedium, but also it may help our students. One advantage of computer grading is that it is nearly instantaneous. Students can hand in their work and get a grade and feedback seconds later. Too often essays are handed back days or even weeks after they are submitted. By then the students have lost interest in their paper and forgotten the inspiration that breathed life into their writing. To receive immediate feedback will allow students to see what they did wrong and how they could improve while the generative impulse underlying the paper is still fresh. Computer grading might encourage students to turn in numerous drafts of a paper; it may very well help teach students to write better, something that professorial comments delivered after a week rarely accomplish.
Another putative advantage of computer grading is its objectivity and consistency. Every professor knows that it matters when we read essays and in what order. Some essays find us awake and attentive. Others meet my eyes as they struggle to remain open. As much as I try to ignore the names on the top of the page, I can’t deny that my reading and grading is personalized to the students. I teach at a small liberal arts college where I know the students. If I read a particularly difficult sentence by a student I have come to trust, I often make a second effort. My personal attention has advantages but it is of course discriminatory. The computer will not do that, which may be seen by some as more fair. What is more, the computer doesn’t get tired or need caffeine.
Perhaps the most important advantage for administrators considering these programs is the cost savings. If computers relieve professors from the burden of grading, that means professors can teach more. It may also mean that fewer TA’s are necessary in large lecture courses, thus saving money for strapped universities. There may even be a further side benefit to these programs. If universities need fewer TA’s to grade papers, they may admit fewer graduate students to their programs, thus going some way towards alleviating the extraordinary and irresponsible over-production of young professors that is swelling the ranks of unemployable Ph.D.s.
There are, of course, real worries about computer grading of essays. My concern is not that the computers will make mistakes (so do I); or that we lack studies that show that computers can grade as well as human professors—for I doubt professors are on the whole excellent graders. The real issue is elsewhere.
According to the group “Professionals Against Machine Scoring of Student Essays in High-Stakes Assessment,” the problem with computer grading of essays is simple: Machines cannot read. Here is what the group says in a statement:
Let’s face the realities of automatic essay scoring. Computers cannot ‘read.’ They cannot measure the essentials of effective written communication: accuracy, reasoning, adequacy of evidence, good sense, ethical stance, convincing argument, meaningful organization, clarity, and veracity, among others.
What needs to be taken seriously is not that computers can’t grade as well as humans. In many ways they grade better. More consistently. More honestly. With less grade inflation. And more quickly. But computer grading will be different than human grading. It will be less nuanced and aspire to clearly defined criteria. Are sentences grammatical? Is there a clear statement of the thesis? Are there examples given? Is there a transition between sentences? All of these are important parts of good writing and the computer can be trained to look for these characteristics in an essay. What this means, however, is that computers will demand the kind of clear, precise, and logical writing that computers can understand and that many professors and administrators demand from students. What this also means, however, is that writing will become more mechanical.
There is much to be learned here from an analogy with the rise of computer chess. The great grandmaster Gary Kasparov—who famously lost to Deep Blue— has perceptively argued that machines have changed the ways Chess is played and redefined what a good chess move and a well-played chess game looks like. As I have written before:
The heavy use of computer analysis has pushed the game itself in new directions. The machine doesn’t care about style or patterns or hundreds of years of established theory. It counts up the values of the chess pieces, analyzes a few billion moves, and counts them up again. (A computer translates each piece and each positional factor into a value in order to reduce the game to numbers it can crunch.) It is entirely free of prejudice and doctrine and this has contributed to the development of players who are almost as free of dogma as the machines with which they train. Increasingly, a move isn’t good or bad because it looks that way or because it hasn’t been done that way before. It’s simply good if it works and bad if it doesn’t. Although we still require a strong measure of intuition and logic to play well, humans today are starting to play more like computers. One way to put this is that as we rely on computers and begin to value what computers value and think like computers think, our world becomes more rational, more efficient, and more powerful, but also less beautiful, less unique, and less exotic.
Much the same might be expected from the increasing use of computers to grade (and eventually to write) essays. Students will learn to write in ways expected from computers, just as they today try to learn to write in ways desired by their professors. The difference is that different professors demand and respond to varying styles. Computers will consistently and logically drive writing towards a more mechanical and logical style. Writing, like Chess playing, will likely become more rational, more efficient, and more effective, but also less beautiful, less unique, and less eccentric. In other words, writing will become less human.
It turns out that many secondary school districts already use computers to grade essays. But according to John Markoff in The New York Times, the EdX software promises to bring the technology into college classrooms as well as online courses.
It is quite possible that in the near future, my colleagues and I will no longer have to complain about grading essays. But that is unlikely at Bard. More likely is that such software will be used in large university lecture courses. In such courses with hundreds of students, professors already shorten questions or replace essays with multiple-choice tests. Or they use armies of underpaid graduate students to grade these essays. It is quite likely that software will actually augment the educational value of writing assignments at college in these large lecture halls.
In seminars, however, and in classes at small liberal arts colleges like Bard where I teach, such software will not likely free my colleagues and me from reading essays. The essays I assign are not simple responses to questions in which there are clear criteria for grading. I look for elegance, brevity, insight, and the human spark (please no comments on my writing). Whether or not I am good at evaluating writing or at teaching writing, that is my aspiration. I seek to encourage writing that is thoughtful rather than writing that is simply accurate. When I have time to make meaningful comments on papers, they concern structure, elegance, and depth. It is not only a way to grade an essay, but also a way to connect with my students and help them to see what it means to write and think well.
And yet, I can easily imagine making use of such a computer-grading program. I rarely have time to grade essays as well or as quickly as I would like. I would love to have my students submit drafts of their essays to the EdX computer program.
If they could repeatedly submit their essays and receive such feedback and use the computer to catch not only grammatical errors but also poor sentences, redundancies, repetitions, and whatever other mistakes the computer can be trained to recognize, that would allow them to respond and rework their essays many times before I see them. Used well, I hope, such grading programs might really augment my capacities as a professor and their experiences as students.
I have real fears that grading technology will rarely be used well. Rather, it will too-often replace human grading altogether and in large lectures, high schools and standardized tests will impose a new and inhuman standard on the way we write and thus the way we think. We should greet such new technologies enthusiastically and skeptically. But first, we should try to understand them. Towards that end, it is well worth reading John Markoff’s excellent account of the new EdX computer grading software in The New York Times. It is your weekend read.
We commonly assume that political acts and claims are shaped by some form of reasoning. How then do we respond to political stands in which arguments are piled atop arguments in contradictory ways, and where the force of the various arguments is less important than victory? We see in political discourse a definite willingness to embrace any argument that helps one win, whether or not it makes sense.
One example of our cynical embrace of bad arguments is the recent controversy over the East Side Gallery in Berlin. The Gallery is comprised of a series of murals that, over the course of the past two decades, an international cast of artists has painted and re-painted on an approximately one-mile stretch of the Berlin Wall. Indeed, the East Side Gallery occupies the longest existing remnant of the Wall, and it has become a significant landmark not only for those visitors who seek to experience something of the city’s Cold War past, but also for those long-time residents who regard it as an embodiment of the city’s contemporary feel and texture.
The tumult of the past few weeks erupted over the plans of a developer, Maik Uwe Hinkel, to construct luxury apartments and an office complex in the former border zone—now a modest green space—that lies between the East Side Gallery and the Spree River. According to the agreements reached by Hinkel and the local government, these new buildings would entail the creation of an access road and pedestrian bridge to allow passage to pedestrians, bicyclists, and emergency vehicles. The road and bridge, in turn, would require the removal of two stretches of the East Side Gallery and their replacement in the adjacent green space. Local planners had first approved the construction and the alteration to the East Side Gallery back in 2005, and since that time Hinkel’s plans had aroused little concerted opposition.
When workers lifted out one concrete slab from the Gallery on Friday, March 2nd, however, hundreds of demonstrators flocked to the site to prevent any further removals. A group of activists hastily organized a larger demonstration that same weekend, one that ultimately drew a raucous crowd of more than six thousand people. In the face of these surprising protests, Berlin Mayor Klaus Wowereit declared that all further work on the site would be postponed until at least March 18th, when a meeting of the major players would decide its fate. Since then, the developer and the relevant local officials have all declared their eagerness to find a solution that preserves the East Side Gallery in its current state. Even the slab removed earlier this month seems destined to return to its former location.
Yet the apparent success of the protest threatens to overshadow the problematic aspects of the demonstrators’ arguments. On the one hand, many of the organizers and protesters regarded their opposition as a small but significant rejoinder to the insistent tide of commercial development in post-Wall Berlin. To adopt the terms of Sharon Zukin’s recent book Naked City, they saw the East Side Gallery as an embodiment of the city’s distinctive authenticity and rootedness, which they argued should be protected from the homogenizing onslaught of upscale growth and gentrification. To wit, one of the coalitions that spearheaded the protest calls itself “Sink the Media Spree” (Mediaspree Versenken), a name that invokes developers’ recent efforts to transform the area along the river into a headquarters for high-tech communications and media. Its webpage declares that this portion of Berlin should preserve “the neighborhood” as it currently exists and not fall victim to “profit mania” (Kiez statt Profitwahn).
But the East Side Gallery cannot be cast so readily as an incarnation of local authenticity, especially the kind that stands opposed to commerce. First of all, many government actors and city residents were far more eager to see the Wall dismantled in the months and years after November 1989 than to see it preserved, and they condoned if not actively contributed to its wholesale removal. As a result, the survival of the East Side Gallery represents the exception, not the rule, in the city’s engagement with the Wall as a material structure. Second, artists from around the world initially established the East Side Gallery as a celebration of artistic and political liberty, but their murals received support from the local and national governments because they helped to draw tourists to Berlin and added to the city’s cachet as a cultural destination. In the light of this state patronage, I find it rather curious to hear activists pitching the East Side Gallery against the forces of capital and development.
On the other hand, many demonstrators contended that the alteration of the East Side Gallery would amount to an intolerable attack on the city’s historical inheritance. One variation of this position is that the removal of the two sections constitutes a dilution if not erasure of Germany’s traumatic past. According to this argument, the East Side Gallery should be left intact so that residents and visitors can confront the traces of the country’s division. Another, more strident variation insists that the construction plans display a callous disregard for those who suffered under the East German regime and, more specifically, lost their lives while attempting to escape it. In the words of one activist in Der Tagesspiegel: “the most important point is not whether the Wall will be opened. We are against the combination of removing the Wall and building hotels and apartments in death strips.”
Again, the East Side Gallery’s connection with Germany’s fraught past is not nearly as straightforward as the activists and demonstrators have suggested. As Brian Ladd details in his book The Ghosts of Berlin, the murals of the East Side Gallery were not painted until the early 1990s, after the Wall had fallen and East Germany had ceased to exist. In fact, this portion of the Wall could not have been painted before 1989, because it stood in East Berlin, and anyone who attempted to leave a mark on it, or even lingered near it, would have been apprehended by East German police officers or border soldiers. Of course, amateur and professional artists did draw and paint some striking imagery on the Berlin Wall during the Cold War, but they created it on the Wall’s “outer” surface while standing in West Berlin, where they had much less to fear from East German border personnel. The muralists who launched and maintained the East Side Gallery certainly meant to evoke and further this tradition of “Wall art,” but in the process they abstracted it from a prior historical era and relocated it in another part of the city.
I note these objections not because I support the proposed construction or the alteration of the East Side Gallery. In particular, I am not at all convinced that the partial removal of the Wall is really necessary, whether or not Hinkel and the city go ahead with the area’s development. But I am troubled by the protesters’ reluctance to take the ironies and complexities of the current circumstances more fully into account. They are too eager to cast the developer and local officials as the villains in this story, particularly when the city and the federal government have in fact created a substantial memorial landscape related to the Wall. And they are too quick to position themselves on the moral high ground. Given the Wall’s disappearance from virtually every other part of the city, their demands for preserving the East Side Gallery seem more than a little belated.
San Jose State University is experimenting with a program where students pay a reduced fee for online courses run by the private firm Udacity. Teachers and their unions are in retreat across the nation. And groups like Uncollege insist that schools and universities are unnecessary. At a time when teachers are everywhere on the defensive, it is great to read this opening salvo from Leon Wieseltier:
When I look back at my education, I am struck not by how much I learned but by how much I was taught. I am the progeny of teachers; I swoon over teachers. Even what I learned on my own I owed to them, because they guided me in my sense of what is significant.
I share Wieseltier’s reverence for educators. Eric Rothschild and Werner Feig lit fires in my brain while I was in high school. Austin Sarat taught me to teach myself in college. Laurent Mayali introduced me to the wonders of history. Marianne Constable pushed me to be a rigorous reader. Drucilla Cornell fired my idealism for justice. And Philippe Nonet showed me how much I still had to know and inspired me to read and think ruthlessly in graduate school. Like Wieseltier, I can trace my life’s path through the lens of my teachers.
The occasion for such a welcome love letter to teachers is Wieseltier’s rapacious rejection of homeschooling and unschooling, two movements that he argues denigrate teachers. As sympathetic as I am to his paean to pedagogues, Wieseltier’s rejection of all alternatives to conventional education today is overly defensive.
For all their many ills, homeschooling and unschooling are two movements that seek to personalize and intensify the often conventional and factory-like educational experience of our nation’s high schools and colleges. According to Wieseltier, these alternatives are possessed of the “demented idea that children can be competently taught by people whose only qualifications for teaching them are love and a desire to keep them from the world.” These movements believe that young people can “reject college and become “self-directed learners.”” For Wieseltier, the claim that people can teach themselves is both an “insult to the great profession of pedagogy” and a romantic over-estimation of “untutored ‘self’.”
The romance of the untutored self is strong, but hardly dangerous. While today educators like Will Richardson and entrepreneurs like Dale Stephens celebrate the abundance of the internet and argue that anyone can teach themselves with simply an internet connection, that dream has a history. Consider this endorsement of autodidactic learning from Ray Bradbury from long before the internet:
Yes, I am. I’m completely library educated. I’ve never been to college. I went down to the library when I was in grade school in Waukegan, and in high school in Los Angeles, and spent long days every summer in the library. I used to steal magazines from a store on Genesee Street, in Waukegan, and read them and then steal them back on the racks again. That way I took the print off with my eyeballs and stayed honest. I didn’t want to be a permanent thief, and I was very careful to wash my hands before I read them. But with the library, it’s like catnip, I suppose: you begin to run in circles because there’s so much to look at and read. And it’s far more fun than going to school, simply because you make up your own list and you don’t have to listen to anyone. When I would see some of the books my kids were forced to bring home and read by some of their teachers, and were graded on—well, what if you don’t like those books?
In this interview in the Paris Review, Bradbury not only celebrates the freedom of the untutored self, but also dismisses college along much the same lines as Dale Stephens of Uncollege does. Here is Bradbury again:
You can’t learn to write in college. It’s a very bad place for writers because the teachers always think they know more than you do—and they don’t. They have prejudices. They may like Henry James, but what if you don’t want to write like Henry James? They may like John Irving, for instance, who’s the bore of all time. A lot of the people whose work they’ve taught in the schools for the last thirty years, I can’t understand why people read them and why they are taught. The library, on the other hand, has no biases. The information is all there for you to interpret. You don’t have someone telling you what to think. You discover it for yourself.
What the library and the internet offer is unfiltered information. For the autodidact, that is all that is needed. Education is a self-driven exploration of the database of the world.
Of course such arguments are elitist. Not everyone is a Ray Bradbury or a Wilhelm Gottfried Leibniz, who taught himself Latin in a few days. Hannah Arendt refused to go to her high school Greek class because it was offered at 8 am—too early an hour for her mind to wake up, she claimed. She learned Greek on her own. For such people self-learning is an option. But even Arendt needed teachers, which is why she went to Freiburg to study with Martin Heidegger. She had heard, she later wrote, that thinking was happening there. And she wanted to learn to think.
What is it that teachers teach when they are teaching? To answer “thinking” or “critical reasoning” or “self-reflection” is simply to open more questions. And yet these are the crucial questions we need to ask. At a period in time when education is increasingly confused with information delivery, we need to articulate and promote the dignity of teaching.
What is most provocative in Wieseltier’s essay is his civic argument for a liberal arts education. Education, he writes, is the salvation of both the person and the citizen. Indeed it is the bulwark of a democratic politics:
Surely the primary objectives of education are the formation of the self and the formation of the citizen. A political order based on the expression of opinion imposes an intellectual obligation upon the individual, who cannot acquit himself of his democratic duty without an ability to reason, a familiarity with argument, a historical memory. An ignorant citizen is a traitor to an open society. The demagoguery of the media, which is covertly structural when it is not overtly ideological, demands a countervailing force of knowledgeable reflection.
That education is the answer to our political ills is an argument heard widely. During the recent presidential election, the candidates frequently appealed to education as the panacea for everything from our flagging economy to our sclerotic political system. Wieseltier trades in a similar argument: A good liberal arts education will yield critical thinkers who will thus be able to parse the obfuscation inherent in the media and vote for responsible and excellent candidates.
I am skeptical of arguments that imagine education as a panacea for politics. Behind such arguments is usually the unspoken assumption: “If X were educated and knew what they were talking about, they would see the truth and agree with me.” There is a confidence here in a kind of rational speech situation (of the kind imagined by Jürgen Habermas) that holds that when the conditions are propitious, everyone will come to agree on a rational solution. But that is not the way human nature or politics works. Politics involves plurality and the amazing thing about human beings is that educated or not, we embrace an extraordinary variety of strongly held, intelligent, and conscientious opinions. I am a firm believer in education. But I hold out little hope that education will make people see eye to eye, end our political paralysis, or usher in a more rational polity.
What then is the value of education? And why is that we so deeply need great teachers? Hannah Arendt saw education as “the point at which we decide whether we love the world enough to assume responsibility for it." The educator must love the world and believe in it if he or she is to introduce young people to that world as something noble and worthy of respect. In this sense education is conservative, insofar as it conserves the world as it has been given. But education is also revolutionary, insofar as the teacher must realize that it is part of that world as it is that young people will change the world. Teachers simply teach what is, Arendt argued; they leave to the students the chance to transform it.
To teach the world as it is, one must love the world—what Arendt comes to call amor mundi. A teacher must not despise the world or see it as oppressive, evil, and deceitful. Yes, the teacher can recognize the limitations of the world and see its faults. But he or she must nevertheless love the world with its faults and thus lead the student into the world as something inspired and beautiful. To teach Plato, you must love Plato. To teach geology, you must love rocks. While critical thinking is an important skill, what teachers teach is rather enthusiasm and love of learning. The great teachers are the lovers of learning. What they teach, above all, is the experience of discovery. And they do so by learning themselves.
Education is to be distinguished from knowledge transmission. It must also be distinguished from credentialing. And finally, education is not the same as indoctrinating students with values or beliefs. Education is about opening students to the fact of what is. Teaching them about the world as it is. It is then up to the student, the young, to judge whether the world that they have inherited is loveable and worthy of retention, or whether it must be changed. The teacher is not responsible for changing the world; rather the teacher nurtures new citizens who are capable of judging the world on their own.
Arendt thus affirms Ralph Waldo Emerson's view that “He only who is able to stand alone is qualified for society.” Emerson’s imperative, to take up the divine idea allotted to each one of us, resonates with Arendt’s Socratic imperative, to be true to oneself. Education, Arendt insists, must risk allowing people their unique and personal viewpoints, eschewing political education and seeking, simply, to nurture independent minds. Education prepares the youth for politics by bringing them into a common world as independent and unique individuals. From this perspective, the progeny of teachers is the educated citizen, someone one who is both self-reliant in an Emersonian sense and also part of a common world.
