Kenyon professors shed light on some questions that won’t leave us alone.
Driven by our own curiosity, we posed five burning questions to some of the smartest, most thoughtful people we know — Kenyon faculty members. As masters of their subjects, each one is well-qualified to offer not necessarily definitive answers, but insightful observations informed by their scholarly expertise. We learned a lot, and we hope you will, too.

Unmitigated climate change poses an existential threat to our way of life. A major economic study projects a long-term 20 percent reduction in global gross domestic product from climate change. To avoid such unprecedented declines, we must reduce our greenhouse emissions in the U.S. by 80 percent by 2050. This goal is realistic, but a major undertaking that requires deliberate action.
Numerous economic models demonstrate that transitioning to renewable energy is likely to result in a net economic gain for our society. That does not mean that every individual will benefit, nor that the transition with be without pain, but it does mean that the transition is likely to result in more jobs and a more efficient and resilient electricity system.
A recent study by the Risky Business Project provides a frame-work for an approach that is both technically and economically feasible. It is based on three principal transitions: shifting from fossil fuels to electricity, generating electricity from low- and zero-carbon sources, and using all energy more efficiently.
The shift from fossil fuels to electricity includes the gradual adoption of electric vehicles, electric and geothermal heat pumps, and electricity in industrial processes. The shift to renewable electricity production requires a rapid transition to zero-carbon sources, like wind, solar, geothermal and nuclear, along with an expansion of energy-storage technologies and a redesigned grid to reduce the variability impacts of wind and solar. The potential for increased efficiency in energy use is significant, as we lose about half of all electricity generated in the U.S. to system losses. A redesigned distributed-generation grid could dramatically reduce those losses.
The cost of this particular plan would be around $320 billion a year from 2020 to 2050, but the returns over the life of the transition would be substantially larger and would continue indefinitely. The savings would start at around $65 billion a year in the 2020s, increasing to over $700 billion a year in the 2040s. Around 1 million additional jobs would be created during the 30-year transition, with many of the largest gains being in the domestic construction and utilities sectors. While other approaches may offer greater or fewer costs or benefits, the important point is that the renewable energy transition can be a win-win proposition for our economy.

Scientists have been manipulating DNA for decades, but early genetic-manipulation techniques were slow, expensive and geared to individual species. Enter CRISPR — a fast, cheap and flexible way to make precise changes in any cell’s DNA.
CRISPR’s enormous promise has both scientists and investors aggressively seeking new therapeutic applications, including altering a gene within retinal cells to restore sight to patients with a rare cause of heritable blindness.
A more ambitious goal is to modify the “germ line,” the cells that give rise to sperm and egg, thereby creating genetic alterations that could be passed on to a patient’s children. The hope would be to eliminate inherited diseases like cystic fibrosis, muscular dystrophy or Huntington’s disease. Edits in the human germ line must be made on in-vitro-fertilized human embryos. And that’s where serious concerns arise.
First, CRISPR technology is not yet safe enough for medical use in human embryos. In early attempts to perform CRISPR edits in an embryo, scientists based in China detected unanticipated changes at multiple sites in the genome, which might have caused birth defects or diseases if the embryo had been brought to term. Recent attempts in an American lab were more encouraging, but improved accuracy resulted from unexpected and poorly understood biochemical mechanisms.
While some medical scientists argue that it’s morally wrong to withhold the cure to a genetic disease, the alteration of the human genome raises profound ethical questions. What if we used technology to select specific traits in offspring — height, skin color or intelligence? How would widespread genome editing affect the population genetics of our species in the future? If a sophisticated experimental technique like CRISPR is available only to the rich, could it exacerbate and entrench economic inequality at the biological level?
Issues such as these cry out for international consensus. For now, the laws of many Western European countries and the policies of American research agencies establish a moratorium on genetic manipulation of the human germ line. But a panel from the U.S. National Academy of Sciences recently issued a report exploring the way forward for human gene therapy. Inaction by society is not an option. It is crucial that the pace of policymaking match the inevitably rapid advancement of genome-editing technology.
A: IVONNE GARCÍA | ASSOCIATE PROFESSOR OF ENGLISH AND LITERATURE
In September 2018, Merriam-Webster announced that it was officially adding the word Latinx to its dictionary, a word its editors had begun “watching” for inclusion the year before. The Oxford English Dictionary, meanwhile, has not officially recognized the word, but does include Latinx (pronounced la-TEEN-ex) in its free online resource.
For many of us in the Latinx community, who’ve been using the term to describe ourselves and our community as part of a multi-racial pan-ethnic U.S. population of Latin American/Caribbean descent, these changes have been long in coming.
So why Latinx? Why not just Hispanic?
For one, Hispanic is a term that was officialized by the U.S. Census in 1980 after some prior unsuccessful attempts to accurately include this rapidly growing population into its calculations and projections. But that term comes from the Spanish word hispano, which usually referred to Spanish people settled or born in Latin America. The word, therefore, privileges the white Spanish-speaking legacy of our common history, erasing the indigenous, African and other bloods (Corsican, Irish, Italian, French and Caribbean, just to name a few in my own ancestry) that contributed to forging our communities.
For me, the term Latinx more clearly signifies our mixed-race, multicultural, multinational, multilingual Latin American legacy, while also refusing the gendered binary that is inherent to the Spanish language. As anyone who speaks Spanish (or other Romance languages) knows, most tongues descended from Latin have lost the gender-neutral nouns. In Spanish, this means that nouns end in -o (for masculine) or -a (for feminine). More egregiously, the plural of these nouns is always masculinized so that my brother, my sister and I, as siblings, were always hermanos, and the hijos of my parents, never the other way around.
In years past, many in the Latinx community (myself included) tried to get around this problematic reification of masculinity by first using a slash (Latino/a) and later using the at symbol (Latin@). But that still acknowledged only a gender binary, actively excluding our LGBTQ+ community.
There are those who point to the fact that Latinx is still connected to the socio-historical-cultural construct of what is (and isn’t) Latin. And that’s true. Indeed, no word in English or Spanish can ever be “innocent” of the colonial context in which it has been engendered. And it’s clear that the forces of that coloniality, or the way the legacies of colonialism assert themselves, extend to race, gender, sexuality and ethnicity, just to name a few of the “asymmetries of power” produced in and reproduced by the colonial “contact zones” that created us.
But to me, Latinx seeks to interrogate those asymmetries and provides a way to challenge the manner in which language functions as an accomplice to the power structures most of us struggle against on a daily basis.
In the end, however, this isn’t a settled question, not even among Latinx peoples, many of whom may prefer the term Hispanic, or even another term, such as Mexican-American or Boricua. The point is for us to know the difference between these terms and to understand that this isn’t a “one name fits all” situation.
After all, one of the key lessons of any and all colonialisms is that people should have a fundamental right to choose how they identify, rather than to have an identity imposed on them. And, yes, that makes the work of coming together more challenging. But isn’t that, ultimately, what the imperative work of inclusion means?
A: JAY CORRIGAN | PROFESSOR OF ECONOMICS
In a 1987 New York Times op-ed, Nobel Prize-winning economist Robert Solow quipped that “you can see the computer age everywhere but in the productivity statistics.” Solow’s paradox, as it’s known by economists, is even more puzzling in today’s hyper-connected world. The internet, social media, smartphones and fast ubiquitous wireless networks have changed our lives so completely that it’s hard to imagine what college was like before Facebook, let alone Google. (And I say that as someone who went to college before Google existed.) Indeed, when I ask my students if they’d accept $1 million today in exchange for never again going online, virtually all say “no.”
Despite these rapid changes, computers haven’t made us more productive at work. Businesses only spent a tenth as much on IT in the 1950s and 1960s as they do today, but output per worker during that time grew almost a percentage point per year faster than it has in the decades since. One percentage point might not sound like a big difference, but it adds up quickly through the magic of compound growth.
Of course, even economists know there’s more to life than work. Could the internet be making us better off without making us better at our jobs? What if free services like Facebook, Twitter, Instagram and YouTube make us much happier even if they don’t contribute much to national income? I tried to answer this question by working with a team of researchers from Michigan State, Tufts and Susquehanna universities. We offered cash to four different populations of Facebook users in exchange for deactivating their accounts for time periods ranging from one day to one year.
This wasn’t a hypothetical exercise. We offered real money, and people didn’t get paid until they proved they’d deactivated their accounts. We consistently found that the average user would have to be paid more than $1,000 to deactivate their account for a year. If our samples were at all representative of the larger U.S. population, Facebook creates hundreds of billions of dollars in value for its users each year, but it does this while employing just 1 percent as many people as Walmart.
So it turns out Solow was right. Cat videos and status updates don’t create a lot of jobs or make us better at our jobs. But social networks like Facebook provide users with tremendous value at no out-of-pocket cost. That helps explain why it feels like the computer age has changed our lives even if it doesn’t show up in the productivity statistics.

When IBM Deep Blue defeated chess champion Garry Kasparov in 1997, The New York Times reported it would take 100 years before a computer could defeat a human Go master. Go is a vastly more complex game than chess that requires computers to rely on heuristic shortcuts that mimic human intuition.
Yet it was just 20 years later when AlphaGo twice defeated Lee Sedol, an 18-time world Go champion, and became the first computer to beat a top-ranked human in a Go match.
Astonishing advances like this have led to a global “arms race” in artificial intelligence, as companies compete to acquire top AI talent. Last year, China announced a multibillion-dollar initiative to become the world leader in AI and, recently, Russian President Vladimir Putin proclaimed, “Whoever becomes the leader in this sphere will become the ruler of the world.”
While AI experts work to develop smarter AI applications for all of us — from driverless cars to personal assistants — fewer have taken up the broader challenge to ensure we don’t become, in Henry David Thoreau’s words, “the tools of our tools.”
What we need now are humanists conversant in AI who can critique and shape the future that AI may restructure. After all, AI forces us to ask questions about what it means to be human. And answering these questions will, in the end, be more important than AI milestones like AlphaGo. The only way to answer these questions is to develop an understanding of the world that is both broad and deep, since these questions cannot be answered within any single discipline or major.
No one in 1997 could have predicted the advances in big data, computational power and algorithms that are making AI increasingly powerful and inexpensive. How, then, can we predict what AI will look like 20 years from now? Even the experts are poor at forecasting this future. But the rapid and revolutionary changes being brought on by AI compel us to continue putting the human at the center of our technological world.

A: SEAN DECATUR | President of Kenyon College
The free exchange of ideas is central to the values of a liberal arts education: Colleges and universities should be places where ideas are contested and challenged, not suppressed or shut out. At Kenyon, our faculty has endorsed this concept with a resolution on the value and importance of free expression, emphasizing that we must be open to hearing ideas that are inconsistent with shared institutional values.
But how do colleges resolve the tension between their institutional charge to promote freedom of speech and expression on the one hand, and to establish a site of civil discourse on the other?
There are two components to consider. One is that speech or expression may be permitted, but that does not mean that it comes without consequences. Freedom of speech is not freedom from rebuke. In fact, if one follows the “marketplace of ideas” concept of Oliver Wendell Holmes, the rebuke is essential, since it is in the public challenge and battle over speech that our cultural norms of civility get established.
The other component is that institutions can and must set ground rules to ensure that free speech occurs within some bounds of acceptable civil discourse. Do you have the right to protest on campus? Yes, but the institution has the right to set the rules to make sure that all voices can be heard.
Today’s political climate dictates that the tension between free speech and civil discourse will continue in national conversation, and undoubtedly college campuses will continue to be flash points in these discussions. If we think of society as a marketplace of ideas, college campuses are the sites of market disruption — where new ideas challenge (and at times overthrow) old ones, new paradigms get established, and the battles over defining civility get waged.
Yes, let’s be unafraid to exchange ideas freely on campus. But when speech or actions disrupt accepted notions of civility, let’s also be unafraid to call attention to that with clear rebuke or rejection. This tension between civility and free speech will lead the way to progress.
A: GLENN MCNAIR | Professor of History
The simple, but disappointing, answer is that we cannot break down systemic racism within the judicial system until we have made significant inroads in eroding white supremacy itself. White supremacy is defined as an ideology based on the belief that whites are superior to other races and is manifested through systems that maintain whites in superior positions.
The most cutting-edge research on implicit bias, including research conducted by Harvard’s Project Implicit, confirms that most Americans associate Blacks with crime and violence. Until fairly recently, these beliefs were held consciously and articulated publicly. Today, these beliefs are largely unconscious, but nevertheless play a significant role in decision-making processes. Accordingly, when actors within the criminal justice system make decisions, they act on these biases — even if they are not aware of them.
Bias in the criminal justice system begins with police officers; they decide who to stop and frisk or to arrest. Study after study demonstrates that police officers bring Blacks into the system with far greater frequency than whites. The process continues with prosecutors deciding whether to charge those arrested, take them to trial, or urge them to enter guilty pleas. Again, fewer whites are charged, compelled to enter guilty pleas, or sent to trial. At conviction, judges decide punishments. Blacks routinely receive harsher punishments than whites, up to and including the death penalty. Before judges can hand down sentences, juries must determine guilt or innocence. Juries convict black defendants at higher rates than white defendants.
A seemingly straightforward way of handling this problem of discretion is to eliminate it by crafting strict guidelines about what to do at each stage of the process. This has been tried since the 1970s and has failed, or has produced horrific unintended consequences. For example, mandatory-minimum sentencing was designed to ensure that all criminals convicted of particular crimes would receive similar punishments. That reform is responsible for today’s mass incarceration crisis.
In sum, we cannot make progress within the criminal justice system until we deal with white supremacy in our society as a whole. And the first step in that process is acknowledging that it is a problem, something we have been loathe to do.

A: TOM GIBLIN | Associate Professor of Physics
The good news is that physicists have developed complete, tested and verified models of time travel that perfectly explain how objects (including humans!) can, and do, travel through time. The bad news is that it’s the ultimate one-way street. We constantly are traveling through time, but our velocity in that direction is, with all the unfortunate consequences, unstoppable.
The theories of special and general relativity fully explain the rich physics of how to manipulate the rate at which clocks can tick due to large relative velocities and/or different altitudes — not to mention the even more significant effects of strong gravitational fields or near-light speed travel. It’s unavoidable to draw the analogy between these models and humans’ perception of how quickly time seems to pass; an hour in lecture can seem like a minute or a day depending on your frame of mind.
Understanding time travel, at least in this sense, is more than an academic exercise. The observable consequences of relativity are relevant in many of the processes that we take for granted. For instance, not a day goes by that I don’t rely on my GPS to tell me how long it will take for me to get home. This technology would be useless without a careful understanding of why the clocks on the GPS satellites tick at a (relative) different rate to those we have in our phones.
The great mystery, however, is not the fact that we travel through time in one direction, but rather why we travel in one direction. Macroscopic physics — thermodynamics, to be exact — dictates the rules that compel us forward, and forbid us to travel backwards, through time. On the other hand, microscopic physics has (almost) nothing to say about the choice of early versus late or young versus old. All microscopic laws of physics are time-reversal symmetric, meaning that these laws don’t care if time goes forward or backward. The origin of the arrow of time, the principle that dictates that we bleed after we’re cut, is an open question in physics.
In short, we’re great at time travel; we know a lot about how time works and have harnessed its power in multiple ways. The limitations of this model that get us down, but these same limitations help our GPS get us to where we need to go.
A: GEORGE GOLDMAN '20 | History Major from Boston
This question reminds me of a history class I took called “Modern History of the Middle East.” In the class, we learned about the recent wave of protests and revolutions (the Arab Spring) that took place from 2010 to 2012 throughout the Middle East in countries like Tunisia, Egypt and Syria. We discussed how protests often happen in cycles; in other words, they come about as a part of a larger historical pattern in which revolts of collective action against the government rise, fall, and make way for the next cycle to continue the trend.
For instance, the Young Turks Revolution of 1908, the Egyptian Revolution of 1952, and the Iranian Revolution of 1978-79 each were a part of a distinct protest cycle in which the people rose up against the government. However, history did not completely repeat itself in each case. The methods and eventual outcomes of the protests all were very different.
American writer Mark Twain once said, “History doesn’t repeat itself, but it often rhymes.” After taking “History of the Modern Middle East,” I learned how the Arab Spring protests were not a complete repeat of history, but instead a sort of rhyme with history. For sure, ideas, goals and traditions continued from one protest cycle to the next, but the kinds of people protesting and the results of the protests were often very different. As a history major myself, I have learned that your question is one that has kept many a historian busy.

For most of human history, automation has dramatically increased our material comfort, wealth and well-being, freeing humans from the “3 Ds” of “dull, dirty and dangerous” work while providing new and more stimulating work opportunities. The majority of us believe our jobs will remain immune, and that automation will augment rather than replace human labor.
But recently, anxiety about automation has increased. Automation is suspected of playing a role in the stagnant wage growth and underemployment that has plagued developed economies for the past half century. Artificial Intelligence also is demonstrating the potential to automate almost every human activity.
The newest wave of AI-powered automation is less about automating simple physical labor and more about empowering automation with human-like perception, communication and cognition. Studies have found that up to half of existing jobs are at risk for automation within two decades, and it’s possible AI will outperform humans in all work tasks within 45 years.
Still, some “dull and dirty” jobs pose real challenges to automation. Ironically, AI turns out to be better at manipulating abstract symbols, exploring innovative designs, and sensing human emotions than cleaning toilets. Imagine a future dystopia in which we clean toilets while AI writes symphonies, serializes TV shows and crunches numbers to make life’s important decisions.
What can we do as a society if many of us cannot compete with automation for traditional jobs and new job creation fails to keep pace? Small scale experiments in Universal Basic Income are testing it as a viable alternative to a work-based economy. Taxing robots in proportion to the human labor they replace may preserve government revenue and slow its adoption. Congress has banned self-driving trucks, and human oversight is mandated for data-driven criminal sentencing and medical diagnosis.
Still, there remains the question as to how individuals will reimagine their purpose and identity without work. Automation may force us to rethink the fundamental premises of our economy, laws and ethics as it accelerates wealth concentration, creates vast power imbalances and swiftly outmaneuvers any regulations designed to control it.
We all need to ask and answer these big questions to ensure that an automated world is still one we wish to inhabit. Only in doing so can we determine how to maintain a humanist world in the face of an increasing post-humanist onslaught.
A: CHRIS PALUDI ’20 | Political Science Major from Los Angeles
just completed a final exam on a similar question in my “International Relations” class, where we talked extensively about this issue. Though we didn’t achieve world peace in a semester, the class did shed some light on why the largest nations in the world have enjoyed a long period of peace and prosperity after World War II, but why the world is, in some ways, a much less stable place than it was 20 years ago.
The world is a dangerous place, and countries’ first priority in their international relations is their own security. With no one to protect them, they have to protect themselves, and to do so, they arm themselves. If everyone is arming themselves, there is no way to really know whether or not someone with the ability to hurt you is simply protecting themselves or is preparing to attack. The only way to be safe is to make sure you’re the strongest one around. If you’re thinking, “That sounds like an arms race,” well, you’d be right. That’s why most countries agree on rules that help everybody feel safer.
Ever since World War II, the U.S. has been a “global policeman” that enforces these rules. To prevent the insecurity that makes the international system so dangerous, the U.S. makes it clear that we're ready to use our power to stand up for our allies if they're attacked. Since the 1940s, America has accumulated binding promises to protect almost 70 countries across the globe, from NATO nations to Japan and South Korea. And since the U.S. is not a country others have wanted to mess with, things have been pretty peaceful from a historical perspective.
The world also has a neighborhood watch in the United Nations, which helps countries talk things out as much as possible. Countries also trade more today than ever before, and are pretty interdependent in ways that have made peace and prosperity not only possible but probable. That wasn’t something you could count on for most of history. And when that situation gets more dicey, like today, countries flex their muscles in nonviolent ways to maintain the status quo. We’ve found that smart, strong sanctions and even public pressure can often prove really useful to changing behaviors.
Unfortunately, humans haven’t figured out how to simply negotiate our way out of every disagreement. We may never will. Acknowledging this ugly reality, we should all be more empathetic and seek to understand and respect other states and other cultures. Doing so may help prevent misunderstandings and adversarial attitudes that lead to violence where it need not arise.
