Three thinkers on when we should call out harmful speech

What speech is harmful, how do we know, and what do we do if we find out?

  • Modern debates over free speech rage on the internet, but what do experts say?
  • Some think it is easy to go too far in limiting public debate by offending parties, others argue limits are part of normal discourse.
  • While the debate isn't settled, these thinkers can give you some starting points for your next discussion.

If you've been online in the past few weeks, you've probably come across at least one person discussing free speech. The debate over if it is threatened, who has it, who needs it, what it is, and what form it should take goes back long before the days of social media and the 24-hour news cycle.

Recently, the debate over what limits are being put on public discourse is the center of attention, with a great deal of focus placed on the question of what conversations are worth having. Some, including the signers of the famous Harper's Letter, fear that free speech is threatened. Their detractors fear this is a front to keep the traditionally marginalized from expressing their concerns. Previous controversies have centered around who gets to speak at what institutions and if the withdraw of an invitation to speak, or the denial of it to begin with, is a kind of censorship.

But, are any of these concerns valid? What do experts on argumentation have to say about these issues? Today, we'll consider three experts' stances on when speech can be harmful, when people shouldn't be given a platform, and when we should grit our teeth and suffer their opinion.

Stance #1: Meta- argumentative allegations are a tool that should be used sparingly. 

Dr. Hugh Breakey of Griffith University lays out his case in the essay "'That's Unhelpful, Harmful and Offensive!' Epistemic and Ethical Concerns with Meta-argument Allegations."

Breakey argues that "meta-arguments," statements that focus on external features of an argument rather than an argument's soundness, can be used to critique arguments by pointing out the harm that an argument might cause.

As an example, imagine that somebody tells an armed mob without evidence that grocers are the cause of a crippling food shortage. Pointing out that this argument might cause harm provides an ethical good (the speaker might not make the argument now that they know harm may come of it) and an epistemic good (the argument might be improved or abandoned if the weakness of it is pointed out). While meta-arguments aren't good or bad by themselves, this example shows how they can be used positively.

However, other times critiques that seem clear to one party in an argument can seem groundless to others. In these cases, meta-arguments can derail discussion rather than clarify it. Worse, it can be impossible to get back on track after these allegations are made.

Big Think reached out to Dr. Breakey, who offered this elaboration on his position:


"When we call out what someone says in an argument as offensive, harmful or unhelpful, it can feel like we are applying an impartial standard. We're setting down sensible, objective rules within which constructive civil debate can occur. But the reality is that our judgments about such matters are likely to be as controversial and contestable—and, unfortunately, influenced by emotional and cognitive biases—as our views on the original topic of the debate. Reasonable people can disagree on the risks of harm created by speech, the ethical weight that should be given to those harms, where the moral responsibility for those harms properly lies, and how these factors relate to the importance of freely discussing the original topic of the debate. These are all complicated and difficult questions, and will be answered differently by people with different political views and life experiences. As a result, we need to exercise great caution in leveling allegations of harm and offence during an argument. Otherwise, the very differences that led to the original debate—and that make that debate worthwhile—will be used to foreclose it."


Given these concerns, the essay ends with a call for "argumentational tolerance" that is weary of using meta-argumentative allegations in general, but is open to using them when the speech in question is obviously harmful, such as instances of hate speech or calls to violence.

Stance #2: Platforms lend credence, and some people shouldn't be given that.

Another stance is taken by Professor Neil Levy of The Oxford Uehiro Centre for Practical Ethics, in their essay "Why no-platforming is sometimes a justifiable position."

They agree with many others that free speech is valuable and that good-faith arguments are generally good. However, they find the idea of deplatforming for meta-argumentative reasons more compelling than others might.

In Dr. Levy's essay, they ask you to imagine that a university has invited a speaker who rejects climate change's existence to speak on that topic. While that position is bunk, the very act of being invited to speak by a prestigious university grants credence to what the speaker has to say, which cannot easily be refuted by other, better arguments.

Things like being invited to speak by a prestigious school or having seemingly valid credentials can be "higher-order" evidence in favor of their position. Higher-order evidence, Dr. Levy explains, influences how we evaluate arguments. Higher-order evidence in favor of our position can make us more confident in it, while opposing evidence can lead us to moderate our stances.

However, Dr. Levy points out the difficulty of countering higher-order evidence, or the legitimacy it confers, by rational argument alone. They further out the usefulness of attacking the credibility of the speaker's bunk arguments by focusing not on the argument but on the higher-order evidence's validity. Here, ad-hominem attacks and meta- argumentative critiques of their speaking at all can remove the higher-order evidence. Deplatforming, often critiqued as the suppression of speech, can also be useful, as it prevents a person from being granted the legitimacy that a speaking invitation can bring.

There is a difference between this position and that of Dr. Breakey. Dr. Levy is more concerned with matters of fact rather than debates over what constitutes acceptable discourse. However, this stance is clearly more open to the idea of using meta-argumental allegations to keep speech non-harmful and productive than other common positions are.

Stance #3: Deciding what speech is “acceptable” is a fundamental aspect of public discourse.

Lastly, we have the stance described by the University of Illinois Professor Nicholas Grossman in an essay titled "Free Speech Defenders Don't Understand the Critique Against Them."

Professor Grossman considers the current debate around "free speech" and suggests that the debate is really over what we consider socially acceptable these days—a discussion which we've had before and will have again.

As he points out, most people would agree that there is nothing wrong with deciding that Holocaust denial is odious. Furthermore, they would likely also agree that private actors can (and should) use their capacities to limit the space available for a Holocaust denier to speak in. Most people would also hardly shed a tear if the denier faced social consequences for their speech. However, not everybody agrees on giving the same treatment to J.K. Rowling in light of her statements concerning transgender individuals.

Professor Grossman argues that our current discussions are really about where the line of "acceptability" is. Are people, like Rowling, crossing that line when they imply transgender women are not women? If so, what social consequences should they face, if any? What else might be on the other side of that line now? How do we know? The line has moved before, consider how common the public use of racial slurs was in the past, is the idea of moving the line now any different?

They agree with Dr. Breakey in thinking that these are big questions without easy answers. However, Professor Grossman suggests that, in determining what speech is socially acceptable, these discussions can, and must, take place for debate to move forward. In contrast, Dr. Breakey suggests that these concerns can derail other debates if not used properly.

How can I use this?

Perhaps the most obvious take away is that all three of these thinkers agree that certain speakers, notably those inciting violence or those deliberately trying to cause harm using racial slurs, can (and perhaps should) be challenged. It suggests a semblance of agreement exists around the idea that some speech does harm and that this legitimizes certain follow up actions to prevent the speech.

This idea is nothing new; even John Stuart Mill agreed with the idea of censoring speech that could cause immediate violence.

The three thinkers considered here also all agree on the importance of open debate in general. None of them are suggesting that you should be arrested for giving an unpopular opinion. They all argue in favor of using reasoned, respectful debate to advance our understanding of various issues.

However, they disagree on how easy it is to know what is respectful debate and what is speech worthy of critique, deplatforming, and social consequence, and what to do when that line is crossed. While the three do seem to be concerned with slightly different scales, Professor Grossman focuses on societal debates while Dr. Levy focuses on institutional level problems, the differences endure, and each stance can be applied at various scales.

Despite this lack of agreement, they all provide strong arguments for their position and a launchpad for further debate. Though, we might need to already agree on a few points before that debate can even happen.

A landslide is imminent and so is its tsunami

  • A remote area visited by tourists and cruises, and home to fishing villages, is about to be visited by a devastating tsunami.
  • A wall of rock exposed by a receding glacier is about crash into the waters below.
  • Glaciers hold such areas together — and when they're gone, bad stuff can be left behind.

The Barry Glacier gives its name to Alaska's Barry Arm Fjord, and a new open letter forecasts trouble ahead.

Thanks to global warming, the glacier has been retreating, so far removing two-thirds of its support for a steep mile-long slope, or scarp, containing perhaps 500 million cubic meters of material. (Think the Hoover Dam times several hundred.) The slope has been moving slowly since 1957, but scientists say it's become an avalanche waiting to happen, maybe within the next year, and likely within 20. When it does come crashing down into the fjord, it could set in motion a frightening tsunami overwhelming the fjord's normally peaceful waters .

"It could happen anytime, but the risk just goes way up as this glacier recedes," says hydrologist Anna Liljedahl of Woods Hole, one of the signatories to the letter.

The Barry Arm Fjord is a stretch of water between the Harriman Fjord and the Port Wills Fjord, located at the northwest corner of the well-known Prince William Sound. It's a beautiful area, home to a few hundred people supporting the local fishing industry, and it's also a popular destination for tourists — its Black Sand Beach is one of Alaska's most scenic — and cruise ships.

There have been at least two similar events in the state's recent history, though not on such a massive scale. On July 9, 1958, an earthquake nearby caused 40 million cubic yards of rock to suddenly slide 2,000 feet down into Lituya Bay, producing a tsunami whose peak waves reportedly reached 1,720 feet in height. By the time the wall of water reached the mouth of the bay, it was still 75 feet high. At Taan Fjord in 2015, a landslide caused a tsunami that crested at 600 feet. Both of these events thankfully occurred in sparsely populated areas, so few fatalities occurred.

The Barry Arm event will be larger than either of these by far.

"This is an enormous slope — the mass that could fail weighs over a billion tonnes," said geologist Dave Petley, speaking to Earther. "The internal structure of that rock mass, which will determine whether it collapses, is very complex. At the moment we don't know enough about it to be able to forecast its future behavior."

Outside of Alaska, on the west coast of Greenland, a landslide-produced tsunami towered 300 feet high, obliterating a fishing village in its path.

"The effects would be especially severe near where the landslide enters the water at the head of Barry Arm. Additionally, areas of shallow water, or low-lying land near the shore, would be in danger even further from the source. A minor failure may not produce significant impacts beyond the inner parts of the fiord, while a complete failure could be destructive throughout Barry Arm, Harriman Fiord, and parts of Port Wells. Our initial results show complex impacts further from the landslide than Barry Arm, with over 30 foot waves in some distant bays, including Whittier."

The discovery of the impeding landslide began with an observation by the sister of geologist Hig Higman of Ground Truth, an organization in Seldovia, Alaska. Artist Valisa Higman was vacationing in the area and sent her brother some photos of worrying fractures she noticed in the slope, taken while she was on a boat cruising the fjord.

Higman confirmed his sister's hunch via available satellite imagery and, digging deeper, found that between 2009 and 2015 the slope had moved 600 feet downhill, leaving a prominent scar.

Ohio State's Chunli Dai unearthed a connection between the movement and the receding of the Barry Glacier. Comparison of the Barry Arm slope with other similar areas, combined with computer modeling of the possible resulting tsunamis, led to the publication of the group's letter.

While the full group of signatories from 14 organizations and institutions has only been working on the situation for a month, the implications were immediately clear. The signers include experts from Ohio State University, the University of Southern California, and the Anchorage and Fairbanks campuses of the University of Alaska.

Once informed of the open letter's contents, the Alaska's Department of Natural Resources immediately released a warning that "an increasingly likely landslide could generate a wave with devastating effects on fishermen and recreationalists."

How do you prepare for something like this?

The obvious question is what can be done to prepare for the landslide and tsunami? For one thing, there's more to understand about the upcoming event, and the researchers lay out their plan in the letter:

"To inform and refine hazard mitigation efforts, we would like to pursue several lines of investigation: Detect changes in the slope that might forewarn of a landslide, better understand what could trigger a landslide, and refine tsunami model projections. By mapping the landslide and nearby terrain, both above and below sea level, we can more accurately determine the basic physical dimensions of the landslide. This can be paired with GPS and seismic measurements made over time to see how the slope responds to changes in the glacier and to events like rainstorms and earthquakes. Field and satellite data can support near-real time hazard monitoring, while computer models of landslide and tsunami scenarios can help identify specific places that are most at risk."

In the letter, the authors reached out to those living in and visiting the area, asking, "What specific questions are most important to you?" and "What could be done to reduce the danger to people who want to visit or work in Barry Arm?" They also invited locals to let them know about any changes, including even small rock-falls and landslides.
