One of the big political challenges we face is deciding what to do about the explosion of disruptive speech. By disruptive speech, I mean speech that challenges or subverts widespread existing social and political norms. There are many kinds of disruptive speech, and not all of them are bad. In fact, as we shall see, some of them are indispensable to a healthy public sphere. However, fake news, where false or misleading stories are smuggled past our epistemic defenses under the cover of journalistic conventions, is one prominent example of what I shall call bad disruptive speech, and we can point to many others such as bald-faced lies, outlandish hyperbole, and hate speech. We are learning just how corrosive bad disruptive speech can be. Increasing numbers of people appear to be turning away from core democratic principles. Foa and Mounk (2017, p. 6–7) cite evidence showing a precipitous drop in the numbers of citizens who believe that it is “essential to live in a democracy,” and, hardly coincidentally, a rise in the number of people who would like to see a strong leader “who does not have to bother with elections.” This chimes with the feeling that many of us have that society is becoming more polarized, and our political disagreements more fractious. Opponents cannot be persuaded or tolerated, and must simply be beaten.1 The label Foa and Mounk attach to growing skepticism about the value of democracy is “deconsolidation,” and this conveys the sense many of us have of something coming apart. Of course, there are many contributory factors that we might discuss. In particular, we might point to structural features of the global economy that concentrate wealth and power in the hands of a fortunate few.2 Some bad behavior in the public sphere may seem of little consequence beside material conditions of inequality, but there are reasons to think that it does matter, even if there are other things that may matter more. This paper addresses three questions. First, does it make sense to group the various kinds of bad disruptive speech together as a distinct family of related threats to broadly liberal representative democracies? Bald-faced lying and hate speech, for example, are clearly wrong for different reasons, so why treat them as if they are the same? Second, how can we distinguish bad forms of disruptive speech from good ones? If the former constitute a clear and present danger to democracy, then we will want to take action to curtail them, but we do not want to throw the baby out with the bathwater. If we are to protect and support good forms of disruptive speech, such as satire and the arts, then we must be able to tell which is which. And, third, what can we permissibly do about bad disruptive speech once we have isolated it? Facebook has appealed to the value of free speech as a justification for continuing to allow demonstrably false political advertising on their platform.3 Is bad disruptive speech simply something that we are stuck with? After showing why we need to employ a wide lens to capture this problem and explaining what I mean by disruptive speech, I argue in Sections 3 and 4 that the common thread linking practices that are primarily wrong for different reasons is that they all eat away at the stability of a democratic society. As I interpret it here, stability is a property of existing political communities. How much of it any particular polity possesses depends on the degree to which its citizens are disposed to play fair with one another and to refrain from imposing their particular conceptions of the good on everyone. Without a high level of stability, it would not be possible to have an open, democratic society, nor would it be possible for such a system to survive political shocks. For these reasons, citizens have a duty to refrain from engaging in bad disruptive speech, and, as a community, we have strong reasons to enact policies that will cultivate, rather than squander, stability. Section 5 illustrates how good forms of disruptive speech help to buttress and secure this form of stability. I motivate the third question by showing in Section 6 how considerations of political legitimacy can give us pause when it comes to discouraging negative forms of disruptive speech. Since it is right to hold that an open and permeable public sphere is non-negotiable for a functioning democracy, we are left wondering what we can permissibly do to combat bad forms of disruptive speech. I argue that we are better placed to identify and evaluate the full range of options for dealing with speech-based threats to political stability when we can distinguish successfully between good and bad disruptive speech. I illustrate this point by sketching the contours of a two-pronged approach we might take. First, we could intervene to encourage good disruptive speech and do more to support those parts of the public sphere where it typically takes place. Second, we can then be more precise in our efforts to target bad disruptive speech. Even if we think that some forms of it must be permitted, it does not follow that it should be tolerated at all times and in all fora. We can, therefore, apply different standards and expectations to different activities, and this means that we can retain an open and permeable public sphere without insisting that we apply the most expansive conception of free speech to all aspects of it. I have said that disruptive speech is speech that challenges or subverts widespread existing norms. What is it for speech to challenge or subvert a norm? I shall follow Jon Elster's (1989a, 1989b) account of norms as shared rules for behavior that are sustained by the approval and disapproval we direct at each other and at ourselves. Norms can thus only be said to come into existence once they have actually been accepted by a group of people. Norms must be sharply distinguished from laws. The latter are backed up by the power of the state, but a system of norms depends on the expectation that if one does her part in upholding them then others will too, which is to say that it relies in large part on trust. To the extent that they are enforced, norms are policed informally using social sanctions such as shaming and ostracism. Elster describes norms as having “a grip on the mind” (1989a, p. 100) because the psychological process of internalizing a social grouping's rules for conduct places them under the auspices of our moral emotions. When we violate norms, we typically feel guilty, or even ashamed of ourselves. When others violate them, it usually sparks feelings of anger and indignation. As an example of disruptive speech that violates norms, let us take the bald-faced lie. A bald-faced lie is a falsehood told with no intention to deceive the hearer.4 According to The Washington Post, the former president of the United States, Donald Trump, made 16,241 false or misleading claims in his first 3 years in office, with the rate increasing markedly in 2019.5 Many of Trump's false claims, such as that there was no “quid pro quo” in his infamous call with the president of Ukraine, can only be sensibly interpreted as bald-faced lies.6 The transcript of the call drips with the implication that continued American aid to Ukraine was connected to the pursuit of an investigation into Trump's political enemies, and, particularly when placed in the context of subsequent revelations that Trump had frozen planned military aid to Ukraine, the truth of the matter is plain.7 Though most observers could see that, Trump, who was facing impeachment proceedings, could not admit it without increasing his legal and political peril. The precedent that he established at the outset of the scandal inspired some Republican senators to hide behind bald-faced lies of their own. Bald-faced lying in politics presents a serious challenge to our collective social assumptions and expectations of honesty and accountability. Not only does the liar violate the ordinary moral duty to tell the truth, they do so flagrantly. Since everybody already knows what the truth is, their lie suggests that the truth does not matter. Whether or not wrongdoers will be held to account then comes to depend on factors that are morally arbitrary, such as the relative political strength of their supporters and opponents.8 Another example of disruptive speech is hate speech which explicitly or implicitly denies the fundamental moral equality of some group of people. In particular, slippery forms of hate speech such as dogwhistles and ostensibly ironic uses of racist or sexist epithets have become increasingly common in our political discourse.9 Badano and Nuti (2018) discuss the example of the French politician Marine Le Pen who often disguises her antipathy to Muslims as a defense of the rights of women and the LGBTQ+ community. This is speech that is designed to challenge and undermine norms of tolerance and respect toward a particular group within a community. However, it is not always straightforward to say precisely why the content of such speech is objectionable. Indeed, one of the reasons why it is effective is precisely because it does such a good job of masquerading as reasonable speech by drawing on the public political culture of the French political tradition.10 While hate speech typically attacks the presupposition that everyone has the same basic standing, more or less directly, the supposedly ironic use of hate speech by some in the so-called “alt-right” movement does so obliquely by undermining norms like those against giving Nazi salutes or using racist epithets that protect against overt hate speech. For one thing, by defending their right to do such things “as a joke,” the strength of the general presumption against doing them at all is weakened.11 For another, it renders the idea of questioning the status of targeted groups salient. As Mary Kate McGowan (2009, p. 403) has argued, undoing the various changes to the local rules and presuppositions of particular conversations that are enacted by racist or sexist jokes can be extremely difficult. Memorably she compares it to trying to “unring a bell.” Note that while disruption and upheaval are often intended, as it is in the case of alt-right activists spreading their beliefs or Russian bots disseminating fake news, it need not be. What matters is that the speaker behaves in such a way that she presents a challenge to the authority of current norms, either by obviously contravening them or by suggesting the adoption of alternative norms that are incompatible with the existing ones.12 Disruptive speech is thus a very broad category. Although I believe there are reasons to think that what I say here applies to all disruptive speech, in what follows I will limit myself to discussion of public disruptive speech, which I understand as disruptive speech that is meant to be heard by many people, most of whom will not be known personally to the speaker. There is an influential liberal tradition stretching all the way back to Mill that embraces all disruptive speech and welcomes the expression of even the most wrongheaded ideas. On the standard Millian line, “[c]omplete liberty of contradicting and disproving our opinion is the very condition which justifies us in assuming its truth for purposes of action; and on no other terms can a being with human faculties have any rational assurance of being right,” (Mill, 1974, p. 79). At the very least, Mill thinks, we should recognize in even the worst forms of speech an opportunity to reinvigorate our own convictions. It is in this vein that Steven Shiffrin (1990, p. 96) asserts that “the sponsoring and protection of dissent generally have progressive implications”.13 Jeremy Waldron's (1987) thoughts on the potential benefits of the experience of being offended offer a possible reason for taking this position one step further. Going beyond the value we may derive from confronting the content of offensive speech, he argues that the experience itself can be something positive as the shock can penetrate our ideological defenses and act as a spur to genuine reflection and growth.14 The controversial Harper's Magazine open letter, which took aim at “cancel culture” and was signed by a number of prominent writers and scholars such as Margaret Atwood and Noam Chomsky, can be read as a contribution to this tradition.15 Notably, the signatories affirm that they “uphold the value of robust and even caustic counter-speech from all quarters,” suggesting that disruptive speech is to be celebrated, and not merely tolerated. Although this approach coheres with mine in so far as it acknowledges disruptive speech as a significant category, it implies that it is unified as a positive one. It is important to see how this view is misguided and why it needs to be more nuanced. If we can successfully establish a clear distinction between good and bad forms of disruptive speech then we stand a much better chance of promoting the former while at the same time discouraging the latter. In this section, I will borrow and adapt John Rawls's idea of stability to argue that bad forms of disruptive speech all undermine democratic models of government by weakening citizens' sense of justice, which is to say the disposition to pass up opportunities to use the power of the state to enforce one's conception of the good on everyone. On my revised understanding, stability is an actual good that existing societies have to a greater or lesser degree, and which can be cultivated with the right policies. What those policies need to get right—and are not currently getting right—is the balance between good and bad disruptive speech. If that analysis is correct, then we face the further question of what to do about it. This paper is an exercise in non-ideal theory and, as such, does not aim to make a contribution to Rawls scholarship. Rawls, of course, was working primarily to determine what justice would look like in an ideal society, one which is well-ordered in the sense that almost everyone in it understands the basic principles of justice and willingly complies with them.16 Clearly, this is not the case in the actual world, and bad disruptive speech as I understand it here is the kind of problem that we have to deal with precisely because some people are not minded to treat others fairly. I borrow the term “stability” from Rawls both because it is intellectually honest to acknowledge his influence on the development of my argument, and because some of the concerns that he raised about our moral psychology seem to me to be crucial for understanding and addressing the current political moment.17 As noted above, we might wonder whether there is any reason to group such disparate activities as fake news and hate speech together. They are obviously wrong for different reasons. Fake news is wrong because it is a form of deception, while hate speech is wrong because it attacks the right to equal standing of some targeted, and usually vulnerable, group. As good philosophers, we ought to distinguish carefully between different categories of wrong. Further, we might worry that running them together will also blind us to important differences in their causes and effects. However, although it is true that these reasons for holding these actions to be impermissible are clearly different, they are not the only reasons why these forms of speech are wrong. The bigger risk is actually that we fail to see the important similarities between them. Alan Wertheimer (1999, p. 15) notes that “when we offer a moral description of an act, we typically invoke the strongest applicable moral description.” Other reasons why the act is bad tend to drop out of view. He calls this the problem of occlusion. I will argue that problematic forms of disruptive speech all share the property of undermining stability. Even though they may also be impermissible for other, often more obvious, reasons, we should not lose sight of the fact that they are wrong for this reason as well.18 This is what will allow us to mark a distinction between good and bad disruptive speech. Although good disruptive speech also breaks conventions and challenges existing norms, by doing so, it builds up stability rather than erodes it. Rawls introduces the notion of stability to help decide between competing conceptions of justice. When conceptions are equally just we can appeal to other advantages they may have, including their stability.19 On this theoretical level, Rawls tells us that a particular conception is more stable “if the sense of justice that it tends to generate is stronger and more likely to override disruptive inclinations and if the institutions it allows foster weaker impulses and temptations to act unjustly” (1999, p. 398). What is it to have a sense of justice? For Rawls (1999, p. 41), a person has a sense of justice if she possesses the intellectual capacity to judge things to be just or unjust on the basis of reasons and is, crucially, motivated to act in accordance with these judgments.20 Even under ideal deliberative circumstances we should expect deep moral disagreements, so there will be many aspects of one's conception of the good that it would not be reasonable to expect other people to accept.21 A person who possesses a sense of justice is prepared to be bound by a system of rules that other people acting in good faith can also find to be acceptable. This is a significant commitment because it means accepting that you cannot have things all your own way, even if your view of what makes for a good society happens to have majority support. You must be prepared to pass up opportunities to further your own view of the good when it would mean violating a set of rules which could, in principle, be justifiable to everyone. It is worth stressing that Rawls is not satisfied by a mere modus vivendi in which fair rules are maintained because no one group has the power to seize control. As Brian Barry (1995, p. 881–882) points out, Rawls is committed to the idea that a truly just society must be one in which its underlying principles are freely accepted by the vast majority of citizens. Similarly, our version of stability must be for the right reasons. Any particular individual's contribution to stability is predicated on their having reasons to develop and preserve an internal disposition to play fair with others and resist temptations to pursue their self-interest when they can see that it would be incompatible with respecting their fellow citizens as political equals. As I shall use it here, stability is not, as Rawls understood it, a property of principles of justice, but rather a property of actual polities. It obtains when a high proportion of the populace have a sufficiently effective sense of justice to allow democratic procedures to operate, more or less, unimpeded and to insulate those procedures from shocks. By the operation of democratic procedures, I mean that governments are elected by popular vote in accordance with the principle of political equality, that they make and successfully enact just laws,22 and that power is transferred peacefully from one regime to the next. By shocks, I mean events such as economic depressions and natural disasters that, while difficult, do not fundamentally alter the conditions of relative scarcity. Of course, in A Theory of Justice Rawls sets out to establish that it is rational for a citizen to maintain a sense of justice by showing that her good is congruent with his principles of justice, but we do not need to attempt anything so ambitious here.23 Rather, it will be enough for our purposes if we can establish that widespread possession of a sense of justice is crucial for the normal operation of democratic politics and to bolster its resilience in trying times. If we can establish that, then it would follow from a deeper duty to support (or at least not harm) democratic institutions in suitably just states that citizens have a duty to refrain from actions that would corrode stability by weakening others' sense of justice. Proving the existence of a duty to support democratic institutions would take me beyond the remit of this paper, but it is well-trodden ground and I think it will suffice to note that on grounds such as political equality it is widely recognized that such a duty does exist. I will offer two arguments for thinking that it is vital for democratic systems that a high proportion of citizens have, and are assumed by one another to have, a robust sense of justice. In the rest of this section, I will use the example of the peaceful transition of power to illustrate the role that a sense of justice plays in underwriting cooperation between representatives of competing comprehensive doctrines. In the next section, I will examine the two threats that Rawls identifies to maintaining a healthy sense of justice and show how disruptive speech can exacerbate both of them. We will see how that, in turn, destabilizes democracies. As Rawls observed, our societies are characterized by deep disagreements about such questions as what constitutes a good life and how we should best organize our communities to facilitate the living of it. This is one reason why politics is often so fractious—there is so much at stake. The prize is the opportunity to use the awesome power of the modern state to reshape society in line with your values. Even in a well-ordered Rawlsian society with constraints such as the demands of public reason placing significant limits on how laws and policies must be justified and applied, there is still enormous scope for office-holders to influence the character of the state and the ways in which it affects the lives of its citizens. In the world as it is, the prize is even more consequential. Bearing this in mind, it is a colossal risk to transfer power to one's political opponents. Not only do you give up the opportunity to wield that power in pursuit of what you think to be right, you hand it over to people with whom you and your voters disagree, perhaps on fundamental moral issues. On a day-to-day basis, you will then be reliant upon the restraint of your political enemies to leave you and yours the space to pursue your conception of the good. You are also counting on them to reciprocate the next time around if, and when, the political tides turn. The peaceful transfer of power between political opponents thus makes no sense unless there is a high degree of trust. More specifically, all sides must trust that everyone will refrain from abusing the coercive power of the state to illegitimately bring about their political goals. What would warrant such a profound form of trust? My contention is that a well-founded belief that your opponents have a motivationally efficacious sense of justice would provide such a warrant. One is justified in assuming that citizens who are like this will not only see why they should resist temptations to abuse power, but are also reliably motivated to do so. This is to say that their possession of a robust sense of justice means that they are trustworthy in a political context. Let us recap the argument so far. Our concern is with how a wide range of speech acts are poisoning our political discourse. To ensure that we capture the wrong that unites all of them, and especially the slippery forms of speech that defy easy categorization, I have suggested that we focus on disruptive speech, which I define as speech that either explicitly or implicitly challenges some widely-accepted norm. My central claim is that bad forms of disruptive speech all share the property of undermining the ability of a democratic system of government to operate effectively, and to be resilient in the face of moderate shocks. In contrast, we will see that good disruptive speech has the opposite effect. In setting out my conception of stability, I have drawn on a modified version of Rawls's notion of a sense of justice. This disposition to be fair in one's dealings with others is not easy to maintain, however. Even though I am proposing an understanding of stability that is significantly different from what Rawls envisaged, one reason for presenting this discussion as an adaptation of his idea is because the main threats he identifies to the stability of his well-ordered society are also challenges to developing and preserving an effective sense of justice in a non-ideal setting. Rawls (1999, pp. 295–296) discusses two chief causes of instability: the attraction of gaining an advantage by ignoring the established rules and the awareness that the same temptation exists for everyone else. Disruptive speech can, of course, attack one's sense of justice directly, as when hate speech is deployed to persuade the members of one group that the members of another group are less than fully human and so unworthy of being treated as equals. However, I contend that the more elusive forms of disruptive speech that I have identified here also have the effect of hollowing out citizens' sense of justice by exacerbating one or both of Rawls's mechanisms of instability. Indeed, this may be one of the primary political motivations for engaging in them. The first cause of instability that Rawls describes is essentially the problem of free-riding. Whenever an individual can benefit from a social rule without contributing to its upkeep there will be an incentive to default. An example of this occurred in the 2019 British general election campaign. During a televised debate between Boris Johnson and Jeremy Corbyn, the Conservative Party changed the name of their official Twitter account to pose as a neutral fact-checking organization. Twitter's accreditation system at that time for official accounts did not anticipate such a move, and so the blue badge that the party had secured remained on the account even though they were now purporting to be impartial observers. To the extent that the move worked, it did so because other verified accounts did not misrepresent their identity and thus gave users reason to trust the system. Disruptive speech like this has multiple effects. A direct consequence in this case is that users' faith in supposedly official online identities will be shaken. There are also indirect consequences when social rules are broken. For one thing, it normalizes rule-breaking behavior, both in particular and in general. Normalization robs the softer social sanctions such as shame of much of their bite and makes it less costly for others to act in a similar fashion. In turn, this changes initial calculations of risk and reward, effectively upping the incentive to break a relevant rule. For another, norm violations make options that were previously unthinkable salient. We saw this in the example of bald-faced lying which was discussed in Section 2. Being caught out in a demonstrable falsehood used to be extremely costly for politicians, and was often fatal for their careers. The only available course of action was to deliver a groveling apology and hope that the outrage would subside. Now, however, politicians are keenly aware that there are alternatives, such as doubling down or brazening it out. When options like this become live, we should expect to see them taken much more often. The second cause of instability arises from the knowledge that temptations such as these exist. We become concerned that others might be thinking about taking us for a ride. The fear is not just that we are losing out relative to others, but that they are taking advantage of us and our commitment to fair play. Specifically, they are exploiting our sense of justice. Once this worry takes root in our political culture, it generates a relentless, preemptive Hobbesian logic. Since others will inevitably strike when they can to secure not only their immediate self-interest, but, ultimately, their conception of the good, the only defense is to beat them to the punch. You must get your retaliation in first. Here is an illustration. Some on the political right argue that “political correctness” is a concerted attack on their way of life. The claim is that it amounts to “blanket condemnation of people who don't hew to progressive ideals, in a way that is inimical to free speech and ideological diversity” (Aly & Simpson, 2019, p. 125).24 Couched in terms of stability and a sense of justice, the fear is that rather than competing fairly in the “marketplace of ideas,”25 the opposing side have worked out how to foreclose legitimate debate and smuggle leftist ideals into public discourse as unquestionable presuppositions that are thereby imposed on everyone. Then the gloves come off. Why should you adhere to the rules of draughts when the other side is playing three-dimensional chess? If you really believe that the liberals will not stop until Big Brother is precensoring everything you say, then noxious disruptive tactics such as using hate speech “ironically” to draw opponents into embarrassing overreactions that reveal their nefarious intentions appear justifiable. In an existential conflict, the only acceptable course of action is the one that leads to victory. It would be a fool's errand to try to list every existing or conceivable form of bad disruptive speech and then show how each individual variety enhances one or both of the causes of instability that we have been discussing. In general, we can note that paradigm forms of bad disruptive speech such as fake news, bald-faced political lies, and hate speech have local and global effects that are detrimental to stability as I have defined it here. As we have seen, these behaviors undermine particular norms, such as the norms of authenticity and honesty. More importantly, though, they have the pernicious effect of eating away at a person's belief that their fellow citizens, and especially those citizens who have worldviews very different to their own, possess an effective se
