The murders at Charlie Hedbo and their aftermath raised the issue of freedom of expression in a dramatic and terrible manner. In response to these deaths, there was an outpouring of support for this basic freedom and, somewhat ironically, a crackdown on some people expressing their views.
This situation raises two rather important issues. The first is the matter of determining the worst thing that a person should express. The second is the matter of determining the worst thing that a person should be allowed to express. While these might seem to be the same issue, they are not. The reason for this is that there is a distinction between what a person should do and what is morally permissible to prevent a person from doing. The main focus will be on using the coercive power of the state in this role.
As an illustration of the distinction, consider the example of a person lying to his girlfriend about running strikes all day in the video game Destiny when he was supposed to be doing yard work. It seems reasonable to think that he should not lie to her (although exceptions are easy to imagine). However, it also seems reasonable to think that the police should not be sent to coerce him into telling her the truth. So, he should not lie to her about playing the game but he should be allowed to do so by the state (that is, it should not use its police powers to stop him).
This view can be disputed and there are those who argue in favor of complete freedom from the state (anarchists) and those who argue that the state should control every aspect of life (totalitarians). However, the idea that that there are some matters that are not the business of the state seems to be an intuitively plausible position—at least in democratic states such as the United States. What follows will rest on this assumption and the challenge will be to sort out these two issues.
One rather plausible and appealing approach is to take a utilitarian stance on the matter and accept the principle of harm as the foundation for determining the worst thing that a person should express and also the worst thing that a person should be allowed to express. The basic idea behind this is that the right of free expression is bounded by the stock liberal right of others not to be harmed in their life, liberty and property without due justification.
In the case of the worst thing that a person should express, I am speaking in the context of morality. There are, of course, non-moral meanings of “should.” To use the most obvious example, there is the “pragmatic should”: what a person should or should not do in regards to advancing his practical self-interest. For example, a person should not tell her boss what she really thinks of him if doing so would cost her the job she desperately needs. To use another example, there is also the “should of etiquette”: what a person should do or not do in order to follow the social norms. For example, a person should not go without pants at a formal wedding, even to express his opposition to the tyranny of pants.
Returning to the matter of morality, it seems reasonable to go with the stock approach of weighing the harm the expression generates against the right of free expression (assuming there is such a right). Obviously enough, there is not an exact formula for calculating the worst thing a person should express and this will vary according to the circumstances. For example, the worst thing one should express to a young child would presumably be different from the worst thing one should express to adult. In terms of the harms, these would include the obvious things such as offending the person, scaring her, insulting her, and so on for the various harms that can be inflicted by mere expression.
While I do not believe that people have a right not to be offended, people do seem to have a right not to be unjustly harmed by other people expressing themselves. To use an obvious example, men should not catcall women who do not want to be subject to this verbal harassment. This sort of behavior certainly offends, upsets and even scares many women and the men’s right to free expression does not give them a moral pass that exempts them from what they should or should not do.
To use another example, people should not intentionally and willfully insult another person’s deeply held beliefs simply for the sake of insulting or provoking the person. While the person does have the right to mock the belief of another, his right of expression is not a moral free pass to be abusive.
As a final example, people should not engage in trolling. While a person does have the right to express his views so as to troll others, this is clearly wrong. Trolling is, by definition, done with malice and contributes nothing of value to the conversation. As such, it should not be done.
It is rather important to note that while I have claimed that people should not unjustly harm others by expressing themselves, I have not made any claims about whether or not people should or should not be allowed to express themselves in these ways. It is to this that I now turn.
If the principle of harm is a reasonable principle (which can be debated), then a plausible approach would be to use it to sketch out some boundaries. The first rough boundary was just discussed: this is the boundary between what people should express and what people should (morally) not. The second rough boundary begins at the point where other people should be allowed to prevent a person from expressing himself and ends just before the point at which the state has the moral right to use its coercive power to prevent expression.
This area is the domain of interactions between people that does not fall under the authority of the state, yet still permits people to be prevented from expressing their views. To use an obvious example, the workplace is such a domain in which people can be justly prevented from expressing their views without the state being involved. To use a specific example, the administrators of my university have the right to prevent me from expressing certain things—even if doing so would not fall under the domain of the state. To use another example, a group of friends would have the right, among themselves, to ban someone from their group for saying racist, mean and spiteful things to one of their number. As a final example, a blog administrator would have the right to ban a troll from her site, even though the troll should not be subject to the coercive power of the state.
The third boundary is the point at which the state can justly use its coercive power to prevent a person from engaging in expression. As with the other boundaries, this would be set (roughly) by the degree of harm that the expression would cause others. There are many easy and obvious example where the state would act rightly in imposing on a person: threats of murder, damaging slander, incitements to violence against the innocent, and similar such unquestionably harmful expressions.
Matters do, of course, get complicated rather quickly. Consider, for example, a person who does not call for the murder of cartoonists who mock Muhammad but tweets his approval when they are killed. While this would certainly seem to be something a person should not do (though this could be debated), it is not clear that it crosses the boundary that would allow the state to justly prevent the person from expressing this view. If the approval does not create sufficient harm, then it would seem to not warrant coercive action against the person by the state.
As another example, consider the expression of racist views via social media. While people should not say such things (and would be justly subject to the consequences), as long as they do not engage in actual threats, then it would seem that the state does not have the right to silence the person. This is because the expression of racist views (without threats) would not seem to generate enough harm to warrant state coercion. Naturally, it could justify action on the part of the person’s employer, friends and associates: he might be fired and shunned.
As a third example, consider a person who mocks the dominant or even official religion of the state. While the rulers of such states usually think they have the right to silence such an infidel, it is not clear that this would create enough unjust harm to warrant silencing the person. Being an American, I think that it would not—but I believe in both freedom of religion and the freedom to mock religion. There is, of course, the matter of the concern that such mockery would provoke others to harm the mocker, thus warranting the state to stop the person—for her own protection. However, the fact that people will act wrongly in response to expressions would not seem to warrant coercing the person into silence.
In general, I favor erring on the side of freedom: unless the state can show that silencing expression is needed to prevent a real and unjust harm, the state does not have the moral right to silence expression.
I have merely sketched out a general outline of this matter and have presented three rough boundaries in regards to what people should say and what they should be allowed to say. Much more work would be needed to develop a full and proper account.
