John Stuart Mill’s On Liberty: The Importance of Individual Liberty in a Society
1. Introduction
John Stuart Mill's On Liberty is one of the most important works of political and social philosophy ever written. In it, Mill argues for the importance of individual liberty in a society and outlines the conditions under which that liberty can be limited.
Mill begins by distinguishing between two types of social restraint: those that are self-imposed, and those that are externally imposed. He argues that the former type of restraint is generally beneficial, as it allows individuals to pursue their own goals and develop their own talents. The latter type of restraint, however, is generally harmful, as it prevents individuals from expressing their opinions and engaging in activities that would be beneficial to them.
Mill then goes on to argue that the only legitimate reason for limiting someone's liberty is to prevent them from harming others. Any other reason, such as the prevention of harm to oneself or the promotion of the "common good," is unjustifiable.
Mill concludes by arguing that even when the harm principle is satisfied, there should still be a presumption in favor of liberty. This is because, in Mill's view, the free expression of opinions and the pursuit of one's own goals are necessary for individual development and progress.
2. Opinions and Truth
One of the central claims of On Liberty is that "opinions are not sus- tained by truth alone" (Mill 1859, p. 46). In other words, individuals can hold false beliefs without necessarily being irrational or misguided. This claim has important implications for how we ought to treat those who hold different opinions from us.
If opinions are not always based on truth, then it follows that we cannot expect people to always agree with us. It also follows that we should not try to compel people to agree with us through either legal force or social pressure. Instead, we should allow them to express their opinions freely, even if we believe those opinions to be false.
The reason for this is twofold. First, as Mill points out, "it is impossible to judge of [an opinion] until it has been expressed" (Mill 1859, p. 47). In other words, we cannot know whether an opinion is true or false until it has been expressed and subjected to scrutiny. Second, even if an opinion is false, it may still have some merit. As Mill explains: "[E]ven if an opinion is true, if it is not fully, accurately, and carefully expressed…it may be harmful" (Mill 1859, p. 47). Thus, even false opinions can be useful if they are expressed clearly and critically examined.
3. Individuality and Development
Another central claim of On Liberty is that "the growth of individual- ity" is essential for the development of society as a whole (Mill 1859, p. 51). This claim has important implications for how we ought to treat those who hold different opinions from us.
As Mill explains: "[I]ndividuality…is one of the elements which society can only learn to tolerate, and not to produce" (Mill 1859, p. 51). In other words, society cannot force individuals to be unique or different from one another. Instead, it can only learn to accept the fact that people are different.
This is important because, as Mill points out, "[i]ndividuality is a necessary condition of progress" (Mill 1859, p. 51). That is, without diversity of opinion and perspective, society will stagnate and fail to progress.
4. The Tyranny of the Majority
One of the most important arguments in On Liberty is Mill's argument against the tyranny of the majority. This is the claim that a majority of people can use their power to restrict the liberties of minorities, even when those minorities are not harming anyone.
As Mill explains: "[T]he fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd; indeed in view of the silliness of so much that has been believed, it is rather a presumption against it" (Mill 1859, p. 52). In other words, just because a majority of people believe something does not make it true. And even if something is true, it does not mean that a majority of people should believe it.
The reason for this is that, as Mill points out, "[t]o compel a man to hold opinions he does not believe is…to violate that principle of intellectual liberty which claims for every human being prev- ilege to form and hold whatever opinions he chooses" (Mill 1859, p. 54). In other words, forcing someone to believe something they do not want to believe is an infringement on their liberty.
5. Freedom of Speech and Expression
One of the most important applications of Mill's arguments is to the question of freedom of speech and expression. This is the right to express one's opinions freely without fear of retribution or censorship.
As Mill explains: "If all mankind minus one were of one opinion, mankind would be no more justified in silencing that one person than he…would be justified in silencing mankind" (Mill 1859, p. 55). In other words, even if everyone else in the world agrees with each other, they have no right to silence someone who disagrees with them.
The reason for this is that, as Mill points out, "[t]he peculiar evil of silenc- ing the expression of an opinion is…that it deprives the human race…of progress" (Mill 1859, p. 56). In other words, preventing people from expressing their opinions hinders social progress by preventing new and better ideas from being voiced and discussed.
6. Limits to Liberty
Although Mill argues strongly in favor of individual liberty, he recognizes that there are some circumstances in which that liberty can legitimately be limited. The most important of these is when someone's actions pose a direct threat to the safety or well-being of others. As Mill explains: "[T]he only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others" (Mill 1859, p. 59).
This "harm principle" is the basis for many of the laws that exist in society today. For example, laws against murder and assault exist to protect people from being harmed by others. Similarly, laws against fraud and theft exist to protect people from being harmed financially.
7. Conclusion
In On Liberty, John Stuart Mill argues strongly in favor of individual liberty. He makes a compelling case that the only legitimate reason for limiting someone's liberty is to prevent them from harming others. And he points out that even when the harm principle is satisfied, there should still be a presumption in favor of liberty.
Mill's arguments are as relevant today as they were when they were first written. In an age when more and more people are calling for the restriction of speech and expression, Mill's arguments provide a much-needed defense of the importance of free speech and open debate.
