In Chapter Two of On Liberty, John Stuart Mill makes an argument about the importance of “liberty of thought and discussion” for the progress of society. One argument that he makes is that, even if the established opinion of a society on a particular subject is true, it is still useful to have broad expression of opinions contrary to that (true) established opinion. What are the benefits of airing even false opinions, per Mill? Do you think he is correct? Use an example to substantiate your view.
