Could I comment on that? I wouldn't myself phrase the debate quite so clearly in terms of rights and duties. That's just a personal preference. That's not the way I personally would approach it, but I guess we're here, to some extent, to try to understand why free speech is important and what its importance is.
Now, there are any number of accounts of the importance of free speech. One claim -- it's been alluded to already -- is the claim: well, free speech, Mill seems to think, will deliver truth in the free marketplace of ideas. So he seems to think the world is like a huge seminar room: everybody says the thing that they want to say and sooner or later, truth comes out.
Now, that defence of free speech strikes me as very, very limited indeed, partly because there are significant power interests in modern democracies, so it just isn't the case that my speech is heard as well as the speech of people who own vast areas of the press, also because it isn't clear anyway that freedom of speech will deliver truth even in a free marketplace of ideas, where there's rough equality of power.
I cited in the evidence I gave a book by Bernard Williams called "Truth and Truthfulness", in which he says: if you look at those institutions which are most closely associated with trying to discover truth, like courts of law and universities, what you'll find is that there are very considerable restrictions on freedom of speech. I don't, in my seminar, allow my students to heckle one another or to shout offensive remarks at one another. That's not legitimate.
So in fact, the pursuit of truth is something which calls for restriction of free speech just as much as it calls for free speech. So that argument seems to me slack.
There's an argument in terms of autonomy, which we've mentioned already, and then an argument in terms of democracy, which has also been touched upon, but what we need to think about here, if we're arguing or trying to consider the importance of free speech, is: what is free speech for? Why do people want it? I think there are different answers to that, depending on whether you're looking at the individual or the press, press freedom as opposed to individual freedom.
