Point is, Mill lived in an era where dissemination of information was barely at a steam-engine equivalent, whereas now we've got automated opinion-generating rocket systems in orbit ready to barrage millions of info missiles at any online discussion at any point in any language within 300 nanoseconds.
I started reading through On Liberty recently and I was surprised by how topical it was. This discussion doesn't seem to have changed much over the past 150 years. Mill spends a long time addressing arguments for censorship that I still see used today.
A lot is lost when a book-length discussion is reduced to a single sentence. In his work, there's a very thorough discussion of why this liberty is essential. I don't like how the grandparent used the quote so flippantly. Without the supporting context, it's a baseless statement that encourages low-quality discussion.
One of things Mill did really well is that he thoroughly described his opponents' position before arguing why it was incorrect. You haven't done that, which is why it's unclear what part of his argument is invalidated by improvements in communications.
Here's an excerpt of an argument by Marcuse (by no means the only one to argue against Mill, in fact there are philosophers who question the entire justification for free speech, and I think they have a more interesting point, though they don't directly address Mill):
>Now in recalling John Stuart Mill's passage, I drew attention to the premise hidden in this assumption: free and equal discussion can fulfill the function attributed to it only if it is rational expression and development of independent thinking, free from indoctrination, manipulation, extraneous authority. The notion of pluralism and countervailing powers is no substitute for this requirement. One might in theory construct a state in which a multitude of different pressures, interests, and authorities balance each other out and result in a truly general and rational interest. However, such a construction badly fits a society in which powers are and remain unequal and even increase their unequal weight when they run their own course. It fits even worse when the variety of pressures unifies and coagulates into an overwhelming whole, integrating the particular countervailing powers by virtue of an increasing standard of living and an increasing concentration of power.
> I don't like how the grandparent used the quote so flippantly. Without the supporting context, it's a baseless statement that encourages low-quality discussion.
The context was someone saying they have no problem with users flagging stories, as long as it's not the mods. I disagree, and I might just as well have said "personally, I don't like it either (when some of the hoi polloi take it on them to decide what the rest should discuss, insted of using the "hide" feature)". Instead I said it with a quote.
That doesn't "encourage" ignoring that context, a non-sequitur slogan like "new realities need new quotes", and equating any verbal or written statement, even lies or auto-generated spam, with persons holding an opinion.
For what it's worth, I had upvoted you. The shallowness of the discussion wasn't something you started, and I'm not sure you really had a responsibility to end it. I just wanted to see us do better as a community.
New realities need new quotes.
