The column discusses this Rockwell painting, which we often use in discussing free speech controversies.

Here is the column:

Eighty years ago, the U.S. government launched a war bond campaign featuring a painting by artist Norman Rockwell in the struggle against the authoritarian threat from Europe. The picture they chose was Rockwell's Freedom of Speech depicting a man rising to speak his mind at a local council meeting in Vermont. The image rallied the nation around what Louis Brandeis called our "indispensable right."

Now, that very right is again under attack from another European government, which is claiming the right to censor what Americans are allowed to say about politics, science and other subjects. Indeed, the threat from the European Union may succeed in curtailing American freedom to an extent that the Axis powers could not have imagined. They may win, and our leaders have not said a thing yet about it.

In my book "The Indispensable Right: Free Speech in an Age of Rage," I discuss the inspiration for Rockwell's painting: a young selectman in Vermont named James "Buddy" Edgerton. The descendent of a Revolutionary War hero, Edgerton stood up as the lone dissenter to a plan to build a new schoolhouse over the lack of funding for such construction.

For Rockwell, the scene was a riveting example of how one man in this country can stand alone and be heard despite overwhelming opposition to his views. It was, for Rockwell (and for many of us), the quintessential American moment.

In the 1940s, people like Edgerton had to travel to small board meetings or public spaces to speak their mind. Today, the vast majority of political speech occurs over the Internet and specifically social media. That is why the internet is the single greatest advancement for free speech since the printing press.
