I was very much influenced by a great book by the scholar Neil Richards called Intellectual Privacy, that [Louis] Brandeis changed his mind on the proper balance between dignity and free speech.

And he [Louis Brandeis] talks to his young acolyte, Horace Kallen, who wrote this beautiful book called Cultural Pluralism, and he comes to believe that by being better Jews, or better members of our ethnic group, we can be better Americans, because America is like an orchestra in which identity is defined by the diversity of perspectives that we bring to the table.

I think the answer has to do with the fact that [Louis D.] Brandeis was a consistent critic of bigness in business and in government.

[Oliver Wendell] Holmes never believed in the truth and morality of the laws he was upholding. He said, "I loathe the thick-fingered clowns we call the people."

Justice Jefferson has a blind spot on race. You know, more than a blind spot. A terrible blemish on his legacy, slavery, for which he's properly excoriated. So, I think [Louis] Brandeis has done this as well.

Louis Brandeis really inspired me to write this book [Louis D. Brandeis: American Prophet]. It was a crazy deadline. The editor said I'd miss the hundredth anniversary unless I pumped the thing out in six months, because I'd been delaying and dilly dallying for so long. So he both inspired me to get up early and write.

That strain of anti-monopoly crusading egalitarianism really runs throughout American history from [Tomas] Jefferson to Woodrow Wilson, that finds its apotheosis in [Louis] Brandeis, continues through the New Deal, but then it sort of peters out in the '60s because progressives in particular become more interested in extending equality to minorities, and women, and other excluded groups, and little more suspicious of these old white guys, often from the south, who were crusaders against monopolies.
