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.

Initially the papers said that the fact that Louis Brandeis was picked because he was Jewish. The New York Sun said he's the first Jew ever picked for the bench - a long and bitter fight expected in the Senate over confirmation.

Louis Brandeis never had the opportunity - or he never sought the opportunity I should say - to work closely with African American lawyers. He was also a Southern Democrat, you know, at a time when both parties were supportive of segregation.

[Louis] Brandeis had a very distinctive vision of political economy that he persuaded Woodrow Wilson to adopt in the 1912 election and that he largely enacted from the bench.

I don't think he would have had any trouble answering Justice Sonia Sotomayor's excellent challenge in a case involving GPS surveillance. She said we need an alternative to this whole way of thinking about the privacy now which says that when you give data to a third party, you have no expectations of privacy. And [Louis] Brandeis would have said nonsense, of course you have expectations of privacy because it's intellectual privacy that has to be protected. That's my attempt to channel him on some of those privacy questions.

But as I wrote the book [Louis D. Brandeis: American Prophet], I tried to write it as clearly and directly and passionately as possible just thinking of communicating to readers who might want to learn about this great thinker and be inspired by him as I was.

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.
