It can sound trite if you just say citizens need to be educated for democracy to work, but for him it wasn't trite. It was really this strenuous challenge to citizens to use their moments of leisure, which he defined as time away from work, to collect the facts that were necessary for full democratic participation.

Unlike [Woodrow] Wilson, Louis Brandeis did not support the segregation of the federal government. He was personally courteous to African Americans. He advised them and advised the head of Howard University to create a good law school. And that inspired Charles Hamilton Houston and Thurgood Marshall in their path-breaking work on behalf of desegregation.

The tyranny of Harvard and Yale is another thing that transcends this problem of the set point. But what's so striking about [Louis] Brandeis is he had this vision of cultural pluralism that completely gave the lie to the idea that there was any inconsistency between being Jewish or being a woman or being African American and being fully American.

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.

[Louis] Brandeis improves the prose. He simplifies it and perfects the balance of the sentence so it becomes even more memorable and aphoristic.

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.
