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.

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.

[Louis] Brandeis, like [Tomas] Jefferson, is an equal opportunity critic of bigness. And he, like Jefferson, sees American history as this incredible clash between small producers, farmers, and small business people on the one hand, and wicked oligarchs and financiers and monopolists on the other.

We shouldn't let the Republicans off the hook. Theodore Roosevelt, we learned from Jeff Cowan's new book, was just as bad as certainly [Louis] Brandeis was, or many Democrats were on the question of segregation.

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

What is so inspiring about [Louis] Brandeis's writing is he saw it as a tool for democratic education. He would say things like the opinion is now convincing, now can we make it more instructive, after he'd gone through ten drafts.

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.
