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.

[Louis] Brandeis is writing directly to us. His clear voice comes through a century and he's speaking to us and he's galvanizing us and he's persuading us. And that's why I love to read the prose.

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.

William Howard Taft, who he embarrassed in these congressional hearings, attacks him as an emotionalist and a socialist and a cosmopolitan in terms that kind of have an anti-Semitic overtone. And even the pro-Brandeis press supported him in terms that really seem creepy today. There's this piece from Life magazine. It says, "Mr. Brandeis is a Jew. And until now there's never been a Jew on the Supreme Court. Perhaps it's time we have one."

I think [Louis] Brandeis challenges all of the current justices. As he said, "If we would guide by the light of reason, we must let our minds be bold." You have to take the values that the framers were concerned about and translate them into this new age.

Whenever I felt tempted to, I don’t know, watch cat videos or bad Netflix TV instead of writing this Brandeis biography, I thought of his stern but kindly visage and buckled down and wrote the damn thing, because there’s so much information out there, and these are such anxious times in democracy, such unreasonable times.
