[Louis Brandeis] at the age of 57 decided to become the head of the American Zionist movement was more influential than anyone else in the 20th century in persuading Woodrow Wilson to recognize a Jewish homeland in Palestine.

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.

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.

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.

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.

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.
