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.

I think even though the court is moving toward trying to translate the Constitution into a digital age, there was that wonderful unanimous decision that Chief Justice Roberts wrote saying you can't search a cellphone on arrest without a warrant.

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.

He's [Louis Brandais] so suspicious of bigness in government as well as business that he mistrusts even really top-down reforms at the state level. The most inspiring part of his legacy to me is his belief in the imperative and duty of self-education on behalf of citizens.

I'd say that [Louis] Brandeis practiced a kind of a "living originalism," to use the title of Jack Balkin's great book. He said you start with the paradigm case, which in the case of the Fourth Amendment was these general warrants or writs of assistance, but you define it at a level of abstraction that you can take it into our age and make it our own.

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.

It's unfortunate that [Louis] Brandeis was not able to translate or abstract his devotion to cultural pluralism and racial equality as he put it for Jews to enslave people and their descendants and to African Americans.
