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.

Why I find Louis Brandeis so exciting and inspiring because he's teaching us - good legal writing is not a matter of taste, it's a matter of connection with fellow citizens and of democratic education.

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'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.

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.

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.

Louis Brandeis started off by embracing the Theodore Roosevelt notion that hyphenated Americanism was unpatriotic. You couldn't have dual loyalties. But then he thinks and he reads and he becomes the head of the American Zionist movement after having previously been a secular Jew in this amazing intellectual evolution.
