[Louis] Brandeis is often painted as an acolyte of judicial restraint, or the view that judges should uphold laws whether or not they like them.

[Tomas] Jefferson is more out of fashion, both because of his views on race, where he's properly questioned, that part of his legacy, but also because the libertarian critique of bigness in business and government, the idea that size is a danger is something that's shared on the right when it comes to government and on the left when it comes to corporations, but not both.

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.

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.

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.

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.

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