[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.

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.

[Louis] Brandeis, like [Tomas] Jefferson, is an equal opportunity critic of bigness. And he, like Jefferson, sees American history as this incredible clash between small producers, farmers, and small business people on the one hand, and wicked oligarchs and financiers and monopolists on the other.

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.

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.

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.

Before Sept. 11, the idea that Americans would voluntarily agree to live their lives under the gaze of a network of biometric surveillance cameras, peering at them in government buildings, shopping malls, subways and stadiums, would have seemed unthinkable, a dystopian fantasy of a society that had surrendered privacy and anonymity.
