I think [Louis] Brandeis challenges all of the current justices. As he said, "If we would guide by the light of reason, we must let our minds be bold." You have to take the values that the framers were concerned about and translate them into this new age.

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.

[Louis Brandeis] insisted on the necessity of public reason, which he thought could only be achieved if all of us just take the time to inform ourselves about the best arguments on all sides of questions so that we can make up our own minds.

[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.

Do you think Bernie Sanders, for example, is citing Theodore Roosevelt as the progenitor of his critique of the banks when actually Roosevelt wanted to keep the banks together and regulate them.

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

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.
