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.

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 [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.

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.

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] believes in natural rights of speech and liberty and the right to pursue happiness.

And he [Louis Brandeis] talks to his young acolyte, Horace Kallen, who wrote this beautiful book called Cultural Pluralism, and he comes to believe that by being better Jews, or better members of our ethnic group, we can be better Americans, because America is like an orchestra in which identity is defined by the diversity of perspectives that we bring to the table.
