William Howard Taft, who he embarrassed in these congressional hearings, attacks him as an emotionalist and a socialist and a cosmopolitan in terms that kind of have an anti-Semitic overtone. And even the pro-Brandeis press supported him in terms that really seem creepy today. There's this piece from Life magazine. It says, "Mr. Brandeis is a Jew. And until now there's never been a Jew on the Supreme Court. Perhaps it's time we have one."

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.

He [Louis Brandeis] would have not had any patience with that great debate which you're right to kind of signal between Justice Scalia and Justice Alito about do you need a physical trespass into the home or onto the carriage in order to trigger the values of the Fourth Amendment.

I was very much influenced by a great book by the scholar Neil Richards called Intellectual Privacy, that [Louis] Brandeis changed his mind on the proper balance between dignity and free speech.

Basically [Louise] Brandeis was a Jeffersonian. And you say the timing is great, and it is in a lot of senses, except not for [Tomas] Jefferson, because this is a Hamiltonian moment, and he's the rock star of the minute with a great musical.

We need to protect the same amount of cognitive liberty in an age where you can invade people's thoughts without physically intruding into their homes than you did at the time of the framing.

Louis Brandeis actually changes his mind about women's suffrage because he works with these brilliant women in the women's suffrage movement like Josephine Goldmark, his sister-in-law, where he writes a Brandeis brief which convinced the court to uphold maximum hour laws for women by collecting all these facts and empirical evidence.
