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.

The historical resonances are sharp. [Louis] Brandeis is nominated on Jan. 28, 1916. Confirmed on June 1. Waits 125 days between nomination and confirmation, which remains an unbroken record, although Merrick Garland will surpass it in July, if my math is right. Anti-Semitism was definitely not the central reason for the opposition, which tended to focus more on his anti-corporate radicalism, but it was a theme.

Initially the papers said that the fact that Louis Brandeis was picked because he was Jewish. The New York Sun said he's the first Jew ever picked for the bench - a long and bitter fight expected in the Senate over confirmation.

Why I find Louis Brandeis so exciting and inspiring because he's teaching us - good legal writing is not a matter of taste, it's a matter of connection with fellow citizens and of democratic education.

They said, OK, nine [Louis] Brandeis's is too much, but one is OK. So, with friends like that, and so forth. But, yes, the idea that because he was Jewish he would rule a particular way was an ugly undercurrent of the hearings, which resonates with current claims that a judge can't be impartial because of his or her background or ethnicity or race. It's, I guess, a small comfort that in the end the Brandeis vote wasn't close.

That strain of anti-monopoly crusading egalitarianism really runs throughout American history from [Tomas] Jefferson to Woodrow Wilson, that finds its apotheosis in [Louis] Brandeis, continues through the New Deal, but then it sort of peters out in the '60s because progressives in particular become more interested in extending equality to minorities, and women, and other excluded groups, and little more suspicious of these old white guys, often from the south, who were crusaders against monopolies.

When I was in law school I was taught that the great writers were people like [Oliver Wendell] Holmes Jr. and [Benjamin N.] Cardozo. But you go back and read their prose and it's sort of perfumed and very ornate and show-offy. And they're constantly striving for these abstractions that seem archaic nowadays.
