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.

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.

[Louis Brandeis] at the age of 57 decided to become the head of the American Zionist movement was more influential than anyone else in the 20th century in persuading Woodrow Wilson to recognize a Jewish homeland in Palestine.

Privacy is not for the passive.

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.

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

For [Louis] Brandeis, you know, ethnicity and background are much less important than facts and reason. And he believes that far from wanting to efface our diversity of perspectives, we have to embrace it because that makes us more American, not less. In that sense, he's incredibly modern in an age of cultural pluralism. And it is disappointing for just the reasons you say that not everyone has embraced his pluralistic vision.
