Andie N knew Posner. I knew Tigar, from an extreme distance, as a friend of a friend I did know close up at UCB just after the Free Speech Movement. BTW, Tigar's father was a machinist and Tigar was student body president of one of my high schools, and graduated before I arrived. Tigar was denied a clerkship under Douglas, on rumors he was communist, and worked on the defence team for Terry Nicols in the Oklahoma City bombing.
Reading Tigar today, I could hear the sound of that old time religion preached at UCB back in the day.
I also think if anybody bothers to read the two posts on Strauss, and then read the Tigar article, you will hear the great debate in a multiple way. Me in much less eloquant ways against Strauss, Tigar in command of the word against Posner.
Thinking on it, I have to wonder if Posner might be an affectionado of Strauss or a related political philosopher...
Here is Tigar:
