Magnum, true to pleasure.

Robert Zimmer has left us.

At the age of 75, a young man Richard.

Richard Epstein is here to help me understand the significance of Mr. Zimmer's 15 years as president of the University of Chicago,

When it becomes president some years later, what happens is there's a free speech problem on campus.

And it turns out this is a problem for which the University of Chicago is uniquely situated by late colleague and dear friend Harry Calvin.

Back in the 1960s, issued what was called the Calvin report, trying to talk about the appropriate lines for free speech and for protest.

Because at that particular time, Stolton, Lyndon and a bunch of other people started to occupy the administration building.

And it became very difficult to figure out what the line was between legitimate speech on the one hand and this ruptured behavior on the other.

I can recall attending election given by Edward Banfield, and there's a bunch of people, persons, or who say,

racist Banfield, you can't hide, you charge, you're a genocide.
