I went over to see Erich Fromm. I was a big fan of his books.Especially his first one from 1941 called ESCAPE FROM FREEDOM. I also really liked THE ART OF LOVING from 1956. He had a new one coming about. This was in 1969 at the height of the anti war movement. The room was filled with political activists and most of them were very young. You could call them "radicals".
Erich Fromm started to speak. His book was about love and understanding. The young activists started shouting him down. They wanted nothing to do with love or understanding. They wanted "action".

Walter Hopps was a member of the Institute For Policy Studies and a friend of Marcus Raskin and the rest of the people at that "think tank". But I must say I never heard Walter speak one word about politics. Walter let the art works speak for themselves.
I don't remember Walter being "political" at all. He was all about art.
When Walter was Director of The Corcoran Gallery Of Art he did tell me the Nixon adminstration was taping all the phone calls of the people of The Institute For Policty Studies.
