Our guests are the former Anglican Bishop of Scotland (who lost his faith), the founder of the Jesus Seminar and two other “men of the cloth.” In this vivid 2002 discussion these four present and former clergymen trade their doubts and certainties – and their historical hypotheses about the origins and present credibility of the master narrative and modern meaning of Christianity.

Veteran members of the American Federation of Radio and Television Artists go to town with a number of classic radio scripts rendering old time radio new again. This show is from 2007.

Our guests are Susan Clancy, psychologist from Harvard, and Paul Kurtz, founder of the Committee For The Investigation Of The Paranormal (PSICOP). The great modern myth of alien abduction is traced, examined, evaluated and interpreted by these two expert investigators who have many strange stories to tell.

Timothy Ferris, a great science journalist and astrophysics specialist, matches Carl Sagan – who was his friend and colleague – in his capacity to make the ultimate sing and “zing.” A very good time was had by all on this particular night in 2007.

Historian Deborah Dwork and her colleague (an architectural scholar) focus in on the 20th century history of Auschwitz. They probe who was “processed” there, how, and (the unanswerable question) why.

The remarkable actor Sir Peter Ustinov and friends visit. The “friends” are both of Ustinov’s invention, as he pulled off a brilliant improvisation with us in 1998. A high comedic moment in the history of the program.

From the “sexual communism” of the Oneida Community to the Hippie communities of the 60s and 70s, and continuing with the present-day Amish and other Anabaptists – there has been a whole lot of “perfectionism” going on. The full historical account is developed in this conversation from 1997.

A full conversation from 2008 in which one of the country’s best and most unapologetic social critics tells it the way it really is – and the way it must be changed if we are to survive as a competent nation.
