Psychology professor Lt. Col. Dave Grossman talks about his new book "On Killing: The Psychological Cost of Learning to Kill in War and Society". He maintains that it is inherent in us to resist killing our own species and that research has proven that many soldiers engaged in face-to-face combat found it difficult to kill. Soldiers can be trained however, to overcome that resistance. Some veterans are still plagued with guilt about taking another man's life, but this guilt can be eased if they are assured that what they did was right. Addressing the rise in civilian murders, he believes that part of the reason is that children are becoming desensitized to violence because they are associating the bombardment of graphic images by the media with pleasure. (Originally aired March 1996).

Pulitzer Prize-winning biographer and historian Doris Kearns Goodwin talks about her new book "Wait Till Next Year".

She believes the 50s were the glory days of baseball and she tells a charming anecdote about getting the autograph of her hero, Jackie Robinson. (Originally aired January 1998)

Political pundit Peter Beinart believes a return to the historical roots of liberalism will be the only political movement to save the U.S. and its place as a positive force in the world.

Law Professor Alan Young has ruffled some feathers in the legal profession with his book "Justice Defiled: Perverts, Potheads, Serial Killers and Lawyers". He believes that drug use should be decriminalized, his argument being that too much money and court time is being used in the prosecution of drug users. He believes that if recreational drug use, including heroin and cocaine, was legal, the majority of people would use them responsibly. However, he concedes that some would not and possibly more users would become addicted. He also believes prostitution should be decriminalized. He takes a swing at his own profession, which he says is rife with hypocrisy and greed, and at the use of plea bargaining, which he sees as a sham, used only by lawyers to ditch unprofitable cases quickly.

Patchen Barss is the author of "The Erotic Engine". Barss contends that the main driving force behind the evolution of the internet, has been the pornography industry.
