Mr. Kinsley begins: "The talk-show host Larry King says that when the subject is abortion, the host never learns anything new. One goal of today's program is to prove him wrong." Whether that goal was achieved is debatable, but it certainly is unusual to hear someone who says, as Mr. Tribe does, "I think it's awfully hard to deny that forcing a woman to remain pregnant against her will, to make a use of her body that she has come to find profoundly offensive,... is a deep assault on her freedom and, indeed, on her equality," also say, "The fetus surely is alive. There's no doubt that it's a member of the human species. Its very helplessness cries out for protection." An unusually thoughtful and thought-provoking discussion of a topic that often incites to a trading of slogans.
