The 19 talks at an August 1990 international colloquium held at the United Nations are reprinted a decade later because the issues addressed are still as relevant and often more arms reduction and the nuclear threat, medicine and health care, ethics and human rights, and ecology and the environment. Among the speakers are Oscar Arias Sanchez, Norman Cousins, Linus Pauling, Pearl Bailey, Jane Goodall, and Dennis Weaver. There is no index. Annotation c. Book News, Inc., Portland, OR (booknews.com)
