Lewis Thomas

Pathologist, professor, and essayist Lewis Thomas. As an essayist he takes a philosophical look at biomedicine. His books include the "The Lives of a Cell," and "The Medusa and the Snail," which were both best sellers. But he began writing for only the medical community with his 1974 column in the "New England Journal of Medicine." Terry talks with him from his hospital room, where Thomas is recovering from several ailments. He has a new book, "The Fragile Species," (published by Scribner's)
