Journalist MICHAEL KAUFMAN. His new book, Mad Dreams, Saving Graces - Poland: A Nation in Conspiracy, charts the rise, fall and resurrection of the democratic movement in Poland. Leading this drive has been Solidarity, the shipworkers' union headed by Lech Walesa. But Kaufman also traces the hidden spiritual undercurrents in Polish history and culture and that make this quest toward self-definition considerably more complex. Kauffman served as Warsaw bureau chief for The New York Times from 1984 to 1987. He has also been bureau chief for the Times in Nairobi, New Delhi and Ottawa.
