The theme of this rich and highly focused volume is Polish perceptions of Jews and Jewish perceptions of Poles from the Middle Ages to the present. Essays by Leszek Kolakowski and Wladyslaw Bartoszewski set the parameters of the debate. Contributors analyse sources ranging from Yiddish folk-songs to Hebrew, Yiddish, and Polish literature to Polish plays, and the discussions range over the entire period. Norman Davies writes on ethnic diversity in twentieth-century Poland, and other essays deal with related political aspects. There is also an important exchange between Stanislaus Blejwas and Shmuel Krakowski entitled 'Polemic as History'.
