A very useful book, in that the author provides a cogent summary of 19th and 20th century anti-semitic trends, and how they developed (and metastasized). Less interesting is a psychological discussion of how anti-semitism can evolve, though this is largely because I don't have a deep background in psychology. The book was apparently written in November, 1944 (it was published in 1945), shortly before some of the major horrors of the Holocaust were revealed. As it is, Parkes is prescient in discussing how the "Jewish National Home," later Israel, would become a focus of post-war discussion. Alas, this book is still somewhat timely. ( )
