The last work of Rabbi Emeritus, Dr. Jossef Kratzenstein, discusses man's inhumanity to man. Rabbi Kratzenstein's work focuses on the barbarism of humankind which has been prevalent throughout the ages. Dr. Kratzenstein wrote: "Civilized cannibals constitute a clan of their own. They murder creatures of their own kind by the tens of millions without ever eating one of them. A most interesting phenomenon, indeed. There must be a very special kind of "hunger" which drives civilized cannibals to such actions." If the "hunger" still exists, then is it possible for a HOLOCAUST to occur again? The seeds are now being planted, but we must never forget. Critics state the following: "Rabbi Kratzenstein's essay, "WHENCE COMES EVIL," deals with the massive problem of human hate..... The human layers which scantily cover man's brutality are thin & frail (Kratzenstein); to nurture those fragile human layers is our spiritual destiny & redemption."--Patricia Drury, Associate Professor of History, Emeritus, Delta College. "(Rabbi Kratzenstein's) work is full of perceptive insights, shrewd observations, & judicious arguments. (His book) should be read by every Christian in this country, not to mention every Jew."--Nahum M. Sarna, Former Consultant/General Editor, The Jewish Publication Society.Kratzenstein, Jossef is the author of 'Whence Comes Evil? : An Essay on Man in Action', published 1991 under ISBN 9780963192905 and ISBN 0963192906.
