This book discusses ethical behavior through the genocidal stages of the Holocaust. Paul E. Wilson first looks at the antisemitism in Germany and Europe beginning in the decades preceding the Nazis reign of terror, and goes on to discuss the ethical decisions made in the initial stages that moved society toward genocide. The author maintains that the stages of genocide represent subtle changes that can be happening within a society in response to the moral choices made by actors.  By giving attention to the stages of genocide in the Holocaust, this book contributes to the overall understanding of how the Holocaust was possible, and encourages the moral community to join the watch for the development of genocide in the modern world.
