Curiously, while we have a considerable body of literature on the Nazi Holocaust, we do not have a total accounting-at least not until now with the issuance of In addition to the quantitative lacunae, there remains a paucity of theoretical information distinguishing the historical descriptive and the anecdotal accounts. This study of Nazi killings in cold blood is a path-finding effort in political psychology. While Rummel does not claim to give a definitive accounting, his explanation for the numbers reached-and they are high-is compelling. In addition, we now have a correlation of information on the murder of diverse groups: Jews, Gypsies, Poles, Ukranians, and even Germans themselves. It is now possible to fathom the Nazi genocidal poiicies-which were collective and which were selective. Rummel's volume is a clear guide to a murky past. It offers the first systematic effort to ascertain the nature and the extent of the Nazi genocide from the point of view of the perpetrator's aims rather than the victims' consequences. This is not a pretty picture, but it is not a partisan one either. The materials are presented in a clinical as well as a systemic fashion. Rummel has a deep sense of the life-saving instincts of individuals and the life-taking propensities of impersonal state machinery. It is thus, a humanistic effort, one that plumbs the effects of the Nazi war-machine on innocents in order to better understand present conditions. Professionals ranging from social scientists to demographers will find this a quintessential effort at political reconstruction.
