"Assassins of Memory" is a passionate and painstaking look at one of the more curious realities of recent French cultural life: the prominence accorded to the phenomenon of "revisionism". An attempt on the part of a tiny group of fanatics, often masquerading as scholars and researchers, to deny the existence of the gas chambers and horrors of Hitler's genocidal policies, revisionism is quietly gaining adherents. The movement has been most visible in France in the past decade, particularly because of the trial of Klaus Barbie and the writings of Robert Faurisson. Revisionists are more prevalent and are gaining followers in other countries, including the United States, where the "Journal of Historical Review" is devoted to revisionist thought and where a current presidential candidate has expressed what could be described as revisionist ideas. "Assassins of Memory" exposes revisionism for the deeply perverse enterprise it is, laying bare the mechanisms of lies and manipulations on which it is sustained. More than this, it asks searching questions about the underlying causes of revisionism and its influences and diffusion in France and elsewhere. The book is particularly illuminating on the role the American linguist Noam Chomsky has played as writer of a preface to one of the movement's more influential tracts. Underlying Vidal-Naquet's argument is the question: is it acceptable for people to spread evil ideas, or should they be suppressed?
