ntration camp, or severely punished. All of these views, views that fundamentally shape people's understanding of the Holocaust, have been believed as though they were self-evident truths. They have been virtual articles of faith, have substituted for knowledge, and have distorted the way in which this period is understood. The absence of attention to the perpetrators is surprising for a host of reasons, only one of which is the existence of a now over-ten-year-long debate about the genesis of the initiation of the Holocaust, which has come to be called by the misnomer the "intentionalist-functionalist"2 debate. For better or worse, this debate has become the organizing debate for much of the scholarship on the Holocaust. The limited character of our knowledge of this period is highlighted by the simple fact the number of people who were perpetrators is unknown. No estimate of any kind exists of the number of people who knowingly contributed to the genocidal killing in some intimate way. Scholars who discuss them, inexplicably, neither attempt such an estimate nor point out that this, a topic of such great significance, is an important gap in our knowledge. Depending on the number and identity of the Germans who contributed to the genocidal slaughter, different sorts of questions, inquiries, and bodies of theory might be appropriate or necessary in order to explain it. One explanation argues for external compulsion: the perpetrators were coerced. They were left, by the threat of punishment, with no choice but to follow orders.
