 There is a broader ethical question to ask about history that goes beyond the professional ethics of the historian to the responsibilities of the public in relation to its own history. The facts of genocide and other crimes against humanity make it clear that there are moral reasons for believing that all of humanity has a moral responsibility to attempt to discover our past with honesty and exactness. In particular, the facts of past horrific actions (genocide, mass repression, slavery, suppression of ethnic minorities, dictatorship) create a moral responsibility for historians and the public alike to uncover the details, causes, and consequences of those actions.
