Lenore: It is naive to think that historical explanations can be objective. In evaluating evidence, historians are always influenced by their national, political, and class loyalties. Victor: Still, the very fact that cases of biased thinking have been detected and sources of bias identified shows that there are people who can maintain objectivity. Victor's response does not succeed as a rebuttal of Lenore's argument because his response ['overlooks the possibility that those who detect and identify bias are themselves biased in some way', "displays the same kind of biased thinking as that against which Lenore's argument is directed", 'does not consider sources of bias in historical explanation other than those that are due to national, political, and class loyalties.', 'fails to provide examples of cases in which biased thinking has been detected and the source of that bias identified']
