> Scientific and political beliefs often do not stand the test of time, but is it fair to blame the people of past eras for their misjudgements using the values of today? the problem with this reasoning is that it assumes or tries to imply that people "back then" all held such backwards beliefs, which far too often is not the case. For instance, see how Morse's diatribes on slavery and racism are presented - but the state he was born and operated in already abolished slavery about a decade before his birth.
