We often engage in disputes about how events from the past should be remembered. Whether we’ve had an argument with a child, a quarrel with a spouse or a debate about national history, the truth about the past seems to matter a great deal. And yet there are powerful voices in our culture that tell us that we should let go of this interest. The truth about the past cannot be had, the argument goes, and the demand for truth is dangerous. I disagree strenuously. I believe that we have a moral obligation to remember truthfully.
