I shared my perspective about "9/11" on September 12, 2004, before a church congregation.  I wanted to make note of three particular ideas because I could already see them fading from popular thought.  Immediately following the terrorist attacks in 2001, it was easy to infer a consensus around these notions: evil exists, people are intrinsically valuable, and truth is not relative.  Now, 7 years after that speech and 10 years after the attacks, it's clear that I was right to worry.  We don't remember what we believed about those ideas in September 2001, and we can't satisfactorily explain why.
