Collective memory

Is it important, or even possible, for people to remember the events of Sept. 11 as they happened? Or is it more important for a society to concentrate on collective memory?

At the same time it vividly evokes the almost preposterous horror of war itself, which Mr. [Walid] Raad experiences both first hand and from a distance, and has evoked as semifictional collective memory.

The shift in the collective memory is also taking place in local schools, where some teachers still refuse to teach lessons on 1921.
