September 11, 2011, marks the ten-year anniversary of the terrorist attacks on the World Trade Center and the Pentagon.

Ten years have passed, and there is still much to grieve. There are the lives that were lost that terrifying and tragic day: the 2,977 victims in the towers and the Pentagon and on the planes; and the 415 law enforcement officers and firefighters killed, public workers who were justly celebrated at the time as heroes—an impulse we would do well to remember today, as their counterparts are pilloried as pension gluttons and public service is casually denigrated as government bloat.

Now, we want to know how the attacks may have affected your views and perspectives. Did the attacks alter your way of seeing the world? Shake any core beliefs?
