We greeted the 21st century with great anticipation. One year, nine months and eleven days into that new century, that anticipation exploded in sorrow and dread. Fifteen years later, the pall of poison smoke from that day still hangs low over us all. The great mission for the remainder of this century is plain: We must get out from under the control mechanism September 11 has become. We must stop the dominoes from falling. Doing so will require a foray into our deepest selves, a confrontation with what we have allowed to happen.
