It is such partly because it will be a prelude to other things that will come after it, the end of this inquiry. To get a mistaken answer to the question of why September 11 was wrong would likely be to store up additional failure. To get a correct answer will help us to deal with the last questions. One will be that of how the subject of moral responsibility for the day of September 11 comes together with the wrong we ourselves have done with multitudes of lives cut short, weak, degraded, respectless or thin. There will also be the question of what we did after September 11, and of what to do now. Why were the killings of September 11 wrong? That is, what is the reason or explanation or ground for the invincible feelings that they were wrong? One of these feelings, as you have heard, was a horror owed to entering into the fear of the victims, people in an extreme situation. Other feelings, lately recalled, had to do with the violation of the agreement between us all that is the fact and practice of natural morality, and with the self-indulgence or worse of inconsis- tency, and with the real truths about human existence at the bottom of morality. Those truths have to do with suffering and the like.
