"We must also engage, however, in the more difficult task of understanding the sources of such madness. The essence of this tragedy, it seems to me, derives from a fundamental absence of empathy on the part of the attackers: an inability to imagine, or connect with, the humanity and suffering of others. Such a failure of empathy, such numbness to the pain of a child or the desperation of a parent, is not innate; nor, history tells us, is it unique to a particular culture, religion, or ethnicity. It may find expression in a particular brand of violence, and may be channeled by particular demagogues or fanatics. Most often, though, it grows out of a climate of poverty and ignorance, helplessness and despair."
