Hate-racial, tribal, religious, ancestral, national, social, ethical, political, economic, ideological-in itself represents the inexorable defeat of mankind, its absolute defeat. If there is an area in which mankind cannot claim the slightest progress, this surely is it. It does not take much for human beings, collectively or individually, to suddenly one day pit themselves like wild beasts one against the other, their worst instincts laid bare, in a state of deleterious exaltation. One decision, one simple word, and a family or a community will drown in blood or perish in flames. Why is there so much violence, so much hate? How is it conceived, transmitted, fertilized, nurtured? As we face the disquieting, implacable rise of intolerance and fanaticism on more than one continent, it is our duty to expose the danger. By naming it. By confronting it.
