With all the craziness going on in the world, such as the evil-doers as our leader likes to call them, we ask "Why do people do such things?" This is at least partly in the realm of sociology, with which I usually associate myself.
Now that the tsunami has come along, we ask, "Why does Mother Nature do such things to us." Of course Mother Nature has been doing things all along, such as earthquakes. Mother Nature is another evil-doer some are saying. Others say that if we hadn't destroyed the local coast line that Mother Nature created in the first place, the tsunami would have been just a natural event and it wouldn't have hurt so many. So now we're back to people as the ultimate evil-doers.
In sociology, we ask not why things go wrong, but how is it that things go along as smoothly as they do from day to day and year to year. How is it that we can live as peacefully as we do with one another? That's what we need to explain.
