How often do we hear it said "It's only human nature?" And mostly about some gross piece of behaviour as if it couldn't be avoided? Curiously, it is not often said about the best things that people can do. On hearing that someone has risked their life to save another, for some reason we are not inclined to say "Yes, it's human nature." But then, none of these variations of good or bad behaviour are determined by our "nature." We behave differently in different social settings and this is evident from everyday experience. So, in explaining behaviour we must look at the social context in which it happens.
