Civilisation is not innate but has to be learned by each generation, and it's evolution may be different for each succeeding generation. And having written that I am wondering what civilisation is! Perhaps it is a veneer, or a barrier between our needs and our wants. If that is so then we can be a noble or a savage and it has little to do with our level of 'civilisation' and more to do with our perception of self, community and the realisation, that as terry said, we are all part of nature. One natural disaster and we could be living in savage uncivilised conditions in New Orleans. How we behave then then is a choice we have to make ourselves, as many of our ancestors have before us.
