"The myth of our "taker" culture is that the human being is the pinnacle of creation. We are not simply a part of the world; we are its raisons d'etre. We are here to conquer nature, to subdue it, to shape it to meet our own needs. And we have done fairly well at it. The problem is that our successes have not made us happy and they have moved the world into ecological crisis. When one looks at our consumption of medications, our suicide rates, our crime rates, our fear of our neighbors, the deterioration of our environment, it is hard to say that we have created greater happiness or fulfillment than our primitive ancestors knew.
The way our culture explains all the problems is that human beings are flawed. It is our weaknesses that keep us from creating a paradise. We are unworthy. We need supernatural salvation. We are seemingly unable to look at the relationship between our problems and our culture – to realize that the problems are not inherent in human nature, but are the products of the ways in which we have chosen to live. And when we encounter what we call "primitive" peoples who may have more fulfilling lives than we do, we either convert or exterminate them because they could not possibly have anything to teach us, since we have all the answers, and we view them as a threat."
