Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light....Like it or not, for the moment the Earth is where we make our stand....There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known. - Carl Sagan
