To have a firm persuasion in our work -- to feel that what we do is right for ourselves and good for the world at exactly the same time — is one of the great triumphs of human existence... To have a firm persuasion, to set out boldly in our work, is to make a pilgrimage of our labors, to understand that the consummation of work lies not only in what we have done, but who we have become while accomplishing the task... Work, at its best, is one of the great human gateways to the eternal and the timeless.
We succeeded in taking that picture [from deep space], and, if you look at it, you see a dot. That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there on a mote of dust, suspended in a sunbeam. The earth is a very small stage in a vast cosmic arena ... It's been said that astronomy is a humbling, and I might add, a character building experience. To my mind, 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 and compassionately with one another and to preserve and cherish that pale blue dot, the only home we've ever known.
