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.

There is only one home to the life of a river-mussel; there is only one home to the life of a tortoise; there is only one shell to the soul of man: there is only one world to the spirit of our race. If that world leaves its course and smashes on boulders of the great void, whose world will give us shelter?
Wole Soyinka
Theory should be ever more demanding of our empirical resources. Simultaneously, data should be ever more demanding of the empirical relevance of theory and of the theorist's expertise in working imaginatively on problems of the world, rather than on stylized problems of the imagination.
Vernon L. Smith
