"In our tenure on this planet we have accumulated dangerous evolutionary baggage, hereditary propensities for aggression and ritual, submission to leaders and hostility to outsiders, which place our survival in some question. But we have also acquired compassion for others, love for our children and our children's children, a desire to learn from history, and a great soaring passionate intelligence--the clear tools for our continued survival and prosperity. Which aspects of our nature will prevail is uncertain, particularly when our vision and understanding and prospects are bound exclusively to the Earth--or, worse, to one small part of it. But up there in the immensity of the Cosmos, an inescapable perspective awaits us." - Carl Sagan
