The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visi… - Carl Sagan

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.

"Essa é uma das razões pelas quais as religiões organizadas não me inspiram confiança. Que líderes dos principais credos reconhecem que suas crenças talvez sejam incompletas ou errôneas, e criam institutos para revelar possíveis deficiências doutrinárias? Além do teste da vida cotidiana, quem verifica sistematicamente as circunstâncias em que os ensinamentos religiosos tradicionais talvez ja não se apliquem? (É concebível que as doutrinas e a ética que podem ter funcionado muito bem nos tempos patriarcais, patrísticos ou medievais sejam totalmente inválidas no mundo bastante diferente que habitamos hoje.) Que sermões examinam imparcialmente a hipótese de Deus? Que prêmios os céticos religiosos ganham das religiões estabelecidas - ou, nesse aspecto, que recompensas os céticos sociais e econômicos recebem da sociedade em que vivem?
A ciência, observa Ann Druyan, está sempre nos sussurrando ao ouvido: "Lembre-se, você é novo nisso. Pode estar equivocado. Já errou antes". Apesar de todo o discurso da humildade, mostrem-me algo comparável na religião. Acredita-se que as Escrituras sejam de inspiração divina - uma expressão com muitos significados.
