Earth Quotes

“Every living thing is, from the cosmic perspective, incredibly lucky simply to be alive. Most, 90 percent and more, of all the organisms that have ever lived have died without viable offspring, but not a single one of your ancestors, going back to the dawn of life on Earth, suffered that normal misfortune. You spring from an unbroken line of winners.”

“I have already indicated to you the meaning of the word religion, as applied to Islam. The truth is that Islam is not a Church. It is a State conceived as a contractual organism long before Rousseau ever thought of such a thing, and animated by an ethical ideal which regards man not as an earth-rooted creature, defined by this or that portion of the earth, but as a spiritual being understood in terms of a social mechanism, and possessing rights and duties as a living factor in that mechanism.”

“The earth is not a mechanism but an organism, a being with its own life and its own reasons, where the support and sustenance of the human animal is incidental. If man in his newfound power and vanity persists in the attempt to remake the planet in his own image, he will succeed only in destroying himself - not the planet. The earth will survive our most ingenious folly.”

It is conceivable, of course, that life originated more than once on the early earth but that all except one life form died out early, leaving a single lineage as the ancestor of life as we know it. If this did happen, it was the first important species extinction.”

“The issue, as correctly emphasized by Carl Sagan, is the probability of the evolution of high intelligence and an electronic civilization on an inhabited world. Once we have life (and almost surely it will be very different from life on Earth), what is the probability of its developing a lineage with high intelligence? On Earth, among millions of lineages of organisms and perhaps 50 billion speciation events, only one led to high intelligence; this makes me believe in its utter improbability.”

“I have been trying to think of the earth as a kind of organism, but it is no go. I cannot think of it this way. It is too big, too complex, with too many working parts lacking visible connections. The other night, driving through a hilly, wooded part of southern New England, I wondered about this. If not like an organism, what is it like, what is it most like? Then, satisfactorily for that moment, it came to me: it is most like a single cell”
