“Fireflies out on a warm summer's night, seeing the urgent, flashing, yellow-white phosphorescence below them, go crazy with desire; moths cast to the winds an enchantment potion that draws the opposite sex, wings beating hurriedly, from kilometers away; peacocks display a devastating corona of blue and green and the peahens are all aflutter; competing pollen grains extrude tiny tubes that race each other down the female flower's orifice to the waiting egg below; luminescent squid present rhapsodic light shows, altering the pattern, brightness and color radiated from their heads, tentacles, and eyeballs; a tapeworm diligently lays a hundred thousand fertilized eggs in a single day; a great whale rumbles through the ocean depths uttering plaintive cries that are understood hundreds of thousands of kilometers away, where another lonely behemoth is attentively listening; bacteria sidle up to one another and merge; cicadas chorus in a collective serenade of love; honeybee couples soar on matrimonial flights from which only one partner returns; male fish spray their spunk over a slimy clutch of eggs laid by God-knows-who; dogs, out cruising, sniff each other's nether parts, seeking erotic stimuli; flowers exude sultry perfumes and decorate their petals with garish ultraviolet advertisements for passing insects, birds, and bats; and men and women sing, dance, dress, adorn, paint, posture, self-mutilate, demand, coerce, dissemble, plead, succumb, and risk their lives. To say that love makes the world go around is to go too far. The Earth spins because it did so as it was formed and there has been nothing to stop it since. But the nearly maniacal devotion to sex and love by most of the plants, animals, and microbes with which we are familiar is a pervasive and striking aspect of life on Earth. It cries out for explanation. What is all this in aid of? What is the torrent of passion and obsession about? Why will organisms go without sleep, without food, gladly put themselves in mortal danger for sex? ... For more than half the history of life on Earth organisms seem to have done perfectly well without it. What good is sex?... Through 4 billion years of natural selection, instructions have been honed and fine-tuned...sequences of As, Cs, Gs, and Ts, manuals written out in the alphabet of life in competition with other similar manuals published by other firms. The organisms become the means through which the instructions flow and copy themselves, by which new instructions are tried out, on which selection operates. 'The hen,' said Samuel Butler, 'is the egg's way of making another egg.' It is on this level that we must understand what sex is for. ... The sockeye salmon exhaust themselves swimming up the mighty Columbia River to spawn, heroically hurdling cataracts, in a single-minded effort that works to propagate their DNA sequences into future generation. The moment their work is done, they fall to pieces. Scales flake off, fins drop, and soon--often within hours of spawning--they are dead and becoming distinctly aromatic. They've served their purpose. Nature is unsentimental. Death is built in.”

“A new consciousness is developing which sees the earth as a single organism and recognizes that an organism at war with itself is doomed. We are one planet. One of the great revelations of the age of space exploration is the image of the earth finite and lonely, somehow vulnerable, bearing the entire human species through the oceans of space and time.”

“Long ago, when an early galaxy began to pour light out into the surrounding darkness, no witness could have known that billions of years later some remote clumps of rock and metal, ice and organic molecules would fall together to make place called Earth; or that life would arise and thinking beings evolve who would one day capture a little of that galactic light, and try to puzzle out what had sent it on its way. And after the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being -- and they will know nothing of a place once called Earth.”

“We live in an extraordinary age. These are times of stunning changes in social organization, economic well-being, moral and ethical precepts, philosophical and religious perspectives, and human self-knowledge, as well as in our understanding of that vast universe in which we are imbedded like a grain of sand in a cosmic ocean. As long as there have been human beings, we have posed the deep and fundamental questions, which evoke wonder and stir us into at least a tentative and trembling awareness, questions on the origins of consciousness; life on our planet; the beginnings of the Earth; the formation of the Sun; the possibility of intelligent beings somewhere up there in the depths of the sky; as well as, the grandest inquiry of all - on the advent, nature and ultimate destiny of the universe. For all but the last instant of human history these issues have been the exclusive province of philosophers and poets, shamans and theologians. The diverse and mutually contradictory answers offered demonstrate that few of the proposed solutions have been correct. But today, as a result of knowledge painfully extracted from nature, through generations of careful thinking, observing, and experimenting, we are on the verge of glimpsing at least preliminary answers to many of these questions....If we do not destroy ourselves, most of us will be around for the answers. Had we been born fifty years earlier, we could have wondered, pondered, speculated about these issues, but we could have done nothing about them. Had we been born fifty years later, the answers would, I think, already have been in. Our children will have been taught the answers before most of them will have had the opportunity to even formulate the questions. By far the most exciting, satisfying and exhilarating time to be alive is the time in which we pass from ignorance to knowledge on these fundamental issues; the age where we begin in wonder and end in understanding. In all of the four-billion-year history of the human family, there is only one generation priveleged to live through that unique transitional moment: that generation is ours.”

“You will go through your life thinking there was a day in second grade that you must have missed, when the grown-ups came in and explained, everything important to other kids. they said, 'Look, you're human, you're going to feel isolated and afraid a lot of the time, nad have bad self-esteem, and feel uniquely ruined, but here is the magic phrase that will take this feeling away. It will be like a feather that will lift you out of that fear and self-consciousness every single time, all through your life.' And then they told the cildren who were there that day the magic phrase that everyone else in the world knows about and uses when feeling blue, which only you don't know, because you were home sick the day the grown-ups told the children the way the whole world works. But there was not such a day in school. No one got the instructions. That is the secret of life. Everyone is flailing around, winging it most of the time, trying to find the way out, or through, or up, without a map. This lack of instruction manual is how most people develop compassion, and how they figure out to show up, care, help and serve, as the only way of filling up and being free. Otherwise you gorw up to be someone who needs to dominate and shame others so no one will know that you weren't there the day the instructions were passed out.”

“The Earth is the only world known so far to harbour life. There is nowhere else, at least in the near future, to which our species could migrate. Visit? Yes. Settle? Not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. ... 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.”

“Darwin theorized that mankind (both male and female) evolved alongside each other over millions of years, both reproducing after their own kind before the ability to physically have sex evolved. They did this through “asexuality” (“without sexual desire or activity or lacking any apparent sex or sex organs”). Each of them split in half: “Asexual organisms reproduce by fission (splitting in half).”
