1. “Humans have evolved to their relatively high state by retaining the immature characteristics of their ancestors. Humans are the most advanced of mammals – although a case could be made for the dolphins – because they seldom grow up. Behavioral traits such as curiosity about the world, flexibility of response, and playfulness are common to practically all young mammals but are usually rapidly lost with the onset of maturity in all but humans. Humanity has advanced, when it has advanced, not because it has been sober, responsible and cautious, but because it has been playful, rebellious, and immature.” - Tom Robbins

2. “Nevertheless, it is even harder for the average ape to believe that he has descended from man.” - H.L. Mencken

3. “And people who believe in God think God has put human beings on earth because they think human beings are the best animal, but human beings are just an animal and they will evolve into another animal, and that animal will be cleverer and it will put human beings into a zoo, like we put chimpanzees and gorillas into a zoo. Or human beings will all catch a disease and die out or they will make too much pollution and kill themselves, and then there will only be insects in the world and they will be the best animal.” - Mark Haddon

4. “The geologic cycle is a bunch of balarky.” - Howard Pyle

5. “...the student of prehistoric man...cannot reject [the Castenedolo skull] as false without doing injury to his sense of truth, and he cannot accept it as fact without shattering his accepted beliefs.” - Arthur Keith

6. “I mean to say, I know perfectly well that I've got, roughly speaking, half the amount of brain a normal bloke ought to possess. And when a girl comes along who has about twice the regular allowance, she too often makes a bee line for me with the love light in her eyes. I don't know how to account for it, but it is so.""It may be Nature's provision for maintaining the balance of the species, sir.” - Wodehouse

7. “The playwright Edward Albee has characterized [the suddenness of the appearance of fruits and flowers in evolutionary history] as 'that heartbreaking second when it all got together: the sugars and the acids and the ultraviolets, and the next thing you knew there were tangerines and string quartets.” - Adam Leith Gollner

8. “As his body became more and more defenseless, so his means of offense became steadily more frightful.” - Arthur C. Clarke

9. “Innovation is an evolutionary process, so it's not necessary to be radical all the time.” - Marc Jacobs

10. “What's the matter? What's the antimatter? Does it antimatter?” - Wes Nisker

11. “Perhaps he knew, there in the grass by the waters, that he had before him an immense journey.” - Loren Eiseley

12. “Even if it were true that evolution, or the teaching of evolution, encouraged immorality that would not imply that the theory of evolution was false.” - Richard Dawkins

13. “Scientific theories never dictate human values, but they can often cast new light on ethical issues. From a sexual selection viewpoint, moral philosophy and political theory have mostly been attempts to shift male human sexual competitiveness from physical violence to the peaceful accumulation of wealth and status. The rights to life, liberty, and property are cultural inventions that function, in part, to keep males from killing and stealing from one another while they compete to attract sexual partners.” - Geoffrey Miller

14. “Every time we exterminate a predator, we are in a sense creating a new predator.” - David Rains Wallace

15. “Nature is a hanging judge," goes an old saying. Many tragedies come from our physical and cognitive makeup. Our bodies are extraordinarily improbable arrangements of matter, with many ways for things to go wrong and only a few ways for things to go right. We are certain to die, and smart enough to know it. Our minds are adapted to a world that no longer exists, prone to misunderstandings correctable only by arduous education, and condemned to perplexity about the deepest questions we can ascertain.” - Steven Pinker

16. “All we know of the Missing Link is that he is missing - and he won't be missed either.” - G.K. Chesterton

17. “Life is unlikely to end with humans, even if we burn in a nuclear holocaust. The relentless wheel of evolution will pick up from where we leave off and roll to it's predestined goal. If the human mind continues to evolve, enlarge, and expand, so that we are able to recognize our kinship with the creations around us, so that we are able to grasp our oneness with the cosmos, and so that we merge in yoga with the Divine, the long cosmic cycle will disclose its cryptic secret, and the long saga of billions of years of evolution will display its profound significance.” - Roy J. Mathew

18. “I recently asked more than seventy eminent researchers if they would have done I their work differently if they had thought Darwin's theory was wrong. The responses were all the same: no. I also examined the outstanding biodiscoveries of the past century: the discovery of the double helix; the characterization of the ribosome: the mapping of genomes; research on medications and drug reactions: improvements in food production and sanitation; the development of new surgeries; and others. I even queried biologists working in areas where one would expect the Darwinian paradigm to have most benefited research, such as the emergence of resistance to antibiotics and pesticides. Here, as elsewhere, I found that Darwin's theory had provided no discernible guidance, but was brought in, after the breakthroughs, as an interesting narrative gloss.” - Philip S. Skell

19. “Teachers seeking to 'teach the controversy' over Darwinian evolution in today's climate will likely be met with false warnings that it is unconstitutional to say anything negative about Darwinian evolution. Students who attempt to raise questions about Darwinism, or who try to elicit from the teacher an honest answer about the status of intelligent design theory will trigger administrators' concerns about whether they stand in Constitutional jeopardy. A chilling effect on open inquiry is being felt in several states already, including Ohio. South Carolina, and Pennsylvania. [District Court] Judge Jones's message is clear: give Darwin only praise, or else face the wrath of the judiciary.” - David K. DeWolf

20. “Darwinism by itself did not produce the Holocaust, but without Darwinism... neither Hitler nor his Nazi followers would have had the necessary scientific underpinnings to convince themselves and their collaborators that one of the worlds greatest atrocities was really morally praiseworthy.” - Richard Weikart

21. “The controversy between Darwinism and intelligent design has the characteristics of major scientific revolutions in the past. Darwinists are losing power because they treat with contempt the very people on whom they depend the most: American taxpayers. The outcome of this scientific revolution will be decided by young people who have the courage to question dogmatism and follow the evidence wherever it leads.” - Jonathan Wells

22. “Let us accept the possibility that there is, at death, not an abrupt cessation of energy, rather a dispersal. This seems more than reasonable to me. Mind you, I've owned a series of old cars, and I"m used to turning off the motor only to experience a series of rumblings and explosions that would shame many a volcano. This is the sort of thing I'm conceptualizing, a kind of clunky running-on. And just as some cars are more susceptible to this behavior, so people vary in the length of time, and the force with which, their energy sputters and gasps. . . My example is overly dramatic, but it is not wholly unreasonable, and it serves to make this genetic mutation a player at the evolutionary table. You see what I'm getting at: a biologically and evolutionally sound model for the soul. (I didn't say I'd achieved it.) Let's conceive of the soul as an aura that human beings wear on their backs, cumberson as a tortoise's carapace. Some are larger than others.” - Paul Quarrington

23. “Before you can ask 'Is Darwinian theory correct or not?', You have to ask the preliminary question 'Is it clear enough so that it could be correct?'. That's a very different question. One of my prevailing doctrines about Darwinian theory is 'Man, that thing is just a mess. It's like looking into a room full of smoke.' Nothing in the theory is precisely, clearly, carefully defined or delineated. It lacks all of the rigor one expects from mathematical physics, and mathematical physics lacks all the rigor one expects from mathematics. So we're talking about a gradual descent down the level of intelligibility until we reach evolutionary biology.” - David Berlinski

24. “These mysteries about how we evolved should not distract us from the indisputable fact that we did evolve.” - Jerry A. Coyne

25. “A wonderful area for speculative academic work is the unknowable. These days religious subjects are in disfavor, but there are still plenty of good topics. The nature of consciousness, the workings of the brain, the origin of aggression, the origin of language, the origin of life on earth, SETI and life on other worlds...this is all great stuff. Wonderful stuff. You can argue it interminably. But it can't be contradicted, because nobody knows the answer to any of these topics.” - Michael Crichton

26. “But then arises the doubt, can the mind of man, which has, as I fully believe been developed from a mind as low as that possessed by the lowest animal, be trusted when it draws such grand conclusions?” - Charles Darwin

27. “Dedicated to the memory of MY FATHER. For if I had not believed that he would have wished me to give such help as I could toward making his life's work of service to mankind, I should never have been led to write this book.” - Leonard Darwin

28. “Of all the problems which will have to be faced in the future, in my opinion, the most difficult will be those concerning the treatment of the inferior races of mankind.” - Leonard Darwin

29. “In the past the man has been first; in the future the system must be first.” - Frederick Winslow Taylor

30. “The chicken is only an egg’s way for making another egg.” - Richard Dawkins

31. “The following proposition seems to me in a high degree probable—namely, that any animal whatever, endowed with well-marked social instincts, the parental and filial affections being here included, would inevitably acquire a moral sense or conscience, as soon as its intellectual powers had become as well, or nearly as well developed, as in man. For, firstly, the social instincts lead an animal to take pleasure in the society of its fellows, to feel a certain amount of sympathy with them, and to perform various services for them.” - Charles Darwin

32. “If you ever start taking things too seriously, just remember that we are talking monkeys on an organic spaceship flying through the universe.” - Joe Rogan

33. “I think the discomfort that some people feel in going to the monkey cages at the zoo is a warning sign.” - Carl Sagan

34. “The Universe was a damned silly place at best . . . but the least likely explanation for its existence was the no-explanation of random chance, the conceit that some abstract somethings "just happened" to be some atoms that "just happened" to get together in configurations which "just happened" to look like consistent laws and then some of these configurations "just happened" to possess self-awareness and that two such "just happened" to be the Man from Mars and the other a bald-headed old coot with Jubal himself inside. No, Jubal would not buy the "just happened" theory, popular as it was with men who called themselves scientists. Random chance was not a sufficient explanation of the Universe--in fact, random chance was not sufficient to explain random chance; the pot could not hold itself.” - Robert A. Heinlein

35. “When faced with a radical crisis, when the old way of being in the world, of interacting with each other and with the realm of nature doesn't work anymore, when survival is threatened by seemingly insurmountable problems, an individual life-form -- or a species -- will either die or become extinct or rise above the limitations of its condition through an evolutionary leap.” - Eckhart Tolle

36. “It is failure that guides evolution; perfection provides no incentive for improvement, and nothing is perfect.” - COLSON WHITEHEAD

37. “Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.” - Richard Dawkins

38. “People cited violation of the First Amendment when a New Jersey schoolteacher asserted that evolution and the Big Bang are not scientific and that Noah's ark carried dinosaurs. This case is not about the need to separate church and state; it's about the need to separate ignorant, scientifically illiterate people from the ranks of teachers.” - Neil deGrasse Tyson

39. “Not that chance dominated events in the early Solar System, for scientific determinism was also functioning. But chance is an essential factor in all evolutionary events, and the birth and development of our planetary system were not exceptions.” - Eric Chaisson

40. “New Rule: Stop asking Miss USA contestants if they believe in evolution. It’s not their field. It’s like asking Stephen Hawking if he believes in hair scrunchies. Here’s what they know about: spray tans, fake boobs and baton twirling. Here’s what they don’t know about: everything else. If I cared about the uninformed opinions of some ditsy beauty queen, I’d join the Tea Party.” - Bill Maher

41. “An event is not any more intrinsically intelligible or unintelligible because of the pace at which it moves. For a man who does not believe in a miracle, a slow miracle would be just as incredible as a swift one. The Greek witch may have turned sailors to swine with a stroke of the wand. But to see a naval gentleman of our acquaintance looking a little more like a pig every day, till he ended with four trotters and a curly tail, would not be any more soothing. It might be rather more creepy and uncanny.” - G.K. Chesterton

42. “While most science moves in a sort of curve, being constantly corrected by new evidence, this science flies off into space in a straight line uncorrected by anything. But the habit of forming conclusions, as they can really be formed in more fruitful fields, is so fixed in the scientific mind that it cannot resist talking like this. It talks about the idea suggested by one scrap of bone as if it were something like the aeroplane which is constructed at last out of whole scrapheaps of scraps of metal. The trouble with the professor of the prehistoric is that he cannot scrap his scrap. The marvellous and triumphant aeroplane is made out of a hundred mistakes. The student of origins can only make one mistake and stick to it.” - G.K. Chesterton

43. “Does not… the ear of Handel predict the witchcraft of harmonic sound?” - Ralph Waldo Emerson

44. “We live in the Age of the Higher Brain, the cerebral cortex that has grown enormously over the last few millennia, overshadowing the ancient, instinctive lower brain. The cortex is often called the new brain, yet the old brain held sway in humans for millions of years, as it does today in most living things. The old brain can’t conjure up ideas or read. But it does possess the power to feel and, above all, to be. It was the old brain that caused our forebears to sense the closeness of a mysterious presence everywhere in Nature.” - Deepak Chopra

45. “Don't creationists ever wonder about the fact that the paleontologists found ape-like skulls with the 'human leg and foot bones,' rather than the other way around, i.e., human skulls with 'ape leg and foot bones?' . . . Come on, creationists, think about it! Did God hide the human skulls, only leaving behind leg and foot bones belonging to human midgets with misshapen feet, and mix such bones only with the skulls of ape-like creatures with larger cranial capacities than living apes? What a 'kidder' the creationists' God must be.” - Edward Babinski

46. “Whereas modern cynicism brought despair about the ability of the human species to realize laudable ideals, postmodern cynicism doesn't — not because it's optimistic, but because it can't take ideals seriously in the first place. The prevailing attitude is Absurdism. A postmodern magazine may be irreverent, but not bitterly irreverent, for it's not purposefully irreverent; its aim is indiscriminate, because everyone is equally ridiculous. And anyway, there's no moral basis for passing judgment. Just sit back and enjoy the show.” - Robert Wright

47. “Today, and let us celebrate this fact, We can eat the light of our beloved, warmed by compassion or cooled by intellectual feeling. And if we are surprised, and some of us disappointed, that the light is now only green - well, such was the vital probability awaiting us. We have, after all, an increase in the energy available for further evolution; we can use the energy of our position relative to the probabilities in the future to reach the future we desire. The full use of this energy is just beginning to be explored, and we have the opportunity open to few generations to create our best opportunities. We must not slacken in our desire now if we desire a future. The pressure of probabilities on the present increases the momentum of evolution, and as the voluble helix turns, and turns us away from our improbable satiation, we can see that the shadow cast on the present from the future is not black but rainbowed, brilliant with lemon yellow, plum-purple, and cherry-red. I have no patience with those who say that their desire for light is satisfied. Or that they are bored. I have myself a still unsatisfied appetite for green: eucalyptus, celadon, tourmaline, and apple. ("Desire")” - William S. Wilson

48. “A biochemist colleague has kindly provided me with a bottle of hydrogen peroxide, and enough hydroquinone for 50 bombardier beetles, I am now about to mix the two together. According to the above, they will explode in my face. Here goes...Well... I'm still here! I poured the hydrogen peroxide into the hydroquinone, and absolutely nothing happened. It didn't event get warm!” - Richard Dawkins

49. “Pain and darkness have been our lot since the Fall of Man. But there must be some hope that we can rise to a higher level ... that consciousness can evolve to a plane more benevolent than its counterpoint of a universe hardwired to indifference.” - Dan Simmons

50. “In a perfectly designed world —one with no history— we would not have to suffer everything from hemorrhoids to cancer.” - Neil Shubin

51. “Don't blame me. That's evolution. Evolution's always hard. Hard and bleak. No such thing as happy evolution.” - Haruki Murakami

52. “As an anonymous wit is supposed to have put it: "Hydrogen is a light, odorless gas which, given enough time, changes into people.” - David Christian

53. “Deep in the sea are riches beyond compare. But if you seek safety, it is on the shore.” - Idries Shah

54. “We are here because over billions of years, countless variables fell into place, any of which could have taken another path. We are essentially a beautiful fluke, as are the millions of other species with which we share this planet. Our cells are composed of atoms and dust particles from distant galaxies, and from the billions of living organisms that inhabited this planet before us.” - Wendy Mass

55. “I’ll give you a theory: Man’s closest relative is not the chimpanzee, as the TV people believe, but is, in fact, the dog.” - Garth Stein

56. “The affinities of all the beings of the same class have sometimes been represented by a great tree.I believe this simile largely speaks the truth. The green and budding twigs may represent existing species; and those produced during former years may represent the long succession of extinct species. At each period of growth all the growing twigs have tried to branch out on all sides, and to overtop and kill the surrounding twigs and branches, in the same manner as species and groups of species have at all times overmastered other species in the great battle for life. The limbs divided into great branches, and these into lesser and lesser branches, were themselves once, when the tree was young, budding twigs; and this connection of the former and present buds by ramifying branches may well represent the classification of all extinct and living species in groups subordinate to groups. Of the many twigs which flourished when the tree was a mere bush, only two or three, now grown into great branches, yet survive and bear the other branches; so with the species which lived during long-past geological periods, very few have left living and modified descendants. From the first growth of the tree, many a limb and branch has decayed and dropped off; and these fallen branches of various sizes may represent those whole orders, families, and genera which have now no living representatives, and which are known to us only in a fossil state. As we here and there see a thin straggling branch springing from a fork low down in a tree, and which by some chance has been favoured and is still alive on its summit, so we occasionally see an animal like the Ornithorhynchus or Lepidosiren, which in some small degree connects by its affinities two large branches of life, and which has apparently been saved from fatal competition by having inhabited a protected station. As buds give rise by growth to fresh buds, and these, if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever-branching and beautiful ramifications.” - Charles Darwin

57. “As many critics of religion have pointed out, the notion of a creator poses an immediate problem of an infinite regress. If God created the universe, what created God? To say that God, by definition, is uncreated simply begs the question. Any being capable of creating a complex world promises to be very complex himself. As the biologist Richard Dawkins has observed repeatedly, the only natural process we know of that could produce a being capable of designing things is evolution.” - Sam Harris

58. “It seems to me that the Russian prestige is declining and that America holds in its hands the immediate future of the world: as long as America knows how to develop the sense of the earth at the same time as her sense of liberty." [Written from Peking, October 1945, on the eve of departure, after having been stuck there since the war began.]” - Pierre Teilhard De Chardin

59. “So long as we are driven by the need to make up for our needs; by the restless sense that we are not yet fully assured of our place in the world and our hold on its swarming phenomena; so long as there is more to be discovered and made, more to grasp for and make real, we must go on inventing ourselves.” - David Malouf

60. “In evolutionary terms, that means we asked for it.” - Sharon Moalem
