1. “On ne naît pas femme: on le devient.” - Simone de Beauvoir

2. “Il nous faut partir d'une conception d'ensemble de l'organisme en tant qu'une entité fondamentale de la biologie, puis comprendre comment celui-ci se divise en parties qui respectent son ordre intrinsèque - pour donner un organisme harmonieusement intégré en dépit de sa complexité.” - Brian Goodwin

3. “Oh I believe in loving cats and dogs and children and parents – sometimes – but I don’t believe in romantic love. Of course, there’s the momentary rush of hormones and chemicals that encourages us to mate, but it’s biology – it’s no more inherently mystical than the nicotine in that cigarette you’re smoking” - Amy Jenkins

4. “That enormously complex biological interactions are so flawlessly coordinated as to result in such obvious manifestations as human thought or the electrical activity that dries the heartbeat is as exciting to me -- actually more exciting -- than such phenomena were when I was a small boy and thought them divinely (in the supernatural sense) driven.” - Sherwin B. Nuland

5. “...But I own that I cannot see as plainly as others do, and as I should wish to do, evidence of design and beneficence on all sides of us. There seems to me too much misery in the world. I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidæ with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice... I feel most deeply that the whole subject is too profound for the human intellect. A dog might as well speculate on the mind of Newton. Let each man hope and believe what he can.” - Charles Darwin

6. “Obsolescence is a fate devoutly to be wished, lest science stagnate and die.” - Stephen Jay Gould

7. “We're going to die, and that makes us the lucky ones.” - Richard Dawkins

8. “Dans la nature rien ne se crée, rien ne se perd, tout change.In nature nothing is created, nothing is lost, everything changes.” - Antoine-Laurent de Lavoisier

9. “The ideology and philosophy of neo-Darwinism which is sold by its adepts as a scientific theoretical foundation of biology seriously hampers the development of science and hides from students the field’s real problems.” - Vladimir L. Voeikov

10. “In biology, nothing is clear, everything is too complicated, everything is a mess, and just when you think you understand something, you peel off a layer and find deeper complications beneath. Nature is anything but simple.” - Richard Preston

11. “All disciplines of science are built on the causality of the relationships governing related events. Yet the theory of evolution is built upon the idea of accidental changes that resulted in complex living systems. I was unable to comprehend how the notion that an infinite number of random accidents systematically happened to produce living species, and kept improving these beings, is justified.” - T.H. Janabi

12. “When you look more generally at life on Earth, you find that it is all the same kind of life. There are not many different kinds; there's only one kind. It uses about fifty fundamental biological building blocks, organic molecules.” - Carl Sagan

13. “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

14. “Whenever explaining an event, we must choose from three competing modes of explanation. These are regularity, chance, and design... To attribute an event to design is to say that it cannot reasonably be referred to either regularity or chance.” - William A. Dembski

15. “The fundamental claim of intelligent design is straightforward and easily intelligible: namely, there are natural systems that cannot be adequately explained in terms of undirected natural forces and that exhibit features which in any other circumstance we would attribute to intelligence.” - William A. Dembski

16. “DNA is like a computer program but far, far more advanced than any software ever created.” - Bill Gates

17. “Teaching students the evidence for and against Darwinism is not the same as teaching intelligent design. The U.S. Congress has officially endorsed teaching students 'the full range of scientific views' about Darwinian evolution.” - Jonathan Wells

18. “If Darwinists are opposed to mentioning scientific problems with their view, you would think they would be even more opposed to mentioning intelligent design. Yet Darwinists have been discussing ID in public school science classes for years... Biology textbooks have been mentioning intelligent design since the late 1990s—but only to misrepresent and disparage it.” - Jonathan Wells

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. “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

21. “That natural selection can produce changes within a type is disputed by no one, not even the staunchest creationist. But that it can transform one species into another — that, in fact, has never been observed.” - Robert J. Sawyer

22. “In the abstract, it might be tempting to imagine that irreducible complexity simply requires multiple simultaneous mutations - that evolution might be far chancier than we thought, but still possible. Such an appeal to brute luck can never be refuted... Luck is metaphysical speculation; scientific explanations invoke causes.” - Michael J. Behe

23. “Real arms races are run by highly intelligent, bespectacled engineers in glass offices thoughtfully designing shiny weapons on modern computers. But there's no thinking in the mud and cold of nature's trenches. At best, weapons thrown together amidst the explosions and confusion of smoky battlefields are tiny variations on old ones, held together by chewing gum. If they don't work, then something else is thrown at the enemy, including the kitchen sink - there's nothing "progressive" about that. At its usual worst, trench warfare is fought by attrition. If the enemy can be stopped or slowed by burning your own bridges and bombing your own radio towers and oil refineries, then away they go. Darwinian trench warfare does not lead to progress - it leads back to the Stone Age.” - Michael J. Behe

24. “The most essential prediction of Darwinism is that, given an astronomical number of chances, unintelligent processes can make seemingly-designed systems, ones of the complexity of those found in the cell. ID specifically denies this, predicting that in the absence of intelligent input no such systems would develop. So Darwinism and ID make clear, opposite predictions of what we should find when we examine genetic results from a stupendous number of organisms that are under relentless pressure from natural selection. The recent genetic results are a stringent test. The results: 1) Darwinism’s prediction is falsified; 2) Design’s prediction is confirmed.” - Michael J. Behe

25. “Random mutations much more easily debilitate genes than improve them, and that this is true even of the helpful mutations. Let me emphasize, our experience with malaria’s effects on humans (arguably our most highly studied genetic system) shows that most helpful mutations degrade genes. What’s more, as a group the mutations are incoherent, meaning that they are not adding up to some new system. They are just small changes - mostly degradative - in pre-existing, unrelated genes. The take-home lesson is that this is certainly not the kind of process we would expect to build the astonishingly elegant machinery of the cell. If random mutation plus selective pressure substantially trashes the human genome, why should we think that it would be a constructive force in the long term? There is no reason to think so.” - Michael J. Behe

26. “There were long stretches of DNA in between genes that didn't seem to be doing very much; some even referred to these as "junk DNA," though a certain amount of hubris was required for anyone to call any part of the genome "junk," given our level of ignorance.” - Francis S. Collins

27. “[...] if truth be told, evolution hasn’t yielded many practical or commercial benefits. Yes, bacteria evolve drug resistance, and yes, we must take countermeasures, but beyond that there is not much to say. Evolution cannot help us predict what new vaccines to manufacture because microbes evolve unpredictably. But hasn’t evolution helped guide animal and plant breeding? Not very much. Most improvement in crop plants and animals occurred long before we knew anything about evolution, and came about by people following the genetic principle of ‘like begets like’. Even now, as its practitioners admit, the field of quantitative genetics has been of little value in helping improve varieties. Future advances will almost certainly come from transgenics, which is not based on evolution at all.[review of The Evolving World: Evolution in Everyday Life, Nature 442, 983-984 (31 August 2006)]” - Jerry A. Coyne

28. “Many investigators feel uneasy stating in public that the origin of life is a mystery, even though behind closed doors they admit they are baffled.” - Paul Davies

29. “Even if the intelligent design of some structure has been established, it still is a separate question whether a wise, powerful, and beneficent God ought to have designed a complex, information-rich structure one way or another. For the sake of argument, let's grant that certain designed structures are not simply, as Gould put it, "odd" or "funny," but even cruel. What of it? Philosophical theology has abundant resources for dealing with the problem of evil, maintaining a God who is both omnipotent and benevolent in the face of evil.” - William A. Dembski

30. “The complexity of the simplest known type of cell is so great that it is impossible to accept that such an object could have been thrown together suddenly by some kind of freakish, vastly improbable, event. Such an occurrence would be indistinguishable from a miracle.” - Michael Denton

31. “Perhaps eggs are like neurons, which also are not replenished in adulthood: they know too much. Eggs must plan the party. Sperm need only to show up- wearing top hat and tails, of course. ” - Natalie Angier

32. “Men write more books. Men give more lectures. Men ask more questions after lectures. Men post more e-mail to Internet discussion groups. To say this is due to patriarchy is to beg the question of the behavior's origin. If men control society, why don't they just shut up and enjoy their supposed prerogatives? The answer is obvious when you consider sexual competition: men can't be quiet because that would give other men a chance to show off verbally. Men often bully women into silence, but this is usually to make room for their own verbal display. If men were dominating public language just to maintain patriarchy, that would qualify as a puzzling example of evolutionary altruism—a costly, risky individual act that helps all of one's sexual competitors (other males) as much as oneself. The ocean of male language that confronts modern women in bookstores, television, newspapers, classrooms, parliaments, and businesses does not necessarily come from a male conspiracy to deny women their voice. It may come from an evolutionary history of sexual selection in which the male motivation to talk was vital to their reproduction.” - Geoffrey Miller

33. “But there is nothing in biology yet found that indicates the inevitability of death.” - Richard P. Feynman

34. “The race is now on between the technoscientific and scientific forces that are destroying the living environment and those that can be harnessed to save it. . . . If the race is won, humanity can emerge in far better condition than when it entered, and with most of the diversity of life still intact.” - E.O. Wilson

35. “I thought the fart was a human thing. It's something to do with like, arse cheeks, or whatever.” - Karl Pilkington

36. “Every time you understand something, religion becomes less likely. Only with the discovery of the double helix and the ensuing genetic revolution have we had grounds for thinking that the powers held traditionally to be the exclusive property of the gods might one day be ours. . . .” - James D. Watson

37. “To put it bluntly but fairly, anyone today who doubts that the variety of life on this planet was produced by a process of evolution is simply ignorant—inexcusably ignorant, in a world where three out of four people have learned to read and write.” - Daniel C. Dennett

38. “Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?” - Jacques Monod

39. “Silicon-based life may be impossible for one other reason: silicon bonds readily dissolve in water.” - Steven Johnson

40. “Birth after birth the line unchanging runs,And fathers live transmitted in their sons;Each passing year beholds the unvarying kinds,The same their manners, and the same their minds:Till, as erelong successive buds decay,And insect-shoals successive pass away,Increasing wants the pregnant parent vexWith the fond wish to form a softer sex. ..” - Erasmus Darwin

41. “A grain in the balance will determine which individual shall live and which shall die - which variety or species shall increase in number, and which shall decrease, or finally become extinct.” - Charles Darwin

42. “If we wish to know about a man, we ask 'what is his story--his real, inmost story?'--for each of us is a biography, a story. Each of us is a singular narrative, which is constructed, continually, unconsciously, by, through, and in us--through our perceptions, our feelings, our thoughts, our actions; and, not least, our discourse, our spoken narrations. Biologically, physiologically, we are not so different from each other; historically, as narratives--we are each of us unique.” - Oliver Sacks

43. “Hierarchical organization in biological systems thus is characterized by an exquisite array of delicately and intricately interlocked order, steadily increasing in level and complexity and thereby giving rise neogenetically to emergent properties.” - Clifford Grobstein

44. “Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.” - Edward Osborne Wilson

45. “Individual humans are not super, but the organism of which we are all tiny cellular parts is most certainly that. The life-form that's so big we forget it's there, that turns minerals on its planet into tools to touch the infinite black gap between stars or probe the obliterating pressures at the bottom of the oceans. We are already part of a superbeing, a monster, a god, a living process that is so all encompassing that it is to an individual life what water is to a fish. We are cells in the body of a three-billion-year-old life-form whose roots are in the Precambrian oceans and whose genetic wiring extends through the living structures of everything on the planet, connecting everything that has ever lived in one immense nervous system.” - Grant Morrison

46. “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

47. “Some believe what separates men from animals is our ability to reason. Others say it’s language or romantic love, or opposable thumbs. Living here in this lost world, I’ve come to believe it is more than our biology. What truly makes us human is our unending search, our abiding desire for immortality.” - Arthur Conan Doyle

48. “The male frog, in mating season," said Crake, "makes as much noise as it can. The females are attracted to the male frog with the biggest, deepest voice because it suggests a more powerful frog, one with superior genes. Small male frogs - it's been documented - discover that if they position themselves in empty drainpipes, the pipe acts as a voice amplifier, and the small frog appears much larger than it really is.""So?""So that's what art is, for the artist," said Crake. "An empty drainpipe. An amplifier. A stab at getting laid.""Your analogy falls down when it comes to female artists," said Jimmy. "They're not in it to get laid. They'd gain no biological advantage from amplifying themselves, since potential mates would be deterred rather than attracted by this sort of amplification. Men aren't frogs, they don't want women who are ten times bigger than them.""Female artists are biologically confused," said Crake.” - Margaret Atwood

49. “The offspring cannot rely on its parents for disinterested guidance. One expects the offspring to be preprogrammed to resist some parental manipulation while being open to other forms. When the parent imposes an arbitrary system of reinforcement (punishment and reward) in order to manipulate the offspring to act against its own best interests, selection will favor offspring that resist such schedules of reinforcement.” - Robert Trivers

50. “Our brains contain one hundred billion nerve cells (neurons). Each neuron makes links with ten thousand other neurons to form an incredible three dimensional grid. This grid therefore contains a thousand trillion connections - that's 1,000,000,000,000,000 (a quadrillion). It's hard to imagine this, so let's visualise each connection as a disc that's 1mm thick. Stack up the quadrillion discs on top of each other and they will reach the sun (which is ninety-three million miles from the earth) and back, three times over.” - Nessa Carey

51. “Thus, by science I mean, first of all, a worldview giving primacy to reason and observation and a methodology aimed at acquiring accurate knowledge of the natural and social world. This methodology is characterized, above all else, by the critical spirit: namely, the commitment to the incessant testing of assertions through observations and/or experiments — the more stringent the tests, the better — and to revising or discarding those theories that fail the test. One corollary of the critical spirit is fallibilism: namely, the understanding that all our empirical knowledge is tentative, incomplete and open to revision in the light of new evidence or cogent new arguments (though, of course, the most well-established aspects of scientific knowledge are unlikely to be discarded entirely).. . . I stress that my use of the term 'science' is not limited to the natural sciences, but includes investigations aimed at acquiring accurate knowledge of factual matters relating to any aspect of the world by using rational empirical methods analogous to those employed in the natural sciences. (Please note the limitation to questions of fact. I intentionally exclude from my purview questions of ethics, aesthetics, ultimate purpose, and so forth.) Thus, 'science' (as I use the term) is routinely practiced not only by physicists, chemists and biologists, but also by historians, detectives, plumbers and indeed all human beings in (some aspects of) our daily lives. (Of course, the fact that we all practice science from time to time does not mean that we all practice it equally well, or that we practice it equally well in all areas of our lives.)” - Alan Sokal

52. “Mais de toute façon, engendrer, allaiter ne sont pas des activités, ce sont des fonctions naturelles; aucun projet n'y est engagé; c'est pourquoi la femme n'y trouve pas le motif d'une affirmation hautaine de son existence; elle subit passivement son destin biologique.” - Simone de Beauvoir

53. “A grand and almost untrodden field of inquiry will be opened, on the causes and laws of variation, on correlation of growth, on the effects of use and disuse, on the direct actions of external conditions, and so forth.” - Charles Darwin

54. “Averages might mean something to bureaucrats and engineers, but the sea had no struck with statistics: it was a succession of unpredictable circumstances and extremes.” - Frank Schatzing

55. “Were it not for the melanin in our skin, myoglobin in our muscles and haemoglobin in our blood, we would be the colour of mitochondria. And, if this were so, we would change colour when we exercised or ran out of breath, so that you could tell how energized someone was from his or her colour.” - Guy Brown

56. “In Galapagos, as elsewhere, things of the mind, including intellectual ramifications from evolutionary theory, and things of the spirit, like the feeling one gets from a Queen Anne’s lace of stars in the moonless Galapagean sky, struggle toward accommodation with an elementary desire for material comfort…because so many regard this archipelago as preeminently a terrain of the mind and spirit, a locus of biological thought and psychological rejuvenation. The sheer strength of Darwin’s insight into the development of biological life gently urges a visitor to be more than usually observant here- to notice, say, that while the thirteen Galapagean finches are all roughly the same hue, it is possible to separate them according to marked differences in the shapes of their bills and feeding habits.” - Barry Lopez

57. “It was badly received by the generation to which it was first addressed, and the outpouring of angry nonsense to which it gave rise is sad to think upon. But the present generation will probably behave just as badly if another Darwin should arise, and inflict upon them that which the generality of mankind most hate—the necessity of revising their convictions. Let them, then, be charitable to us ancients; and if they behave no better than the men of my day to some new benefactor, let them recollect that, after all, our wrath did not come to much, and vented itself chiefly in the bad language of sanctimonious scolds. Let them as speedily perform a strategic right-about-face, and follow the truth wherever it leads.” - Thomas Henry Huxley

58. “Threats to our standing in the eyes of others are remarkably potent biologically, almost as powerful as those to our very survival.” - Daniel Goleman

59. “[...] we have in our treatise a series of fifty-seven examinations, almost exclusively of injuries of the human body forming a group of observations furnishing us with the earliest known nucleus of fact regarding the anatomy, physiology and pathology of the human body. Crude and elementary as they are, the method by which they were collected was scientific, and these observations, together with the diagnoses and the explanatory commentary in the ancient glosses, form the oldest body of science now extant.” - James Henry Breasted
