"If your pet is dying in pain, you will be condemned for cruelty if you do not summon the vet to give him a general anaesthetic from which he will not come round. But if your doctor performs exactly the same merciful service for you when you are dying in pain, he runs the risk of being prosecuted for murder. When I am dying, I should like my life to be taken out under a general anaesthetic, exactly as if it were a diseased appendix. But I shall not be allowed that privilege, because I have the ill-luck to be born a member of Homo sapiens rather than, for example, Canis familiaris or Felis catus. At least, that will be the case unless I move to a more enlightened place like Switzerland, the Netherlands or Oregon. Why are such enlightened places so rare? Mostly because of the influence of religion."

"The feeling that members of one's own species deserve special moral consideration as compared with members of other species is old and deep. Killing people outside war is the most seriously-regarded crime ordinarily committed. The only thing more strongly forbidden by our culture is eating people (even if they are already dead). We enjoy eating members of other species, however. Many of us shrink from judicial execution of even the most horrible human criminals, while we cheerfully countenance the shooting without trial of fairly mild animal pests. Indeed we kill members of other harmless species as a means of recreation and amusement. A human foetus, with no more human feeling than an amoeba, enjoys a reverence and legal protection far in excess of those granted to an adult chimpanzee. Yet the chimp feels and thinks and—according to recent experimental evidence—may even be capable of learning a form of human language. The foetus belongs to our own species, and is instantly accorded special privileges and rights because of it. Whether the ethic of 'speciesism', to use Richard Ryder's term, can be put on a logical footing any more sound than that of 'racism', I do not know. What I do know is that it has no proper basis in evolutionary biology."

"The director of a zoo is entitled to "put down" a chimpanzee that is surplus to requirements, while any suggestion that he might "put down" a redundant keeper or ticket-seller would be greeted with howls of incredulous outrage. The chimpanzee is the property of the zoo. Humans are nowadays not supposed to be anybody's property, yet the rationale for discriminating against chimpanzees is seldom spelled out, and I doubt if there is a defensible rationale at all. Such is the breathtaking speciesism of our Christian-inspired attitudes, the abortion of a single human zygote (most of them are destined to be spontaneously aborted anyway) can arouse more moral solicitude and righteous indignation than the vivisection of any number of intelligent adult chimpanzees! [...] The only reason we can be comfortable with such a double standard is that the intermediates between humans and chimps are all dead."

"Evolution too, like embryonic development, is gradual. Every one of our ancestors, back to the common root we share with chimpanzees and beyond, belonged to the same species as its own parents and its own children. And likewise for the ancestors of a chimpanzee, back to the same shared progenitor. We are linked to modern chimpanzees by a V-shaped chain of individuals who once lived and breathed and reproduced, each link in the chain being a member of the same species as its neighbours in the chain, no matter that taxonomists insist on dividing them at convenient points and thrusting discontinuous labels upon them. If all the intermediates, down both forks of the V from the shared ancestor, had happened to survive, moralists would have to abandon their essentialist, "speciesist" habit of placing Homo sapiens on a sacred plinth, infinitely separate from all other species. Abortion would no more be "murder" than killing a chimpanzee—or, by extension, any animal. Indeed an early-stage human embryo, with no nervous system and presumably lacking pain and fear, might defensibly be afforded less moral protection than an adult pig, which is clearly well equipped to suffer. Our essentialist urge toward rigid definitions of "human" (in debates over abortion and animal rights) and "alive" (in debates over euthanasia and end-of-life decisions) makes no sense in the light of evolution and other gradualistic phenomena."

"It is better for the genes of Darwin's wasp that the caterpillar should be alive, and therefore fresh, when it is eaten, no matter what the cost in suffering. If Nature were kind, She would at least make the minor concession of anesthetizing caterpillars before they were eaten alive from within. But Nature is neither kind nor unkind. She is neither against suffering nor for it. Nature is not interested in suffering one way or the other unless it affects the survival of DNA. It is easy to imagine a gene that, say, tranquilizes gazelles when they are about to suffer a killing bite. Would such a gene be favored by natural selection? Not unless the act of tranquilizing a gazelle improved that gene's chances of being propagated into future generations. It is hard to see why this should be so, and we may therefore guess that gazelles suffer horrible pain and fear when they are pursued to the death– as many of them eventually are."

"Wild animals almost never die of old age: starvation, disease, or predators catch up with them long before they become really senile. Until recently this was true of man too. Most animals die in childhood, many never get beyond the egg stage. Starvation and other causes of death are the ultimate reason why populations cannot increase indefinitely. But as we have seen for our own species, there is no necessary reason why it ever has to come to that. If only animals would control their birth rates, starvation need never happen."

"The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so. If there ever is a time of plenty, this very fact will automatically lead to an increase in the population until the natural state of starvation and misery is restored."

"If you're seen to criticise Islam you are often accused of racism, which is absurd."

"A body is a patchwork of compromises."

"I'm all for offending people's religion. I think it should be offended at every opportunity"

"If any remedy is tested under controlled scientific conditions and proved to be effective, it will cease to be alternative and will simply become medicine. So-called alternative medicine either hasn't been tested or it has failed its tests."

"Evolution is a fact. Beyond reasonable doubt, beyond serious doubt, beyond sane, informed, intelligent doubt, beyond doubt evolution is a fact. The evidence for evolution is at least as strong as the evidence for the Holocaust, even allowing for eye witnesses to the Holocaust. It is the plain truth that we are cousins of chimpanzees, somewhat more distant cousins of monkeys, more distant cousins still of aardvarks and manatees, yet more distant cousins of bananas and turnips... continue the list as long as desired."

"[...] my interest in biology has been largely driven by questions about origins and the nature of life, rather than – as is the case for most young biologists I have taught – by a love of natural history."

"People are terrified of being thought racist, there's an awful confusion in many people's minds. They think Islam is a race, which of course it isn't"

"If the alternative that's being offered to what physicists now talk about - a big bang, a spontaneous singularity which gave rise to the origin of the universe - if the alternative to that is a divine intelligence, a creator, which would have to have been complicated, statistically improbable, the very kind of thing which scientific theories such as Darwin's exists to explain, then immediately we see that however difficult and apparently inadequate the theory of the physicists is, the theory of the theologians - that the first course was a complicated intelligence - is even more difficult to accept. They're both difficult but the theory of the cosmic intelligence is even worse. What Darwinism does is to raise our consciousness to the power of science to explain the existence of complex things and intelligences, and creative intelligences are above all complex things, they're statistically improbable. Darwinism raises our consciousness to the power of science to explain how such entities - and the human brain is one - can come into existence from simple beginnings. However difficult those simple beginnings may be to accept, they are a whole lot easier to accept than complicated beginnings. Complicated things come into the universe late, as a consequence of slow, gradual, incremental steps. God, if he exists, would have to be a very, very, very complicated thing indeed. So to postulate a God as the beginning of the universe, as the answer to the riddle of the first cause, is to shoot yourself in the conceptual foot because you are immediately postulating something far far more complicated than that which you are trying to explain. Now, physicists cope with this problem in various ways, which may seem somewhat unconvincing. For example, they suggest that our universe is but one bubble in foam of universes, the multiverse, and each bubble in the foam has a different set of laws and constants. And by the anthropic principle we have to be - since we're here talking about it - in the kind of bubble, with the kind of laws and constants, which are capable of giving rise to the evolutionary process and therefore to creatures like us. That is one current physicists' explanation for how we exist in the kind of universe that we do. It doesn't sound so shatteringly convincing as say Darwin's own theory, which is self-evidently very convincing. Nevertheless, however unconvincing that may sound, it is many, many, many orders of magnitude more convincing than any theory that says complex intelligence was there right from the outset. If you have problems seeing how matter could just come into existence - try thinking about how complex intelligent matter, or complex intelligent entities of any kind, could suddenly spring into existence, it's many many orders of magnitude harder to understand."

""What is it that makes natural selection succeed as a solution to the problem of improbability, whereas chance and design both fail at the starting gate? The answer is that natural selection is a cumulative process, which breaks the problem of improbability up into small pieces. Each of the small pieces is slightly improbable, but not prohibitively so. (p. 153)"

"Amusingly, it [astrology] falls foul of our modern taboo against lazy stereotyping. How would we react if a newspaper published a daily column that read something like this: "Germans: It is in your nature to be hard-working and methodical, which should serve you well at work today. In your personal relationships, especially this evening, you will need to curb your natural tendency to obey orders. Chinese: Inscrutability has many advantages, but it may be your undoing today. British: Your stiff upper lip may serve you well in business dealings, but try to relax and let yourself go in your social life."

"The fact that something is written down is persuasive to people not used to asking questions like: ‘Who wrote it, and when?’ ‘How did they know what to write?’ ‘Did they, in their time really mean what we, in our time, understand them to be saying?’ ‘Were they unbiased observers, or did they have an agenda that coloured their writing?’. (p. 118 of the Black Swan paperback edition of 2007)"

""It is even possible to mount a serious, though not widely supported, historical case that Jesus never lived at all … Although Jesus probably existed, reputable biblical scholars do not in general regard the New Testament (and obviously not the Old Testament) as reliable record of what actually happened in history, and I shall not consider the Bible further evidence for any kind of deity." (p. 122)"

"[...] one of the truly bad effects of religion is that it teaches us that it is a virtue to be satisfied with not understanding. (p. 152 of the Black Swan paperback edition of 2007)"

"Natural selection builds child brains with a tendency to believe whatever their parents and tribal elders tell them. Such trusting obedience is valuable for survival: the analogue of steering by the moon for a moth. But the flip side of trusting obedience is slavish gullibility. The inevitable by-product is vulnerability to infection by mind viruses. (p. 176)"

"There is something infantile in the presumption that somebody else (parents in the case of children, God in the case of adults) has a responsibility to give your life meaning and point. [...] The truly adult view, by contrast, is that our life is as meaningful, as full and as wonderful as we choose to make it. And we can make it very wonderful indeed."

"Science replaces private prejudice with publicly verifiable evidence."

"Isn't Deepak Chopra just exploiting Quantum jargon as plausible-sounding hocus pocus?"

"The idea that ancient equal years of accumulated wisdom is a fallacy. [...] In medicine, 'ancient' also means developed before we understood the causes of disease, before germ theory. It was based on ignorance then and age makes it no truer. We misguidedly look back to a golden age that never was; ours is the golden age of safe tested medicine, effective beyond placebo, in which we've cut infant mortality and conquered diseases, then forgotten they existed."

"Sceptical rational inquiry is always the best approach. [...] we can think independently, be truly open-minded. That means asking questions, being open to real corroborated evidence. Reason has liberated us form superstition and given us centuries of progress. We abandon it at our peril."

"Ingenious? Yes. And scrupulous. Really good scientists have to be both."

"We don't need fossils – the case for evolution is watertight without them; so it is paradoxical to use gaps in the fossil record as though they were evidence against evolution"

"We're too stupid to decide on EU (that includes me)"

"I think there really is a place for science in literature and I think that may be increasing"

"(Spectrum level 6) I cannot know for certain but I think God is very improbable, and I live my life on the assumption that he is not there. (p. 73)"

"Admittedly, people of a theological bent are often chronically incapable of distinguishing what is true from what they'd like to be true. (p. 135 of the Black Swan paperback edition of 2007)"

"Thus the creationist's favourite question "What is the use of half an eye?" Actually, this is a lightweight question, a doddle to answer. Half an eye is just 1 per cent better than 49 per cent of an eye."

"I was reminded of a quotation by the famous American physicist Steven Weinberg, Nobel Prize-winning theoretical physicist. Weinberg said: "Religion is an insult to human dignity. Without it, you'd have good people doing good things, and evil people doing evil things. But for good people to do evil things, it takes religion". (Part 2, 00:35:01)"

"Pantheism is sexed-up atheism. Deism is watered-down theism. (p. 40)"

"I am not attacking any particular version of God or gods. I am attacking God, all gods, anything and everything supernatural, wherever and whenever they have been or will be invented. (p. 57 of the Black Swan paperback edition of 2007)"

"What expertise can theologians bring to deep cosmological questions that scientists cannot? (p. 79)"

"On the Argument from Degree: "That's an argument? You might as well say, people vary in smelliness but we can make the comparison only by reference to a perfect maximum of conceivable smelliness. Therefore there must exist a pre-eminently peerless stinker, and we call him God. Or substitute any dimension of comparison you like, and derive an equivalently fatuous conclusion." (p. 102)"

""But there are many unsophisticated Christians out there … who take the Bible very seriously indeed as a literal and accurate record of history and hence as evidence supporting the religious beliefs. Do these people never open the book that they believe is the literal truth? Why don't they notice the glaring contradictions?" (p. 120)"

""The four Gospels that made it into the official canon were chosen, more or less arbitrarily, out of a larger sample of at least a dozen … The gospels that didn't make it were omitted by those ecclesiastics perhaps because they included stories that were even more embarrassingly implausible than those in the four canonical ones." (p. 121)"

""However statistically improbable the entity you seek to explain by invoking a designer, the designer himself has got to be at least as improbable. God is the Ultimate Boeing 747" (p. 138)"

"On natural selection: "Any entity capable of intelligently designing something as improbable as Dutchman's Pipe (or a universe) would have to be even more improbable than a Dutchman's Pipe. Far from terminating the vicious regress, God aggravates it with a vengeance." (p. 146)"

""A God capable of continuously monitoring and controlling the individual status of every particle in the universe cannot be simple. His existence is going to need a mammoth explanation in its own right." (p. 178)"

"On the properties of God: "Such a bandwidth! God, who may not have a brain made of neurons, or a CPU made of silicon, but if he has the powers attributed to him he must have something far more elaborately and non-randomly constructed than the largest brain or the largest computer we know." (p. 184)"

""Once again, modern theologians will protest that the story of Abraham sacrificing Isaac should not be taken as literal fact. And, once again, the appropriate response is twofold. First, many many people, even to this day, do take the whole of their scripture to be literal fact, and they have a great deal of political power over the rest of us, especially in the United States and in the Islamic world. Second, if not as literal fact, how should we take the story? As an allegory? Then an allegory for what? Surely morals could one derive from this appalling story? Remember, all I am trying to establish for the moment is that we do not, as a matter of fact, derive our morals from scripture. Or, if we do, we pick and choose among the scriptures for the nice bits and reject the nasty. But then we must have some independent criterion for deciding which are the moral bits: a criterion which, wherever it comes from, cannot come from scripture itself and is presumably available to all of us whether we are religious or not. (p. 275 of the Black Swan paperback edition of 2007)"

"More generally (and this applies to Christianity no less than to Islam), what is really pernicious is the practice of teaching children that faith itself is a virtue. Faith is an evil precisely because it requires no justification and brooks no argument. Teaching children that unquestioned faith is a virtue primes them - given certain other ingredients that are not hard to come by - to grow up into potentially lethal weapons for future jihads or crusades. (pp. 347-348 of the Black Swan paperback edition of 2007)"

"Reason has built the modern world. It is a precious but also a fragile thing, which can be corroded by apparently harmless irrationality. We must favor verifiable evidence over private feeling. Otherwise we leave ourselves vulnerable to those who would obscure the truth."

"We should be open-minded, but not so open-minded that our brain falls out."

"So whereabouts in my body might there be a black hole?"

"To an atheist [...], there is no all-seeing all-loving god to keep us free from harm. But atheism is not a recipe for despair. I think the opposite. By disclaiming the idea of the next life, we can take more excitement in this one. The here and now is not something to be endured before eternal bliss or damnation. The here and now is all we have, an inspiration to make the most of it. So atheism is life-affirming, in a way religion can never be. Look around you. Nature demands our attention, begs us to explore, to question. Religion can provide only facile, ultimately unsatisfying answers. Science, in constantly seeking real explanations, reveals the true majesty of our world in all its complexity. People sometimes say "There must be more than just this world, than just this life". But how much more do you want? We are going to die, and that makes us the lucky ones. Most people are never going to die because they're never going to be born. The number of people who could be here, in my place, outnumber the sand grains of Sahara. If you think about all the different ways in which our genes could be permuted, you and I are quite grotesquely lucky to be here, the number of events that had to happen in order for you to exist, in order for me to exist. We are privileged to be alive and we should make the most of our time on this world."
