Quotes from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“There is no such thing as philosophy-free science; there is only science whose philosophical baggage is taken on board without examination.
—Daniel Dennett, Darwin's Dangerous Idea, 1995”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“But if it is true that human minds are themselves to a very great degree the creations of memes, then we cannot sustain the polarity of vision we considered earlier; it cannot be "memes versus us," because earlier infestations of memes have already played a major role in determining who or what we are. The "independent" mind struggling to protect itself from alien and dangerous memes is a myth. There is a persisting tension between the biological imperative of our genes on the one hand and the cultural imperatives of our memes on the other, but we would be foolish to "side with" our genes; that would be to commit the most egregious error of pop sociobiology. Besides, as we have already noted, what makes us special is that we, alone among species, can rise above the imperatives of our genes— thanks to the lifting cranes of our memes.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“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, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Problems in science are sometimes made easier by adding complications.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“I'm the guy who reputedly denies that people experience colors or pains, and thinks that thermostats think — just ask my critics.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“The fundamental core of contemporary Darwinism, the theory of DNA-based reproduction and evolution, is now beyond dispute among scientists. It demonstrates its power every day, contributing crucially to the explanation of planet-sized facts of geology and meteorology, through middle-sized facts of ecology and agronomy, down to the latest microscopic facts of genetic engineering. It unifies all of biology and the history of our planet into a single grand story. Like Gulliver tied down in Lilliput, it is unbudgeable, not because of some one or two huge chains of argument that might–hope against hope–have weak links in them, but because it is securely tied by hundreds of thousands of threads of evidence anchoring it to virtually every other field of knowledge. New discoveries may conceivably lead to dramatic, even 'revolutionary' shifts in the Darwinian theory, but the hope that it will be 'refuted' by some shattering breakthrough is about as reasonable as the hope that we will return to a geocentric vision and discard Copernicus.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Science, however, is not just a matter of making mistakes, but of making mistakes in public. Making mistakes for all to see, in the hopes of getting the others to help with the corrections.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Does that mean that religious texts are worthless as guides to ethics? Of course not. They are magnificent sources of insight into human nature, and into the possibilities of ethical codes. Just as we should not be surprised to discover that ancient folk medicine has a great deal to teach modern hightech medicine, we should not be surprised if we find that these great religious texts hold versions of the very best ethical systems any human culture will ever devise. But, like folk medicine, we should test it all carefully, and take nothing whatever on faith.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“There is no future in a sacred myth. Why not? Because of our curiosity. (...) Whatever we hold precious, we cannot protect it from our curiosity, because being who we are, one of the things we deem precious is the truth.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“It is not “scientism” to concede the objectivity and precision of good science, any more than it is history worship to concede that Napoleon did once rule in’ France and the Holocaust actually happened. Those who fear the facts will forever try to discredit the fact-finders.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“human beings are actually more closely related to the two species of chimpanzees (Pan troglodytes, the familiar chimp, and Pan paniscus, the rare, smaller pygmy chimp or bonobo) than those chimpanzees are to the other apes.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“[...] нормалното положение на нещата за всяка живо същество, което се размножава, е такова, че при всяко поколение се ражда по-многобройно потомство, отколкото е възможно да се възпроизведе. Иначе казано, ножът почти винаги е опрян до кокала.

Познат пример за действието на правилото на Малтус е размножаването на популация от дрожди в парче тесто или гроздов сок. Благодарение на изобилието от захари и други хранителни вещества следва популационна експлозия, която при тестото продължава в продължение на няколко часа, а при сока - няколко седмици. Рано или късно обаче популацията достига описания от Малтус тава в резултат от собствената си ненаситност и натрупването на отпадъчни продукти - въглероден двуокис (благодарение на който се появяват мехурчетата при втасването на хляба или в шампанското) и алкохол, които ние харесваме - за разлика от горките дрожди.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“As Dawkins goes on to say (p. 316), “The one thing that makes evolution such a neat theory is that it explains how organized complexity can arise out of primeval simplicity.” This is one of the key strengths of Darwin’s idea, and the key weakness of the alternatives. In fact, I once argued, it is unlikely that any other theory could have this strength:”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Americans are notoriously ill-informed about evolution. A recent Gallup poll (June 1993) discovered that 47 percent of adult Americans believe that Homo sapiens is a species created by God less than ten thousand years ago.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“[T]he idea of treating Mind as an effect rather than as a First Cause is too revolutionary for some–an "awful stretcher" that their own minds cannot acommodate comfortably. This is as true today as it was in 1860, and it has always been as true of some of evolution's best friends as of its foes. For instance, the physicist Paul Davies, in his recent book The Mind of God, proclaims that the reflective power of human minds can be "no trivial detail, no minor by-product of mindless purposeless forces" (Davies 1992, p. 232). This is a most revealing way of expressing a familiar denial, for it betrays an ill-examined prejudice. Why, we might ask Davies, would its being a by-product of mindless, purposeless forces make it trivial? Why couldn't the most important thing of all be something that arose from unimportant things? Why should the importance or excellence of anything have to rain down on it from on high, from something more important, a gift from God? Darwin's inversion suggests that we abandon that presumption and look for sorts of excellence, of worth and purpose, that can emerge, bubbling up out of "mindless, purposeless forces.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Ignorance is a necessary condition for many excellent things.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“We can now expose perhaps the most common misunderstanding of Darwinism: the idea that Darwin showed that evolution by natural selection is a procedure for producing Us. Ever since Darwin proposed his theory, people have often misguidedly tried to interpret it as showing that we are the destination, the goal, the point of all that winnowing and competition, and our arrival on the scene was guaranteed by the mere holding of the tournament. This confusion has been fostered by evolution’s friends and foes alike, and it is parallel to the confusion of the coin-toss tournament winner who basks in the misconsidered glory of the idea that since the tournament had to have a winner, and since he is the winner, the tournament had to produce him as the winner. Evolution can be an algorithm, and evolution can have produced us by an algorithmic process, without its being true that evolution is an algorithm for producing us.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“So Paley was right in saying not just that Design was a wonderful thing to explain, but also that Design took Intelligence. All he missed—and Darwin provided—was the idea that this Intelligence could be broken into bits so tiny and stupid that they didn’t count as intelligence at all, and then distributed through space and time in a gigantic, connected network of algorithmic process.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“But unless dualism or vitalism is true (in which case you have some extra, secret ingredient in you), you are made of robots—or what comes to the same thing, a collection of trillions of macromolecular machines. And all of these are ultimately descended from the original macros. So something made of robots can exhibit genuine consciousness, or genuine intentionality, because you do if anything does.”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Take, for instance, the possible fat man in that doorway; and, again, the possible bald man in that doorway. Are they the same possible man, or two possible men? How do we decide? How many possible men are there in that doorway? Are there more possible thin ones than fat ones? How many of them are alike? Or would their being alike make them one? Are no two possible things alike? Is this the same as saying that it is impossible for two things to be alike? Or, finally, is the concept of identity simply inapplicable to unactualized possibles? —WILLARD VAN ORMAN QUINE 1953, P. 4”
― Daniel C. Dennett, quote from Darwin's Dangerous Idea: Evolution and the Meanings of Life

“Where there's hope, there's life. It fills us with fresh courage and makes us strong again.”
― Anne Frank, quote from The Diary of a Young Girl

“How am I supposed to decide this? How can I possibly stay without mom and dad? How can I leave without Teddy? Or Adam? This is too much. I don’t even understand how it all works, why I’m here in the state that I’m in or how to get out of it if I wanted to. If I were to say, I want to wake up, would I wake up right now? I’ve already tried snapping my heels to find Teddy and tried to beam myself to Hawaii, and that didn’t work. This seems a whole lot more complicated.
But in spite of that, I believe it’s true. I hear the nurse’s words again. I am running the show. Everyone’s waiting on me.
I decide. I know this now.
And this terrifies me more than anything else that has happened today.”
― Gayle Forman, quote from If I Stay

“People love talking, and I have never been a huge talker. I carry on an inner monologue, but the words often don't reach my lips.”
― Gillian Flynn, quote from Gone Girl
