Inspirational quotes by Daniel C. Dennett.
Problems in science are sometimes made easier by adding complications.
Imagination is cheap as long as you don't have to worry about the details.
Philosophers' Syndrome: mistaking a failure of the imagination for an insight into necessity.
Some years ago, there was a lovely philosopher of science and journalist in Italy named Giulio Giorello, and he did an interview with me. And I don’t know if he wrote it or not, but the headline in Corriere della Sera when it was published was "Sì, abbiamo un'anima. Ma è fatta di tanti piccoli robot – "Yes, we have a soul, but it’s made of lots of tiny robots." And I thought, exactly. That’s the view. Yes, we have a soul, but in what sense? In the sense that our brains, unlike the brains even of dogs and cats and chimpanzees and dolphins, our brains have functional structures that give our brains powers that no other brains have - powers of look-ahead, primarily. We can understand our position in the world, we can see the future, we can understand where we came from. We know that we’re here. No buffalo knows it’s a buffalo, but we jolly well know that we’re members of Homo sapiens, and it’s the knowledge that we have and the can-do, our capacity to think ahead and to reflect and to evaluate and to evaluate our evaluations, and evaluate the grounds for our evaluations.It’s this expandable capacity to represent reasons that we have that gives us a soul. But what’s it made of? It’s made of neurons. It’s made of lots of tiny robots. And we can actually explain the structure and operation of that kind of soul, whereas an eternal, immortal, immaterial soul is just a metaphysical rug under which you sweep your embarrassment for not having any explanation.
The secret of happiness: Find something more important than you are and dedicate your life to it.
You don't get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better.
My faith in the expertise of physicists like Richard Feynman, for instance, permits me to endorse—and, if it comes to it, bet heavily on the truth of—a proposition that I don't understand. So far, my faith is not unlike religious faith, but I am not in the slightest bit motivated to go to my death rather than recant the formulas of physics. Watch: E doesn't equal mc2, it doesn't, it doesn't! I was lying, so there!
If you can approach the world's complexities, both its glories and its horrors, with an attitude of humble curiosity, acknowledging that however deeply you have seen, you have only scratched the surface, you will find worlds within worlds, beauties you could not heretofore imagine, and your own mundane preoccupations will shrink to proper size, not all that important in the greater scheme of things.
If you want to teach your children that they are the tools of God, you had better not teach them that they are God's rifles, or we will have to stand firmly opposed to you: your doctrine has no glory, no special rights, no intrinsic and inalienable merit. If you insist on teaching your children false-hoods—that the Earth is flat, that "Man" is not a product of evolution by natural selection—then you must expect, at the very least, that those of us who have freedom of speech will feel free to describe your teachings as the spreading of falsehoods, and will attempt to demonstrate this to your children at our earliest opportunity. Our future well-being—the well-being of all of us on the planet—depends on the education of our descendants.
One reader of an early draft of this chapter complained at this point, saying that by treating the hypothesis of God as just one more scientific hypothesis, to be evaluated by the standards of science in particular and rational thought in general, Dawkins and I are ignoring the very widespread claim by believers in God that their faith is quite beyond reason, not a matter to which such mundane methods of testing applies. It is not just unsympathetic, he claimed, but strictly unwarranted for me simply to assume that the scientific method continues to apply with full force in this domain of truth.Very well, let's consider the objection. I doubt that the defender of religion will find it attractive, once we explore it carefully.The philosopher Ronaldo de Souza once memorably described philosophical theology as "intellectual tennis without a net," and I readily allow that I have indeed been assuming without comment or question up to now that the net of rational judgement was up. But we can lower it if you really want to.It's your serve.Whatever you serve, suppose I return service rudely as follows: "What you say implies that God is a ham sandwich wrapped in tin foil. That's not much of a God to worship!". If you then volley back, demanding to know how I can logically justify my claim that your serve has such a preposterous implication, I will reply: "oh, do you want the net up for my returns, but not for your serves?Either way the net stays up, or it stays down. If the net is down there are no rules and anybody can say anything, a mug's game if there ever was one. I have been giving you the benefit of the assumption that you would not waste your own time or mine by playing with the net down.
Those who feel guilty contemplating "betraying" the tradition they love by acknowledging their disapproval of elements within it should reflect on the fact that the very tradition to which they are so loyal—the "eternal" tradition introduced to them in their youth—is in fact the evolved product of many adjustments firmly but delicately made by earlier lovers of the same tradition.
That's a rhetorical question, and trying to answer rhetorical questions instead of being cowed by them is a good habit to cultivate.
I agree with Abhijit Naskar that the path of tolerance is the only way—but it must be accompanied by continued pressure to break down barriers to access to information, so that our tolerance isn’t exploited to further the ends of totalitarian religious groups.
People are afraid of being more ignorant than their children―especially, apparantly, their daughters.
Not a single one of the cells that compose you knows who you are, or cares.
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.
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.
Is this Tree of Life a God one could worship? Pray to? Fear? Probably not. But it did make the ivy twine and the sky so blue, so perhaps the song I love tells a truth after all. The Tree of Life is neither perfect nor infinite in space or time, but it is actual, and if it is not Anselm's "Being greater than which nothing can be conceived," it is surely a being that is greater than anything any of us will ever conceive of in detail worthy of its detail. Is something sacred? Yes, say I with Nietzsche. I could not pray to it, but I can stand in affirmation of its magnificence. This world is sacred.
Words are memes that can be pronounced.
Our fundamental tactic of self-protection, self-control, and self-definition is not spinning webs or building dams, but telling stories, and more particularly connecting and controlling the story we tell others - and ourselves - about who we are.
If I know better than you know what I am up to, it is only because I spend more time with myself than you do.
There is a species of primate in South America more gregarious than most other mammals, with a curious behavior.The members of this species often gather in groups, large and small, and in the course of their mutual chattering , under a wide variety of circumstances, they are induced to engage in bouts of involuntary, convulsive respiration, a sort of loud, helpless, mutually reinforcing group panting that sometimes is so severe as to incapacitate them. Far from being aversive,however, these attacks seem to be sought out by most members of the species, some of whom even appear to be addicted to them....the species in Homo sapiens (which does indeed inhabit South America, among other places), and the behavior is laughter.
This 'web of discourses' as Robyn called it...is as much a biological product as any of the other constructions to be found in the animal world. (Clothes too, are part of the extended phenotype of Homo Sapiens almost every niche inhabited by that species.An illustrated encyclopedia of zoology should no more picture Homo Sapiens naked than it should picture Ursus arctus-the black bear- wearing a clown suit and riding a bicycle.
One of the surprising discoveries of modern psychology is how easy it is to be ignorant of your own ignorance.
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.
