Daniel C. Dennett Quotes & Sayings

Darwin's "strange inversion of reasoning" and Turing's equally revolutionary inversion were aspects of a single discovery: competence without comprehension. Comprehension, far from being a Godlike talent from which all design must flow, is an emergent effect of systems of uncomprehending competence: natural selection on the one hand, and mindless computation on the other. These twin ideas have been proven beyond a reasonable doubt, but they still provoke dismay and disbelief in some quarters, which I have tried to dispel in this chapter. Creationists are not going to find commented code in the inner workings of organisms, and Cartesians are not going to find an immaterial res cogitans "where all the understanding happens". — Daniel C. Dennett

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. — Daniel C. Dennett

Ancestor worship must be an appealing idea to those who are about to become ancestors. - Steven Pinker, How the Mind Works — Daniel C. Dennett

You can't change your beliefs as an act of will, in the way you can decide to improve your skills with chainsaw or keyboard. — Daniel C. Dennett

The mind is the effect, not the cause. — Daniel C. Dennett

As the comedian Emo Phillips once said, "When I was a child, I used to pray to God for a bicycle. But then I realized that God doesn't work in that way - so I stole a bike and prayed for forgiveness! — Daniel C. Dennett

prosaic, pedestrian example, but everything — Daniel C. Dennett

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

Like many other natural wonders, the human mind is something of a bag of tricks, cobbled together over the eons by the foresightless process of evolution by natural selection. — Daniel C. Dennett

Carpenters don't make their saws and hammers, tailors don't make their scissors and needles, and plumbers don't make their wrenches, but blacksmiths can make their hammers, tongs, anvils, and chisels — Daniel C. Dennett

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. — Daniel C. Dennett

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

Anything that is usefully and voluminously predictable from the intentional stance is, by definition, an intentional system, and as we shall see, many fascinating and complicated things that don't have brains or eyes or ears or hands, and hence really don't have minds, are nevertheless intentional systems. Folk psychology's basic trick, that is to say, has some bonus applications outside the world of human interactions. — Daniel C. Dennett

The more you have invested in your religion, the more you will be motivated to protect that investment. Stark — Daniel C. Dennett

It's not an intellectual exercise. It's not an academic pursuit - it sort of masquerades as one, but at its core it's a test of trust in each other. Are you or aren't you one of us? And woe to the one who doesn't toe the line. — Daniel C. Dennett

It is not enough to succeed. Others must fail. — Daniel C. Dennett

That's a rhetorical question, and trying to answer rhetorical questions instead of being cowed by them is a good habit to cultivate. — Daniel C. Dennett

There is only one way to respect the substance of any purported God-given moral edict: consider it conscientiously in the full light of reason, using all the evidence at our command. No God that was pleased by displays of unreasoning love would be worthy of worship. — Daniel C. Dennett

It turns out that all the "magic" of cognition depends, just as life itself does, on cycles within cycles of recurrent, "re-entrant," reflexive information-transformation processes — Daniel C. Dennett

Some of my scientific friends and colleagues confess that they cannot for the life of them see why I don't abandon ship and join them. The short answer is that I have managed, by straddling the boundaries, to have the best of both worlds. By working with scientists I get a rich diet of fascinating and problematic facts to think about, but by staying a philosopher without a lab or a research grant, I get to think about all the theories and experiments and never have to do the dishes — Daniel C. Dennett

Good people will do good things, and bad people will do bad things. But for good people to do bad things - that takes religion. - Steven Weinberg, 1999 — Daniel C. Dennett

One cannot learn all about what it's like to run a marathon by interviewing only those who drop out - but one can learn something. — Daniel C. Dennett

to compose a successful critical commentary: 1. You should attempt to re-express your target's position so clearly, vividly, and fairly that your target says, "Thanks, I wish I'd thought of putting it that way." 2. You should list any points of agreement (especially if they are not matters of general or widespread agreement). 3. You should mention anything you have learned from your target. 4. Only then are you permitted to say so much as a word of rebuttal or criticism. — Daniel C. Dennett

Words are memes that can be pronounced. — Daniel C. Dennett

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

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. — Daniel C. Dennett

A good library has all the good books. A great library has all the books. — Daniel C. Dennett

Some people would much prefer the infinite regress of mysteries, apparently, but in this day and age the cost is prohibitive: you have to get yourself deceived. You can either deceive yourself or let others do the dirty work, but there is no intellectually defensible way of rebuilding the mighty barriers to comprehension that Darwin smashed. (p.25) — Daniel C. Dennett

I didn't plan to become an atheist. I didn't even want to become an atheist. It's just that I had no choice. If I'm being honest with myself. — Daniel C. Dennett

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

These bizarre examples attempt to prove one conceptual point or another by deliberately reducing all but one underappreciated feature of some phenomenon to zero, so that what really counts can shine through. The twin earth example sets internal similarity to a maximum (you are whisked off to Twin Earth without being given a chance to register this huge shift) so that external context can be demonstrated to be responsible for whatever our intuition tells us. — Daniel C. Dennett

Religions exist primarily for people to achieve together what they cannot achieve alone. - David Sloan Wilson, Darwin's Cathedral — Daniel C. Dennett

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

It is worth recalling that it took brave pioneers many years to overcome the powerful taboo against the dissection of human cadavers during the early years of modern medicine. And we should note that, notwithstanding the outrage and revulsion with which the idea of dissection was then received, overcoming that tradition has not led to the feared collapse of morality and decency. We live in an era in which human corpses are still treated with due respect - indeed, with rather more respect and decorum than they were treated with at the time dissection was still disreputable. — Daniel C. Dennett

People who want to study religion usually have an ax to grind. They either want to defend their favorite religion from its critics or want to demonstrate the irrationality and futility of religion, and this tends to infect their methods with bias. — Daniel C. Dennett

One of the surprising discoveries of modern psychology is how easy it is to be ignorant of your own ignorance. — Daniel C. Dennett

This is natural selection, plain as day: the islanders have a simple rule: if it returns from the sea intact, copy it! They may have considerable comprehension of the principles of naval architecture that retrospectively endorse their favorite designs, but it is strictly unnecessary. — Daniel C. Dennett

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. — Daniel C. Dennett

A mountain climber foolishly climbing alone slips off a precipice and finds himself dangling at the end of his safety rope, a thousand feet above a ravine. Unable to climb the rope or swing to a safe resting spot, he calls out in despair: "Hallooo, hallooo! Can anybody help me?" To his astonishment, the clouds part, a beautiful light pours through them, and a mighty voice replies, "Yes, my son, I can help you. Take your knife and cut the rope!" The climber takes out his knife, and then he stops, and thinks and thinks. Then he cries out: "Can anybody else help me? — Daniel C. Dennett

We have all heard the forlorn refrain "Well, it seemed like a good idea at the time!" This phrase has come to stand for the rueful reflection of an idiot, a sign of stupidity, but in fact we should appreciate it as a pillar of wisdom. Any being, any agent, who can truly say, "Well, it seemed like a good idea at the time!" is standing on the threshold of brilliance. We — Daniel C. Dennett

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. — Daniel C. Dennett

Science properly done is one of the humanities, as a fine physics teacher once said. The point of science is to help us understand what we are and how we got here, and for this we need the great stories: the tale of how, once upon a time, there was a Big Bang; the Darwinian epic of the evolution of life on Earth; and now the story we are just beginning to learn how to tell... — Daniel C. Dennett

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

What you can imagine depends on what you know. — Daniel C. Dennett

Our manifest image, unlike the daisy's ontology or Umwelt, really is manifest, really is subjective in a strong sense. It's the world we live in, the world according to us. — Daniel C. Dennett

I think we should stop treating ["God works in mysterious ways"] as any kind of wisdom and recognize it as the transparently defensive propaganda that it is. A positive response might be, "Oh good! I love a mystery. Let's see if we can solve this one, too. Do you have any ideas? — Daniel C. Dennett

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
