In the beginning, there were no reasons; there were only causes. Nothing had a purpose, nothing has so much as a function; there was no teleology in the world at all.

Daniel Dennett
Highly technical philosophical arguments of the sort many philosophers favor are absent here. That is because I have a prior problem to deal with. I have learned that arguments, no matter how watertight, often fall on deaf ears. I am myself the author of arguments that I consider rigorous and unanswerable but that are often not such much rebutted or even dismissed as simply ignored.

Daniel Dennett
The task of the mind is to produce future, as the poet Paul Valéry once put it. A mind is fundamentally an anticipator, an expectation-generator. It mines the present for clues, which it refines with the help of the materials it has saved from the past, turning them into anticipations of the future. And then it acts, rationally, on the basis of those hard-won anticipations.

Daniel Dennett
But if we ask where precisely in the brain that point of view is located, the simple assumptions that work so well on larger scales of space and time break down. It is now quite clear that there is no single point in the brain where all information funnels in, and this fact has some far from obvious consequences.

Daniel Dennett
The salmon swimming upstream to spawn may be wily in a hundred ways, but she cannot even contemplate the prospect of abandoning her reproductive project and deciding instead to live out her days studying coastal geography or trying to learn Portuguese. The creation of a panoply of new standpoints is, to my mind, the most striking product of the euprimatic revolution.

Daniel Dennett
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.

Daniel Dennett
Evolution is all about processes that almost never happen. Every birth in every lineage is a potential speciation event, but speciation almost never happens, not once in a million births. Mutation in DNA almost never happens — not once in a trillion copings — but evolution depends on it. Take the set of infrequent accidents — things that almost never happen — and sort them into the happy accidents, the neutral accidents, and the fatal accidents; amplify the effects of the happy accidents — which happens automatically when you have replication and competition — and you get evolution.

Daniel Dennett
But I also can't prove that mushrooms could not be intergalactic spaceships spying on us.

Daniel Dennett
In spite of ferocious differences of opinion about other moral issues, there seems to be something approaching consensus that it is cruel and malicious to interfere with the life-enhancing illusions of others —unless those illusions are themselves the cause of of even greater ills. The disagreements come over what these greater ills might be- and this has led to the break down of the whole rationale. Keeping secrets from people for their own good can often be wise, but it takes only one person to give away a secret, and since there are disagreements about which cases warrant discretion, the result is an unsavory miasma of hypocrisy, lies, and frantic but fruitless attempts at distraction.

Daniel Dennett
We used to think that secrecy was perhaps the greatest enemy of democracy, and as long as there was no suppression or censorship, people could be trusted to make the informed decisions that would preserve our free society, but we have learned in recent years that the techniques of misinformation and misdirection have become so refined that, even in an open society, a cleverly directed flood of misinformation can overwhelm the truth, even though the truth is out there, uncensored, quietly available to anyone who can find it.

Daniel Dennett
In fact, if you are faced with the prospect of running across an open field in which lightning bolts are going to be a problem, you are much better off if their timing and location are determined by something, since then they may be predictable by you, and hence avoidable. Determinism is the friend, not the foe, of those who dislike inevitability.

Daniel Dennett
Thanks to technology, what almost anybody can do has been multiplied a thousandfold, and our moral understanding about what we ought to do hasn't kept pace.

Daniel Dennett
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.

Daniel Dennett
A prosthetically enhanced imagination is still liable to failure, especially if it is not used with sufficient rigor.

Daniel Dennett
Philosophers are never quite sure what they are talking about — about what the issues really are — and so often it takes them rather a long time to recognize that someone with a somewhat different approach (or destination, or starting point) is making a contribution.

Daniel Dennett
Philosophers might care to ask themselves … how often they are accomplices in increasing the audience for a second-rate article simply because their introductory course needs a simple-minded version of a bad idea that even freshmen can refute. Some of the most frequently reprinted articles in twentieth-century philosophy are famous precisely because nobody believes them; everybody can see what's wrong with them. … The confirmation of this claim is left as an exercise for the reader. Among the memes that structure the infosphere and hence affect the transmission of other memes are the laws of libel.

Daniel Dennett
It makes little difference where we draw the line between the pruning and shaping [of behavior] by natural selection which is genetically transmitted to offspring (the wiring you are born with), and the pruning and shaping that later takes place in the individual (the rewiring you end up with, as a result of experience or training). Nature and nurture blend seamlessly together.

Daniel Dennett
I am a philosopher, not a scientist, and we philosophers are better at questions than answers.

Daniel Dennett
Not a single one of the cells that compose you knows who you are, or cares.

Daniel Dennett
Problems in science are sometimes made easier by adding complications.

Daniel Dennett
The earth has grown a nervous system, and it's us.

Daniel Dennett
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.

Daniel Dennett
Minds are in limited supply, and each mind has a limited capacity for memes, and hence there is considerable competition among memes for entry in as many minds as possible.

Daniel Dennett
If you have ever asked yourself if there are facts about yourself (about your health, your competence, your prospects) you would rather not know, and decided that there were, you should be prepared to consider seriously the suggestion that the best — perhaps the only — way to ensure that such facts are not imposed on people is by prohibiting investigations likely to discover them.

Daniel Dennett
The theoretical fruits of deliberate oversimplification through idealization are not to be denied... Reality in all its messy particularity is too complicated to theorize about, taken straight. The issue is, rather (since every idealization is a strategic choice), which idealizations might really shed some light... which will just land us... diverting fairy tales.
