Daniel C. Dennett


Prominent American philosopher.
Daniel C. Dennett
Are zombies possible? They're not just possible, they're actual. We're all zombies. Nobody is conscious — not in the systematically mysterious way that supports such doctrines as epiphenomenalism.
Dennett quotes
[A] skyhook is ... an exception to the principle that all design, and apparent design, is ultimately the result of mindless, motiveless mechanicity. A crane, in contrast, is a subprocess or special feature of a design process that can be demonstrated to permit the local speeding up of the basic, slow process of natural selection, and that can be demonstrated to be itself the predictable (or retroactively explicable) product of the basic process. ... [T]he physicist Steven Weinberg, in Dreams of a Final Theory (1992) ... distinguishes between uncompromising reductionism (a bad thing) and compromising reductionism (which he ringingly endorses). Here is my own version. We must distinguish reductionism, which is in general a good thing, from greedy reductionism, which is not. The difference, in the context of Darwin's theory, is simple: greedy reductionists think that everything can be explained without cranes; good reductionists think that everything can be explained without skyhooks.
Dennett
It is commonly observed - but not commonly enough! - that old folks removed from their homes to hospital settings are put at a tremendous disadvantage, even though their basic bodily needs are well provided for. They often appear to be quite demented - to be utterly incapable of feeding, clothing, and washing themselves, let alone engaging in any activities of greater interest. Often, however, if they are returned to their homes, they can manage quite well for themselves. How do they do this? Over the years, they have loaded their home environments with ultrafamiliar landmarks, triggers for habits, reminder of what to do, where to find the food, how to get dressed, where the telephone is, and so forth. An old person can be a veritable virtuoso of self-help in such a hugely overlearned world, in spite of his or her brain's increasing imperviousness to new bouts of learning... Taking them out of their homes is literally separating them from large parts of their minds - potentially just as devastating a development as undergoing brain surgery.




Dennett Daniel C. quotes
Not a single one of the cells that compose you knows who you are, or cares.
Dennett Daniel C.
[L]et your self go. 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. Keeping that awestruck vision of the world ready to hand while dealing with the demands of daily living is no easy exercise, but it is definitely worth the effort, for if you can stay centered, and engaged, you will find the hard choices easier, the right words will come to you when you need them, and you will be a better person. That, I propose, is the secret to spirituality, and it has nothing at all to do with believing in an immortal soul, or in anything supernatural.
Daniel C. Dennett quotes
Unpredictability is in general a fine protective feature, which should never be squandered but always spent wisely. There is much to be gained from communication if it is craftily doled out - enough truth to keep one's credibility high but enough falsehood to keep one's options open. (This is the first point of wisdom in the game of poker: he who never bluffs never wins; he who always bluffs always loses.)
Daniel C. Dennett
[T]he only meaning of life worth caring about is one that can withstand our best efforts to examine it.
Dennett Daniel C. quotes
Up till now [the development of proto-consciousness], we can suppose, nervous systems solved the "Now what do I do?" problem by a relatively simple balancing act between a strictly limited repertoire of actions - if not the famous four F's (fight, flee, feed, or mate), then a modest elaboration of them.
Dennett
People ache to believe that we human beings are vastly different from all other species - and they are right! We are different. We are the only species that has an extra medium of design preservation and design communication: culture. ... We have language, the primary medium of culture... In a few short millennia - a mere instant in biological time - we have already used our new exploration vehicles to transform not only our planet but the very process of design development that created us.
Dennett Daniel C.
Political correctness, in the extreme versions worthy of the name, is antithetical to almost all surprising advances in thought. We might call it eumemics, since it is, like the extreme eugenics of Social Darwinists, an attempt to impose myopically derived standards of safety and goodness on the bounty of nature. Few today - but there are a few - would brand all genetic counseling, all genetic policies, with the condemnatory title of eugenics.
Daniel C. Dennett
Much of the controversy and anxiety that has enveloped Darwin's idea ... can be understood as a series of failed campaigns to contain Darwin;s idea within some acceptably "safe" and merely partial revolution. Cede some or all of modern biology to Darwin, perhaps, but hold the line there! Keep Darwinian thinking out of cosmology, out of psychology, out of human culture, out of ethics, politics, and religion! In these campaigns, many battles have been won by the forces of containment: flawed applications of Darwin's idea have been exposed and discredited, beaten back by the champions of the pre-Darwinian tradition. But new waves of Darwinian thinking keep coming.




Daniel C. Dennett quotes
We live in a world that is subjectively open. And we are designed by evolution to be "informavores," epistemically hungry seekers of information, in an endless quest to improve our purchase on the world.
Daniel C. Dennett
Remember Marxism? It used to be a sour sort of fun to tease Marxists about the contradictions in some of their pet ideas. The revolution of the proletariat was inevitable, good Marxists believed, but if so, why were they so eager to enlist us in their cause? If it was going to happen anyway, it was going to happen with or without our help. But of course the inevitability that Marxists believe in is one that depends on the growth of the movement and all its political action. There were Marxists working very hard to bring about the revolution, and it was comforting to them to believe that their success was guaranteed in the long run. And some of them, the only ones that were really dangerous, believed so firmly in the rightness of their cause that they believed it was permissible to lie and deceive in order to further it. They even taught this to their children, from infancy. These are the "red-diaper babies," children of hardline members of the Communist Party of America, and some of them can still be found infecting the atmosphere of political action in left-wing circles, to the extreme frustration and annoyance of honest socialists and others on the left.
Dennett quotes
There is a familiar trio of reactions by scientists to a purportedly radical hypothesis: (a) "You must be out of your mind!", (b) "What else is new? Everybody knows that!", and, later - if the hypothesis is still standing - (c) "Hmm. You *might* be on to something!" Sometimes these phases take years to unfold, one after another, but I have seen all three emerge in near synchrony in the course of a half-hour's heated discussion following a conference paper.
Dennett Daniel C.
[T]here are no forces on this planet more dangerous to us all than the fanaticisms of fundamentalism, of all species: Protestantism, Catholicism, Judaism, Islam, Hinduism, and Buddhism, as well as countless smaller infections.
Dennett Daniel C. quotes
Evolution embodies information in every part of every organism. ... This information doesn't have to be copied into the brain at all. It doesn't have to be "represented" in "data structures" in the nervous system. It can be exploited by the nervous system, however, which is designed to rely on, or exploit, the information in the hormonal systems just as it is designed to rely on, or exploit, the information embodied in your limbs and eyes. So there is wisdom, particularly about preferences, embodied in the rest of the body. By using the old bodily systems as a sort of sounding board, or reactive audience, or critic, the central nervous system can be guided - sometimes nudged, sometimes slammed - into wise policies. Put it to the vote of the body, in effect. ...
Daniel C. Dennett
The distinction between responsible moral agents and beings with diminished or no responsibility is coherent, real, and important. It is coherent, even if in many instances it is hard to apply; it draws an empirically real line, in that we don't all fall on one side; and, most important, the distinction matters: the use we make of it plays a crucial role in the quality and meaning of our lives. [...] We want to hold ourselves and others responsible, but we recognize that our intuitions often support the judgement that a particular individual has "diminished responsibility" because of his or her infirmities, or because of particularly dire circumstances upon upbringing or at the time of action. We also find it plausible to judge that nonhuman animals, infants, and those who are severely handicapped mentally are not responsible at all. But since we are all more or less imperfect, will there be anyone left to be responsible after we have excused all those with good excuses? [...] We must set up some efficiently determinable threshold for legal competence, never for a moment supposing that there couldn't be intuitively persuasive "counterexamples" to whatever line we draw, but declaring in advance that such pleas will not be entertained. [...] The effect of such an institution [...] is to create [...] a class of legally culpable agents whose subsequent liability to punishment maintains the credibility of the sanctions of the laws. The institution, if it is to maintain itself, must provide for the fine tuning of its arbitrary thresholds as new information (or misinformation) emerges that might undercut its credibility. One can speculate that there is an optimal setting of the competence threshold (for any particular combination of social circumstances, degree of public sophistication, and so on) that maximizes the bracing effect of the law. A higher than optimal threshold would encourage a sort of malingering on the part of the defendants, which, if recognized by the populace, would diminish their respect for the law and hence diminish its deterrent effect. And a lower than optimal threshold would yield a diminishing return of deterrence and lead to the punishment of individuals who, in the eyes of society, "really couldn't help it." The public perception of the fairness of the law is a critical factor in its effectiveness.
Daniel C. Dennett quotes
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 C. Dennett
I think religion for many people is some sort of moral viagra.
Dennett Daniel C.
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.
