"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. This competition is the major selective force in the memosphere, and, just as in the biosphere, the challenge has been met with great ingenuity. For instance, whatever virtues the following memes have, they have in common the property of having phenotypic expressions that tend to make their own replication more likely by disabling or preempting the environmental forces that would tend to extinguish them: the meme for faith, which discourages the exercise of the sort of critical judgment that might decide that the idea of faith was, all things considered a dangerous idea; the meme for tolerance or free speech; the meme of including in a chain letter a warning about the terrible fates of those who have broken the chain in the past; the conspiracy theory meme, which has a built-in response to the objection that there is no good evidence of a conspiracy: "Of course not — that's how powerful the conspiracy is!" Some of these memes are "good" perhaps and others "bad"; what they have in common is a phenotypic effect that systematically tends to disable the selective forces arrayed against them. Other things being equal, population memetics predicts that conspiracy theory memes will persist quite independently of their truth, and the meme for faith is apt to secure its own survival, and that of the religious memes that ride piggyback on it, in even the most rationalistic environments. Indeed, the meme for faith exhibits frequency-dependent fitness: it flourishes best when it is outnumbered by rationalistic memes; in an environment with few skeptics, the meme for faith tends to fade from disuse."

“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.”

“t makes little difference where we draw the line between the pruning and shaping by natural selection which is genetically transmitted to offspring , and the pruning and shaping that later takes place in the individual . Nature and nurture blend seamlessly together.”

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

“Philosophers' Syndrome: mistaking a failure of the imagination for an insight into necessity.”

“The first stable conclusion I reached … was that the only thing brains could do was to approximate the responsivity to meanings that we presuppose in our everyday mentalistic discourse. When mechanical push comes to shove, a brain was always going to do what it was caused to do by current, local, mechanical circumstances, whatever it ought to do, whatever a God's-eye view might reveal about the actual meaning of its current states. But over the long haul, brains could be designed – by evolutionary processes – to do the right thing with high reliability. … rains are syntactic engines that can mimic the competence of semantic engines. … The appreciation of meanings – their discrimination and delectation – is central to our vision of consciousness, but this conviction that I, on the inside, deal directly with meanings turns out to be something rather like a benign "user-illusion.”

“Since September 11, 2001, I have often thought that perhaps it was fortunate for the world that the attackers targeted the World Trade Center instead of the Statue of Liberty, for if they had destroyed our sacred symbol of democracy I fear we as Americans would have been unable to keep ourselves from indulging in paroxysms of revenge of a sort the world has never seen before. If that had happened, it would have befouled the meaning of the Statue of Liberty beyond any hope of subsequent redemption — if there were any people left to care. I have learned from my students that this upsetting thought of mine is subject to several unfortunate misconstruals, so let me expand on it to ward them off. The killing of thousands of innocents in the World Trade Center was a heinous crime, much more evil than the destruction of the Statue of Liberty would have been. And, yes, the World Trade Center was a much more appropriate symbol of al Qaeda's wrath than the Statue of Liberty would have been, but for that very reason it didn't mean as much, as a symbol, to us. It was Mammon and Plutocrats and Globalization, not Lady Liberty. I do suspect that the fury with which Americans would have responded to the unspeakable defilement of our cherished national symbol, the purest image of our aspirations as a democracy, would have made a sane and measured response extraordinarily difficult. This is the great danger of symbols — they can become too "sacred". An important task for religious people of all faiths in the twenty-first century will be spreading the conviction that there are no acts more dishonorable than harming "infidels" of one stripe or another for "disrespecting" a flag, a cross, a holy text.”
