This book taps the best American thinkers to answer the essential American question: How do we sustain our experiment in government of, by, and for the people? Authored by an extraordinary and politically diverse roster of public officials, scholars, and educators, these chapters describe our nation's civic education problem, assess its causes, offer an agenda for reform, and explain the high stakes at risk if we fail.

It has been proposed by Dawkins, Dennett and others that memes are the units of cultural evolution. We here concentrate on Dennett's account because of the role it plays in his explanation of human consciousness - which is our principal target. Memes are claimed to be replicators that work on Darwinian principles. But in what sense are they replicators, and in what way are they responsible for their own propagation? We argue that their ability to replicate themselves is severely limited, (...) particularly in the case of language-borne memes. We contend, too, that the theory has unacceptable consequences for the role of design in accounting for cultural change, unless we seriously want to entertain the thought that design has as little relevance to cultural evolution as it does to the evolution of species. Finally, we argue that the account fails to do justice to the complexities of social practices. (shrink)

It is common in the history of science to try to extend an idea first demonstrated in one domain into others. Sometimes the extension is literal, and sometimes it is frankly metaphorical. Sometimes, however, when an extension is claimed to be literal, it is far from easy to see that it is. If an extension does not make use of entities and mechanisms involved in the original domain, and introduces novel entities and mechanisms, then it is not unreasonable to doubt (...) the claim of its authors that it is a literal extension of a well-established theory. IT is, therefore, not surprising that many who accept that the cultural transmission of information is unique to out species nevertheless balk at Dawkins's and Dennett's contention that there are units of cultural evolution, called 'memes', which can be used to explain the development and diversity of human culture, and whose survival is explicable in terms of Darwin's theory of evolution by natural selection. Our aim in this paper is to argue that scepticism about Dawkins's and Dennett's proposal is indeed justified; though it of course does not follow that there is not another way of explaining human culture in evolutionary terms.
