Memes,like fitness, 'group selection' etc are an addition to a cluster of terms , that on closer inspection consists of a sophisticated restatement that what happens, happens.
Memes tautology Edit
"..The whiff of tautology is stronger in the concept of a meme. The closest I get to understanding the memetic replicator is that humans have a deeply embedded inclination to imitate. Well, yes. So viral messages ‘go viral’ because they have something which triggers the imitative response...."
Dawkins's "memetic theory of religion" is a classic example of the nonsense that is spawned when Darwinian thinking is applied outside its proper sphere. Along with Dennett, who also holds to a version of the theory, Dawkins maintains that religious ideas survive because they would be able to survive in any "meme pool", or else because they are part of a "memeplex" that includes similar memes, such as the idea that, if you die as a martyr, you will enjoy 72 virgins. Unfortunately, the theory of memes is science only in the sense that Intelligent Design is science. Strictly speaking, it is not even a theory. Talk of memes is just the latest in a succession of ill-judged Darwinian metaphors. Dawkins compares religion to a virus: religious ideas are memes that infect vulnerable minds, especially those of children. Biological metaphors may have their uses - the minds of evangelical atheists seem particularly prone to infection by religious memes, for example. At the same time, analogies of this kind are fraught with peril. Dawkins makes much of the oppression perpetrated by religion, which is real enough. He gives less attention to the fact that some of the worst atrocities of modern times were committed by regimes that claimed scientific sanction for their crimes. Nazi "scientific racism" and Soviet "dialectical materialism" reduced the unfathomable complexity of human lives to the deadly simplicity of a scientific formula. In each case, the science was bogus, but it was accepted as genuine at the time, and not only in the regimes in question. Science is as liable to be used for inhumane purposes as any other human institution. Indeed, given the enormous authority science enjoys, the risk of it being used in this way is greater." I hope to get around to making the odd comment myself in the next few days but I'm too tired now.
