I think Daniel Dennett is right about the rise of religion in our species. Religious instincts are a feature of evolutionary memes and advantage of type 1 and type two errors.
I don't know if everyone is familiar with this theory that religion is a feature of evolutionary memes.
According to Dennett
the term «meme» is appropriate if it designates this set of adaptive resources of each species arising from the play of interactions between neural networks, mimesis and memory. Memes are already present in animal species and are proper to each species. However, they are also present in the human species. We have a legacy of genes which constitutes our basic biology, but we also have a legacy of memes which constitutes our culture. This is a structure of memes, forming coherent systems, which is inevitably transmitted (remember the memeplexes of Susan Blackmore). This is naturally open and never closed.
The idea is that
religion is a conduct produced by a memetic structure.
Daniel Dennett tells us that religion is a meme, it has a memetic structure. From here he reaches the surprising conclusion: religion is a natural phenomenon.
The structure of his book is very simple. Religion arose in primitive times due to irra- tional fear of the clamour and threats of nature. Thus, it was constituted as a meme which has been unceasingly replicated down to us.
Dennett insist that he only seeks the Darwinist analysis of religion from a point of view of evolutionary biology (we think he should rather say the evolutionary psycholo- gy of culture).
This raises several questions.
1. According to this theory it arises naturally due to neural networks, mimesis and memory. Why then have do we not see evidence of religion in any other species?
This theory does not explain why man alone has religion.
2. He is seeking a Darwinist analysis of religion. I suspect that this is referring to the theory of evolution, survival of the fittest, and that religion has somehow made man fitter. Yet his theory does not in any way explain how this has conferred an evolutionary advantage. Why say that it arose from "irrational fears" if it is conferring an evolutionary advantage? If it is not conferring an evolutionary advantage then how is this a Darwinist analysis of religion?
Consider this in the context of this thread. What other species has "public policy"? What other species would ask if religious belief should inform public policy? There are millions of species, if religion is a natural process that results because of neuronal networks why is it we don't see evidence of that in any other species?
The entire theory of evolution is based on the idea of "random mutations", similar to the flip of a dice. Given enough flips any and all variations will appear. Yet this variation has not appeared in anyone but man, and yet it appears in every human society on earth for all human history. The odds are trillions to 1.
A memeplex replicates "virally" according to Dennett. A virus is not part of our DNA. According to this theory religion is like a virus that has infected all of mankind. It is truly extraordinary to have a virus that has so thoroughly infected a single species for so long. It may seem less extraordinary now that we have Globalization, but ten thousand years ago many of these societies did not have any interaction with each other and yet they were all thoroughly infected. Another extraordinary thing about this "virus" is that it has not jumped to another species. A virus the infects our cattle will jump to humans, a virus that infects our poultry will jump to humans, why is it that the virus that infects the humans doesn't jump to any of these species we have been so close to?
So according to Dennett it acts like a virus, only it doesn't, at least not like any other virus we are familiar with. It acts according to Darwin's theory of evolution only it doesn't. Unlike that theory the survival of this trait is not due to any evolutionary advantage. According to Dennett it is due to a natural phenomenon in neural networks common to many other species, only it isn't. We don't see this phenomenon in any other species.
As a result many consider his theory to be pseudo science lacking in basis (Alister McGrath, Oxford), or false scientificism (Leon Wieseltier, NY Times book review).
