The whole idea of the ‘selfish gene’ is completely stupid, but such a clever way to befuddle stupid science groupies, with a clever weapon in the hands of economic ideologiets. This idea is one of cleverest swindles of the age of neoliberalism.
First, the hypostatization or anthropomorphism should be signal to change the terminology, at once. But its cleverness depends on that confusion.
Second, the idea is almsot certainly false, as science.
In terms of the critique of evolution we find in my discussions in WHEE we have the realization that ‘evolution’ at the macro level operates on a higher level than genetics. But even for reductionists, the idea is very dubious.
