That is very, >very far from mainstream memetics. Hmm. I think that there is a lot of terminological confusion here :-) The serious papers that I have seen have used none of the above terms, and have actually not referred to the concepts directly. But they HAVE shown that they were using them. I was referring to the inheritance of intelligence (e.g. some papers in Nature) and similarly language and technological concepts. It is now generally accepted that such "taught inheritance" is very important in the higher mammals and probably as important as genetic inheritance in humans as far as brain function goes. 30+ years back, this was an extreme view. 100+ years back, it was heresy. I am not deeply into this area, so don't know what is currently held to be mainstream mimetics. But I am am afraid that I am increasingly disenchanted with the way that new terms are being created - often as a way of putting a coherence or importance on conglomerations of ideas that don't deserve it.

Yes, it IS testable :-) What is more, it explains certain observations that are simply denied by the establishment, despite the fact that they were accepted a while back. The issue lies a LOT deeper than mere description, whatever the truth of the matter is. I really do mean the theory that human belief can change the way that the universe behaves. Heaven alone knows whether there is anything in it, but I can think of ways to test it, though they are politically impracticable. And it is DEFINITELY heretical :-) >> Harking back to "memetics" - the invention of the term merely >> indicates that there is a new religion - I would not go so far as >> to claim that many people regard ideas as a form of life. > >Are genes a "form of life"? Not as I view it. But where the boundary comes, heaven alone knows. Viruses? Prions?
