Your discussion of memes and culture is a fascinating one. Tell me, what do you think about the selfish-meme/selfish-gene latching onto character traits in individuals? What I mean is, could it be said that some people, for whatever reason, are more likely to be "procreators" of memes and by the same measure, uninterested or not likely to be procreators of genes. Can we find any examples of meme-spreader's on a huge scale who have, for social or psychological or even physiological reasons, have been poor gene procreators. Hitler, for example... Can we link any specific qualities in an individual that says they are more likely to be one and not the other, or proportionately, more of one and less of the other? Are the qualities which make an exceptional meme-spreader somehow non-conducive to gene-spreading? Is the intellectually driven person unlikely to engage so much in the physical world? I am posing questions here, not giving a whole theory. Would be glad to hear your ideas.
