    OK, sorry for taking the bee in my bonnet out on you (to mix a metaphor).

    I'm not sure memetics helps much in explaining any particular example.
    What does it tell us? Patterns in behaviour (and, therefore, in
    brains) that are good at survival via reproduction, go on surviving
    via reproduction. What makes them so good is something we have to go
    outside of memetics to see. The reason some short musical phrases act
    as terrific "hooks" is something I find intriguing, and the effects are
    classically memetic, but the causes are deep in the auditory-emotional
    wiring of the brain. This is exactly the same situation as for the
    principles of biological evolution: at its most basic, it is circular
    (though to understand it is STILL infinitely better than not to do so
    -- its circularity doesn't diminish that fact at all). But there seems
    to be much more to genetics than that, because the practical details of
    biological development are typically approached from a genetic point of
    view, whereas, for various reasons, the practical details of cultural
    development have in many cases been quite deeply gone into using other
    paradigms, so there isn't much left for memetics to do, apart from
    supplying the overarching theme, as in "Patterns in behaviour..."

    Sorry for the double negative. I'm actually saying exactly the opposite.

    Agreed.

    As I said, I don't see memetics providing specifics. Other disciplines
    are already too well-developed, so there's nothing left for memetics --
    at that level. For me, it's of purely theoretical interest. Was Dawkins
    correct _in_principle_ when he supposed that memes could explain all
    behaviour that genes cannot? That for me is the issue. In practice,
    it ain't gonna happen. Both because the calculations are far too
    complicated, even for quantum computing, and because there's no need,
    with all the other tools at our disposal. The combination of these two
    factors is, to my mind, absolutely insurmountable.

    There's more to life, and even to serious study, than science. Some
    extremely valuable developments are entirely conceptual, ie come under
    the remit of philosophy rather than science. Not everything is to be
    tested directly -- some things, that help us formulate testable theories,
    can themselves only be tested indirectly. Philosophy is a set of tools to
    help us formulate testable theories (and also, to some extent, to help us
    handle untestables, matters of opinion rather than fact, such as values).
