    Hi, Keith.

    Let's say you come down with a cold. Three weeks later you're infected with the exact same rhinovirus that got you before. Now that your immune system recognizes this particular virus, it quickly disposes of the germ before any harm is done. Let's say you were in favor of the war against Vietnam. By the time it was over you had learned your lesson. Thirty years later you were opposed to another aggressive war before the first shot was even fired.

    If you're immune to national narcissism, the memes that carry its message can't infect you.

    Again, you have to be willing to let the virus in. If you think that by opening an attachment to an email you will win a fabulous prize, then the virus will gain power over your computer. The perversion lies in the person who lets the virus in (and the person who created it) not the virus itself, which simply does its job.

    Genes are self-promoting, and so are memes.

    My understanding is that memetics is intended to provide a scientific account of human culture. I think it can indeed do so but only in the context of psychology, including group psychology.

    Not being a genetic reductionist, I can't agree with this.

    The difference is that a radioactive particle is guaranteed to degrade by half in a certain amount of time, whereas a meme's duration is open-ended.

    We don't need the memetics model to account for the recognition that ulcers are caused by bacteria. Someone had an idea, which he or she communicated to someone else. Since the idea turned out to be true, now lots of people believe it. No need for "selfish" units of culture propagating themselves. But the prior belief-- that ulcers are caused by stress-- is not only false but harmful. The extreme difficulty of uprooting this belief can be ascribed to the autonomy and resilience of the belief itself. Of course, if bad ideas are memes, then every idea is potentially memetic. That the bacterial explanation of ulcers is a meme can only be demonstrated indirectly.
