    The unit of analysis is any belief or idea that spreads across a group. Let's take an example. I subscribe to a list devoted to the creation of a
    "standard upper ontology." For years the members of this list have talked about nothing but the creation of an ontology that can provide a common language for researchers in diverse fields. While they often drift somewhat into related philosophical discussion, one thing they've never done is to start talking politics.

    Until now. All of a sudden, they've been swept up in a discussion of Bush and the environment. It started when the first Mars rover landed. Someone thought it was neat and posted something about solving our population problem by colonizing Mars. Naturally, numerous people on the list were astounded that anyone could be so naive. Predictably, someone else remarked that we could hardly expect to terraform other planets when we can't even maintain a livable environment on this one. Pretty soon we were getting lessons on global warming. What happened?

    A meme is what happened. When the first person posted on a political matter, it reflected his private belief that this was acceptable behavior on a list devoted to ontology. By the time a few others had posted on politics, a shift in attitude had occurred, and this behavior was deemed acceptable. One person's belief had spread across the list, thereby becoming a meme. Along the way, the culture of the list had evolved.

    Why was this meme successful? Because it was selected by its environment, which in this case happens to be the minds of the participants. This notion, that it's okay to post on politics, appealed to listmembers at that moment. Note that the people who took up the discussion may not have consciously thought to themselves, "It's okay to post on politics." They were just thinking, "Someone's got to respond to this rubbish." But in the process, the meme dug itself in.

    To repeat, environmental selection can act as a mechanism of cultural evolution. The environment in this case is the mind. We can indeed observe the mind. As self-conscious entities, we do so routinely.

    This is dualism. The mind is not an abstraction that must take material form to exist. The information and the brain matter do not exist independently. There is only one thing, and we can view it internally, through reflective thought, or externally, by examining our brains. Only when we look at it interally do we find memes or ideas. Otherwise it's just chemicals. While it's true that the electro-chemical pattern established in a brain should (theoretically) correspond to a particular idea that a particular individual is currently considering, this is not the case with memes, as memes exist in many different minds, and the neural pattern established in one brain can be totally different from the pattern established in another brain for the same meme.

    Are you saying that to recall a phone number, you have to somehow "read" the synaptic patterns in your brain? This would entail knowing the language your brain uses, so you would have to know not only English but brainese. Fortunately, the mind doesn't have to read the brain. What the brain does is simply the external perspective onto what the mind is doing.

    No, I'm a human person.

    Not at all. The virus exists in the computer circuitry. However, nothing in a computer-- viral or otherwise-- has any meaning except in the mind of the person who interprets its activities. Unlike a brain/mind, the matter comprising a computer is not simply one perspective onto a greater whole. It *is* the computer.
