These points are valid, but I have two observations. The first is that self-reinforcing sets are surely a natural part of a properly functioning consciousness. They come up all the time in science, for example.

The second comment is that I think Dawkins is thinking too hard. There is a much more obvious, and truthful, reason why people have faith. It is not because they think it is virtuous, and it is also the main reason they reject evolution. People do not want to believe that they live in a world that emerged at random, and has no real point, no higher mission. They feel in their bones, for whatever reason, that life matters more than that. They derive a greater sense of importance by believing in a higher power. This is the piece that science must address if it wishes evolution to supplant creation as the dominant mode of thought about our origins. Personally, I feel that each mode has its place.
