The reason I thought it would be interesting to hear people's comments about this short commentary was that I found it rather poor.
There are really three things I disliked. The first was its tone, which I found rather rude. Sloan Wilson expected an evolutionary and it does seem to me natural to read Dawkins expecting an evolutionary commentary - evolution, after all, has been his field thus far. Of course, he is not obliged to continue in the evolutionary vein. However, those comments about Assyrian woodwind instruments look like deliberate mockery and seem to suggest that he (Dawkins) regards Sloan Wilson's views as beneath serious consideration.
That brings us to the second point I disliked. Dawkins chooses to insinuate that Sloan Wilson is some solitary loner obsessing about group selection for thirty years. The reality is very different. Many people take Wilson's views seriously and group selection is, today, a topic of active debate. One must presume either that Dawkins is unaware of this, or that he simply chooses not to debate Sloan Wilson, perhaps for the same reasons that he chooses not to debate creationism. Should I, or others, infer that he (Dawkins) places group selection into the same category as creationism?
Finally, the last point I am unhappy about, I am quite disappointed that Dawkins did not take an evolutionary view of religion. That leaves me wondering what "The God Delusion" does achieve. From objective criteria it is not hard to debunk religion, even comedians do it, for example, "The Life of Brian." Its no great achievement to debunk religion that way, so what is the point of the book? Is this work a social commentary, if so, how does it improve on Durkheim's "God is society" approach - which makes sense in terms of group selection. If it is an ethical approach to knowledge, how does he (Dawkins) add to Ghandi's "God is Truth." If the "God Delusion" is not about evolution, what area of knowledge does it actually move forward?
