Finally got started on this book. I get the necker cube now. Dawkins does have a marvelous way of explaining complicated ideas. Here he uses the analogy of the Necker Cube to flip between the two visions of evolution: the selfish organism and the selfish gene. There's an almost cinematic quality to this passage:
"We look at life and begin by seeing a collection of interacting individual organisms. We know that they contain smaller units, and we know that they are, in turn, parts of larger composite units, but we fix our gaze on the whole organisms. The suddenly the image flips. The individual bodies are still there; they have not moved. But they seem to have gone transparent. We see them to the replicating fragments of DNA within, and we see the wider world as an arena in which these genetic fragments play out their tournaments of manipulative skill." (pg. 4-5)
I'm reminded of that William Blake poem Robert posted when we started discussing The Selfish Gene.
It really is amazing to see both the micro and macro views and to be able to flip between them.
