Apropos AN Whitehead, I listened to an interesting talk the other week [1] about "process philosophy", specifically in phil of biology. The speaker (John Dupré) thought that he was working along the same lines as Whitehead, but that he was a poor writer so no-one can really be sure if they understood him.
