When reading Harvey's latest book I found all the time spent on Leibniz and Whitehead very strange and disappointing. A bit if a red herring. What is the point of invoking these very obscure thinkers? L&W constructed two of the strangest metaphysical systems around. L&W were known primarily as mathematicians and not as philosophers. Whatever Harvey's motives, I'm sure he could have found a basis for his ideas in more sound and less woolly philososphies. Sam Pawlett
