This book was a bit difficult for me, since I have only high school science training. But it's an interesting topic so I stuck with it. And actually, I think the author did a pretty good job of making it intelligible for the layperson. I believe I understand his general theories. That biology is really just complex chemistry, which is just complex physics ... okay, I can buy that. That the biology of how life started can be better understood if we examine it in terms of chemical processes ... okay. A lot of what he does is redefinition in simpler terms, and it was helpful to me. I don't know how his theories hold up when reviewed by other scientists, but it doesn't matter that much to me. I feel like I understand the issues much better now.
