The author should have stopped the book after the first third. He would have had a brilliant book. He teaches the reader of the value of narratives and of the networks (or using William Van Orman Quine's word 'web' when he's identifying one of his 'values' of science) we use in understanding what we believe is reality.
I have the advantage of hindsight. He's writing around 2007 and a lot of things have happened that really color my attitude against the author's approach. For example, his compromised approach on Gay Marriage being re-branded as 'civil unions' is not what happened (thankfully). That would have been the wrong approach. As Hegel said regarding philosophy, "any shoe clerk thinks he understands philosophy", and just as readily I can say 'everybody thinks they are an expert at politics'.
The election of a president who makes absurd statements such as "Climate change is a Chinese Hoax", or "we should not only kill the terrorist but the terrorist's family", or "waterboarding is not torture and we should do even more" shows that even someone who makes psychotic sounding statements (each one of those three statements strike me as coming from a psychotic with either no empathy or a pathological understanding of reality) can sway Americans who want to be swayed.
It sucks being a Democrat and I'm holding out for Elizabeth Warren or Sherrod Brown in 2020 who don't need to read a book like this one because they already know how to speak from the heart and should be able to beat a person who speaks like a psychotic.
