To start off I think this book is a 3.5/5. I gave it a 3 simply because I could not round up and give it a 4. I'm unlikely to buy any more of David Berlinski's books. I say this as someone who does find problems with Darwinian evolution and is interested in reading more about the origin of the Big Bang and cosmology, the origin of life and holes in the evolutionary theory. Mr. Berlinski appears to be fair and critical throughout much of the book and it's a large book full of information. However, I have a problem with how it's written.
The book is written at a very high level - both in content and vocabulary. I graduated with an Honours degree in Math although my English has never been great. I'm not an idiot but I felt like one as I was always heading to an e-dictionary for some of these words he uses when a simpler and more common word is available. Even some of the words for latin species could have used a footnote on what they are referring to when a common person is reading. I know some of the works were published in scientific journals and aren't intended for an average audience but when you package it to sell to the world some further explanation is necessary imo.
Some of the chapters are overly long which include the published works and rebuttals. Interesting but a bit too long. I would have preferred the rebuttals be placed immediately after each letter but to each his own. The chapter on Gödel's Question is probably the worst one in the book. Just so technical as it's basically a high level mathematical paper far above the average person's head. Berlinski pays tribute to Stephen Jay Gould in part of the book and yet never references his unique views on evolution (static periods and then turbulent ones). He spends a lot of time covering only parts of some things like the Big Bang. He's infatuated on whether the universe is expanding and yet there are so many other interesting things in cosmology to discuss (what exactly happens in those first seconds and minutes, evolution of solar systems, etc). The essays are older so we don't even hear about dark matter or energy. Mr. Berlinski discusses the origin of life but doesn't go into enough detail with Miller's experiment or other theories that attempt to explain it. He does go over a lot of other things but it's clear he doesn't discuss everything involved in a subject - just the things he personally finds most interesting.
The stuff on Einstein and the evolution of science with stories on some of the scientists were some of my favourite parts and were good. The battles over Darwin's evolution are good but I had read quite a bit of some of this stuff in other sources - sources that were much easier to read and explained things better. I also enjoyed the discussion on the human language.
In the end the book had some interesting things but it was long (547 pages) and a fairly difficult read. I imagine those that are hard core evolutionists would not like this book although Mr. Berlinski gives his opponents plenty of space to criticize his papers (two large sections where this happens). For those that are inclined to believe God has a hand to make some of the improbabilities of our universe come true which include answering the questions about the origin of the universe (what caused the Big Bang) and the origin of life, this book may be for you. But just be warned that it's not an easy read, the book obsesses a long time over certain things while not fully exploring others in the same genre. I would suggest there are other books out there that would probably provide the same information you are looking for. I don't have any recommendations on new books. The one book I had read in the past (may be dated now) that was excellent was "Creation: Facts of Life" by Gary Parker. Mr. Parker is a young earth creationist (not what I personally believe) but his discussions on the origin of life, DNA, embryonic development, mutations and fossils actually covers a lot of what Mr. Berlinski goes over in these areas but in a much more interesting and easier to read style. Mr. Berlinski comes across as the brilliant teacher that is unable to connect to his students and it shows with how he chooses to write and get his point across. I wish I enjoyed the book more but I do feel disappointed considering how many good reviews this book received when I previewed it.
