Like all books by Himmelfarb, this one is erudite, well written, informative, insightful and sure to upset the politically correct which for me makes it five stars.
In first presenting the historical information about Darwin and his theory and then analyzing their historical and cultural effects, the author does a comprehensive job in presenting a balanced picture. However it is just this evenhandedness which will incite those secularists who hold Darwin up as the destroyer of God and the founder of the Scientific view of creation for Himmelfarb shows that Darwin himself never made these kind of claims, and that indeed the theory is just that- almost a pure thought hypothesis that has NEVER been experimentally verified, for in all the millions of fossils discovered to date there has never been an example of one species "evolving" into another, the cornerstone of what Darwin was trying to explain. While excuses abound for why this is so, nonetheless it is a fact which glaringly highlights that, while Darwin postulated A scenario for evolution, it may not be THE scenario.
Another interesting fact the author reveals is that many of the original defenders of the theory did so less from being convinced of its truth than for the "freedom" it offered from religious constraints on scientific inquiry, again highlighting the fact that it was more a philosophical revolution and less a scientific one that Darwin initiated.
As for the popular Liberal claim that God was no longer necessary because of natural selection, well, anytime science attempts to deal with metaphysical questions of "why" as opposed to how, it runs into problems which it cannot, almost by definition, answer. Specifically in this case, the claim that mutations are random is impossible to verify scientifically. How can we prove there was no underlying reason for the way change occurred, even if natural selection vetted these alterations and picked winners and losers? Even Richard Dawkins, the acclaimed scientist and radical atheist, believes evolution is geared to complexity. If it were truly random, why would this be so?
In dealing with these and other aspects of the debate the author is enlightening and informative, assuming you are not so closed minded that any detour from the Liberally approved path is forbidden. Himmelfarb is a brilliant historian and thinker who presents the facts and allows the reader to draw his own conclusions. It is the kind of refreshing attitude that Darwin's supporters once prized, before Darwin himself became ossified as dogma for many of his current day followers who mistakenly consider themselves openminded.
