If I were a Christian, I would be deeply embarrassed by Morris's habitual errors of fact and logic, and above all, by his seething hostility toward scientists and any field of study that challenges his own beliefs.
From beginning to end, this book is a ranting, almost maniacal, tirade against the theory of evolution, which Morris attacks so strenuously that he apparently neglects to cast a critical eye toward his argument. Morris's assertion that evolution is the root of all evil (almost literally) is simplistic and riddled with logical errors. For example, Morris states adnauseam that evolution was central to Nazi doctrine, which he offers as proof that it is "Satan's lie," and the cause of everything from pornography to the dissolution of the nuclear family. Curiously, Morris is not equally troubled by hideous misapplication of Christian doctrine throughout history. Similarly, Morris attacks evolution by pointing to mystical beliefs that predate it, yet he exempts Christianity from the same scrutiny.
Remarkably, Morris fails to demonstrate even the most rudimentary understanding of evolution, offering only naive interpretations and superficial historical facts about Darwin (Morris's devil incarnate). Morris's "science" is so sophomoric he appears to fabricate it on the fly, never pausing to analyze it, or even to check fundamental definitions. For instance, Morris asserts that evolution "...goes squarely against the second law of thermodynamics." However, the 2'nd law applies only to "closed" systems, and therefore to none of Morris's scenarios. Morris also asserts that the "...study of biology shows no evidence whatever of evolution occurring in the present,..." which is such a muddle it's difficult to interpret. Is he unaware of 20'th century biology? Would he expect to see speciation happening before his eyes? Perhaps a more earnest writer could use such a statement to launch a deeper discussion, but for Morris it is the argument in toto.
To counterbalance Morris's view, I urge both theists and atheists to read Robert Wright's book, "The Moral Animal." The contrast between Morris and Wright is so extreme at several levels that you will find it entertaining if not deeply informative
