Stephen Pinker does an admirable job debunking the myth of the blank slate in this tome. Yes, what he says should be common sense by now. No, it is not.
There are many places in the book where Pinker's values and background become evident. However, these are a small price to pay for a great book.
So, what does Pinker do that's so great?
1) He takes his opponents seriously and mounts his case slowly, step by step, taking the reader along with him.
2) He illustrates that having a blank slate view of human nature is not morally righteous at all. (important for all those disposed to the moralistic fallacy)
3) He does not talk down to the reader. Contrary to another reviewer, this book is not overly simplistic. There are points here and there where debate is possible, but overall it is highly accurate.
When you are done with this book, you should have no doubt that genetics and evolution were and are very important in human life. Natural selection is the only theory which can explain human behavior- period.
On the more controversial side, Pinker devotes many pages explicating Judith Rich Harris' theory about child development. Her views are very contentious, but provocative. Her basic argument is that children are MORE influenced by peer group socialization than the parenting style they lived under. Harris reached this conclusion after studying the behavioral genetic evidence. In behavioral genetics, it is known that all measured traits are heritable. Further, after subtracting genetic influence, unshared environment accounts for most of the left over variation- not shared environment. This is perplexing to most because it suggests that most environmental influences on personality come from WITHIN families not BETWEEN them. In short, two adopted siblings are no more alike than two strangers on the street, even though they share the same environment. Wheras, two twins seperated at birth are no more different than two twins who grow up in the same household.
Pinker largely accepts Harris' theory, with slight reservations. D.C. Rowe presented a similar theory years earlier as well. The controversy still rages. It is a bit premature to pick sides. Pinker seems to, but he does tell the reader that Harris' theory is the minority view.
In the end, this book can be read with pleasure by anyone. It is especially usefull to cite as a reference when having vapid debates with soiciologists. Most of Pinker's statements should be truisms. Unfortunately, they are not; Fortunately, he took the time to synthesize the insurmountable evidence against blank-slaters!
