Query: Ehrlich trips over himself.

Joel Kauffman's review is as close an honest reality check you can get for the contents of this book.I was skeptical about many of Ehrlich's own skepticism. When he appraoched and debated John Lott, I knew that Ehrlich's prose was more about convincong himself that his own sacred cows are beyond reproach. Lott dismantled most of Ehrlich's criticism to the degree that left Ehrlich stnading there in his tidy whities.This is not to say that a good share of what Ehrlich writes about here has underpinnings but even John Stossel knows better than to make some of the mistakes Ehrlich makes.
