Don't waste your money on this book. Every article is so liberally biased that even my extremely left-wing teacher had a problem with it. The articles are not varied and every page contains a political agenda, which in my opinion defeats the entire purpose of education. The compilers of the various essays did a great job of covering up their agenda, and at the first glance of the Table of Contents, one would think that this was a decent resource, but that is not the case. Unfortunately, even the articles that should be unbiased, with authors like Plato and Albert Einstein, are followed by "discussion questions" that obviously intend to steer the reader in one direction only. I was forced to buy it for a class, and once I discovered what it was, would rather have failed than know that my money supported the publishers of this propaganda.
