This book contains 101 short refutations of common errors about politics and economics. Each is about 300 words, so it's a handy book to bring out in an argument - just say "read this page".
Each page is very clearly written, so very easy to understand. I was familiar with many of the arguments, but some were new to me, and others were expressed better than I had seen before.
I only have two criticisms. Firstly, some "errors" and their refutations are quite similar. Often 300 words isn't quite enough, so two separate pages are used, perhaps lessening the impact of the argument. But perhaps the repetition with slight variation is good, and in any case running over one page would subtract from the simplicity of the format.
Secondly, it would be good to have the page numbers start with the first article, so the last one was page 101. The introductory pages could be numbered with roman numbers. Perhaps this could be fixed in the next printing.
Overall, excellent. Buy copies for all your lefty friends. They'll benefit, and so we all will.
