Have you watched the news recently? I read this book and started spotting logical fallacies everywhere. Even last week opponents to gay marriage were saying "If we allow this then what next? Three people getting married?" My first reaction was "well that's not a logical argument, it is the slippery slope fallacy". I have started seeing these fallacies everywhere in adverts, political statements and some of the most audacious claims attached to things.
The book was originally reccomended to me in a Podcast by the Merseyside Skeptics and I find it invaluable in looking at spurious claims I now see. If you have a questioning mind or want to win debates, then read this book, it is brilliant.
