This book is not really about being right. It’s about winning arguments, even when you’re wrong. The 38 tactics include such classics as “Use your opponent’s views”, “Beg the question” and the ultimate: “Become personal, insulting, rude”. You’ll recognise these from many annoying and unsatisfying arguments you’ve had. This book helps you avoid them, and if necessary, use them yourself. Very useful, and all based on “the natural baseness of human nature”. Perhaps it’s best not to dwell on that.
