I've given this five stars nostalgically, as I read this book in my teens and it had a highly formative beneficial impact on my thinking. As one of eight opinionated kids, I'd had and heard countless unproductive arguments. Reading Ruby's book explained why those arguments were all heat and no light. He made me realise how easy it is to argue at cross purposes, or to be misled by plausible irrelevances, and so on. It was mind blowing. The logical faults he explains can be heard every single day from the mouths of politicians and business leaders. This kind of book should be compulsory reading.
I'd think you'd struggle to find such a 'page-turner' logic book. It's a strange way to some up a logic text, but I loved Ruby's funny turn of phrase and excellent examples from both fiction and the real world. The book displays that Ruby is an excellent communicator of concepts. He made sense to me!
