This is a book that exposes fallacies in arguments - using actual statements by prominent persons as examples. The book is made up of 100 chapters with 99 examples each making a short chapter; the 100th chapter is not an example but a summary and last word. Bagginni's first chapter examines the statement by a NASA astronaut, Eugene Cernan who was reported as having stated: "No one in their right mind can look in the stars and the eternal blackness everywhere and deny the spirituality of the experience, and the existence of a Supernatural Being." Calling it an "argument from incredulity" Baggini explains why this statement "manages to pack three dubious, but persuasive, punches." This is a book that will help develop clear thinking, but as the author warned, some of his arguments might deserve the same flaws he sees in those he analysed. In mitigation, he explains that a player might commit infringements that he might have called "foul" had the player been the referee instead. This is a fine, readable book partly because it carries mostly contemporary examples although there are some historical ones such as one made by Samuel Johnson (chapter 22). The examples spread over many subjects, from politics to religion, to science, philosophy and literary criticism.
