This book will help you to reason critically; to recognise, analyse and evaluate arguments and to classify them as inductive or deductive. It will introduce you to fallacies (bad arguments that look like good arguments) and, in two optional chapters, to the rudiments of formalisation. Linked to Marianne Talbot’s hugely successful Critical Reasoning podcasts (downloaded 4 million times from iTunesU!), and full of exercises and quizzes, the book was written to satisfy demand from fans of the podcasts. Marianne is the Director of Studies in Philosophy at Oxford University’s Department for Continuing Education. This is version 1.1 of 'Critical Reasoning' which resolves the formatting issues in the first version.
