This is the second edition of this successful critical thinking text. It includes all of the core topics covered in the course, such as critical reasoning, argumentation, logic, and argumentative essay writing, but also introduces topics such as inference to best explanation and scientific reasoning. The new edition also includes material on evaluating evidence and credibility, evaluating the media/advertising, and intelligent design. The art program has been expanded from 25 to 60 photographs, and the book will now be in full colour.
