I have read this book several times now and continue to refer to it whenever I need to clarify arguments regarding important issues. It is unfortunate that neither Indigo nor Amazon list the complete title of the book: 'How to Become a Really Good Pain in the Ass: A Practical Guide to Critical Thinking'. I would like to see both dealers correct this since Dr. diCarlo's book is much more commonly known by this title. There are literally thousands of Critical Thinking books available but this is, by far, the best.
