Other subtitles for this book could have been, "Critical Thinking 101" or "A Skeptic's Guide to the Universe." This is one of the best books on critical thinking I've read, and I've read a lot. Right up there with Sagan's "The Demon-Haunted World". In this day of "alternative facts" and fake news, books like this or more important than ever. This book should be a part of all high school curriculum. Seriously.
