<p>A fun introduction to using a brain. A Thinker&rsquo;s Book of Dangerous Knowledge takes a straightforward yet humorous approach to that most dangerous activity known to humankind: thinking. This book is humorous, thought-provoking, and paradigm-shifting. This book will pique the interest of the average thinker, and make them laugh or at least groan appreciatively as they navigate their way through what has typically been a dull, dry subject. It has pictures, diagrams, cartoons, and takes a whimsical approach to completely altering one&rsquo;s perception of perceiving. Though brains are soft and squishy, books on critical thinking tend to be hard, migraine-inducing, and about as much fun as stapling a piece of liverwurst to an angry tiger. Not this book. It is a fun introduction to using one&rsquo;s brain for critical thinking. Unfortunately, thinking for oneself is neither popular nor even particularly safe. To be blunt, this book is extremely dangerous. Readers may laugh, groan, roll their eyes, rage at the printed word, squint incredulously, and/or may even begin thinking for themselves. Readers may also fart a lot, depending on what they had for lunch. Readers are strongly advised to put the book down and back away slowly to a safe distance.</p>
