In Think, Why You Should Question Everything, Guy puts forth a compelling case for skepticism over credulity, scientific thinking over superstition.
In Chapter 1, Standing Tall on a Fantasy-Prone Planet, Harrison sets the groundwork for the book, on the value of scientific thinking, what skepticism is, why it matters, the need for taking responsibility for one’s own mind, and the wonders to be found in the real world even while still enjoying fantasy and fiction, and just as crucially, the use of a healthy approach to belief and believers, with a non-adversarial attitude toward the latter. He notes in this chapter that even the smartest of us can be prone to conviction in the most questionable claims, and the importance of vigilance in skeptical thinking.
Chapter 2, Pay A Visit to the Strange Thing That Lives Inside Your Head, discusses the biases and flaws in the everyday workings of even the most normal and healthy brains, in such things as the notorious fallibility of human memory, biases in our thinking, and perceptual quirks that can so easilly mislead even the best, sanest, and most intelligent of us, with a cautionary story of weak skepticism, The Tale of Little Gretchen Greengums, showing how even seemingly harmless credulity can vastly impact our lives in less than favorable ways.
Chapter 3, A Thinker’s Guide to Unusual Claims and Weird Beliefs, surveys a variety of extraordinary claims, such things as conspiracy theories, astrology, psychics, the Roswell UFO crash, miracles, Area 51, the Bermuda Triangle and other assorted oddities.
Chapter 4, The Proper Care and Feeding of a Thinking Machine, deals with ordinary means of maintaining good brain health, including healthy sleep habits, eating well, the most consistently reliable favor for your brain, regular exercise, and my favorite: reading as much as one can during the waking hours. The upshot? It’s your brain, and yours only — use it or lose it!
Chapter 5, So Little to Lose and a Universe to Gain, discusses the upside of all this fuss over one’s thinking; the wonders of reality to be gained, the benefits of clear, reliable thinking, and the things possible with thinking rooted in a firm grasp of what can really be known. Skepticism doesn’t have to be scary, and can indeed be empowering and liberating to those who embrace it.
Think is in my view one of the best guides to clear, reliable thinking that I’ve read in a while, and I’ve seen a few. Like some of Harrison’s earlier books, 50 Reasons People Give for Believing in a God, 50 Popular Beliefs That People Think are True, and 50 Simple Questions for Every Christian, this is a very user-friendly book, in the dual sense of being easy to read without its being dumbed down and its non-antagonistic approach to readers who may not be familiar with scientific skepticism both as a method for thinking and system of intellectual values.
I’d recommend this book for both good skeptics seeking to be better skeptics, and for current believers in the paranormal or supernatural curious about and interested in sharpening their ability to inquire into unusual and important claims without being bamboozled and parted from their money, political enfranchisement, or their health by con artists.
Skeptical thinking here is shown not as a destination, not a certain conclusion, but as a journey toward something ever closer to how things really can be known, as close as we can rightly say we do know without absolute or timeless Truths™. It’s a journey lasting a lifetime for each of us in a limited human timeframe, and throughout the whole of human inquiry over the centuries.
It’s something, both as a way of thinking, and as method of seeking answers, I find more useful and more satisfying than a need for false certainty, a need that too easily leads to mistaken conclusions, a sometimes dangerous need fostered by the media, popular culture, and charlatans or ideologues of all persuasions.
Think shows how to do so more reliably using methods tested by collective human experience over history.
Why a stronger, more consistent skepticism rather than the weak sort?
Weak skepticism can do more than just part the hapless victim from their money or their vote, it can also prolong grief over the loss of a loved one, and in the case of medical quackery, even kill. Weak skepticism is heavily promoted by despots, ideologues of all stripes, clergy, and people promising the latest magic snake-oil panacea for whatever ails you.
Even having identified as a skeptic these past seven years, I’ve found things here that I hadn’t considered, things new to me, and I recommend this book as something to come back to time and again.
