Rationality: What It Is, Why It Seems Scarce, Why It Matters

A user's guide to rationality acts as a follow-up to the bestselling Enlightenment Now Humans today are often portrayed as cavemen out of time, poised to react to a lion in the grass with a suite of biases, blind spots, and illusions. But cognitive scientist and rational optimist Steven Pinker argues that this cannot be the whole picture. A list of the ways in which we are stupid cannot explain how we're so smart- how we discovered the laws of nature, transformed the planet, and lengthened and enriched our lives. Indeed, if humans were fundamentally irrational, how did they discover the benchmarks for rationality against which humans fall short? The topic could not be more timely. In the 21st century, humanity is reaching new heights of scientific understanding - and at the same time appears to be losing its mind. How can a species that sequenced the genome and detected the Big Bang produce so much fake news, conspiracy theories, and 'post-truth' rhetoric? Rationality explains the key tools for rational thinking, guiding the reader through the basics of logic, critical thinking, probability, correlation and causation, and helping us to make rational choices alone and with others. Rationality matters. As the world reels from foolish choices made in the past and dreads a future that may be shaped by senseless choices in the present, rationality may be the most important asset that citizens and influencers command. Steven Pinker, the great defender of human progress, having documented how the world is not falling apart, now shows how we can enhance rationality in our lives and in the public sphere. Rationality is the perfect toolkit to seize our own fates.

Review :
Steven Pinker is the high priest of rationalism ... [This book] is an impassioned and zippy introduction to the tools of rational thought ... Pinker wants probability theory and psychological biases to be taught in schools and universities. Punchy, funny and invigorating, this could be the textbook. Steven Pinker is among the best science writers in history, and with Rationality he applies his talents to one of the most important and misunderstood human abilities - tracking reality with a brain that was designed to do so under some circumstances but not others. If you've ever considered taking drugs to make yourself smarter, read Rationality instead. It's cheaper, more entertaining, and more effective. The Enlightenment torchbearer is eloquent in his defence of clear thinking ... [reason] is a tool that human beings have to learn to use with care, something this book will help any reader to do. Rationality ­- like all of Pinker's work - [is] a paen to human potential... what Pinker really trades in are profoundly refreshing, energising sets of explanations for why we do and think the way we do ... harnessing reason is not just useful in all kinds of ways both personal and universal, but a wondrous property of being human. Almost every sentence in Rationality is crisp and intelligible, which is quite a feat, given that explaining logic to humans is like teaching them Sanskrit. Pinker suggests various ways to run our collective affairs more rationally. A reader-friendly primer in better thinking through the cultivation of that rarest of rarities: a sound argument. Rationality is a terrific book, much-needed for our time. In addition to drawing together the tools for overcoming obstacles to rational thinking, Pinker breaks new ground with the evidence he provides linking rationality and moral progress.
