How to Think More and Better

William B. Irvine, author of the popular book "A Guide to the Good Life," offers much needed philosophical advice on how to become a more rational and critical thinker in today's emotionally-driven and complex world.Even the most reasonable of us can be selective about when we think reasonably. We may realize that the best thing to do is to take the advice of our doctor when facing a medical issue. When shopping for a new car or appliance we might carefully assess online reviews and weigh our options calmly before making an informed decision. But when it comes to things that feel more fraught --voting, navigating a challenge in our family, figuring out what to do in a difficult professional situation-- we might throw this approach out the window, dismissing facts and patterns that form a body of evidence, and trust our gut. (Of course, there is a time and place for this, but not every big decision is purely a matter of the heart.) Likewise, when we think about big ideas, about right and wrong, or about concepts so complex they make anyone's head spin, we can freeze, jumping to conclusions rather than wading into the details, or considering the existing arguments that others offer as a trail through challenging terrain. How can we do better? How can we train our minds to be more consistent? How can we practice using the best of our rational abilities when it matters most?How to Think More and Better offers a philosopher's advice on becoming a more rational and critical thinker, rather than relying on emotions or hearsay to reach important decisions. It trains the reader in open-minded critical thinking. This thinking is crucial in a time of political polarization, social media, politicized news media, and echo chambers, to help us pursue truth and understanding in a world of rabbit holes, echo chambers, and disinformation. Irvine explains the prevalence of emotion-driven thinking is often at the expense of engagement with evidence, and then lays out strategies readers can use to train themselves to think more critically, drawn from what worked for him in the classroom. He also covers important areas to aid intellectual self-transformation, such as Mindcare and Mindcleaning. With practice, most people can become evidence-based thinkers. Seemingly intractable contemporary problems might be solved if we all start engaging more in this kind of slow and careful thinking, considering arguments and evidence even from those on opposite sides of key debates.
