An invitation to the habits of good thinking from philosopher Julian Baggini. By now, it should be clear: in the face of disinformation and disaster, we cannot hot take, life hack, or meme our way to a better future. But how should we respond instead? In How to Think like a Philosopher, Julian Baggini turns to the study of reason itself for practical solutions to this question, inspired by our most eminent philosophers, past and present. Baggini offers twelve key principles for a more humane, balanced, and rational approach to thinking: pay attention; question everything (including your questions); watch your steps; follow the facts; watch your language; be eclectic; be a psychologist; know what matters; lose your ego; think for yourself, not by yourself; only connect; and don’t give up. Each chapter is chockful of real-world examples showing these principles at work—from the discovery of penicillin to the fight for trans rights—and how they lead to more thoughtful conclusions. More than a book of tips and tricks (or ways to be insufferably clever at parties), How to Think like a Philosopher is an invitation to develop the habits of good reasoning that our world desperately needs.
