This book, the fourth in Ryan Holiday’s ‘The Stoic Virtues Series’, shows that wisdom isn’t something we’re born with but a skill that requires ongoing effort and reflection. It makes the case that wisdom is the root of all other virtues and increasingly rare in today’s fast-paced world. Using examples from historical and modern figures, the author highlights the importance of thoughtful judgment, self-control, and questioning assumptions. The book warns against quick fixes and encourages patience and deeper thinking. Blending detailed stories with practical advice, it challenges readers to embrace complexity and develop mental resilience. While dense at times, the central idea is clear: true wisdom demands time, effort, and dedication. It’s a valuable guide for anyone looking to improve their understanding and make wiser choices in a distracted world. Many thanks to Profile Books Ltd and NetGalley for providing this advanced copy
