Popularised by the Dunbar Number, which suggests that our cognitive limit for maintaining stable social relationships is around 150 people, this book is a fascinating if highly cerebral and scientific take on friendship, trust, loneliness and social cohesion. Its academic exploration provides a practical guide  and homage to human connection for anyone looking to understand the nuances of friendship groups.

The central theme of this book is the concept of living an undivided life, where one's inner truth aligns with their outer actions. The writing is both poetic and accessible, weaving together personal anecdotes, philosophical reflections, and practical advice that is engaging and thought-provoking. Highly recommend if you are looking to bridge the gap between your inner and outer worlds and to live with greater purpose and integrity.

Essential, practical & vital

Beautiful, poignant & touching
