In this handbook Ran Lahav explains the general principles of the philosophical companionship and provides a detailed list of practical procedures and exercises. A philosophical companionship is a group of people who meet online or face-to-face and contemplate in togetherness on philosophical ideas. They resonate with each other and give voice to their inner depth, developing together profound insights. The companionship format has been developed in recent years by Ran Lahav and his colleagues from the philosophical practice movement.
