The philosophical companionship is a group-activity that combines contemplation and philosophy. Companions are a group of people, philosophers or non-philosophers, who meet online or face-to-face to contemplate in togetherness on philosophical ideas. Resonating with each other and giving voice to their inner depth, they develop together profound insights. The companionship format has been developed in recent years by Ran Lahav and his colleagues from the Philosophical Practice movement. This handbook is a practical and theoretical guide to companionships. Ran Lahav explains here the general principles of the companionship and provides a detailed list of practical procedures and exercises, for the use of facilitators and groups wishing to experience philosophical contemplation.
