THE SUPREME ART OF DIALOGUE - STRUCTURES OF MEANING This is a prime source for the theory and practice of the dialogue process as advocated by David Bohm and his mentor Patrick de Mare. It looks at dialogue in relation to the physics of wholeness, phenomenology, meditation, the fourth way of Gurdjieff and John Bennett, social change and religion. The author introduces the new concept of N-logue to designate levels of dialogue and spells out the deep relation between conscious and explicit disciplines and free-floating conversation. He argues that dialogue offers a way of developing new organs of perception and is an intimation of a synergic epoch of mind.
