A dialogue has no predefined purpose, no , other than that of inquiring into the movement of thought, and exploring the process of "thinking together" collectively. This activity can allow group participants to examine their preconceptions and prejudices, as well as to explore the more general movement of thought. Bohm's intention regarding the suggested minimum number of participants was to replicate a social/cultural dynamic (rather than a family dynamic). This form of dialogue seeks to enable an awareness of why communicating in the verbal sphere is so much more difficult and conflict-ridden than in all other areas of human activity and endeavor.
