This foundational 1991 document emerged from conversations exploring David Bohm's suggestion that incoherence in human thought is the essential cause of humanity's crises. Bohm, Factor and Garrett define dialogue as distinct from discussion (which 'breaks things up'), debate, or therapy. The key concept is suspension: giving serious attention to reactions, impulses and feelings so their structures can be noticed while occurring. This slows down the movement from thought to feeling to action and reveals deeper meanings. The paper introduces koinonia, 'impersonal fellowship', describing a shared consciousness where creativity and insight become available. But it warns against basking in this 'high' rather than pressing into challenging territory. Thought, in Bohm's expanded definition, includes not just intellect but feelings, emotions, intentions, desires, and tacit non-verbal processes. The document concludes with practical guidance for starting dialogue groups while emphasising that no firm rules exist; the essence is learning through creative participation between peers.
