Conversation Theory was conceived and developed by Gordon Pask in the
days when he was Research Director of System Research Ltd, a non-profi
t research organisation, founded in the 1950's. I worked with Gordon a
t System Research Ltd. between 1968 and 1978. Here, I give a personali
sed account of the development of Conversation Theory and its applicat
ions as I observed and participated in them during those years. Conver
sation Theory is reflexive: it explains the observer to himself. Being
party to its development was a journey of self-discovery and self-inv
ention in which Gordon was my guide and mentor. I have ordered my acco
unt chronologically; I have also tried to show how Conversation Theory
evolved in a ''boot-strapping'' manner as a tool and as an explanatio
n of its own significance. Gordon, par excellence, knows how to foster
creative conversation and ''moments of excellence ''.
