How may mental activity be conceptualized within the context of the ep
istemology engendered by cybernetics, and how may that epistemology ac
count for imagination? I argue for an epistemology of imagination that
both distinguishes imagination, understanding and interpretation, and
unites all three concepts in a dialogical circle of ideas. The proces
ses of distinguishing these concepts (and the processes that give rise
to and describe mental activities) are dialogical processes. As dialo
gical, they fall within the scope of Heinz von Foerster's work on seco
nd-order cybernetics.
