This paper builds an argument for the use of a set of process level assumptions to guide selective integration of structural and strategic approaches to therapy. While the use of these two views conceptually to construct a case may add -richness and perspective similar to binocular vision; therapist attempts to act simultaneously on these two views is compared to operating on the world as seen through a pair of glasses with mismatched lenses. In this case, contradiction, confusion, stumbling or paralysis may result. The two views are compared to alternate levels of system description, and the problems of using biologically based assumptions in a process dominated social system domain are reviewed. The increased facility of adopting process level assumptions to selectively integrate the metaphors and tactics of alternate views is strongly recommended.
