Donald Schön's paper concerns the cognitive function of generative metaphors, as they were dubbed by the author, in problematic situations. They can in fact be viewed as problem-solving situations, but also (and more usefully, in Schön's opinion) as problem-setting scenes. From the problem-setting perspective, the process of the naming and framing of social reality proceeds via generative (deep) metaphors, even when we are not aware of this fact: "my point here is not that we ought to think metaphorically about social policy problems, but that we do already think about them in terms of certain pervasive, tacit generative metaphors" [p.139]. For instance, Schön mentions two stories in which "the urban-housing situation is seen first as a disease which must be cured and then as threatened disruption of a natural community which must be protected or restored" [p.147].
