Michael Lissack positions in that space and they allow purposeful movement within that space. People must reach a great number of destinations during a typical day, and they are normally quite aware of their positions in the surrounding space and in the larger environmental context. Not only are people quite efficient at these movements. but they execute them often in an automatic or semiautomatic fashion. When everything works according to plan, the mental operations required will pass unnoticed. However, the state of being disoriented, of being confused about one's position in a surrounding space and the actions necessary to get out of it, is a deeply felt experience. Disorientation is a problem that has preoccupied mankind in the past and as the built environment has grown in size and complexity, it has in- tensified. Disorientation can provoke frustration and stress and may have disastrous consequences. Kevin Lynch takes a particularly strong stand in his Image of the City. He notes that to get completely lost is a rare occurrence but: "Let the mishap of disorientation occur and the sense of anxiety and even terror· that accompanies it reveals to us how closely it is linked to our sense of balance and well being. The very word lost in our language means much more than simple geographical uncertainty: it carries a tone of utter disaster." Architecture is a process of discovery and learning. In the course of seeing, moving, and seeing yet again, the architect discovers unanticipated patterns, relationships, and possibilities, which may inform further archi- tecture. As he plays out webs of moves and discovered consequences, for example, an architect may learn about the nature of the problem implicit in a particular configuration of the features of the site, program, and constraints. An entire episode of architecture may function, then, as a source of learning that enables the architect to readdress the project at hand or tackle a new project more intelligently. Projecting this relatively simple view of architecture onto the field of government policy making, we see a policy architect who constructs, in some relatively protected forum, a representation of a policy or program that will be sent out, upon its completion, into an actual policy environment. As the representation of the policy object takes shape, the policy architect's
