Abstract
Planningof any kind can be motivated by a pressing practical problem which has to be solved—for example, an increasing number of people may have to be housed in the same area; or by a long-term idealistic vision; or by both (the idealist seeing the long-term implications of an immediate problem). In short-term planning, the danger exists that the more technical problems may be solved, without attention to their implications for human beings; to take my housing example, higher and higher flats may be built, without considering the possible effects (e.g. the effect on social groupings). In long-term planning, Utopian or ideological blueprints may be produced.
