utopian engineering
Term used by Karl Popper in [Popper45a] for approaches to social engineering which involve first drawing a blueprint (i.e. describing the desired utopia) and then devising an implementation plan. Utopian engineering is contrasted with historicism, which is fatalistic and therefore may regard blueprints and plans as superfluous, and piecemeal engineering, which, fearful of repeating past blunders of utopian engineering, confines itself to a kind of sociological firefighting.
