Functionalism was entirely consistent with the rationalistic and mechanistic world-view which rose to become the dominant European ideology in the seventeenth century. Believing, as they did, that the cosmos was a complicated clockwork, Descartes, Newton, Bacon, and their ilk maintained that it could be analyzed, reduced, investigated and ultimately controlled. If the universe is a machine, it is easy to assert, as did Le Corbusier, that a house ought to be one. It was this connection with science which ultimately distanced the functional approach from ordinary people and delivered it into the hands of technocrats. This did not begin to happen until the emergence of the social sciences in the nineteenth century when functionalism became linked with ideals of social progress and revolutionary political developments.
