Contrary to the general belief that modernist art and architecture reflect the technological society, Jacques Ellul maintains in his "L'empire du non-sens" that they are justifications for the integration of humankind into what he called the technicist complex. Modernism in art and architecture meant that every product must be qualified by a technological character. This unassailable belief exerted some far-reaching influences on symbolic thought, on artistic expression, on architectural character. If imitation and invention were the two inseparable concepts through which art and architecture were produced and symbolized, it is because they operate on a certain transparency between an exemplar and a work of art. By contrast, in the mentality of technique, artistic production operates based on a certain opacity to meanings outside of itself. Imitation and invention were separated. Thus, one of the principal beliefs in modernism, that art and architecture symbolize the technological society is actually one of its weakest. In considering technology as both the symbol and the product, the artistic idea and its representation collapsed into each other. (Contains 14 notes.)
