Meaning can be enhanced by breaking the order; the exception points up the rule. A building with no "imperfect" part can have no perfect part, because contrast supports meaning. An artful discord gives vitality to architecture. You can allow for contingencies all over, but they cannot prevail all over. If order without expediency breeds formalism, expediency without order, of course, means chaos. Order must exist before it can be broken. No artist can belittle the role of order as a way of seeing a whole
relevant to its own characteristics and context. "There is no work of art without a system" is Le Corbusier's dictum.
