A project, precisely because it's a bearer of novelty, must solve contradictions and follow rules-its novelty is the "new" application of an existing rule, the extension of an existing rule to a "new" context, or the institution of a "new" rule.
Not just that: given that the rules in architecture are as numerous as they are different-we can think here of certain "laws" (static laws, hygienic/sanitary codes, morphologic influences, etc.) and cultural aspirations (ethical, philosophic,aesthetic, etc.)-the architect's puzzle becomes a sort of arbitration among the different viewpoints, each with various dimensions. Finally, a creative action must be triggered for the possible-to-actual transition to occur; an action that is not merely abstract but rather "competent and aware of the objective," as the theorist of problem solving Genrich Altshuller says.
