Partial and full information.  Representation in architecture encompasses multiple modes, including built objects, physical models, virtual models, data arrays, plans, sketches, photographs, and drawings. Each such mode may be viable as representing an architectural object just in case some features of the object are adequately, accurately, regularly, and optimally represented through the mode. This view of viable representation in architecture is at odds with the standards for such in other artforms. Consider a representation of the Mona Lisa. If you do not have complete visual access through the representation (from any acceptable angle) to the full tableau, you may be said to lack full acquaintance with the work through the representation, and your consequent aesthetic beliefs about the Mona Lisa may be discounted accordingly. By contrast, if architectural beliefs required anything like full acquaintance with the object or fully informed testimony to be viable, our architectural beliefs would not typically or frequently be viable.  Rare is the case where acquaintance is full or testimony fully informed—even among those whom we might expect to have the greatest acquaintance, such as a built structure’s architect or developer.
