Contrast between the inside and the outside can be a major manifestation of contradiction in architecture. However, one of the powerful twentieth century orthodoxies has been the necessity for continuity between them: the inside should be expressed on the outside. But this is not really new--only our means have been new. The Renaissance church interior, for instance (137), has a continuity with
its exterior; the interior vocabulary of pilasters, cornices, and drip mouldings is almost identical in scale and sometimes in material with its exterior vocabulary. The result is subtle modification but little contrast and no surprise.
