The essential purpose of the interiors of buildings is to enclose rather than direct space, and to separate the inside from the outside - Robert Venturi

Perhaps it is the fate of all theorists to view the ripples from their works with mixed feelings. I have sometimes felt more comfortable with my critics than with those who have agreed with me. The latter have often misapplied or exaggerated the ideas and methods of this book to the point of parody. Some have said the ideas are fine but don't go far enough. But most of the thought here was intended to be suggestive rather than dogmatic, and the method of historical analogy can be taken only so far in architectural criticism.

Architecture as the wall between the inside and the outside becomes the spatial record of this resolution and its drama. And by recognizing the difference between the inside and the outside, architecture opens the door once again to an urbanistic point of view.

The double meanings inherent in the phenomenon both-and can involve metamorphosis as well as contradiction. I have described how the omni-directional spire of the tower of Christ Church, Spitalfields, evolves into a directional pavilion at its base, but a perceptual rather than a formal kind of change in meaning is possible. In equivocal relationships one contradictory meaning usually dominates another, but in complex compositions the relationship is not always constant. This is especially true as the observer moves through or around a building, and by extension through a city: at one moment one meaning can be perceived as dominant; at another moment a different meaning seems paramount.
