Having set the scene, the next question to consider is this: can the model

of aesthetic judgement proposed in the previous sections be applied to the

broader spectrum of urbanism? The wider urban milieu made its appear-

ance in Part 1 with the consideration of the nature of pattern. Can the prin-

ciple of proportion also be transposed to the higher key of the city? At the

scale of the city the range of aesthetic possibilities is greatly increased, not

least because it involves the fourth dimension. Movement is an essential

component of the aesthetic agenda.
