It is only when people begin to shake loose from their preconceptions, from the ideas that have dominated them, that we begin to receive a sense of opening, a sense of vision...That is the sort of time we live in now. We...live in an epoch in which the solid ground of our preconceived ideas shakes daily under our uncertain feet.

In the home we make certain distinctions about functions of rooms and corridors; we do not deliver the groceries straight into the baby's crib. In hospitals we do not take the food trolleys right through the operating chamber, and we rarely have the recreation room next to the convalescent room. We sort out the functions. We have to sort out the functions of the city and the streams of traffic and re-create arterial systems that allow us to breathe ... the shape, pattern and sense of community which you expect if it were a home.
