“This stimulating book on the evolution of architecture in the last quarter of twentieth century penetratingly applies methods of forecasting and predication developed in the scientific disciplines to the area of the built environment. The author begins with a general consideration of forecasting methods, the ideologies that accompany them and their relevance to politics, the consumer society and revolution. He goes on to distinguish between the two basic patterns of cultural change, cyclical oscillations or reversible time, and cumulative developments or irreversible time. This section culminates in a brillant attack on architectural determinists for their fatalism the author maintaing that we need not accept the undesirable consequences of past architectural decisions as inevitable but can eliminate them and project in new combinations the desiderable aspects of the tendencies.
