"It is impossible today to escape the need for a general awareness of the phasing of the historical process. In the past great cultures could be created unconsciously, the organic processes forming the new patterns without man's attention being drawn to their wider significance. But the unconscious phase of history is now past. The acceleration of social change which has resulted from the attention paid to specialized techniques can only be controlled by paying attention also to the general formative processes which in earlier times were unconscious. Consciousness of specialized technical methods must be balanced by consciousness of general developing forms. (p. 167)"
