Routine, custom, and habitual associations have always been considered the necessary foundation for human initiative and for the effective experience of individual adventure. The rise of modern technology, however, has resulted in a new type of progressive society, which may or may not provide the stability needed for human satisfaction. This is the question to which Professor Whitehead has here addressed himself. His book is written for those who seek a solution in intelligent evolution based on a faithful analysis of the observable facts, rather than in some radical departure from accustomed procedure. Recognizing that the problem centers itself somewhere in the activities of business and industry, he makes a brilliant analysis of present-day industrial civilization and reaches conclusions that will cut through the fog of wishful sentiment that invalidates most writing on this vital subject.
