"Human conduct and belief are now undergoing transformations profounder and more disturbing than any since the appearance of wealth and philosophy put an end to the traditional religion of the Greeks. It is the age of Socrates again: our moral life is threatened, and our intellectual life is quickened and enlarged, by the disintegration of ancient customs and beliefs. Everything is new and experimental in our ideas and our actions; nothing is established or certain any more. The rate, complexity, and variety of change in our time are without precedent, even in Periclean days; all forms about us are altered, from the tools that complicate our toil, and the wheels that whirl us restlessly about the earth, to the innovations in our sexual relationships, and the hard disillusionment of our souls. The passage from agriculture to industry, from the village to the town, and from the town to the city, has elevated science, debased art, liberated thought, ended monarchy and aristocracy, generated democracy and socialism, emancipated woman, disrupted marriage, broken down the old moral code, destroyed asceticism with luxuries, replaced Puritanism with Epicureanism, exalted excitement above content, made war less frequent and more terrible, taken from us many of our most cherished religious beliefs, and given us in exchange a mechanical and fatalistic philosophy of life. All things flow, and we are at a loss to find some mooring and stability in the flux."
