Obsolete old words from seventeenth-century English villages reflect the realities of working-class life, exhausting labor, dirt, bizarre foods, magic, horses, outrageous sexism, feudal duties. New words, first appearing in print 1650-1800, reflect a middle-class culture very different from an earlier courtly culture, interested in money, coffee-houses, and self-fulfillment. The book contains chapters on pre-industrial and middle-class culture, the scientific revolution, and semantic change. They give strong evidence that new words and the new senses of old words played a key role in the British Enlightenment, its links with quantification and natural science, its tendencies towards reorganization and democracy, its redefinitions and revitalizations of women's roles, social stereotypes, the public sphere, and the very concepts of individualism, sociability, and civilization itself.
