This book is about change in modern culture, focussing on values rather than processes or products. It looks at five areas, as a cross-section of modern culture - nature, history, language, art and human evolution - reviewing the ways in which the central concepts of these areas have changed through the 20th century. The author explores subjects ranging from modernism and modernity in 20th century culture and the tendency of language to seek abstraction, to Bohemian empiricism, computer art and the new science of chaos.
