Book excerpt: This introductory history takes Scotland through two world wars and subsequent social exhaustion, through the re-energising adjustments loosely referred to as 'the sixties' to a final endgame of Union versus Independence. The novel structure of Harvie's history mirrors that of a grand engineering project, or a structure as complex as the Forth Railway Bridge: 'three periods of change rendered as towers, and two great cantilevered arches of life-in-common, over which day-to-day life proceeds'.
