The book sets out a new logic of rules, developed to demonstrate how such a logic can contribute to the clarification of historical questions about social rules. The authors illustrate applications of this new logic in their extensive treatments of a variety of accounts of social changes, analysing in these examples the content of particular social rules and the course of changes in them.

Where did passports come from? Why did 1930s stewardesses carry wrenches? And how did teetotalers shape the modern vacation? "Wanderlust" answers these questions and more, as author Laura Byrne Paquet delves into the social history of travel. Now a multi-billion dollar industry, travel is also one of the world's oldest.

Paquet follows hypochondriac Greeks to the Oracle of Delphi, checks out the bedbugs in medieval coaching inns, enjoys a Finnish sauna with a group of well-bred Victorian ladies, and relaxes on a transatlantic liner with some of England's Bright Young Things from the 1920s. In breezy style, she explains the difference between a traveller and a tourist and explores the future of travel, from grand plans for commercial space travel to underwater hotels. As the book reveals, we've always loved to travel -- the only thing that keeps changing is how we get from here to there.
