In this contribution to social theory, John Urry argues that the traditional basis of sociology - the study of society - is outmoded in an increasingly borderless world. If sociology is to make a pertinent contribution to the post societal era it must forget the social rigidities of the pre-global order and, instead, switch its focus to the study of both physical and virtual movement. In considering this sociology of mobilities, the book concerns itself with the travels of people, ideas, images, messages, waste products and money across international borders, and the implications these mobilities have to our experiences of time, space, dwelling and citizenship. The book extends recent debate about globalization both by providing an analysis of how mobilities reconstitute social life in uneven and complex ways, and by arguing for the significance of objects, senses, and time and space in the theorizing of contemporary life.
