Abstract
This chapter looks at the development of geographical accounts of mobilities and addresses some of the ontological and epistemological issues that they raise, including intersections between the 'old' and 'new' social physics, issues of scale of analysis and method, as well as the sociology of knowledge of tourism mobilities. It argues that there is great value in engaging in multiple understandings of mobilities in order to better inform method, theory and debates surrounding human behaviour in space and time, including the issue of whether there are laws of mobility. The chapter concludes by arguing that although notions of grand theory in the social sciences are usually relegated to the position of wishful positivist thinking there are nevertheless certain principles that apply to an improved understanding of accessibility and mobility issues in tourism.
