ABSTRACT
This chapter assesses 'mobility' and 'mobilities' in light of various mobility types: terrestrial, virtual and aerial in order to see whether mobility could be considered as one single concept. The three mobility types seem to widely differ from each other, beginning with the most basic feature of the physical size of mobility media and their spatial infrastructure context. The vast developments and enhancements of technology-based aerial and terrestrial mobility have turned long-established maritime mobility, using boats for functional mobility, into mostly pleasure-oriented cruises. The problem of person form for mobility is rooted in the most basic sense of mobility which is a double one: 'vertical' social mobility which implies change, and 'horizontal' spatial mobility which implies movement in space. Humans need to be mobile for some 'built-in' desires, as well as for some external attractions. Human corporeal and virtual mobility can be conceptualized through its various forms as well as through its durations of materialization.
