This chapter serves as the book's theoretical core, offering an interpretative framework that transcends the linear, developmentalist perspectives which frequently dominate island policies. The central thesis is that there is a dialectic between the linearity -produced by national and EU policies—and the cyclical nature of small islands’ everyday geographies. This dialectic can be reconciled by addressing the temporality of social life. Adopting this perspective, the concept of 'island timespace' is introduced and operationalized through routines, rhythms and seasonality. Ferry timetables are often cited and described as the primary agents shaping the temporalities of islanders. Alongside this theoretical overview, a heuristic tool is presented: the ‘spiral of island temporality’, which considers island life across three interconnected scales: the day, the week, and the season. This spiral enables an understanding of how social practices (e.g. student mobility, commuting, the seasonal job market and community life) both challenge and adapt to externally imposed temporal frameworks.
