The aim is to theorise hope from a sociology of emotion perspective and propose a general framework for the analysis of discrete emotions – the emotive-cognitive chain of evaluation – that can be applied by analysing different types of hope. Hope is defined as the emotion of future possibility, distinct from self-confidence, faith and trust. Hope as a foreground emotion, subject to emotive-cognitive evaluation, arises in a bad present (target) as an outcome of past failed hopes. The object of hope is future improvement. Given limited agency in fundamentally uncertain circumstances, an external source of hope is located. Background import informs the assessment of the present as bad, what improvement to hope for (object) and the identification of sources. I argue that fear is a companion emotion of hope, and that a reasonable balance between hope and fear can make hope more in tune with real circumstances. Elaborating on the action continuum of hope, I propose that hope is never truly passive and that action itself generates hope. As a collective emotion, hope becomes collectively evaluated and mutually supported in a responsive social context. Responsive hope may, however, also be delusional. Different hope constructs are illustrated, drawing on findings in a project on the post-apocalyptic environmental movement. Theorising hope in the context of the climate crisis highlights the specific quality of hope as an emotion of future possibility and the significance of hope for present action and future object outcomes, its potential for social change and how we collectively create the future.
