A foundational assumption of social theory is that things change: structures, institutions, organisations, groups, cultures, and selves all are contingent and subject to transformation. Herein, this malleable foundation is termed transformativity, drawing attention to a specific conceptualisation of change, which predominates and displaces other accounts of change, elaborated via a typology of change that positions transformation between reconfiguration and metamorphosis. Transformativity posits society as contingent, open to reconstruction, but assuming that change acts upon a substrate, which is continuous; altered, yet (...) retaining identity through time. Transformativity is situated culturally by tracing historical conceptions of change from ancient to modern. Next, Turner's liminality, Foucault's power relations, and Butler's performativity are analysed in depth as influential contemporary models of transformativity. Furthermore, transformativist thinking animates governmentality, neo-liberal capitalism, technological thinking, and cultures of self-work. In particular, transformativity intersects with contemporary ideas of ‘experience’, incorporating notions of contingency and change into modern experimentalism. While transformativity facilitates critique and social change, this implies a gradualist model of slow purification and refinement, which may be inadequate to deal with contemporary challenges.
