This conceptual paper presents a radical humanist framing of the relationship between human needs and social welfare. It draws and develops its conceptualisation of radical humanism from the early philosophical writings of Marx in which he identified the radical constitutive needs of the human species. It seeks to translate the definitive characteristics of humanity's ‘species being’ – namely consciousness, ‘work’, sociality and historical development – into overarching claims or social rights to autonomous thinking, creative activity, mutual caring and human progress. (...) It argues for a ‘needs-first ethos’ from within which critically to evaluate welfare policy and practice, and through which to conceptualise approaches that humanise rather than dehumanise.
