From which evaluative foundation should we develop public policies designed to promote wellbeing among different cultural groups in different circumstances? This book seeks to advance an objective, universal theory of cultural evaluation grounded in a eudaemonic account of human wellbeing. The approach brings together a 'thick vague' conception of the good; a determinate, particularist conception of circumstance; an egalitarian moral philosophy with concessions to sufficientarianism, and a normative functionalist view of culture, to assess the value of cultural institutions to those that they affect. Engaging closely with needs and capabilities paradigms, the approach seeks to identify and explain cultural deficits in given circumstances. The applicability of the theory is illustrated through analysis of the effect of settler-indigenous relations on Aboriginal Australian people. This book is ideal for students and scholars of cultural theory and public policy.
